  • Saving a reference to a int.

    - by Scott Chamberlain
    Here is a much simplified version of what I am trying to do static void Main(string[] args) { int test = 0; int test2 = 0; Test A = new Test(ref test); Test B = new Test(ref test); Test C = new Test(ref test2); A.write(); //Writes 1 should write 1 B.write(); //Writes 1 should write 2 C.write(); //Writes 1 should write 1 Console.ReadLine(); } class Test { int _a; public Test(ref int a) { _a = a; //I loose the reference here } public void write() { var b = System.Threading.Interlocked.Increment(ref _a); Console.WriteLine(b); } } In my real code I have a int that will be incremented by many threads however where the threads a called it will not be easy to pass it the parameter that points it at the int(In the real code this is happening inside a IEnumerator). So a requirement is the reference must be made in the constructor. Also not all threads will be pointing at the same single base int so I can not use a global static int either. I know I can just box the int inside a class and pass the class around but I wanted to know if that is the correct way of doing something like this? What I think could be the correct way: static void Main(string[] args) { Holder holder = new Holder(0); Holder holder2 = new Holder(0); Test A = new Test(holder); Test B = new Test(holder); Test C = new Test(holder2); A.write(); //Writes 1 should write 1 B.write(); //Writes 2 should write 2 C.write(); //Writes 1 should write 1 Console.ReadLine(); } class Holder { public Holder(int i) { num = i; } public int num; } class Test { Holder _holder; public Test(Holder holder) { _holder = holder; } public void write() { var b = System.Threading.Interlocked.Increment(ref _holder.num); Console.WriteLine(b); } } Is there a better way than this?

  • PHP: variable-length argument list by reference?

    - by GetFree
    Is it possible to create a PHP function that takes a variable number of parameters all of them by reference? It doesn't help me a function that receives by reference an array of values nor a function that takes its arguments wrapped in an object because I'm working on function composition and argument binding. Don't think about call-time pass-by-reference either. That thing shouldn't even exist.

  • Restoring and passing data to an already running instance of a .NET application

    - by mtranda
    The goal is to have an application that runs in the system tray and can either accept user input from its actual GUI (which isn't the actual issue) OR accept command line parameters (that would actually be done via a context menu in windows explorer). Now, while I'm aware that the command line parameters are not exactly possible once the application has started, I need a way to pass data to the already running application instance via some form of handler. I'm thinking maybe define and raise some sort of event? Thanks in advance.

  • typeid() returns extra characters in g++

    - by Appu
    class foo { public: void say_type_name() { std::cout << typeid(this).name() << std::endl; } }; int main() { foo f;; f.say_type_name(); } Above code prints P3foo on my ubuntu machine with g++. I am not getting why it is printing P3foo instead of just foo. If I change the code like std::cout << typeid(*this).name() << std::endl; it prints 3foo. Any thoughts?

  • Objects in Java ArrayList don't get updated.

    - by Sbm007
    This is going to be a very long post, hopefully you can understand what I'm talking about and I appreciate any help. Thanks Basically, I've created a personal, non-commercial project (which I don't plan to release) that can read ZIP and RAR files. It can only read the contents in the archive, the folders inside, the files inside the folders and its properties (such as last modified date, last modified time, CRC checksum, uncompressed size, compressed size and file name). It can't extract files either, so it's really a ZIP/RAR viewer if you may. Anyway that's slightly irrelevant to my problem but I thought I'd give you some background info. Now for my problem: I can successfully list all the folders and files inside a ZIP archive, so now I want to take that raw input and link it together in some useful way. I made 2 classes: ArchiveFile (represents a file inside a ZIP) and ArchiveFolder (represents a folder inside a ZIP). They both have some useful methods such as getLastModifiedDate, getName, getPath and so on. But the difference is that ArchiveFolder can hold an ArrayList of ArchiveFile's and additional ArchiveFolder's (think of this as files and folders inside a folder). Now I want to populate my raw input into one root ArchiveFolder, which will have all the files in the root dir of the ZIP in the ArchiveFile's ArrayList and any additional folders in the root dir of the ZIP in the ArchiveFolder's ArrayList (and this process can continue on like this like a chain reaction (more files/folders in that ArchiveFolder etc etc). So I came up with the following code: while (archive.hasMore()) { String path = ""; ArchiveFolder current = root; String[] contents = archive.getName().split("/"); for (int x = 0; x < contents.length; ++x) { if (x == (contents.length - 1) && !archive.getName().endsWith("/")) { // If on last item and item is a file path += contents[x]; // Update final path ArchiveFile file = new ArchiveFile(path, contents[x], archive.getUncompressedSize(), archive.getCompressedSize(), archive.getModifiedTime(), archive.getModifiedDate(), archive.getCRC()); current.addFile(file); // Create and add the file to the current ArchiveFolder } else if (x == (contents.length - 1)) { // Else if we are on last item and it is a folder path += contents[x] + "/"; // Update final path ArchiveFolder folder = new ArchiveFolder(path, contents[x], archive.getModifiedTime(), archive.getModifiedDate()); current.addFolder(folder); // Create and add this folder to the current ArchiveFile } else { // Else if we are still traversing through the path path += contents[x] + "/"; // Update path ArchiveFolder folder = new ArchiveFolder(path, contents[x]); current.addFolder(folder); // Create and add folder (remember we do not know the modified date/time as all we know is the path, so we can deduce the name only) current = folder; // Update current ArchiveFolder to the newly created one for the next iteration of the for loop } } archive.getNext(); } Assume that root is the root ArchiveFolder (initially empty). And that archive.getName() returns the name of the current file OR folder in the following fashion: file.txt or folder1/file2.txt or folder4/folder2/ (this is a empty folder) etc. So basically the relative path from the root of the ZIP archive. Please read through the comments in the above code to familiarize yourself with it. Also assume that the addFolder method in an ArchiveFile, only adds the folder if it doesn't exist already (so there are no multiple folders) and it also updates the time and date of an existing folder if it is blank (ie it was a intermediate folder we only knew the name of, but now we know its details). The code for addFolder is (pretty self-explanitory): public void addFolder(ArchiveFolder folder) { int loc = folders.indexOf(folder); // folders is the ArrayList containing ArchiveFolder's if (loc == -1) { folders.add(folder); } else { ArchiveFolder real = folders.get(loc); if (real.time == null) { real.setTime(folder.getTime()); real.setDate(folder.getDate()); } } } So I can't see anything wrong with the code, it works and after finishing, the root ArchiveFolder contains all the files in the root of the ZIP as I want it to, and it contains all the direcories in the root folder as I want it to. So you'd think it works as expected, but no the ArchiveFolder's in the root folder don't contain the data inside those 'child' folders, it's just a blank folder with no additional files and folders (while it does really contain some more files/folders when viewed in WinZip). After debugging using Eclipse, the for loop does iterate through all the files (even those not included above), so this led me to believe that there is a problem with this line of the code: current = folder; What it does is, it updates the current folder (used as an intermediate by the loop) to the newly added folder. I thought Java passed by reference and thus all new operations and new additions in future ArchiveFile's and ArchiveFolder's are automatically updated, and parent ArchiveFolder's will be updated accordingly. But that does not appear to be the case? I know this is a long ass post and I really hope anyone can help me out with this. Thanks in advance.

  • Assign RegEx submatches to variables or map (C++/C)

    - by Michael
    I need to extract the SAME type of information (e.g. First name, Last Name, Telephone, ...), from numerous different text sources (each with a different format & different order of the variables of interest). I want a function that does the extraction based on a regular expression and returns the result as DESCRIPTIVE variables. In other words, instead of returning each match result as submatch[0], submatch[1], submatch[2], ..., have it do EITHER of the following: 1.) return std::map so that the submatches can be accessed via: submatch["first_name"], submatch["last_name"], submatch["telephone"] 2.) return a variables with the submatches so that the submatches can be accessed via: submatch_first_name, submatch_last_name, submatch_telephone I can write a wrapper class around boost::regex to do #1, but I was hoping there would be a built-in or a more elegant way to do this in C++/Boost/STL/C.

Is there any other ways I can design a quiz like this but without having to write a block of code for each radio button?

  • Get contact name from just the number

    - by user1190019
    Say i have an edit text and a button. In the edit text you would type a number and then when you hit the button it will either show the contact information or return with the name of that contact. I have tried all sorts of methods provided with no luck. The one i have successfully gotten the furthest with was the following... But i had no luck returning the name. Cursor phoneCursor = null; contactList = new HashMap<String,String>(); try{ Uri uContactsUri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI; String strProjection = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME; phoneCursor = getContentResolver().query(uContactsUri, null, null, null, strProjection); phoneCursor.moveToFirst(); String name = ""; String phoneNumber = ""; int nameColumn = phoneCursor.getColumnIndex(Phone.DISPLAY_NAME); int phoneColumn = phoneCursor.getColumnIndex(Phone.NUMBER); phoneCursor.moveToNext(); } } catch(Exception e){ Log.e("[SmsMain] getContactData", e.toString()); } finally{ if(phoneCursor != null){ phoneCursor.close(); phoneCursor = null; } } }

  • Docbook+Ant: Could not find variable with the name of fop.extensions

    - by rfkrocktk
    After a lot of spent time trying to get my article to compile in Ant with Docbook, I can't seem to make FO compilation work. I'm using Xalan 2.7.0, and everything else (both single-page and chunked HTML) compiles perfectly. It's only when I try to compile to FO that I get this error: Fatal Error! org.apache.xml.utils.WrappedRuntimeException: Could not find variable with the name of fop.extensions Cause: org.apache.xml.utils.WrappedRuntimeException: Could not find variable with the name of fop.extensions This is pretty strange and I can't seem to resolve it. I even added a <param> value defining the variable it "can't find:" <xslt style="docbook-xsl/fo/fo.xsl" in="documents/book.xml" out="output.fo"> <classpath> <fileset dir="lib" includes="**/*"/> </classpath> <param name="fop.extensions" expression="1"/> </xslt> Is there anything I can do to resolve this issue? It's really weird if you ask me. (Again, using the same code as above, all of my other Docbook compilation works just fine)

  • SoundManager / Jquery / Regular expression : Parse class name before certain character To Get SoundI

    - by j-man86
    So I am trying to access a jquery soundmanager variable from one script (wpaudio.js – from the wp-audio plugin) inside of another (init.js – my own javascript). I am creating an alternate pause/play button higher up on the page and need to resume the current soundID, which is contained as part of a class name in the DOM. Here is the code that creates that class name in wpaudio.js: function wpaButtonCheck() { if (!this.playState || this.paused) jQuery('#' + this.sID + '_play').attr('src', wpa_url + '/wpa_play.png'); else jQuery('#' + this.sID + '_play').attr('src', wpa_url + '/wpa_pause.png'); } Here is the output: where wpa0 would be the sID of the sound I need. My current script in init.js is: $('.mixesSidebar #currentSong .playBtn').toggle(function() { soundManager.pauseAll(); $(this).addClass('paused'); }, function() { soundManager.resumeAll(); $(this).removeClass('paused'); }); I need to change resumeAll to "resume(this.sID)", but I need to somehow store the sID onclick and call it in the above function. Alternately, I think a regular expression that could get the class name of the current play button and either parse the string up to the "_play" or use a trim function to get rid of "_play"– but I'm not sure how to do this. Thanks for your help!

  • iPhone: Accessing Composite Name in AddressBook Causes EXC_BAD_ACCESS

    - by Fyrian
    Hi everyone. I'm new to iPhone development and have a question I hope someone can help me with. I have a programmer working on an iPhone app for me and when I run the app in the simulator, it works great. But when I try to run it on my actual iPhone, I get a EXC_BAD_ACCESS error and the app locks up. Looking at the debugger, it's referencing the following code in my MainController as the problem: -(void)loadAddressBook{ NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; addressBookLoaded=1; [AddressbookRecord readAllContactTable:[self getDBPath]]; ABAddressBookRef addressBook = ABAddressBookCreate(); for(NSUInteger i=1;i<=ABAddressBookGetPersonCount(addressBook);i++) { ABRecordRef myPerson =ABAddressBookGetPersonWithRecordID (addressBook,(ABRecordID)(i)); NSString *name = (NSString*)ABRecordCopyCompositeName(myPerson); //save in database AddressbookRecord *addObj = [[AddressbookRecord alloc] initWithPrimaryKey:0]; addObj.ClientName=name; [addObj addNewContactEntry]; } addressBookLoaded=2; [pool release]; } More specifically, it points to this specific line as the problem: NSString *name =(NSString*)ABRecordCopyCompositeName(myPerson); My programmer can't seem to figure out what the problem is since he can't replicate it on his end. Does anyone have any ideas what would cause this problem??? Thanks!

  • Directly call distutils' or setuptools' setup() function with command name/options, without parsing

    - by Ryan B. Lynch
    I'd like to call Python's distutils' or setuptools' setup() function in a slightly unconventional way, but I'm not sure whether distutils is meant for this kind of usage. As an example, let's say I currently have a 'setup.py' file, which looks like this (lifted verbatim from the distutils docs--the setuptools usage is almost identical): from distutils.core import setup setup(name='Distutils', version='1.0', description='Python Distribution Utilities', author='Greg Ward', author_email='[email protected]', url='http://www.python.org/sigs/distutils-sig/', packages=['distutils', 'distutils.command'], ) Normally, to build just the .spec file for an RPM of this module, I could run python setup.py bdist_rpm --spec-only, which parses the command line and calls the 'bdist_rpm' code to handle the RPM-specific stuff. The .spec file ends up in './dist'. How can I change my setup() invocation so that it runs the 'bdist_rpm' command with the '--spec-only' option, WITHOUT parsing command-line parameters? Can I pass the command name and options as parameters to setup()? Or can I manually construct a command line, and pass that as a parameter, instead? NOTE: I already know that I could call the script in a separate process, with an actual command line, using os.system() or the subprocess module or something similar. I'm trying to avoid using any kind of external command invocations. I'm looking specifically for a solution that runs setup() in the current interpreter. For background, I'm converting some release-management shell scripts into a single Python program. One of the tasks is running 'setup.py' to generate a .spec file for further pre-release testing. Running 'setup.py' as an external command, with its own command line options, seems like an awkward method, and it complicates the rest of the program. I feel like there may be a more Pythonic way.

  • HDFS some datanodes of cluster are suddenly disconnected while reducers are running

    - by user1429825
    I have 8 slave computers and 1 master computer for running Hadoop (ver 0.21) some datanodes of cluster are suddenly disconnected while I was running MapReduce code on 10GB data After all mappers finished and around 80% of reducers was processed, randomly one or more datanode disconned from network. and then the other datanodes start to disappear from network even if I killed the MapReduce job when I found some datanode was disconnected.

  • php multidimensional array as name value pair

    - by Ayad Mfs
    For ecommerce, that expected name value pair I have the following approved code: function create_example_purchase() { set_credentials(); $purchase = array( 'name' => 'Digital Good Purchase Example', 'description' => 'Example Digital Good Purchase', 'amount' => '12.00', // sum of all item_amount 'items' => array( array( // First item 'item_name' => 'First item name', 'item_description' => 'a description of the 1st item', 'item_amount' => '6.00', 'item_tax' => '0.00', 'item_quantity' => 1, 'item_number' => 'XF100', ), array( // Second item 'item_name' => 'Second Item', 'item_description' => 'a description of the 2nd item', 'item_amount' => '3.00', 'item_tax' => '0.00', 'item_quantity' => 2, 'item_number' => 'XJ100', ), ) ); return new Purchase( $purchase); } I would like to get $items Array inside associative $purchase array dynamically from shipping cart. Is there a way to generate exactly the same output above? My dirty solution, to write $purchase array as string inclusive the generated $items array in a file and include it later in the called script. Help appreciated.

  • Windows batch - loop over folder string and parse out last folder name

    - by Tim Peel
    Hi, I need to grab the folder name of a currently executing batch file. I have been trying to loop over the current directory using the following syntax (which is wrong at present): set mydir = %~p0 for /F "delims=\" %i IN (%mydir%) DO @echo %i Couple of issues in that I cannot seem to pass the 'mydir' variable value in as the search string. It only seems to work if I pass in commands; I have the syntax wrong and cannot work out why. My thinking was to loop over the folder string with a '\' delimiter but this is causing problems too. If I set a variable on each loop then the last value set will be the current folder name. For example, given the following path: C:\Folder1\Folder2\Folder3\Archive.bat I would expect to parse out the value 'Folder3'. I need to parse that value out as its name will be part of another folder I am going to create further down in the batch file. Many thanks if anyone can help. I may be barking up the wrong tree completely so any other approaches would be greatly received also. Tim

  • Using StructureMap to create classes by a name?

    - by Bevan
    How can I use StructureMap to resolve to an appropriate implementation of an interface based on a name stored in an attribute? In my project, I have many different kinds of widgets, each descending from IWidget, and each decorated with an attribute specifying the kind of associated element. To illustrate: [Configuration("header")] public class HeaderWidget : IWidget { } [Configuration("linegraph")] public class LineGraphWidget : IWidget { } When processing my (XML) configuration file, I want to obtain an instance of the appropriate concrete class based on the name of the element I'm processing. public IWidget CreateWidget(XElement definition) { var kind = definition.Name.LocalName; var widget = // What goes here? widget.Configure(definition); return widget; } Each definition should result in a different widget being created - I don't need or want the instances to be shared. In the past I've written plenty of code to do this kind of thing manually, including writing a custom "roll-your-own" IoC container for one project. However, one of my goals with this project is to become proficient with StructureMap instead of reinventing the wheel. I think I've already managed to set up automatic scanning of assemblies so that StructureMap knows about all my IWidget implementations: public class WidgetRegistration : Registry { public WidgetRegistration() { Scan( scanner => { scanner.AssembliesFromApplicationBaseDirectory(); scanner.AddAllTypesOf<IWidget>(); }); } } However, this isn't registering the names of my widgets with StructureMap. What do I need to add to make my scenario work? (While I am trying to use StructureMap in this project, an answer showing me how to solve this problem with a different DI/IoC tool would still be valuable.)

  • Xerces C++ SAX Parsing Problem: expected class-name before '{' token

    - by aduric
    I'm trying to run through an example given for the C++ Xerces XML library implementation. I've copied the code exactly, but I'm having trouble compiling it. error: expected class-name before '{' token I've looked around for a solution, and I know that this error can be caused by circular includes or not defining a class before it is used, but as you can see from the code, I only have 2 files: MySAXHandler.hpp and MySAXHandler.cpp. However, the MySAXHandler class is derived from HandlerBase, which is included. MyHandler.hpp #include <xercesc/sax/HandlerBase.hpp> class MySAXHandler : public HandlerBase { public: void startElement(const XMLCh* const, AttributeList&); void fatalError(const SAXParseException&); }; MySAXHandler.cpp #include "MySAXHandler.hpp" #include <iostream> using namespace std; MySAXHandler::MySAXHandler() { } void MySAXHandler::startElement(const XMLCh* const name, AttributeList& attributes) { char* message = XMLString::transcode(name); cout << "I saw element: "<< message << endl; XMLString::release(&message); } void MySAXHandler::fatalError(const SAXParseException& exception) { char* message = XMLString::transcode(exception.getMessage()); cout << "Fatal Error: " << message << " at line: " << exception.getLineNumber() << endl; XMLString::release(&message); } I'm compiling like so: g++ -L/usr/local/lib -lxerces-c -I/usr/local/include -c MySAXHandler.cpp I've looked through the HandlerBase and it is defined, so I don't know why I can't derive a class from it? Do I have to override all the virtual functions in HandlerBase? I'm kinda new to C++. Thanks in advance.

  • How to determine one to many column name from entity type

    - by snicker
    I need a way to determine the name of the column used by NHibernate to join one-to-many collections from the collected entity's type. I need to be able to determine this at runtime. Here is an example: I have some entities: namespace Entities { public class Stable { public virtual int Id {get; set;} public virtual string StableName {get; set;} public virtual IList<Pony> Ponies { get; set; } } public class Dude { public virtual int Id { get; set; } public virtual string DudesName { get; set; } public virtual IList<Pony> PoniesThatBelongToDude { get; set; } } public class Pony { public virtual int Id {get; set;} public virtual string Name {get; set;} public virtual string Color { get; set; } } } I am using NHibernate to generate the database schema, which comes out looking like this: create table "Stable" (Id integer, StableName TEXT, primary key (Id)) create table "Dude" (Id integer, DudesName TEXT, primary key (Id)) create table "Pony" (Id integer, Name TEXT, Color TEXT, Stable_id INTEGER, Dude_id INTEGER, primary key (Id)) Given that I have a Pony entity in my code, I need to be able to find out: A. Does Pony even belong to a collection in the mapping? B. If it does, what are the column names in the database table that pertain to collections In the above instance, I would like to see that Pony has two collection columns, Stable_id and Dude_id.

  • PHP + CURL How to get file name

    - by Gunjan
    I'm trying to download users profile picture from facebook in PHP using this function public static function downloadFile($url, $options = array()) { if (!is_array($options)) $options = array(); $options = array_merge(array( 'connectionTimeout' => 5, // seconds 'timeout' => 10, // seconds 'sslVerifyPeer' => false, 'followLocation' => true, // if true, limit recursive redirection by 'maxRedirs' => 2, // setting value for "maxRedirs" ), $options); // create a temporary file (we are assuming that we can write to the system's temporary directory) $tempFileName = tempnam(sys_get_temp_dir(), ''); $fh = fopen($tempFileName, 'w'); $curl = curl_init($url); curl_setopt($curl, CURLOPT_FILE, $fh); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, $options['connectionTimeout']); curl_setopt($curl, CURLOPT_TIMEOUT, $options['timeout']); curl_setopt($curl, CURLOPT_HEADER, false); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, $options['sslVerifyPeer']); curl_setopt($curl, CURLOPT_FOLLOWLOCATION, $options['followLocation']); curl_setopt($curl, CURLOPT_MAXREDIRS, $options['maxRedirs']); curl_exec($curl); curl_close($curl); fclose($fh); return $tempFileName; } The problem is it saves the file in the /tmp directory with a random name and without the extension. How can I get the original name of the file (I'm more interested in the original extension) The important things here are: The url actually redirects to image so i cant get it from original url the final url does not have the file name in headers

  • adb doesn't get phone's device name/number

    - by Dona Hertel
    Okay, I have a strange problem I haven't seen listed anywhere. I'm developing an android app and I would like to run it on my Huawei Ascend. I have set up a file in /etc/udev/90-android.rules with the line: SUBSYSTEM=="usb", SYSFS{idVendor}=="12d1", MODE="0666" where '12d1' is the correct vendor ID for this phone (I verified this with 'lsusb' command). When I plug in the phone (it does have debugging on) and restart the adb server I get a connection but the name field does not get set. The output to 'adb devices' is: List of devices attached \n ???????????? device Plugging and unplugging the cable doesn't resolve this. Neither does restarting the adb server. Nor does a total reboot of both my computer or the phone. This is fine as I can get logs and a shell. The problem is that in the eclipse plugin, the device's name is list as "????????????" and so when it tries connect, it quits with an error message of 'device not found' even though the device is listed and 'online'. Is there something else I need to do? Do I need to set the name of the device somehow? cocofan P.S.: The app has 'debuggable' set to true in the manifest file.
