Summary

There are many more things I would like to be able to tell you about automation servers and many more examples I would like to give you, but unfortunately, there is a limit to the size this chapter can be. Therefore, let's quickly recap what you've learned in this chapter and move on.

Active servers come in three flavors:

• A full server is an EXE that can run as both an application and an embedded server. (Optional support can be added for both automation and ActiveX controls.)
• The miniserver is an EXE that can be run in embedded mode only. (Optional support can be added for both automation and ActiveX controls.)
• The automation server (EXE or DLL) exposes classes with methods and properties to allow an external application to control it.

The embedded server can be activated in-place or out-of-place, depending on its implementation and eventual use. It can support persistent storage by serializing data to either the container's storage or a separate file. The server provides a mechanism to display its data on activation (by directly painting the server's view) and while inactive by providing the container with a metafile representation of its data.

The automation server can run in-process (meaning that it runs in the same process space as the application that created it) or out-of-process (meaning that it runs in its own process space).
