I'm trying to make a Game Launcher, that looks through all of the game files located on my Webserver on the internet, and updates the local files, depending if the "If modified since" value has changed.
Im using C# with Windows application, and my code does works to access some files, but not all. Files like .DLL and files without and extension (.FILE) doesn't get allowed access, which I don't understand.
I've tried to add this MIME type to my Web.config, which solves the access of some files, but not all of them.
<mimeMap fileExtension="*" mimeType="application/octet-stream"/>
Basicly, I need a way where I can access any file on my webserver, through HttpWebRequest/Response in a C# Windows Application.
If you are using IIS, probably you need to add the corresponding MIME-types in the IIS Manager as well.

In my web-app (WebPages, C#.NET) I have a drag and drop file box where user's can drag files from windows explorer and, once dropped, it will save in a given location on a shared drive. This part is working fine. The box looks something like this:
The problem is, that it also reads files from the same directory and my user's would like to be able to open the files from this interface on dblclick. I have written an ajax request with jquery (the ajax, too, is working fine), but I can't seem to get the files to open on the user's machine no matter what I try.
Most references I try and look up point me towards System.Diagnostics.Process.Start(#"<directory goes here>") but this doesn't really do anything. It will open some process on the server side, but nothing opens, either on the server or on the user's machine.
What they'd like to do, for instance, is double click 'Hazcom.xls' and it would use the default associated application to open the file. In this case, of course, Microsoft Excel.
Is this even possible or am I chasing a wild goose here?
Sources I've Tried:
Open file with associated application
http://www.csharp-examples.net/open-file-with-default-application/
How can I open Windows Explorer to a certain directory from within a WPF app?
c# open file with default application and parameters
There have been a few more sources I've tried, as well, but they're all pretty much in the same vein as these.
Additional Info:
The internal Intranet application runs on a server using IIS 8
The solution is desired to be opened on the user's machine and not, say, the server itself.
The path to the files is dynamically changing depending on what they have loaded into the interface.
Though, I'm not expecting this to be a solution viable for client side (jquery) I'd be happy to look into that if that's the only solution available.
I'd also settle for simply opening the file location, instead of the actual file itself, but I've had no luck with this either, for what looks like the same reasons as the original problem.
I recently added a way for my web application (ASP.NET written in C#) to go to a folder which contains a bunch of spreadsheets and import them into SQL server tables. I set the folders and file names using an admin table so it knows how to handle each file and which table they should go to etc. It even keeps track of the file dates and times so it ignores anything that isn't new since the last time it imported them. Very cool but it only works on my development machine, most likely because the path is easily recognized there.
I'd like others to be able to do this but I can't seem get the web application to access a pre-arranged path on the users local machine. Now I'm assuming this is normal (we shouldn't be able to have a web application reach into someone's machine and grab files!) but is there some way to either do it using a known path or by having a user select the local folder? Is it possibly done more easily if I put the files in a folder within the site?

If I understand your question correctly, the approach is that you want a user to type in a local file path and you process it.
This will not work through a website. And from a security perspective this is very wise as you point out. So unless you install some client application on the local machine it is not possible.
You will need a file-upload dialog and have the user explicity locate the files for you, click upload and process them on the server.
Some other strategies here:
https://developer.mozilla.org/en-US/docs/Using_files_from_web_applications
but it still requires the user to select them manually.
I'm trying to find a way to write "meta" information to EXE files that are uploaded to my IIS/ASP.NET web service. Here's a little bit of background:
I need to write one arbitary string into the properties
It'll be URL that I write as "metadata", if that matters
Example: https://example.com/someFolder/someOtherFolder
The files are mainly installers originally created by InnoSetup
The web server is running IIS 7.5 with ASP.NET on top of Server 2008 R2 (Standard)
Why am I trying to write this information?
Ultimately the EXEs are made available to users for download. When the application runs, it needs to know the web URL in order to execute properly. Currently we have a plain text box where the user can input the URL, but that has proven to be error prone (despite prompting/error checking/...)
Why can't I just write the metadata in the EXE when it's created?
I could do that, but the EXE could be uploaded to a variety of different servers, each with their own unique URL "metadata". I'm trying to avoid creating a separate build script for each server.
Why not just create a *.zip file with the *.exe and an extra piece of metadata?
I suppose I could do that too -- but then the user would have to actually unzip the download so that the real installer could read the metadata. I had something similar to this before and most people never unzipped the full download and that posed its own problems.
So is this even possible? I guess as a last resort I could use the uploaded EXE to create a new EXE, but I'm trying to avoid doing that (gets into problems with signed EXEs, etc.)
We are building an application that will only be used within our infrastructure. We have videos on a windows file share which we want to play within the app. The videos are working when they are embeded in the app but as some of them are so big we want to move them out.
I am trying to reference the videos using an smb:// url but that doesn't seem to work.
I am also trying to reference them using a file:// url to no avail. I can see the folder from the dev mac.
Should this work or do I need to do more work to make it happen? Such as streaming?
iOS is not able to access any kind of shared directory (smb:// or file://), you will have to add code to your app to connect and transfer the files yourself if you want to use a shared directory like that.
But iOS can access web servers, so if you can set up a simple http server (Apache or IIS), and serve the files using a http protocol, it should work just fine.
I have a website that occasionally needs to have a handful of the tables in its database updated. The updates come from another system that exports to comma delimited text files. I can then either FTP the text files to the web server, send them in through an admin upload page, or manually log in to Remote Desktop to download the text files. I have all my C# code written to parse the files, check the database contents, and decide what to do.
Should I code the sync logic to be part of a file upload page, protected in the admin section of the site or should I create a Windows Service that constantly looks for files to process in a particular directory that I can drop files in through FTP?
I have used Windows Services in the past and they have worked great, but if I ever have to make a change to the code it can take longer than it would if I just had to modify an ASPX.
Are their security benefits one way or another?
Performance benefits?
ASPX page wins the "ease of maintenance" category.
I would create a Windows Service to watch a secure folder and use a directory watcher to look for new files. Since the files are coming from another system, it is asynchronous in nature, and it is much more performant to have a Windows Service running separately to watch for updates as they happen. It can also parse the files and update the database for you.
Depending on who maintains the remote system, the easiest way is to grant permission to the service to access the files on a secure, shared folder. Then you won't need to do anything manually.
