ADO Connection Help

[Guest]

Hi

I am currently using the following code to transfer data into an access
database from an excel file. I want the bit in CAPITALS to be declared as a
variable so that I can just change the location of the database in the
variable. How would I go about changing this? In each of my macros I do not
transfer data to the same table in Access.

Sub ADOFromExcelToAccess()
' exports data from the active worksheet to a table in an Access database
' this procedure must be edited before use
Dim cn As ADODB.Connection, rs As ADODB.Recordset, r As Long
' connect to the Access database
Set cn = New ADODB.Connection
cn.Open "Provider=Microsoft.Jet.OLEDB.4.0; " & _
"DATA SOURCE=C:\FOLDERNAME\DATABASENAME.MDB;"
' open a recordset
Set rs = New ADODB.Recordset
rs.Open "TableName", cn, adOpenKeyset, adLockOptimistic, adCmdTable
' all records in a table
r = 3 ' the start row in the worksheet
Do While Len(Range("A" & r).Formula) > 0
' repeat until first empty cell in column A
With rs
.AddNew ' create a new record
' add values to each field in the record
.Fields("FieldName1") = Range("A" & r).Value
.Fields("FieldName2") = Range("B" & r).Value
.Fields("FieldNameN") = Range("C" & r).Value
' add more fields if necessary...
.Update ' stores the new record
End With
r = r + 1 ' next row
Loop
rs.Close
Set rs = Nothing
cn.Close
Set cn = Nothing
End Sub

I have put the following line in 'ThisWorkbook'

Const kDB As String = _
"DATA SOURCE=C:\FOLDERNAME\DATABASENAME.MDB;"

and also amended the code in each of the macros that need to connect to the
database however, I get an error stating 'Authentication Error'.

Any ideas?

If using in many macros make it global

Public Const kDB As String = _

Sub ADOFromExcelToAccess()> "DATA SOURCE=C:\FOLDERNAME\DATABASENAME.MDB;"
etc.
