Quote:Original post by ReeganWhy? It doesn't say that anywhere in the documentation that I'm aware of. It's that reason that I always get the client area size by subtracting the left and top sides of the client area.
rcClient.left is always 0 same goes for rcClient.top (or rather, it should always be 0)
Just because GetClientRect() returns coordinates based at (0, 0) doesn't mean that all Win32 functions should.
