CMenu :: ModifyMenu的问题

Question

I'm using CMenu::ModifyMenu in the OnCreate method of my CFrameWnd derived class to change the captions on my menu to match the user language.

I'm using VC++ designer and the menu is declared in a .rc file.

For the MENUITEM elements I use it as follow:

m_wndMenu->ModifyMenu(ID_APP_EXIT, MF_BYCOMMAND, NULL, CString((LPWSTR) ID_APP_EXIT));

For the POPUP elements (that don't have an ID) I use it as follow:

m_wndMenu->ModifyMenu(0, MF_BYPOSITION | MF_STRING, NULL, CString((LPWSTR) ID_MENU_POPUP_FILE));

It works as expected to change the captions, but for the menu items that are initialy disabled when I change the caption they get enabled. How do I fix this?

Answer 1

You may have to explicitly disable the menu item and set tool tip text after a call to ModifyMenu . Using ModifyMenu will effectively destroy the previous menu item and create a new one. You are losing any settings and initialization from the resource file or otherwise that you had on the previous item or menu.

Answer 2

for such scenario, better to use EnableMenuItem function, like this m_wndMenu->EnableMenuItem(ID_APP_EXIT, MF_BYCOMMAND| MF_ENABLED);

this will work...
