Hi everybody, I am testing on validating topology using python.The situation is when I run the script when arcmap is open, an error occurs which indicates the topology has already been opened (FDO error: -2147214980 Cannot acquire a schema lock because of an existing lock), but when I close arcmap,the error disappear and it works properly. Does it means I can't validate a topology when arcmap is open? If can, how can I make it. Thanks in advance.
You need to run the script 'in process' from ArcMap. If you have the script attached to a tool, make sure that the option in the tool dialog option 'Always run in foreground' is ticked. Then run the tool from the Catalog window in ArcMap.
