i have program capture video camera. application in windows form , want use code wpf application not working. use handle capture image ueye camera. in windows form 

displayhandle = picturebox.handle

but when use handle in wpf not received video camera. in wpf use handle

hwndsource hwndsource = hwndsource.fromvisual(pbmainimage) hwndsource; displayhandle = hwndsource.handle;

but still not working it

both handle used after

initializecomponent(); 
private void onframeevent(object sender, eventargs e){   ueye.camera camera = sender ueye.camera;    int32 s32memid;   camera.memory.getactive(out s32memid);   camera.display.render(s32memid, displayhandle, ueye.defines.displayrendermode.fittowindow); }

displayhandle si handle component pictureimage.

thanks help.

 hwndsource hwndsource = hwndsource.fromvisual(pbmainimage) hwndsource; displayhandle = hwndsource.handle;

do not use after

initializecomponent();

because hwndsource null camera not recognize handle. can create handle before use handle not after initialize component.
