SetParent Command1.hwnd, 0
SetWindowLong Command1.hwnd, -8, Me.hwnd
把command1分离窗口出来,使之能自由移动
对me做子类处理,捕获WM_MOVE消息,处理command1的位置需要注意的是如果希望command1响应事件,需要把它放在一个容器内
如frame1,然后对frame1使用上面的那两个函数。
可以参考
http://expert.csdn.net/Expert/FAQ/FAQ_Index.asp?id=7691下面是个简单的例子:
在窗体中放上一个frame,在frame中放上一个commandbutton

其实Winamp5用的标题栏是它自己的,所以可以,系统赋予窗体的就不太容易了

不是的呀只要打开着艾子哥呢,任何当前获得焦点的窗体的标题栏上都有的呀,那些可都不是艾子哥自己的窗体了
