简单来说，就是版本不同，只不过是升级后建议功能更加强大的ContextMenuStrip罢了，升级后的元件功能更强 。 ContextMenu是VS2005里的，而ContextMenuStrip是VS2008以后的版本里面的。 ContextMenuStrip 替换 ContextMenu， 【1】可以将 ContextMenuStrip 与任何控件关联，单击鼠标右键会自动显示快捷菜单。 【2】可以通过使用 Show 方法以编程方式显示 ContextMenuStrip。 【3】ContextMenuStrip 支持可取消的 Opening 和 Closing 事件以处理动态填充和多次单击方案。 【4】ContextMenuStrip 支持图像、菜单项复选状态、文本、访问键、快捷键和级联菜单。 尽管 ContextMenuStrip 对以前版本的 ContextMenu 控件的功能进行了替换和添加，但考虑到向后兼容性和将来的使用（如果的确需要），仍然保留了 ContextMenu。 建议采用ContextMenuStrip 来源： https://www.cnblogs.com/xixiuling/p/11993348.html

I'm having hard times figuring out why this doesn't work on my computer.

When an OpenLaszlo application is deployed using the SWF10/11 runtime, is it possible to completely disable the Flash Player context menu on desktop computers? That's only possible starting with Flash Player 11.2. I have done a test run with a modified version of OpenLaszlo based on the flex4.6 branch, adding Flash 11.2+ support to the OpenLaszlo compiler. With the following LZX code I managed to remove the default Flash Player context menu completely: <canvas width="100%" height="800" proxied="false"> <passthrough when="$as3"> import flash.events.MouseEvent; </passthrough> <handler name=

I want that when I click on a menu item, display a context menu with items such as "delete", "rename", etc. How to bind itself a context menu when you right-click on the menu item? The first idea jumping in my mind was hook up some MouseDown event on the ToolStripMenuItem and show the second ContextMenuStrip at the mouse position in screen coordinates. But it's not such simple.
