I’m spending far too much time re-typing purchase vouchers into Tally when everything is already organised in Excel. I need a small utility that reads those spreadsheets and posts each row as a purchase entry in my Tally company, with all taxes, supplier details and inventory lines carried over exactly as they appear in the sheet. You are free to choose the most efficient route—Tally XML import, ODBC, TDL, or a Python/.NET bridge—so long as the final result is a one-click (or near one-click) process that any non-technical staff member can run on a Windows machine. Deliverables • Executable tool or script with a simple UI or clear command-line instructions • Mapping configuration so I can point new spreadsheet layouts to the correct Tally fields without cod...

• Description The objective is to create a prototype that sends our XML string via AS4 to a destination URL. You can start with <test>dummy</test> for now, but we will test with real xml. You will need to sign with the internal private key certificate and encrypt with the external public key certificate. The other side will decrypt with their private key certificate and verify our signature with our public key certificate. We will give you the certificates. You will then listen to our URL. They will send an async message 10-15 minutes later. We will give you access to our VPS, so the DNS will be routed to the VPS. You will need to verify their signature with their public key and decrypt the message with our private key. Success metrics are that the message is successfull...

I have four Excel workbooks that I now need housed in an existing MS Access database. None of the sheets are relational at the moment, so the job is a straight import and structure clean-up rather than designing complex links. Here’s what I need from you: • Import 4 existing Excel Files into 4 tables in an existing MS Access DB (.ACCB) • Add a few basic queries so I can filter, sort and export the data quickly. • Delete bad data and duplicates The project is to be done in .net with WPF user interface. Once complete, send me the .accdb file and the brief how-to notes—that’s it. If something in the data suggests a better structure, feel free to flag it before you proceed; otherwise, a clean one-to-one migration is all I’m after.

We have a legacy Windows desktop application built on .NET Framework 4 that captures video from a USB webcam using and a custom wrapper WebCam_Capture.dll. The program works correctly on some machines but fails to recognize our Veho USB camera on others, even though the camera works in modern apps (Windows Camera app, browsers, online webcam testers). We need a freelancer to analyze, patch, and improve the camera handling logic so that the software consistently recognizes the camera across all machines. ⸻ Key Requirements / Skills: • Strong experience with .NET Framework 2.0–4.x and C# • Experience with DirectShow / video capture pipelines • Comfortable with Windows desktop apps (WinForms/WPF) • Experience with reverse engineering / decompiling .NET assem...

My WPF desktop app is halfway there; the core logic is working, but the presentation layer and final polish still need attention. I already have a detailed UI specification, so you can focus on bringing the remaining screens to life in XAML, wiring them cleanly into the MVVM structure, and making the whole thing run smoothly against a SQL Server back end. Here is what still needs doing: • Implement every control, style, animation, and layout exactly as shown in the spec. • Connect views to the existing SQL-driven data layer through well-structured ViewModels, keeping bindings clean and testable. • Profile memory, rendering, and startup behaviour, then eliminate the bottlenecks so large result sets scroll without stutter. I’ll hand over the current Visual Studio ...

I need a small Windows-only application that can take a folder of 20–100 TIFF files, apply a unique pixel shift and crop to each image, then save the processed set to disk. After that, the program should average the processed images into a single composite frame and finally assemble every frame into a short video clip. All parameters—image size, batch size, per-file pixel shift, crop dimensions, output frame rate and any other relevant image settings—must be editable from a clean, graphical interface that carries my company logo. No multilingual support is required, so the UI can stay in English. To speed things up I can supply an existing Lua script that demonstrates the core image calculations; feel free to translate or rewrite it in the language you are most comforta...

I need a Windows-based typing application, built to mirror the exact pattern used in Indian government recruitment exams. The program must run smoothly in both online and offline mode so that a candidate can practise anywhere and then sit a timed test even if the internet drops. Core functionality • Practice mode stocked with graded typing exercises. • Full-length mock tests that reproduce the official exam interface, timer and font rendering. • A performance dashboard that tracks speed, accuracy and trend lines over time. Language support All content, UI prompts and result reports should work in English and Hindi from day one. If you architect the system cleanly I can add further regional languages later, so keep strings externalised. Benchmarks Speed and accur...

I need a production-ready backend that powers a multi-tenant School Management SaaS. The stack is fixed—ASP.NET Core 8 Web API with EF Core and SQL Server—so you should be completely comfortable designing clean, modular code in that environment. Core scope • Build the entire API layer only; no front-end work. • Architect true multi-tenancy from day one, separating data per school while keeping shared services efficient. • Implement rock-solid authentication and authorization, plus fine-grained role-based access control. Day-to-day users include Students, Teachers, Parents, School Admins, Platform Admins and other school-specific roles, so permissions must be both flexible and secure. • Model every major domain: school setup/configuration, student/pa...

I have a desktop solution that mixes C# (WPF, a few ASP-NET-style service layers) and VB.NET (classic Windows Forms). Both stacks matter equally, so code will sometimes jump between the two. Current priorities are: • Robust user-authentication built directly into the client • Smooth, responsive data-visualisation screens (charts/grids) • Reliable file-handling routines for import, export and local storage The existing repository is in Git; each module compiles under the latest stable .NET. I’ll grant access branch-by-branch so we can review pull requests together before merging. Deliverable is a working desktop build with clear, well-commented source that shows the three features above fully integrated and tested on Windows 10/11. If a lightweight service o...

I need an experienced .NET and Blazor developer who can give my product a full-time focus—eight hours a day ,starting asap —while working side-by-side with my lead engineer during Indian Standard Time. The codebase is already in production; our goal over the coming weeks is to tidy up rough edges, harden performance, and keep new issues from sneaking in as we roll out incremental updates. Tech stack you’ll touch daily: ASP.NET Core APIs, a Blazor front end that leans on hooks and functional components, JSON-heavy data exchange, and Azure resources provisioned with Bicep. You’ll be handling pull requests, writing clean commits, and jumping on quick Teams or Slack calls whenever a change needs clarification. Expect a straightforward workflow—branch, code, PR, r...

I need a browser-based system that lets me run every aspect of our carpark from any Windows PC without installing extra software. The core of the build is flexible customer handling: I must be able to set up and manage short-term, long-term and annual accounts with independent pricing, expiry rules and access limits. For customers who park “on account”, the system has to trigger an automatic email on the 20th of each month containing their balance and payment link, so scheduling and SMTP integration are essential. A live dashboard should surface the three key metrics I use to steer the business—revenue, customer-usage statistics and occupancy rates—with the option to export each report to CSV or PDF. Drilling down into any figure should reveal the underlying tra...

I have a C# application that is now locked behind WinLicense + Themida 3.x. My only goal is to regain access to the project so I can open it in Visual Studio and continue working on it. I do not need a ready-to-run executable; what I’m after is clean, compilable source code. Once unpacked, I want to see: • the full user-interface layout and resources, • the core functionality and algorithms, and • all data-processing and storage routines. A straightforward Visual Studio solution (.sln, .csproj, assets, references) with clear build instructions will be considered a complete delivery. If any sections remain obfuscated, please document the reasons and suggest next steps.

I need assistance installing Visual Studio 2022 on Windows 11 and creating an MSI installer for it. I am a Visual Basic developer, but have hit a problem creating an installer and would like some assistance/guidance. I recently updated the application to use Nuget packages and Net 8.0 and am struggling getting the dlls to install correctly. The VS installation creator is picking up the wrong sql server and system dlls. The application includes two extensions, Component One and DevExpress I suspect the problem might be because the extensions are using different versions of the system and sql server dlls. Is this something you can help with please? Requirements: - Create an MSI installer for the setup of a desktop application Ideal Skills: - Experience with Visual Studio 2022 and Ne...

I run a project with a large-scale, custom integration to SAP S/4 HANA and now need an expert who knows the Sales and Distribution area inside out. The technical landscape already includes an extensive C# service layer that exchanges data with S/4, so the ideal partner is comfortable discussing both functional SD scenarios and how they translate into .NET code and APIs. Your main focus will be to examine my current SD setup, identify any gaps or mis-alignments with best practice, and guide me through the right configuration or enhancements. Whether the issue lies in pricing, order processing, delivery scheduling, or billing flows, I want pragmatic recommendations I can apply immediately and, when needed, hands-on help inside the system. Experience with the relevant SAP tools—SPRO,...

My donation-counter application (VB.NET, ASP.NET, SQL Server) currently treats the day as four 6-hour shifts. I need the underlying logic switched to three 8-hour shifts—nothing else about the feature set is changing and the screens can stay exactly as they are. Core work • Rework the scheduling code so every function that references shift boundaries now recognises 00:00-07:59, 08:00-15:59 and 16:00-23:59 (or equivalent server-time logic). • Update the existing SQL reports and any stored procedures that aggregate by shift so their totals align with the new 8-hour blocks. Acceptance I’ll verify by running a full day’s test data: the counters must roll over at the new cut-off times and all daily/shift reports must balance against those timestamps. This ...

I have an in-house VB.NET application backed by SQL Server 2008 R2 that currently schedules four 6-hour shifts per day. Operational changes now require three 8-hour shifts instead. The change touches two main areas: • Business logic – all routines that build the daily roster, assign staff and calculate shift boundaries work off the 4 × 6 model. • Database structure – several tables store fixed shift identifiers, start / end times, and downstream references that assume four records per day. Because the scheduling and allocation algorithms drive time-sensitive workflows, any adjustment must keep existing calculation accuracy intact. The user interface itself can stay as is; only back-end logic and schema need attention. What I need delivered 1. Updated ...

I’m moving our freight-invoice workflow off a Windows-only desktop utility and into a fully SQL Server–driven pipeline. All business rules live in clear documentation, every data source has been mapped, and I have a year’s worth of validated invoices to prove the expected outputs. Here is the flow I need implemented: CSV files arrive from carriers, they are ingested into staging tables, T-SQL stored procedures match each line to the appropriate rate-card logic, the correct freight charges are calculated, and the results are surfaced through an API. The API’s main purpose is to let our client application migrate data and trigger the stored-procedure processing as needed. To keep us aligned, these are the concrete deliverables: • Schema for raw, staging, and ...
