IContextMenu InvokeCommand

[Lars Nielsen]

I have made a shell extension dll in c# to add a menuitem to the explorer context menu

I have implemented these method
IShellExtInit.I nitializ
IContextMenu.Qu eryContextMen
IContextMenu.Ge tCommandStrin
IContextMenu.In vokeComman

When I register the dll with regasm and gacutil a menuitem shows in the explorer contextmenu and
IShellExtInit.I nitialize and IContextMenu.Qu eryContextMenu gets called. But GetCommandStrin g and
InvokeCommand never gets called when I click the menu item

Can anyone explain whats going on

Thank
Lars
