Two different web servers I have tried, here they are
Here is the first on a remote web server. I think this is probably a
permissions error and am trying to figure out exactly which ones because
read/write are granted...
File upload failed: System.Net.WebException: The remote server returned an
error: (405) Method Not Allowed.
at System.Net.HttpWebRequest.CheckFinalStatus()
at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)
at System.Net.HttpWebRequest.GetResponse()
at myProject.ForumSubmit.uploadFile(String strAttachFile) in
C:\Inetpub\wwwroot\myProject\ForumSubmit.aspx.cs:line 181
Here is the second connection which is just to another folder on my
computer...I also have folder with read/write access so I am not sure why
access is denied.
File upload failed: System.UnauthorizedAccessException: Access to the path
"C:\public\tempFiles\work\docs\myDoc_.doc" is denied.
at System.IO.__Error.WinIOError(Int32 errorCode, String str)
at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess
access, FileShare share, Int32 bufferSize, Boolean useAsync, String msgPath,
Boolean bFromProxy)
at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess
access, FileShare share)
at System.IO.File.OpenRead(String path)
at myProject.ForumSubmit.uploadFile(String strAttachFile) in
c:\inetpub\wwwroot\myProject\forumsubmit.aspx.cs:line 170
I'm not sure why it's not working or why a folder needs certain access.
Whenever I try uploading files from my computer to any forum online they
don't need to see my folders as having shared access. I just choose the file
click Submit and it works fine for them. So why not here?
BTW, I am working with VS.NET, IIS5, and on a winxp system. I am trying to
connect to a remote web server a friend set up in the first example and from
myself to myself in the second. This upload file code will be used for a
website forum I am creating so that users can attach pictures or files with
their submissions. Let me know if you need any more info and thanks for your
help.
