Using the ServiceProcessInstaller Class in VB.net

By: Steven Holzner

ServiceProcessInstaller objects install the specific processes in a Windows service. Here is the inheritance hierarchy of this class:

Object
   MarshalByRefObject
      Component
         Installer
            ComponentInstaller
               ServiceProcessInstaller

You can find the more notable public properties of objects of the ServiceProcessInstaller class in Table 7, their more notable methods in Table 8, and their more notable events in Table 9. Note that I'm including the properties, methods, and events inherited from the Installer and ComponentInstaller classes in these tables.
