问题描述

我收到一个错误,当我在VS 2010中运行这个程序(正常工作在VS 2008中)

I am getting an error when I run this app in VS 2010 (it works fine in VS 2008)

私人小组GenerateInvoice()

Private Sub GenerateInvoice()

Dim emptyObject As Object = System.Reflection.Missing.Value

Dim wordApp As New Word.Application
wordApp.Visible = True

Dim InvoiceDoc As New Word.Document
InvoiceDoc = wordApp.Documents.Add(InvoicePath, emptyObject, emptyObject, emptyObject)

Dim totalFields As Integer = 0

For Each mergeField As Word.Field In InvoiceDoc.Fields

出现的错误在每行

The error occurs at the For Each line

对象未设置为一个  实例对象的。

我失去了一些东西呢?

推荐答案

也许 InvoicePath 在通过VS2010运行实例中使用是无效的,因此调用 Documents.Add 失败?

Maybe the InvoicePath used in the instance run via VS2010 is invalid and so the call to Documents.Add fails?

您在同一台机器上同时运行VS2010和VS2008?而在 InvoicePath 设置完全相同的路径在这两种情况?

Are you running both VS2010 and VS2008 on the same machine? And is the InvoicePath set to the exact same path in both instances?
