Type.GetTypeFromProgID("esriDataSourcesOleDB.TextFileWorkspaceFactory") returns null

[AnatoliyZharkikh]

Hi, I just barely upgraded to 10.1 and I noticed a new problem that I can't figure out the solution to. My addin relies on being able to load in a csv file and the following line gives me null:

Type factoryType = Type.GetTypeFromProgID("esriDataSourcesOleDB.TextFileWorkspaceFactory");

This worked just fine in 10.0 and now I got holes in my program. Anyone know a workaround?

Thanks,
Toly

Why not use the actual type instead of looking it up via the ProgID:

http://edndoc.esri.com/arcobjects/9.2/NET/c68303f6-8360-40c0-9faa-e0efdcc44c86.htm

Just add a reference to ESRI.ArcGIS.DataSourcesOleDB.dll and then use the class.

With ArcGIS Server it's not possible to register OLE DB connections with the data store.  See here.  This might be the problem.  It would help if you explain more about what your add-in does in ArcMap and how it makes use of ArcGIS Server.

Toly,

TextFileWorkspaces changed slightly in the 10.1 release of ArcGIS, if you modify your code in this way it should work in 10.1.

Type factoryType = Type.GetTypeFromProgID("esriDataSourcesFile.TextFileWorkspaceFactory");

Hope this helps,

Brent,

Thanks for the hint. I just found this thread because I had the same issue. It would be helpful if the pages http://resources.arcgis.com/en/help/arcobjects-net/conceptualhelp/#/Interacting_with_singleton_objec... and http://resources.arcgis.com/en/help/arcobjects-net/conceptualhelp/index.html#//000100000408000000 reflected the change.

Cheers

I am doing this, but still having an issue opening my csv file. It doesn't really give me an error. Anyone run into this issue?

And I have tried it both ways (direct reference and by Type).
