Important Update
With this source code sample you may quickly learn how to record screen video from given region in C++ (managed). ByteScout Screen Capturing SDK is the screen video recording SDK helps in quick implementation of screen video recording. WMV, AVI, WebM output options are available with adjustable quality, video size, framerate and video and audio codec. Includes special features like live multiple blacking out of selected areas, recording from web cam as main source and as overlay, optional watermarks for output video and you can use it to record screen video from given region with C++ (managed).
This code snippet below for ByteScout Screen Capturing SDK works best when you need to quickly record screen video from given region in your C++ (managed) application. In your C++ (managed) project or application you may simply copy & paste the code and then run your app! Further enhancement of the code will make it more vigorous.
ByteScout Screen Capturing SDK free trial version is available on our website. C++ (managed) and other programming languages are supported.
