• How can I access and modify objects inside frames with AS3 in a permanent way?

  - by curro

  I have a MovieClip symbol created with flash in a fla file library. There is a textfield in frame one of this movieclip's timeline . There is another frame in the movieclip timeline. There is a custon class definition for this symbol. It is a flipping card in a memory game. I access the textfield by going to frame 2 (gotoAndStop(2)) and setting the textfield's text property ( this.field.text = "hello" ). However if I go to frame 1 and then return to frame 2, the text becomes the original one in the library's symbol. I have to modify the text propery again in a showFace method I've written. Besides, I cannot pass parameters in the constructor because it is a symbol in the library and that would give errors. I find this behaviour of flash extremely weird. Is there a way I can set properties inside frames permanently? Thank you

• Symfony2 & Twig - theming file upload widget

  - by Sacred Socks

  I have an Symfony2 edit form for an entity and one of the fields is for the user's profile picture. I'm trying to theme the Twig file upload widget so that the current picture set for the field is displayed above the file input. So far, I have: {% form_theme edit_form _self %} {% block field_widget %} {% set type = type|default('text') %} {% if type == 'file' %} <img src="{{ value }}" /> {% endif %} {{ block('form_widget_simple') }} {% endblock %} All works well except that the value variable is blank (which makes sense I guess). My question is how can I get hold of the path to the file? Is there a way to pick it out of the form values for the field? Could I perhaps pass it through as an option to the field? Srz if this is a dumb question, still pretty new to Symfony and Twig..

• Javascript Prototyping Question

  - by Nick Lowman

  I'm just reading about Prototypes in JavaScript and Douglas Crockford offers and excellent way to select a new objects prototype but can anyone explain (below) why obj01's type equals 'object' when I pass it in function as it's prototype? if (typeof Object.beget !== 'function') { Object.beget = function (o) { console.log(typeof o);//function var F = function () {}; F.prototype = o; console.log(typeof F);//function return new F(); }; } var func01 = function(){}; var obj01 = Object.beget(func01); console.log(typeof obj01);//object console.log(typeof obj01.prototype);//object I thought it would be console.log(typeof obj01);//function console.log(typeof obj01.prototype);//function

• How to free an Oracle Object-Type passed to an external procedure

  - by chila

  I'm using OTT to pass and load an Object Type from a C++ external procedure. The problem I have is that I don't know how to somehow mark the object for deallocation once extproc has done marshalling it. The object remains in extproc's memory forever making it grow in memory consumtion. Here's part of the code: void decodeFromBuffer(OCIExtProcContext *ctx, GPRS_GPRSCHARGINGRECORD *record, GPRS_GPRSCHARGINGRECORD_ind *recordInd, const unsigned char *buffer, int buffLen, OCIInd *bufferInd) { . . . assert(OCIExtProcGetEnv(ctx, &envh, &svch, &errh) == OCI_SUCCESS); recordInd->_atomic = OCI_IND_NOTNULL; // somehow I should mark the object for deallocation after extproc has done marshalling it // using OCINumberFromInt and OCIStringAssignText to load the object (this memory is never deallocated) . . . } How could I mark the object (and subobjects) for deallocation?

• Checking if parsed date is within a date range

  - by Brett Powell

  So I am using a scripting language with c++-like syntax, and I am trying to think of the best way to check if a date is within range. The problem I am running into is that if the current day is in a new month, the check is failing. Here is what my code looks like: if(iMonth >= iStartMonth && iMonth <= iEndMonth) { if(iDay >= iStartDay && iDay <= iEndDay) { if(iYear >= iStartYear && iYear <= iEndYear) { bEnabled = true; return; When I have something like this: Start date: 3 27 2010 End Date: 4 15 2010 Current Date: 3 31 2010 The day check fails because if (iDay <= iEndDay) does not pass. The scripting language doesn't have a lot of time related functions, and I can't compare timestamps because I'm allowing users to put like "03:27:2010" and "04:15:2010" as start/end dates in a config file. I'm assuming I am just not thinking straight and missing an easy fix.

• What to keep in mind when creating your own custom web services API?

  - by John Conde

  I have created a website which allows users to sign up for, and use, an online service. To help promote the website we will be have resellers who will be offering their own branded services through us. The initial plan is to allow resellers to place registration, login, and lost password forms on their own website and use an API created by us to handle these requests. I have begun outlining how I expect the API to work (and starting documenting it as well) and I want to make sure I get it right, or as close to right, as I can from the beginning as I know once you have declared a public API you want to avoid changing that API at all costs. So far I have decided: To have the user pass their account credentials with each request To require SSL for all requests What else should I be keeping in mind?

• Embedded C++, any tips to avoid a local thats only used to return a value on the stack?

  - by lisarc

  I have a local that's only used for the purposes of checking the result from another function and passing it on if it meets certain criteria. Most of the time, that criteria will never be met. Is there any way I can avoid this "extra" local? I only have about 1MB of storage for my binary, and I have several thousand function calls that follow this pattern. I know it's a minor thing, but if there's a better pattern I'd love to know! SomeDataType myclass::myFunction() { SomeDataType result; // do I really need this local??? // i need to check the result and pass it on if it meets a certain condition result = doSomething(); if ( ! result ) { return result; } // do other things here ... // normal result of processing return SomeDataType(whatever); }

• Why I am not that user after I load cookies?

  - by MoreFreeze

  I want to grab some site data, but it must be a login account. So I register it and login, I found some API about this site that can be used to grab data. I use this Chrome plugin "cookie.txt export" export cookies.txt, I copy all content it export and use following cmd like wget -x --load-cookies cookies.txt http://www.example.com/api/name=xxxx but it doesn't work. It download the page that need I login. So I think this site has some other verification strategy, how can I pass it? Whether I must input in browser manually?

• I'm confused with block in ruby, compared to smalltalk.

  - by weakish

  What does block in ruby mean? It looks similar with smalltalk, but you can't send messages to it. For example, in smalltalk: [:x | x + 3] value: 3 returns 6. But in ruby: {|x| x + 3}.call 3 will cause SyntaxError. Well, you can pass messages to lambda in ruby, though: irb(main):025:0> ->(x){x+3}.call 3 => 6 So in ruby, block is not a block, but lambda is a block? Is this true? I mean, are there any differences between ruby lambda and smalltalk block? If this is true, then what is ruby block?

• Serialize an array of objects as Xxxxs rather than ArrayOfXxxx

  - by Richard

  I'm using ASP.NET MVC with XmlResult from MVCContrib. I have an array of Xxxx objects, which I pass into XmlResult. This gets serialized as: <ArrayOfXxxx> <Xxxx /> <Xxxx /> <ArrayOfXxxx> I would like this to look like: <Xxxxs> <Xxxx /> <Xxxx /> <Xxxxs> Is there a way to specify how a class gets serialized when it is part of array? I'm already using XmlType to change the display name, is there something similar that lets you set its group name when in an array. [XmlType(TypeName="Xxxx")] public class SomeClass Or, will I need to add a wrapper class for this collection?

• How to Communicate between minifb and a GAE-Hosted Silverlight Client

  - by Nick Gotch

  I have a minifb app (technically gminifb) running on Google App Engine with a bunch of handlers for processing all kinds of requests from a Silverlight client. What's the recommended approach for adding the FB GET variables, such as fb_sig, to the HTTP requests? I believe I can technically pass the session key and uid directly and get things to work but it seems there's probably a much better way to do this. I was reading about FBJS AJAX and I'm trying to figure out how I can use it to proxy the HTTP requests from the Silverlight client through it. Is this a good way to do it? And if so, how would I go about doing so? Any other recommendations would be appreciated too. Thanks,

• Change default Console I/O functions handle.

  - by b-gen-jack-o-neill

  Hello. Is it possible to somehow change standart I/O functions handle on Windows? Language preffered is C++. If I understand it right, by selecting console project, compiler just pre-allocate console for you, and operates all standart I/O functions to work with its handle. So, what I want to do is to let one Console app actually write into another app Console buffer. I though that I could get first´s Console handle, than pass it to second app by a file (I don´t know much about interprocess comunication, and this seems easy) and than somehow use for example prinf with the first app handle. Can this be done? I know how to get console handle, but I have no idea how to redirect printf to that handle. Its just study-purpose project to more understand of OS work behind this. I am interested in how printf knows what Console it is assiciated with.

• Is there a linear-time performance guarantee with using an Iterator?

  - by polygenelubricants

  If all that you're doing is a simple one-pass iteration (i.e. only hasNext() and next(), no remove()), are you guaranteed linear time performance and/or amortized constant cost per operation? Is this specified in the Iterator contract anywhere? Are there data structures/Java Collection which cannot be iterated in linear time? java.util.Scanner implements Iterator<String>. A Scanner is hardly a data structure (e.g. remove() makes absolutely no sense). Is this considered a design blunder? Is something like PrimeGenerator implements Iterator<Integer> considered bad design, or is this exactly what Iterator is for? (hasNext() always returns true, next() computes the next number on demand, remove() makes no sense). Similarly, would it have made sense for java.util.Random implements Iterator<Double>?

• jQuery plugin: Validation can't be customized without setting all fields to 'required'?

  - by rasx

  I've spent the day looking at jQuery plugin: Validation by Jörn Zaefferer. I notice that it works fine as long as you call the validate() method without options. In my little squalid world, as soon as I add options, like errorPlacement, I notice that validation ignores form fields that are not marked required. I also notice that many, many demos mark all fields required---or do not pass options. Am I writing about anything familiar here? Or should I astral project to a parallel universe?

• Creating Visual Studio Templates

  - by vanja.

  I'm looking to create a Visual Studio 2008 template that will create a basic project and based on remove certain files/folders based on options the user enters. Right now, I have followed some tutorials online which have let me create the form to query the user and pass the data into an IWizard class, but I don't know what to do from there. The tutorials provide a sample to do some simple substitution: code: Form1 form = new Form1(); DialogResult dlg = form.ShowDialog(); if (dlg == DialogResult.OK) { foreach (KeyValuePair<string, string> pair in form.Parameters) { if (!replacementsDictionary.ContainsKey(pair.Key)) replacementsDictionary.Add(pair.Key, pair.Value); else replacementsDictionary[pair.Key] = pair.Value; } } form.Close(); but I'm looking to selectively include files based on the user settings, and if possible, selectively include code sections in a file based on settings. Is there a clever way to do this, or will I manually have to delete project files in the IWizard:ProjectFinishedGenerating()?

• CLI design and implementation?

  - by Majid

  I am developing a time management tool for my personal use. I prefer using keyboard over mouse, and on the interface have a general purpose text box which will act like a command line. I have just started thinking about what commands I need, what to use for the command names, how to pass in switches and parameters, and so forth. I wonder if some of you have come across a good read along these lines; something that describes the choices you have for designing a cli, and how those affect the complexity of the interpreter, and extendability of the commands. It makes no difference if the descriptions are language-specific or in general terms. However, my implementation will be with javascript. Thank you.

• how to store passwords in database?

  - by rgksugan

  I use jsp and servlets in my web application. i need to store passwords in the database. I found that hashing will be the best way to do that. I used this code to do it. java.security.MessageDigest d = null; d = java.security.MessageDigest.getInstance("SHA-1"); d.reset(); d.update(pass.getBytes("UTF-8")); byte b[] = d.digest(); String tmp = (new BASE64Encoder()).encode(b); When i tried to print the value of tmp, i get some other value.i guess its the hash value of the password. But when i persist this data to the database the original password gets saved there other than the value in tmp.. What is the problem???

• How to send date from one view to another in xcode?

  - by Egor Sosin

  I want to make the program where you have to enter some data, and then it will manipulate that data and show it on the other view when you click done. I search through multiple tutorials, but still cant understand how you do that. I have a textfield - lesson1 and want to pass it to the label in the second view. The views are called EditClasses and DayView. Thanks a lot. Also I need to change the data every 24 hours, what is the best way to do it?

• Is it possible to hide columns in jQuery Grid by default?

  - by Toran Billups

  I have been working with the jQuery Grid the past few days and one thing I have not found any documentation on yet is the ability to hide a column by default. The reason I want this is that I'm building my JSON w/ every property of my object yet my grid might only show 75% of these as valid columns. I want the ability to pass back more JSON than I actually use, and one way I thought to accomplish this would be to hide the columns I'm not using. Any other suggestions are welcome, but I would prefer the ability to push down a larger list of JSON than I actually use by default.

• Does it make a difference in performance if I use self.fooBar instead of fooBar?

  - by mystify

  Note: I know exactly what a property is. This question is about performance. Using self.fooBar for READ access seems a waste of time for me. Unnecessary Objective-C messaging is going on. The getters typically simply pass along the ivar, so as long as it's pretty sure there will be no reasonable getter method written, I think it's perfectly fine to bypass this heavy guy. Objective-C messaging is about 20 times slower than direct calls. So if there is some high-performance-high-frequency code with hundreds of properties in use, maybe it does help a lot to avoid unnessessary objective-c messaging? Or am I wasting my time thinking about this?

• JSObject-like stuff in ActionScript 3?

  - by johncch

  I would like to ask if there is a liveconnect equivalent for ActionScript 3. I understand that there is the ExternalInterface class inside AS3 but it only supports calling a method by name. The really cool thing about Java and LiveConnect is that you can do something like function jsFunc(name) = { this.name = name; this.talk = function(){ alert('hello world my name is ' + this.name); } } javaapplet.function(new jsFunc("bob")); The above approaches pseudo code since I never tested it but I've seen it in action. In AS3, while I am able to pass in an instance of JavaScript "object" into AS, it is often converted into an ActionScript Object instance which does away with all the functions as far as I'm aware. I saw an implementation of JSInterface but I don't think it does specifically that. Is there any way to make OO like javascript work with ActionScript 3?

• fprintf() within a subprogram

• Servlets, long operations

  - by asrijaal

  Hi there, I'm refactoring a big piece of code atm where a long taking operation is executed in a servlet. Now sometimes I don't get a response after the operation has finished. (It has finished because it is printed into the logs) What I wish to achieve would some "fire and forget" behavior by the servlet. I would pass my params to the action and the servlet would immediately return a status (something like: the operation has started, check your logs for further info) Is this possible with servlet 2.5 spec? I think I could get such a behavior with JMS maybe any other solutions out there?
