Not sure what version of access you're using or how you are calling the connection..ADO, DAO, .NET
I don't hard code connection strings anymore, but I did when I first started. Nowadays I call a registry function to put the drivers on a specific pc into a listbox and have a setup module which then builds the connection string on the fly from the select listbox value. The below sample may not work, I haven't tested it, but the basic elements are there to help you start thinking about how it does work. The DRIVER= element of the connection must have the name of the driver installed on your pc. Usually they can be found under the ODBC administrator tool, found in Control Panel, Administrative Tools, ODBC Data Source Administrator. If you're creating a DSN-LESS connection, then click the Drivers tab and scroll to the Postgresql drivers The DRIVER= element must exactly match the name of the driver in the [Drivers] tab under the ODBC administrator tool. In the code example below, the driver name on my pc is PostgreSQL ANSI The other elements are well documented Server= (an ip address or hostname of the database server you are connecting to) Port= (Can generally be left at 5432...the postgresql default port) Database= (is the case sensitive name of the postgresql database you are connecting) UID= (postgresql user name to make the connection under) PWD= (the password the connecting user) If you are still having problems, there is the pg_hba.conf file which may block access. You can read about that here. https://www.postgresql.org/docs/9.1/static/auth-pg-hba-conf.html try creating a simple form, add a button, and have the button click event call the below function AFTER you have modified the elements to suit your database name, server etc hopefully some of this info will help make sense Function pg_db_open() as boolean Dim conNew As New ADODB.Connection Dim cs as string cs = "DRIVER=PostgreSQL ANSI; Server=your-server-ip; Port=5432; Database=your-database-name; UID=username; PWD=password" On Error GoTo conError conNew.ConnectionString = cs conNew.Open Set conNew = Nothing pg_db_open = True Exit Function conError: Set conNew = Nothing pg_db_open = False End Function On Fri, 2018-06-01 at 14:27 +0200, Arnaud L. wrote: > Le 01-06-18 à 14:21, Łukasz Jarych a écrit : > > ODBC;DSN=PostgreSQL35W;DATABASE=AccessTest;SERVER=localhost;PORT=5432;*CA=d;A7=100;B0=255;B1=8190;BI=0;C2=;CX=1c305008b;A1=7.4* > > > > When i was searching code for this in internet i found only: > > DRIVER={PostgreSQL > > Unicode(x64)};DATABASE=AccessTest;SERVER=localhost;PORT=5432;UID=postgres;PWD=1234;" > > > > but this is not working, why?
