"Coder" Program

Post icon  Posted 19 December 2008 - 03:05 PM

I'm working on a program called Coder. Before you read the code, here are the instructions for the program: " Create a Coder application that encodes and decodes a message using Unicode.
BTY: You advance programmers should already be aware of Unicode

 Public Class Form1
	Dim strMessage As String
	Dim strCodedMessage As String

	Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGo.Click
		If radEncode.Checked = True Then
			strMessage = txtInput.Text

			If strMessage = Nothing Then
				MsgBox("Please enter a message to decode")
			Else
				For intNum As Integer = 0 To (strMessage.Length - 1)
					If strMessage.Chars(intNum) = "Y" Then
						strCodedMessage = strCodedMessage & "A" & " "
					ElseIf strMessage.Chars(intNum) = "Z" Then
						strCodedMessage = strCodedMessage & "B" 7 " "
					Else
						strCodedMessage = strCodedMessage & ChrW(AscW(strMessage.Chars(intNum)) + 2)
					End If
				Next
			End If
		End If
		txtInput.Text = strCodedMessage

		strMessage = Nothing
		strCodedMessage = Nothing
		ElseIf radDecode.Checked = True Then
		strCodedMessage = txtInput.Text

		strCodedMessage.Trim(" ")
		strCodedMessage = strCodedMessage.PadRight(strCodedMessage.Length + 1)

		Dim intMax As Integer = strCodedMessage.Length - 1

		For intNum As Integer = 0 To intMax
			If strCodedMessage = "" Then

				If strCodedMessage.Chars(intNum) = "A" Then
					strMessage = strMessage & "Y"
					strCodedMessage = strCodedMessage.Remove(0, intNum + 1)
				ElseIf strCodedMessage.Chars(intNum) = "B" Then
					strMessage = strMessage & "Z"
					strCodedMessage = strCodedMessage.Remove(0, (intNum + 1))
				Else
					Dim strVar As String

					For intNum2 As Integer = 0 To (intNum)
						strVar = strVar & AscW(strCodedMessage.Chars(intNum2))
					Next
					Dim intVar = Val(strVar) - 2

					strMessage = strMessage & ChrW(intVar)

					strCodedMessage = strCodedMessage.Remove(0, 1)
					strVar = Nothing
				End If
				intNum = -1
				intMax = strCodedMessage.Length - 1
			End If
		Next

		txtInput.Text = strMessage

		strMessage = Nothing
		strCodedMessage = Nothing
	End Sub

	Private Sub EncodeToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles EncodeToolStripMenuItem.Click
		radEncode.Enabled = True
	End Sub

		End If
	End Sub

	Private Sub ExitToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ExitToolStripMenuItem.Click

End Class

It won't run and there are 2 erros.
Error #1 says: "End of statement expected". It is this line right here 
ElseIf strMessage.Chars(intNum) = "Z" Then 
						strCodedMessage = strCodedMessage & "B" 7 " "
It's those quotation marks (line 16, columm 65)
Error #2 says: ElseIf must be preceded by a matching "If" or ElseIf". It is this line right here 
 ElseIf radDecode.Checked = True Then
(line 27, column 9)

Looks liek you type a '7' instead of a '&' to concat the strings...

strCodedMessage = strCodedMessage & "B" & " " 'You need to replace that 7 with an &

Oh yeah, thanks. Now I fixed the "ElseIf" error but now I can't type anything in the textbox. Do you know why?

You're going to have to tell us what your program is supposed to do and what errors you're getting. We're not mind readers.

Oh yeah sorry lol. I posted another post with the instructions, i just suppossed that you already read it.

Ok here are instructions: "Create a Coder application that encodes or decodes a messagge using Unicode."
So basically you type something in a textbox and then you click on an encode radio button or decode radio button and it will encode it from regular words to unicode. For decode you type in unicode and it turns it back into regular words.
And I'm not getting an error it just won't do anything
(I couldn't attatch the actual program to this post, it wouldn't let me)

My program is called Coder (which many of you already know). Directions: Create a Coder application that encodes and decodes a message using Unicode.

Now I fixed the error but it still won't do anything. Can someone tell me why?

Public Class Form1

						strCodedMessage = strCodedMessage & "A" & " "
					ElseIf strMessage.Chars(intNum) = "Z" Then

Please, you have started three threads regarding the same exact program, same exact questions, same exact code. Opening thread after thread isn't going to get you help any faster, all it's going to do is clutter the forum, and confuse those who are trying to help. Please do not start another thread regarding this issue :)
