Hi

I have a VB6 system that interacts with a SQL Server database and GET's
records with the following code

If I_Syscont.State = adStateOpen Then
        I_Syscont.Close
    End If
    szSQL = "select * from syscont"
    szSQL = Trim(szSQL) & " where recno = 1"  'section = '" & DB_wssasfSection & "'"
    If DB_LockMode = 1 Then
        I_Syscont.Open szSQL, ContractDB, adOpenDynamic, adLockPessimistic
    Else
        I_Syscont.Open szSQL, ContractDB, adOpenDynamic, adLockReadOnly
    End If

    I_Syscont.MoveFirst
    etc]
If DB_Lockmode is = 1 it locks the record LockPessimistic.

This GET routine, after changes to certain fields, is followed by a PUT routine as
follow:

If DB_LockMode = 1 Then
    DB_LockMode = 0
  End If
  I_Syscont("RecNo") = sy.recno
  I_Syscont("CoName") = sy.coname
  I_Syscont("LogSeq") = sy.logseq

  I_Syscont("SysDate") = Date 'Now
  I_Syscont("SysUser") = wsuserid

  I_Syscont("FixedWaterMark01") = sy.FixedWaterMark(1)
  I_Syscont("FixedWaterMark02") = sy.FixedWaterMark(2)
  I_Syscont("FixedWaterMark03") = sy.FixedWaterMark(3)

  I_Syscont("FixedWaterMark08") = sy.FixedWaterMark(8)
  I_Syscont("FixedWaterMark09") = sy.FixedWaterMark(9)
  I_Syscont("FixedWaterMark10") = sy.FixedWaterMark(10)


  I_Syscont.update][/CODE]

I assumed this would PUT the record back and then release the lock. However
the lock is not released and the system hangs for anyone else trying to log on.

Pleeeeeaaaase help. If you have the answer please email me on

Close the rs and if you open the rs as read only your following code would generate an error.

PS. Next time you are not creating a snippet but asking a question...

Good Luck

Thanks vb5prgrmr

I am sorry that I did it in the wrong order but I am new to Daniweb.

As for your response my problem is that I am changing the contect of the row so need the row locked. After doing the update I assumed that this would release the record as it does in MSAccess.

Regards

Mac
