  • GridPanel in Extjs is not loaded

    - by pho3nix
    I have this code in my application, but this not load any data. Data is accessible but wont display in my gridpanel, anyone have idea, why? Ext.onReady(function () { Ext.QuickTips.init(); Ext.form.Field.prototype.msgTarget = 'side'; var btnAdd = new Ext.Button({ id: 'btnAdd', text: 'Adicionar', iconCls: 'application_add', handler: function (s) { } }); var btnEdit = new Ext.Button({ id: 'btnEdit', text: 'Editar', iconCls: 'application_edit', handler: function (s) { } }); var btnRemove = new Ext.Button({ id: 'btnRemove', text: 'Apagar', iconCls: 'application_delete', handler: function (s) { } }); var tbar = new Ext.Toolbar({ items: [btnAdd, btnEdit, btnRemove] }); var formFind = new Ext.FormPanel({ height: 100 }); var store = new Ext.data.JsonStore({ remoteSort: true, idProperty: 'ContentId', root: 'rows', totalProperty: 'results', fields: [ { name: 'ContentId', type: 'int' }, { name: 'Name' }, { name: 'Version' }, { name: 'State' }, { name: 'CreatedDateTime' }, { name: 'PublishedDateTime'}, { name: 'CreatedByUser' }, { name: 'PublishedByUser' } ], proxy: new Ext.data.ScriptTagProxy({ url: '/Admin/ArticleList' }) }); store.setDefaultSort('ContentId', 'desc'); var paging = new Ext.PagingToolbar({ store: store, pageSize: 25, displayInfo: true, displayMsg: 'Foram encontrados {2} registos. Mostrando {0} de {1}', emptyMsg: "Nenhum registo encontrado." }); var grid = new Ext.grid.GridPanel({ id: 'grid', height: 700, store: store, loadMask: true, loadingText: 'Carregando...', autoHeight: true, cm: new Ext.grid.ColumnModel ([ { id: 'ContentId', dataIndex: 'ContentId', header: 'Identif.', width: 60, sortable: true }, { id: 'Name', dataIndex: 'Name', header: 'Titulo', width: 75, sortable: true }, { id: 'Version', dataIndex: 'Version', header: 'Versão', width: 75, sortable: true }, { id: 'State', dataIndex: 'State', header: 'Estado', width: 75, sortable: true }, { id: 'CreatedDateTime', dataIndex: 'CreatedDateTime', header: 'Data de Criação', width: 85, sortable: true }, { id: 'PublishedDateTime', dataIndex: 'PublishedDateTime', header: 'Data de Publicação', width: 75, sortable: true }, { id: 'CreatedByUser', dataIndex: 'CreatedByUser', header: 'Criado por', width: 75, sortable: true }, { id: 'PublishedByUser', dataIndex: 'PublishedByUser', header: 'Publicado por', width: 85, sortable: true } ]), stripeRows: true, viewConfig: { forceFit: true }, bbar: paging }); var panel = new Ext.Panel({ id: 'panel', renderTo: Ext.getBody(), layout: 'fit', tbar: tbar, items: [grid] }); store.load(); // trigger the data store load });

  • What java web framework best accomodates web ui designers?

    - by Brian Laframboise
    What Java web framework out there best supports a role of "web UI designer", that is, lets you: Use popular web design tools (xhtml validators, css editors, what have you) on your views/pages View changes without running on a server Rapidly prototype different UI options Supports a (somewhatly) clean separation between "developer" and "designer" (terminology intentionally vague) We, like many others, have found these capabilities sorely lacking in our large, legacy Struts 1.x apps that use lots of JSP fragments and includes. We've decided to port our apps to a JSR-168/268 portal environment, but we have not decided on what Java web framework will power the portlets. We're open to any kind (action-based, component-based, etc) and a key criterion is how well it supports the role described above. I'm intrigued by Tapestry which claims that its views are XHTML compliant pages (that simply have extra Tapestry-specific attributes added onto them to be processed at runtime). This sounds like it would play well with a web ui designer's toolkit. However, I'd like to know if this is what actually happens in the real world, or if compromises are necessary. Of course, if there's something much better than Tapestry, I'd love to hear about it!

  • javascript class calling XMLHttpRequest internally, then handling onreadystatechange

    - by Radu M
    this thing almost works: function myClass(url) { this.source = url; this.rq = null; this.someOtherProperty = "hello"; // open connection to the ajax server this.start = function() { if (window.XMLHttpRequest) { this.rq = new XMLHttpRequest(); if (this.rq.overrideMimeType) this.rq.overrideMimeType("text/xml"); } else this.rq = new ActiveXObject("Microsoft.XMLHTTP"); try { this.rq.onreadystatechange = connectionEvent; this.rq.open("GET", this.source, true); this.rq.send(null); this.state = 1; } catch (err) { // some error handler here } } function connectionEvent() { alert("i'm here"); alert("this doesnt work: " + this.someOtherProperty); } } // myClass so it's nothing more than having the XMLHttpRequest object as a member of my class, instead of globally defined, and invoking it in the traditional way. however, inside my connectionEvent callback function, the meaning of "this" is lost, even though the function itself is scoped inside myClass. i also made sure that the object that i instantiate from myClass is kept alive long enough (declared global in the script). in all the examples of using javascript classes that i saw, "this" was still available inside the inner functions. for me, it is not, even if i take my function outside and make it a myClass.prototype.connectionEvent. what am i doing wrong? thank you.

  • Silverlight HttpWebRequest.Create hangs inside async block

    - by jack2010
    I am trying to prototype a Rpc Call to a JBOSS webserver from Silverlight (4). I have written the code and it is working in a console application - so I know that Jboss is responding to the web request. Porting it to silverlight 4, is causing issues: let uri = new Uri(queryUrl) // this is the line that hangs let request : HttpWebRequest = downcast WebRequest.Create(uri) request.Method <- httpMethod; request.ContentType <- contentType It may be a sandbox issue, as my silverlight is being served off of my file system and the Uri is a reference to the localhost - though I am not even getting an exception. Thoughts? Thx UPDATE 1 I created a new project and ported my code over and now it is working; something must be unstable w/ regard to the F# Silverlight integration still. Still would appreciate thoughts on debugging the "hanging" web create in the old model... UPDATE 2 let uri = Uri("http://localhost./portal/main?isSecure=IbongAdarnaNiFranciscoBalagtas") // this WebRequest.Create works fine let req : HttpWebRequest = downcast WebRequest.Create(uri) let Login = async { let uri = new Uri("http://localhost/portal/main?isSecure=IbongAdarnaNiFranciscoBalagtas") // code hangs on this WebRequest.Create let request : HttpWebRequest = downcast WebRequest.Create(uri) return request } Login |> Async.RunSynchronously I must be missing something; the Async block works fine in the console app - is it not allowed in the Silverlight App?

  • Are there any applications written in the Io programming language? (Or, distributing Io applications

    - by Rayne
    I've recently become interested in prototype-based OOP, and I've been playing with Io and Ioke. Distributing an application with Ioke is simple. It's on the JVM. Need I say more? However, I'm absolutely stumped as to how one would distribute an Io application, especially on Windows. It's not like you can have end-users compile Io to run your application. I was actually shocked the Io has gone for 8 years without forming some sort of standards for things like distribution. Ruby has gems, Java has jars, and so on. The worse thing about it is, I can't find a single application written in Io to maybe steal ideas on distribution from. Maybe I suck at google searching (Io is a horrible search name, by the way ;P). Is there any sort of canonical way to distribute Io applications? Are there even any Io applications in existence, or am I just missing the point? I'm not sure if this should be community wiki or not. If you think it should, comment and let me know.

  • How to automatically expand html select element in javascript

    - by xan
    I have a (hidden) html select object in my menu attached to a menu button link, so that clicking the link shows the list so you can pick from it. When you click the button, it calls some javascript to show the <select>. Clicking away from the <select> hides the list. What I really want is to make the <select> appear fully expanded, as if you had clicked on the "down" arrow, but I can't get this working. I've tried lots of different approaches, but can't make any headway. What I'm doing currently is this: <li> <a href="javascript:showlist();"><img src="/images/icons/add.png"/>Add favourite</a> <select id="list" style="display:none; onblur="javascript:cancellist()"> </select> </li> // in code function showlist() { //using prototype not jQuery $('list').show(); // shows the select list $('list').focus(); // sets focus so that when you click away it calles onblur() } I've tried calling $('list').click(). I've tried setting onfocus="this.click()" But in both cases I'm getting Uncaught TypeError: Object # has no method 'click' which is peculiar as link text says that it supports the standard functions. I've tried setting the .size = .length which works, but doesn't have the same appearance (as when you click to open the element, it floats over the rest of the page.) Does anyone have any suggestions?

  • C++ Swig Python (Embedded Python in C++) works in Release but not in Debug

    - by sambha
    Platform: Windows 7, 64 bit (x64), Visual Studio 2008 I chose Python & Swig binding as the scripting environment of the application. As a prototype, created a simple VS solution with main() which initializes Python (Py_Initalize, Py_setPyHome, etc) & executes test.py. In the same solution created another project which is a DLL of a simple class. Used SWIG to wrap this class. This DLL is the _MyClasses.pyd. test.py creates the objects of my class & calls its member functions. All this works like a charm in the Release mode. But does not work in Debug mode (even tried banging my head on the laptop ;-) ). Output of my work looks like this (in both release & debug): x64 -debug - _MyClasses.pyd - MyClasses.py - test.exe - test.py - python26.dll - python26_d.dll Note that the debug version is linked against python26_d.lib. Had to build python myself for this! test.py import MyClasses print "ello" m = MyClasses.Male("John Doe", 25) print m.getType() Male is the C++ class. The problem: Traceback (most recent call last): File "test.py", line 6, in <module> import MyClasses File "...\x64\Debug\MyClasses.py", line 25, in <module> _MyClasses = swig_import_helper() File "...\x64\Debug\MyClasses.py", line 17, in swig_imp ort_helper import _MyClasses ImportError: No module named _MyClasses [15454 refs] I am used to Makefiles & am new to Visual Studio. I dont know who the culprit is here: Swig, The debug build of Python, Visual Studio, my stupidity. Thank you in advance. It will be a great help.

  • How do I DRY up my CouchDB views?

    - by James A. Rosen
    What can I do to share code among views in CouchDB? Example 1 -- utility methods Jesse Hallett has some good utility methods, including function dot(attr) { return function(obj) { return obj[attr]; } } Array.prototype.map = function(func) { var i, r = [], for (i = 0; i < this.length; i += 1) { r[i] = func(this[i]); } return r; }; ... Where can I put this code so every view can access it? Example 2 -- constants Similarly for constants I use in my application. Where do I put MyApp = { A_CONSTANT = "..."; ANOTHER_CONSTANT = "..."; }; Example 3 -- filter of a filter: What if I want a one view that filters by "is this a rich person?": function(doc) { if (doc.type == 'person' && doc.net_worth > 1000000) { emit(doc.id, doc); } } and another that indexes by last name: function(doc) { if (doc.last_name) { emit(doc.last_name, doc); } } How can I combine them into a "rich people by last name" view? I sort of want the equivalent of the Ruby my_array.select { |x| x.person? }.select { |x| x.net_worth > 1,000,000 }.map { |x| [x.last_name, x] } How can I be DRYer?

  • rails best practices where to place unobtrusive javascript

    - by nathanvda
    Hi there, my rails applications (all 2.3.5) use a total mix of inline javascript, rjs, prototype and jquery. Let's call it learning or growing pains. Lately i have been more and more infatuated with unobtrusive javascript. It makes your html clean, in the same way css cleaned it up. But most examples i have seen are small examples, and they put all javascript(jquery) inside application.js Now i have a pretty big application, and i am thinking up ways to structure my js. I like somehow that my script is still close to the view, so i am thinking something like orders.html.erb orders.js where orders.js contains the unobtrusive javascript specific to that view. But maybe that's just me being too conservative :) I have read some posts by Yehuda Katz about this very problem here and here, where he tackles this problem. It will go through your js-files and only load those relevant to your view. But alas i can't find a current implementation. So my questions: how do you best structure your unobtrusive javascript; manage your code, how do you make sure that it is obvious from the html what something is supposed to do. I guess good class names go a long way :) how do you arrange your files, load them all in? just a few? do you use content_for :script or javascript_include_tag in your view to load the relevant scripts. Or ... ? do you write very generic functions (like a delete), with parameters (add extra attributes?), or do you write very specific functions (DRY?). I know in Rails 3 there is a standard set, and everything is unobtrusive there. But how to start in Rails 2.3.5? In short: what are the best practices for doing unobtrusive javascript in rails? :)

  • log4j vs. System.out.println - logger advantages?

    - by wishi_
    Hi! I'm newly using log4j in a project. A fellow programmer told me that using System.out.println is considered bas style and that log4j is something like standard for logging matters nowadays. We do lots of JUnit testing - System.out stuff turns out to be harder to test. Therefore I began utilizing log4j for a Console controller class, that's just handling commandline parameters. // some logger config org.apache.log4j.BasicConfigurator.configure(); Logger logger = LoggerFactory.getLogger(Console.class); Category cat = Category.getRoot(); Seems to work: logger.debug("String"); Produces: 1 [main] DEBUG project.prototype.controller.Console - String I got two questions regarding this: From my basic understanding using this logger should provide me comfortable options to write a logfile with timestamps - instead of spamming the console - if debug mode is enabled at the logger? Why is System.out.println harder to test? I searched stackoverflow and found a testing recipe. So I wonder what kind of advantage I really get by using log4j.

  • Need advice on using Grails and Ajax to append to a div like in Rails

    - by Nate
    I'm just starting out in Grails and need some advice on using Ajax. I want to append some html to the bottom of a div inside a form. This is basically what I have: -form- -div id="listOfchildren"- childrow 1 input fields childrow 2 input fields childrow 3 input fields -/div- -form- -a-Add Child 4-/a- When I click on the "Add Child" I want to make an ajax call that results in a new childrow getting inserted into the "listOfchildren" div. So the document would look like this: -form- -div id="listOfchildren"- childrow 1 input fields childrow 2 input fields childrow 3 input fields childrow 4 input fields -/div- -form- -a-Add Child 5-/a- In Rails I would do something simple like this: render :update do |page| page.insert_html :bottom, "list_of_children", :partial = child_partial page.replace "add_link", :partial = 'add_link' end The previous code sends an javascript back to the browser with two commands. The first command tells the browser to append some html to the bottom of a div. The second command updates the "add link" counter. In grails I can only see how to replace an entire div (which would wipe out the user's existing input) and I don't see how I can call multiple functions from the ajax response. I can probably do this if I was to write some javascript functions in prototype or whatever, but I'd like to avoid that if there is a simpler way. Thanks! Nate

  • Javascript conflict on my html page

    - by tochiro
    Hello, I have an accordion menu and a lightwindow script on my web page. The lightwindow script does not work because of the accordion script because if I delete the latter the lightwindow script works. There must be a conflict but what? Here is the head section of my page: <!-- lightwindow files --> <script type="text/javascript" src="lightwindow/javascript/prototype.js"></script> <script type="text/javascript" src="lightwindow/javascript/scriptaculous.js?load=effects"></script> <script type="text/javascript" src="lightwindow/javascript/lightwindow.js"></script> <link rel="stylesheet" href="lightwindow/css/lightwindow.css" type="text/css" media="screen" /> <!-- accordion scripts --> <script src="js/jquery-1.2.1.min.js" type="text/javascript"></script> <script src="js/menu.js" type="text/javascript"></script> <script src="js/jquery.cookie.js" type="text/javascript"></script> <link rel="stylesheet" type="text/css" href="css/accordion.css" /> Thank you for your time.

  • Are there any radix/patricia/critbit trees for Python?

    - by Andrew Dalke
    I have about 10,000 words used as a set of inverted indices to about 500,000 documents. Both are normalized so the index is a mapping of integers (word id) to a set of integers (ids of documents which contain the word). My prototype uses Python's set as the obvious data type. When I do a search for a document I find the list of N search words and their corresponding N sets. I want to return the set of documents in the intersection of those N sets. Python's "intersect" method is implemented as a pairwise reduction. I think I can do better with a parallel search of sorted sets, so long as the library offers a fast way to get the next entry after i. I've been looking for something like that for some time. Years ago I wrote PyJudy but I no longer maintain it and I know how much work it would take to get it to a stage where I'm comfortable with it again. I would rather use someone else's well-tested code, and I would like one which supports fast serialization/deserialization. I can't find any, or at least not any with Python bindings. There is avltree which does what I want, but since even the pair-wise set merge take longer than I want, I suspect I want to have all my operations done in C/C++. Do you know of any radix/patricia/critbit tree libraries written as C/C++ extensions for Python? Failing that, what is the most appropriate library which I should wrap? The Judy Array site hasn't been updated in 6 years, with 1.0.5 released in May 2007. (Although it does build cleanly so perhaps It Just Works.)

  • Convert function to read from string instead of file in C

    - by Dusty
    I've been tasked with updating a function which currently reads in a configuration file from disk and populates a structure: static int LoadFromFile(FILE *Stream, ConfigStructure *cs) { int tempInt; ... if ( fscanf( Stream, "Version: %d\n",&tempInt) != 1 ) { printf("Unable to read version number\n"); return 0; } cs->Version = tempInt; ... } to one which allows us to bypass writing the configuration to disk and instead pass it directly in memory, roughly equivalent to this: static int LoadFromString(char *Stream, ConfigStructure *cs) A few things to note: The current LoadFromFile function is incredibly dense and complex, reading dozens of versions of the config file in a backward compatible manner, which makes duplication of the overall logic quite a pain. The functions that generate the config file and those that read it originate in totally different parts of the old system and therefore don't share any data structures so I can't pass those directly. I could potentially write a wrapper, but again, it would need to handle any structure passed in in a backwards compatible manner. I'm tempted to just pass the file as is in as a string (as in the prototype above) and convert all the fscanf's to sscanf's but then I have to handle incrementing the pointer along (and potentially dealing with buffer overrun errors) manually. This has to remain in C, so no C++ functionality like streams can help here Am I missing a better option? Is there some way to create a FILE * that actually just points to a location in memory instead of on disk? Any pointers, suggestions or other help is greatly appreciated.

  • onsubmit() does not work.

    - by the Hampster
    Here is something that I find disturbing. I created a small form, and I'm using AJAX to validate for me. I have a javascript function authenticate() that works sometimes. <form method="post" action="" id="login_form" onsubmit="authenticate()";> // various inputs <input type="button" onclick="authenticate()" value="Log In"> </form> authenticate() works just fine when I click the button. However, if I press enter the form is submitted, and it fails. It also fails if I call onSubmit(). In my debugging, I alert the outgoing texts-- they are identical. However, the Prototype Ajax function calls it the onSuccess, but there is just no response from the server. (The server outputs either "Success" or "Failure"). Why the different behaviors for onClick() vs onSubmit()? The exact same function is called, but the results are different. Any help would be appreciated. --Dave

  • Dynamically add User Controls to a Silverlight 4 page

    - by PilotBob
    I am building an iGoogle like "dashboard" for our application with silverlight 4. Each users dashboard (which snapins and their positions) will be stored in the database. Each snap in is a user control, for example... AwesomeSnapin.xaml. On the dashboard page in silverlight I am retrieving the users dashboard which is a collection of snapin objects which include the information on the snapin. I can store the name of the page or the class or whatever is needed. I have the following code which loops through the collection of snapins to add them to the dashboard page. In testing I have just hard coded a single snapin item. Here is the prototype code: foreach (var UserSnapin in op.Entities) { UserControl uc = new AmsiSL.eFinancials.BudgetCheck(); Canvas.SetLeft(uc, UserSnapin.PositionLeft); Canvas.SetTop(uc, UserSnapin.PositionTop); Layout.Children.Add(uc); MessageBox.Show(String.Format("Added {0}",UserSnapin.Snapin.Name)); } The above works fine... but of course adds the BudgetCheck snapin for every item that is defined for the users dashboard. Of course the messagebox is for debugging purposes only. How would I change line 3 of that to load the user control class (using classname or xaml path whichever is better) based on the data in the collection.

  • Help me create a Firefox extension (Javascript XPCOM Component)

    - by Johnny Grass
    I've been looking at different tutorials and I know I'm close but I'm getting lost in implementation details because some of them are a little bit dated and a few things have changed since Firefox 3. I have already written the javascript for the firefox extension, now I need to make it into an XPCOM component. This is the functionality that I need: My Javascript file is simple, I have two functions startServer() and stopServer. I need to run startServer() when the browser starts and stopServer() when firefox quits. Edit: I've updated my code with a working solution (thanks to Neil). The following is in MyExtension/components/myextension.js. Components.utils.import("resource://gre/modules/XPCOMUtils.jsm"); const CI = Components.interfaces, CC = Components.classes, CR = Components.results; // class declaration function MyExtension() {} MyExtension.prototype = { classDescription: "My Firefox Extension", classID: Components.ID("{xxxx-xxxx-xxx-xxxxx}"), contractID: "@example.com/MyExtension;1", QueryInterface: XPCOMUtils.generateQI([CI.nsIObserver]), // add to category manager _xpcom_categories: [{ category: "profile-after-change" }], // start socket server startServer: function () { /* socket initialization code */ }, // stop socket server stopServer: function () { /* stop server */ }, observe: function(aSubject, aTopic, aData) { var obs = CC["@mozilla.org/observer-service;1"].getService(CI.nsIObserverService); switch (aTopic) { case "quit-application": this.stopServer(); obs.removeObserver(this, "quit-application"); break; case "profile-after-change": this.startServer(); obs.addObserver(this, "quit-application", false); break; default: throw Components.Exception("Unknown topic: " + aTopic); } } }; var components = [MyExtension]; function NSGetModule(compMgr, fileSpec) { return XPCOMUtils.generateModule(components); }

  • A function where small changes in input always result in large changes in output

    - by snowlord
    I would like an algorithm for a function that takes n integers and returns one integer. For small changes in the input, the resulting integer should vary greatly. Even though I've taken a number of courses in math, I have not used that knowledge very much and now I need some help... An important property of this function should be that if it is used with coordinate pairs as input and the result is plotted (as a grayscale value for example) on an image, any repeating patterns should only be visible if the image is very big. I have experimented with various algorithms for pseudo-random numbers with little success and finally it struck me that md5 almost meets my criteria, except that it is not for numbers (at least not from what I know). That resulted in something like this Python prototype (for n = 2, it could easily be changed to take a list of integers of course): import hashlib def uniqnum(x, y): return int(hashlib.md5(str(x) + ',' + str(y)).hexdigest()[-6:], 16) But obviously it feels wrong to go over strings when both input and output are integers. What would be a good replacement for this implementation (in pseudo-code, python, or whatever language)?

  • Using "Object.create" instead of "new"

    - by Graham King
    Javascript 1.9.3 / ECMAScript 5 introduces Object.create, which Douglas Crockford amongst others has been advocating for a long time. How do I replace new in the code below with Object.create? var UserA = function(nameParam) { this.id = MY_GLOBAL.nextId(); this.name = nameParam; } UserA.prototype.sayHello = function() { console.log('Hello '+ this.name); } var bob = new UserA('bob'); bob.sayHello(); (Assume MY_GLOBAL.nextId exists). The best I can come up with is: var userB = { init: function(nameParam) { this.id = MY_GLOBAL.nextId(); this.name = nameParam; }, sayHello: function() { console.log('Hello '+ this.name); } }; var bob = Object.create(userB); bob.init('Bob'); bob.sayHello(); There doesn't seem to be any advantage, so I think I'm not getting it. I'm probably being too neo-classical. How should I use Object.create to create user 'bob'?

  • How to get around the jslint error 'Don't make functions within a loop.'

    - by Ernelli
    I am working on making all of our JS code pass through jslint, sometimes with a lot of tweaking with the options to get legacy code pass for now on with the intention to fix it properly later. There is one thing that jslint complains about that I do not have a workround for. That is when using constructs like this, we get the error 'Don't make functions within a loop.' for (prop in newObject) { // Check if we're overwriting an existing function if (typeof newObject[prop] === "function" && typeof _super[prop] === "function" && fnTest.test(newObject[prop])) { prototype[prop] = (function (name, func) { return function () { var result, old_super; old_super = this._super; this._super = _super[name]; result = func.apply(this, arguments); this._super = old_super; return result; }; })(prop, newObject[prop]); } This loop is part of a JS implementation of classical inheritance where classes that extend existing classes retain the super property of the extended class when invoking a member of the extended class. Just to clarify, the implementation above is inspired by this blog post by John Resig. But we also have other instances of functions created within a loop. The only workaround so far is to exclude these JS files from jslint, but we would like to use jslint for code validation and syntax checking as part of our continuous integration and build workflow. Is there a better way to implement functionality like this or is there a way to tweak code like this through jslint?

  • C question: error: expected ')' before '*' token

    - by lhw
    ===EDIT I apologize for not putting the pcb struct into the code snippet. There is a struct called pcb defined in above the two structs I originally posted. Namely, typedef struct{ UINT32 proc; struct pcb *link; }pcb; Hi, I asked a question regarding structs in C a few minutes ago and got an answer blazing fast. But now I'm facing another problem, namely the error in the title of this question. I'm trying to implement a simple priority queue in C using arrays of queues. However, when I try to declare a function on pcb_pQ structure, I get the above error. I have the structs clearly defined in the heard file. In the header file: typedef struct{ pcb *head; pcb *tail; SINT32 size; } pcb_Q; typedef struct pcb_pQ { pcb_Q queues[5]; SINT32 size; } pcb_pQ; Function prototype in header file: /*priority queue operations*/ VOID pcb_pq_enqueue(pcb_pQ*, pcb*); Function impelmentation in .c file: VOID pcb_pq_enqueue(pcb_pQ* pcb_pQ, pcb* pcb) { pcb_Q* pcb_Q_p; int priority; priority = pcb->proc_priority; pcb_Q_p = &pcb_pQ->queues[priority]; pcb_enqueue(pcb_Q_p, pcb); } When I try to compile the above code, I get an "error: expected ')' before '*' token". This error is pointing to the function signature in the .c file, namely VOID pcb_pq_enqueue(pcb_pQ* pcb_pQ, pcb* pcb) { But I am not sure why I am getting this error, could someone give me a hand? Thanks a lot.

  • How does one target all divs of any webpage but differentiate them in javascript?

    - by Chaz
    So I am trying to create an extension in Chrome (a prototype for a project that I am doing) that targets all of the <div> tags of any web page, hides them or rather doesn't display them until the user clicks the mouse (further explained below). So typing a url into the browser yields a white page. The person clicks, and the first <div> appears (probably the mast head or menu). The user clicks again and the second <div> appears. I have gotten to the point where I can hide or show all <div>'s (the obvious easy part) but I am not sure how to go about targeting each since every website has different id's for them while still using the <div> tag. This is what I need the most help with. This is part of a grander operation called the Web Crank. It's just a physical crank that controls the speed by which a web page loads. Each time you make one full rotation of the crank, one section (the first <div>) of the web page loads. The faster you go, the quicker the page loads. I hope this is clear enough. I am a newbie when it comes to this, but I have done some minor coding in the past and it's not such a big deal. Thanks for your help!

  • How to get rid of void-pointers.

    - by Patrick
    I inherited a big application that was originally written in C (but in the mean time a lot of C++ was also added to it). Because of historical reasons, the application contains a lot of void-pointers. Before you start to choke, let me explain why this was done. The application contains many different data structures, but they are stored in 'generic' containers. Nowadays I would use templated STL containers for it, or I would give all data structures a common base class, so that the container can store pointers to the base class, but in the [good?] old C days, the only solution was to cast the struct-pointer to a void-pointer. Additionally, there is a lot of code that works on these void-pointers, and uses very strange C constructions to emulate polymorphism in C. I am now reworking the application, and trying to get rid of the void-pointers. Adding a common base-class to all the data structures isn't that hard (few days of work), but the problem is that the code is full of constructions like shown below. This is an example of how data is stored: void storeData (int datatype, void *data); // function prototype ... Customer *myCustomer = ...; storeData (TYPE_CUSTOMER, myCustomer); This is an example of how data is fetched again: Customer *myCustomer = (Customer *) fetchData (int datatype, char *key); I actually want to replace all the void-pointers with some smart-pointer (reference-counted), but I can't find a trick to automate (or at least) help me to get rid of all the casts to and from void-pointers. Any tips on how to find, replace, or interact in any possible way with these conversions?
