Mastering PowerBuilder

Connecting to Jaguar CTS from PowerBuilder Application

Okay, we have done all the homework and we are ready to write the code and make use of those objects. First we need to declare a global variable of n_jag_connection, since we need that object throughout the application.

n_jag_connection g_JaguarConnection

Write the following code to connect to the Jaguar server. First, we are creating an instance of the connection object. That will automatically takes care of populating the connection information. Next, we are connecting to Jaguar server by calling ConnectToServer() function.

Object: Application Event: Open IF not IsValid( g_JaguarConnection ) THEN g_JaguarConnection = CREATE n_jag_connection End IF IF g_JaguarConnection.ConnectToServer() <> 0 THEN MessageBox("Jaguar", "Cannot connect to server") HALT CLOSE Else w_mdi_frame.SetMicroHelp( "Connected to Jaguar Server " ) END IF

The following code in the Application Close event disconnects from Jaguar and destroys the instance.

Object: Application Event: Close IF IsValid( g_JaguarConnection ) THEN g_JaguarConnection.DisconnectServer() End IF DESTROY g_JaguarConnection
