[python-win32] Problem with COM and MsExcel

[Brunain Christophe]

Hello all !

I begin tu use python win and the COM features

I try to do a little scripyt that takes a text file (an unload from a
database) and to put it in an excel worksheet

It works good, but only one time

the second time I execute the script, i only se the menubar and the =
toolbar
on the top of the screen, the document itself is not displaying

I see only what was my screen before the execution of the script

If i close all the excel sheets and look in the task manager, I see an
EXCEL.EXE still running

If i make an "end process" it works, but if i try to run the script =
once
again, it makes an error.

here is the script i use

import win32com.client

ex =3D win32com.client.Dispatch("Excel.Application")
ex.Visible =3D 1
ex.Workbooks.Open("C:\\test\\test.xls")
ex.Run("SaveText","C:\\test\\codes", "C:\\test\\codes2.xls")
ex.Quit

and the traceback i got when i close the excel.exe and run the script =
once
again
