Access 2003 - Opening a database from a module used in Access 97

I have a function which is used for updating a field in a table.
The database has been converted from 97 to 2003.
The DAO 3.6 Library is ticked under References.
But despite trying to follow other examples I keep getting runtime errors.

I'm sure this is as simple as it gets but it's defeated me as a non-programmer!

Public Function UMailsortExistingCodes()

ENDFILE = "NO"
Dim MYDB As Database
Dim ALPHA As Recordset
Set MYDB = DBEngine.Workspaces(0).Databases(0)
Set ALPHA = MYDB.OpenRecordset("ALPHA", DB_OPEN_TABLE)

ALPHA.Index = "SORT"

ALPHA.MoveFirst

Do Until ALPHA.EOF
    
    With ALPHA
        .Edit
        
        If Not IsNull(ALPHA![CODE]) Then
    
    If Left(ALPHA![POSTCODE], 4) = "MK1 " Then [ALPHA]![CODE] = "14735"
    If Left(ALPHA![POSTCODE], 4) = "MK2 " Then [ALPHA]![CODE] = "14735"
    If Left(ALPHA![POSTCODE], 4) = "MK3 " Then [ALPHA]![CODE] = "14735"
    
        .Update
        
    End If
    
        ALPHA.MoveNext
    End With

Loop

ALPHA.Close

End Function

You will have to post details of the error/s you are getting.
There is nothing basically wrong with the code you posted.

You can change a couple of lines as below to get them up-to-date..

Dim ALPHA As DAO.Recordset
Set MYDB = DBEngine.Workspaces(0).Databases(0)
Set ALPHA = MYDB.OpenRecordset("ALPHA", dbOpenTable)

but these should not really affect the success of your application.

Open any module and try Debug>Compile and see if you have any errors reported.

If I try Debug>Compile I get errors from some message statements in the forms section!

I've changed the lines as you suggested.

When I try to run the function it falls over on line 7:
Set ALPHA = MYDB.OpenRecordset("ALPHA", dbOpenTable)

Runtime error 3219
Invalid operation

how about doing this

dim rsAlpha as dao.recordset, mydb as dao.database
set mydb=DBEngine.Workspaces(0).Databases(0)
set rsAlpha=mydb.openrecordset("Alpha")

Have you also split your database into frontend and backend as well as converting it?
That would be an explanation for that  error message.

I don't like the code in that the name Alpha is used for two different objects; but I don't see that actually causing a problem except in trying to read the code.

Is the table spelled correctly (hasn't been changed) and is linked or exists in the database that's trying to run the code.?

Also, I haven't use workspaces in a long time...

Dim MYDB AS DAO.DATABASE
Dim ALPHA As DAO.Recordset
Set MYDB = CODEDB  '---- like saying "me.mydatabase".
Set ALPHA = MYDB.OpenRecordset("ALPHA", dbOpenTable)

Thanks everyone for the response.
Yes the database is split - however, I'm running this from the 'main' copy which contains all the tables.
I'll try some of the other suggestions and get back to you.
However, I'm now at home and not due in the office until Monday so I'll need to use RWW before then to access the server.

You can't use this code on a split database.  It only works for tables that are physically in the same file as the code.

So you need to change these two lines..

Set ALPHA = MYDB.OpenRecordset("ALPHA", DBOPENTABLE)
ALPHA.Index = "SORT"

to...
Set ALPHA = MYDB.OpenRecordset("Select * from ALPHA order by [Sort]", dbopendynaset)

(Delete ALPHA.Index = "SORT")

Excellent - that did the trick!
Many thanks everyone.
I've assigned the full amount of points to peter57r because he not only provided the solution but also asked whether the database was split!

Is there a website/ resource out there that highlights some of the more common pitfalls when converting from 97 to 2003? I have to say there have been no real problems in the last 4 months since it was converted but I suspect something else is probably waiting to bite.
