  • C++ overloading comparative operators for a MyString class

    - by Taylor Gang
    bool operator == (const MyString& left, const MyString& right) { if(left.value == right.value) return true; else return false; } bool operator != (const MyString& left, const MyString& right) { if(left == right) return false; else return true; } bool operator < (const MyString& left, const MyString& right) { if(strcmp(left.value, right.value) == -1) return true; else return false; } bool operator > (const MyString& left, const MyString& right) { if(strcmp(left.value, right.value) == 1) return true; else return false; } bool operator <= (const MyString& left, const MyString& right) { if(strcmp(left.value, right.value) == -1 || strcmp(left.value, right.value) == 0) return true; else return false; } bool operator >= (const MyString& left, const MyString& right) { if(strcmp(left.value, right.value) == 1 || strcmp(left.value, right.value) == 0) return true; else return false; } So these are my implemented comparison operators for my MyString class, they fail the test program that my professor gave me and could use some direction. Thanks in advance for any and all help I receive.

  • Lazy evaluation with ostream C++ operators

    - by SavinG
    I am looking for a portable way to implement lazy evaluation in C++ for logging class. Let's say that I have a simple logging function like void syslog(int priority, const char *format, ...); then in syslog() function we can do: if (priority < current_priority) return; so we never actually call the formatting function (sprintf). On the other hand, if we use logging stream like log << LOG_NOTICE << "test " << 123; all the formating is always executed, which may take a lot of time. Is there any possibility to actually use all the goodies of ostream (like custom << operator for classes, type safety, elegant syntax...) in a way that the formating is executed AFTER the logging level is checked ?

  • C# Extend array type to overload operators

    - by Episodex
    I'd like to create my own class extending array of ints. Is that possible? What I need is array of ints that can be added by "+" operator to another array (each element added to each), and compared by "==", so it could (hopefully) be used as a key in dictionary. The thing is I don't want to implement whole IList interface to my new class, but only add those two operators to existing array class. I'm trying to do something like this: class MyArray : Array<int> But it's not working that way obviously ;). Sorry if I'm unclear but I'm searching solution for hours now... UPDATE: I tried something like this: class Zmienne : IEquatable<Zmienne> { public int[] x; public Zmienne(int ilosc) { x = new int[ilosc]; } public override bool Equals(object obj) { if (obj == null || GetType() != obj.GetType()) { return false; } return base.Equals((Zmienne)obj); } public bool Equals(Zmienne drugie) { if (x.Length != drugie.x.Length) return false; else { for (int i = 0; i < x.Length; i++) { if (x[i] != drugie.x[i]) return false; } } return true; } public override int GetHashCode() { int hash = x[0].GetHashCode(); for (int i = 1; i < x.Length; i++) hash = hash ^ x[i].GetHashCode(); return hash; } } Then use it like this: Zmienne tab1 = new Zmienne(2); Zmienne tab2 = new Zmienne(2); tab1.x[0] = 1; tab1.x[1] = 1; tab2.x[0] = 1; tab2.x[1] = 1; if (tab1 == tab2) Console.WriteLine("Works!"); And no effect. I'm not good with interfaces and overriding methods unfortunately :(. As for reason I'm trying to do it. I have some equations like: x1 + x2 = 0.45 x1 + x4 = 0.2 x2 + x4 = 0.11 There are a lot more of them, and I need to for example add first equation to second and search all others to find out if there is any that matches the combination of x'es resulting in that adding. Maybe I'm going in totally wrong direction?

  • asp.net mvc compress stream and remove whitespace

    - by Bigfellahull
    Hi, So I am compressing my output stream via an action filter: var response = filterContext.HttpContext.Response; response.Filter = new DeflateStream(response.Filter), CompressionMode.Compress); Which works great. Now, I would also like to remove the excess whitespace present. I found Mads Kristensen's http module http://madskristensen.net/post/A-whitespace-removal-HTTP-module-for-ASPNET-20.aspx. I added the WhitespaceFilter class and added a new filter like the compression: var response = filterContext.HttpContext.Response; response.Filter = new WhitepaperFilter(response.Filter); This also works great. However, I seem to be having problems combining the two! I tried: var response = filterContext.HttpContext.Response; response.Filter = new DeflateStream(new WhitespaceFilter(response.Filter), CompressionMode.Compress); However this results in some major issues. The html gets completely messed up and sometimes I get an 330 error. It seems that the Whitespace filter write method gets called multiple times. The first time the html string is fine, but on subsequent calls its just random characters. I thought it might be because the stream had been deflated, but isnt the whitespace filter using the untouched stream and then passing the resulting stream to the DeflateStream call? Any ideas?

  • Stream Reuse in C#

    - by MikeD
    I've been playing around with what I thought was a simple idea. I want to be able to read in a file from somewhere (website, filesystem, ftp), perform some operations on it (compress, encrypt, etc.) and then save it somewhere (somewhere may be a filesystem, ftp, or whatever). It's a basic pipeline design. What I would like to do is to read in the file and put it onto a MemoryStream, then perform the operations on the data in the MemoryStream, and then save that data in the MemoryStream somewhere. I was thinking I could use the same Stream to do this but run into a couple of problems: Everytime I use a StreamWriter or StreamReader I need to close it and that closes the stream so that I cannot use it anymore. That seems like there must be some way to get around that. Some of these files may be big and so I may run out of memory if I try to read the whole thing in at once. I was hoping to be able to spin up each of the steps as separate threads and have the compression step begin as soon as there is data on the stream, and then as soon as the compression has some compressed data available on the stream I could start saving it (for example). Is anything like this easily possible with the C# Streams? ANyone have thoughts as to how to accomplish this best? Thanks, Mike

  • XMLStreamReader and a real stream

    - by Yuri Ushakov
    Update There is no ready XML parser in Java community which can do NIO and XML parsing. This is the closest I found, and it's incomplete: http://wiki.fasterxml.com/AaltoHome I have the following code: InputStream input = ...; XMLInputFactory xmlInputFactory = XMLInputFactory.newInstance(); XMLStreamReader streamReader = xmlInputFactory.createXMLStreamReader(input, "UTF-8"); Question is, why does the method #createXMLStreamReader() expects to have an entire XML document in the input stream? Why is it called a "stream reader", if it can't seem to process a portion of XML data? For example, if I feed: <root> <child> to it, it would tell me I'm missing the closing tags. Even before I begin iterating the stream reader itself. I suspect that I just don't know how to use a XMLStreamReader properly. I should be able to supply it with data by pieces, right? I need it because I'm processing a XML stream coming in from network socket, and don't want to load the whole source text into memory. Thank you for help, Yuri.

  • deserializing multiple types from a stream

    - by clanier9
    I have a card game program, and so far, the chat works great back and forth over the TCPClient streams between host and client. I want to make it do this with serializing and deserializing so that I can also pass cards between host and client. I tried to create a separate TCPClient stream for the passing of cards but it didn't work and figured it may be easier to keep one TCPClient stream that gets the text messages as well as cards. So I created a class, called cereal, which has the properties for the cards that will help me rebuild the card from an embedded database of cards on the other end. Is there a way to make my program figure out whether a card has been put in the stream or if it's just text in the stream so I can properly deserialize it to a string or to a cereal? Or should I add a string property to my cereal class and when that property is filled in after deserializing to the cereal, i'll know it's just text (if that field is empty after deserializing i'll know it's a card)? I'm thinking a try catch, where it tries to deserialize to a string, and if it fails it will catch and cast as a cereal. Or am I just way off base with this and should choose another route? I'm using visual studio 2011, am using a binaryformatter, and am new to serializing/deserializing.

  • 48-bit bitwise operations in Javascript?

    - by randomhelp
    I've been given the task of porting Java's Java.util.Random() to JavaScript, and I've run across a huge performance hit/inaccuracy using bitwise operators in Javascript on sufficiently large numbers. Some cursory research states that "bitwise operators in JavaScript are inherently slow," because internally it appears that JavaScript will cast all of its double values into signed 32-bit integers to do the bitwise operations (see https://developer.mozilla.org/En/Core_JavaScript_1.5_Reference/Operators/Bitwise_Operators for more on this.) Because of this, I can't do a direct port of the Java random number generator, and I need to get the same numeric results as Java.util.Random(). Writing something like this.next = function(bits) { if (!bits) { bits = 48; } this.seed = (this.seed * 25214903917 + 11) & ((1 << 48) - 1); return this.seed >>> (48 - bits); }; (which is an almost-direct port of the Java.util.Random()) code won't work properly, since Javascript can't do bitwise operations on an integer that size.) I've figured out that I can just make a seedable random number generator in 32-bit space using the Lehmer algorithm, but the trick is that I need to get the same values as I would with Java.util.Random(). What should I do to make a faster, functional port?

  • Setting Up a Virtual Sound Device To Stream Output via TCP/IP

    - by Martindale
    I'm interested in installing a custom driver / device that will open a socket (or listen) and stream audio via TCP/IP in both Windows and Linux. I would like to be able to specify this device as my "Output" for specific applications so that I can route my audio through a completely unique machine (for example, in complex Synergy setups where my headphones might be connected to one machine, but audio is being generated by another.) In Linux, I expect this to be very easy, but I anticipate having to install a custom driver in Windows.

  • Add keyframes to a stream (FLV from RTMP)

    - by acidzombie24
    I downloaded a RTMP stream to my desktop. It uses the FLV (Flash) video codec. I do not want to reprocess/transcode/whatever to this video. VirtualDub can delete sections of video and since it's not encoding again the quality is the same and the filesize shrinks. I want to do something similar but instead add keyframes and not encode. What can I use?

  • Checking rtp stream audio quality.

    - by chills42
    We are working in a test environment and need to monitor the audio quality of an rtp stream that is being captured using tshark. Right now we are able to capture the audio and access the file through wireshark, but we would like to find a way to save the audio to a .wav file (or similar) via the command line. Does anyone know of a tool that can do this?

    Hi. I have an old box that I'd like to use as a private sever to stream movies off of. My upload speed is about 0.5/Mb/s, so I need something that compresses well. I'd like to be able to access these movies from anywhere, through the web, through some interface (maybe the divx web player? flash player? some other protocol?) Can anyone recommend anything good? (Using Windows XP) Thanks!

  • Purpose of overloading operators in C++?

    - by Geo Drawkcab
    What is the main purpose of overloading operators in C++? In the code below, << and >> are overloaded; what is the advantage to doing so? #include <iostream> #include <string> using namespace std; class book { string name,gvari; double cost; int year; public: book(){}; book(string a, string b, double c, int d) { a=name;b=gvari;c=cost;d=year; } ~book() {} double setprice(double a) { return a=cost; } friend ostream& operator <<(ostream& , book&); void printbook(){ cout<<"wignis saxeli "<<name<<endl; cout<<"wignis avtori "<<gvari<<endl; cout<<"girebuleba "<<cost<<endl; cout<<"weli "<<year<<endl; } }; ostream& operator <<(ostream& out, book& a){ out<<"wignis saxeli "<<a.name<<endl; out<<"wignis avtori "<<a.gvari<<endl; out<<"girebuleba "<<a.cost<<endl; out<<"weli "<<a.year<<endl; return out; } class library_card : public book { string nomeri; int raod; public: library_card(){}; library_card( string a, int b){a=nomeri;b=raod;} ~library_card() {}; void printcard(){ cout<<"katalogis nomeri "<<nomeri<<endl; cout<<"gacemis raodenoba "<<raod<<endl; } friend ostream& operator <<(ostream& , library_card&); }; ostream& operator <<(ostream& out, library_card& b) { out<<"katalogis nomeri "<<b.nomeri<<endl; out<<"gacemis raodenoba "<<b.raod<<endl; return out; } int main() { book A("robizon kruno","giorgi",15,1992); library_card B("910CPP",123); A.printbook(); B.printbook(); A.setprice(15); B.printbook(); system("pause"); return 0; }

  • Is it possible to play multiple audio streams from one "jukebox" to multiple Airport Express devices?

    - by Alex Reynolds
    I have set up a Mac mini as a jukebox that streams audio to an Airport Express in another room in the house, using the AirPlay/AirTunes feature in iTunes. I control this with the iOS Remote app, and this works great. At the present time, it looks like the Mac mini's copy of iTunes gets taken over by the Remote app, while streaming. If I set up a second Airport Express in room B, is there a way to set it up (as well as the jukebox) so that it can receive and play its own unique music stream ("stream B"), separate from what's going on at the Mac mini, or in room A, which is playing stream A? To accomplish this, I would be happy to buy a copy of Rogue Amoeba's AirFoil if it will allow sending multiple, separate audio streams from one computer to the multiple wireless bridges, while using the Remote app (or a Rogue Amoeba equivalent for iOS). However, it is unclear to me from their site documentation, whether that is possible or not. I'd prefer to give the points to an answer that solves this problem. If you don't know if it can be done, or do not think it can be done, please allow others to answer. I appreciate your help. Thanks for your advice.

  • WPD MTP data stream hanging on Release

    - by Jonathan Potter
    I've come across a weird problem when reading data from a MTP-compatible mobile device using the WPD (Windows Portable Devices) API, under Windows 8 (not tried any other Windows versions yet). The symptom is, when calling Release on an IStream interface obtained via the IPortableDeviceResources::GetStream function, occasionally the Release call will hang and not return until the device is disconnected from the PC. After some experimentation I've discovered that this never happens as long as the entire contents of the stream have been read. But if the stream has only been partially read (say, the first 256Kb of the file), it can happen seemingly at random (although quite frequently). This has been reproduced with an iPhone and a Windows Phone 8 mobile, so it does not seem to be device-specific. Has anyone come across this sort of issue before? And more importantly, does anyone know of a way to solve it other than by always reading the entire contents of the stream? Thanks!

  • Use a "x-dom-event-stream" stream in javascript ?

    - by rnaud
    Hello, HTML5 draft contains an API called EventSource to stream data (notifications) trough javascript using only one server call. Looking it up, I found an exemple on Opera Labs of the javascript part : document.getElementsByTagName("event-source")[0] .addEventListener("server-time", eventHandler, false); function eventHandler(event) { // Alert time sent by the server alert(event.data); } and the server side part : <?php header("Content-Type: application/x-dom-event-stream"); while(true) { echo "Event: server-time\n"; $time = time(); echo "data: $time\n"; echo "\n"; flush(); sleep(3); } ?> But as of today, it seems only Opera has implemented the API, neither Chrome nor Safari have a working version (Am I wrong here ?) So my question is, is there any other way in javascript, maybe more complex, to use this one stream to get data ?

  • Best practices retrieving XML/stream from HTTP in Android

    - by Jeffrey
    Hello everyone, what are the best practices parsing XML from an HTTP resource in Android? I've been using HttpURLConnection to retrieve an InputStream, wrapping it with a BufferedInputStream, and then using SAX to parse the buffered stream. For the most part it works, though I do receive error reports of SocketTimeoutException: The operation timed out or general parsing error. I believe it's due to the InputStream. Would using HttpClient instead of HttpURLConnection help? If yes, why? Should the stream be output to a file, having the file parsed instead of the stream? Any input or direction would be greatly appreciated. Thanks for your time.

  • Writing asynchronously on a stream in cocoa

    - by Richard Ibarra
    Hi folks I have been trying to find any way for writing asynchronously on a stream in Cocoa. I have a set of events in my applications which will try to send data through the socket but i can't be blocked during this transmission due to design terms. I have tried setting a delegate on the output stream and check the event NSStreamEventHasSpaceAvailable but I don't know how this can be combined with the events that put data into the stream. Is there anyway for doing that? I thought using NSThread but I guess there is a better option. Cheers

  • WPF: Convert memory stream to BitmapImage?

    - by David Veeneman
    I have an image that was originally a PNG that I have converted to a byte[] and saved in a database. Originally, I simply read the PNG into a memory stream and converted the stream into a byte[]. Now I want to read the byte[] back and convert it to a BitmapImage, so that I can bind a WPF Image control to it. I am seeing a lot of contradictory and confusing code online to accomplish the task of converting a byte[] to a BitmapImage. I am not sure whether I need to add any code due to the fact that the image was originally a PNG. Can anyone provide the code to convert the stream to a BitmapImage? Thanks for your help.
