How do I find my Connection String required to automate SAP GUI through a C# application?
automation, c#, connection-string, sap-gui
Solution
Use this line of code: Connection = Application.OpenConnectionByConnectionString("/H/IP Address/S/3200", false, true);
H: Host IP Address S: Host Port Number. Default is 3200. Check yours.
Problem
I am trying to make a connection to SAP GUI through C#. For reference, I am using code found here: How do I automate SAP GUI with c# I have added a reference to sapfewse.ocx and the corresponding using statement. Here is my code: ``` using SAPFEWSELib; private void OpenSAP() { GuiApplication Application; GuiConnection Connection; GuiSession Session; Application = (GuiApplication)System.Activator.CreateInstance(Type.GetTypeFromProgID("SapGui.ScriptingCtrl.1")); // How do I find the connection string that I use to connect to SAP? Connection = Application.OpenConnectionByConnectionString("XXXXXXXXX", false, true); Session = (GuiSession)Connection.Sessions.Item(0); Session.TestToolMode = 1; ((GuiTextField)Session.ActiveWindow.FindByName("RSYST-MANDT", "GuiTextField")).Text = "XXX"; ((GuiTextField)Session.ActiveWindow.FindByName("RSYST-BNAME", "GuiTextField")).Text = "XXXXXXXX"; ((GuiTextField)Session.ActiveWindow.FindByName("RSYST-BCODE", "GuiPasswordField")).Text = "XXXXXXXX"; ((GuiTextField)Session.ActiveWindow.FindByName("RSYST-LANGU", "GuiTextField")).Text = "XX"; } ``` I am getting an error when I run this code saying ...connection broken How can I be sure of the correct connection string to use? Where can I find the connection string that I use to connect to SAP? Or is there a better way than using the `OpenConnectionByConnectionString()` method?
