mfc, Program Fail to Run After Convert from VC++ 6.0 to VC++ .NET 2003

I got a VC++ 6.0 program which is a windows service. After converting to VC++
.NET 2003 project and fixing some coding error. It can compile and looks work
fine. But when I run the service, it said program error and looks it cannot
get a thread from AfxGetThread function.

Below please find a code segment which I experience the error.

Any can help on this?


const CString NDSApp::SERV_NAME(_T("NDS Data Delivery"));

NDSApp::NDSApp()
:CNTService("NDS Data Delivery"){
m_pNDSSetting = new CRegKeyValuePair(APPNAME,SECTION);
}

NDSApp::~NDSApp()
{
if (m_pNDSSetting)
delete m_pNDSSetting;

//if (m_pMainWnd)
// delete m_pMainWnd;
}

// DO NOT EDIT what you see in these blocks of generated code!
//}}AFX_MSG
