我的代码如下：提示wdBorderBottom未定义，老师我的vba只能照猫画虎的改一下，着急用这个功能，烦劳老师，给看看，修改一下

Dim app As New MSWord.Application
try
    Dim fileName = "e:\a.doc"
    Dim doc = app.Documents.Open(fileName)
    For Each oSec As object In doc.Sections
        Dim myRange = oSec.Footers(MSWord.WdHeaderFooterIndex.wdHeaderFooterPrimary).Range
        myRange.Delete
        Dim myRange2 = oSec.Headers(MSWord.WdHeaderFooterIndex.wdHeaderFooterPrimary).Range
       
        myRange2.Delete
        myRange2.ParagraphFormat.Borders(wdBorderBottom).LineStyle = wdLineStyleNone
    Next  
   
    doc.saved = True
    doc.ExportAsFixedFormat("e:\w.pdf",  MSWord.WdExportFormat.wdExportFormatPDF)
catch ex As exception
    msgbox(ex.message)
finally
    app.Quit
End try
