Re: Connecting to Postgres using Windows 7

----- Original Message ----- From: Geoffrey Becker

I'm relatively new to postgres.  I've got a Visual Basic (VB)
application that i would like to connect to a Postgres database using
ODBC .  Both the VB application and postgres are on my laptop and both
work beautifully independent of each other.  Trouble is, I have a
windows 7 64bit OS and therefore I have been unable to get VB to connect
to the database.  My code is as follows:

    Public Class Form1

        Dim cCon As ADODB.Connection

        Private Sub Button1_Click(ByVal sender As System.Object, ByVal
e As System.EventArgs) Handles Button1.Click

            On Error GoTo EH

            cCon.ConnectionString =
"DSN=MyDatabase;uid=MyUserID;pwd=MyPassword"

Is this your actual connection string?  If your using a DSN does it
specify the Server Name and Port where PostgreSQL is listening?

See: http://www.connectionstrings.com/postgre-sql

            cCon.Open()
            MsgBox("O.K.", vbInformation, "Connection Message")
            Exit Sub
    EH:
            MsgBox(Err.Description, vbCritical, "Error Message")
        End Sub

        Private Sub Form1_Load(ByVal sender As System.Object, ByVal e
As System.EventArgs) Handles MyBase.Load
            cCon = New ADODB.Connection
        End Sub
    End Class

When I try to connect, all I get is a "Server does not exist or access
is denied" error.  I've tried configuring ODBC using odbcad32.exe as it
seems that is necessary on a 64 bit OS, but I'm not sure if that even
the right way to go.

You may need to install the psqlODBC 64 bit driver if you trying to connect from a 64 bit machine.

Any help i could get would be much appreciated.

Thanks,

Geoff
