I am using VC++6.0, Created a SDI App based on CHTMLVIEW


I tryed the following

void CMyBrowserView::OnContextMenu(CWnd* pWnd, CPoint point)
{
     CMenu Menu;

     // Get a pointer to the menu
     Menu.LoadMenu(IDR_CONTEXTMENU);
     
     CMenu *mMenu;
     // Get a pointer to the submenu
     mMenu = Menu.GetSubMenu(0);
     // Open it as a context menu
     mMenu->TrackPopupMenu(TPM_LEFTALIGN + TPM_LEFTBUTTON,
          point.x, point.y, pWnd, NULL);    
}

and

void CMainFrame::OnContextMenu(CWnd* pWnd, CPoint point)
{
     CMenu Menu;

     // Get a pointer to the menu
     Menu.LoadMenu(IDR_CONTEXTMENU);
     
     CMenu *mMenu;
     // Get a pointer to the submenu
     mMenu = Menu.GetSubMenu(0);
     // Open it as a context menu
     mMenu->TrackPopupMenu(TPM_LEFTALIGN + TPM_LEFTBUTTON,
          point.x, point.y, pWnd, NULL);          
}

and still it didn't popup my contextmenu. Any Ideas on how to fix that?

TPM_LEFTALIGN + TPM_LEFTBUTTON

should be

TPM_LEFTALIGN | TPM_LEFTBUTTON

But I don't think this is the only problem.

General tip:  First step in diagnosing a problem like this is to see if your message handkler is being called.  Place something like this

   MessageBox("OnContextMenu called!");
at the top of the function.  I'll wait...

So now, you know that your handler is not being called.  That is because the Webbrowser intercepts all clicks made in it.  Creating a custom context-menu handler for a WebBrowser controls is quite tricky.  The steps are described here:

http://207.46.197.63/gomsuri.asp?n=1&c=rp_Results&target=http://support.microsoft.com/support/kb/articles/Q236/3/12.ASP

It tells how to disable it, but at the same location on the code where they disable it, you can pop up a menu of your own.


Incidently, if you simply want to disable the contxt menu, there is an easier way.  Override PreTranslateMessage and use code like this  

BOOL CSdiHtmlView::PreTranslateMessage(MSG* pMsg)
{
     if (pMsg->message == WM_RBUTTONDOWN) {
          MessageBox("Please don't press that button any more!");
          return 1;
     }
     
     return CHtmlView::PreTranslateMessage(pMsg);
}

MarkOttoSmith has not responded to my request of 4/27/02, nor to help posted by Experts.  It looks like this is left in my hands to finalize.

Expert input is appreciated here so I can be fair in the finalization of this question.

Thanks,

Moondancer,
Although I billed my comment as a 'general tip' it also included a complete and specific solution to the problem.  I submit that unless MarkOttoSmith requests clarification, I desrve credit for that answer.
