菜单自绘加图标怎么实现

菜单自绘加图标如何实现？
rt

------解决方案--------------------
参考：http://www.copathway.com/vchelp/source/submit/rcoolmenu.zip
另外www.codeguru.com的menu的链接中有有源码。

这个的原理就是利用BitBlt在DrawItem中
将竖着的位图传送到菜单项中，
其实VC中的菜单上加图标也是这么做的，
比如使用工具栏的位图，用BitBlt传到菜单项上，
只不过这个要求你位图和菜单项大小要恰好合适，否则就对偏了。
------解决方案--------------------
自绘例子，修改一下就可以了
