What is the best way to execute custom code when a version is posted to DEFAULT?

JordanParmer — Mon, 25 Oct 2010 17:45:38 GMT

I need to write custom code that compares versions on 'Post'. I want to compare the edit version being posted to the DEFAULT version prior to the actual edits being committed in DEFAULT.

I've thought of writing a custom Post command for ArcMap, but this requires all of our GIS analysts to have the extension installed (and use it). That is too much of a training risk.

It would be ideal if I could catch the Post at the database level so that no matter who posts, I can handle the event.

Any ideas on how I might do that (or something similar)?

Hi Jordan,

One option would be to create a workspace extension that implements the IVersionEvents2 interface. The major drawback of this is that you'd still have to deploy a DLL to all of your users, but it has the advantage over a custom command that your users can still rely on the standard post command. Once they install the DLL the user experience won't change for them at all.

Here's a link with more information: http://help.arcgis.com/en/sdk/10.0/arcobjects_net/conceptualhelp/index.html#/Creating_workspace_extensions/000100000423000000/

Hey James,

That is a good idea. I've been looking into it. Unfortunately, the way our company is structured, our GIS analysts are somewhat sandboxed from our development group. There is a likely chance that a new employee will get a machine pre-loaded with a GIS image without our extensions installed.

After thinking on this, I think I'm going to have the GIS analysts post all of their edits to a QA/QC version and then write a custom process that posts that version to DEFAULT allowing me to run custom code comparing the two versions.

Is there a way to prevent people from posting to DEFAULT?

I think setting your DEFAULT version's permissions to Protected should give you what you're looking for.

Cheers,

Thanks James! I'll look into that.
