<P>It is possible to make the TrackPopupMenu method of CMenu return the value of 
the item that was selected rather than having to process the menu commands 
through the message map. This is possible using two undocumented flags 
TPM_NONOTIFY and TPM_RETURNCMD. As their names imply the first causes the menu 
not to send a command massage, and the second causes the method to return the ID 
of the command selected. If no command was selected the value returned is 0.</P>

<pre><tt><font COLOR="#990000">
CMenu menu;
int pMenuID = 0;
DWORD SelectionMade;
VERIFY(menu.LoadMenu(IDR_MENU1));

CMenu* pPopup = menu.GetSubMenu(pMenuID);
ASSERT(pPopup != NULL);

POINT pp;
GetCursorPos(&amp;pp);
SelectionMade = pPopup-&gt;TrackPopupMenu(
	TPM_LEFTALIGN | TPM_LEFTBUTTON |
	TPM_NONOTIFY | TPM_RETURNCMD,		 <strong>//**NOTE** Undocumented flags</strong>
	pp.x,pp.y,this);

pPopup-&gt;DestroyMenu();

//The value of SelectionMade is
//the id of the command selected
//or 0 if no selection was made

switch(SelectionMade)
{
	// ..... do something here .....
}
