Hi,

Give this a shot in your OnInitDialog or OnInitialUpdate method:

=================================================================================

CMenu* systemMenu = GetSystemMenu(FALSE);

if(systemMenu)
{
      systemMenu->EnableMenuItem(SC_CLOSE, MF_BYCOMMAND | MF_DISABLED);
}

=================================================================================

I hope that helps.

Hi,

Sorry about that.  Instead of adding that code to OnInitialUpdate, add it to CMainFrame::OnCreate().  Also, instead of MF_BYCOMMAND | MF_DISABLED for the second parameter in EnableMenuItem, change it to MF_BYCOMMAND | MF_GRAYED | MF_DISABLED.  This will gray out and disable the option to close from the taskbar as well.

I hope that helps.

My solution is:

//add this at

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{

     CMenu *pmenu = GetSystemMenu(FALSE);
     pmenu->EnableMenuItem(SC_CLOSE, MF_BYCOMMAND | MF_DISABLED|MF_GRAYED);
}


It can work...anywhere thanks!
