Each react element is a plain java-script object. In react, we simply change the state of our components and react will sync with Real DOM by itself. Each page can divided into components like: left pane, navbar, app. These components are created with the help of react js. React or Angular: Both of these have component based architecture. But angular is  framework, a complete solution and react is a library. React only take care of rendering the view and view is in sync with the state. For working with react you can easily use the other libraries like routing, calling https etc. With you get the libraries to be used also with react.

The IDE provided by Microsoft is Visual Studio.  It consists of three main parts:  the Common Language Runtime,  the Framework classes, and  ASP.NET. How is .NET able to support multiple languages?    In .NET, code is compiled to Microsoft Intermediate Language (MSIL). This is called as Managed Code. This Managed code is run in .NET environment. So after compilation to this IL the language is not a barrier. A code can call or use a function written in another language.  What are the major components of .Net?

Interaction with UI from windows service

I nteract ion with UI from windows service Introduction Windows service has no UI and it has never been easy to prompt users with some notifications from windows service. To interact with UI from windows service, we used to opt, allow service to interact with desktop and by launching another process from the windows service. But it is not expected to work with windows vista and upwards. So now the question is how to implement this in newer versions of windows i.e. windows 8, windows 10 etc. Here is the answer: Display a dialog box in the user's session using the  WTSSendMessage function. It can be used to display messages from windows service on all supported windows operating systems. WTSSendMessage Displays a message box on the client desktop of a specified Remote Desktop Services session. Syntax BOOL WTSSendMessageA(   IN HANDLE hServer,   IN DWORD   SessionId,   LPSTR      pTitle,   IN DWORD   TitleLength,   LPSTR      pMessage,   IN DWO

Code Sign In What is Code Signing? Code signing  is the method of using a certificate-based digital signature to sign executables and scripts in order to verify the author’s identity and ensure that the code has not been changed or corrupted since it was signed by the author. This helps users and other software to determine whether the software can be trusted. Purpose of Code Signing Because of the potential damage that an executable or script can cause to a computer system, it is important that users be able to trust code published on the Internet. Here are two important ways that Code Signing increases trust: ·        Authentication . Verifying who the author of the software is. ·        Integrity . Verifying that the software hasn’t been tampered with since it was signed. ·          What is a Code Signing Certificate? A code signing certificate allows you to sign code using a private and public key system similar to the method used by SSL and SSH. A public/pr
