  • C# Get Keys from a Dictionary<string, Stream>

    - by alex
    Suppose I have a Dictionary like so: Dictionary<string, Stream> How can I get a list (or IEnumerable or whatever) of JUST the Keys from this dictionary? Is this possible? I could enumerate the dictionary, and extract the keys one by one, but I was hoping to avoid this. In my instance, the Dictionary contains a list of filenames (file1.doc, filex.bmp etc...) and the stream content of the file from another part of the application.

  • How do I make a daemon into a stream in PHP

    - by Itay Moav
    I have a daemon (written in C, but I assume it does not really matter) which outputs messages with printf, and can get input and do stuff with this input (again, not really important what, but he sends those messages to a different machine to be saved there in the DB). My question, how can I make this daemon to be a stream in PHP, so I can hook the input/output of, for example, file_put_contents to this stream.

  • Stange stream of HTTP GET requests in apache logs, from amazon ec2 instances

    - by Alexandre Boeglin
    I just had a look at my apache logs, and I see a lot of very similar requests: GET / HTTP/1.1 User-Agent: curl/7.24.0 (i386-redhat-linux-gnu) libcurl/7.24.0 \ NSS/3.13.5.0 zlib/1.2.5 libidn/1.18 libssh2/1.2.2 Host: [my_domain].org Accept: */* there's a steady stream of those, about 2 or 3 per minute; they all request the same domain and resource (there are slight variations in user agent version numbers); they come form a lot of different IPv4 and IPv6 addresses, in blocs that belong to amazon ec2 (in Singapore, Japan, Ireland and the USA). I tried to look for an explanation online, or even just similar stories, but couldn't find any. Has anyone got a clue as to what this is? It doesn't look malicious per say, but it's just annoying me, and I couldn't find any more information about it. I first suspected it could be a bot checking if my server is still up, but: I don't remember subscribing to such a service; why would it need to check my site twice every minute; why doesn't it use a clearly identifying fqdn. Or, should I send this question to amazon, via their abuse contact? Thanks!

  • IIS7 Binary Stream Error

    - by WDuffy
    I'm struggling to understand the problem I'm seeing so please accept my apology if the question is vague. I'm running a classic asp app in IIS7 and everything seems to work fine except for one issue that has me stumped. Basically, files can be downloaded from the server which is done using the sendBinary method of Persits ASP Upload component. This component works fine for uploading etc it's just the downloading I have a problem. The strange thing is, I cannot have a pure asp page that serves the binary file. Everything works fine in II6, but in II7 there is a strange problem. For example this does not work. <% SET objUpload = server.createObject("Persits.Upload") objUpload.sendBinary "D:\sites\file.pdf", true, "application/octet-binary", true SET objUpload = NOTHING %> However, if I put anything in front of the asp code the file is served fine. serve this <% SET objUpload = server.createObject("Persits.Upload") objUpload.sendBinary "D:\sites\file.pdf", true, "application/octet-binary", true SET objUpload = NOTHING %> I can also write something to the response stream first and it works fine. <% Response.Write("server this") SET objUpload = server.createObject("Persits.Upload") objUpload.sendBinary "D:\sites\file.pdf", true, "application/octet-binary", true SET objUpload = NOTHING %> Does anyone have any ideas of what could be causing this or has anyone ran into a similar situation? I'm sure it has something to do with the setup in IIS 7.

  • How to extract a Vorbis stream from a WAVE file?

    - by H.B.
    I would like to move the Vorbis stream into an ogg container but ffmpeg does not seem to recognize the stream. Even though MPlayer gives this output upon playback: Opening audio decoder: [acm] Win32/ACM decoders Loading codec DLL: 'vorbis.acm' Loaded DLL driver vorbis.acm at 10000000 Warning! ACM codec reports srcsize=0 AUDIO: 44100 Hz, 2 ch, s16le, 128.0 kbit/9.07% (ratio: 16000-176400) Selected audio codec: [vorbisacm] afm: acm (OggVorbis ACM) ffmpeg: ffmpeg -i Source.wav -acodec copy Target.ogg Input #0, wav, from 'Source.wav': Duration: 00:02:15.17, bitrate: 128 kb/s Stream #0.0: Audio: qg[0][0] / 0x6771, 44100 Hz, 2 channels, 128 kb/s [ogg @ 00000000003096C0] Unsupported codec id in stream 0 Output #0, ogg, to 'Target.ogg': Metadata: encoder : Lavf53.6.0 Stream #0.0: Audio: qg[0][0] / 0x6771, 44100 Hz, 2 channels, 128 kb/s Stream mapping: Stream #0.0 -> #0.0 Could not write header for output file #0 (incorrect codec parameters ?) Of course this does not necessarily need to be done via ffmpeg, any method that is workable would be fine... I have cut down one of the files to 512KB: sample.wav (Changed two chunk size fields in the wave header to account for this, the embedded stream is cut "without notice")

  • -[NSCFData writeStreamHandleEvent:]: unrecognized selector sent to instance in a stream callback

    - by user295491
    Hi everyone, I am working with streams and sockets in iPhone SDK 3.1.3 the issue is when the program accept a callback and I want to handle this writestream callback the following error is triggered " Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: ' -[NSCFData writeStreamHandleEvent:]: unrecognized selector sent to instance 0x17bc70'" But I don't know how to solve it because everything seems fine. Even when I run the debugger there is no error the program works. Any hint here will help! The code of the callback is: void myWriteStreamCallBack (CFWriteStreamRef stream, CFStreamEventType eventType, void *info){ NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; Connection *handlerEv = [(Connection *)info retain] autorelease]; [handlerEv writeStreamHandleEvent:eventType]; [pool release]; } The code of the writeStreamHandleEvent: - (void)writeStreamHandleEvent:(CFStreamEventType) eventType{ switch(eventType) { case kCFStreamEventOpenCompleted: writeStreamOpen = YES; break; case kCFStreamEventCanAcceptBytes: NSLog(@"Writing in the stream"); [self writeOutgoingBufferToStream]; break; case kCFStreamEventErrorOccurred: error = CFWriteStreamGetError(writeStream); fprintf(stderr, "CFReadStreamGetError returned (%ld, %ld)\n", error.domain, error.error); CFWriteStreamUnscheduleFromRunLoop(writeStream, CFRunLoopGetCurrent(),kCFRunLoopCommonModes); CFWriteStreamClose(writeStream); CFRelease(writeStream); break; case kCFStreamEventEndEncountered: CFWriteStreamUnscheduleFromRunLoop(writeStream, CFRunLoopGetCurrent(),kCFRunLoopCommonModes); CFWriteStreamClose(writeStream); CFRelease(writeStream); break; } } The code of the stream configuration: CFSocketContext ctx = {0, self, nil, nil, nil}; CFWriteStreamSetClient (writeStream,registeredEvents, (CFWriteStreamClientCallBack)&myWriteStreamCallBack,(CFStreamClientContext *)(&ctx) ); CFWriteStreamScheduleWithRunLoop (writeStream, CFRunLoopGetCurrent(), kCFRunLoopDefaultMode); You can see that there is nothing strange!, well at least I don't see it. Thank you in advance.

  • Webcam video stream processing.

    - by vikramtheone
    Hi Guys, I'm working with an image processing project, my final goal is to detect features on a real time video and finally track those features. I will be working with an Embedded Processor Platform called Freescale's i.MX515, it is a 32-bit media processor running on Ubuntu 9.04. Right now I'm working on the algorithms to locate the features, so, I'm using still images. When I'm satisfied with the results I will have to start using a video stream and I don't want to make use of a video file as a source stream, because then I will have to worry about video decoders then. Instead I would like to plug in a USB Wecam to the embedded platform (It has USB ports on it), directly take the frames as they are captured and send it to my application. I will take care to buy a webcam which will be supported in Linux (Device driver). But my question is will I be able to capture the incoming video stream from the webcam and send it to my application? Will I be able to configure the webcam and DMA to write the incoming frames in a particular memory location whose pointer I can simply pass to my application? (Confused!!!) I hope I could convey my doubts, can anyone guide me with what steps that I have to take to achieve all of these easily? Do you foresee any impossibility here? Help!!! Regards Vikram

  • Stream PDF to another local App

    - by Nathan
    Hi, I'm currently trying to optimize a small firefox extension that will grab a pdf off the current document and send it to a port that another local application is listening on. Right now it uses a terrifying hackjob of cache viewer. The way I'm getting it is loading the cache, searching through it using the current URL and grabbing the file and saving it to a temp directory. Then I stream the file in, delete the temp, and send it through the socket. Now, my new design, ideally I'd want to build it from scratch and cut out saving it to the local machine at all, and just stream it through the socket. I've been looking at doing something like, //check page to ensure its a pdf //init in/out streams //stream through sock //flush Now, this would be vastly superior to the 400 line hacked up mess I have now, but I'm new to building FF extensions, and after reading a lot about URIs and the file streaming and such I'm probably more confused than when I started trying to fix this three hours ago. I'm okay with sending things through the sockets and whatnot, I understand that, I'm mainly confused about what multitude of interfaces I want to use. Gah! Thanks! Also, long time reader, first time poster!

  • App-Engine Parse a UrlFetch UTF-8 encoded stream

    - by Davidrd91
    I am trying to parse an XML from a URL using the xml.sax parser. I know there are other libraries to use but coming from Java this is the one I am most familiar with and seems the least complicated to me. The code I'm using to parse is as follows: parser = xml.sax.make_parser() handler = MangaHandler() parser.setContentHandler(handler) url = urlfetch.Fetch('http://www.mangapanda.com/alphabetical', allow_truncated = False, follow_redirects = False, deadline = False) xml.sax.parseString(url.content, handler) This returns a SaxException (invalid token) once the parser reaches the first & sign: SAXParseException: <unknown>:582:34: not well-formed (invalid token) Because urlfetch returns a string and not a stream I cannot use the parse() (which only works with streams) and am left to use parseString() instead. To see if parsing as a stream would fix this I tried: parser.parse(io.StringIO(url.content).encode('utf-8')) but this returns: TypeError: initial_value must be unicode or None, not str I have also tried to use the urllib2 libraries which do return a stream instead of urlfetch but the file is too large and is automatically truncated, leaving me with missing data. Any Sort of work-around for this would be greatly appreciated as I've spent days getting around one obstacle just to be stopped by another.

  • overloaded stream insertion operator with a vector

    hi, i'm trying to write an overloaded stream insertion operator for a class who's only member is a vector. i dont really know what i'm doing. (lets make that clear) it's a vector of "Points" which is a struct containing two doubles. i figure what i want is to insert user input (a bunch of doubles) into a stream that i then send to a modifier method? i keep working off other stream insertion examples such as... std::ostream& operator<< (std::ostream& o, Fred const& fred) { return o << fred.i_; } but when i try a similar..... istream & operator >> (istream &inStream, Polygon &vertStr) { inStream >> ws; inStream >> vertStr.vertices; return inStream; } i get an error "no match for operator etc etc. if i leave off the .vertices it compiles but i figure it's not right?

  • How to encrypt and save a binary stream after serialization and read it back?

    - by Anindya Chatterjee
    I am having some problems in using CryptoStream when I want to encrypt a binary stream after binary serialization and save it to a file. I am getting the following exception System.ArgumentException : Stream was not readable. Can anybody please show me how to encrypt a binary stream and save it to a file and deserialize it back correctly? The code is as follows: class Program { public static void Main(string[] args) { var b = new B {Name = "BB"}; WriteFile<B>(@"C:\test.bin", b, true); var bb = ReadFile<B>(@"C:\test.bin", true); Console.WriteLine(b.Name == bb.Name); Console.ReadLine(); } public static T ReadFile<T>(string file, bool decrypt) { T bObj = default(T); var _binaryFormatter = new BinaryFormatter(); Stream buffer = null; using (var stream = new FileStream(file, FileMode.OpenOrCreate)) { if(decrypt) { const string strEncrypt = "*#4$%^.++q~!cfr0(_!#$@$!&#&#*&@(7cy9rn8r265&$@&*E^184t44tq2cr9o3r6329"; byte[] dv = {0x12, 0x34, 0x56, 0x78, 0x90, 0xAB, 0xCD, 0xEF}; CryptoStream cs; DESCryptoServiceProvider des = null; var byKey = Encoding.UTF8.GetBytes(strEncrypt.Substring(0, 8)); using (des = new DESCryptoServiceProvider()) { cs = new CryptoStream(stream, des.CreateEncryptor(byKey, dv), CryptoStreamMode.Read); } buffer = cs; } else buffer = stream; try { bObj = (T) _binaryFormatter.Deserialize(buffer); } catch(SerializationException ex) { Console.WriteLine(ex.Message); } } return bObj; } public static void WriteFile<T>(string file, T bObj, bool encrypt) { var _binaryFormatter = new BinaryFormatter(); Stream buffer; using (var stream = new FileStream(file, FileMode.Create)) { try { if(encrypt) { const string strEncrypt = "*#4$%^.++q~!cfr0(_!#$@$!&#&#*&@(7cy9rn8r265&$@&*E^184t44tq2cr9o3r6329"; byte[] dv = {0x12, 0x34, 0x56, 0x78, 0x90, 0xAB, 0xCD, 0xEF}; CryptoStream cs; DESCryptoServiceProvider des = null; var byKey = Encoding.UTF8.GetBytes(strEncrypt.Substring(0, 8)); using (des = new DESCryptoServiceProvider()) { cs = new CryptoStream(stream, des.CreateEncryptor(byKey, dv), CryptoStreamMode.Write); buffer = cs; } } else buffer = stream; _binaryFormatter.Serialize(buffer, bObj); buffer.Flush(); } catch(SerializationException ex) { Console.WriteLine(ex.Message); } } } } [Serializable] public class B { public string Name {get; set;} } It throws the serialization exception as follows The input stream is not a valid binary format.

  • Getting access to a binary response byte-by-byte in classic asp/JScript

    - by user89691
    I asked this question a few days ago but it seems to have gone cold fairly quickly. What I want to do is pretty simple and I can't believe someone hasn't figured it out. Solution needs to be JScript classic ASP. I am reading a file from a remote server and I want to process that (binary) file on my server and spit the results back to the client as XML. Here's a simplified version of what I am trying to do. This code runs, or will if the URL is filled in for your site. This test file is readbin.asp. It reads a file called test.bin, and writes the result to a stream. I used a stream because that makes it easier to read the file and parse the contents. Basically I want to: while not end of stream read byte from stream process byte here is readbin.asp: <%@ LANGUAGE = JScript %> <% var url = "http:// (... your URL to the file test.bin goes here...) " ; var xmlhttp = Server.CreateObject ("MSXML2.ServerXMLHTTP") ; xmlhttp.open ("GET", url, false) ; xmlhttp.send () ; var BinaryInputStream = Server.CreateObject ("ADODB.Stream") ; BinaryInputStream.Type = 1 ; // binary BinaryInputStream.Open ; BinaryInputStream.Write (xmlhttp.responseBody) ; BinaryInputStream.Position = 0 ; Response.Write ("BinaryInputStream.size = " + BinaryInputStream.size + "<br>") ; Response.Write ("BinaryInputStream = " + BinaryInputStream + "<br>") ; var ByteValue = BinaryInputStream.read (1) ; Response.Write ("ByteValue = " + ByteValue + "<br>") ; Response.Write ("typeof (ByteValue) = " + typeof (ByteValue) + "<br>") ; %> My problem is: how do I get ByteValue as a number 0..255? typeof (ByteValue) is "unknown". Ord?? Byte()?? Asc?? Chr??

  • .NET: Problems creating email attachment from MemoryStream.

    - by David
    Hi all I'm using the following method to create an attachment from a MemoryStream: public void AddAttachment(Stream stream, string filename, string mimeType) { byte[] buffer = ((MemoryStream) stream).GetBuffer(); Attachment attachment = new Attachment(stream, filename, mimeType); _mail.Attachments.Add(attachment); } Note that the first line is not necessary isn't necessary for the attachment functionality, it's just useful to have the byte[] handy during debugging so that I can see how big it is. (It generally has around 80,000 elements.) The code runs fine and the email is sent. When Outlook receives the email, in the Inbox it displays the attachment symbol, but when you go into the email the attachment isn't there. Unfortunately I don't have access to the mail server to find out more about the email, e.g. what the attachment looks like, its size etc. Can anyone suggest what properties of the MemoryStream argument might tell me if it is in some way invalid for attachment? Or think of anything else I might try? Thank you. David

  • Combining the streams:Web application

    - by Surendra J
    This question deals mainly with streams in web application in .net. In my webapplication I will display as follows: bottle.doc sheet.xls presentation.ppt stackof.jpg Button I will keep checkbox for each one to select. Suppose a user selected the four files and clicked the button,which I kept under. Then I instantiate clasees for each type of file to convert into pdf, which I wrote already and converted them into pdf and return them. My problem is the clases is able to read the data form URL and convert them into pdf. But I don't know how to return the streams and merge them. string url = @"url"; //Prepare the web page we will be asking for HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); request.Method = "GET"; request.ContentType = "application/mspowerpoint"; request.UserAgent = "Mozilla/4.0+(compatible;+MSIE+5.01;+Windows+NT+5.0"; //Execute the request HttpWebResponse response = (HttpWebResponse)request.GetResponse(); //We will read data via the response stream Stream resStream = response.GetResponseStream(); //Write content into the MemoryStream BinaryReader resReader = new BinaryReader(resStream); MemoryStream PresentaionStream = new MemoryStream(resReader.ReadBytes((int)response.ContentLength)); //convert the presention stream into pdf and save it to local disk. But I would like to return the stream again. How can I achieve this any Ideas are welcome.

Is there a way to make .readline non-bloking or to check if there is data on the stream before I invoke .readline? I'd like this to be portable or at least work under Windows and Linux. here is how I do it for now (It's blocking on the .readline if no data is avaible): p = subprocess.Popen('myprogram.exe', stdout = subprocess.PIPE) str = p.stdout.readline() Thanks for your help.

If I try to manually hit the Facebook access_token URL that my code is attempting to fetch, I get an actual payload returned in the browser: access_token=XYZ&expires=6508 (where XYZ is the access token) So for some reason, there is a problem with the access_token URL specifically when used with file_get_contents(). At first, I thought it was a security issue with my webhoster, but I have verified with phpinfo() that allow url open is indeed allowed. I have also tried this code and verified it works: $foo = file_get_contents('http://google.com'); echo $foo Anyone have any ideas why file_get_contents() is failing with the Facebook access_token URL?
