| Okay...
hWnd literally means "handle to a window". Window can be a form (to use the less ambigious VB name), a control, your desktop... hDC literally means "handle to a device context", alternatively I'd call em "drawing canvases". Each window has a canvas. These are seperate entities. Each window class also knows how to draw itself, hence the whole "subclass a ComboBox to make it draw in the latest Office fashion" thing. BitBlt requires two canvases: the source and the destination. Creating a window returns the new window's hWnd. You can then call GetWindowDC(hWnd) to retrieve the matching canvas handle, which can then be used by your favorite graphics functions, including but not limited to BitBlt. Need more info? |

| I found my problem, GetLastError(); is one good function turns out my code was working but my location to the picture was wrong. Slap me. |
