Error opening postgres database

[cag8f]

Hi all.  I'm having problems opening a postgres database.  My code:

Local $oConn = ObjCreate("ADODB.Connection")
Local $strConn = "DSN=PostgreSQL;DATABASE=<database name>;SERVER=localhost;Port=5432;Uid=<database username>;Pwd=<database password>"
$oConn.Open($strConn)

My error (at line 3):

D:\test.au3 (5) : ==> The requested action with this object has failed.:
$oConn.Open($strConn)
$oConn.Open($strConn)^ ERROR

Any ideas why this is failing?  

 

Some details that may be pertinent:

 

--system is running Windows 7 32 bit

--postgresql (version 8.3) is installed.  The database exists and is working.

--I can connect to the server and open the database using other third party applications (e.g. PG Admin), so I'm reasonably sure the database name, username, and password are correct.

--I have installed the latest postgresql ODBC driver.  I have also added that DSN to my Control Panel-->Administrative Tools-->Data Sources (ODBC) list.

 

Thanks.
