Accessing a Service from Visual Basic

This guide is your reference for developing COM applications that use TIBCO GridServer® installations. It is divided into several sections covering the fundamentals of how to use the GridServer COM API.

In this section, we demonstrate how to access a Service from a client application written in Visual Basic, using COMDriver. The example shows how a Visual Basic client can call COMDriver APIs to create and destroy a Service instance, execute the Service synchronously or asynchronously, and update the state of the Service. Although the Service in this example is a Java Service, client applications using COMDriver can access Services written in any server-side compatible language, provided that Service methods use strings for arguments and return values.
