Create window with custom background color

[Unscruffed]

Hi guys, gals and inbetweens.

I'm working on a custom ComboBox.

This is what I'm doing...

I removed the border from the Listbox using GetWindowLong and SetWindowLong. Ok.

Using CreateWindowEx, create a window and place the listbox in it. All ok except the background color of the created window is ButtonFace. I need to change this, or draw a rectangle to simulate the custom border color.

I tried catching the WM_PAINT msg for the window, and tried FloodFill and Rectangle, but it draws over the listbox as well.

I know I'm missing something simple, but what?

Thanks,
Scruff.

Be good. If you can't, don't get caught!
