Hi,
This problem might be with fdo3.3.1.
previously it works fine for fdo3.3.0 oracle providers
Dim byteReader As MgByteReader =featureReader.GetGeometry("GEOMETRY")
but i have replaced this fdo3.3.0 with fdo 3.3.1 oracle providers( 3 dlls
) for IN operator in setfilter .
while executing above statement i got an error that
"Specified object was not found"
Can any one plz tell me the solution???????
Regards,
padmini.
