How to show please wait while ajax request process in complete -

this code working fine, want create ajax please wait while still requesting information: here code.

function products(){ if (document.getelementbyid('date').value.length == 0) { alert("please pick date"); document.getelementbyid('date').focus(); homecoming false; } var ajaxrequest; // variable makes ajax possible! try{ // opera 8.0+, firefox, safari ajaxrequest = new xmlhttprequest(); } grab (e){ // net explorer browsers try{ ajaxrequest = new activexobject("msxml2.xmlhttp"); } grab (e) { try{ ajaxrequest = new activexobject("microsoft.xmlhttp"); } grab (e){ // went wrong alert("your browser broke!"); homecoming false; } } } // create function receive info sent server ajaxrequest.onreadystatechange = function(){ if(ajaxrequest.readystate == 4){ var ajaxdisplay = document.getelementbyid('sum'); ajaxdisplay.innerhtml = ajaxrequest.responsetext; } } var usr = document.getelementbyid('usr').value; var date = document.getelementbyid('date').value; var querystring = "?usr=" + usr + "&date=" + date; ajaxrequest.open("get", "ajax_prom.php" + querystring, true); ajaxrequest.send(null); }

in page, add together div id - divajaxrequestinprogress. add together text want show while ajax request in progress div. have animated gif well. now, show when start ajax processing , hide 1 time request complete. function products(){ if (document.getelementbyid('date').value.length == 0) { alert("please pick date"); document.getelementbyid('date').focus(); homecoming false; } $("#divajaxrequestinprogress").show(); var ajaxrequest; // variable makes ajax possible! try{ // opera 8.0+, firefox, safari ajaxrequest = new xmlhttprequest(); } grab (e){ // net explorer browsers try{ ajaxrequest = new activexobject("msxml2.xmlhttp"); } grab (e) { try{ ajaxrequest = new activexobject("microsoft.xmlhttp"); } grab (e){ // went wrong alert("your browser broke!"); homecoming false; } } } // create function receive info sent server ajaxrequest.onreadystatechange = function(){ if(ajaxrequest.readystate == 4){ var ajaxdisplay = document.getelementbyid('sum'); ajaxdisplay.innerhtml = ajaxrequest.responsetext; } $("#divajaxrequestinprogress").hide(); } var usr = document.getelementbyid('usr').value; var date = document.getelementbyid('date').value; var querystring = "?usr=" + usr + "&date=" + date; ajaxrequest.open("get", "ajax_prom.php" + querystring, true); ajaxrequest.send(null); }

how can accomplish using timer class in java?

the best approach create class definitions of alphabet , equivalent in morse code. numbers can added well. way can come in text, not sos.

if sos goal, creating class might overkill still practice.

have @ docs timer class

http://docs.oracle.com/javase/7/docs/api/java/util/timer.html << updated link

this method used timer class in illustration below. sos quite possible add together forloop run sequence many seconds, , command led light.

public void schedule(timertask task, long delay, long period)

//usage of timer

import java.util.*;

public class timerdemo {

public static void main(string[] args) { // declare , create task timertask tasknew = new timertask() { // runs our task @override public void run() { system.out.println("timer running..."); } }; // declare , create timer timer mytimer = new timer(); /* schedule timer (task scheduled, delay in ms before task * execution, period in ms between successive tasks executions */ mytimer.schedule(tasknew, 500, 1000); }

}

i hope gives improve example.

im using bundle called mahapps metro, i'm trying alter style of datagrid alter default borderthickness of columnheader.

the mahapps metro datagrid command can found here: https://github.com/mahapps/mahapps.metro/blob/master/mahapps.metro/styles/controls.datagrid.xaml

the part i'm trying access custom style is:

<border x:name="backgroundborder" borderthickness="0,0,0,3" grid.columnspan="2" background="{templatebinding background}" borderbrush="{templatebinding borderbrush}" />

currently have:

<style targettype="datagridcolumnheader" x:key="geledigdheader" basedon="{staticresource metrodatagridcolumnheader}"> <setter property="horizontalcontentalignment" value="right"/> <setter property="borderbrush" value="#953735"/> </style>

this changes color want alter thickness, using property="borderthickness" not work, obviously..

well if @ style there given no explicit access borderthickness via binding. since have style can add together line

<border x:name="backgroundborder" borderthickness="0,0,0,3" grid.columnspan="2" background="{templatebinding background}" borderbrush="{templatebinding borderbrush}" borderthickness="{templatebinding borderthickness}"/>

the question have is, right way phone call jsp page or have load page request dispatcher using ajax.

to test if path correct, tried set calendar.gif in same folder , able reach context.

how can constrain image in container whole container filled much image possible?

for illustration (i not know size images be, example) - if have image container of 100x100 , image of 600x400, next conditions need met.

the image should displayed @ 150x100 the image should centred in container the overflow of image (25px left , right in example) should hidden.

please note - images of greater height width, solution needs work images of sizes, centreing both horizontally , vertically.

sadly, solution has work ie9 (as browser owners of intranet working on use), html5/css3 solutions not work.

here couple of visual examples -

i've tried various css styles -

if nest <img> within of <div> container image if absolutly place <img> on <div> unable centre vertically if wider tall (i.e. 600x400).

any suggestions gratefully received.

since mentioned has work ie9: background-size: cover that. can't utilize image img element have assign background image container.

networking - ip rule does not seem to be invoked -

i have 2 connections on local machine, 1 via eth0 (has static ip, allow 10.10.10.10), via ppp0 (has dinamic ip, illustration 10.20.30.40). both have access internet. have remote server (let's assume has ip 1.2.3.4) want connect local machine in such way packets having source address 10.10.10.10 (eth0) should go through eth0, while having 10.20.30.40 (ppp0) source address should go through ppp0.

preliminary deleted ip rule main route table in order prevent packets beingness treated rule.

after that, created 2 route tables, 1 eth0 (named eth) , ppp0 (named ppp). added routes these tables follows:

ip route add together default dev ppp0 table ppp ip route add together default dev eth0 table eth

then added ip rules followings:

ip rule add together 10.10.10.10 lookup eth ip rule add together 10.20.30.40 lookup ppp

and doesn't work. however, when utilize ip rule add together all instead of pointing specific ip works (sure, packets go through 1 interface in case). so, seems ip rule not invoked when specify ip.

what reason of such unusual behavior?

does have ideas?

i found reason. cause of problem programme (written usage of qt qtcpsocket::bind()) binds socket appropriate interface, not routing settings. not unknown reason. tried using native linux socket functions , runs clockwork.

How to use Verdana Font in Stamper (iText PDF) -

How to use Verdana Font in Stamper (iText PDF) -

i want utilize verdana font while stamping pdf file itext pdf. original file uses verdana, isn't alternative in class basefont.

here function create font right now:

def standardstampfont() { homecoming basefont.createfont(basefont.helvetica, basefont.winansi, false) }

i'd alter verdana font, exchanging part basefont.helvetica "verdana" doesn't work.

any idea? in advance!

as documented, itext supports standard type 1 fonts, because itext ships afm file (adobe font metrics files). itext has no thought font metrics of other fonts (verdana isn't standard type 1 font). need provide path verdana font file.

basefont.createfont("c:/windows/fonts/verdana.ttf", basefont.winansi, basefont.embedded)

note alter false basefont.embedded because same problem have on side, occur on side of person looks @ file: pdf viewer can render standard type 1 fonts, may not able render other fonts such verdana.

caveat: hard coded path "c:/windows/fonts/verdana.ttf" works me on local machine because font file can found using path on local machine. code won't work on server host itext site, though (which linux server doesn't have c:/windows/fonts directory). using hard coded path way of example. should create sure font nowadays , available when deploy application.

dataset - Converting cross-sectional data into an adjacency matrix in R -

dataset - Converting cross-sectional data into an adjacency matrix in R -

i trying convert cross-sectional info adjacency matrix, want analyze how variables nowadays social network analysis. in case empirical examples help logic, it's analogous presenting 4 people selection of 3 objects; can take 0 3 of objects. i'd analyze how commonly different objects chosen , visualize network of preferences.

the info set cross-sectional data, below:

id1 <- c(1,0,0) id2 <- c(1,0,1) id3 <- c(1,1,1) id4 <- c(0,0,0) ids <- c("1","2","3","4") df <- data.frame(rbind(id1, id2, id3, id4)) df <- cbind(ids, df) colnames(df) <- c("id", "var1", "var2", "var3")

i'd create weighted adjacency matrix var1, var2 , var3, each cell containing total number of times 2 variables occur among observations.

so basic procedure thinking create separate matrix each row (each id number) 1 or 0 each cell indicating whether or not both variables nowadays id. , add together these matrices together, final matrix gives total number of joint appearances.

i've been looking around , haven't quite gotten right. thought of using outer, it'd need work each column in sequence. reply pretty close, wasn't sure how adding values. ended list of matrices, values didn't correspond initial data- convert categorical info in info frame weighted adjacency matrix. , reply close, although seemed have different type of data. gave me adjacency matrix based on ids- http://r.789695.n4.nabble.com/conversion-to-adjacency-matrix-td794102.html

here messy code manually create matrix 1 observation, sense i'm going (using vector representing first id observation)

id1 <- c(1,0,0) var1 <- id1[[1]] var2 <- id1[[2]] var3 <- id1[[3]] onetwo <- var1 * var2 onethree <- var1 * var3 twothree <- var2 * var3 oneone <- var1 * var1 twotwo <- var2 * var2 threethree <- var3 * var3 rows1 <- rbind(oneone, onetwo, onethree) rows2 <- rbind(onetwo, twotwo, twothree) rows3 <- rbind(onethree, twothree, threethree) df2 <- cbind(rows1, rows2, rows3)

this not ideal, actual dataset has 198 observations , 33 variables, looping or utilize of apply functions inefficient.

i can't tell if i'm making more hard needs be, or if i'm trying forcefulness info wasn't meant do. if has run sort of task before, please allow me know. there way create desired adjacency matrix directly? should transfer border list first, , there way that? there code create first step(creating matrix each row of dataframe) more efficient?

thanks help,

i'm not sure if understand question, want?

nc=33 nr=198 m3<-matrix(sample(0:1,nc*nr,replace=true),nrow=nr) df3<-data.frame(m3) m3b <-matrix(0,nrow=nc,ncol=nc) for(i in seq(1,nc)) { (j in seq(1,nc)) { t3<-table(df3[,i],df3[,j]) m3b[i,j] = t3[2,2] # t3[2,2] contains count of df3[,i] = df3[,j] = 1 # or # t3 = sum(df3[,i]==df3[,j] & df3[,i] == 1) # m3b[i,j] = t3 } }

or, if want sum of product, gives same result if 1 or 0

m3c <-matrix(0,nrow=nc,ncol=nc) for(i in seq(1,nc)) { (j in seq(1,nc)) { sv=0 (k in seq(1,nr)) { vi = df3[k,i] vj = df3[k,j] sv=sv+vi*vj } m3c[i,j] = sv } }

floating point - How to display float value on LCD 16x2 -

floating point - How to display float value on LCD 16x2 -

i want display float value on lcd. have using avr5.1 compiler , using function snprintf convert float value ascii. gives output on proteus "?".

here code using; have include library of printf_flt:

temp1=adch; // measuring voltage temp=(temp1*19.53)*2.51; lcd_goto(1,1); snprintf(buffer,6, "%2.2f", temp); lcd_data1(buffer); lcd_data1("mv"); percent=(temp-11500); lcd_goto(2,2); snprintf(buffer1,4, "%2.2f", percent); lcd_data1(" "); lcd_data1(buffer1); lcd_data1("%");

here image of output:

many development tools have multiple versions of printf , related functions, back upwards differing levels of capabilities. floating-point math code bulky , complicated, including features aren't used waste lot of code space.

some tools automatically seek figure out options need included, aren't , require programmer explicitly select appropriate printf version using command-line arguments, configuration files, or other such means. may necessary create compiler include version of printf-related functions supports %f specifier, or else utilize other means of formatting output. own preferred approach convert value scaled integer (e.g. 100x desired value) , write method output digits, least-significant first, , insert period after outputting number of digits. like:

uint32_t acc; uint8_t divmod10() { uint8_t result = acc % 10; acc /= 10; } // output value in acc using 'digits' digits, decimal point shown after dp. // if dp greater 128, don't show decimal point or leading zeroes // if dp less 128 greater digits, show leading zeroes void out_number(uint8_t digits, uint8_t dp) { acc = num; while(digits-- > 0) { uint8_t ch = divmod10(); if (ch != 0 || (dp & 128) == 0) out_lcd(ch + '0'); else out_lcd(ch); if (--dp == 0) out_lcd('.'); } }

since lcd modules can configured receive info right-to-left, outputting numbers in form can useful simplification. note seldom utilize "printf"-family functions on little microcontrollers, since code above much more compact.

you passing in wrong argument preprocess function, guess calling python shell.

you not suppose pass in image file name, rather numpy array. seems called proprocess function , passed in "test.jpg" in python shell. if want test preprocess function, do

test_img = cv2.imread("test.jpg") preprocess(test_img)

ios - Tokenize an NSString for filtering data (search) -

ios - Tokenize an NSString for filtering data (search) -

i'm trying implement search filtering info source used populate uitableview.

basically, i'm trying allow people set in multiple words , split 1 string tokens , iterate through each object in datasource see if can find of search tokens anywhere in object's properties or sub-properties.

if user types in multiple words separated spaces, trivial case of using -componentsseparatedbystring:.

i'm trying, however, solve case user might set in comma-separated list of items.

so, easy entry tokenize this:

"word1 word2 word3"

i want able tokenize this:

"word1, word2, word3"

the problem see that, because don't assume user come in commas, can't replace/remove white space.

i see kludgy ways implement want, consists of splitting first on white space, iterating array, splitting on commas, iterating overall array, removing "empty" tokens. think work, hoping more elegant way this, since might decide add together 3rd delimiter @ point, create solution exponentially more complex.

so far, i'm intrigued using nscharacterset in combination -componentsseparatedbycharactersinset. i'm having problem method, though.

here's i'm trying far:

nsmutablecharacterset *delimiters = [nsmutablecharacterset charactersetwithcharactersinstring:@","]; [delimiters addcharactersinstring:@" "]; nsarray *tokens = [searchtext componentsseparatedbycharactersinset:delimiters];

the problem i'm encountering this:

suppose searchtext (above) "word,". in case, tokens array becomes this:

[@"word", @""]

so, trying out, appear (at first glance) still have iterate tokens array remove empty items. again, possible, have feeling there's improve way.

is there improve way? misusing nscharacterset?

use enumeratesubstringsinrange:options:usingblock:, , pass nsstringenumerationbywords option. separate string individual words, , strip out spaces, commas, semicolons, etc. instance, code,

- (void)viewdidload { [super viewdidload]; nsmutablearray *words = [nsmutablearray new]; nsstring *text = @"these , some, words commas; semi colons: colons , period."; [text enumeratesubstringsinrange:nsmakerange(0, text.length) options:nsstringenumerationbywords usingblock:^(nsstring *substring, nsrange substringrange, nsrange enclosingrange, bool *stop) { [words addobject:substring]; }]; nslog(@"%@", words); }

gives output,

Sorting arrays manually in php without using sort() -

Sorting arrays manually in php without using sort() -

help. stucked in logic , procedures in printing sorted array lists without using sort().

<?php $item = array(2, 1, 3); $item_length = count($item); ($counter = 0; $counter < $item_length; $counter++) { if ($item[$counter] <= $item[$counter + 1]) { print $item[$counter]; // should do?? } } ?>

here solution using bubble sort

<?php $item = array(2, 1, 4,3,5,6); $item_length = count($item); ($counter = 0; $counter < $item_length-1; $counter++) { ($counter1 = 0; $counter1 < $item_length-1; $counter1++) { if ($item[$counter1] > $item[$counter1 + 1]) { $temp=$item[$counter1]; $item[$counter1]=$item[$counter1+1]; $item[$counter1+1]=$temp; } } } //you can print array using loop print_r($item); ?>

c# - The type or namespace name 'BundleCollection' could not be found (are you missing a using directive or an assembly reference?) -

so, have mvc 4 project in c# , using visual studio web 2012 express.

i cannot compile projecto due error: type or namespace name 'bundlecollection' not found (are missing using directive or assembly reference?)

normally, mean library missing. after making quick search on net used nuget install microsoft.aspnet.web.optimization, still did not work.

what makes intriguing me bundlecollections should known application deafult. can imagine have added dependency messed up, can't know sure.

how can prepare problem? missing here?

code:

using system; using system.web; using system.web.optimization; namespace dockis { public class bundleconfig { // more info on bundling, visit http://go.microsoft.com/fwlink/?linkid=254725 public static void registerbundles(bundlecollection bundles) { iitemtransform cssfixer = new cssrewriteurltransform(); bundles.add(new scriptbundle("~/bundles/jquery").include( "~/scripts/jquery-{version}.js")); //... } } }

edit

after checking references folder tried running command install-package system.web.optimization, cannot install package. next error:

install-package : 1 or more errors occurred. @ line:1 char:16 + install-package <<<< system.web.optimization + categoryinfo : notspecified: (:) [install-package], aggregateexception + fullyqualifiederrorid : nugetcmdletunhandledexception,nuget.powershell.commands.installpackagecommand

what odd, fact running install-package system.web.optimization.less works, , fixes depencie problems, not of them. believe need first command work.

what doing wrong?

there no clear reply question. managed prepare project re-creating it, , downloading dlls in different order, closing , re-opening visual studio several times while doing it.

aparently there conflict between of packages, impossible guess until had re-created project scratch again.

running install-package microsoft.aspnet.web.optimization did solve problem after clean install however, recommend it.

i give thanks help.

i trying plot simple x,y line plots info in loop. code generate hundreds of such plots , thought save these plots in thumbnail size image (something 200 x 200 pixels, dpi wont matter) , embed in excel file along data. when plot through ggplot2 looks fine when want save it, either cropped image showing part of image or narrow plot mismatched sizes of labels/texts. if set scale 2 looks right not fit criteria.

my info frame looks this.

swift - Change Spacing Between UIBarButtonItems in iOS 8 -

swift - Change Spacing Between UIBarButtonItems in iOS 8 -

i have uinavigationitem on view controller, , trying cut down spacing between 2 rightbarbuttonitems. here of code:

// create 2 uibarbuttonitems allow item1:uibarbuttonitem = uibarbuttonitem(customview: view1) allow item2:uibarbuttonitem = uibarbuttonitem(customview: view2) var fixedspace:uibarbuttonitem = uibarbuttonitem(barbuttonsystemitem: uibarbuttonsystemitem.fixedspace, target: nil, action: nil) fixedspace.width = -20.0 // add together rightbarbuttonitems on navigation bar viewcontroller.navigationitem.rightbarbuttonitems = [item2, fixedspace, item1]

as can seen, using fixedspace uibarbuttonitem, not changing spacing reason. have thought subclassing either uinavigationitem or uibarbuttonitem can set spacing accordingly, couldn't seem find methods override alter spacing between items.

any insight on how solve problem appreciated!

thanks @fogmeister's help, figured out width of view1 , view2 objects, uibuttons, large. why there abnormal spacing between them. here final code:

// first button's image var view1img:uiimage = uiimage(named: "image1")! // create first button var view1:uibutton = uibutton(frame: cgrect(x: 0, y: 0, width: view1img.size.width, height: view1img.size.height)) // sec button's image var view2img:uiimage = uiimage(named: "image2")! // create sec button var view2:uibutton = uibutton(frame: cgrect(x: 0, y: 0, width: view2img.size.width, height: view2img.size.height)) // create 2 uibarbuttonitems allow item1:uibarbuttonitem = uibarbuttonitem(customview: view1) allow item2:uibarbuttonitem = uibarbuttonitem(customview: view2) // set 26px of fixed space between 2 uibarbuttonitems var fixedspace:uibarbuttonitem = uibarbuttonitem(barbuttonsystemitem: uibarbuttonsystemitem.fixedspace, target: nil, action: nil) fixedspace.width = 26.0 // set -7px of fixed space before 2 uibarbuttonitems aligned border var negativespace:uibarbuttonitem = uibarbuttonitem(barbuttonsystemitem: uibarbuttonsystemitem.fixedspace, target: nil, action: nil) negativespace.width = -7.0 // add together rightbarbuttonitems on navigation bar viewcontroller.navigationitem.rightbarbuttonitems = [negativespace, item2, fixedspace, item1]

i create background image first uibutton , utilize size create frame uibutton. perform same actions sec uibutton. then, create uibarbuttonitems 2 uibuttons. after that, create 26px of fixed space , -7.0px of fixed space. purpose of former create amount of space between 2 buttons. purpose of latter move uibarbuttonitems on right. then, add together of uibarbuttonitems rightbarbuttonitems in particular order want.

it works great now! of help, fogmeister!

firefox addon - Open page from main.js and pass data to it -

firefox addon - Open page from main.js and pass data to it -

i trying create simple test addon 1 thing: open html page (located in info folder) main.js, pass generated json can display. i've figured out complex way using message-passing , cloning unsafewindow.options, there must simpler way?

ps. i'm happy utilize 'addon-page' module if right way it...

a simple template opening tab, when tab ready, attach content scripts, pass parameters, , setup message handlers:

in addon module:

var resourceurl=require("sdk/self").data.url; require("sdk/tabs").open({ url:resourceurl("index.html"), onready:function(tab){ var worker=tab.attach({ contentscriptfile:["support.js","content.js"].map(resourceurl), contentscriptoptions:{}, //parameters passed content script }); worker.port.on("ready",function(msgin){ worker.port.emit("acknowledge",msgout); }); } });

and in content script; send "ready" message , recieve "acknowledge" message:

self.port.on("acknowledge",function(msgin){}); self.port.emit("ready",msgout);

there might changes handling of parameters url and/or contentscriptfile, such relative paths allowed without need require("sdk/self").data.url. not sure if speculation/proposal or if it's implemented; haven't checked.

also think addon-page depreciated , hasn't worked since upgrade australis ui (i.e. navigation bar no longer hidden special uris about:addons).

opencl - Difference between two ways of measuring kernel execution times -

opencl - Difference between two ways of measuring kernel execution times -

i have n separate opencl kernels run synchronously in sequential fashion. sec kernel uses results first kernel, 3rd kernel uses sec kernel, , etc.

i measured total "execution" time kernels in 2 different ways:

1) associate each kernel individual event , measure time each kernel separately subtracting start time end time of each event. total time computed adding times events of kernels. in case, event wait method called after executing each kernel.

2) in 1), associate each kernel event (n kernels , n events). then, phone call event wait methods @ end after executing kernels (namely, event wait calls followed series of kernel calls). total execution time obtained subtracting start time of first event end time of lastly event.

the difference between total times 1) , 2) quite significant: ~20% of total execution time. 20% lost? associated (en)queuing multiple kernels?

how go reducing "overhead"? cut down overhead write larger kernel cramming kernels single big kernel restructuring kernels?

thanks!

C++ Perincrement Undefined Operation vs C -

C++ Perincrement Undefined Operation vs C -

i have line of code:

front = (++front) % size;

in c no warnings in c++ warning operation on front end may undefined [-wsequence-point]. how preincrement usage cause undefined behavior? in mind, line unambiguous , interpreted as:

increment front mod front end size assign new value front.

is compiler throwing blanket warning?

p.s. understand warning if doing front = front++; or heaven forbid front = front++ + front++;.

edit: warning produced in codeblocks on windows 64 using gcc (tdm-1) 4.6.1

the old sequencing rules had border cases order of operations defined still technically undefined behavior. c++11 , c11 has been fixed replacing sequence point requirements 'sequenced-before' , 'sequenced-after' relations.

your illustration happens such case. if you're getting warnings in c11 or c++11 mode warning hasn't been updated new rules yet. in before c , c++ modes warning correct. if you're not getting warnings in before modes weren't implemented, , that's okay 'no diagnostic required'.

at same time, line can written more , right under old rules:

front = (front + 1) % size;

the web services can filter on fields of primary view of screen, in case ar303000.customersummary. if seek filter on else, scheme doesn't throw exception, instead silently discards filter.

if need able filter information, suggest create generic enquiry joins on tables need, , utilize gi screen through web services other enquiry screen.

what null macro here? leave if body empty or write ; (like did).

if you, include such temperatures 40, 30, 20 , 10. isn't clear why omit temperatures 5, 6, 7, 8 , 9.

with little change, logic must correct:

say, if temp 27, discard <50, <40, <30 , when discards <20, figures out 27 in range [20 .. max]. there's no need in these && temp < 50 - have verified temp if more 50 , got negative result 27 (in previous if condition), don't heave again.

if (temp >= 50) { ac = 100% } else if (temp >= 40) { ; // alter nil } else if (temp >= 30) { ac = 50% } else if (temp >= 20) { ; } else if (temp >= 10) { ac = 25%; } else { // temp may -1, take consideration. ac = 0%; }

db2 luw - Summing and counting across multiple tables in SQL -

i have 3 tables need select , summarize data.

table: thought reference sl 128 sl1 200 sl1 201 sl2 205 sl3 table: acct1 idea_ref accts 128 5 128 2 200 3 205 4 table: acct2 idea_ref accts 201 3 205 4 205 3

what need pull summary sorted sl totals accts field of both tables.

here sql using far:

select i.sl sl, count(distinct i.reference) no, sum(case when a1.idea_ref=i.reference a1.accts else 0 end) acct1, sum(case when a2.idea_ref=i.reference a2.accts else 0 end) acct2 thought left bring together acct1 a1 on a1.idea_ref=i.reference left bring together acct2 a2 on a2.idea_ref=i.reference a2.idea_ref in i.reference or a1.idea_ref in i.reference grouping i.sl

the problem finding when there multiple values in acct1 , acct2 tables reference thought table. here results query:

sl no acct1 acct2 sl1 2 10 0 sl2 1 0 3 sl3 1 8 7

the sl3 line adds acct1 , acct2 values 2 times. can't seem find right way add together them appropriate number of times.

the desired output is:

sl no acct1 acct2 sl1 2 10 0 sl2 1 0 3 sl3 1 4 7

any help much appreciated.

you hare asking 3 separate aggregates, you're trying compute them in single query.

to no (count of distinct items) can do

select sl, count(*) no thought grouping sl

to acct1 item can do:

select sl, sum(accts) acct1 thought bring together acct1 on idea.reference = acct1.idea_ref grouping sl

in manner can acct2

select sl, sum(accts) acct2 thought bring together acct2 on idea.reference = acct2.idea_ref grouping sl

then, need bring together these aggregate queries on sl result set. because have missing entries in of aggregates, need left in left join , coalesce() items.

sql fiddle

here's on query

select q.sl, no, coalesce(acct1,0) acct1, coalesce(acct2,0) acct2 ( select sl, count(*) no thought grouping sl ) q left bring together ( select sl, sum(accts) acct1 thought bring together acct1 on idea.reference = acct1.idea_ref grouping sl ) r on q.sl = r.sl left bring together ( select sl, sum(accts) acct2 thought bring together acct2 on idea.reference = acct2.idea_ref grouping sl ) s on q.sl = s.sl

the result looking for:

| sl | no | acct1 | acct2 | |-----|----|-------|-------| | sl1 | 2 | 10 | 0 | | sl2 | 1 | 0 | 3 | | sl3 | 1 | 4 | 7 |

see how works? have each aggregate separately.

if you're using dbms doesn't know join ... using() syntax, set in on q.sl = r.sl or appropriate on clause instead. see edit, , see fiddle: http://sqlfiddle.com/#!2/63aa1/3/0

the problem launched app seems tied java process, gets terminated when java app exits. want leave other app running.

edit: made error above description. launched app not terminated.

the problem after original app exits, can not start 1 time again until launched app terminates. original app (and launched app) both launch4j generated .exe's.

so, how can maintain launched app preventing total exit original app?

(oh, , throw monkeywrench it, launched app uses 32bit jvm, while original app running in 64bit jvm.)

while shell command trick might work, did find easier way.

desktop.getdesktop().open("app name");

apparently launches app in way not remain tied original program.

javascript - just one of the ng-bind-html in page work -

i write angularjs application , have block of code first html-bind-html works me

<div ng-bind-html='newstitle'> <div ng-bind-html='newsdetail'></div> </div>

when alter priority :

<div ng-bind-html='newsdetail'> <div ng-bind-html='newstitle'></div> </div>

it shows newsdetail value. how many ng-bind-html per page can declare? why sec value doesn't show?

i guess understand problem.

<div ng-bind-html='newstitle'> <!-- replace content of div $scope.newstitle --> <div ng-bind-html='newsdetail'> <!-- won't appear, because has been removed ng-bind-html='newstitle' --> </div> </div>

look comments in code. if set newsdetails in first place, binded html ($scope.newsdetail) replace current content aswell.

in word, ng-bind-html replace current content of element binded html provide. shouldn't set html in elements.

you have :

<div class="news"> <div ng-bind-html='newstitle'></div> <div ng-bind-html='newsdetail'></div> </div>

Silverstripe 3 - Unable to implement controller access security from CMS -

Silverstripe 3 - Unable to implement controller access security from CMS -

good afternoon,

i'm still new silverstripe , i'm trying figure out simple tasks.

currently, i'm trying implement security restrictions page controller function created within dataobject , configured via cms.

however, whether or not grant user access view object, user sees anyhow.

see illustration below:

class mycomponent extends dataobject implements permissionprovider{ ///>... snippet not total class ... ///>@override public function canview($member = null){ homecoming permission::check('component_view'); }//canview /** * \brief rest of permission functions follow same format above * i.e: canedit, candelete, cancreate */ ///>@override function providepermissions(){ homecoming array( 'component_view' => 'can view component object', 'component_edit' => 'can edit component object', 'component_delete' => 'can delete component object', 'component_create' => 'can create component object', ); }//providepermissions }//class

okay, class above works great; can toggle permissions on|off within grouping user cms admin section.

here's problem at, see code below:

///>controller class snippet class my_controller extends page_controller{ public function listmycomponents(){ $components = mycomponent::get()->filter(array('status' => 'enable')); ///>note: how can check see if user has access view component??? ///> i've tried, member::canview(member::currentuser()); doesn't work! homecoming $components; }//listmycomponents }//class ///>ss template file snippet <% if listmycomponents %> <% loop listmycomponents %> $title <% end_loop %> <% end_if %>

thanks assistance.

i've figured out. basically, can permission::check within controller well. see below code solution:

public function listmycomponents(){ $components = null; if(permission::check('component_view')){ $components = mycomponent::get()->filter(array('status' => 'enable')); } homecoming $components; }//listmycomponents

thanks though, may have been researching solve this.

removing autoheight: true, solved problem.

Trouble with binary string in javascript above character code 128 -

Trouble with binary string in javascript above character code 128 -

so i'm trying create , save binary file locally in javascript using library: https://github.com/eligrey/filesaver.js/

it bit tricky because using gamemaker studio, , ways can interact javascript bit limited, here's setup.. other actual filesaver.js github repo, js code this:

var ildablob = new array(); toarray = function(argument0, argument1) { ildablob[argument0] = string.fromcharcode(argument1); homecoming 1; } save = function(argument0) { var blob = new blob(ildablob, {type: "application/octet-stream"}); saveas(blob, argument0); homecoming 1; }

basically, thought first fill array individual bytes using character codes create binary string, made blob , saved. works binary values below 128, not above, because of charset issue.. how can prepare this?

for example, if seek filling array incrementing 0-255, content of resulting binary file, can see after 128 bytes characters create 2 bytes each, not one, , it's wrong:

00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 31 32 33 34 35 36 37 38 39 3a 3b 3c 3d 3e 3f 40 41 42 43 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f 50 51 52 53 54 55 56 57 58 59 5a 5b 5c 5d 5e 5f 60 61 62 63 64 65 66 67 68 69 6a 6b 6c 6d 6e 6f 70 71 72 73 74 75 76 77 78 79 7a 7b 7c 7d 7e 7f c2 80 c2 81 c2 82 c2 83 c2 84 c2 85 c2 86 c2 87 c2 88 c2 89 c2 8a c2 8b c2 8c c2 8d c2 8e c2 8f c2 90 c2 91 c2 92 c2 93 c2 94 c2 95 c2 96 c2 97 c2 98 c2 99 c2 9a c2 9b c2 9c c2 9d c2 9e c2 9f c2 a0 c2 a1 c2 a2 c2 a3 c2 a4 c2 a5 c2 a6 c2 a7 c2 a8 c2 a9 c2 aa c2 ab c2 ac c2 advertisement c2 ae c2 af c2 b0 c2 b1 c2 b2 c2 b3 c2 b4 c2 b5 c2 b6 c2 b7 c2 b8 c2 b9 c2 ba c2 bb c2 bc c2 bd c2 c2 bf c3 80 c3 81 c3 82 c3 83 c3 84 c3 85 c3 86 c3 87 c3 88 c3 89 c3 8a c3 8b c3 8c c3 8d c3 8e c3 8f c3 90 c3 91 c3 92 c3 93 c3 94 c3 95 c3 96 c3 97 c3 98 c3 99 c3 9a c3 9b c3 9c c3 9d c3 9e c3 9f c3 a0 c3 a1 c3 a2 c3 a3 c3 a4 c3 a5 c3 a6 c3 a7 c3 a8 c3 a9 c3 aa c3 ab c3 ac c3 advertisement c3 ae c3 af c3 b0 c3 b1 c3 b2 c3 b3 c3 b4 c3 b5 c3 b6 c3 b7 c3 b8 c3 b9 c3 ba c3 bb c3 bc c3 bd c3 be

instead of using string, you'd improve off using uint8array (meaning array of unsigned bytes in range 0–255); see https://developer.mozilla.org/en-us/docs/web/javascript/reference/global_objects/uint8array. example:

ildablob[argument0] = new uint8array(1); ildablob[argument0][0] = argument1; ... var blob = new blob(ildablob, {type: "application/octet-stream"});

also, incidentally — argument0 , argument1 terrible variable-names. mention you're constrained gamemaker; reason this? seems there should way prepare that.

scala - Method that add and remove an element from a List -

scala - Method that add and remove an element from a List -

i'm writing method take list: list[(string, int)] , x:(string, int) , n: int parameters , homecoming list[(string, int)] list parameter represents input list, x element represents element add together list, n represents maximum dimension of list.

the method has next behavior:

first of check if list has n elements. if list has less n elements, method add together x elements list. otherwise if list contain elements less x, method remove minimum element list, , add together x element list.

i've implemented method following:

def method(list: list[(string, int)], x: (string, int), n: int) = { if(list.size < n) list :+ x else { var index = -1 var min = 10000000//some big number for(el <- 0 list.size) { if(list(el)._2 < x._2 && list(el)._2 < min) { min = list(el)._2 index = el } } if(index != -1) { val newlist = list.drop(index) newlist :+ x } else list } }

exist way express behavior in more clean way??

first, corrected version of posted (but appears, not intended)

def method(list: list[(string, int)], x: (string, int), n: int) = { if(list.size < n) list :+ x else { var index = -1 for(i <- 0 until list.size) { val el = list(i) if(el._2 < x._2) index = } if(index != -1) { val (before, after) = list.splitat(index) val newlist = before ++ after.tail newlist :+ x } else list } }

and tests

val l1 = list(("one", 1)) val l2 = method(l1, ("three", 3), 2) //> l2 : list[(string, int)] = list((one,1), (three,3)) val l3 = method(l2, ("four", 4), 2) //> l3 : list[(string, int)] = list((one,1), (four,4)) val l4 = method(l2, ("zero", 0), 2) //> l4 : list[(string, int)] = list((one,1), (three,3))

neater version (but still not meeting spec mentioned in comment op)

def method(list: list[(string, int)], x: (string, int), n: int) = { if (list.size < n) list :+ x else { val (before, after) = list.span(_._2 >= x._2) if (after.isempty) list else before ++ after.tail :+ x } }

another version removes minimum, if that's less x.

def method(list: list[(string, int)], x: (string, int), n: int) = { if (list.size < n) list :+ x else { val smallest = list.minby(_._2) if (smallest._2 < x._2) { val (before, after) = list.span(_ != smallest) before ++ after.tail :+ x } else list } }

and test results

val l1 = list(("one", 1)) val l2 = method(l1, ("three", 3), 2) //> l2 : list[(string, int)] = list((one,1), (three,3)) val l3 = method(l2, ("four", 4), 2) //> l3 : list[(string, int)] = list((three,3), (four,4)) val l4 = method(l2, ("zero", 0), 2) //> l4 : list[(string, int)] = list((one,1), (three,3))

but in comment, improve utilize method processes whole sequence of xs , returns top n.

android - Sony Smartwatch 2 manage vibration on receiving notification -

i'm using sony addon sdk develop notification app on smart watch 2.

i've managed work (watch vibrates when phone gets notification), havn't got way modify vibration length.

is there way manage vibration on receiving notification? in shorter vibration, longer vibration, etc..

the default vibration seem bit long, want modify it's length.

any help appreciated.

short answer: there no possibility configure vibration of standard notification, using notification api.

you can create custom vibration pattern, in smartwatch2 extension using command api. available after user starts extension, not notification purpose. start vibration pattern running extension, can use: controlextension.startvibrator(int onduration, int offduration, int repeats)

git - How do I get commits from a merged and reverted PR into a new one? -

git - How do I get commits from a merged and reverted PR into a new one? -

to create long story short, in next situation:

a feature branch created, worked on while collecting 30 commits, , merged master. merge reverted through github's web interface (by creating new pr reverted effects of old one).

now, have fixed problems caused revert merge, , i'd create new pr both of 30 or commits original pr , couple of more fix.

i've based feature-fix branch on (unmerged) head of feature branch, committed couple of times more , pushed create pr - reason, pr picks new commits, not old ones.

how include old commits in new pr?

i have force access repo (we're using shared repo model) operations don't require force-push master ok.

simplified git history:

* [feature-fix] <-- branch want pull | * [master] | * [merge revert pr] * |\ | | * [revert pr] * |/ <-- first commit included in new pr github | * [merge pr] |/| * | [feature] <-- original pr came | | * | <-- want these commits, included in old pr, included * | in new pr too. | | * | <-- started work on feature here. first commit want include. \| * <-- mutual ancestor between `feature-fix` , `master`, far can see

if understanding correctly need following.

git checkout master git revert sha_of_merge_revert_pr git merge feature-fix

the key step reverting commit reverted merge. sha removed changes, preserved merge history why seeing new commits.

android - Socket.io client on Google Glass -

android - Socket.io client on Google Glass -

im trying allow google glass , android phone connect nodejs server im running on computer, can send messages android phone google glass.

for im using koush's androidasync library, works great on android phone , have absolutely no problem connecting phone nodejs server library.

however, same code doesnt seem work on google glass. google glass connect, because on connection eventhandler of nodejs server triggered, doesnt seem trigger of connectcallback functions on google glass.

here code im using in google glass app:

socketioclient.connect(asynchttpclient.getdefaultinstance(), "http://192.168.1.229:5000", new connectcallback() { @override public void onconnectcompleted(exception ex, socketioclient client) { log.i("socket", "connection completed"); if (ex != null) { ex.printstacktrace(); return; } client.setstringcallback(new stringcallback() { @override public void onstring(string string, acknowledge acknowledge) { log.d("socket", string); } }); client.setjsoncallback(new jsoncallback() { @override public void onjson(jsonobject jsonobject, acknowledge acknowledge) { log.d("socket", jsonobject.tostring()); } }); client.on("event", new eventcallback() { @override public void onevent(jsonarray jsonarray, acknowledge acknowledge) { log.i("data: ", jsonarray.tostring()); gson gson = new gson(); } }); mclient = client; } });

}

as can see, im trying log "connection completed" in "onconnectcompleted" function, never fires , nil ever logged.

i find rather strange, same code work on android phone , "connection completed" logged when run bit of code on android phone. strangest thing node server picks google glass on connection event triggered on server when glass connects.

so, can help me find out why google glass apparently connecting nodejs server, not triggering events when connects. (not triggering connectcallback functions, "connection completed" never logged)?

thanks in advance,

bram

i facing same issue here , noticed although glass showed connected wifi network, wasn't. tried adb shell netcfg on , surprise wlan0 interface had no ip assigned. reconnected wifi network 1 time again , started work fine.

the weird thing though expecting sort of error logged (even though using different socket.io client). believe case timeout didn't expire (connection/socket timeout) still attempting connect , didn't fail in time see log entry. guess these libraries have relatively high connection timeout set default, wouldn't see error before many seconds go by.

what need able deserialize messagea?

as far know, default setting of easynetq requires type of serialized object consistent between applications. example, can send known .net type string:

bus.publish<string>("excellent.");

and happy on both projects.

you can utilize own message if set common library (dll). since specially mentioned reside in different projects, i'd suggest serialize , cast objects yourself.

easynetq uses interally newtonsoft json.net serialize objects this. can see, message has been serialized as:

message: {"text":"hello world"}

to yourself, still need add together reference json.net because easynetq hides reference using ilrepack.

this should work:

bus.publish<string>(jsonconvert.serializeobject(new messagea { text = "hello world" }));

and

bus.subscribe<string>("", handleclusternodes); private static void handleclusternodes(string obj) { var mymessage = (messageb)jsonconvert.deserializeobject<messageb>(obj); console.writeline(mymessage.text); }

but you'll lose attribute based routing , might want modify methods.

if want maintain using basic methods, can set topic this:

bus.publish<string>(jsonconvert.serializeobject(new messagea { text = "hello world" }), "topic.name"); bus.subscribe<string>("", handleclusternodes, new action<easynetq.fluentconfiguration.isubscriptionconfiguration>( o => o.withtopic("topic.name")));

but have complete control, need utilize advanced api;

var yourmessage = new message<string>(jsonconvert.serializeobject(new messagea { text = "hello world" })); bus.advanced.publish<string>(new exchange("yourexchangename"), "your.routing.key", false, false, yourmessage);

and on subscriber part:

iqueue yourqueue = bus.advanced.queuedeclare("anothertestmessagesqueue"); iexchange yourexchange = bus.advanced.exchangedeclare("yourexchangename", exchangetype.topic); bus.advanced.bind(yourexchange, yourqueue, "your.routing.key"); bus.advanced.consume<string>(yourqueue, (msg, info) => handleclusternodes(msg.body));

which same original rabbitmq c# client api.

detailed analysis:

the main problem exception:

easynetq.easynetqexception: cannot find type easynetqsample.programa+messagea:easynetqsample

this thrown easynetq because cannot find special class on endpoint.

if @ source code of typenameserializer.cs, see

var type = type.gettype(nameparts[0] + ", " + nameparts[1]); if (type == null) { throw new easynetqexception( "cannot find type {0}", typename); }

this tried find easynetqsample.programa.messagea type on second project, while knows easynetqsample.programb.messageb.

alternatively, can roll out own custom iserializer or set itypenameserializer default serializer haven't tried this.
