"Linked Table Manager" from within VB.

My application, written in Access 2000, is supposed to have a function for linking to tables in a separate .mdb-file. This file is always the same, but can be placed i diffent locations into different drives. From the Access menu I use "Linked Table Manager". How can I do the same from a runtime application.

Linked tables have a '.Connect' property, which is not an empty string.

Loop through all of the tables in code, (setting a tableDef object), looking for the .Connect property.  When you find one, change it to the proper path, then use the .RefreshLink method of the TableDef object that you have set the .Connect property of.


     Dim t As tableDef
     Dim d as Database
     Set d = CurrentDB

     For each t in d.TableDefs
          If t.Connect <> "" THen
               ....
               ' Set the .Connect here.
               t.RefreshLink
          End If
     Next t
     Set t = Nothing
     Set d = Nothing

i had the same hassle, the code from brianwren is fine i had a slightly different approch as not all my tables were in the other db so mine is probably a little longwinded i also stored the location in a small table in the local database and so had some code to prompt for the location if it changed, just simpel in a msgbox format, but i supposed you could get fancy and use a browse box, here is my code still has my table names and  fields but i'm sure you get it...
the first part gets the location from the table(strLocation) so that is like "c:\data\local\test.mdb" or whatever then just refresh all the links that you need to....

    Dim strLocation As String
    Set db = CurrentDb
    strSQL = "SELECT simpay.Data FROM simpay;"
    Set rst = CurrentDb.OpenRecordset(strSQL)
    strLocation = rst(0)
    Set rst = Nothing
   
    Set tbl = db.TableDefs("tblloans")
    tbl.Connect = ";DATABASE=" & strLocation & ""
    tbl.RefreshLink
    Set tbl = db.TableDefs("tblPayments")
    tbl.Connect = ";DATABASE=" & strLocation & ""
    tbl.RefreshLink
    Set tbl = db.TableDefs("tblSettings")
    tbl.Connect = ";DATABASE=" & strLocation & ""
    tbl.RefreshLink
    Set tbl = db.TableDefs("tblTimesheet")
    tbl.Connect = ";DATABASE=" & strLocation & ""
    tbl.RefreshLink
    Set tbl = db.TableDefs("tblYee")
    tbl.Connect = ";DATABASE=" & strLocation & ""
    tbl.RefreshLink
    Set tbl = db.TableDefs("temp")
    tbl.Connect = ";DATABASE=" & strLocation & ""
    tbl.RefreshLink
Set tbl = Nothing

hope that helps..

When I had this problem, I did this:



    Dim strLoc As String
    Dim d    As Database: Set d = CurrentDb

    strSQL = "SELECT simpay.Data FROM simpay;"
    Set rst = d.OpenRecordset(strSQL)
    strLoc = ";DATABASE=" & rst(0)
    Set rst = Nothing
   
    Redim Ts(6) As String
              Ts(1) =  "tblloans"
              Ts(2) =  "tblPayments"
              Ts(3) =  "tblSettings"
              Ts(4) =  "tblTimesheet"
              Ts(5) =  "tblYee"
              Ts(6) =  "temp"

    For i = 1 To 6
        Set tbl = d.TableDefs(Ts(i))
        tbl.Connect = strLocation
        tbl.RefreshLink
    Next i
    Set tbl = Nothing
