I need a small Visual Basic desktop utility that will open an Excel worksheet containing five numeric columns and as many as 50,000 rows. For every row the program must produce every requested subset combination of those five numbers—for example pairs, triplets or any other subset size I select through the interface—and return the final count of generated combinations. Key functional points • Only numbers ≤ 100 are permitted in the calculation; anything greater is ignored automatically. • The data set can be large, so the code has to process it without freezing the UI and should show a simple progress indicator. • A clean, single-screen form is enough: file picker, subset-size selector (pairs, triplets, etc.), a “Run” button, a live counter and an option to export the resulting combinations or at least the total count to a new sheet or CSV. Please build it in standard Visual Basic (VB.NET is preferred so I can recompile later) and include the full, well-commented source along with the compiled executable.

Hey! We can build a lightweight, efficient VB.NET desktop utility that processes large Excel datasets reliably without locking up the UI. We’re a team of 62 professionals with over 9 years of experience delivering performance-focused desktop tools, data-processing utilities, and Excel-integrated applications. Here’s how we can help: * Develop a VB.NET Windows desktop app with a clean, single-screen interface * Load Excel worksheets with up to 50,000 rows and five numeric columns efficiently * Filter values automatically to include only numbers ≤ 100 in all calculations * Generate subset combinations (pairs, triplets, or any selected size) per row and return accurate counts * Run processing asynchronously to keep the UI responsive, with a simple progress indicator and live counter * Enable export of total counts or generated combinations to a new Excel sheet or CSV * Deliver fully commented source code plus a compiled executable for future recompilation To scope this precisely, do you need the combinations generated independently per row or aggregated across the full dataset? Also, should the export include all combinations (which could be very large) or primarily the final counts per row or per run?

Hi, thanks for your job posting. I can develop a small VB.NET desktop utility that reads your Excel worksheet and generates all requested numeric subset combinations for each row, supporting pairs, triplets, or any subset size you select. The program will automatically ignore numbers greater than 100 and efficiently handle large datasets of up to 50,000 rows without freezing the UI, including a simple progress indicator. A clean, single-screen interface will provide a file picker, subset-size selector, “Run” button, live counter, and options to export results or total counts to a new sheet or CSV. The code will be well-structured, fully commented, and easy to recompile or extend in the future. I will deliver both the compiled executable and the complete source code. My goal is to provide a reliable, fast, and user-friendly tool that meets your combination-counting needs. Best regards. Jijo

Hello, I’m excited about the opportunity to build this VB.NET desktop utility to process large Excel sheets and generate the requested subset combinations reliably and fast. I can implement a single-screen WinForms app with a file picker, subset-size selector, Run button, live counter and progress indicator, filtering out any values greater than 100 automatically before generating combinations. To keep the UI responsive on 50,000-row files, I’ll run the processing asynchronously with proper cancellation-safe progress updates, and I’ll optimize the combination generation so it avoids unnecessary allocations while still supporting exporting either the full combination list (when feasible) or the total count to a new sheet or CSV. You can expect clean, well-commented source code you can recompile later, plus a compiled executable and a brief handoff note explaining the build and usage. Best regards, Juan
