I want to disable items on a popup menu and CExtPopupMenuWnd::EnableMenuItem() is udefined.
I’m using: dwTrackFlags = TPMX_DO_MESSAGE_LOOP | TPMX_NO_WM_COMMAND | TPMX_NO_CMD_UI; so I’m not doing any menu message handling in the parent window.
I can use ItemRemove() but that’s not what I want.

Dear Neville,
This task can be done via CExtPopupMenuWnd::MENUITEMDATA type.
1) Get the menu item data for some item:
CExtPopupMenuWnd::MENUITEMDATA & _md = pPopup->ItemGetInfo( nItemIndex );
2) Enable or disable it:
_md.Enable( false or true );

Thanks. ItemGetInfo() isn’t in the help. :(
It would nice to have the standard CMenu functions like this available as CExtPopupMenuWnd member functions.

Dear Neville,
The CExtPopupMenuWnd class provides a set of features that are not available in the standard HMENU of Win32 API: color submenus, built-in text fields and combo fields (coming soon), and command delivery for a specified window. In most cases LoadMenu() is enough. When a menu is loading, only its command ID’s and submenu structure are analyzed. At this moment, text and icon properties should be already registered in the command manager. In other words, a popup menu is designed to work with the command collection in the command manager. That is why we did not make it absolutely similar to the Win32 HMENU.
We are rewriting the documentation for CExtPopupMenuWnd class right now. It should cover all the methods and features.
