Asp.net 在vb.net中打开和保存word文档-关闭可见性时出错

我正在打开一个word文档并用以下代码将其保存为html。如果我设置objWord.Visible=False，我会得到一个错误：HRESULT:0x800A1098中的异常，我认为这表明没有要打开的内容。 如果我设置objWord.Visible=True，代码将正常运行，但我不希望最终用户看到word的运行。非常感谢您的帮助

提前谢谢

Protected Sub btnUpload_Click(ByVal sender As Object, ByVal e As EventArgs)
    Dim objWord As Microsoft.Office.Interop.Word.ApplicationClass = New ApplicationClass()
    If Not (fUpload.HasFile) Then
        lblMessage.Text = "Please choose file to upload"
    Else
        Try
            Dim strFileName As String = fUpload.FileName
            Dim strSep As String() = fUpload.FileName.Split("."c)
            Dim arrLength As Integer = strSep.Length - 1
            Dim strExt As String = strSep(arrLength).ToString().ToUpper()
            'Save the uploaded file to the folder

            strPathToUpload = Server.MapPath("Uploaded")
            strPathToConvert = Server.MapPath("WordToHtml")
            Dim FileName As Object = (strPathToUpload & "\") + fUpload.FileName

            Dim FileToSave As Object = (strPathToConvert & "\") + Left(fUpload.FileName, Len(fUpload.FileName) - 4) & ".htm"
            If strExt.ToUpper().Equals("DOC") Then
                fUpload.SaveAs((strPathToUpload & "\") + fUpload.FileName)
                lblMessage.Text = "File uploaded successfully"

                'open file in word
                objWord.Documents.Open(FileName, missing, [readOnly], missing, missing, missing, missing, missing, missing, missing, missing, isVisible)

                objWord.Visible = False 'error occures here if False

                Dim oDoc As Microsoft.Office.Interop.Word.Document = objWord.ActiveDocument

                If oDoc.Application.Version = "12.0" Then ' Word 2007 version
                    oDoc.SaveAs2(FileToSave, fltDocFormat, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing)
                Else ' word 2003 version
                    oDoc.SaveAs(FileToSave, fltDocFormat, missing, missing, missing, missing, missing, missing, missing, missing, missing)
                End If

            Else
                lblMessage.Text = "Invalid file selected!"
            End If

            'Close/quit word 
            objWord.Quit(missing, missing, missing)
        Catch ex As Exception
            objWord.Quit(missing, missing, missing)
            Response.Write(ex.Message)
        End Try
    End If
End Sub

你可以试试

Dim objWord As Microsoft.Office.Interop.Word.ApplicationClass = CreateoBject("Word.Application")

一般来说，除非已经加载了word，否则在以这种方式创建word自动化对象时，我从来不知道这些对象是可见的

另外，您似乎正在向DOCUMENTS.OPEN函数传递一个ISVISIBLE参数，但我无法判断它的值是什么。如果为FALSE，则应将文档加载到一个隐藏窗口中，即使Word已打开，用户也无法看到该窗口。

在打开文档之前，您是否尝试将Visible设置为FALSE？感谢drventure-是ISVISIBLE导致了此问题。我在本地主机上运行它，但当我下载到doscontasp.net时，我发现服务器必须安装word，而他们没有。是否有解决方法，或者无法将word文档保存为html？
