For message pump code for COM STA, my question is, we just need to
copy and past the following code to STA owner thread, no need to
implement any functions to handle msg (e.g. hidden window message
handler)?

Yes, this is sufficient.

If all the message pump code are common, why not COM automatically
generates the code for all STA?

Because you may need a more elaborate message pump. Often, you run your
application's UI on the same thread you are doing COM work on (e.g. you
are hosting an ActiveX control in your window). Depending on your UI
needs, you may want to use APIs like TranslateMessage or
IsDialogMessage.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
