I'm programming "extensions" to a main application that is made by another corporation in VB. And I made it fine. Works beautiful. The extensions are all DLL. The main server: Microsoft SQL 2000 Server. It's fine. All works fine. Every extension is a DLL. Every DLL has a lot of units. And ONE Data Module -i love this-. But I'm very worried about the following. All DLL's have lot of procedures inside, and sometimes one calls each other. Every procedure create one instance of the Data Module and the DataModule creates a SQL connection. So, every connection consumes one license on the SQL server. My question: I would like to create one DLL for the connection with the server and I want that all my DLLs uses that "dll connector" to work. is this possible? how? If the ADO Connection component is inside this "DLL connector" , How can the-others-DLL access to this ADO Connection?

I do not believe this is accurate. I believe each computer/workstation is considered a client or license. Not each connection. -Steve- Back to top Pablo Romero Guest Posted: Thu Jan 19, 2006 2:46 pm    Post subject: Re: About ADO connections and DLL My friend: are you sure the connection is not a license?

If each AdoConnection was equal to one client license, I think my applications would be crashing all over the place. It would also make development extremely difficult. If you want to ease your mind, just create an application with 20 connections and run it against a 5 or 10 client server. -Steve- "Pablo Romero" <info (AT) pabloromero (DOT) com.ar> wrote Quote: My friend: are you sure the connection is not a license?
