Ciao, ho bisogno del vostro aiuto. Ho questo codice che nelle mie intenzioni vorrebbe utilizzare AxWindowsMediaPlayer1 per suonare un file mp3 appena decrittato (senza quindi riscrivere il file su disco). Ho cercato in internet ma non ho trovato nulla... Spero che qualcuno mi dia una mano!
La Form necessita di 3 Buttons, 1 Label, 1 Windows Media Player... e naturalmente occorre cambiare l'indirizzo del file mp3 di vostra scelta.
Questo e' il codice:
Codice sorgente - presumibilmente VB.NET |
Imports System.Security.Cryptography Imports System.IO Imports System.Text Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim rij As New RijndaelManaged() rij.KeySize = 256 rij.BlockSize = 256 rij.IV = New [Byte]() {24, 23, 35, 83, 77, 35, 28, 34, 94, 25, 45, 2, 73, 26, 27, 78, 12, 23, 35, 83, 57, 35, 28, 34, 94, 25, 45, 22, 73, 26, 27, 78} Dim pwd As Byte() = New Byte(31) {} UTF8Encoding.UTF8.GetBytes("123abc").CopyTo(pwd, 0) Dim cs As New CryptoStream (File. OpenRead("C:\Users\User\Desktop\aa.mp3"), rij.CreateEncryptor(pwd, rij.IV), CryptoStreamMode.Read) Dim s As Stream = File. OpenWrite("C:\Users\User\Desktop\bb.mp3") cs.CopyTo(s) s.Flush() s.Close() cs.Close() Label1.Text = "Criptato!" End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim rij As New RijndaelManaged() rij.KeySize = 256 rij.BlockSize = 256 rij.IV = New [Byte]() {24, 23, 35, 83, 77, 35, 28, 34, 94, 25, 45, 2, 73, 26, 27, 78, 12, 23, 35, 83, 57, 35, 28, 34, 94, 25, 45, 22, 73, 26, 27, 78} Dim pwd As Byte() = New Byte(31) {} UTF8Encoding.UTF8.GetBytes("123abc").CopyTo(pwd, 0) Dim mp3Bytes() As Byte Using cs As New CryptoStream (File. OpenRead("C:\Users\User\Desktop\bb.mp3"), rij. CreateDecryptor(pwd, rij. IV), CryptoStreamMode. Read) Using ms As New MemoryStream cs.CopyTo(ms) mp3Bytes = ms.GetBuffer End Using End Using Label1.Text = "Decriptato!" Clipboard.Clear() Clipboard.SetAudio(mp3Bytes) If Clipboard.ContainsAudio Then Dim btsFromClipboard() As Byte = {} Using cbstrm As Stream = Clipboard.GetAudioStream ReDim btsFromClipboard(CInt(cbstrm.Length) - 1) cbstrm.Read(btsFromClipboard, 0, CInt(cbstrm.Length)) End Using 'Ora vorrei farlo suonare direttamente dalla clipboard AxWindowsMediaPlayer1.Ctlcontrols.play() ' ???? Come si potrebbe risolvere? End If End Sub Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click End End Sub End Class
