MVC3 VB.NET Razor view Application... I have a view that uses a for each loop to display all the available courses. Next to each of these I would like to place a Html link to download that courses class handout file. Problem is I have not found anything on any forums about assigning the value to the hyperlink dynamically since it will vary with every iteration of the for each loop. I have coded the model to hold the file name associated with each class. Below is a snippet from the view..

View 5 RepliesI have an application where the admin user can create users and upload documents to the server for the created user to download.
When uploading a file it creates a folder using the userid as the folder name and saves in that folder within a folder called documents e.g. ~documents/77b29079-43d6-4520-bc34-77ae2af1b131/documentname.xls
The client then has to login and will see a list of available documents for that user only. The only problem is that if someone was to get hold of one of the urls to a document is can be downloaded without having to login.
Is there something I can do to stop access to these files?? I have tried editing the web.config file to only allow access to certain roles but i could still download a document without logging in.
<location path="documents">

I eyed VB.NET 2010 Express and created the damn app. It's up and running and it does what it's supposed to do (in v1). Now I'd like to distribute it for free while:
(1). Have a reliable way of knowing (and everybody can check this out) the number of downloads.
(2). The app cannot be passed from one user to another, but has to be downloaded from the reputable biz (there can be more than one biz) that accurately provides the number of downloads.
(3). I can have total control over the app (once it's downloaded by the users), that is if I want to inform the users of updates or whatever, or if I want to add some ad windows to the form I can do it whenever I want and how I please.
How do I do (1) to (3)? What am I supposed to read to do (3)? ADO.NET and ASP.NET? Any shortcut? What's the easiest way of doing it? I'm not sure I'm looking for a career in programming, for now I just want to take this app off my shoulders and go back to daydreaming.

View 3 RepliesI've just switched my code over that downloads data as bytes to use a WebClient. I add a header saying I will accept GZip and the site I'm downloading from sends me the data compressed. The problem is, how can I check to make sure it is compressed data before attempting to decompress it? It was much simpler when I was using a Web Request to check the response headers, but I'm having a little trouble checking the reponse headers with a WebClient. Does anybody out there accept compression with a WebClient?

View 8 RepliesI'm writing a small application that downloads some files over ftp, the incoming directory is monitored by FileSystemWatcher_Created, on creation I want to extract some text from the file and call another application with the text as parameters the problem I have is the FileSystemWatcher_Created procedure is triggered before the file has finished downloading, I could download it elsewhere and move into the monitored directory but some of the files may be quite large and Im wondering if there is an efficient way of waiting until the file is ready? along the same lines what is the best way to queue the tasks as there can be many files coming it at one time, I've looked at threading but would that be suitable for such a task as there will still be a bottleneck at the application called by FileSystemWatcher_Created ?
heres an outline of what im doing:
Private Sub FileSystemWatcher1_Created(ByVal sender As Object, ByVal e As System.IO.FileSystemEventArgs) Handles FileSystemWatcher1.Created
