' Set the length in bytes of the input file

'    MessageBox.Show("Original length: " & New System.IO.FileInfo(filePath)
' .Length)
'    SetFileLength(filePath, 50000)
'    MessageBox.Show("New length: " & New System.IO.FileInfo(filePath).Length)

Sub SetFileLength(ByVal filePath As String, ByVal sizeInBytes As Long)
    Dim fs As System.IO.FileStream

    Try
        fs = New System.IO.FileStream(filePath, IO.FileMode.Open)
        fs.SetLength(sizeInBytes)
    Finally
        If Not fs Is Nothing Then fs.Close()
    End Try
