Here is the English translation of your full requirement: > I need an API-based software for Windows computers. The software will be used during vehicle PUC (Pollution Under Control) testing. > > The software should work without any direct connection to the PUC testing machine. The user will open this API software, select one of the required options, and then go to the PUC website. When the user clicks the machine value button on the website, the software should automatically send the corresponding values from the API to the website. > > The software interface will contain four different options. Each option will have its own predefined value range, and I will provide the maximum values for each option. Based on the selected option, the software should automatically transfer the appropriate values to the website. > > Every time the software is opened, it should remember the previously selected option (or use the selected configuration), and whenever the machine value button is clicked on the website, it should transfer values according to that option. The values should be different on every click, while remaining within the limits that I specify for each of the four options. > > The software should be transferable, but I want to control its usage through a license system. I should be able to assign an expiry date to each copy. After the expiry date, the software must stop working automatically and remain locked until I extend or renew the license. > > Additionally, if the software is copied from one computer to another, it should not run on the new computer. It should either remain locked or require authentication (such as a password or license verification), so that it can only be used on the computer for which it was originally [login to view URL] I am looking only for freelancers who have previously completed this type of project.

Automating the machine value button transfer without a physical connection requires a targeted script that mimics hardware input patterns. We previously managed a Software QA Testing Report where we ran end-to-end automation across 44 projects to ensure complex logic triggers exactly like manual actions, which you can see at https://www.freelancer.com/portfolio-items/11354470-software-qa-testing-report. I will build the Windows tool to hook into your specific PUC website and inject randomized values within your four predefined ranges. Each click will push unique data so the portal sees natural variability rather than a static duplicate. To handle security, I can implement a hardware ID lock. This ensures the software only runs on the specific authorized machine and automatically expires on the date you set in the license manager. One quick thing: Which specific browser and PUC website URL will the software target to ensure the DOM injection or API interception is compatible? Knowing this helps me give you a real number, not a guess. Happy to jump on a quick call when you're ready. ~ Rajesh

You need a Windows API tool that sends varied values from four preset ranges to a PUC website on each click, with a license system to control usage and expiry. That is a clear and specific ask, and I have built similar desktop software with license binding before, so I understand exactly what is required here. I would build this as a lightweight Windows application that stores the selected option and range limits locally, generates random values within those limits on each click, and sends them to the website via API calls. The license system would tie the software to a specific machine using hardware identifiers, with an expiry date stored either locally or checked against a simple server. would you like to discuss more on this ?

You want a Windows app that auto-fills machine values onto a PUC site, with strict licensing tied to hardware. Done this before for test automation—emulating device input without connecting the real machine. That means two parts: a small desktop app for user interaction and clipboard/keyboard injection, and a backend API for license and config control. Stack: Electron or native Windows (C#/Node.js) for the app, backend in Node.js/Express for license/auth, SQLite for value ranges and last option config. Licensing tied to hardware ID (like disk serial), not username, so copies won’t run elsewhere without reactivation. On expiry, app locks with a renewal prompt. One question: is the PUC site form a standard HTML page, or does it use any unusual input controls (ActiveX, Java applet)? That affects how the app simulates input. I can start on this—reply if you want a first cut walkthrough. Pradeep

The trickiest part here isn't injecting values into the website, it's doing it reliably without hooking into the PUC machine's driver or COM port. I'll build this as a lightweight Windows app that intercepts the browser's button click via a local HTTP server and injects randomized values (within your predefined ranges) through a browser extension or automation layer. The app will persist the last selected option locally, generate varied values on each click, and phone home to a simple license server I'll set up for you. For hardware locking, I'll bind each license to a hash of the machine's MAC address and disk serial, so copying the software to another PC won't work without reactivation. 1) Which browser does the PUC website run in, and does it use any ActiveX or Java plugin for the machine value button? Happy to talk details in chat. Shayan

Hi — Ankit here. I see you need a Windows API-based software for vehicle PUC testing that auto-transfers values to the PUC website without connecting to the testing machine, with four selectable value ranges, license expiry, and hardware-locking. What matters most here is reliable browser value injection and robust license protection. A common issue is the software working on one computer but failing when copied elsewhere. The tricky part is ensuring the license system binds to hardware (disk serial or MAC address) while allowing you to set expiry dates remotely . My approach focuses on building a lightweight Windows app (C# or Electron) that persists the last selected option locally, generates varying values within your specified ranges on each click, and injects them into the PUC website when the machine value button is clicked. The license system would bind each installation to a unique hardware ID, with remote expiry control through a simple admin panel . I've done similar test automation projects with hardware-locked licensing. A few questions: Q1 – Which browser does the PUC website run in, and does it use any ActiveX or Java plugin for the machine value button? Q2 – Do you have the maximum value ranges for each of the four options ready? Q3 – Do you prefer C# (.NET) or Electron for the Windows application? Happy to discuss details. Looking forward to hearing from you.

Hello, The key challenge is building a Windows application that reliably injects configurable values into the PUC website while remaining independent of the testing machine and protected by a secure licensing system. I would first analyze how the website triggers the machine value request, then implement configurable value generation, persistent settings, hardware-locked licensing with expiry, and comprehensive testing to ensure consistent behavior after updates. The solution should be modular so value ranges and licensing rules can be managed without changing the application. Does the PUC website expose an API, or is the interaction entirely browser-based? Should licenses be validated online or work completely offline after activation? If the approach matches your requirements, I'd be glad to discuss the implementation details. Thanks, Akshay
