Although you must use a component wrapper for hosting an ActiveX control, you can write an Automation controller using only the definitions from the type library that appear in the TypeLibName_TLB unit. This process is a bit more involved that letting a component do the work, especially if you need to respond to events. 

The following topics describe how to implement the various actions your Automation controller needs to perform:

• Connect to the server.
• Control the Automation server using a dual interface.
• Control the Automation server using a dispinterface.
• Respond to events generated by the Automation server.
