blackout sensitive info on screen video in VB.NET using ByteScout Screen Capturing SDK

How to code blackout sensitive info on screen video in VB.NET: How-To tutorial

ByteScout tutorials explain the material for programmers who use VB.NET. ByteScout Screen Capturing SDK was made to help with blackout sensitive info on screen video in VB.NET. ByteScout Screen Capturing SDK is the SDK for developers for quick implementation of screen video recording. The SDK records screen into video or into a series of screenshots. Can also record audio. Saves video into AVI,WMV and Google’s WebM. Output video quality, size, resolution or framerate can be adjusted easily. Provides additional tools for privacy features like blacking out on scren areas with sensitive information on screen right during recording. Supports web camera as input and can add instant text and images into video output.

Fast application programming interfaces of ByteScout Screen Capturing SDK for VB.NET plus the instruction and the VB.NET code below will help you quickly learn blackout sensitive info on screen video. Follow the instruction from the scratch to work and copy and paste code for VB.NET into your editor. This basic programming language sample code for VB.NET will do the whole work for you in implementing blackout sensitive info on screen video in your app.

' NOTE: if you are getting error like "invalid image" related to loading the SDK's dll then 
' try to do the following:
' 1) remove the reference to the SDK by View - Solution Explorer
' then click on References, select Bytescout... reference name and right-click it and select Remove
' 2) To re-add click on the menu: Project - Add Reference
' 3) In "Add Reference" dialog switch to "COM" tab and find Bytescout...
' 4) Select it and click "Add" 
' 5) Recompile the application 
' Note: if you need to run on both x64 and x86 then please make sure you have set "Embed Interop Types" to True for this reference
