Modify menuitems

[Quakey]

Hi there,
I wanted to modify the string of many menuitems on the fly. Here are the codes I used:
CMenu* hMenuCopy;
hMenuCopy=new CMenu;
hMenuCopy->LoadMenu(IDR_MENU_Display);
hMenuCopy->GetSubMenu(0)->GetSubMenu(7)->ModifyMenu(1,MF_STRING|MF_BYPOSITION,hMenuCopy->GetSubMenu(0)->GetSubMenu(7)->GetMenuItemID(1),Field1);

However, it doesn't work. Please tell me what's wrong. By the way, if I obtain the menu by using
GetMenu() rather than LoadMenu, those codes work. Why? Thanks in advance.

You are modifying the new menu fine, which doesn't mean that it is the displayed menu. Why don't you want to use GetMenu() ?

Anyway, if you want to replace the current menu with the one you modified, do like the following.

// First destroy the current menu
GetMenu()->DestroyMenu();

// Then set the current menu
SetMenu(newMenu);

Hi there,
Thanks for the answer, however, I guess I didn't state my question clearly.

The menu I wanted to modify isn't the mainframe menu. It's already created in the resource, and I call
them up by using LoadMenu and then call TrackPopupMenu when the user right-click the mouse. I
needed to modify the menuitem in that menu at startup of the program with the codes in my previous
message, and it didn't work. So my question should be: is the menu in the resource changed when I
attemp to modify it or I just can't modify it permanently so that's why even though I've modified the
items but then I load it it just loads the original one from the resouce? If that's case, does that mean I
should modify the menu just before the call to TrackPopupMenu? Thanks.

ModifyMenu modifies an item in a menu whatever it is loaded from a resource or created at runtime. It does not change the resource. I don,t know if there is a way to modify a resource at runtime.
