Math Problem With Enum

[iccaros]

ok I have a math problem I can not find

here is the code

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace Basic_Encrytion
{
	//The ideal behind this encryption is to mimic the EMIGMA machines of WWII. With the use of diffrent random wheels
	//you can create a good enough encrytion, by adding the modifier you are chaning the starting position of the wheel
	//Encryption Wheels declaration
	public enum WheelOne  : int
	{ a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z,
	  A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z }
	public enum WheelTwo : int
	{ Z, Y, X, W, V, U, T, S, R, Q, P, O, N, M, L, K, J, I, H, G, F, E, D, C, B, A, 
	  z, y, x, w, v, u, t, s, r, q, p, o, n, m, l, k, j, i, h, g, f, e, d, c, b, a }
	public enum WheelThree : int
	{ a, c, e, g, i, k, m, o, q, s, u, w, y, A, C, E, G, I, K, M, O, Q, S, U, W, Y,
		b, d, f, h, j, l, n, p, r, t, v, x, z, B, D, F, H, J, L, N, P, R, T, V, X, Z }
	public partial class Form1 : Form
	{

		  //variable declaration 
		  public string DisplayEncrypt = "";
		  public string DisplayDecrypt = "";


		  public string encrypt(char RedSideIn, int WheelPosition,int WheelNumber)
		  {

			 int BlackSideInt = 0;
			 int RedSideInStr = (int) Enum.Parse(typeof(WheelOne),Convert.ToString(RedSideIn));
			 string BlackSideOut = "";
			 //ensure the pattern loops
			 if (WheelPosition + RedSideInStr > 51) 
				 BlackSideInt = (WheelPosition + RedSideInStr) - (52);
			 else if (WheelPosition + RedSideInStr < 0)
				 BlackSideInt = (WheelPosition + RedSideInStr) + (52);
			 else   
			  BlackSideInt = WheelPosition + RedSideInStr;

			 if (WheelNumber == 1)
				 BlackSideOut = Wheel1(BlackSideInt);
			 else if (WheelNumber == 2)
				 BlackSideOut = Wheel2(BlackSideInt);
			 else if (WheelNumber == 3)
				 BlackSideOut = Wheel3(BlackSideInt);

			  return BlackSideOut;

		  }

		private string Wheel3(int BlackSideInt)
		{
			WheelThree letter = (WheelThree)BlackSideInt;
			return letter.ToString("G");
		}

		private string Wheel2(int BlackSideInt)
		{
			WheelTwo letter = (WheelTwo)BlackSideInt;
			return letter.ToString("G");
		}

		public string Wheel1(int BlackSideInt)
		{
			WheelOne letter = (WheelOne)BlackSideInt;
			return letter.ToString("G");
		}
		public Form1()
		{
			InitializeComponent();
		}

		private void button1_Click(object sender, EventArgs e)
		{

			//tokenize input to be sent to encryptor
		   string TokEncrypt = SourceBox.Text;
		   int WheelNumber = 0; 
			for (int x = 0;x < TokEncrypt.Length;x++)
			{
			  //  WheelNumber++;
			   // if (WheelNumber > 3)
			   //	 WheelNumber = 1;
				DisplayEncrypt = DisplayEncrypt + encrypt(TokEncrypt[x],25,2);

			}
			EncryptBox.Text = DisplayEncrypt;
			WheelNumber = 0;
			for (int x = 0; x < DisplayEncrypt.Length; x++)
			{
			   // WheelNumber++;
			   // if (WheelNumber > 3)
			   //	 WheelNumber = 1;
				DisplayDecrypt = DisplayDecrypt + encrypt(DisplayEncrypt[x], -25,2);

			}
			DecryptBox.Text = DisplayDecrypt;


			//clean up
			DisplayEncrypt = "";
			DisplayDecrypt = "";
			WheelNumber = 0;
		}
	}
}

if I choose wheel one it works

if I choose wheel 2 Y&Z and a&b are messed up

if I choose wheel 3 non of it works..

this should be simple pattern matching..

example I use wheel2 and put in abcdefghijklmnopqrstuvwxyz

this is it encrypted Azyxwvutsrqponmlkjihgfedcb

but this is the decrypt YZabcdefghijklmnopqrstuvwx

if I use wheel3 I get this

in: abcdefghijklmnopqrstuvwxyz

encrypt:YbdfhjlnprtvxzBDFHJLNPRTVX

decrypt:YfjnrvzDHLPTXaeimquyCGKOSW

thanks

here is the project file VS 2005 type

Basic_Encrytion.zip

fixed it, I noticed I was uisng WheelOne for all lookups, makes it hard for the others to decrypt..

here is the fixed code

		   int WheelNumber = 0; 
			for (int x = 0;x < TokEncrypt.Length;x++)
			{
			   WheelNumber++;
				if (WheelNumber > 3)
					WheelNumber = 1;
				DisplayEncrypt = DisplayEncrypt + encrypt(TokEncrypt[x],25,WheelNumber);

			}
			EncryptBox.Text = DisplayEncrypt;

			}
			DecryptBox.Text = DisplayDecrypt;


			//clean up
			DisplayEncrypt = "";
			DisplayDecrypt = "";
			WheelNumber = 0;
		}
	}
}

now does anyone have a better way?

I am thinking of advancing the wheelposition so
