Great, a .NET KeygenMe.
Code:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
    Try
        Dim str6 As String
        Dim text As String = Me.TextBox2.Text
        Dim des2 As New Simple3Des(Me.TextBox1.Text)
        Dim str3 As String = ""
        Dim str7 As String = ""
        Try
            str7 = des2.DecryptData([text])
            If (str7 = Me.TextBox4.Text) Then
                goto Label_0085
            End If
            Interaction.MsgBox("Wrong security question!", MsgBoxStyle.OkOnly, Nothing)
        Catch exception1 As CryptographicException
            ProjectData.SetProjectError(exception1)
            Dim exception As CryptographicException = exception1
            Interaction.MsgBox("Wrong Name/Serial!", MsgBoxStyle.OkOnly, Nothing)
            ProjectData.ClearProjectError
        End Try
        Return
    Label_0085:
        str6 = Me.TextBox1.Text
        Dim key As String = str7
        str3 = New Simple3Des(key).EncryptData(str6)
        If (Me.TextBox3.Text = str3) Then
            Interaction.MsgBox("Correct info!", MsgBoxStyle.OkOnly, Nothing)
        Else
            Interaction.MsgBox("Wrong info!", MsgBoxStyle.OkOnly, Nothing)
        End If
    Catch exception3 As Exception
        ProjectData.SetProjectError(exception3)
        Dim exception2 As Exception = exception3
        Interaction.MsgBox("Wrong Name/Serial!", MsgBoxStyle.OkOnly, Nothing)
        ProjectData.ClearProjectError
    End Try
End Sub

Symbol, did you know that because it had the .NET icon or some other method? If some other method, could you elaborate?

Anyone know Why OllyDBG doesnt find any strings related to the program?

I'd like to try cracking it, but it doesnt help if the program hides its strings from olly 0.0

Looking into it, olly does this with everything .net <.<

Learn what .NET is. Don't think strings will save you for everything.

About all I know is it converts all of the data to byte code, kinda like a scripted language such as python.

But even so, the strings being used should be saved in the executable shouldn't they?
