UpdateCursor.Reset() method not working.

NeilOllerhead — Mon, 28 Feb 2011 15:27:57 GMT

I am trying to use the .Reset() method to re-iterate through a list of records in a featureclass but it isn't working. The first loop executes perfectly but when it gets to the second loop it doesn't start...the 'row' object is 'None'.

I have done a bunch of searches trying to see if I am calling the reset method incorrectly but it appears as everything is fine. Any help or suggestions would be appreciated.

-----------------
rows = gp.UpdateCursor(lyrInput,'','','','FIRST_ A')
row = rows.next()

while row:
### do something

rows.reset()
row = rows.next()
while row:
### do something else

The training course notes suggest that all the Reset methods are to be implemented "in the future".
Meanwhile you have to close the cursor and reopen it to get the equivalent.

It's been in the documentation as far back as 2005 and has never worked! :mad:

I agree the documentation could be more clear. It does state, or rather omits, that reset() is not a supported method here, under "The Cursor Object".
