    void DoSampleTest()
    {
        string deviceString = "$logfile:file=WTTLOGTest.xml,Writemode=overwrite";
        m_Logger = new WttLogger(deviceString);
 
        // Start a test case
        m_Logger.StartTest("Test 1 - Testing Tracing functions");
 
        m_Logger.Trace(new LevelError(0x3,ErrorType.Win32,"break"));
        // Trace machine info
        m_Logger.TraceMachineInfo();
 
        // Trace a message by using a message string
        m_Logger.Trace(new LevelMessage("Testing Tracing Messages"));
 
        // Trace a message by using a user object only
        Test1 userObject = new Test1();
        m_Logger.Trace(new LevelMessage(userObject));
 
        // Trace a message by using a user object and a message string
        m_Logger.Trace(new LevelMessage("Testing Tracing Messages with user Objects",userObject));
 
        // Trace a normal error
        m_Logger.Trace(new LevelError(0x3,ErrorType.Win32,
            "Testing Tracing Errors"));
 
        try
        {
            // Generate IOException
            File.Open("c:\toot.txt",FileMode.Open,FileAccess.Read,FileShare.Read);
        }
        catch(Exception exp)
        {
            // Trace an exception error
            m_Logger.Trace(new LevelError(exp));
        }
        // End test case
        m_Logger.EndTest("Test 1 - Testing Tracing functions",0,null);
