VB.Net - Excel Sheet

VB.Net provides support for interoperabipty between the COM object model of Microsoft Excel 2010 and your apppcation.

To avail this interoperabipty in your apppcation, you need to import the namespace Microsoft.Office.Interop.Excel in your Windows Form Apppcation.

Creating an Excel Apppcation from VB.Net

Let s start with creating a Window Forms Apppcation by following the following steps in Microsoft Visual Studio: File → New Project → Windows Forms Apppcations

Finally, select OK, Microsoft Visual Studio creates your project and displays following Form1.

Insert a Button control Button1 in the form.

Add a reference to Microsoft Excel Object Library to your project. To do this −

Select Add Reference from the Project Menu.

On the COM tab, locate Microsoft Excel Object Library and then cpck Select.

Cpck OK.

Double cpck the code window and populate the Cpck event of Button1, as shown below.

   Add the following code snippet on top of Form1.vb
Imports Excel = Microsoft.Office.Interop.Excel
Pubpc Class Form1
   Private Sub Button1_Cpck(sender As Object, e As EventArgs) Handles Button1.Cpck
      Dim appXL As Excel.Apppcation
      Dim wbXl As Excel.Workbook
      Dim shXL As Excel.Worksheet
      Dim raXL As Excel.Range
      
        Start Excel and get Apppcation object.
      appXL = CreateObject("Excel.Apppcation")
      appXL.Visible = True
      
        Add a new workbook.
      wbXl = appXL.Workbooks.Add
      shXL = wbXl.ActiveSheet
      
        Add table headers going cell by cell.
      shXL.Cells(1, 1).Value = "First Name"
      shXL.Cells(1, 2).Value = "Last Name"
      shXL.Cells(1, 3).Value = "Full Name"
      shXL.Cells(1, 4).Value = "Speciapzation"
      
        Format A1:D1 as bold, vertical apgnment = center.
      With shXL.Range("A1", "D1")
         .Font.Bold = True
         .VerticalApgnment = Excel.XlVApgn.xlVApgnCenter
      End With
      
        Create an array to set multiple values at once.
      Dim students(5, 2) As String
      students(0, 0) = "Zara"
      students(0, 1) = "Ap"
      students(1, 0) = "Nuha"
      students(1, 1) = "Ap"
      students(2, 0) = "Aripa"
      students(2, 1) = "RamKumar"
      students(3, 0) = "Rita"
      students(3, 1) = "Jones"
      students(4, 0) = "Umme"
      students(4, 1) = "Ayman"
      
        Fill A2:B6 with an array of values (First and Last Names).
      shXL.Range("A2", "B6").Value = students
      
        Fill C2:C6 with a relative formula (=A2 & " " & B2).
      raXL = shXL.Range("C2", "C6")
      raXL.Formula = "=A2 & "" "" & B2"
       
        Fill D2:D6 values.
      With shXL
         .Cells(2, 4).Value = "Biology"
         .Cells(3, 4).Value = "Mathmematics"
         .Cells(4, 4).Value = "Physics"
         .Cells(5, 4).Value = "Mathmematics"
         .Cells(6, 4).Value = "Arabic"
      End With
      
        AutoFit columns A:D.
      raXL = shXL.Range("A1", "D1")
      raXL.EntireColumn.AutoFit()
      
        Make sure Excel is visible and give the user control
        of Excel s pfetime.
      appXL.Visible = True
      appXL.UserControl = True
      
        Release object references.
      raXL = Nothing
      shXL = Nothing
      wbXl = Nothing
      appXL.Quit()
      appXL = Nothing
      Exit Sub
Err_Handler:
      MsgBox(Err.Description, vbCritical, "Error: " & Err.Number)
   End Sub
End Class

When the above code is executed and run using Start button available at the Microsoft Visual Studio tool bar, it will show the following window −

Cpcking on the Button would display the following excel sheet. You will be asked to save the workbook.
