Web Forms :: How To Use FileInfo With FileUpload
May 4, 2010
I have a detailsview which uploads 4 files and uses the objectcontainerdatasource. However, what I would like to do is once I got my files from the fileupload object is to cast it to FileInfo type.At the moment I can get hold of the files via detailsview but this is where I need help; as I have four files to upload, I want to save them to either an array, collection or list of type FileUpload or FileInfo (preferably FileInfo) along with two other properties and then to pass these values to a method that saves these files to a temporary location. This brings me to my next problem. In the method that saves the files to a temporay location, whilst I can do this with FileUpload, I want to return from this method the new file path location as a FileInfo type in order to use this in another method.

I have a site that access its images in a subfolder under the site root. I am checking for the file existance using he FileExist method of the FileInfo class like this -
Dim fi As FileInfo = New FileInfo(MapPath(img.ImageUrl)) If fi.Exists Then
What I want to implement is saving the images under different domain in order to make images available to other copies of this site. Problem is when I try to FileInfo(http address) I am getting an error saying "URI formats are not supported."How can I get FileInfo to work with URI ? is there a workaround ?

still really new to this, so I apologize if I explain my problem poorly. I'll do my best.I used this method to add an "active" class to my main navigation on another site. Now I'm using it to change the background image for a div based on the current page.Problem is, it's not working in this case. When I view the source I just see the tag sitting sitting there like it wasn't compiled:

And the rest:

i have a method that creates a thumbnail image from a fileinfo object thats an image.
so basically my method takes a FileInfo as a paramter, creates a nwe image, saves it and actually returns the FileInfo (no idea why - it doesn't really need to)
I want to delete the Fileinfo object (aka the file in the temp storage directory) after the image has been created but when i try to run fi.Delete() i get an error saying it can't because its being used by another process.
whats the solution to this? is it possible to delete this file in the same thread or am i going to have to create a service that runs on a schedule and cleans this folder.
What about creating a new fileinfo pointing to the current fileinfo and deleteing that?

Hopefully someone can give me some pointers to get this working properly.
I have a webpage which I would like the ability to upload files to be stored in a database. Here's the layout of the page:
[code]....
The update panel is configured as such:
ChildrenAsTriggers="True" EnableViewState="True" RenderMode="Block" UpdateMode="Always" Visible="True" Runat="Server"
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.

I have two folders in my asp.net web application in which I create new folders programmaticaly. The entire solution is under VSS source control. I was not able to manipulate these two folders programmably. For that, I gave {MACHINE}ASPNET user account full control over these two folders. Still, the "access denied to the path" error was coming. I saw that these entire folders were marked readonly. I tried to uncheck Readonly from explorer but not successfull, readonly check does not get removed. Also, if I copy files using method, the destinationn copied file becomes readonly. I have also tried File.SetAttributes (path,FileAttributes.Normal); but no success. How can I make the copied file not READONLY?

i set up Log4Net in a project, with the Log4Net.config file in "App_Data/config/Log4Net.config", and called the XmlConfigurator.Configure function with the following:
[Code]....
However, I the config file to be available in multiple projects, so moved it out to a solution folder (config/Log4Net.config).
Back in my MVC project, I added the config file as a linked file (and also set it to a "embedded" resource and "copy always" for the heck of it)
However I got no idea how the previous "var configfile = new FileInfo("????")" should read.
Tried it with and without Server.MapPath, using "Log4Net.config", "/Log4Net.config", "~/Log4Net.config", etc. No luck.
My guess it's because this Log4Net.config is not an actual file, but just linked.

I've been having several doubts with how fileupload control works internally. I've been trying to implement some kind of progress bar with iframes and such but I have noticed that when a local file is selected in the fileupload control and a postbackoccurs the file content is sent to the server wheter you choose save it or not.I have tested this with some examples and postback time seems to be the same in both cases, and the only difference is the time the servers needs to write the file on disk through the "FileUpload.SaveAs()" method.

On a page we have Fileupload control. It's not inside UpdatePanel. We use it to display pictures uploaded by user. Everything works fine until we save the state (button click causes postback). User adds picture and then click save. After that if we pick the file and try to upload it on server then PostedFile equals null. I know that FileUpload doesn't save it's file inside ViewState due to security reasons, but all we want to be able to use again FileUpload to upload further files after postback and so far it's impossible.

I have a fileupload control in the repeater control on my page. This page is almost six months old and the system was working fine. Suddenly, I started getting the error message : " 'FileUpload' does not contain a definition for 'HasFile' and no extension method 'HasFile' accepting a first argument of type 'FileUpload' could be found (are you missing a using directive or an assembly reference?) " when i tried to access the page. While in debug mode, the page works fine but when I access directly , it throws the error above.

Is there any way to use FileUpload control only for selecting a file and retrieving its path, without uploading its content?
