FileUpload control does not save file

Question

I am trying to upload a file and cannot get it to work. I have the correct url for the site and sub-folder. I have tried fileUploader.FileName and fileUploader.SaveAs as well. None seem to work. It is not in an UpdatePanel. Any ideas?

Code behind:

Protected Sub uploader_click(sender As Object, e As EventArgs) Handles btnUpload.Click
 If fileUploader.HasFile Then
    Dim _path As String = Path.Combine("{path to site and folder}", Server.HtmlEncode(fileUploader.PostedFile.FileName))
    Try
      fileUploader.PostedFile.SaveAs(_path)
    Catch ex As Exception
      Response.Write(ex.ToString)
    End Try
 Else
  Response.Write("No File")
 End If
End Sub

New code, I need to get parent folder to expose the sub folder:

  Dim filePath = Path.GetFileName(fileUploader.PostedFile.FileName)
  Dim _path As String = Path.Combine(Server.MapPath("~"), "subfolder", filePath)

_path = \\{server blah}\{site}\webroot

Now no error, but no file uploaded either???

It does not print anything to the `Reponse.Write`, it does not save file. — OneFineDay, Nov 28 '13 at 03:16
Can u put a breakpoint at the `IF` and follow it step-by-step to see what is happening? — Yuriy Galanter, Nov 28 '13 at 03:19
If I test it on localhost all works well with local folders. — OneFineDay, Nov 28 '13 at 03:21
If its working fine on the local host and not working when hosted, then the most probable reason would be file permissions. Also right click the page to view source after submitting the file. You may not see the error written by response.write since the page conatins a lot of html and all. — Subin Jacob, Nov 28 '13 at 04:28
I am now getting an error `Could not find a part of the path '\\{server blah}\{site}\{subfolder\{filename}'.` and this looks just like the path should be - what gives? — OneFineDay, Nov 28 '13 at 06:07

You have to set File Permissions if you are on Hosting provider. If you are using a shared hosting, then there would be options to do it. If you have access to IIS, then you can do it yourself.

I bet not, I will look into it. – OneFineDay Nov 28 '13 at 04:09
I do have access to IIS, what do I need to do? – OneFineDay Nov 28 '13 at 04:09
If you are sure, this is n't the problem, then turn off custom error mode in web config and see the error if any. – Subin Jacob Nov 28 '13 at 04:12
I enabled this folder in the Directory Browser - it was disabled. No change after doing this though. – OneFineDay Nov 28 '13 at 04:17
Do `fileUploader.HasFile `? – Subin Jacob Nov 28 '13 at 04:21
Not sure what you mean by your last comment. I don't know how to debug a published site. The localhost works fine. – OneFineDay Nov 28 '13 at 04:23
How do I check if it is `ReadOnly`? – OneFineDay Nov 28 '13 at 04:29
For which user did you give permission? you have to give permission to IIS users. Giving permission to any other user won't make any sense. Also try giving permission to all users. – Subin Jacob Nov 28 '13 at 04:29
I don't understand how to set file permissions, sorry new to IIS stuff. – OneFineDay Nov 28 '13 at 04:30
Do you mean on the file itself? – OneFineDay Nov 28 '13 at 04:31
If you trying to access a file, then file. There won't be any error because your code is safe inside try catch block. remove that try catch and see the error. The error will take you to the right direction. If the site is hosted and not private give the link, I can check it . – Subin Jacob Nov 28 '13 at 04:39

You have to set permission to IIS IUSERS .. http://www.asp.net/mvc/tutorials/deployment/deployment-to-a-hosting-provider/deployment-to-a-hosting-provider-setting-folder-permissions-6-of-12 – Subin Jacob Nov 28 '13 at 04:49
In `IIS` the `.Net Roles` have been disabled, and the `.Net Users` has an error and does not load. – OneFineDay Nov 28 '13 at 05:06

Use `Server.MapPath("subfolder")`. I hope The the subfolder is virtual path. ie. www.yourdomain.com/subfolder – Subin Jacob Nov 28 '13 at 06:11

Modify your third line like this

Dim _path As String = Path.Combine(Server.MapPath("{Relative url of your folder within your project}"), Server.HtmlEncode(fileUploader.PostedFile.FileName))

Relative URL should be something like this:

"~/folder/Folder2//"

It finally worked, must be delay between publish and using the new files - cloud based. It is working as expected wit this path.

If fileUploader.HasFile Then
  Dim filePath = Path.GetFileName(fileUploader.PostedFile.FileName)
  Dim _path As String = Path.Combine(Directory.GetParent(Server.MapPath("~")).FullName, "subfolder", filePath)
  Try
    fileUploader.PostedFile.SaveAs(_path)
  Catch ex As Exception
    lb.Text = ex.Message
  End Try
Else
  lb.Text = "No File!"
End If

Thanks for the help everyone.
