How to set up the Point of Sales and Inventory System in VB.Net?

Time needed: 3 days

Here’s the step-by-step guide on how to set up the Point of Sales and Inventory System

Technology stack and requirements

To run this VB.NET project, you need the following on your development machine:

Visual Studio 2019 or later. The free Community Edition is enough for building, debugging, and running the project.
.NET Framework 4.7.2 or higher. Most Windows 10 and 11 systems have it preinstalled through Windows Update.
MySQL Server 8.0 or MSSQL Express 2019. Choose whichever your capstone panel prefers; both work with VB.NET data adapters.
MySQL Connector/NET or SqlClient library. Add via NuGet Package Manager inside Visual Studio.
Crystal Reports (optional). Required only if the project generates printable reports; install the runtime redistributable.

Installing the source code

The download link contains a ZIP archive with the full solution. Extract and set up in five steps:

Extract the archive to a folder outside Program Files (avoids permission issues).
Open the .sln file in Visual Studio. It loads the full solution with all forms and modules.
Restore NuGet packages. Right-click the solution then Restore NuGet Packages if prompted.
Import the database. Locate the .sql file in the archive and import via phpMyAdmin (MySQL) or SQL Server Management Studio.
Update the connection string in App.config or module code to match your local database name, user, and password.

How to use this project for your BSIT capstone

This VB.NET project maps cleanly to standard BSIT capstone documentation. Suggested chapter alignment:

Chapter 1 (Introduction). Discuss the problem the system solves in real-world context. Cite Philippine business or academic use cases where a manual process could be replaced.
Chapter 2 (Review of Related Literature). Compare this system’s features against 5-10 similar published projects. Cite journals like IJERT or IEEE Access for academic-standard sources.
Chapter 3 (Methodology). Include Use Case Diagram, Data Flow Diagram, Entity Relationship Diagram, and Activity Diagram covering all major workflows in the system.
Chapter 4 (Results and Discussion). Screenshot each module of the running system with a caption explaining what data it processes and which user role interacts with it.
Chapter 5 (Conclusion and Recommendations). Identify features that could be added in a Version 2, such as web dashboard, mobile app, or REST API export.

What Visual Studio and SQL Server versions does this VB.NET project require?

Most projects use VB.NET WinForms on .NET Framework 4.5+ with SQL Server 2012 Express or higher. To run: install Visual Studio 2019 / 2022 (Community is free) with the ‘Desktop development with .NET’ workload, install SQL Server Express + SSMS, open the .sln file, build, run.

How do I set up the database for this VB.NET project?

Open SQL Server Management Studio (SSMS) and connect to your SQL Server (e.g. localhost\SQLEXPRESS). Right-click Databases, choose Restore Database OR New Database then import the included .sql script. Update the connection string in App.config (or in code-behind Module) with your server name + credentials. Rebuild and run.

Can I use this VB.NET project for a BSIT capstone or thesis?

Yes, VB.NET is one of the most accepted languages by Philippine BSIT panels. Extend it: add role-based access (admin/staff/customer login redirect), Crystal Reports or RDLC reports, dashboards with Chart control, audit log, multi-branch support. Pair with Chapter 1-5 documentation matching your panel’s rubric.

Why am I getting ‘connection error’ or ‘cannot find SQL Server’?

Three common VB.NET issues: (1) Connection error: SQL Server isn’t running. Open SQL Server Configuration Manager and verify SQL Server (SQLEXPRESS) service is started. (2) Wrong server name in connection string. Try .\SQLEXPRESS, (local)\SQLEXPRESS, or your machine name. (3) Login failed: SQL Server is set to ‘Windows-only’ authentication. Switch to Mixed Mode in SSMS Server Properties, Security.
