Disable Menu?

How do I disable and enable a menu item in an MFC Program?

In your message map, add an ON_UPDATE_COMMAND_UI macro such as the following:

ON_UPDATE_COMMAND_UI(ID_FILE_OPEN, OnUpdateFileOpen)

In your header file, declare the function like:
afx_msg void OnUpdateFileOpen(CCmdUI* pCmdUI);

Then in the actual function body, all you really need to do is to call the Enable function of CCmdUI:

void CMainFrame::OnUpdateFileOpen( CCmdUI* pCmdUI )
{
// assume m_bEnableMenu is a member of CMainFrame
pCmdUI->Enable( m_bEnableMenu );
}
