screenshot - Screen Capture Complications with WPF window on top -

-

i need capture entire screen transparent wpf window topmost window. tried 2 approaches:

  1. using system.windows.drawing.graphics.copyfromscreen
  2. using winapi getdesktopwindow

both methods yield same result. entire screen except topmost transparent wpf window. wpf window w created with:

w.allowstransparency = true; w.windowstyle = system.windows.windowstyle.none; w.background = new solidcolorbrush( color.fromargb( 1, 0, 0, 0 ) ); w.topmost = true;

plus content of course. window covers entire screen surface.

apparently, wpf window draws on surface not included in getdesktopwindow.

can pls shed light on , share ideas how entire screen surface?

just found solution:

as far can tell there no solution graphics.copyfromscreen approach because you'd need or copypixeloperation.captureblt copypixeloperation.sourcecopy can't. usual m$ inconsistency madness...

however, winapi approach works since can combine srccopy , captureblt when using bitblt. without captureblt transparent , layered windows not included.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
