Getting CMenu * object for processing..

Hi,

I am using CJ menubar to show menus in my application..

Now, to get the menu pointers (to check-uncheck the menu items according to the state of the application,) i need to get the CMenu *.. now, following code is failing..

CMenu *m_mainMenu = m_wndMenuBar.GetMenu();
CMenu *m_fileMenu = m_mainMenu->GetSubMenu(1);
CMenu *m_toolMenu = m_mainMenu->GetSubMenu(1);
CMenu *m_themeMenu = m_toolMenu->GetSubMenu(0);

But ont the second line itslef the code crashes... Please tell me where i am wrong..
