Context Menu

[Harddisk]

Hi, I was learning this Context Menu example based on an e-book where I've been supplied with this code

 1: void CMenusDlg:: OnContextMenu(CWnd* pWnd, CPoint point) 
 2: {
 3:     // TODO: Add your message handler code here
 4:     
 5:     ///////////////////////
 6:     // MY CODE STARTS HERE
 7:     ///////////////////////
 8: 
 9:     // Declare local variables
10:     CMenu *m_lMenu;     // A pointer to the menu
11:     CPoint m_pPoint;    // A copy of the mouse position
12: 
13:     // Copy the mouse position to a local variable
14:     m_pPoint = point;
15:     // Convert the position to a screen position
16:     ClientToScreen(&m_pPoint);
17:     // Get a pointer to the window menu
18:     m_lMenu - GetMenu();
19:     // Get a pointer to the first submenu
20:     m_lMenu = m_lMenu->GetSubMenu(0);
21:     // Show the Popup Menu
22:     m_lMenu->TrackPopupMenu(TPM_CENTERALIGN + TPM_LEFTBUTTON,
23:         m_pPoint.x, m_pPoint.y, this, NULL);
24: 
25:     ///////////////////////
26:     // MY CODE ENDS HERE
27:     ///////////////////////

28: }

The compilation went smoothly except there are 2 warnings on line 18 and 20.

Nevertheless, the application runs, but when I do a right click on the form, it crashes.....

Any idea what's wrong with it?

Thanks for any help
