I created a toolbar within OnCreate in
mainframe.cpp.The toolbar is initially hidden.
I need to show the toolbar from within view.cpp
when a certain condition is true.
I have tried several approaches with no luck.

Here is sample code which will you idea on how to do it.
Create the tool bar in Frame class, set its styles, make it visible. Since you want to hide it intiallly, therefor before exiting the CMainFrame::OnCreate function hide the tool bar like this

ShowControlBar (&m_wndShapeToolBar, FALSE, FALSE);

And then in the view class, you can grab the frame to which this tool bar is attached. From the frame, get the pointer to the tool bar. And then call ShowToolBar. This sample function keeps flipping the visibility of tool bar. Like if its visible, then make it invisible or the other way round.
I was doing this test in my OnSetCursor function of my view class.

The way i have shown is just to give you idea. I am sure you can write a better efficient function.

BOOL CGridView::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
      if (m_bOnXSection) {
            SetCursor (m_hIntersectionCursor);
            CWnd *pWnd = AfxGetMainWnd ();
            CFrameWnd *pFrame = static_cast<CFrameWnd *>(pWnd);
            CFrameWnd *pMainFrame = pFrame->GetActiveFrame ();
            CControlBar *pBar = pMainFrame->GetControlBar (ID_VIEW_SHAPE_TOOLBAR);
            if (pBar != NULL) {
                  bool isVisible = ((pBar->GetStyle () & WS_VISIBLE) != 0);
                  pMainFrame->ShowControlBar (pBar, !isVisible, FALSE);
            }
            return TRUE;
      }

      return CView::OnSetCursor(pWnd, nHitTest, message);
}
      }

I didn't know about the ShowControlBar func.
That was what I needed.
m_bar.ShowWindow(SW_SHOW) wouldn't work!
Thanks..
