Below is a function w/ a working example showing how to access the AIDA64 shared memory.
First enable shared memory here: Preferences > Hardware Monitoring > External Applications > Enable Shared Memory
The length of the data depends on the number of active sensors and their content. As AIDA64 does not provide a buffer size value, we use _WinAPI_GetSystemInfo() <WinAPISys.au3> to get dwPageSize ($aArray[1]). This value is the used as an address offset, and we continue reading chunks of data until we encounter a 0x00 NUL character.
Based on the Delphi example found in the AIDA64 documentation: https://www.aida64.co.uk/user-manual/external-applications
Feedback appreciated, especially as all this shared memory stuff is not my ordinary cup of... cake. And regarding this whole ordeal of reading data without knowing the exact length; I'm suspecting my solution to read chunks of data like done below is not by the book, and I'm concerned what might happen if the final chunk is exactly 4096 bytes in length. Will there still be a NUL terminator there? Hmm.

About Autoit-Socket-IO
Autoit-Socket-IO is a event driven TCP/IP wrapper heavily inspired from Socket.IO with focus on user friendliness and long term sustainability.
I constantly want to make this UDF faster and better, so if you have any suggestions or questions (beginner and advanced) Do not hesitate to ask them, I will gladly help!
Key features
Simple API 99% data-type serialization thanks to Autoit-Serialize Can easily be extended with your own functionality thanks to Autoit-Events "Educational" examples Data encryption thanks to _<Crypt.au3> Limitations
Speed. This UDF will sacrifice some speed for convenience Getting started
Download the script from AutoIt or pull it from the official github repo git@github.com:tarreislam/Autoit-Socket-IO.git and checkout the tag 4.0.0-beta Check out the documentaion Take a look in the examples/ folder Changelog
To see changes from 3.x.x and 2.x.x please checkout the 3.x branch
Version 4.0.0-beta (This update break scripts.)
Code base fully rewritten with Autoit-Events and decoupled to improve code quality and reduce bloat. The new UDF is very different from 3.x.x so please checkout the UPGRADE guide to fully understand all changes Added new documentation documentaion Success stories
Since December 2017-now I have used version 1.5.0 in an production environment for 150+ clients with great success, the only downtime is planned windows updates and power outages.

Hi there - creating a simple script to triger cctv software to turn on when my phone is not connected to home wifi. But having issues with my phone (samsung s7) not answering ping when sleeping (despite wifi set to work when sleep) - not sure the issue... and ideas? 
Alternatively was wondering about pinging the bluetooth address of the phone - anyway to get this working in autoit?

Purpose (from Microsoft's website)
The HTTP Server API enables applications to communicate over HTTP without using Microsoft Internet Information Server (IIS). Applications can register to receive HTTP requests for particular URLs, receive HTTP requests, and send HTTP responses. The HTTP Server API includes SSL support so that applications can exchange data over secure HTTP connections without IIS.
Description
There have been several times in the past that I wanted to either retrieve information from one of my PCs or execute commands on one of my PCs, whether it was from across the world or sitting on my couch.  Since AutoIt is one of my favorite tools for automating just about anything on my PC, I looked for ways to make to make it happen.  Setting up a full blown IIS server seemed like overkill so I looked for lighter weight solutions.  I though about creating my own AutoIt UDP or TCP server but that just wasn't robust enough,  Then I found Microsoft's HTTP Server API and it looked very promising.  After doing a little research into the APIs, I found that it was flexible & robust enough to handle just about any of the tasks that I required now and in the future.  So a while back I decided to wrap the API functionality that I needed into an AutoIt UDF file to allow me to easily create the functionality I needed at the time.  It has come in very handy over the years.  Of course it wasn't all wrapped up with a nice little bow like it is now.  That only happened when I decided to share it with anyone else who could use it or learn from it.
The example file that I included is a very granular example of the steps required to get a lightweight HTTP Server up and listening for GET requests.  The UDF is a wrapper for the Microsoft APIs.  That means to do anything over and above what I show in the example, one would probably have to have at least a general knowledge of APIs or the ability to figure out which APIs/functions to use, what structures and data is needed to be passed to them, and in what order.  However, the UDF gives a very solid foundation on which to build upon.  Of course, if anyone has questions about the UDF or how to implement any particular functionality, I would probably help to the extent that I could or point you in the right direction so that you can figure out how to implement your own solution.
The APIs included in the UDF are the ones that I needed in the past to do what I needed to do.  If any additional APIs need to be added to the UDF file, please make those suggestions in the related forum topic.
Being that this is basically an AutoIt wrapper for the Microsoft API functions, there's no need to create AutoIt-specific documentation.  All of the UDF functions, structures, constants, and enumerations are named after their Microsoft API counterparts.  Therefore, you can refer to Microsoft's extensive documentation of their HTTP Server API.  As stated earlier, if there is one or more APIs that you find yourself needing for your particular solution, please suggest it in the related Example Scripts forum topic.
