How to manage user messege sent by PostThreadMessage

[aragornx]

Hi - I have problem with receiving a message sent by PostThreadMessage. I'm posting message from main application class (CWinApp). I'm posting it to my class derived from CWinThread. Part of my thread class code:
CReaderThread.h

CReaderThread : public CWinThread {
[...]
afx_msg void OnMessageTest( WPARAM, LPARAM );
protected:
	DECLARE_MESSAGE_MAP()
[...]
}

in CReaderThread.cpp

BEGIN_MESSAGE_MAP(CReaderThread, CWinThread)
	ON_THREAD_MESSAGE( WM_MESSAGE_TEST, OnMessageTest )
END_MESSAGE_MAP()

BOOL CReaderThread::InitInstance() {
	TRACE( _T("CReaderThread::InitInstance() START\r\n") );
	if ( reader != NULL ) {
		if ( start() == true ) {
			mainLoop();
		}
	}
	stop();
	TRACE( _T("CReaderThread::InitInstance() STOP\r\n") );
	AfxEndThread(0);
	return TRUE;
}

void CReaderThread::mainLoop() {
	long startTime = 0x00;
	long endTime = 0x00;
	long time2wait = 0x00;
	MSG msg;
	while ( CRealtime::getInstance()->isWorking() ) {
		startTime = GetTickCount();
		if ( PeekMessage(&msg, NULL, WM_USER, WM_USER, PM_NOREMOVE) ) {
			TRACE( _T("RECEIVED message : %i\r\n"), msg.message);
		}
                [...]
                ::WaitForSingleObject( stopEvent->m_hObject, time2wait );
        }
}
void CReaderThread::OnMessageTest( WPARAM wP, LPARAM lP ) {
	TRACE( _T("Get Message wP=%i, lP=%i\r\n"), wP, lP );
	return;
}
BOOL CReaderThread::PreTranslateMessage(MSG* pMsg) {
	if ( pMsg->message == WM_MESSAGE_TEST ) {
		OnMessageTest( pMsg->wParam, pMsg->lParam );
	}
	return CWinThread::PreTranslateMessage(pMsg);
}

I set breakpoints after PeekMessage(), in OnMessageTest() and in PreTranslateMessage() - nothing. Messages are lost. How to make my thread to receive sended messages?
Greetings.
