Weird error with my code???

[ROFLMAO PiZZA]

Here is a PIECE of my code, not the whole thing

Private Sub label4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label4.Click
        Dim serial As String
        Dim length As Integer
        Dim byteArray() As Byte

        Dim badboy1 = 0
        Dim badboy2 = 0
        Dim badboy3 = 0
        Dim badboy4 = 0
        Dim seriall



        length = TextBox1.TextLength
        If length < 6 Then
            MsgBox("Name must have 6 letters! Closing to prevent patching in a debugger :P", MsgBoxStyle.Information)
            Me.Close()
        ElseIf length = 6 Or length > 6 Then

            serial = ""

            serial = serial & TextBox1.Text.Chars(3)
            serial = serial & TextBox1.Text.Chars(5)

            byteArray = System.Text.ASCIIEncoding.ASCII.GetBytes(serial)
            For i As Integer = 0 To byteArray.Length - 1
                serial = serial + byteArray(i).ToString("x")
            Next



            serial = serial.ToUpper
            Dim xxx = serial

            If TextBox2.Text = serial Then
                badboy = 0
            Else
                badboy = 1
                If badboy = 1 Then
                Else

                    badboy = 1

                    MsgBox("Incorrect serial! Make sure all letters are capitalized!")
                    badboy1 = 1
                    badboy2 = 1
                    badboy3 = 1

                    MsgBox(serial)
                End If
            End If

        End If

        If badboy = 0 Then
            seriall = ""

            seriall = seriall & TextBox1.Text.Chars(4)
            seriall = seriall & TextBox1.Text.Chars(0)
            seriall = seriall & TextBox1.Text.Chars(1)

            byteArray = System.Text.ASCIIEncoding.ASCII.GetBytes(seriall)
            For ilaw As Integer = 0 To byteArray.Length - 1
                seriall = seriall + byteArray(ilaw).ToString("x")
            Next



            seriall = seriall.ToUpper
            ilaw = 0

            If TextBox3.Text = seriall Then
                ilaw = ilaw + 1
            Else
                If badboy = 1 Then

                Else
                    badboy = 1
                    badboy1 = 1
                    badboy2 = 1

                    MsgBox("Incorrect seriall! Make sure all letters are capitalized!")
                    badboy3 = 1
                    MsgBox(seriall)

                    badboy4 = 1
                End If
            End If

            If badboy = 0 Then

            End If
        End If
    End Sub

It is for a shareware program, but when i click on label 4, it freezes. If you want the full thing, i can give it to you, but it will be stripped of most things. Thanks in advance
PS. the badboy1 - 4 are so debuggers get messed up, and can't serial phish.

Hi... Welcome to the forums...

Add a Breakpoint on the "Next" statement and run it. Then check the value of "byteArray.Length". See if it is larger or not. If it is much larger, then that's the problem for frozen window. You have to either modify it to perform correctly (if you are not expecting a bigger value there) or try adding Application.DoEvents() line inside the loop.

Ok did that, but the validation is messed up. It just wont work, here is my code now.

   Private Sub label4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label4.Click
        Dim serial As String
        Dim length As Integer
        Dim byteArray() As Byte
        Dim badboy = 0
        Dim badboy1 = 0
        Dim badboy2 = 0
        Dim badboy3 = 0
        Dim badboy4 = 0
        Dim seriall
        Dim letters = 6


        length = TextBox1.TextLength
        If length < 6 Then
            badboy = 1
            MsgBox("Name must have " & letters & " letters!", MsgBoxStyle.Information)
        ElseIf length = 6 Or length > 6 Then

            If badboy = 1 Then

            Else
                serial = ""

                serial = serial & TextBox1.Text.Chars(3)
                serial = serial & TextBox1.Text.Chars(5)


                byteArray = System.Text.ASCIIEncoding.ASCII.GetBytes(serial)
                serial = ""
                For i As Integer = 0 To byteArray.Length - 1
                    serial = serial + byteArray(i).ToString("x")
                Next

                serial = serial.ToUpper

                If TextBox2.Text = serial Then
                    badboy = 0
                Else
                    badboy = 1
                    If badboy = 1 Then
                    Else

                        badboy = 1

                        MsgBox("Incorrect serial! Make sure all letters are capitalized!")
                        badboy1 = 1
                        badboy2 = 1
                        badboy3 = 1

                        MsgBox(serial)
                    End If
                End If

        End If



        If badboy = 0 Then
            seriall = ""

            seriall = seriall & TextBox1.Text.Chars(4)
            seriall = seriall & TextBox1.Text.Chars(0)
            seriall = seriall & TextBox1.Text.Chars(1)

                byteArray = System.Text.ASCIIEncoding.ASCII.GetBytes(seriall)
                serial = ""
            For ilaw As Integer = 0 To byteArray.Length - 1
                seriall = seriall + byteArray(ilaw).ToString("x")
            Next



            seriall = seriall.ToUpper
            ilaw = 0

            If TextBox3.Text = seriall Then
                ilaw = ilaw + 1
            ElseIf badboy = 1 Then


                        badboy = 1
                        badboy1 = 1

I don't know how it works or what you are expecting !

I just trimmed off the extra code and tested the main part:

Private Sub Label4_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label4.Click
        Dim serial As String
        Dim length As Integer
        Dim byteArray() As Byte
 
        length = TextBox1.TextLength
        If length < 6 Then
            MsgBox("Name must have 6 letters! Closing to prevent patching in a debugger :P", MsgBoxStyle.Information)
            Me.Close()
        ElseIf length >= 6 Then
 
            serial = TextBox1.Text.Chars(3) & TextBox1.Text.Chars(5)
 
            byteArray = System.Text.ASCIIEncoding.ASCII.GetBytes(serial)
 
            For i As Integer = 0 To byteArray.Length - 1
                serial = serial & byteArray(i).ToString("x")
            Next
 
            serial = serial.ToUpper
 
            If TextBox2.Text = serial Then
                MessageBox.Show("Congratz! You have unlocked the product")
            Else
                MessageBox.Show("Hmm... Doesn't match ! The code is: " & serial)
            End If
        End If
    End Sub

Are you expecting the same ?
