• Why is HttpContext.Current.Session available in HttpModule but not in Response.Filter?

  - by Abtin Forouzandeh

  I have written an HttpModule that adds a response filter. The filter is capturing page output and storing it in a session variable. I am able to access HttpContext.Current.Session in my HttpModule. The HttpModule is handling the PostAcquireRequestState event. I am still able to access HttpContext.Current.Session in the PostAcquireRequestState event. I am adding a custom stream that inherits from Stream to Response.Filter HttpContext.Current.Session is null when accessed from the Stream.Write method. Everything worked fine when using an InProc SessionState. However, I now must use StateServer. Using StateServer, the code is now broken. Any ideas?

• How can I suspend \ resume the video caputre operation in v4l2 ?

  - by Ita

  Hi, I use the v4l2 api for video capture and image applying image processing algo' on each frame. I wish to be able to suspend the video capture. I see that there are 2 options for ioctling (new verb, its gonna catch) the stream. VIDIOC_STREAMON, VIDIOC_STREAMOFF will start and stop the stream. Is there a way to suspend \ resume it? Is this even necessary, or can I just use the start and stop controls with no extra processing time spent on creating the stream all over again ? Thank you for your time, Itamar

• Silverlight Video Player that plays .MP4 & .FLV

  - by YeahStu

  I am currently using the Silverlight 2 Video Player to stream videos. I have been very pleased with it but it only seems to stream .WMV files. Does anyone know if there is a good Silverlight video player that will stream other types of video files, especially .MP4 & .FLV? I would be happy to use Silverlight 3 if necessary. EDIT: Because I like this player and have not found a great option, I am considering encoding files as I receive them so that they will always be streamed later as a .WMV. Unless I determine a good player (I am considering flash at this point), I will have to go down this road.

• Is it possible to set ContentType for a WCF WebGet method?

  - by James Cadd

  I'm working with a WCF restful/http method that returns a stream of image data. I want to make sure that the content type is marked as "image/png". The method is defined as: [ServiceContract] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] public class TileImageService { [WebGet(UriTemplate = "{id}")] public Stream GetTileImage(string id) { Bitmap bmp = new Bitmap(173, 173); Graphics g = Graphics.FromImage(bmp); g.Clear(Color.Blue); g.DrawString(DateTime.Now.ToLongTimeString(), new Font("Chiller", 20), Brushes.White, new PointF(10, 10)); g.Flush(); MemoryStream ms = new MemoryStream(); bmp.Save(ms, ImageFormat.Png); ms.Seek(0, SeekOrigin.Begin); return ms; } } In Firefox it looks like the content type is marked as application/octet stream. Is there a way to change the content type?

• Verifying serialisation streams when used for messaging

  - by Nick

  I want to add distributed messaging to some applications. One target would be embedded and the other applications would be running on Windows. I'm thinking of having a connection manager, to which all of the applications would connect and communicate. I only need some simple kind of RPC mechanism. I've looked at Google Protocol Buffers, but I don't really like the idea of code generation. I'd rather use serialisation and somehow verify the format of the serialised stream. I.e. Perhaps send metadata about what the stream would contain so that each endpoint can verify it is reading the correct version. Does anyone know of any examples of this? Perhaps the message format could be read from a file which all the applications read to verify the stream format?

• Is there such a thing as a C# style extension method in C++ ?

  - by Gary Willoughby

  I'm currently learning C++ and i run into the simple problem of converting an int to a string. I've worked around it using: string IntToString(int Number) { stringstream Stream; Stream << Number; return Stream.str(); } but though it would be more elegant to use something like: int x = 5; string y = x.toString(); but how do i add the toString() method to a built in type? or am i missing something totally fundamental?

• What are my options for streaming for silverlight?

  - by Will I Am

  I would like to implement limited scope streaming (LAN, multicast, even broadcast) where the client is implemented in silverlight. More importantly, I would like to stream from a desktop OS, not a server OS. As a result, I can't use the MS media server, which I believe requires WS2003 or WS2008. Ideally the solution would have some sort of API so I can plug in or provide a custom frame source. If I need to encode my own video, how can I encode using H.264 or another Silverlight supported codec? if I need to implement my own server, where can I find information about how a client starts to receive a stream? thank you! I know, it's a lot of questions, but it basically boils down to "how do I stream from a non-server OS?"

• How to save an image in it's original format?

  - by Patrick Klug

  I am trying to figure out how I can get the original format of an image so that I can store it with the same encoding. It seems that the only way to save an Image is by using a BitmapEncoder but I don't know how I can get the correct format from the image. Example: Clipboard.GetImage() returns a InteropBitmap which doesn't seem to contain any information about the original format. I also tried using an Extension method: public static void Save(this BitmapImage image, System.IO.Stream stream) { var decoder = BitmapDecoder.Create(image.StreamSource, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default); var encoder = BitmapEncoder.Create(decoder.CodecInfo.ContainerFormat); foreach (var frame in decoder.Frames) { encoder.Frames.Add(BitmapFrame.Create(decoder.Frames[0])); } encoder.Save(stream); } but the problem is that a) the ImageSource is not always a BitmapImage (Clipboard.GetImage()) for example and b) the image.StreamSource can be null in some cases (seems to be when the image is loaded via a relative Uri)

• Problem in serializing

  - by Harun

  Hello Guyz, Presently I need to serialize one of my object which contains more my own classes object. But the problem is I dont want to save it in a file and then retrieve it into memory stream. Is there any way to directly serialize my object into stream. I used BinaryFormatter for seializing. First I used a MemoryStream directly to take serialize output but it is giving error at time of deserialization. But later when I serialize it with a file then close it and again reopen it , it works perfectly. But I want to take it direct into stream because in my program I need to do it frequently to pass it into network client. And using file repeatedly might slow down my software. Hope I clear my problem. Any Sugetion ?

• How to host your own http-like server using ServiceHost?

  - by Ole Jak

  I use ServiceHost for hosting WCF cervices. I want to host near to my WCF services my own tcp programm (like WCF service but with out WCF) for direct sockets operations (like lien to some sort of broadcasting TCP stream) I want to use ServiceHost for somehow simplyfiing proces of creating my TCP sender\listener, to somehow control namespaces (so I would be able to let my clients to send TCP streams directly into my service using some nice URLs like www.example.com:34123/myserver/stream?id=1 or www.example.com:34123/myserver/stream?id=222 and so that I will not be bothered with Idea of 1 client for 1 socket at one time moment, BTW I realy want to keep my WCF services on the same port as my own server or what it is...) Can any body please hrlp me with this?

• Using FileSystemWatcher in detecting a xml file, using Linq in reading the xml file and prompt the results error "Root Element is Missing"

  - by GrayFullBuster

  My application is already working it can detect the xml file and prompt the content of the xml file but sometimes it will prompt "Root element is missing", and sometimes also it is okay but when I open the xml file, it is ok, it has contents on it. How to solve this issue. Here is the screenshot of the error: Here is the code: private void fileSystemWatcher_Created(object sender, System.IO.FileSystemEventArgs e) { string invoice = ""; using (var stream = System.IO.File.Open(e.FullPath, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.ReadWrite)) { var doc = System.Xml.Linq.XDocument.Load(stream); var transac = from r in doc.Descendants("Transaction") select new { InvoiceNumber = r.Element("InvoiceNumber").Value, }; foreach (var i in transac) { invoice = i.InvoiceNumber; } } MessageBox.Show(invoice); fileSystemWatcher.EnableRaisingEvents = false; } The error goes here var doc = System.Xml.Linq.XDocument.Load(stream);

• Data persistance with BufferedReader and PrintWriter?

  - by Nazgulled

  I have this simple application with a couple of classes which are all related. There's one, the main one, for which there is only one instance of. I need to save save and load that using a text stream. My instructor requirement is BufferedReader to load the stream and PrintWriter to save it. But is this even possible? To persist a data object/class with a text stream? I know how to do it with and object, using serialization. But I don't see how am I supposed to do it using text streams. Suggestions?

• C# private (hidden) base class

  - by Loadmaster

  It is possible to make a C# base class accessible only within the library assembly it's compiled into, while making other subclasses that inherit from it public? For example: using System.IO; class BaseOutput: Stream // Hidden base class { protected BaseOutput(Stream o) { ... } ...lots of common methods... } public class MyOutput: BaseOutput // Public subclass { public BaseOutput(Stream o): base(o) { ... } public override int Write(int b) { ... } } Here I'd like the BaseOutput class to be inaccessible to clients of my library, but allow the subclass MyOutput to be completely public. I know that C# does not allow base classes to have more restrictive access than subclasses, but is there some other legal way of achieving the same effect?

• Need help setting up json array

  - by torr

  A database query returns several rows which I loop through as follows: foreach ($query->result() as $row) { $data[$row->post_id]['post_id'] = $row->post_id; $data[$row->post_id]['post_type'] = $row->post_type; $data[$row->post_id]['post_text'] = $row->post_text; } If I json_encode the resulting array ($a['stream']) I get { "stream": { "1029": { "post_id": "1029", "post_type": "1", "post_text": "bla1", }, "1029": { "post_id": "1030", "post_type": "3", "post_text": "bla2", }, "1029": { "post_id": "1031", "post_type": "2", "post_text": "bla3", } } } But the json should actually look like this: { "stream": { "posts": [{ "post_id": "1029", "post_type": "1", "post_text": "bla1", }, { "post_id": "1030", "post_type": "3", "post_text": "bla2", }, { "post_id": "1031", "post_type": "2", "post_text": "bla3", }] } } How should I build my array to get this json right?

• Content Types in browsers, can we use the Mime??

  - by SoLoGHoST

  Ok, I am wondering which mime types are dangerous in browsers? That is to say setting the Content Type to that mime type?? Which mime types, if any would pose a security risk?? I am noticing that many forum software, when uploading files, use the application/octet-stream for any files other than images and place that into the Content Type of the header. I am wondering why don't they place the actual mime-type instead into the Content Type? Are there security risks involved with this? So far I have used text/css, text/plain, audio/mpeg, and many others and haven't noticed any difference between application/octet-stream and these others. Does anyone out there know the exact difference, and what makes application/octet-stream any better, or any worse...to use for the Content Type?? Thank You :)

• What is the best strategy for a streaming screen capture application ?

  - by The_AlienCoder

  Ok Ive figured out how to do a screen capture of my desktop using Windows Media Encoder 9 + SDK and saving it as a movie on my hardrive. But now I want to take my project further and stream a realtime screen capture of my desktop . The idea is that users accessing my asp.net website will be able to view whatever Im doing on my desktop in real time via the video streaming from my computer. I really dont need the source code just the best strategy, procedure and server requirements.How will users access the streaming video on my website? Will it work on my godaddy shared hosting account or at what point will I need an upgrade? Will I be saving the stream to a file on the server for users to access or is there a way to stream directly ? I just need someone to point me in the right direction...

• iPhone SDK SDL_openAudio with Multitasking Support

  - by brokedid

  Hello, I'm playing audio from a Online Live RTPS Stream with ffmpeg(because Apple doesn't support rtsp live streaming). Now I would play my Stream in the background. I started a thread in the background and registered the music for Background support. When the Application is entering in Background the NSThread is paused, and then Resuming after returning from background. If I start playing a Music (MP3-Stream) in the Application which use official Apple Frameworks then when the App is entering Background both Streams are played. What can I do to fix this?

• F# match char values

  - by rwallace

  I'm trying to match an integer expression against character literals, and the compiler complains about type mismatch. let rec read file includepath = let ch = ref 0 let token = ref 0 use stream = File.OpenText file let readch() = ch := stream.Read() let lex() = match !ch with | '!' -> readch() | _ -> token := !ch ch has to be an int because that's what stream.Read returns in order to use -1 as end of file marker. If I replace '!' with int '!' it still doesn't work. What's the best way to do this?

• Android 3.2 HTTP streaming

  - by user1281053

  I'm trying to create an app to stream live TV. Currently the problem I'm facing is that after say 10 minutes of playing, the video will freeze but the audio will carry on. This is on a 1.3mbps stream. I also have lower streams, such as a 384kbps stream, that might last an hour or so, but will still do the same. I've tested this with a local video, that is high quality (file size is 2.3gb) and that has no lag and doesn't freeze at all, so it must be something to do with the way HLS is streamed to android. Does anyone have any idea on how to solve this problem? Thanks
