How can I open MS Word document using ASP.NET

[John Wen]

Hello

First of all, I can open the MS Word document using VB.NET. However, I cannot do the same in ASP.NET (error message is "Access is denied") using the same method of VB.NET. What is wrong? Perhaps it might be the problem of permission, but I have already added the ASP.NET User account for the Word.Application from the registry.

How can I open MS Word document using ASP.NET?

Best regards

Translation of the above post. Seems to work fine.

        Try
            Dim stream As FileStream = File.Open("d:\word.doc", FileMode.Open) 'replace the location with your word doc.

            stream.Position = 0

            ' Now read s into a byte buffer.
            Dim bytes() As Byte = New Byte(stream.Length) {}
            Dim numBytesToRead As Integer = CType(stream.Length, Integer)
            Dim numBytesRead As Integer = 0
            While numBytesToRead > 0
                ' Read may return anything from 0 to numBytesToRead.
                Dim n As Integer = stream.Read(bytes, numBytesRead, numBytesToRead)
                ' The end of the file is reached.
                If n = 0 Then
                    Exit While
                End If
                numBytesRead += n
                numBytesToRead -= n
            End While
            stream.Close()

            Response.Clear()
            Response.ContentType = "application/word"
            Response.AddHeader("Content-disposition", "filename=output.doc")

            Response.OutputStream.Write(bytes, 0, bytes.Length)
            Response.OutputStream.Flush()
            Response.OutputStream.Close()
            Response.Flush()
            Response.Close()
        Catch ex As Exception
            Throw ex
        End Try

Hello

See the following codes, then why "Access is denied"? I do want to know the reason of "Access is denied". It is because the same code can apply to VB.NET. Please help.

Regards

  Dim oWord As New Word.Application
        Dim oDoc As Word.Document

        oDoc = oWord.Documents.Open("c:\rubbish\resume.doc")
        Response.Write("<font color=blue>" & oDoc.Content.Text & "</font>")

Hi John

I don't know how you add ASPNet account to Word. As web-based application is running under a process identity, I think a better way is to impersonate your ASP.Net application's process identity to use a higher privilege account. This can be done in Web.config.

For more idea about process identity, please visit my blog (though not 100% fit your question) at http://www.biswaretech.com/blog15.aspx
