Hi,

You can use the following VB.NET code (via Spire.DataExport, a Free Data Export Component):

Private Sub btnText_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnText.Click
    Dim oleDbConnection1 As New System.Data.OleDb.OleDbConnection()
    oleDbConnection1.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=..\..\..\..\Database\demo.mdb"

    Dim oleDbCommand1 As New System.Data.OleDb.OleDbCommand()
    oleDbCommand1.CommandText = "select * from parts"
    oleDbCommand1.Connection = oleDbConnection1

    Dim txtExport1 As New Spire.DataExport.TXT.TXTExport()

    txtExport1.ActionAfterExport = Spire.DataExport.Common.ActionType.OpenView
    txtExport1.DataFormats.CultureName = "zh-CN"
    txtExport1.DataFormats.Currency = "c"
    txtExport1.DataFormats.DateTime = "yyyy-M-d H:mm"
    txtExport1.DataFormats.Float = "g"
    txtExport1.DataFormats.[Integer] = "g"
    txtExport1.DataFormats.Time = "H:mm"
    txtExport1.DataEncoding = Spire.DataExport.Common.EncodingType.ASCII
    txtExport1.SQLCommand = oleDbCommand1

    oleDbConnection1.Open()

    txtExport1.ExportType = Spire.DataExport.TXT.TextExportType.SYLK
    txtExport1.FileName = "sample.slk"
    txtExport1.SaveToFile()

    txtExport1.ExportType = Spire.DataExport.TXT.TextExportType.CSV
    txtExport1.FileName = "sample.csv"
    txtExport1.SaveToFile()

    txtExport1.ExportType = Spire.DataExport.TXT.TextExportType.DIF
    txtExport1.FileName = "sample.dif"
    txtExport1.SaveToFile()

    txtExport1.ExportType = Spire.DataExport.TXT.TextExportType.TXT
    txtExport1.FileName = "sample.txt"
    txtExport1.SaveToFile()
End Sub
