If FileSys.FileExists(ProjectPath & "Attachments\" & str) Then

If Tables("订单主表.订单明细表").rows.count>0 Then

    If e.Form.Controls("CheckBox2").Checked Then

        Tables("订单主表.订单明细表").Select(0,0,Tables("订单主表.订单明细表").rows.count-1,0)

    End If

    Dim Book As New XLS.Book(ProjectPath & "Attachments\" & str) 

    Dim i As Integer

    Dim str1 As String = "订单交期,联系人,联系方式,传真,订单号"

    Dim str2 As String = "DateTimePicker1,TextBox3,TextBox1,TextBox2,TextBox4"

    For Each k As String In str2.split(",")

        Book.Marks.Add(str1.split(",")(i),e.form.Controls(k).Value)

        i += 1
