How to load Dicom image from server (path contains https://)

How to load Dicom image from server (path contains https://)
Am using fo-Diocm library.
var image = new DicomImage(filePath);
if filePath is from local directory its working fine.
if filePath is from server (like https://example.com/filepath.dcm), its throwing 'Dicom.DicomFileException' saying that specified path value is not correct.
What is the right way to load DicomImage from server ??

AFAIK: Not at all. Obtaining DICOM Files through Web API is referred to as WADO (Web Access to DICOM Objects), and there is an open feature request in fo-dicom to support this, but it has been assigned quite a high priority.
However, the URL https://example.com/filepath.dcm does not adhere to WADO encoding, so maybe you cannot use a DICOM communication protocol to obtain the image (or you do not want to). But in this case, your task is simply "downloading a file from an URL" and not related to DICOM at all. After the download is completed, you have it stored locally, and can go on with local file access as you are used to.

Downloading a file in C# incorrectly returns files that is zero bytes long

So I'm trying to Download a file using WebClient class but the problem is that when the download is finished the file that should be downloaded is 0 byte, I tried uploading the same file without extension and than changing it after download but that didn't help. What Can I do? This is the code I Use
WebClient updateDownloader = new WebClient();
updateDownloader.DownloadFile(new Uri("http://zazaia.ucoz.com/SomeExeFile.exe"),
Application.StartupPath + "\\SomeFile.EXE");
And also have DownloadCompleted event handler which just shows MessageBox and Disposes the WebClient.

There is nothing wrong with the code you have shown and this should work. The problem is on the server which is not returning the file properly. Also make sure that the site you are querying doesn't require some authentication before being able to download files. In addition to that don't forget that a WebClient will not execute any javascript, so if the server relies on it to download the file, this will not happen.

Have you checked that your antivirus is not interfering? Sometimes an automatic scan will lock an executable file being downloaded until it passes. The client code itself looks fine however.
What about the server side? If is one of your own applications serving the download, then it may not be setting the MIME header or even not handling the download correctly at all

How to download big video files using WebClient class

I'm a newbie and I'm developing a windows application. I need to download a video file from my site and that's my issue here. I had designed a custom down-loader, through which I can download images, text files from my site. But I wasn't able download videos from my site. Could anyone please help me out..?
WebClient client = new WebClient();
client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(client_DownloadProgressChanged);
client.DownloadFileCompleted += new AsyncCompletedEventHandler(client_DownloadFileCompleted);
client.DownloadFileAsync(new Uri("http://mysitename.com/Videos/vid.mp4"), "c:\\movie.mp4");
I don't want to download by means of response content dispatch because my client wants me to download through custom browser.. so please let me know solutions from you experts.. thank you

I have tried to download a video file with WebClient and it works. My setup is as below:
I have a virtualdirectory(Video) in defaultwebsite (IIS) which has this video file.
I just use the below code to download the video file to C drive:
var client = new WebClient();
Uri address = new Uri("http://localhost/Video/wildlife.wmv");
client.DownloadFileAsync(address, #"c:\video.wmv");
Also note since you are downloading in Async fashion, wait for about a min for the operation to complete for the full file to be downloaded. Initially it shows 0 bytes but based on the size it takes some time to complete it.
UPDATE: If your server doesnt have the file mime type specified then just add to the collection of mime types that IIS can serve and you can download the file without any problem.
When adding MIME type the following values to be used are (for your scenario):
File Extension: .mp4
MIME Type: video/mp4
To add mime types in IIS follow these links:
For IIS 4,5
For IIS 6
For IIS 7

This sounds more like a server issue, but if you are doubting your code, you may want to try download sync (I have had some issues in the past downloading async). Another way is to use the WebRequest class. If this server is very remote, try pinging beforehand. I think that you should also check to make sure the file is on the server, and if the file is really big, you should check to see if the file finished uploading.

How do I make WebClient.DownloadFile() work with xnb, xgs, xsb, xwb files?

I'm creating an Updater program in C# for my PC game that basically sends an Http message to the server to find out what the latest version of the game is. If there is a newer version, it downloads the necessary files. To download the files I used the WebClient.DownloadFile() method. There are a few posts on the forums detailing problems with this method but none of them are quite like mine.
I use the method like this:
WebClient webClient = new WebClient();<br/>
webClient.DownloadFile(sOriginFile, sDestinationFile);
I immediately ran into a problem downloading any files with the following extensions:
.xnb
.xgs
.xsb
.xwb
I would get an exception stating "The remote server returned an error: (404) Not Found."
So as an experiment I added 3, more common, files to the same directory.
.txt
.doc
.jpg
and the DownloadFile() method worked perfectly for those files. Does anybody know why this method isn't working for the first 4 files types but works fine with the last 3?
Also I tried WebClient.DownloadData() and HttpWebRequest.GetResponse() (after setting up the request), I even tried reversing the extension name on the server (.bnx), but no matter what, I would get the same exact exception.
If anybody really wants to tackle this, here are links to 2 sample files (I tried to post all 7 sample files but Stack Overflow only allows me to post 2 links):
http://www.facepuncher.com/Versions/CastleAbra/1.1/Sample.txt
http://www.facepuncher.com/Versions/CastleAbra/1.1/UiCursor.xnb

Most likely the MIME-Settings for the file types you mention are set up incorrectly in IIS. Go to IIS Server Mananger -> MIME-Settings and add the file-types accordingly.
Probably a better idea to transfer any filetype would be to download only files like
file.xnb.dat
file.xgs.dat
and rename them locally.

C# upload file to server - both client and server side

I'm a C# game programmer with little web development experience.
I need to upload a small file (25-100 or so bytes, depending on it's content) to a server. This is on the Windows Phone 7 using XNA. The target server is fairly limited and only supports PHP and classic ASP.
Since the CF on the WP7 only has access to a limited subset of networking commands, it's looking like an HttpWebRequest GET aimed at a script that saves the file will be the best option. The data I'm sending is small in size, and should be able to be passed as a parameter in the url.
I've been searching but have yet to find a complete example of this, which handles both the client and server side script (mainly the latter). This is close to what I'm looking for, except it has no mention of the server side script: Upload files with HTTPWebrequest (multipart/form-data)
The closest that I got was this: http://www.johny.org/2007/08/upload-using-c-as-client-and-php-as-server/
But when attempting to use it I get an unhandled exception: "The remote server returned an error: (405) Method Not Allowed". This method seems the most promising so far, but I've yet to be able to debug this.
Unfortunately, I have a short amount of time to implement this, and as I said only a passing familiarity with web development. I'm not worried about maximum security or scalability as this is a temporary measure to collect feedback internally. Basically, I just need the quickest thing that works. ;)
Any help would be fantastic!

I've solved it. First off, PHP wasn't supported on my server (just now learning that PHP and ASP are can't be used on the same server, depending on whether it's on Linux or Windows - like I said, web development noob here!). I switched to ASP and, after digging through the docs, wrote this script:
<%
dim theData, theFileName
set theData=Request("data")
set theFileName=Request("filename")
dim fs,tfile
set fs=Server.CreateObject("Scripting.FileSystemObject")
set tfile=fs.CreateTextFile(Server.MapPath(theFileName+".txt"))
tfile.WriteLine(theData)
tfile.Close
set fname=nothing
set fs=nothing
set theData=nothing
set theFileName=nothing
%>
This C# code uploads the file:
const string cAddress = "http://site.com/folder/upload.asp";
string fileName = foo;
string data = bar;
string address = cAddress + "?filename=" + fileName + "&data=" + data;
uploadRequest = (HttpWebRequest) HttpWebRequest.Create(address);
uploadRequest.Method = "GET";
uploadRequest.GetResponse();
Hope this helps someone else looking for an example of how to do this!

But you have the METHOD as GET instead of POST. You can't upload a file to a website by passing the file path to the Query String.
