Getting Started with Screen Video Capturing SDK

To view the documentation for the SDK go to Start > All Programs > Bytescout Screen Capturing SDK and click the “Documentation” link.

The SDK comes with lot of ready-to-use source code examples for Visual Basic, C#, VB6, VBScript.

To find source code samples please go to “My Documents” folder, “ByteScout Samples” and “Screen Capturing SDK”. Do not hesitate to copy and paste code snippets from samples right into your application!

The First Application

To help you get the most out of your free evaluation, here is the quick guide on adding screen video recording functionality into your application.

• run Visual Studio and create New Project.
• add reference to Screen Capturing SDK using Project | Add Reference. In the Add Reference dialog select “Bytescout Screen Capturing Lib” and click OK.
• copy-and-paste the following code:

Visual Basic:
