I've just started working with PostgresSQL. Currently, we are using version 8.2 on a Windows XP platform for both the
PostgresDB and all other application files.
I am trying to estabish a connection to the database using ODBC (PostgreSQL Unicode driver 8.02.02.00) within a VB.Net
application.When I make the connection as a desktop application, I am able to successfully access the database.
However,when I attempt to make the connection through a VB.Net web application, I am getting the following error:
ERROR [28000] Communication error during authentication; Error while reading from the socket.
I've tried using both direct ODBC functions and ADO objects, with similar problems (i.e. it functions in a desktop
environment,but not through a web environment). An example of my code to access the database is as follows:
Dim szConnect As String = "DSN=mydsnname;UID=myuid;PWD=******"
Dim cnDB As New Odbc.OdbcConnection(szConnect)
cnDB.Open() ' <--- this is where the code fails
Dim dsDB As New DataSet
Dim adDB As New Odbc.OdbcDataAdapter
Dim cbDB As New Odbc.OdbcCommandBuilder(adDB)
adDB.SelectCommand = New Odbc.OdbcCommand("Select * from mytable", cnDB)
adDB.Fill(dsDB)
Any idea why the failure occurs when doing web applications? Is there some set of permissions I have to give to the web
serverprocess or some other code in order to give it permission to run ODBC applications?
