that effect in vb.you can see background not purely transparent .its translucent afaik.

i give ideas: can set backcolor , transparencykey color properties of form same color. assign transparent image want, through handling mybase.paint event, in way:

private sub frmlogin_paint(byval sender object, byval e system.windows.forms.painteventargs) handles mybase.paint if not me.cobjimagen nil e.graphics.drawimage(me.cobjimagen, 0, 0, me.width, me.height) end if end sub

where 'cobjimagen' system.drawing.image loaded 'form_load' event, or ' public sub new() ', example...

if need move form, help process messages correctly:

private const wm_nchittest integer = 132 private const htcaption integer = 2 protected overloads overrides sub wndproc(byref m message) if m.msg = wm_nchittest m.result = new intptr(htcaption) else mybase.wndproc(m) end if end sub

vb.net forms osx
