This tutorial is a continuation of our previous topic called Creating MySQL Connection using VB.Net, and this time, I will teach you How to Load MySQL Data Using VB.Net Application to DataGridVIew. Please follow all the steps to complete this tutorial successfully.

What is Visual Basic’s purpose?

The third-generation programming language was created to aid developers in the creation of Windows applications. It has a programming environment that allows programmers to write code in.exe or executable files.

They can also utilize it to create in-house front-end solutions for interacting with huge databases. Because the language allows for continuing changes, you can keep coding and revising your work as needed.

However, there are some limits to the Microsoft Visual Basic download. If you want to make applications that take a long time to process, this software isn’t for you.

That implies you won’t be able to use VB to create games or large apps because the system’s graphic interface requires a lot of memory and space. Furthermore, the language is limited to Microsoft and does not support other operating systems.

Retrieving data is very important in all Desktop Application especially in a program focusing on storing data. By retrieving it, you can display, modify, and remove specific data.

Load MySQL Data Using in VB.Net Application to DatagridView Steps:

Step 1

Right-Click your project and add a new “Windows Form” and name it “ViewRecords”.

Step 2

Insert a datagridview from your toolbox. The form should like the image below.

Step 3

View the code designer of your new created form and insert the following codes below. Double click your form to generate the form load event and insert the code below.

When the form is loading or running, all of the statements inserted inside the form load event will executed.

Try
Str = "SELECT * FROM tablename"
conn.Open()
Dim Search As New MySqlDataAdapter(Str, conn)
Dim ds As DataSet = New DataSet
Search.Fill(ds, "tablename")
data_view.DataSource = ds.Tables("tablename")
conn.Close()
Catch ex As Exception
MsgBox(ex.Message)
conn.Close()
End Try

tablename – The name of the table that you want to load from MySQL Database

data_view – The name of your new inserted DatagridView. It is recommended that you rename your DatagridView.

Step 4

Load your program and the form should look like the image below.

This feature is needed when working on the update and delete function in your application.

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:

1. Extract the archive to a folder outside Program Files (avoids permission issues).
2. Open the .sln file in Visual Studio. It loads the full solution with all forms and modules.
3. Restore NuGet packages. Right-click the solution then Restore NuGet Packages if prompted.
4. Import the database. Locate the .sql file in the archive and import via phpMyAdmin (MySQL) or SQL Server Management Studio.
5. 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.

Modules typical of How to Load Data from MySQL to DatagridView

• Master data. CRUD forms for the primary entities the system manages, with search and filter.
• Transaction processing. Data entry forms for the day-to-day operations the system automates.
• Reports. Formatted printable output summarizing activity per day, per user, or per category.
