I have a timer which was working proeprly before adding threads, now i have added thread funtion after that timer is not displayed on the dialog window can anyone tell me what is the cause ....

--------------
BOOL CStatusDlg::OnInitDialog()
{
CDialog::OnInitDialog();
HANDLE hr;
hr = CreateThread(NULL,0,(unsigned long (__stdcall *)(void *))WorkerThreadProc,this,0,0);
return TRUE;
}

----------------

UINT WorkerThreadProc(LPVOID Param)
{
CStatusDlg* status = (CStatusDlg *)Param;

time(&lStartTime);
SetTimer(NULL,ELAPSED_TIMER, 1000, NULL);
INDX.startIndex();
return true;
}
----------------

void CStatusDlg::OnTimer(UINT nIDEvent)
{
// TODO: Add your message handler code here and/or call default
if(nIDEvent == ELAPSED_TIMER)
{
time(&lStopTime);
cteElapsedTime = CTimeSpan(lStopTime-lStartTime);
CString csElapsedTime;
csElapsedTime.Format("%02d:%02d:%02d",
cteElapsedTime.GetHours(),
cteElapsedTime.GetMinutes(),
cteElapsedTime.GetSeconds());
if(IsWindowVisible())
{
m_TIME.SetWindowText(csElapsedTime);
}
}
CDialog::OnTimer(nIDEvent);
}
