Hi, Einar-

>I have a program using some VFP 2.6 tables to maintain compatiblility with Clipper. I need to use a UDF to do indexing to get the right collation. In the progress to move to .Net I need the same user defined function in VFPOLEDB. Is it possible? (Index on UDF(string))

According to the Help file, INDEX ON is a supported VFPOLEDB function, so I'd say it's worth a trying. It should be relatively easy to test and then make sure you can still access the table and index as needed.
