Clearing Text Controls using VB.Net with For Loop Statement

Clearing Text Controls using VB.Net with For Loop Statement

In this tutorial, you will learn how to Clearing Text Controls using VB.Net with For Loop Statement easily without making any long codes just to clear all the controls inside your form.

First you need to open your Microsoft Visual Studio IDE and create new project, name it as you please.

Then, drag the objects like textbox and combobox in your blank form as many as you like.

The Properties of the TextBox Control

The following are some of the commonly used properties of the TextBox control

Next, create a button. After creating a button or dragged from the toolbox, double click that textbox and insert this line of code.

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Dim clean as Control

For Each clean In Me.Controls
If TypeOf clean Is TextBox Then
clean.Text = Nothing
End If
Next

End Sub

Run your system and see for yourself that after clicking your button, the textboxes inside the form are being cleared.

You can also apply this line of code if you want to clear comboboxes, here’s the sample line of code with clearing all combobox in your form:

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Dim clean as Control

For Each clean In Me.Controls
If TypeOf clean Is TextBox Then
clean.Text = Nothing
ElseIf TypeOf clean Is ComboBox then
clean.text = Nothing
End If
Next

End Sub

You have created your own Clearing Text Controls using VB.Net with For Loop Statement.

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 Clearing Text Controls using VB.Net with For Loop Statement

• 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.
• User management. Login with role-based permissions (Admin, Encoder, Viewer).

Common enhancements for capstone review

• Modernize the UI. Add Bunifu or Guna UI controls for a more polished, modern appearance.
• Add printable receipts. Integrate a printer preview form with page-setup options.
• Multi-user concurrency. Ensure the database handles simultaneous writes without lost-update errors.
• Web version. Rewrite the front-end in ASP.NET Core or React for a modern deployment path.
