MFC: disable New File and Save File features in SDI application

Question

What would be the easiest way of using commands in the code to programatically disable these two features in an application? Thanks in advance.

Answer 1

Call CMenu::EnableMenuItem with the appropriate menu items and MF_DISABLED as the second parameter. Here's the documentation.

Answer 2

You could handle the update UI message:

ON_UPDATE_COMMAND_UI(ID_FILE_NEW, OnUpdateFileNew)
ON_UPDATE_COMMAND_UI(ID_FILE_SAVE, OnUpdateFileSave)

...

void CMainFrame::OnUpdateFileNew(CCmdUI *pCmdUI)
{
    pCmdUI->Enable( FALSE );
}

void CMainFrame::OnUpdateFileSave(CCmdUI *pCmdUI)
{
    pCmdUI->Enable( FALSE );
}
