In which class do you handle ID_VIEW_PLOT? Don't use CMyWinApp but
CMainFrame. Then you can switch to the actual child window the following
way:

Mainfrm.cpp:

ON_COMMAND(ID_VIEW_PLOT, OnMenuViewPlot)

void CMainFrame::OnMenuViewPlot()
{
      CMyChildView* pView = NULL;
      CMyChildDoc* pDoc = NULL;

      CChildFrame* pChild = (CChildFrame*)MDIGetActive();
      if (pChild) pView = (CMyChildView*)pChild->GetActiveView();
      if (pView) pDoc = pView->GetDocument();

      if (!pDoc) return; // not found?!

      // With these pointers you can handle your drawing. For example:

      pView->SendMessage(WM_PAINT);

}

Can I ask for some more help? I have used ur way and its working fine.
But i still have a little problem. I will explain to you my situation
and please let me knoe if you can help.
I have an MDI App. I have a doc and view opened displaying some data.
Now in my menu I have a View->Plot item (ID_VIEW_PLOT) clicking on
which a new window (popup) will open on which I can display a graph.
To display a graph i need a CFormView derived view window which gets
displayed on clicking View->Plot. Can u detail me out how i can do
this. I need to have the handler for ID_VIEW_PLOT in CFormView derived
class and not in CWinApp class. With your previous solution I am able
to create new windows. But now i want 2 type of view classes wherein
the form view opens only if i click the menu item.
Thanx in advance.
