Here everything is in Main Program itself. But i want it all in a seperate class Nmaed PrimeNumClass.cs and i have to call that class in the main Class to display the output.

using System;
using System.Collections.Generic;
using System.Text;
 
namespace PrimeNumber
{
    class PrimeNumClass
    {
    }
}

but what are all the things have to be inside that class and let me know it by code.

becoz i have the output in the main program and all the funcctions are carried out there. but i have been asked that in the main program there should not be anything but we have to create the object and w ehave to call that method to display the output of the prime number.

namespace ClassDemo
{
    public class MyClass
    {
    }
}

namespace ClassDemo
{
    public class MyClass
    {
        public void SayHello()
        {
            Console.WriteLine("Hello!");
        }
    }
}

MyClass mc = new MyClass();
 
mc.SayHello();

Will the main form process the first packet completely before it processes the second?

Do I have to add some blocking to the serial thread so that it doesn't send a packet for
processing when another is being processed.

I am having problems figuring out how this should be done.. for instance if part 1 is checking every minute by using a timer if parts 2 - 4 haven't completed after part 1 has notified them the first time it might try to notify about the same records again

Why do you stream.Write()?

I also don't understand why you set bmp = null

Also, you don't say where the errors occurred

public static Bitmap BytesToBmp( byte[] b )
{
    using ( MemoryStream ms = new MemoryStream(b , true) ) 
    {
	Bitmap bmp = Bitmap.FromStream( ms ) as Bitmap;
	return bmp;
