How to use existing session using COMAPI in C#

By | July 29, 2019

In this blog, we are going to define the use of an existing Sage 300 ERP session with COMAPI in C# .Net. We have already seen about “Create New Session using COMAPI 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. This will be using an existing License and not consume an additional LanPak Users License per session. We will be looking into the steps for using it with C# .Net Code.

New Stuff:  How to use existing session using Advantage API in C#

Step 1:

Include the Sage 300 COMAPI and Session Manager in the project.

Step 2:

Once the COMAPI is included, declare the variable for SingonID and Session. Create the object of Session Manager.

AccpacSession _accpacSession;

int lSignonID = 0;

AccpacSessionManager.AccpacSessionMgr accpacSessionMgr = new AccpacSessionManager.AccpacSessionMgr();

Step 3:

Pass the Sage 300 information and use the existing session to connect to Sage 300 ERP.

accpacSessionMgr.AppID = “AS”;

accpacSessionMgr.ProgramName = “AS3001”;

accpacSessionMgr.ServerName = “”;

accpacSessionMgr.AppVersion = “65”;

accpacSessionMgr.CreateSession(“”, ref lSignonID, out _accpacSession); The application has now connected to existing session of Sage 300 ERP and ready to be used for interaction
