Custom messages start from WM_APP, so you can do this

#define WM_MYMESSAGE1 (WM_APP+1)
#define WM_MYMESSAGE2 (WM_APP+2)

Remember that these message are valid only in your application.
See here (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/windowing/messagesandmessagequeues/messagesandmessagequeuesreference/messagesandmessagequeuesmessages/wm_app.asp) also.

If you want a system wide message look at RegisterWindowMessage (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/windowing/messagesandmessagequeues/messagesandmessagequeuesreference/messagesandmessagequeuesfunctions/registerwindowmessage.asp).
