I used below code to open and fill an Excel file automaically. After that, save it.
However, after I call Workbook.SaveAs(Or Save), when I close the Excel file. I always be asked "The content of this file is changed, do you want to save it?
But the content has already been saved indeed
Then why that message is showed? How to clear it?

Dim ExcelForm As New Excel.Applicatio
Dim exwbook As Excel.Workboo
Dim exsheet As Excel.Workshee
Dim file As New FileInfo("C:\template.xls"

If file.Exists = True The
file.Delete(
End I

Dim fs As FileStream = file.Create(
fs.Close(

ExcelForm = CreateObject("Excel.Application"
ExcelForm.Visible = Tru

exwbook = ExcelForm.Workbooks.Open("C:\template.xls"
exsheet = exwbook.Worksheets("template"

exsheet.Cells(1, 1) = ... ..

exwbook .SaveAs("C:\template.xls) 'Or exsheet.Save(
