Hi all,
I created an MDI application and I want to show a tooltip containing document path when I move cursor on the relative tab (the same behaviour of Visual Studio).
I found this article:

How to obtain the absolute path of the tab(ToolTip) for mouse .[^]

but I cannot get path (or name) of the document. CMFCBaseTabCtrl struct contains a lot of informations such as tab index, but I cannot use this value to loop on open documents if I allow tab swapping or if I divide the View in two or more parts dragging and dropping a tab in the View.

Could you somebody please help me?

Thanks a lot

Please extend the parent of your tab :) :

1. Its message map:

2. Its function:
LRESULT CYourFrame::OnTabToolTipNeeded(WPARAM wParam, LPARAM lParam)
  if (m_cTabCtrl.GetSafeHwnd()) {
    CMFCTabToolTipInfo* pcInfo = (CMFCTabToolTipInfo*) lParam;
    if (pcInfo) {
      CString cszText;
      if (m_cTabCtrl.GetTabLabel(pcInfo->m_nTabIndex, cszText) &&
          cszText.GetLength()) {
        CYourView* pcView(DYNAMIC_DOWNCAST(CYourView, m_cTabCtrl.GetTabWnd(pcInfo->m_nTabIndex)));
        if (pcView->GetSafeHwnd()) {
          cszText += _T(" [");
          cszText += pcView->GetPath();
          cszText += _T("]");
        pcInfo->m_strText = cszText;
  return 0;
