vba - Opening a table from another mdb file with ADO in MSAccess -


i'm trying access table mdb file. isn't linked table can fix, please don't suggest it.

edit: part of archive tool creates backup file of backend of database date range, , deletes data. before delete data, suggested check , make sure data copied on created backup. (ie, if worst case scenario happened , share folder lost connection or something, , not data copied over, access database deleted data anyway)

if there's way create linked table in access , delete link in end vba, not manually, maybe work(?) hoping way wouldn't cause database bloat as has been in past.

i'm trying check if data copied on backup file before delete ones in current database.

dim rs adodb.recordset rs.connectionstring = "driver={microsoft access driver (*.mdb)};" & _                  "dbq=backup.mdb;defaultdir=c:\fish;"

i'm having trouble here syntax. know works currentdb, if table in different mdb file? tried defaultdir=c:\fish , defaultdir=c:\fish\ there i'm missing or lot more complicated should attempt?

the rest of think understand how fieldvalues compare, trying connect table in different mdb file giving me trouble.

first of all: gord said in comment, can't see reason against using linked table either.

but in end doesn't matter if create linked table , open local recordset on it, or if open recordset directly on table in other access database.

so i'll show solutions both ways:

1. approach question

your connection string works me, there mistakes in rest of code:

  • an adodb.recordset doesn't have property connectionstring...it's called activeconnection instead.
  • you need create new adodb.recordset before try set connection string or open recordset

the following code works me:

dim rs adodb.recordset set rs = new adodb.recordset  rs.activeconnection = "driver={microsoft access driver (*.mdb)};" & _                  "dbq=backup.mdb;defaultdir=c:\fish;"  rs.open "select * foo"

2. using linked table

create it:

docmd.transferdatabase aclink, "odbc", ";database=c:\fish\backup.mdb", actable, "tablename", "tablenamelocal", false

note: tablename original name of source table, , tablenamelocal name linked table have in local database. (you can use same names if want, of course)

delete it: 

docmd.deleteobject actable, "tablenamelocal"

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
