i try capture desktop screenshot using sharpdx. application able capture screenshot without labels in windows explorer. tryed 2 solutions without change. tried find in documentation information, without change.

here mi code:

        public void scr()     {         uint numadapter = 0; // # of graphics card adapter         uint numoutput = 0; // # of output device (i.e. monitor)          // create device , factory          var device = new sharpdx.direct3d11.device(sharpdx.direct3d.drivertype.hardware);         var factory = new factory1();          // creating cpu-accessible texture resource         var texdes = new sharpdx.direct3d11.texture2ddescription         {             cpuaccessflags = sharpdx.direct3d11.cpuaccessflags.read,             bindflags = sharpdx.direct3d11.bindflags.none,             format = format.b8g8r8a8_unorm,             height = factory.adapters1[numadapter].outputs[numoutput].description.desktopbounds.height,             width = factory.adapters1[numadapter].outputs[numoutput].description.desktopbounds.width,             optionflags = sharpdx.direct3d11.resourceoptionflags.none,             miplevels = 1,             arraysize = 1         };         texdes.sampledescription.count = 1;         texdes.sampledescription.quality = 0;         texdes.usage = sharpdx.direct3d11.resourceusage.staging;         var screentexture = new sharpdx.direct3d11.texture2d(device, texdes);          // duplicate output stuff         var output = new output1(factory.adapters1[numadapter].outputs[numoutput].nativepointer);         var duplicatedoutput = output.duplicateoutput(device);         sharpdx.dxgi.resource screenresource = null;         sharpdx.datastream datastream;         surface screensurface;         var = 0;          var miliseconds = 2500000;         while (true)         {             i++;             // try duplicated frame within given time             try             {                 sharpdx.dxgi.outputduplicateframeinformation duplicateframeinformation;                 duplicatedoutput.acquirenextframe(miliseconds, out duplicateframeinformation, out screenresource);             }             catch (sharpdx.sharpdxexception e)             {                 if (e.resultcode.code == sharpdx.dxgi.resultcode.waittimeout.result.code)                 {                     // has not been successful capture                     // @randy                      // keep retrying                     continue;                 }                 else                 {                     throw e;                 }             }              device.immediatecontext.copyresource(screenresource.queryinterface<sharpdx.direct3d11.resource>(), screentexture);             screensurface = screentexture.queryinterface<surface>();               //  screensurface.map(sharpdx.dxgi.mapflags.read, out datastream);              int width = output.description.desktopbounds.width;             int height = output.description.desktopbounds.height;             var boundsrect = new system.drawing.rectangle(0, 0, width, height);             var mapsource = device.immediatecontext.mapsubresource(screentexture, 0, mapmode.read, sharpdx.direct3d11.mapflags.none);             using (var bitmap = new system.drawing.bitmap(width, height, pixelformat.format32bppargb))             {                 // copy pixels screen capture texture gdi bitmap                 var bitmapdata = bitmap.lockbits(boundsrect, imagelockmode.writeonly, bitmap.pixelformat);                 var sourceptr = mapsource.datapointer;                 var destinationptr = bitmapdata.scan0;                 (int y = 0; y < height; y++)                 {                     // copy single line                      utilities.copymemory(destinationptr, sourceptr, width * 4);                      // advance pointers                     sourceptr = intptr.add(sourceptr, mapsource.rowpitch);                     destinationptr = intptr.add(destinationptr, bitmapdata.stride);                 }                  // release source , dest locks                 bitmap.unlockbits(bitmapdata);                  device.immediatecontext.unmapsubresource(screentexture, 0);                  bitmap.save(string.format(@"d:\scr\{0}.png", i));             }               //  var image = frombyte(tobyte(datastream));              //var image = getimagefromdxstream(1920, 1200, datastream);             //image.save(string.format(@"d:\scr\{0}.png", i));              // datastream.close();             //screensurface.unmap();             screensurface.dispose();             screenresource.dispose();             duplicatedoutput.releaseframe();         }     } 

after few hours of research , googling found working solution:

from:

pixelformat.format32bppargb 

to:

pixelformat.format32bpprgb
