C++ ScreenGrabber and HTTP poster

Hello, I need a POC of a software that does the following - A software that monitors the windows screen for changes every X milliseconds Once a change was detected, it grabs the region that was changed as a jpg It then sends the jpg+the coordinates of the region to the server, which is a web server. This can be done via simple http post of the jpg+ Our web server we also use "pokein" - [login to view URL] So if this helps in any way, feel free to download the free version of pokein The most important thing here, is that by the end of this project we will get - 1 - full Visual Studio C++ project that can compile without any special configuration (we are not expert in c++) 2- The ONLY thing the use will need is the [login to view URL] . No other DLL will be required, no setup! 3 - We should be able to modify the URL where it submits the images quickly. Also - we should be able to add to the URL a query string (e.g. - [login to view URL]) 4- Once the software loads, it should access the server and call some URL (which we should be able to change later) and get a JSON format that has the client ID (for now, and for testing - you can just use a static file. In real life, the url will generate a unique ID based on the user) 5 - The above ID should be used when posing the jpg and coordinates later - see bullet no. 3 This is it:) Happy bidding!
