Hi Dawn,
Please see result of sp_helpsort below and advise where should we look for the default charset.
Also, below is the connection string we issued in Visual Basic, which is not working as well. Please check this too.
tConnectString$="Driver=Adaptive Server Enterprise;NA=XXXXX,5006;Uid=XXXXX;Pwd=XXXXX;Database=XXXXX;charset=cp850;"
