Messages window procedure

Everything in Windows is communicating through these messages.

See http://msdn.microsoft.com/en-us/library/ms644950(v=vs.85).aspx[^], http://msdn.microsoft.com/en-us/library/ms644944(v=vs.85).aspx[^].

You won't be able to work with them without understanding of basic Windows architecture. Find any book on raw Windows programming.
For a basic idea of messages, see:
http://msdn.microsoft.com/en-us/library/ms632590(v=vs.85).aspx[^],
http://msdn.microsoft.com/en-us/library/ms644927(v=vs.85).aspx[^].

You will be able to find the list of messages in the source code of Windows API in any language.
You can also find it here:
http://www.autohotkey.com/docs/misc/SendMessageList.htm[^].

When you know a named for a message (this is a second parameter in SendMessage or PostMessage), you can get help on every particular message ID which will show you the meaning and set of other parameters of the message.

You might like to take help from someone who knows some English.
Even after translation, it is not making much sense.

Try reposting with guidance and I'm sure someone will help you out here.

Меня тоже заинтересовало оконное сообщение 0xc0b4, впервые увидел его под семеркой.
Вот это "0xc0b4, L"Registred:TaskBarButtonCreated"" - я выдрал с помощью Spy++.

Я думаю, тобой обозначено семейство регистрируемых сообщений. То, что 0xc0b4 регистрируется (RegisterWindowMessage) самой системой - у меня не вызывает сомнений, кому принадлежат остальные - не смотрел. Удачи, земляк =)
