  • Netbeans and EOF

    - by sqlnoob
    Hey there, Java, ANTLR and Netbeans newbie here. I have installed a jdk and netbeans. I started a new project on netbeans 6.8 and i have added the antlr-3.2.jar as a library. I also created a lexer and parser class using AntlrWorks. These classes are named ExprParser.java and ExprLexer.java. I copied them into a directory named path-to-netbeans-project/src/parsers. I have a main file: package javaapplication2; import org.antlr.runtime.*; import parsers.*; public class Main { public static void main(String[] args) throws Exception{ ANTLRInputStream input = new ANTLRInputStream(System.in); ExprLexer lexer = new ExprLexer(input); CommonTokenStream tokens = new CommonTokenStream(lexer); ExprParser parser = new ExprParser(tokens); parser.prog(); } } The application builds fine. The book I'm reading says I should run the program and type in some stuff and then press Ctrl+Z (I'm on windows) to send EOF to the console. Problem is that nothing happens when I press Ctrl+z in the netbeans console. When I run from the command line, ctrl+z works fine. This is probably WAY too much information, but I can't figure it out. Sorry. Probably not a good idea to learn 3 new technologies at once.

  • rename files with the same name

    - by snorpey
    Hi. I use the following function to rename thumbnails. For example, if I upload a file called "image.png" to an upload folder, and this folder already has a file named "image.png" in it, the new file automatically gets renamed to "image-copy-1.png". If there also is a file called "image-copy-1.png" it gets renamed to "image-copy-2.png" and so on. The following function returns the new filename. At least that's what it is supposed to do... The renaming doesn't seeem to work correctly, though. Sometimes it produces strange results, like: 1.png 1-copy-1.png 1-copy-2.png 1-copy-2-copy-1.png 1-copy-2-copy-3.png I hope you understand my problem, despite my description being somewhat complex... Can you tell me what went wrong here? (bonus question: Is regular expressions the right tool for doing this kind of stuff?) <?php function renameDuplicates($path, $file) { $fileName = pathinfo($path . $file, PATHINFO_FILENAME); $fileExtension = "." . pathinfo($path . $file, PATHINFO_EXTENSION); if(file_exists($path . $file)) { $fileCopy = $fileName . "-copy-1"; if(file_exists($path . $fileCopy . $fileExtension)) { if ($contains = preg_match_all ("/.*?(copy)(-)(\\d+)/is", $fileCopy, $matches)) { $copyIndex = $matches[3][0]; $fileName = substr($fileCopy, 0, -(strlen("-copy-" . $copyIndex))) . "-copy-" . ($copyIndex + 1); } } else { $fileName .= "-copy-1"; } } $returnValue = $fileName . $fileExtension; return $returnValue; }?>

  • Getting Google results in Java? Need help!

    - by Cris Carter
    Hello. Right now, I'm trying to get the results from Google in Java, by searching for a term. I'm using a desktop program, not an applet. That in itself isn't complicated. but then Google gave me a 403 error. Anyways, I added referrer and User Agent and then it worked. Now, my problem is that I don't get the results page from Google. Instead, I get their script which gets the results page. My code right now simply uses a GET request on "http://www.google.com/search?q=" + Dork; Then it outputs each line. Here is what I get when I run my program: <.!doctype html<.head<.titledork - Google Search<./title<.scriptwindow.google={kEI:"9myaS-Date).getTime()}}};try{}catch(u){}window.google.jsrt_kill=1; align:center}#logo{display:block;overflow:hidden;position:relative;width:103px;height:37px; <./ script<./div Lots of stuff like that. I shortened it (A LOT) and put in dots to fit it here. So my big question is: How do I turn this whole mess into the nice results page I get when searching Google with a browser? Any help would be seriously appreciated, and I really need the answer fast. Also, please keep in mind that I do NOT want to use Google's API for this. Thanks in advance!

  • ajax call to servlet puzzler

    - by vector
    Greetings! I'm having a problem getting a text value of a captcha from a servlet through ajax call. When my captcha gets created, its text value is written to session, but after refreshing the image itself though ajax call, I only get one old value of the text. Refreshing the image itself works ok, but I'm stuck getting the correct values from the session on subsequent call. On page reload I get both the new image and its new text value, no joy with ajax though. This works great for the image refresh: $("#asos").attr("src", "/ImageServlet?="+((new Date()).getTime()) ) This call to another method to get text value gives me old stuff: $.ajax({ url:"checkCaptcha", type:"GET", cache: false, success: function( data) { alert(data); } }); Any feedback will be appreciated. ps: here's the meat of the method getting the call: PrintWriter out = response.getWriter(); response.setContentType("text/html"); response.setDateHeader("Expires", 0 ); // Set standard HTTP/1.1 no-cache headers. response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate"); // Set IE extended HTTP/1.1 no-cache headers (use addHeader). response.addHeader("Cache-Control", "post-check=0, pre-check=0"); // Set standard HTTP/1.0 no-cache header. response.setHeader("Pragma", "no-cache"); out.print( request.getSession( ).getAttribute("randomPixValue") ); out.close();

  • pgsql.so is not loaded in PHP

    - by Obay
    Hi, I've been tasked to create a PHP app which accesses an existing PostgreSQL database. This is my first time working with Postgre, not to mention the PHP has already been installed in the Linux box on which the app is supposed to run. I have no experience setting up this stuff, I just code. My question is that I can't seem to get the Postgre extension working in PHP. I checked the php.ini file, there were no "extension=..." lines. So I added "extension=pgsql.so". I then checked the "extension_dir" and found that there were only 2 files in there (ldap.so, phpcups.so), I added a pgsql.so file taken from another Linux box. I restarted httpd. And it does not work. I couldn't find any "pgsql" or "postgre" in phpinfo(). Forgive my noobness. I know too little Linux. I would really appreciate it if you can point me to the right direction.

  • ai: Determining what tests to run to get most useful data

    - by Sai Emrys
    This is for http://cssfingerprint.com I have a system (see about page on site for details) where: I need to output a ranked list, with confidences, of categories that match a particular feature vector the binary feature vectors are a list of site IDs & whether this session detected a hit feature vectors are, for a given categorization, somewhat noisy (sites will decay out of history, and people will visit sites they don't normally visit) categories are a large, non-closed set (user IDs) my total feature space is approximately 50 million items (URLs) for any given test, I can only query approx. 0.2% of that space I can only make the decision of what to query, based on results so far, ~10-30 times, and must do so in <~100ms (though I can take much longer to do post-processing, relevant aggregation, etc) getting the AI's probability ranking of categories based on results so far is mildly expensive; ideally the decision will depend mostly on a few cheap sql queries I have training data that can say authoritatively that any two feature vectors are the same category but not that they are different (people sometimes forget their codes and use new ones, thereby making a new user id) I need an algorithm to determine what features (sites) are most likely to have a high ROI to query (i.e. to better discriminate between plausible-so-far categories [users], and to increase certainty that it's any given one). This needs to take into balance exploitation (test based on prior test data) and exploration (test stuff that's not been tested enough to find out how it performs). There's another question that deals with a priori ranking; this one is specifically about a posteriori ranking based on results gathered so far. Right now, I have little enough data that I can just always test everything that anyone else has ever gotten a hit for, but eventually that won't be the case, at which point this problem will need to be solved. I imagine that this is a fairly standard problem in AI - having a cheap heuristic for what expensive queries to make - but it wasn't covered in my AI class, so I don't actually know whether there's a standard answer. So, relevant reading that's not too math-heavy would be helpful, as well as suggestions for particular algorithms. What's a good way to approach this problem?

  • WPF HiercharchicalDataTemplate.DataType: How to react on interfaces?

    - by David Schmitt
    Problem I've got a collection of IThings and I'd like to create a HierarchicalDataTemplate for a TreeView. The straightforward DataType={x:Type local:IThing} of course doesn't work, probably because the WPF creators didn't want to handle the possible ambiguities. Since this should handle IThings from different sources at the same time, referencing the implementing class is out of question. Current solution For now I'm using a ViewModel which proxies IThing through a concrete implementation: public interface IThing { string SomeString { get; } ObservableCollection<IThing> SomeThings { get; } // many more stuff } public class IThingViewModel { public IThing Thing { get; } public IThingViewModel(IThing it) { this.Thing = it; } } <!-- is never applied --> <HierarchicalDataTemplate DataType="{x:Type local:IThing}"> <!-- is applied, but looks strange --> <HierarchicalDataTemplate DataType="{x:Type local:IThingViewModel}" ItemsSource="{Binding Thing.SomeThings}"> <TextBox Text="{Binding Thing.SomeString}"/> </HierarchicalDataTemplate> Question Is there a better (i.e. no proxy) way?

  • Use localeURL middleware with apache prefix

    - by Olivier R.
    Good morning everyone, I Got a question about localeURL usage. Everything works great for me with url like this : www.mysite.com/ If I type www.mysite.com/ in adress bar, it turns correctly in www.mysite.com/en/ for example. If I use the view change_locale, it's also all right (ie change www.mysite.com/en/ in www.mysite.com/fr/). But my application use apache as server, and use a prefix for the site, that gives url like this : www.mysite.com/prefix/ If I type www.mysite.com/prefix/ in the adress bar, the adress turns into www.mysite.com/en/ without prefix (so 404) I change code of view to manage our settings.SERVER_PREFIX value : def change_locale(request) : """ Redirect to a given url while changing the locale in the path The url and the locale code need to be specified in the request parameters. O. Rochaix; Taken from localeURL view, and tuned to manage : - SERVER_PREFIX from settings.py """ next = request.REQUEST.get('next', None) if not next: next = request.META.get('HTTP_REFERER', None) if not next: next = settings.SERVER_PREFIX + '/' next = urlsplit(next).path prefix = False if settings.SERVER_PREFIX!="" and next.startswith(settings.SERVER_PREFIX) : prefix = True next = "/" + next.lstrip(settings.SERVER_PREFIX) _, path = utils.strip_path (next) if request.method == 'POST': locale = request.POST.get('locale', None) if locale and check_for_language(locale): path = utils.locale_path(path, locale) if prefix : path = settings.SERVER_PREFIX + path response = http.HttpResponseRedirect(path) return response with this customized view, i'm able to correctly change language, but i'm not sure that's the right way of doing stuff. Is there any option on localeURL to manage prefix of apache ?

  • Why user control with code behind file doesn't want to compile under MVC2?

    - by kyrisu
    I have user control in my MVC2 app placed in the Content folder (it's not supposed to be a view, just reusable part of the app). UserControl1.ascx looks like: <@ Control AutoEventWireup="true" Language="C#" CodeFile="~/Content/UserControl1.ascx.cs" Inherits="MVCDrill.Content.UserControl1" %> <div runat="server" id="mydiv"> <asp:LinkButton id="lb_text" runat="server"></asp:LinkButton> </div> UserControl1.ascx.cs looks like: using System; using System.Web; using System.Web.UI; namespace MVCDrill.Content { public class UserControl1 : UserControl { public string Text { get { return this.lb_text.Text; } set { this.lb_text.Text = value; } } } } I'm pretty sure this kind of stuff compiled under webforms but I'm getting compilation error: 'MVCDrill.Content.UserControl1' does not contain a definition for 'lb_text' and no extension method 'lb_text' accepting a first argument of type 'MVCDrill.Content.UserControl1' could be found (are you missing a using directive or an assembly reference?) Am I missing something? How to change it (what is the alternative) in MVC2 ? p.s. Intellisense sees lb_text with no problem. I've tried with different controls with the same outcome.

  • MVC 2 Data annotations problem

    - by Louzzzzzz
    Hi. Going mad now. I have a MVC solution that i've upgraded from MVC 1 to 2. It all works fine.... except the Validation! Here's some code: In the controller: using System; using System.Collections.Generic; using System.Globalization; using System.Linq; using System.Security.Principal; using System.Web; using System.Web.Mvc; using System.Web.Security; using System.Web.UI; using MF.Services.Authentication; using System.ComponentModel; using System.ComponentModel.DataAnnotations; namespace MF.Controllers { //basic viewmodel public class LogOnViewData { [Required] public string UserName { get; set; } [Required] public string Password { get; set; } } [HandleError] public class AccountController : Controller { [HttpPost] public ActionResult LogOn(LogOnViewData lvd, string returnUrl) { if (ModelState.IsValid) { //do stuff - IsValid is always true } } } } The ModelState is always valid. The model is being populated correctly however. Therefore, if I leave both username and password blank, and post the form the model state is still valid. Argh! Extra info: using structure map for IoD. Previously, before upgrading to MVC 2 was using the MS data annotation library so had this in my global.asax.cs: ModelBinders.Binders.DefaultBinder = new Microsoft.Web.Mvc.DataAnnotations.DataAnnotationsModelBinder(); Have removed that now. I'm sure i'm doing something really basic and wrong. If someone could point it out that would be marvellous. Cheers

  • asp.net does not Redirect when in frameset

    - by Snoop Dogg
    I have developed an application on asp.net. I uploaded it to my host. lets say http://myhost/app. My manager wrapped this address into an empty frameset on http://anotherhost/somename and sets the src of frame to http://myhost/ap. And so nobody can login. When the button is hit, it posts back (browser loads stuff, progress bar fills up and ends) but nothing happens. Does not redirect. (I have set IE to alwaysAllowCookies and it now does work, but other people still cannot) I think there is something that I have no clue about framesets and ASP.NET ps: I never use frames but could not convince my manager in doing so. He likes to develop in front page :) Whatz happening? Thx in advance protected void btnLogin_Click(object sender, ImageClickEventArgs e) { Member member = Logic.DoLogin(txtUsername.Text.Trim(), txtPassword.Text.Trim()); if (null == member) { lblError.Text = "Invalid Login !"; return; } CurrentMember = member; ///CurrentMember is an inherited property that accesses Session["member"] = member Response.Redirect("Default.aspx");

  • Qt 5.3 OpenGL - vertex buffer object drawing using the core profile

    - by user3700881
    Im using Qt 5.3 to create a QWindow to do some basic rendering stuff. The QWindow is declared like this: class OpenGLWindow : public QWindow, protected QOpenGLFunctions_3_3_Core { Q_OBJECT ... } It is initialized in the constructor: OpenGLWindow::OpenGLWindow(QWindow *parent) : QWindow(parent) { QSurfaceFormat format; format.setVersion(3,3); format.setProfile(QSurfaceFormat::CoreProfile); this->setSurfaceType(OpenGLSurface); this->setFormat(format); this->create(); _context = new QOpenGLContext; _context->setFormat(format); _context->create(); _context->makeCurrent(this); this->initializeOpenGLFunctions(); ... } And that's the rendering code: void OpenGLWindow::render() { if(!isExposed()) return; _context->makeCurrent(this); glClear(GL_COLOR_BUFFER_BIT); glUseProgram(_shaderProgram); glBindBuffer(GL_ARRAY_BUFFER, _positionBufferObject); glEnableVertexAttribArray(0); glVertexAttribPointer(0, 4, GL_FLOAT, GL_FALSE, 0, 0); glDrawArrays(GL_TRIANGLES, 0, 3); glDisableVertexAttribArray(0); glUseProgram(0); _context->swapBuffers(this); } I am trying to draw a simple triangle using a vertex and fragment shader. The problem is that the triangle is not showing up when the core profile is set. Only when I set the OpenGL version to 2.0 or when I use the compatibility profile, it shows up. From my point of view that doesn't make any sense because I am not using fixed functionality at all. What am I missing?

  • Overriding windows authentication for a .NET application

    - by JoshReedSchramm
    I have a .NET application where the homepage (default.aspx) should be accessible by anyone. There is also a reporting page (reporting.aspx) that I want to secure via windows authentication and only allow access to a particular set of AD groups. Right now the way my web.config is setup it is securing the reporting page but on the home page it prompts the user for login credentials. If they hit esc they can continue to the page though so it isnt actually securing it. I need to prevent it from prompting the user. How do i need to setup my config. Here is what i have now - <system.web> <authentication mode="Windows" /> <identity impersonate="true" /> <authorization> <allow roles="BUILTIN\Administrators, DomainName\Manager" /> <deny users="?" /> </authorization> ...MORE STUFF... </system.web> <location path="default.aspx"> <system.web> <identity impersonate="false" /> <authorization> <allow users="*"/> </authorization> </system.web> </location>

They also have entries in an Albums table (album name/album cover etc), referencing the artist table using the artist id as a foreign key.

  • sqrt(int_value + 0.0) -- Does it have a purpose?

    - by Earlz
    Hello, while doing some homework in my very strange C++ book, which I've been told before to throw away, had a very peculiar code segment. I know homework stuff always throws in extra "mystery" to try to confuse you like indenting 2 lines after a single-statement for-loop. But this one I'm confused on because it seems to serve some real-purpose. basically it is like this: int counter=10; ... if(pow(floor(sqrt(counter+0.0)),2) == counter) ... I'm interested in this part especially: sqrt(counter+0.0) Is there some purpose to the +0.0? Is this the poormans way of doing a static cast to a double? Does this avoid some compiler warning on some compiler I do not use? The entire program printed the exact same thing and compiled without warnings on g++ whenever I left out the +0.0 part. Maybe I'm not using a weird enough compiler? Edit: Also, does gcc just break standard and not make an error for Ambiguous reference since sqrt can take 3 different types of parameters? [earlz@EarlzBeta-~/projects/homework1] $ cat calc.cpp #include <cmath> int main(){ int counter=0; sqrt(counter); } [earlz@EarlzBeta-~/projects/homework1] $ g++ calc.cpp /usr/lib/libstdc++.so.47.0: warning: strcpy() is almost always misused, please use strlcpy() /usr/lib/libstdc++.so.47.0: warning: strcat() is almost always misused, please use strlcat() [earlz@EarlzBeta-~/projects/homework1] $

  • IoC & Interfaces Best Practices

    - by n8wrl
    I'm experimenting with IoC on my way to TDD by fiddling with an existing project. In a nutshell, my question is this: what are the best practices around IoC when public and non-public methods are of interest? There are two classes: public abstract class ThisThingBase { public virtual void Method1() {} public virtual void Method2() {} public ThatThing GetThat() { return new ThatThing(this); } internal virtual void Method3() {} internal virtual void Method4() {} } public class Thathing { public ThatThing(ThisThingBase thing) { m_thing = thing; } ... } ThatThing does some stuff using its ThisThingBase reference to call methods that are often overloaded by descendents of ThisThingBase. Method1 and Method2 are public. Method3 and Method4 are internal and only used by ThatThings. I would like to test ThatThing without ThisThing and vice-versa. Studying up on IoC my first thought was that I should define an IThing interface, implement it by ThisThingBase and pass it to the ThatThing constructor. IThing would be the public interface clients could call but it doesn't include Method3 or Method4 that ThatThing also needs. Should I define a 2nd interface - IThingInternal maybe - for those two methods and pass BOTH interfaces to ThatThing?

  • How to serialize a protected property in wcf

    Hello, i need some help with wcf serializing. I have two classes Person and Address. The Address class looks like this: public class Adresa : IExtensibleDataObject { private Guid _id; [DataMember] protected virtual Guid Id { get { return _id; } set { _id = value; } } private ExtensionDataObject _extensionData; [DataMember] public virtual ExtensionDataObject ExtensionData { get { return _extensionData; } set { _extensionData = value; } } private string _street; [DataMember] public virtual string Street { get { return this._cUTAM; } set { this._cUTAM = value; } } private string _number; [DataMember] public virtual string Number { get { return this._number; } set { this._number = value; } } private string _postalCode; [DataMember] public virtual string PostalCode { get { return this._postalCode; } set { this._postalCode = value; } } // and some other stuff related to the address } The Person class looks like this: public class PersoanaFizica :IExtensibleDataObject { private Guid _id; [DataMember] protected virtual Guid Id { get { return _id; } set { _id = value; } } private ExtensionDataObject _extensionData; [DataMember] public virtual ExtensionDataObject ExtensionData { get { return _extensionData; } set { _extensionData = value; } } private string _firstName; [DataMember] public virtual string FirstName { get { return this._firstName; } set { this._firstName = value; } } private string _lastName; [DataMember] public virtual string LastName { get { return this._lastName; } set { this._lastName = value; } } } The problem is that when the wcf client the data the Id properties are set to a bunch of zeros ( something like 000000-0000-000000-0000000). Any ideas on why this is happening? Thanks, Denis.

  • PJSIP Custom Registration Header (iOS)

    - by Daniel Redington
    I am attempting to setup SIP communication with an internal server (using the PJSIP library), however, this server requires a custom header field with a specified header value for the REGISTRATION call. For example's sake we'll call this required header "MyHeader". From what I've found, the pjsua_acc_add() function will add an account and register it to the server using a config struct. The parameter "reg_hdr_list" of the config struct has the description "The optional custom SIP headers to be put in the registration request." Which sounds like exactly what I need, however doesn't seem to have any effect on the call itself. Here's what I have so far: pjsua_acc_config cfg; pjsua_acc_config_default(&cfg); //...Some other config stuff related to the server... pjsip_hdr test; test.name = pj_str("MyHeader"); test.sname = pj_str("MyHdr"); test.type = PJSIP_H_OTHER; test.prev = cfg.reg_hdr_list.prev; test.next = cfg.reg_hdr_list.next; cfg.reg_hdr_list = test; pj_status_t status; status = pjsua_acc_add(&cfg, PJ_TRUE, &acc_id); From the server side, there are no extra header fields or anything. And the struct that is used to define the header (pjsua_hdr) has no "value" or equivalent field, so even if it did create the header, how does it set the value? Here's the refrence for the header list definition: Link And the reference for the header struct: Link Any help would be greatly appreciated!

  • Info on type family instances

    - by yairchu
    Intro: While checking out snoyman's "persistent" library I found myself wanting ghci's (or another tool) assistance in figuring out stuff. ghci's :info doesn't seem to work as nicely with type-families and data-families as it does with "plain" types: > :info Maybe data Maybe a = Nothing | Just a -- Defined in Data.Maybe ... > :info Persist.Key Potato -- "Key Potato" defined in example below data family Persist.Key val -- Defined in Database.Persist ... (no info on the structure/identity of the actual instance) One can always look for the instance in the source code, but sometimes it could be hard to find it and it may be hidden in template-haskell generated code etc. Code example: {-# LANGUAGE FlexibleInstances, GeneralizedNewtypeDeriving, MultiParamTypeClasses, TypeFamilies, QuasiQuotes #-} import qualified Database.Persist as Persist import Database.Persist.Sqlite as PSqlite PSqlite.persistSqlite [$persist| Potato name String isTasty Bool luckyNumber Int UniqueId name |] What's going on in the code example above is that Template-Haskell is generating code for us here. All the extensions above except for QuasiQuotes are required because the generated code uses them. I found out what Persist.Key Potato is by doing: -- test.hs: test = PSqlite.persistSqlite [$persist| ... -- ghci: > :l test.hs > import Language.Haskell.TH > import Data.List > runQ test >>= putStrLn . unlines . filter (isInfixOf "Key Potato") . lines . pprint where newtype Database.Persist.Key Potato = PotatoId Int64 type PotatoId = Database.Persist.Key Potato Question: Is there an easier way to get information on instances of type families and data families, using ghci or any other tool?

  • Should I go vor Arrays or Objects in PHP in a CouchDB/Ajax app?

    - by karlthorwald
    I find myself converting between array and object all the time in PHP application that uses couchDB and Ajax. Of course I am also converting objects to JSON and back (for sometimes couchdb but mostly Ajax), but this is not so much disturbing my workflow. At the present I have php objects that are returned by the CouchDB modules I use and on the other hand I have the old habbit to return arrays like array("error"="not found","data"=$dataObj) from my functions. This leads to a mixed occurence of real php objects and nested arrays and I cast with (object) or (array) if necessary. The worst thing is that I know more or less by heart what a function returns, but not what type (array or object), so I often run into type errors. My plan is now to always cast arrays to objects before returning from a function. Of course this implies a lot of refactoring. Is this the right way to go? What about the conversion overhead? Other ideas or tips? Edit: Kenaniah's answer suggests I should go the other way, this would mean I'd cast everything to arrays. And for all the Ajax / JSON stuff and also for CouchDB I would use $myarray = json_decode($json_data,$assoc = false) Even more work to change all the CouchDB and Ajax functions but in the end I have better code.

  • How to compile a C DLL for 64 bit with Visual Studio 2010?

    - by Daren Thomas
    I have a DLL written in C in source code. This is the code for the General Polygon Clipper (in case you are interested). I'm using it in a C# project via the C# wrapper provided on the homepage. This comes with a precompiled DLL. Since switching to a 64bit Development machine with Visual Studio 2010 and Windows 7 64 bit, the application won't run anymore. This is the error I get: An attempt was made to load a program with an incorrect format. This is because of DLLImporting the 32bit gpc.dll, as I have gathered from stuff found on the web. I assume this will all go away if I recompile the DLL to 64bit, but can't for the love of me figure out how to do so. My C skills are basic, in that I can write a C program with the GNU tools, but have no experience with various compilers / processors / IDEs etc. I believe I could port this to C#. By that I mean I trust myself to actually pull it off. But I'd prefer not to, since it is a lot of work that I'd prefer a compiler to do for me ;)

    Been away from C++ for a few years and am getting a linker error from the following code: Gene.h #ifndef GENE_H_INCLUDED #define GENE_H_INCLUDED template <typename T> class Gene { public: T getValue(); void setValue(T value); void setRange(T min, T max); private: T value; T minValue; T maxValue; }; #endif // GENE_H_INCLUDED Gene.cpp #include "Gene.h" template <typename T> T Gene<T>::getValue() { return this->value; } template <typename T> void Gene<T>::setValue(T value) { if(value >= this->minValue && value <= this->minValue) { this->value = value; } } template <typename T> void Gene<T>::setRange(T min, T max) { this->minValue = min; this->maxValue = max; } Using Code::Blocks and GCC if it matters to anyone. Also, clearly porting some GA stuff to C++ for fun and practice.

  • Aero Snap not working for my application

    - by Magnus Österlind
    I have a problem with Aero Snap not working with the application I'm working on (Windows desktop, native C++ application), and I'm a bit confused as to what's happening, as it seems like it should just work, out of the box. I've used Spy++ on a mininal win32 application, and get the following messages when I press Win-Left: <00070 00030D1C P WM_KEYDOWN nVirtKey:VK_LWIN cRepeat:1 ScanCode:5B fRepeat:0 fUp:0 <00071 00030D1C P WM_KEYDOWN nVirtKey:VK_LWIN cRepeat:1 ScanCode:5B fRepeat:1 fUp:0 <00072 00030D1C P WM_KEYDOWN nVirtKey:VK_LWIN cRepeat:1 ScanCode:5B fRepeat:1 fUp:0 <00088 00030D1C S WM_GETMINMAXINFO lpmmi:0043FCBC <00089 00030D1C R WM_GETMINMAXINFO lpmmi:0043FCBC <00090 00030D1C S WM_WINDOWPOSCHANGING lpwp:0043FCC4 <00091 00030D1C S WM_GETMINMAXINFO lpmmi:0043F8E8 <00092 00030D1C R WM_GETMINMAXINFO lpmmi:0043F8E8 <00093 00030D1C R WM_WINDOWPOSCHANGING .. and so on So I can see that the WM_KEYDOWN for the left key isn't reaching the application, but I'm getting the aero snap "resize window" stuff instead. When I Spy++ my application, I can see that the left key isn't being "intercepted", but instead being passed on to the application, so I don't get any snapping goodness. <00043 000F0F12 P WM_KEYDOWN nVirtKey:VK_LWIN cRepeat:1 ScanCode:5B fRepeat:0 fUp:0 <00044 000F0F12 P WM_KEYDOWN nVirtKey:VK_LWIN cRepeat:1 ScanCode:5B fRepeat:1 fUp:0 <00045 000F0F12 P WM_KEYDOWN nVirtKey:VK_LWIN cRepeat:1 ScanCode:5B fRepeat:1 fUp:0 <00060 000F0F12 P WM_KEYUP nVirtKey:VK_LEFT cRepeat:1 ScanCode:4B fRepeat:0 fUp:1 I'm going to dig into the cores of our message handling and see what's going on, but I'll take all the tips I can get :)

  • Open source file upload with no timeout on IIS6 with ASP, ASP.NET 2.0 or PHP5

    - by Christopher Done
    I'm after a cross-platform cross-browser way of uploading files such that there is no timeout. Uploads aren't necessarily huge -- some just take a long time to upload because of the uploader's slow connection -- but the server times out anyway. I hear that there are methods to upload files in chunks so that somehow the server decides not to timeout the upload. After searching around all I can see is proprietary upload helpers and Java and Flash (SWFUpload) widgets that aren't cross-platform, don't upload in chunks, or aren't free. I'd like a way to do it in any of these platforms (ASP, ASP.NET 2.0 or PHP5), though I am not very clued up on all this .NET class/controller/project/module/visual studio/compile/etc stuff, so some kind of runnable complete project that runs on .NET 2.0 would be helpful. PHP and ASP I can assume will be more straight-forward. Unless I am completely missing something, which I suspect/hope I am, reasonable web uploads are bloody hard work in any language or platform. So my question is: how can I perform web browser uploads, cross-platform, so that they don't timeout, using free software? Is it possible at all?

  • AVAudioPlayer working in Simulator, but not on device

    - by cannyboy
    My mp3 playing code is: NSError *error; soundObject = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:audioPathString] error:&error]; if (soundObject == nil) NSLog(@"%@", [error description]); soundObject.delegate = self; soundObject.numberOfLoops = 0; soundObject.volume = 1.0; NSLog(@"about to play"); [soundObject prepareToPlay]; [soundObject play]; NSLog(@"[soundObject play];"); The mp3 used to play fine, and it still does on the simulator. But not on the device. I've recently added some sound recording code (not mine) to the software. It uses AudioQueue stuff which is slightly beyond me. Does that conflict with AVAudioPlayer? Or what could be the problem? I've noticed that as soon as the audiorecording code starts working, I can't adjust the volume on the device anymore, so maybe it blocks the audio playback?. EDIT The solution seems to be to put this in my code. I put it in applicationDidFinishLaunching: [[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayAndRecord error: nil]; UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker; AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride); The first line allows both play and record, whilst the other lines apparently reroute things to make the volume louder. All audio code is voodoo to me.
