散分！！！WinForm的菜单问题！！

可以先记下menu(类似于Windows的开始菜单的东西)弹出的位置，px,py。再根据鼠标右键单击的位置e.x和e.y计算菜单项的位置(e.x-px,e.y-py),再根据(e.x-px,e.y-py)确定是点击了那个菜单项,然后popmenu,

看看JAVASCRIPT的一个例子<html><head>

这个问题我记得在http://www.csdn.net/magazine中有看到过，很有意思啊，UPps:上面那个JS（网页）这么弱智有什么好贴的？

谢谢各位斑竹帮我置了顶！！！
Thank you!!!

你是要WinFOrm的还是WEB 的啊??

换个思维，我已前在Delphi中用窗口替代菜单，每一个用一个Panel，C#中没有试过。
这个可能有帮助：http://www.codeproject.com/cs/menu/vsnetmenu.asp
免费注册后，才能宰

小弟现在刚学C#，不会（希望大家能提供几本C#好书）
以前在VB里写过，用小窗体代替菜单，在窗体上用MSFlexGrid连着数据库（同时用了各种图标）

调试易

散分！！！WinForm的菜单问题！！
