>it gaves me an Invalid Descriptor error..
The error means that you are refering to a file handle or a socket that is invalid ... most common cause would be to try to read a file/socket before opening it or after closing it

Check the line which shows the error to determine if the file or socket handle that you are using is indeed valid

what language? what OS ?

look for the source line which generates the error .... find all descriptors in that line .... trace those descriptors back to find which one of them in invalid

If the error message is "Invalid Descriptor Index", then the problem could relate to MSC CRecordset (ODBC).  You'll need the source code to fix it.
