    Posted: 06 October 2004 at 12:12pm

I need a reliable way to catch a message that a pane is being shown.  I have used code like this:

LRESULT CMainFrame::OnDockingPaneNotify(WPARAM wParam, LPARAM lParam)
{
 if (wParam == XTP_DPN_SHOWWINDOW)
 {
  CXTPDockingPane* pPane = (CXTPDockingPane*)lParam;
   ...my code here
 }
}

But this is not sufficient!  If my pane is hidden, I receive a XTP_DPN_SHOWWINDOW message more often than just when it is being shown, I also receive a XTP_DPN_SHOWWINDOW message for the pane when the pane is being hidden.

Where in my pane can I just catch that I am being shown?

Hi!

Did you find a solution to your problem? I have the same/similar problem: IŽd like to know when a user activates a pane by clicking on the tab to be able to update the contents if necessary. I get an ActivateView if the user clicks in the view, but not on the tab. Please let me know if someone knows how to do this.

Thanks.

LRESULT CMainFrame::OnDockingPaneNotify(WPARAM wParam, LPARAM lParam)
{
   if (XTP_DPN_ACTION == wParam)
   {
      XTP_DOCKINGPANE_ACTION* pAction = (XTP_DOCKINGPANE_ACTION*) lParam;
      ASSERT(NULL != pAction);

      if (xtpPaneActionExpanded == pAction->action)
      {
         // your code here   
      }
   }
}
