blit and BufferedPaintDC

[Declan McMullen]

Is it possible to use blit with a double buffered paint dc ?I have the
following function


wxBitmap WorkspaceView::getScreenShot(wxDC& dc)

{

wxSize screenSize =3D dc.GetSize();

wxBitmap screenBitmap(screenSize.GetWidth(), screenSize.GetHeight());

wxMemoryDC memDC;

memDC.SelectObject(screenBitmap);

memDC.Blit(0, 0, screenSize.GetWidth(), screenSize.GetHeight(), &dc, 0, 0);

memDC.SelectObject(wxNullBitmap);

return screenBitmap;

}



What I wanted to do with it was make a bitmap I could use for printing, i.e
just put everything

thats on the screen into a bitmap, send that image to my printout object and
print it.

All I'm getting though is a completely black image and I'm thinking its due
to my double buffering ?


Is it possible for me to get the contents of the buffer itself and use that
?
