在CMainFrame::OnAppExit()中，调用CFrameWnd::OnClose(),应用程序退不出来？急！！！！！！

[xiaohonghong]

求救：我在CMainFrame::OnAppExit()中，调用CFrameWnd::OnClose(),应用程序退不出来，调用::PostQuitMessage(0)，也不行，在Debug版本下，程序会出错，提示是：arning: calling DestroyWindow in CWnd::~CWnd; OnDestroy or PostNcDestroy in derived class will not be called.
继续运行，在Call Stack中 会出现：_com_ptr_t<_com_IIID<_Connection,&_GUID_00000550_0000_0010_8000_00aa006d2ea4> >::_Release() line 662 + 15 bytes

好象是Ado的_ConnectionPtr没有关闭，而我确实调用了关闭该连接。
我的OnAppExit程序如下：
void CMainFrame::OnAppExit()
{
// TODO: Add your command handler code here

if(g_Started)
{
//AfxMessageBox("请先结束测试，再关闭系统！");
CMsgDlg dlg;
dlg.m_strMsg = "请先结束测试，再关闭系统!";
dlg.DoModal();
return;
}
CMsgDlg dlg;
dlg.m_strMsg = "你真的要退出本系统么？";
dlg.m_bCancelShow = true;

if(dlg.DoModal() == IDCANCEL)
return;

第一个提示
m_pEquipErrListDlg->DestroyWindow();
delete m_pEquipErrListDlg;

第二个错误好像有对象没释放，加这个
g_ConnectPtr->Release();

区定所有对象都释放了在调用::CoUninitialize();

楼上，不行啊，我这样也试过了

[Phourm]

DestroyWindow();

[xqk]

up

[vcmute]

PostMessage(WM_CLOSE);

[godsmile]

SendMessage(WM_CLOSE);

继续运行，还会出现如下错误：

如果相退出应用程序：
this->PostMessage(WM_CLOSE, 0, 0);

CThrRecord是从CWinThread继承来的么，如果是
if(pThrRecord)
delete pThrRecord;
改为
if(pThrRecord)]
{
TerminateThread(pThrRecord->m_hThread);
delete pThrRecord;

}
