CProgressDlg dlg;
CString tempS;
CBitmap hBitmap;
dlg.Create(IDD_STATUS, NULL);
////////////////////////////////////////////////////
CRect rect;
dlg.GetClientRect(rect);
CAnimateCtrl m_AnimateCtrl;
m_AnimateCtrl.Create(WS_CHILD |WS_VISIBLE,rect,(CWnd*)dlg.FromHandle(dlg.GetSafeHwnd()),0);
m_AnimateCtrl.Open(IDR_AVI_SYNC);
m_AnimateCtrl.Play(0,-1,1);
////////////////////////////////////////////////////////////
dlg.m_Status = "ready...";
dlg.UpdateData(FALSE);
