Dynamically change a menu label

I am trying to change a menu item label text dynamically in reponse to a
menu
command. Here is the code that does not work, what could be my problem?

void CMainFrame::OnUpdateTrayHide(CCmdUI* pCmdUI)
{
CString HideShow;

if (m_AppInTray == false)
{
HideShow = _T("Hide");
}
else if(m_AppInTray == true)
{
HideShow = _T("Show");
}

pCmdUI->SetText(HideShow);
MessageBox(HideShow); // this updates correctly so I know the string is
changing

}

Everything seems OK. Is it possible that this update is being done some
other place too and maybe thats overriding this?

Dynamically change a menu label

This was the bug:
The following was in my OnTrayNotification method, so i commented them out
and it works.
(TPM_LEFTALIGN | TPM_LEFTBUTTON /*| TPM_NONOTIFY | TPM_RETURNCMD*/)
