Simple use of MFC multithreading

int main()

	thread1.m_bAutoDelete=false;// Automatically destroy objects when the thread ends 
	thread1.CreateThread();// Create thread 
	WaitForSingleObject(thread1.m_hThread,INFINITE);// Wait for the thread to finish executing 
return 0;
}

// Thread execution function 
UINT CreateLoginDlg(LPVOID Param)
{
    
	CLoginDlg *dlg=new CLoginDlg;
	dlg->Create(IDD_DIALOG_LOGIN,NULL);
	dlg->ShowWindow(SW_SHOW);
