GDI Leak Problem

Question

I'm experiencing memory leaks while running the following GDI code:

HDC hdcScreen = GetDC(NULL);
HDC hdcMem = CreateCompatibleDC(hdcScreen); 
HBITMAP hbmpOld = (HBITMAP) SelectObject(hdcMem, hBmp); // apparently here is the leak 

// do something

SelectObject(hdcMem, hbmpOld); //placing the old object back. The return object is handled elseware
DeleteDC(hdcMem);  // after CreateCompatibleDC
ReleaseDC(NULL, hdcScreen); // after GetDC

I already looked at similar threads, such as this but I couldn't find the problem. Any help would be appreciated.

DeleteDC, ReleaseDC return value was checked to be true (no errors).

Thanks, Tal.

Answer 1

Solved. The problem was hBmp wasn't correctly initialized, so there was a crash at the SelectObject - no error, just the function exited, skipping the "//do something" and the releases part.
