Log messages listenning in .NET

Yes, I'm not an c# expert with testcomplete but I think this will work. if not please dm me we can investigate this further 

using System;
using TestCompleteIntegrationNamespace; // Replace with the actual namespace of your TestCompleteIntegration library

public class TestCompleteIntegrationObject
{
    private ITestCompleteCOMManager TestCompleteManager;
    private ItcIntegration IntegrationObject;
    private object TestCompleteObject;
    private const string TCProgID = "TestComplete.TestCompleteApplication.14";

    public TestCompleteIntegrationObject()
    {
        this.InitializeTcObject();
        if (IntegrationObject != null)
        {
            // Subscribe to integration events
            IntegrationObject.OnLogMessage += IntegrationObject_OnLogMessage;
            IntegrationObject.OnWarningMessage += IntegrationObject_OnWarningMessage;
            IntegrationObject.OnError += IntegrationObject_OnError;
            IntegrationObject.OnInfoMessage += IntegrationObject_OnInfoMessage;
        }
    }

    public void InitializeTcObject()
    {
        try
        {
            TestCompleteObject = Marshal.GetActiveObject(TCProgID);
        }
        catch
        {
            try
            {
                TestCompleteObject = Activator.CreateInstance(Type.GetTypeFromProgID(TCProgID));
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                Console.WriteLine("Unable to initialize TestComplete.");
            }
        }

        if (TestCompleteObject != null)
        {
            TestCompleteManager = (ITestCompleteCOMManager)TestCompleteObject;
            IntegrationObject = TestCompleteManager.Integration;
        }
    }

    private void IntegrationObject_OnLogMessage(string message)
    {
        // Handle log message here
        // You can collect and format the messages as needed
    }

    private void IntegrationObject_OnWarningMessage(string message)
    {
        // Handle warning message here
    }

    private void IntegrationObject_OnError(string message)
    {
        // Handle error message here
    }

    private void IntegrationObject_OnInfoMessage(string message)
    {
        // Handle info message here
    }
}
