Preserving linked tables for Access DBs in same folder when the folder changes

Question

I\'ve got two Access databases that share linked tables. They are deployed together in a directory and accessed via code in a Word form.

How can I make sure that the

Answer 1

Renaud's answer no longer works in Access 2010 with Excel or CSV files.

I have made a few modifications:

• Adapted to the current pattern for the connection string
• Handled the database path differently for Excel files (includes filename) and CSV files (does not include filename)

Here is the code:

Public Function RefreshLinksToPath(strNewPath As String, _
Optional OnlyForTablesMatching As String = "*") As Boolean

Dim collTbls As New Collection
Dim i As Integer
Dim strDBPath As String
Dim strTbl As String
Dim strMsg As String
Dim strDBName As String
Dim strcon As String
Dim dbCurr As DAO.Database
Dim dbLink As DAO.Database
Dim tdf As TableDef

Set dbCurr = CurrentDb

On Local Error GoTo fRefreshLinks_Err

'First get all linked tables in a collection'
dbCurr.TableDefs.Refresh
For Each tdf In dbCurr.TableDefs
    With tdf
        If ((.Attributes And TableDefAttributeEnum.dbAttachedTable) = _
           TableDefAttributeEnum.dbAttachedTable) _
           And (.Name Like OnlyForTablesMatching) Then
            Debug.Print "Name: " & .Name
            Debug.Print "Connect: " & .Connect
            collTbls.Add Item:=.Name & ";" & .Connect, Key:=.Name
        End If
    End With
Next
Set tdf = Nothing

' Now link all of them'
For i = collTbls.Count To 1 Step -1
    strConnRaw = collTbls(i)
    ' Get table name from the full connection string
    strTbl = Left$(strConnRaw, InStr(1, strConnRaw, ";") - 1)
    ' Get original database path
    strDBPath = Right(strConnRaw, Len(strConnRaw) - (InStr(1, strConnRaw, "DATABASE=") + 8))
    ' Get the name of the linked database
    strDBName = Right(strDBPath, Len(strDBPath) - InStrRev(strDBPath, "\"))
    ' Get remainder of connection string
    strConn = Mid(strConnRaw, InStr(1, strConnRaw, ";") + 1, InStr(1, strConnRaw, "DATABASE=") _
                - InStr(1, strConnRaw, ";") - 1)

    ' Reconstruct the full database path with the given path
    ' CSV-Files are not linked with their name!
    If Left(strConn, 4) = "Text" Then
        strDBPath = strNewPath
    Else
        strDBPath = strNewPath & "\" & strDBName
    End If

    ' Reconnect '
    Set tdf = dbCurr.TableDefs(strTbl)
    With tdf
        .Connect = strConn & "Database=" & strDBPath
        .RefreshLink
        collTbls.Remove (.Name)
    End With
Next
RefreshLinksToPath = True

fRefreshLinks_End:
    Set collTbls = Nothing
    Set tdf = Nothing
    Set dbLink = Nothing
    Set dbCurr = Nothing
    Exit Function

fRefreshLinks_Err:
    RefreshLinksToPath = False
    Select Case Err
        Case 3059:

        Case Else:
            strMsg = "Error Information..." & vbCrLf & vbCrLf
            strMsg = strMsg & "Function: fRefreshLinks" & vbCrLf
            strMsg = strMsg & "Description: " & Err.Description & vbCrLf
            strMsg = strMsg & "Error #: " & Format$(Err.Number) & vbCrLf

            Resume fRefreshLinks_End
