Help comparing strings

P: n/a
I am trying to use the following code to reset a custom counter:
(I forgot where I got the code but it's not my own and I did not remove
and credits, this is how it came)

Function Next_Custom_Counter()
'''''''''''''''''''''''''''''''''''''''''''''''''' ''''''''''''
'For this code to work, it is required that you reference the:
' Microsoft ActiveX Data Objects 2.x Library
'To reference this library, go to the Tools menu, click
'References, and select the library from the list of available
'references (version 2.1 or higher).
'''''''''''''''''''''''''''''''''''''''''''''''''' ''''''''''''
On Error GoTo Next_Custom_Counter_Err

Dim rs As ADODB.Recordset
Dim NextCounter As Long
Dim PrefixA As String
Dim PrefixB As String
Set rs = New ADODB.Recordset

'Open the ADO recordset.
rs.Open "CounterTable", CurrentProject.Connection, adOpenKeyset,
adLockOptimistic

'Get the next counter.
NextCounter = rs!nextavailablecounter
PrefixA = rs!CurrentPrefix 'stored in table as format(Date,"yymmm")
PrefixB = Format(Date, "yymmm")

'''''''''''''''''''''''''''''''''''''''''''''''''' ''''''''''''''''
'Open table and get the current value of NextAvailableNumber,
'increment the value by 10, and save the value back into the table
'
'The next line can be changed to conform to your custom counter
'preferences. This example increments the value by 10 each time.
'''''''''''''''''''''''''''''''''''''''''''''''''' ''''''''''''''''

If StrComp(PrefixA, PrefixB, vbTextCompare) = 0 Then
MsgBox ("same")
GoTo Increase
Else
GoTo Reset
MsgBox ("different")
End If
Increase:

rs!nextavailablecounter = NextCounter + 1
NextCounter = rs!nextavailablecounter
rs.Update

rs.Close

Set rs = Nothing

Next_Custom_Counter = NextCounter

Exit Function
Reset:
rs!nextavailablecounter = "0000"
rs.Update
rs.Close

Set rs = Nothing
Exit Function

[/code]

Nothing happens during the if statement. It will not even pass along
the custom counter to the call from the form. What I understood from
the A2K helpfile is that if the strings were equal it would return a 0.
What I want it to do is if the prefixb (IE: 05APR) is the same as the
current prefix (IE:05APR) then nothing happens and the counter
continues on. If there is a difference (IE: different year or month)
the counter is reset to 0.

Any help would be greatly apprecetaed as midnight trips to work to
reset the number manualy is getting old.

Next_Custom_Counter_Err:

If Err <> 0 Then Resume
End
End Function

Surely something is happening in the If statement, if in fact code
execution makes it that far since the If...part handles one condition
and the Else handles any other possible condition!

Try setting a breakpoint on the 'If StrComp...' line and run the code.
Examine the contents of PrefixA and PrefixB to see if they're really
what you think they should be. Then step through a line at a time and
see what's going on.
