Setting up VB.NET to work with Excel

Click on File and click on New Project. Under Visual basic, Select “Windows” and then select “Windows Form Application”. Give the project an appropriate name and select a location where you want to save this project.

When the project opens you will be presented with Form1. For the time being just lets create 3 buttons and name then “Create”, “Open”, “Cancel”. Give an appropriate heading to the form. Your form should look like this.

Now let’s set references for Excel in our project. For this click on the menu Project~~>Add Reference. You will be presented with a “Add Reference”-dialog box. Navigate to the “COM” Tab and select the Microsoft Excel Object Library.

After setting the reference, double click on any of the button to open the Form1 Code Area and paste this line of code at the very top.

Imports Excel = Microsoft.Office.Interop.Excel

在.Net标签中可以找到
Microsoft.Office.Interop.Excel
Microsoft.Office.Tool.Excel
将这些都加入进来

Double-click on the third button “Cancel” and paste the code. This is how your code should look like.

Imports Excel = Microsoft.Office.Interop.Excel

 

Public Class Form1

    PrivateSub Button3_Click(ByValsender As System.Object, ByVal e AsSystem.EventArgs) HandlesButton3.Click

        Me.Close()

    EndSub

End Class

And you are all set for automating Excel From VB.Net.
