    FlushFinalBlock() method was called twice on a CryptoStream

    I am getting the following message and no, it is not even going to that
    statement twice. Why is this happening?


    System.NotSuppo rtedException was caught
    Message="FlushF inalBlock() method was called twice on a CryptoStream. It
    can only be called once."
    Source="mscorli b"
    StackTrace:
    at System.Security .Cryptography.C ryptoStream.Flu shFinalBlock()
    at TempCrypt.Crypt .DecryptString1 28Bit(String
    vstrStringToBeD ecrypted, String vstrDecryptionK ey) in
    D:\Projects\VB\ TempCrypt\TempC rypt\Crypt.vb:l ine 132

    TIA,

      Well, we would need to see the snippit of code that generates the error to be
      sure.

          Sorry, I meant to add this, here is the code that generates the error.

          bytDataToBeDecr ypted = Convert.FromBas e64String(vstrS tringToBeDecryp ted)
          bytDecryptionKe y = Encoding.ASCII. GetBytes(vstrDe cryptionKey.ToC harArray)
          ReDim bytTemp(bytData ToBeDecrypted.L ength)
          objMemoryStream = New MemoryStream(by tDataToBeDecryp ted)
          objCryptoStream = New CryptoStream(ob jMemoryStream,
          objRijndaelMana ged.CreateDecry ptor(bytDecrypt ionKey, bytIV),
          CryptoStreamMod e.Read)
          objCryptoStream .Read(bytTemp, 0, bytTemp.Length)
          Try
          objCryptoStream .FlushFinalBloc k() <-- It goes to the Catch statement from
          here
          objMemoryStream .Close()
          objCryptoStream .Close()
          Catch ex As Exception
          MsgBox("Decrypt String: " & ex.ToString)
          End Try

          Thanx,
