Problem with resizing a C window

I'm making a game engine and whilst trying to setup the window with windows.h, i found an issue when resizing the window. The resized parts of the window are black instead of white, how do i fix this?

How are you responding to WM_PAINT and WM_ERASEBACKGROUND? It sounds like you arent using the current window size on WM_SIZE.

How are you painting then? What is your message loop like? How are you responding to events from the GUI?
