By: Issac in VB.net Tutorials on 2009-01-31
We can see about OLEDB object which can be used to work with data in cell (i.e. insert, edit, delete, select etc), we can use OleDbConnection, OleDbDataAdapter and dataset for doing these operations in an Excel File, also you have to import system.Data
Sample Select sql
Sql = "select * from [Sheet1$]"
Here is the sample Excel file.
Open the connection using OLEDB Provider
(provider=Microsoft.Jet.OLEDB.4.0;Data Source='Your Filename';Extended Properties=Excel 8.0;)
Specify which data you want to read
select * from [Sheet1$]
Here is the screen shot after reading from Excel file.
Imports System.Data Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button1.Click Try Dim MyConnection As System.Data.OleDb.OleDbConnection Dim DtSet As System.Data.DataSet Dim MyCommand As System.Data.OleDb.OleDbDataAdapter MyConnection = New System.Data.OleDb.OleDbConnection _ ("provider=Microsoft.Jet.OLEDB.4.0;" _ " Data Source='c:\testfile.xls'; " _ "Extended Properties=Excel 8.0;") MyCommand = New System.Data.OleDb.OleDbDataAdapter _ ("select * from [Sheet1$]", MyConnection) MyCommand.TableMappings.Add("Table", "TestTable") DtSet = New System.Data.DataSet MyCommand.Fill(DtSet) DataGridView1.DataSource = DtSet.Tables(0) MyConnection.Close() Catch ex As Exception MsgBox(ex.ToString) End Try End Sub End Class
