Thanks in advanced.


private void Encrypt()
                        System.IO.FileInfo finfo=new System.IO.FileInfo(inFile);
**1**                        progressBar.Maximum=(int)(finfo.Length/32);

                        System.IO.FileStream fout=System.IO.File.Open(outFile,System.IO.FileMode.Create,System.IO.FileAccess.Write,System.IO.FileShare.Write);
                        System.IO.FileStream fin=System.IO.File.Open(inFile,System.IO.FileMode.Open,System.IO.FileAccess.Read,System.IO.FileShare.Read);
**2**                        byte []buffer=new byte[32];
**3**                        byte []encbuffer=new byte[32];
                        int c=0;
*****                        while((c=fin.Read(buffer,0,32))>0)

This is the result of passing the code through the utility at:

Private Sub Encrypt()
   progressBar.Minimum = 0
   Dim finfo As System.IO.FileInfo = New System.IO.FileInfo (inFile)
   progressBar.Maximum = CType((finfo.Length / 32), Integer)
   lblStatus.Text = "Encrypting..."
   Dim fout As System.IO.FileStream = System.IO.File.Open(outFile, System.IO.FileMode.Create, System.IO.FileAccess.Write, System.IO.FileShare.Write)
   Dim fin As System.IO.FileStream = System.IO.File.Open(inFile, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.Read)
   Dim buffer(32) As Byte
   Dim encbuffer(32) As Byte
   Dim c As Integer = 0
   While (c = fin.Read(buffer, 0, 32)) > 0
     If Not (c = buffer.Length) Then
       Dim buffer2(c) As Byte
       Dim i As Integer = 0
       While i < c
         buffer2(i) = buffer(i)
         i += 1
       End While
       encbuffer = rsa.Encrypt(buffer2, False)
       fout.Write(encbuffer, 0, encbuffer.Length)
       encbuffer = rsa.Encrypt(buffer, False)
       fout.Write(encbuffer, 0, encbuffer.Length)
     End If
   End While
   lblStatus.Text = "Encryption successful"
 Catch ex As Exception
   MessageBox.Show("Error:" + ex.Message)
 End Try
End Sub
