Question

I am getting a DC for a window handle of an object in another program using win32gui.GetDC which returns an int/long. I need to blit this DC into a memory DC in python. The only thing I can’t figure out how to do is get a wxDC derived object from the int/long that win32gui returns. None of the wxDC objects allow me to pass an actual DC handle to them from what I can tell. This of course keeps me from doing my blit. Is there any way to do this?

I downloaded the wxWidgets source and dug around, and I think this will work.

You need the handle (HWND) for the external window, not the DC.

window = wx.Frame(None, -1, '')
window.AssociateHandle(hwnd)
dc = wx.WindowDC(window)
