改变窗口控制的背景颜色和字体颜色

/* ColorControl.cpp coded by: Hound Example showing how to color listboxes, edits, radio/check boxes, and statics there is also a combobox in this example, they are a combinaton of an edit and a listbox window, hence the name combo.. NOTE: WM_CTLCOLORBTN does not work for pushbuttons only for radio/checkbox style buttons, to color a button you have to use an owner drawn button and handle ALL of the painting */ #include "ColorControls.h" LRESULT CALLBACK WndProc(HWND hWnd,UINT iMsg,WPARAM wParam,LPARAM lParam) { static COLORREF customcolors[16];
