How to write event log(Event Viewer) using C++ - 用C++如何写事件日志（事件查看器）

//Defination
static bool WriteEventLog(LPCTSTR szEventMsg,WORD wEventType = NULL,LPCTSTR szSourceName = "");

bool CPrjReadWriteEventViewerDlg::WriteEventLog(LPCTSTR szEventMsg, WORD wEventType, LPCTSTR szSourceName)
{
	HANDLE hEventLog;
	bool bSuccesful;
	bool bReturn = true;
	//-------------------------------------------------------------------------

	if("" == szSourceName)
	{
		szSourceName = AfxGetApp()->m_pszExeName;
	}
	

	hEventLog = RegisterEventSource(NULL,szSourceName);
	if(NULL == hEventLog)
	{
		AfxMessageBox("RegisterEventSource Failed");
		return false;
	}
	
	bSuccesful = ReportEvent(hEventLog,
							 wEventType,
							 NULL,
							 NULL,
							 NULL,
							 1,
							 0,
							 &szEventMsg,
							 NULL);
	
	if(false == bSuccesful)
	{
		AfxMessageBox("ReportEvent Failed");
		bReturn = false;
	}
	
	DeregisterEventSource(hEventLog);

	return bReturn;

}

//Invoke Method
void CPrjReadWriteEventViewerDlg::OnLButtonDblClk(UINT nFlags, CPoint point) 
{
	// TODO: Add your message handler code here and/or call default
	
	WriteEventLog("sdfsdfdsfdsfeeedcd");
	WriteEventLog("sdfsdfdsfdsfeeedcd",NULL,"eeeeeeeeee");
	WriteEventLog("sdfsdfdsfdsfeeedcd",EVENTLOG_SUCCESS,"seeee");
	WriteEventLog("sdfsdfdsfdsfeeedcd",EVENTLOG_AUDIT_FAILURE,"seeee");
	WriteEventLog("sdfsdfdsfdsfeeedcd",EVENTLOG_AUDIT_SUCCESS,"seeee");
	WriteEventLog("sdfsdfdsfdsfeeedcd",EVENTLOG_ERROR_TYPE,"seeee");
	WriteEventLog("sdfsdfdsfdsfeeedcd",EVENTLOG_INFORMATION_TYPE,"seeee");
	WriteEventLog("sdfsdfdsfdsfeeedcd",EVENTLOG_WARNING_TYPE,"seeee");


	CDialog::OnLButtonDblClk(nFlags, point);
