Disable right-click context nenu in a HTML dialog based application

Although there are many similar questions asked on EE I have scanned through many of them and haven’t found an answer to my question. I’ve made a dialog based wizard-style application which inherits from CmultiPageDHtmlDialog. I want to prevent the user from displaying the right-click context menu. The main reason is so that they don’t navigate without using by navigation buttons.

Any suggestions? Thanks!

You could override the 'OnRButtonDown()'  handler to do nothing...

And also prevent pressing *BACKSPACE*
For that you can filter these keypresses in the "PreTranslateMessage" function like

BOOL CmultiPageDHtmlDialogEx::PreTranslateMessage(MSG* pMsg)
{
      if ( pMsg->hwnd == m_hHTMLWnd &&
             pMsg->message == WM_KEYDOWN &&
             pMsg->wParam == VK_BACK )
      {
            return FALSE;
      }

      return CDialog::PreTranslateMessage(pMsg);
}

I have never used the CmultiPageDHtmlDialog so the following may not work.

In your dlg override the PreTranslateMessage fn.
then add
      if(pMsg->message == WM_RBUTTONDOWN)  //possibly also trap WM_RBUTTONUP
        return TRUE;
returning true tells the app it has been handled - so it is hopefully not passed on and generates the context menu

Thanks everyone for your contributions! Roshmon’s code worked perfectly except I don’t know what the equivalent of m_hHTMLWnd is in my app. Why do I need this line (pMsg->hwnd == m_hHTMLWnd) and how do I find the correct vairable name in my app?

Hopefully I'll share some points out this evening; I'm on dial-up at moment :(

Thanks!

The m_hHTMLWnd is the HWND of your dialog  (GetSafeHwnd() fn will return it)
