How to Read an Excel file in Visual Basic.Net
In this tutorial, I will teach you how to read an excel file in Visual basic.net (VB.Net).
This tutorial can be integrated to your personalized vb.net project.
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.
So let’s get started:
Step How to Read an Excel file in Visual Basic.Net
- Step 1: First is open the Visual Basic, Select File on the menu, then click New and create a new project.
- Step 2: Then a New Project Dialog will appear. You can rename your project, depending on what you like to name it. After that click OK
- Step 3: Design your form like this just like what I’ve shown you below.
Add a 2 Textbox and a Button
- Step 4: After designing your form. Add a reference to Microsoft Excel 12.0 Object Library
In your project menu click on Project– Add Reference – go to COM tab
Add Microsoft Excel 12.0 Object Library
- Step 5: Then, go to the code page and add the following declarations:
Imports Excel = Microsoft.Office.Interop.Excel Public Class Form1 Dim APP As New Excel.Application Dim worksheet As Excel.Worksheet Dim workbook As Excel.Workbook
- Step 6: Add this following code to Form_Load Event
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load workbook = APP.Workbooks.Open("C:\Users\Clive\Documents\Visual Studio 2008\clive projects\writeandread\writeandread\bin\Debug\sales.xlsx") worksheet = workbook.Worksheets("sheet1") End Sub
Step 7: To get the value from Excel cell to TextBox. Add this following code to the Button Click Event.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _ Handles Button1.Click TextBox1.Text = worksheet.Cells(1, 1).Value TextBox2.Text = worksheet.Cells(1, 2).Value End Sub
Step 8: Then finally, add this code to save the Excel file and closes it.
Private Sub Form1_FormClosed(ByVal sender As System.Object, _ ByVal e As System.Windows.Forms.FormClosedEventArgs) _ Handles MyBase.FormClosed workbook.Save() workbook.Close() App.Quit() End Sub
- Step 9: Click F5 to run the program.
