Re: loosing messages leakes my app...

different approach, still running wired:

the following functions shall apply a hook (and - as far a s i can
debug it, already does it one single time, as expected and
correct... ;-)

===================================================================

//-----------------------------------------------------------------------------
// static handle to last hook
HHOOK& CQControl::_NextHook() {
    static HHOOK hhook = 0;
    return hhook;
}

//-----------------------------------------------------------------------------
// hook into windows to ALWAYS catch Q-Posts ;-/
bool CQControl::_InitHook() {
    if (_NextHook() != 0)
        return true;
    _NextHook() = SetWindowsHookEx(WH_GETMESSAGE, _CtrlHook, (HINSTANCE)
NULL,
        AfxGetThread()->m_nThreadID);
    return (_NextHook() != 0);
}

===================================================================

this is the hook itself:

===================================================================

LRESULT CALLBACK CQControl::_CtrlHook(int code, WPARAM wParam, LPARAM
lParam) {
    switch (code) {
    case HC_ACTION:
        {
            PMSG pMsg = (PMSG) lParam;
            if (pMsg->message != WM_QWCOMMAND)
                break;
            if (pMsg->lParam == 0)
                break;
            SQMsgBlock* pMB = reinterpret_cast<SQMsgBlock*>(pMsg->lParam);
            if (pMB->pControl == NULL)
                break;
            pMB->pControl->_GUIReceived(pMB);
            pMB->pControl->_GUIPostDelete(pMB);
            pMsg->lParam = 0;
            pMsg->message = WM_NULL;
        }

    default:
        break;
    }
    if (code < 0)
        return CallNextHookEx(_NextHook(), code, wParam, lParam);
    return -1;
}

===================================================================

so the pricipial mechanism works: a thread posts a WM_QWCOMMAND-
message and the hook is called. inside, the mesage is processed and
the block deleted. now i want to tell the system to *PLEASE* dont
dispatch it any further: i've tried setting it to WM_NULL, i've tried
returning HC_SKIP, i've tried returning -1,... whatever i do, the
message appears agin in the hook, now pointer to - of course - already
deleted memory... wtf? why does it come again? how do i get rid of it?

TIA, .rhavin;)
