Screen recording of a region around the mouse ready-to-use code sample:

This sample code demonstrates how to use Screen Capturing SDK to record video from the dynamic region around the mouse. The region is defined by the width and height. This method works as a virtual camera that follows to the mouse cursor.

1) Visual Basic .NET

Create new VB.NET Console project in Visual Studio. Click Project | Add Reference.. and add the reference to Bytescout Screen Capturing Lib on the COM tab and click OK. Then use the code snippet below:

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.catMouse

  ' output video filename

    capturer.OutputFileName = "RegionAroundMouseCaptured.avi"



    ' set width and height of the rectangle around the mouse to capture video from

    capturer.CaptureRectWidth = 320

    capturer.CaptureRectHeight = 240



  ' start capturing

    capturer.Run()



    ' wait for 15 seconds

    Thread.Sleep(15000)



  ' stop capturing and flush AVI video file into the disk

    capturer.Stop()



    ' open the output video

    Process.Start("RegionAroundMouseCaptured.avi")



  End Sub



End Module

2) Visual C# .NET

Create new C# Console project in Visual Studio. Click Project | Add Reference.. and add the reference to Bytescout Screen Capturing Lib on the COM tab and click OK. Then use the code snippet below:

using System;

using System.Collections.Generic;

using System.Text;

using System.Threading;

using System.Diagnostics;



using BytescoutScreenCapturingLib; // import bytescout screen capturing activex object



namespace SimpleCaptureCSharp

{

  class Program

  {

    static void Main(string[] args)

    {

      CapturerClass capturer = new CapturerClass(); // create new screen capturer object



      capturer.CapturingType = CaptureAreaType.catMouse; // set capturing area type to catScreen to capture whole screen



      capturer.OutputFileName = "EntireScreenCaptured.avi"; // set output video filename



    // set width and height of the region around the mouse

    capturer.CaptureRectWidth = 320

    capturer.CaptureRectHeight = 240



      // set output video width and height

      capturer.OutputWidth = 320;

      capturer.OutputHeight = 240;



      capturer.Run(); // run screen video capturing



      Thread.Sleep(15000); // wait for 15 seconds



      capturer.Stop(); // stop video capturing



      Process.Start("EntireScreenCaptured.avi");

    }

  }

}

2) Visual Basic 6 and VBScript (VBS)

' create video capturer activex object

Set capturer = CreateObject("BytescoutScreenCapturing.Capturer")



' set output video file name

capturer.OutputFileName = "RegionAroundMouseCaptured.avi"



' set capturing type to the caMouse =2 to capture the region around the mouse curosr. You can also set to caRegion = 0 (to record from the given rectangle on screen) or to caScreen = 3 (to capture entire screen)

capturer.CapturingType = 2



' set width of the rectangle to capture from

capturer.CaptureRectWidth = 320

' set height of the rectangle to capture from

capturer.CaptureRectHeight = 240



MsgBox "Script will record 320x240 region around the mouse cursor for 10 seconds. Output video will go to CaptureScreenVbs.avi"



' run video capturing

capturer.Run()



' wait for 10 seconds (10000 msec)

WScript.Sleep(10000)



' stop capturing

capturer.Stop()



' destroy Capturer object so the video will be saved into the disk

Set capturer = Nothing
