Maybe a stupid question ??
Fra : Dag Eriksen


Dato : 16-01-03 13:43

This might be very simple, but it is a large problem for me :

I have 2 Access MDB files on a Web server (using Frontpage 2002) in a folder
called /fpdb.
I am trying to create a query in one of the MDB's using data from the other
MDB,
but I can't make this work. I think I have tried almost everything.

I can be solved by only using one MDB file, but this is not a good solution
to me.

If anyone knows the answer to this, I will be most greatful.

Dag Eriksen

It hard to figure otu what your problem is but basically you need to
make a connectionobject to each database.

it should also be possible to make a connection from one Access-
database to the other. The access to the other resources in the
other database would be transparent and work as if accessing a
table or query directly.

I am not sure, though, if this requires physical access to the
server in question.

Why not just open one DB in Access? Make a link to the other DB's table and
you're off in ASP...no problems.

Heres what I mean, given 2 Access DB's:

1. Open DB1 in Access.
2. Right-click in the "tables" view.
3. Choose "Link tables" or something like that (not import)
4. Choose DB2 and then the Tabel in question.
5. Specify a table name.

Now you have a table in DB1 that "points" to DB2. The data is still in DB2,
ie, if you change or update the table in DB2 the data is automatically
changes in DB1 and vice versa.

You can adress the table via ASP in DB1 as any other table.

Hope this brings you further,
/TH

the problem wirh this approach - at least it was when I tried it last -
is that Access uses the specific path to the other db instead of just
using a relevant path. This means that there will be no problems when
doing this on the webserver itself. but if it is done locally - and then
the DBs are uploaded to the webserver, the specific path does no longer
validate - and the relations become useless.

Good point...I didnt know that....Hope you are following Dag, because this
is quite important :)

You can however specify another path (relative or absolute) after you have
linked the table. Choose to see system-objects in the "options"->"show"
dialog of Access....

You will then see a couple of system (hidden) tables. In these tables access
saves all specific information about well...everything actually :) Open the
"MSysObjects" table and inthere you will find the path to DB2....change it
to suit your needs on the webserver...

:)

Hello again !
It seems like were getting to the core of the problem.
I can not find "Choose to see system-objects in the "options"->"show"

First of all...Do you have a "options"->"show" dialog?
It should be there...What version of Access are you using?

In the menu "options" you have a sub-menu called "security". There you will
find antoher sub-menu called "user and group permissions" or something like
that. There you can see that "administrator" needs read/write access to the
MSystemObjects-database.

Dag: Make a copy of your Access database before altering this table :)

Even with changing the parameters as you describe, I am not able to change
the data.

Hi,

Well you got me thinking now...
Afaik there are only 2 ways to change this...1) via the Link-manager 2) via
Code.

Ad 1)
the link manager is not installed pr default. Run the Office/Access
installation again and you should be able to installa this.

Ad 2)
1. Make a new module. (eg "module1")
2. Insert the following 2 functions:

Function CheckAttachedTable(strTable As String, strNewPath As String) As
Integer

' Checks the named table and attempts to reattach it if
' it's not attached properly.
'
' In:
' strTable - table to check
' strNewPath - path to connect to if test fails
' Out:
' Return Value - True if successful, False otherwise.

Dim db As Database
Dim rst As Recordset

Set db = DBEngine.Workspaces(0).Databases(0)

On Error Resume Next
Set rst = db.OpenRecordset(strTable, DB_OPEN_DYNASET)

' Check for failure. If the OpenRecordSet failed, then
' attempt to reattach the table.
If Err <> 0 Then
If Not ReAttachTable(strTable, strNewPath) Then
MsgBox "Could not reattach table '" & strTable & "'"
CheckAttachedTable = False
End If
Else
rst.Close
CheckAttachedTable = True
End If
On Error GoTo 0
End Function

Private Function ReAttachTable(strTable As String, strNewPath As String) As
Integer

' Reattaches the named table to the named path
' In:
' strTable - table to reattach
' strNewPath - path to attach to
' Out:
' Return value: True if successful, False otherwise

Dim db As Database
Dim tdf As TableDef

' Assume success.
ReAttachTable = True

Set db = DBEngine.Workspaces(0).Databases(0)
Set tdf = db.TableDefs(strTable)

' If Connect is blank, it's not an attached table
If Len(tdf.Connect) > 0 Then
tdf.Connect = ";DATABASE=" & strNewPath

' The RefreshLink might fail if the new path
' isn't OK. So trap errors inline.
On Error Resume Next
tdf.RefreshLink
ReAttachTable = (Err = 0)
On Error GoTo 0
End If
End Function




3. Call "CheckAttachedTable(strTable As String, strNewPath As String)"
somewhere...eg a new button in a form. something like this:

Dim testInt as Integer
testInt = CheckAttachedTable("linkedname", "c:\blabla\db2.mdb")


Well...If this doesnt help you im kinda lost....
Try searching the web for "access edit msysobjects" or something like
that...there should be lots of routines outthere to deal with this
issue...:)

I have read your original post again, and to be honest....the quick method
is to adress both databases/tables in ASP...I would do it that way....and
just ignore the last 5-6 postings here :)

You know that you use eg: "set conn=....." in ASP right? Then just make a
new connection at the same time to DB2....like this "set conn2=....."

?
