It is CommandType.Text, but that doens't work. Same error. I should have said I tried that. Have you been able to execute a VFP stored procedure from C#?

FWIW, it also doesn't work to set CommandType to 8 (unknown). That results in a build error.

Also should have said vfpoledb.dll version 7.0.0.9262
