主题：请问能否应用到xls模板打印中

参考代码

Dim Book As New XLS.Book(ProjectPath & "Attachments\订单模板.xls")
Dim fl As String = ProjectPath & "Reports\订单.xls"
Book.Build() '生成细节区
Book.Save(fl) '保存工作簿

Dim App As New MSExcel.Application
Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open(fl)
Dim i,N As Integer
N=Wb.WorkSheets.Count
For i=1 To N
    Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(i)
    ws.UsedRange.Formula = ws.UsedRange.Formula
Next
app.visible = True
