在WiX MSI安装程序中注册上下文菜单

Question

I want to create a context menu something like the menu in 7-Zip using C#. How can I register the dll using WiX?

Answer 1

Step one is to learn how to do it by hand. This involves creating a Shell Extension, and registering it . Per MSDN, you do this by implementing IContextMenu and listing its CLSID in a subkey of the registry key HKEY_CLASSES_ROOT\\ ProgID \\ShellEx\\ContextMenuHandlers. Additionally, after writing that registry key, you have to call SHChangeNotify with SHCNE_ASSOCCHANGED , or reboot.

If your needs are simpler than the 7-zip case, you can likely just register a Verb or File Association instead.

Once you've done this, and tested it on your development machine, you're ready for step 2: make it part of your installer. If you're creating a verb or file association, that's possible with native Windows Installer tables, as exposed through the ProgId , Extension , and Verb elements. If you're registering a shell extension, I believe you have to create the registry keys directly through the RegistryKey and RegistryValue elements.
