Dear Experts,
I am trying to find a vba code in access which on prompt refresh and relinks the SQLite tables, having both front-end and back-end databases on same machine, the following code from Dev Ashish (Access mvp)works fine for Access-Access links, but I cannot configure it to work for Access-SQLite table links,I am a basic user and need help to work it out. thanks
Code from Dev Ashish:
Function fRefreshLinks() As Boolean
Dim strMsg As String, collTbls As Collection
Dim i As Integer, strDBPath As String, strTbl As String
Dim dbCurr As DATABASE, dbLink As DATABASE
Dim tdfLocal As TableDef
Dim varRet As Variant
Dim strNewPath As String
Const cERR_USERCANCEL = vbObjectError + 1000
Const cERR_NO
On Local Error GoTo fRefreshLinks_Err
If MsgBox("Are you sure you want to reconnect all Access tables?", _
vbQuestion + vbYesNo, "Please confirm...") = vbNo Then Err.Raise cERR_USERCANCEL
Set collTbls = fGetLinkedTables
Set dbCurr = CurrentDb
strMsg = "Do you wish to specify a different path for the Access Tables?"
If MsgBox(strMsg, vbQuestion + vbYesNo, "Alternate data source...") = vbYes Then
strNewPath = fGetMDBName("Please select a new datasource")
Else
strNewPath = vbNullString
End If
For i = collTbls.Count To 1 Step -1
strDBPath = fParsePath(collTbls(i))
strTbl = fParseTable(collTbls(i))
varRet = SysCmd(acSysCmdSetStatus, "Now linking '" & strTbl & "'....")
If Left$(strDBPath, 4) = "ODBC" Then
Else
If strNewPath <> vbNullString Then
strDBPath = strNewPath
Else
If Len(Dir(strDBPath)) = 0 Then
strDBPath = fGetMDBName("'" & strDBPath & "' not found.")
If strDBPath = vbNullString Then
Err.Raise cERR_USERCANCEL
End If
End If
End If

strTbl = fParseTable(collTbls(i))
