Saving Attachments from Exchange 2003 to Local File System Using WebDEV and VB.NET RRS feed

  • User1008945111 posted

    I'm trying to download the attachments related to any given email in a specified users inbox and save them to the local file system.  I have it inserting the message body, subject and sender's address into a database, then if there are any attachments, I get the list of attachments and do a get on each file path, returning the file content.  From what I have researched the file content is returned to me as binary data, which I then need to stream to a created file on the server.

     So below is my attempt at streaming the data and saving the file, I think I am close, as it does create the file, and there is a bunch of illegible stuff in it if I open it with a text editor.  It's not right though, the file that is saved is not valid.  If I try to save an excel file for example, excel just tells me there it is not a recognized format.  Images opened with MS fax viewer gives me "No Preview Available".  Some guidence would be greatly appreciated.

    Try this



    Dim xmlstr2 As String = xmlhttp.responseText
    Dim fs As New FileStream("
    C:\" & fname, FileMode.Create)
    Dim w As New BinaryWriter(fs)



    Dim _ResponseBody() As Byte = xmlhttp.responseBody
    My.Computer.FileSystem.WriteAllBytes("C:\Attachments\" & fname, _ResponseBody, False)
