vb.net - 如何在不提示用户的情况下覆盖 Excel 应用程序

Question

任何人都可以帮助我如何在不提示 VB.Net 中的用户的情况下覆盖 Excel 文件..

我已经尝试过这段代码，但它不起作用..

Dim xlsApp As New Excel.Application
Dim xlsBook As Excel.Workbook
Dim xlsSheet As Excel.Worksheet
Dim dir As String = Application.StartupPath & "\Template\SampleTemplate.xls"
xlsBook = GetObject(dir)
xlsSheet = xlsBook.Sheets("Per BPA Error Report")


xlsSheet.Range("C2:T2").Merge()

xlsApp.DisplayAlerts = False
xlsSheet.SaveAs(Application.StartupPath & "\Template\SampleTemplate.xls")
xlsBook = Nothing
xlsSheet = Nothing
xlsApp.Quit()

Public Sub WriteExcelFile(ByVal ExcelFilePath As String) 
    Dim excel As Application = New Application
    Dim w As Workbook = excel.Workbooks.Open(ExcelFilePath)
    Dim sheet As Worksheet = w.Sheets(1)
    sheet.Cells(x + 1, 1) = 10
    x = x + 1
    excel.DisplayAlerts = False
    w.Save()
    w.Close()
End Sub
