How to use existing session using Advantage API in C#

By | July 29, 2019

In this blog, we are going to see use of an existing Sage 300 ERP session with Advantage API in C# .Net. We have already seen about “Create New Session using Advantage API in C#” in our earlier blog. Since we already know that session is must to interact with Sage 300 and for some developers when they do not have enough knowledge about the Sage 300 API it becomes tedious job to use the same. We will be looking into the steps for using it with C# .Net Code.

Step 1:

Include the Sage 300 Advantage DLL in the project.

Step 2:

Once the Advantage DLL is included, create the object of the Session.

Session _session = new Session ();

Step 3:

Initialize the session object with Sage 300 ERP.

_session.INit(“”, “AS”, “AS3001”, “65”);

Step 4:

Check whether session is already open. Open the session only if currently not available.

if (!_session.IsOpened)

            _session.Open(“ADMIN”,”ADMIN”,”SAMLTD”, DateTime.Today, 0);

The application will not open the new session and use the existing session. If there is no session available only then new session will get open to connect the object of Sage 300 ERP.
