ISystemDebugEventInstall Example (Visual J++)

   

The following code shows the use of all methods in ISystemDebugEventInstall. In order to modify this code for your own use, you need to add error handling. Each method can raise errors, which you should make sure to trap. You can use the Windows® application Guidgen.exe to generate globally unique IDs (GUIDs) where required.

Use ISystemDebugEventInstall to register the component that will generate events and the events that component will generate. After you finish the registration process, you can generate events. ISystemDebugEventFire provides methods for generating events.

// Import required class libraries.
import vaesa.*;

// Declare an event installer object.
static ISystemDebugEventInstallAuto m_ESA = null;

// Now generate GUIDs for the component that will generate VSA events, as
// well as a custom event category, a user-defined event, a dynamic
// component, and the CLSID of a COM component that implements the
// dynamic event interface. The CLSID is used when you want Visual Studio
// Analyzer to start the dynamic component automatically.
