Imports System.Threading
Imports System.Diagnostics

Imports BytescoutScreenCapturingLib ' import bytescout screen capturer activex object

Module Module1

    Sub Main()
    ' create capturer class
        Dim capturer As New CapturerClass()
    ' set capturing area to the region type (to capture from given region on the screen)
        capturer.CapturingType = CaptureAreaType.catScreen
    ' output video filename to .WMV or .AVI
        capturer.OutputFileName = "EntireScreenCaptured.wmv"

        ' set width and height of output video
        capturer.OutputWidth = 640
        capturer.OutputHeight = 480

      ' uncomment to set Bytescout Lossless Video format output video compression method
    ' do not forget to set file to .avi format if you use Video Codec Name
        ' capturer.CurrentVideoCodecName = "Bytescout Lossless"           


        ' start capturing
        capturer.Run()

        ' wait for 25 seconds
        Thread.Sleep(25000)

        ' stop capturing and flush AVI video file into the disk
        capturer.Stop()

        ' open the output video 
        Process.Start("EntireScreenCaptured.avi")

    End Sub
