Vadim was refering to the UpdateWindow function in the win32 api, effectivly
bypassing wxPython.  You can get the window's HWND by calling it's GetHandle
method.  So something like this:

    import win32gui
    win32gui.UpdateWindow(window.GetHandle())

I've looked too.  None of the CoClass classes in the Excel type library will
instantiate as an ActiveX class.  I seem to remember seeing something in
MSDN about MS Office OLE needing contianer objects to implement IViewObject,
or something like that.  Maybe that's the problem...

There is a ray of hope however.  The WebBrowser ActiveX object (internet
explorer) can view excel workbooks just fine.  In the wxPython demo for
ActiveXWrapper_IE type the path of a .xls file into the combo box and it
should load it up fine.  I didn't look any further to see what else you
could do with it once it is there...  Perhaps this will be enough for your
app?
