My menu is the MainFrame menu in MDI application. In first position I have
"File" and above like following:

File

New>>> Document

File

Open
Exit

In this case all positions have ID, less "New", that is a popup menu.
Because don't have ID cannot be renamed using MF_STRING.

You create it at the point where you know what you want to change. Presumably you have a
reason for changing this on-the-fly, as opposed to simply changing the menu in the
resources. So it depends on whether this is a global change, a change depending on the
document, or change depending on the view. Note that if you put it in the mainframe,
there may be a need to modify other handlers.

It is ALWAYS the case that the menu in MDI will be reset; that's why you have to do it in
OnInitPopup and OnUpdateCommandUI events, because the menu can change at any time,
arbitrarily, when a document is created, when a view changes, etc. Note that I use the ID
for the SUBMENU to identify which menu is being popped up. So if you want to modfiy the
File menu, you have to know you are *in* the File menu, and the only way to find that out
is by asking if the popup has, for example, ID_FILE_OPEN. Then you know that the index
value is the index of the File menu *in the current instantaneous configuration* of the
menu.

Here you create OnInitMenuPopup? In CMainframe?
You are getting state with ID, but popup menu don't have ID.
My aplication is an MDI, and when I open or close a view the menu text
reback to the initial text. How can I avoid this?
Tks.

I want modify the text in a popupmenu in my mainframe menus.

I have the following sample.

File

               > File
  >Open

All items are easy to change text because they have an ID. To change ???File???
and ???Open???:

CMenu* lcl_menu = AfxGetMainWnd()->GetMenu();

Stop right here. This is where you are immediately going wrong. You will need to add an
OnInitMenuPopup handler, and update the menu at that point.

lcl_menu->ModifyMenu( 0, MF_BYPOSITION, 0, ???FileX???);

This is only safe it is SDI. If it is MDI, the menu will start at offset 1. Whenever you
are using MF_BYPOSITION, you must first compute the menu item you wish to modify and only
THEN can you modify it. Fortunately, this is already done for you.

void CMyClass::OnInitMenuPopup(CMenu * popup, UINT index, BOOL bSysMenu)
{
if(!bSysMenu)
    {
     UINT state = popup->GetMenuState(ID_FILE_OPEN);
     if(state != (UINT)-1)
         {
          popup->ModifyMenu(index, MF_BYPOSITION, 0, _T("&FileX"));
          AfxGetMainWnd()->DrawMenuBar();
         }
     }
   CParentOfMyClass::OnInitMenuPopup(popup, index, bSysMenu);
*****

lcl_menu->ModifyMenu( ID_OPEN, MF_STRING, ID_OPEN, ???OpenX???

*****
This needs to be done elsewhere. Add an OnUpdateCommandUI handler:

void CMyClass::OnUpdateOpen(CCmdUI * pCmdUI)
    {
     pCmdUI->SetText(_T("&OpenX"));
    }

Note that you should NOT hardwire these strings, but they should be loaded from the
STRINGTABLE, or you will have trouble localizing the app. Don't forget the _T() around
all the literal strings. 8-bit strings are rather quaint.
****

AfxGetMainWnd()->DrawMenuBar();

How can I change ???New????

****
The same was as shown for Open

Thanks.
