Erase a window background?

[SFSxOI]

How do you erase a window background? (MSG_WM_ERASEBKGND)

[Sparkie]

Not sure what your needs are, but you can try

Code: Select all

RedrawWindow_(hwnd, #Null, #Null, #RDW_ERASE | RDW_INVALIDATE | #RDW_UPDATENOW)

InvalidateRect_() erases a window or the whole desktop, sending a #WM_PAINT message to an ereased window.

ValidateRect_() sends #WM_ERASEBKGND and #WM_NCPAINT to the window. But I don't know what this function does, because I#ve never used it yet.

For further information, please, have a look at the MSDN.
