you respond to it in wndproc of the parent window.

in your wm_ctlcoloredit handler, you can use the HDC that''s in wParam to change background color and font for the edit control that sent you the message.

no.

write a handler for wm_ctlcoloredit in your main wndproc.

call setbkcolor there using (HDC) wParam as the device context.

LRESULT CALLBACK WndProc (HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
.....
case WM_CTLCOLOREDIT:
SetBkColor((HDC)wParam, RGB(0,255,0));
break;
....
}


Is that right ?
