[python-win32] Grabbing an active Excel application

[Blair Hall]

Further to my posting yesterday, and Jens' suggestion, I find that 'grabbing'
an existing Excel is still problematic.

Here is __init__ from my class that wants to use Excel

     def __init__(self
          ,   visible=1
         ):
         """
         Create a new file in the current working directory
         and save a new Excel workbook in it.
         """
         try:
             self.__app = win32com.client.Dispatch("Excel.Application")
             self.__app.Visible = visible
         except pythoncom.com_error, e:
             self.__comExceptionHandler(e)

When I instantiate that class the first time, then all
is fine. ie:

 >>> xl = myClass()

However, if I then immediately do something silly like

 >>> xl = myClass()

Excel disappears from view (it is still running though). From that point
on Python and Excel don't seem to be quite able to agree on how
to interact.

It seems that Jens' suggestion is fine, but in case I am looking for
a few more idiot-proof safeguards.

By the way, I am working on Win95.
