How do you programatically switch versions on the parcel fabric?

KennethDinsmore

I have a .net add-in for ArcGIS Desktop that helps a user set up their map document when they are starting a new project. One of the tasks that this add-in does for the user is create a version for the project (if it doesn't already exist) then switch all of the versioned layers to use that version. This works perfectly for "normal" feature classes, tables, relations etc. But it doesn't work for Parcel Fabric datasets. I haven't found any sample code that addresses this issue, does anyone have a sample that does this?

Resolved, this is clean and simple and maybe this will save someone else some time. This will change the version for all of the feature classes that are in the workspace of OldVersion. Thanks to the guy at ESRI who shared this with me.

private void ChangeDBVersionForDocument(IVersion OldVersion, IVersion NewVersion)
{
IActiveView pActiveView = ArcMap.Document.ActiveView;
IMap pMap = pActiveView.FocusMap;
IBasicMap pBasicMap = (IBasicMap)pMap;

if (OldVersion == null || NewVersion == null)
return;

IChangeDatabaseVersion pChDBVer = new ChangeDatabaseVersionClass();
pChDBVer.Execute(OldVersion, NewVersion, pBasicMap);
System.Runtime.InteropServices.Marshal.ReleaseComObject(pChDBVer);

//notify listeners that the event was fired
IMapAdmin2 pMapAdmin = (IMapAdmin2)pMap;
pMapAdmin.FireChangeVersion(OldVersion, NewVersion);
}
