• is .NET 4.0, double-click folder NET4.0

select these two assemblies: Spire.DataExport.dll and Spire.DataExport.ResourceMgr.dll, and click OK to add it to the project.

4. In Solution Explorer, double-click the file Form1.cs/Form1.vb to open the form design view, add a button into the form, and change its name to 'btnRun', change its text to 'Run'.

8. Add the following codes to the top of the file

using System.Data;
using System.Data.OleDb;

Imports System.Data
Imports System.Data.OleDb

9. Add the following codes to the method btnRun_Click

using (IDbConnection conn = new OleDbConnection())
{
//the data source demo.mdb was installed during installing Spire.DataExport,
//so the path of the data source may be different yours.
conn.ConnectionString
= @"Provider=Microsoft.Jet.OLEDB.4.0;"
+ @"Data Source=C:\Program Files\e-iceblue\Spire.DataExport\Demos\Database\demo.mdb";
conn.Open();

IDbCommand command = new OleDbCommand();
command.Connection = conn;
command.CommandText = "select * from parts";

this.cellExport.SQLCommand = command;
this.cellExport.SaveToFile();
}

Using conn = new OleDbConnection()
'the data source demo.mdb was installed during installing Spire.DataExport,
'so the path of the data source may be different yours.
conn.ConnectionString _
= "Provider=Microsoft.Jet.OLEDB.4.0;" _
& "Data Source=C:\\Program Files\\e-iceblue\\Spire.DataExport\\Demos\\Database\\demo.mdb"
conn.Open()

Dim command As New OleDbCommand()
command.Connection = conn
command.CommandText = "select * from parts"

Me.cellExport.SQLCommand = command
Me.cellExport.SaveToFile()
End Using

10. In Solution Explorer, right-click the project SimpleCellExport and click Debug, then Start new instance, you will see the opened window Form1, click the button 'Run', an Excel workbook will be generated, and opened. It looks the same as the following picture:
