click on a polygon and drop a number in the designated field in sequence

[rao_muhammadimranulhaq]

'm looking for a tool out there for sequential auto-numbering... something that uses the edit tool (or something similar) to simply click on a polygon and drop a number in the designated field in sequence, and it would obviously have to be easy to reset as the edit session progresses.

sounds pretty specialized and maybe an arcobjects task.

you could have a look at 

ArcGIS Code Sharing 

but I suspect you will have to implement your own
