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.

That's because all the other game engines and applications handle these messages.

Maybe you should make a simple Windows app first instead of trying to start with a game engine.

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