How To Detect The End Of Stream

Jun 29, 2010

1) I notice that the module gets it's data in chunks. This is problematic for me because I'm using a regex to find and replace. If I get a partial match in one chunk and the rest of the match in the second, it will not work. Is there any way to get the entire response before I do my thing to it? I have seen code where it appends data to a string builder until it uses a matches on an "" end tag but my code must work for more that just (xml, custom tags, etc). I don't know how to detect the End Of Stream or if that is even possible.

I have a working solution on an IIS6, which I made using this guide: FLV Flash video streaming with ASP.NET 2.0, IIS and HTTP handler

The app is basically a FLV Player, but streaming is essential to it.

Now, one of our customers is running IIS7 and the streaming doesn't work.

C# - How To Safely Read From A Stream

Nov 11, 2010

byte[] bytes = new byte[uploader.UploadedFiles[0].InputStream.Length];
uploader.UploadedFiles[0].InputStream.Read(bytes, 0, bytes.Length);
var storedFile = new document();
string strFullPath = uploader.UploadedFiles[0].FileName;
string strFileName = Path.GetFileName(strFullPath);
storedFile.document_id = Guid.NewGuid();
storedFile.content_type = uploader.UploadedFiles[0].ContentType;
storedFile.original_name = strFileName;
storedFile.file_data = bytes;
storedFile.date_created = DateTime.Now;


Reading from a stream in a single call to Read is very dangerous. You're assuming all the data will be made available immediately, which isn't always the case. You should always loop round, reading until there's no more data.

How should I change the above code to make it 'less dangerous'?

Check Whether Asf Stream Is Actually Playing?

Jan 18, 2010

I have a website built in ASP.NET 2.0 and a Windows Server 2003 server streaming live videos with Windows Media Services.

To play the content i usually embed a Windows Media Player in my page and make it open the publication URL (let's say, and it works fine.

The problem is that when no stream is playing, an empty stopped player appears and i don't like that

So i'd like to check in my (VB) code if there's actually something being streamed BEFORE i open the player, and display a 'no active stream right now, please try later' message instead.

Stream .flv Files From SQL Database?

Dec 9, 2010

I want to store .flv files in the database and not in the file system.

This is what I can do right now: Successfully convert .wmv and .mpeg to .flv with ffmpeg. Store images in SQL Server and show them on my page with an httphandler. Same with .avi and .mpeg videos. (It's up to the user's software if he can view it though) Play .flv files in the browser if the file is located in the file system and not in the database.

What I can't do is: Stream .flv videos to JW Player directly from the database. (Stored as binary data)

I've searched the internet for two days now but I can't get it to work. It feels as if I'm almost there though. The JW Player opens up and starts to "buffer", but nothing happens.

I know there's no easy answer but if anyone has done this before, or something similar, I'd like to know how you did. I feel I've got too much code to post it all here.

Stream .flv Videos From Database?

Dec 9, 2010

Has anybody been able to stream .flv videos from a database to a flash player?

I currently store videos (.avi, .mpeg, .wmv) and images in my database and I can stream these pretty good. I'm using a httphandler to do this.

But I can't get .flv videos to stream to the browser. If I don't upload the .flv file to the database but store it in the filesystem, everything works great.

Is it even possible to send a byte stream from the database to the flashplayer in the browser? I think it could have something to do with the headers of the .flv?

Can I do this or should I keep the videos in the file system?

MVC :: IE Cannot Display Xml Stream Containing Element?

Nov 2, 2010

How do I make it so any XML stream can be returned from a Controller Action without causing an error on the browser - Internet Explorer cannot display this feed?

When I return a ContentResult ( ContentType = "text/xml" ) that contains the xml elements <FeedSubmissionInfo>, <FeedSubmissionId> or <FeedType> I get an error in the browser - Internet Explorer cannot display this feed.

Currently, I do a String.Replace( "Feed", "Xeed" ) to get the XML to display in the browser.

public ContentResult InventoryFeed()
ContentResult cr = new ContentResult();
cr.Content = System.IO.File.ReadAllText("c:\downloads\amazon\response.txt");
cr.Content = cr.Content.Replace("Feed", "Xeed") ;

VS 2008 Stream.Read Error

Aug 31, 2010

We have a process that calles a url to pull an image (in this case a .tif image) and it calls this function which works most of the time but recently is getting errors. If I step through the While loop of a 92k file it gets to the end and then errors on the following line:

nBytesRead = stStream.Read(baBytes, 0, MAX_BUF)

I have added a Try/End Try statement which appears to work but is there a better option?
The error I get is:

System.IO.IOException: Unable to read data from the transport connection: The connection was closed.

Private Function ReadAsByteArray(ByVal stStream As Stream) As Byte()
Dim msBuffer As New MemoryStream()
Dim swWriter As New StreamWriter(msBuffer)

Dim nBytesRead As Integer
Dim baBytes(MAX_BUF) As Byte
nTotalBytesRead = 0
nBytesRead = MAX_BUF
While True

C# - Render Response Stream With Jquery?

Jan 9, 2010

MemoryStream export = new MemoryStream();
iCalendarSerializer serializer = new iCalendarSerializer(iCal);
return export;

so I am using the C# DDay.iCal library for exporting my calendars. Serialize takes in a "stream" so I passed it a memory stream. I now have a generic handler that calls the method that contains the above code.

public class CalendarHandler : IHttpHandler
private Calendar service;
private Membership membershipS;
public void ProcessRequest(HttpContext context)
service = new Calendar ();
membershipS = new Membership (null);
string userName = context.User.Identity.Name;
Guid userId = membershipS.GetUsersId(userName);
context.Response.ContentType = "text/calendar";
// calls the export calendar(the code that showed above that uses dDay ical.
var t = service.ExportCalendar(userId);
public bool IsReusable
return false;

So now I wrote the icalendar to the Outputstream. Now I have a jquery post that goes to this method and now I am not sure how to take the OutputStream result that the jquery post will get and make it popup with a save dialog box.

$.post('../Models/CalendarHandler.ashx', null, function(r)
return false;

Insert Anywhere A String Into The Response Stream?

May 7, 2010

I created a simple Http Module that starts a timer on the PreRequestHandler and stops the timer on the PostRequestHandler to calculate the time it took the page to load. I then create some simple html and write my results to Response.Write. Since I'm doing this in the PostRequestHandler it's adding my results after the </html> tag. That's fine for testing but I need in a scenario where the page needs to validate.

I can't seem to figure out how I could manipulate the Response object to insert my results before the </body> tag. Response.Write and Response.Output.Write don't have that flexibility and I couldn't see a way to work with the Response as a string. Am I missing something easy?
