Read windows registry key

This library interacts with native Windows APIs. We leveraged the following node modules to enable Node.

Using the ffi node module, we can load Advapi In our Node. Similarly, we created a Node wrapper shell As you can see, in order to replicate the exact Windows API call in JavaScript, we needed to create the same function with the exact inputs and outputs of the same data type as the Windows native data types.

It also has a return value of type BOOL , which represents the result of executing this call. Luckily, we had ref , ref struct , and ref union node modules to help us create the same struct in Javascript.

For each struct member, we looked up its data type and its size from the Windows Data Types reference , then created the same data type with the same properties in types. We leveraged the ref node module to create types.

This instance can then be used as a parameter of ShellExecuteExA so that we can launch a process with elevated privilege. We implemented this as an asynchronous call so that when the UAC User Account Control prompt is launched, the current process can continue to run without waiting on the user to respond.

The process you want to launch with admin access will only be launched after the callback is called and only if the user clicks Yes in the UAC prompt. Otherwise, the process will not be launched. If the user is already running as an admin, the UAC prompt will not be triggered and the process you provided will be launched as an administrator automatically. To install node modules that require compilation on Windows, make sure you have installed the necessary build tools.

Specifically, you need npm install -g node-gyp , a cross-platform cli written in Node. What Is svchost. Best Home Theater Systems. Best Smartwatches. Best Gaming Laptops. Best Smart Displays. Best Home Security Systems. Best External Solid State Drives. Best Portable Chargers. Best Phone Chargers.

Before reading the string you need to give the proper length of the string either you will get an error. I will store and read the stored value from the key using the above-described methods. Skip to content.
