How to hide context menu item by using IExplorerCommand

Jojo Tang 86

I am inherit IExplorerCommand, IInitializeCommand, IObjectWithSite, IObjectWithSelection interface to show context menu item.
I want to hide registered context menu item by using GetState return ECS_HIDDEN, but it does not work??

IFACEMETHODIMP GetState(IShellItemArray * psiItemArray, BOOL fOkToBeSlow, EXPCMDSTATE *pCmdState)
{
*pCmdState = ECS_HIDDEN;
return S_OK;
}

Hello @Jojo Tang , based on the document of IExplorerCommandState::GetState, this API doesn't have function of hiding the context menu item, it is used to query the state of the menu item. You can refer to "Suppressing Verbs and Controlling Visibility" for how to achieve the purpose via policy settings. If you want to do it in runtime (programmatically), could you share more detailed information like which kind of context menu item do you want to hide? Do you want to hide a context menu for a file or a folder or desktop?

I can got selected files using IFACEMETHODIMP IObjectWithSelection::SetSelection(IShellItemArray *psia) and after getting selections items to decide hide/show context menu. How can i do?

For example, one drive show it's context menu when selecting files in onedrive sync folder

Not show context menu item when selecting files not in onedrive folder

The official sample CloudMirror works for me to hide the context menu item ( TestCommand ) using ECS_HIDDEN. Could you have a try? For troubleshooting the issue specific to your code sample, you can check whether the GetState() function get called? And does it work without IObjectWithSelection implemented?

I can reproduce this issue using ExplorerCommandVerb sample. I notice that even if I chane the GetState's body to the following, the behavior doesn't change at all. Althought it has a delay and displayed. So it seems previous installed DLL is actually used and new change is not applied. I'll do a further investigation on this and update to you if there is any progress.

*pCmdState = ECS_HIDDEN; return S_OK;

Hello @Jojo Tang ,

The shell treats ECS_HIDDEN the same as ECS_DISABLED for context menu items added via IExplorerCommand, where the menu item is disabled. An alternate approach is to implement a context menu handler, where the shell extension can decide whether to add an item to the menu in IContextMenu::QueryContextMenu.

Thank you!
