The simplest way to put the MRU list in a submenu

Environment: Tested on NT 4.0 SP3, VC6.0

Putting the MRU list in a submenu might appear just a matter to move the menu item ID_FILE_MRU_FILE1 from the 'File' menu to a submenu. Unfortunately a bug (of the CRecentFileList class I read but I believe that it's elsewhere in the framework) makes the things more complicated. As you can verify, even if it's unbelievable, the MRU list continues to appear in the main "File" menu! After some hours of deep desperation, I found a simple workaround. Once again, the solution came from an accurate analysis of the MFC code.

Using the ClassWizard, add the UPDATE_COMMAND_UI handler for the ID_FILE_MRU_FILE1 command to your application class and call it OnUpdateMruFile1. Then, just insert the following two lines of code:

void CMyApp::OnUpdateFileMruFile1(CCmdUI* pCmdUI) { 
	if (pCmdUI->m_nIndex == 0)
		OnUpdateRecentFileMenu(pCmdUI);
}

The OnUpdateRecentFileMenu() is the CWinApp own handler for ID_FILE_MRU_FILE1.

Note that the check:

	pCmdUI->m_nIndex == 0 

Relies on the fact that the ID_FILE_MRU_FILE1 item is the first item of its submenu. Therefore, the MRU list will never be updated if you insert some item before it.

I believe this be the simplest way to put the MRU list in a submenu.

    // TODO: Add your command update UI handler code here

    if (pCmdUI->m_nIndex == 0)
    OnUpdateRecentFileMenu(pCmdUI);
    }

    But I get this error:

    'OnUpdateRecentFileMenu' undeclared identifier.

    You've mentioned that this function is a CWinApp handler. I could not find it anywhere.
