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}"/>

<button id="button">button</button> <div id="dialog"></div> $('#button').on("click", function() { $('#dialog').load('/jsp/viewfolder/helloworldedit.jsp').dialog(); });

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.

http://localhost:port/.projectcontext/jsp/viewfolder/calendar.gif.

you have wait dom ready event:

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 } }
