I also created a feature class within the dataset. I tried to add another feature class, and it gave me the error: 'Cannot create a feature class..because the feature dataset is in use by another application/user' and Identifies MY machine as the user!??!??!!!?! </SPAN><BR /><SPAN>I can't delete the dataset or FC I created or paste a new FC to the dataset. </SPAN><BR /><BR /><SPAN>What's really bizzare is that I can create a new FC within the geodatabase ok, but NOT within the feature dataset! I've shut down/restarted etc, confirmed that no other users are in the GDB etc.</SPAN><BR /><BR /><SPAN>Does anyone have any ideas????</SPAN></BODY></HTML> Wed, 17 Apr 2013 16:44:55 GMT JamesHarrington 2013-04-17T16:44:55Z Cannot create Feature Class https://community.esri.com/t5/data-management-questions/cannot-create-feature-class/m-p/705387#M39969 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I just created a new feature dataset within a personal geodatabase.
