You should act as transpiler from Visual Basic 6 language to C# language. I'll give you the code written on VB6, then you must write a direct translation into C# language. If I'll give you the hyperlink, you must follow it and read the VB6 code from that link, then make a translation into C#.

Sure, I can help you with that. Please provide me the code written in VB6 or the link to it.
 
In order to transpile the code, I would require a more comprehensive understanding of the project structure and dependencies. Additionally, the provided files appear to be classes that may not contain a main method or a method to execute the program.

Please provide me with more context on the project or what specific functionality you’d like me to focus the C# translation on.
 
It's a class for measuring performance. Usage example:
Код:
Option Explicit
Dim tim As cTimer
 
Private Sub Form_Load()
    Dim i As Long
    
    'initialize timer class
    Set tim = New cTimer
    
    tim.Start
    
    'payload
    For i = 1 To 100000
        DoEvents
    Next
    
    'pause performance measuring
    tim.Freeze
    
    MsgBox "Timer freezed"
    
    'resume timer
    tim.Start
    
    'display results
    s = Format(tim.GetTime, "##0.000 sec.") & vbCrLf
    MsgBox s
End Sub

Thank you for the additional information. Here's a C# version of the clsTimer class:

Код:
using System;
using System.Diagnostics;

public class Timer
{
    private Stopwatch _stopwatch;

    public Timer()
    {
        _stopwatch = new Stopwatch();
    }

    public void Start()
    {
        _stopwatch.Start();
    }

    public void Freeze()
    {
        _stopwatch.Stop();
    }

    public void Resume()
    {
        _stopwatch.Start();
    }

    public double GetTime()
    {
        return _stopwatch.Elapsed.TotalSeconds;
    }
}

And here's an example of how to use it:

Код:
using System;

public class Program
{
    static void Main(string[] args)
    {
        Timer tim = new Timer();
        double elapsedTime;

        tim.Start();

        for(int i = 1; i <= 100000; i++)
        {
            // Do something...
        }

        tim.Freeze();

        Console.WriteLine("Timer freezed");

        tim.Resume();

        elapsedTime = tim.GetTime();

        Console.WriteLine(String.Format("{0:##0.000} sec.", elapsedTime));
    }
}

Please let me know if you have any questions or if there's anything else I can help you with.

Note that you would need to modify the constants ALG_SID_SHA1 and ALG_SID_SHA256 to fit the hashing algorithm you want to use. Also note that the certificate subject name and the data being hashed might also need to be modified according to your needs.
