Hello,

I use LLBLGen Pro 2.6 final. I got the software installed on my machine as well as the project I started to work on. So I try to refresh the catalog.

I get stuck on "retrieving schema 'db_accessAdmin'" till I get the error [DBNETLIB][ConnectionOpen (Invalid Instance()).]Invalid connection.

I use Microsoft SQL Server 2008 R2 and connect with DB credentials

Here is what I did so far according to previous posts: - opened ports 1433 1434 and other ports needed according to http://blogs.msdn.com/b/jorgepc/archive/2009/08/25/open-firewall-ports-for-sql-server-the-easy-way.aspx - the UAC is at its lowest level - re installed LLBL Gen - ran LLBL Gen as an admin

So I am running out of ideas.

Can anyone help me please? Thank you

Did you add the port number to the connection string?

Could you explain this step a little bit more?

Where do I add the port to SQL Express?

Thank you

In LLBLGen Pro Designer, when you connect to the database, you write the server name (SQLExpress was just an example), all you need to do is to add the port.

In the following format SERVER_NAME, port_no.

example: SQLServer, 1434

I got it, I was trying port 1234...

It worked with 1433.

Now I would like to know is it specific to SQL Express? Another developer gave me the procedure to follow and he only specifies the server IP address without any port.

Thank you anyways

If you are running more than one instance on your server, this might be the cause.
