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

PropertyDescription
1. AcceptsReturnGets or sets a value indicating whether pressing ENTER in a multiline TextBox control creates a new line of text in the control or activates the default button for the form.
2. AutoCompleteCustomSourceGets or sets a custom System.Collections.Specialized.StringCollection to use when the AutoCompleteSourceproperty is set to CustomSource.
3. AutoCompleteModeGets or sets an option that controls how automatic completion works for the TextBox.
4. AutoCompleteSourceGets or sets a value specifying the source of complete strings used for automatic completion.
5. CharacterCasingGets or sets whether the TextBox control modifies the case of characters as they are typed.
6. FontGets or sets the font of the text displayed by the control.
7. FontHeightGets or sets the height of the font of the control.
8. ForeColorGets or sets the foreground color of the control.
9. LinesGets or sets the lines of text in a text box control.
10. MultilineGets or sets a value indicating whether this is a multiline TextBox control.
11. PasswordCharGets or sets the character used to mask characters of a password in a single-line TextBox control.
12. ReadOnlyGets or sets a value indicating whether text in the text box is read-only.
13. ScrollBarsGets or sets which scroll bars should appear in a multiline TextBox control. This property has values −

  • None
  • Horizontal
  • Vertical
  • Both
14. TabIndexGets or sets the tab order of the control within its container.
15. TextGets or sets the current text in the TextBox.
16. TextAlignGets or sets how text is aligned in a TextBox control. This property has values −

  • Left
  • Right
  • Center
17. TextLengthGets the length of text in the 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

Frequently Asked Questions

How does this VB.NET project work?

Built with VB.NET WinForms (.NET Framework 4.5+) and SQL Server backend. Standard structure: Form designer to code-behind event handlers to ADO.NET data access layer to SQL Server. Login form for auth. Ready to extend for BSIT capstone scope.

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.

Where can I find more VB.NET projects with source code?

Browse the VB.NET Projects hub for the full library. For C# WinForms alternatives see C# Projects. For ASP.NET web alternatives see ASP.NET Projects. For BSIT capstone idea lists see 150 Best Capstone Project Ideas.
