How To Make A Simple Console Application In C#

this is a simple program to separate 6 digits from input, first you create string and name it (shim)  and you prompt the user to enter the number using console.write(); then you assign the user to input shim using the console.readline function so on you display each display/character using writeline , in this the argument comes after the comma in this argument

Console.WriteLine("First digit: {0}", shim.Substring(0,1));

shim.Substring(0,1) 

shim.substring(0,1) , when you use susbstring its going to read the string which is , the user input

console.readkey(); will keep the application awake

lets make the application , create a new project and select console application and name it whatever you want , add the codes below

using System;

namespace simple_console_application

{
        class Program

        {
                      static void Main(string[] args)

                {
                        string shim = "";

                        Console.Write("Enter a 6 digit Number: ");

                        shim = Console.ReadLine();

                        Console.WriteLine("First digit: {0}", shim.Substring(0,1));

                        Console.WriteLine("Second digit: {0}", shim.Substring(1, 1));

                        Console.WriteLine("Third digit: {0}", shim.Substring(2,1));

                        Console.WriteLine("Fourth digit: {0}", shim.Substring(3,1));

                        Console.WriteLine("Fifth digit: {0}", shim.Substring(4,1));

                        Console.WriteLine("Sixth digit: {0}", shim.Substring(5, 1));

                        Console.ReadKey();

How To Change Extensions In VB.NET

In this tutorial i'm going to tell you how to change file extensions.

     Dim type As String = ".mp4"
        MsgBox(TextBox1.Text + " is changed into a " + type + " file.")
        Dim oldFile As String = Mid(TextBox1.Text, 1, Len(TextBox1.Text) - 4)
        FileCopy(TextBox1.Text, oldFile + type)

How to use it:
You have a form containing: 2 buttons, 1 textbox (or combobox)
When you click button one you can say it must open a openfiledialog:

Dim ofd As New Openfiledialog
If ofd.showdialog = dialogresult.OK then
TextBox1.Text = ofd.filename
End If

If we click the button, a openfiledialog will appear and we can choose a file name and if we click on 'ok', then the textbox will contain the filename of the openfiledialog.
Now double click on the other button and fill in the code above.
That's it!
