[python-win32] NEWBIE QUESTION - 'NoneType' object has no attribute 'ActiveSheet'

[Kenley _]

Thanks for the lucid response Tim. I nixed the import statements; however, 
Excel still only flashes on first click of the button.

The debug trace collector shows this on first click:
>>

OnStartupComplete None
pythoncom error: Python error invoking COM method.

Traceback (most recent call last):
  File "D:\Python23\Lib\site-packages\win32com\server\policy.py", line 283, 
in _Invoke_
    return self._invoke_(dispid, lcid, wFlags, args)
  File "D:\Python23\Lib\site-packages\win32com\server\policy.py", line 288,

    return S_OK, -1, self._invokeex_(dispid, lcid, wFlags, args, None, None)

line 71, in OnClick
    xlApp.ActiveWorkbook.ActiveSheet.Cells(1).Rows.EntireRow.Delete(1)
exceptions.AttributeError: 'NoneType' object has no attribute 'ActiveSheet'
<<

And then it runs correctly on second click:
>>

OnBeginShutdown None
OnDisconnection
OnBeginShutdown None
OnDisconnection

<<

My theory is that the object isn't loaded into memory yet on first click and 
only gets correctly instantiated AFTER the first click... Which allows it to 
work the second time around.

I have been trying to figure out how to preload the object into memory which 
is what caused my futile attempts with the import statement (Excel as 
xlApp). I've gone through Mark Hammond's book (and love it) but I'm just 
missing a key detail somewhere.

Thoughts?
