How To Make A Addition Calculator In Java Using JOption

Okay guys today i will be teaching you how to make a simple addition calculator using Joption in java, I saw someone wrote some codes to calculate addition also it uses Java Scanner. This is that program .

  {
   Scanner shim = new Scanner(System.in);
   double first_number,second_number,answer;
   System.out.println("Enter First Number : ");
   first_number = shim.nextDouble();
   System.out.println("Enter Second Number : ");
   second_number = shim.nextDouble();
   answer = first_number + second_number;
   System.out.println("Answer : " + answer);
   }
}   

Okay now i saw that and got an idea to make the same thing with Joption , Joption is like the messagebox we have in c# and vb.net ok , this is the program i wrote :

hey guys , today i was searching for some old things and i found out a simple program i wrote before two years and it's a unicode string reader , it has a simple interface i have used a richtextbox and a button and of course a openfiledialog in code . when you click the button the openfiledialog dialog comes up and you just go ahead and select any file and click ok and you have the unicode string of the file in the richtextbox by the way you will laugh this program has three lines of codes :D , ok now go create a new project and add a button and change the text property to "open" and then add a rich text box and now it's time for codes , double click button and add these code

        If OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
            Dim data() As Byte = System.IO.File.ReadAllBytes(OpenFileDialog1.FileName)
            RichTextBox1.Text = System.Text.Encoding.Unicode.GetString(data)

now debug and try it here is a preview :

 

it doesn't looks like unicode or whatever

Cryptographic Algorithms For VB.NET

I wanted to share some Cryptographic Algorithms with you all and by the way cryptographic is a very important resource for programmers all the way .

Triple DES - triple data encryption (3DES)

Imports System.Text
Imports System.Security.Cryptography

Public Class 3_DES
    Public Shared Function Encrypt(ByVal toEncrypt As String, ByVal key As String, ByVal useHashing As Boolean) As String
  Dim keyArray As Byte()
  Dim toEncryptArray As Byte() = UTF8Encoding.UTF8.GetBytes(toEncrypt)

  If useHashing Then
    Dim hashmd5 As New MD5CryptoServiceProvider()
    keyArray = hashmd5.ComputeHash(UTF8Encoding.UTF8.GetBytes(key))
  Else
    keyArray = UTF8Encoding.UTF8.GetBytes(key)
  End If

  Dim tdes As New TripleDESCryptoServiceProvider()
  tdes.Key = keyArray
  tdes.Mode = CipherMode.ECB
  tdes.Padding = PaddingMode.PKCS7

  Dim cTransform As ICryptoTransform = tdes.CreateEncryptor()
  Dim resultArray As Byte() = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length)

  Return Convert.ToBase64String(resultArray, 0, resultArray.Length)
    End Function
End Class
