• PHP __call vs method_exists

  - by neo

  The Project I'm working on contains something like a wrapper for call_user_func(_array) which does some checks before execution. One of those checks is method_exists (In Case the supplied first argument is an instance of a class and the second is a method name) The other is_callable. The function will throw an exception if one of those checks fails. My Code contains an array with function names (setFoo, setBar, etc.) and the php magic function for overloading (__call) which handles setting, replacing and deletion of certain variables (better certain array elements). The Problem: method_exists will return false if the function is not defined. Do I have any chance to get a true if the __call function does proper handling of the request?

• How to hide URL from users when submitting this form?

  - by Camran

  I have a form with many many fields... When submitting these fields, I use the POST method which hides the actual variables passed along to the PHP page. However, I can't get rid of the complete link. Changing from GET to POST did make all the form fields invisible in the URL, but this part is still visible: mydomain.com/bin/query# I want it to be invisible, or say: mydomain.com/search I have mod_rewrite enabled so there is a possibility to do this with mod_rewrite I think, but I am new to mod_rewrite so I need your help... How should I hide this URL? If you need more input let me know...

• How do you pass objects between View Controllers in Objective-C?

  - by editor

  I've been trudging through some code for two days trying to figure out why I couldn't fetch a global NSMutableArray variable I declared in the .h and implemented in .m and set in a the viewDidLoad function. It finally dawned on me: there's no such thing as a global variable in Objective-C, at least not in the PHP sense I've come to know. I didn't ever really read the XCode error warnings, but there it was, even if not quite plain English: "Instance variable 'blah' accessed in class method." My question: What am I supposed to do now? I've got two View Controllers that need to access a central NSMutableDictionary I generate from a JSON file via URL. It's basically an extended menu for all my Table View drill downs, and I'd like to have couple other "global" (non-static) variables. Do I have to grab the JSON each time I want to generate this NSMutableDictionary or is there some way to set it once and access it from various classes via #import? Do I have to write data to a file, or is there another way people usually do this?

• Android Java Eclipse Intent with 2 Projects

  - by user3793685

  Good day! I have 2 Projects in my Eclipse. MainActivity1 and MainActivity2 are the names of the activities. The MainActivity2 is connected to the MainActivity1 via Project in the properties of the MainActivity1. So far, I can call the package of the MainActivity2 from the MainActivity1. Now, below are my problem: I have a button in MainActivity1. What I want to do is after I click on the button in the MainActivity1, it runs the MainActivity2 project and some variables will be passed on to the MainActivity2. I've been searching in google for a while now and I couldn't get the right keyword for it. I've checked some of the questions here in StackOverflow but I'm unable to locate the problem similar to mine with calling and running the MainActivity2 class from the MainActivity1.java I'm a noob in Android Java but have knowledge in other OOP. Any tips will be a great help. Thanks

• Can we avoid multiple if''s?

  - by Newbie

  I tried my level best to write an improved version but failed. inFiles.ToList().ForEach(i => { filePath = inFolder + "\\" + i.Value; if (i.Key.Equals(replacementFile)) { replacementCollection = GetReplacementDataFromFile(filePath); } else if (i.Key.Equals(standardizationFile)) { standardizationCollection = GetStandardizationDataFromFile(filePath); } }); The problem is that I cannot use a switch case over here because the comparison variables are not constant. Kindly help to improve this code. I am using C#(3.0). Thanks

• AJAX with jQuery not returning data

  - by James P

  This is my Javascript: $(document).ready(function() { $('#like').bind('keydown', function(e) { if(e.keyCode == 13) { var likeMsg = $('#like').val(); if(likeMsg) { // Send the AJAX request to like.php $.ajax({ url: 'like.php', success: function(data) { alert('Content: ' + data); } }); } } }); }); And this is my like.php file: <?php echo "It works! :)"; ?> When I press enter on the #like input, it seems the AJAX request is sent and an alert box comes up saying: Content:, but there's no data being sent back from like.php... I have checked if the file exists and if it's in the same directory and whatever and it is, so I'm pretty much clueless atm. Does anyone know what could be wrong here? Cheers.

• Beginning Programmer Interested in Android - Should I Start with Java?

  - by Hudey

  I'm a beginner in programming. My experience so far is only in Actionscript 2 and 3. So I have a basic understanding of declaring variables, loops, arrays, if/then, do/while... I'm wanting to move to developing for Android phones so I'm wondering what suggestions people have for where to go next. Should I jump right to Android? Start with a 'beginning Java' approach? Or should I go some other route to beef up my knowledge of OOP concepts before launching into Android? I have my Dev environment set up and completed the Hello Android tutorial and I'm just wondering if I am going to be in over my head quickly?

• Dynamically choosing css property in animation

  - by paddywhack

  Hi, It seems a straightforward thing but I'm not having much success. I'm just implementing a simple animation moving a div left or up using animate() but I would like to be able to set the "top" and "left" css properties dynamically. I would like to use the same function rather than have to have two, one for "left" and one for "top". Here's some code which gives the idea. function test($element){ $element.click(function(){ var cssProperty; var direction = "left"; var moveTo = "100px"; if (direction === "top") { cssProperty = "top"; } else { cssProperty = "left"; } /*Using variable as CSS property - This doesn't work */ $(this).animate({ cssProperty: moveTo }, 1000); /*Using variable as the CSS Values - This does */ $(this).animate({ left: moveTo }, 1000); }); } Variables works on the css value side but not on the css selector side. Anyone have any suggestions? Thanks

• (WinForm/.net) Databind List Of Classes To A DataGridView. But Not Show Certain Public Properties

  - by Pyronaut

  I'm not even sure if i'm doing this correctly. But basically I have a list of objects that are built out of a class. From there, I am binding the list to a datagrid view that is on a Windows Form (C#) From there, it shows all the public properties of the object, in the datagrid view. However there is some properties that i still need accessible from other parts of my application, but aren't really required to be visible in the DataGridView. So is there an attribute or something similar that I can write above the property to exclude it from being shown. P.S. Im binding at runtime. So i cannot edit the columns via the designer. P.P.S. Please no answers of just making public variables (Although if that is the only way, let me know :)).

• link_to_remote and jquery accordion

  - by badnaam

  I have a standard jquery ui accordion and I load content into it using a link_to_remote tag (in the accordion header). All this works fine. The problem is, once the content is loaded, I dont want a ajax call, I just want the accordion to fold, like it should normally do. I tried doing this using the following jquery but clicking the header hence the link still makes a request. #lbs_list is the div inside the accordion. $j('#lnk_show_benefit').bind('click', function(e) { if ($j('#lbs_list').is(':visible')) { e.preventDefault(); return false; } else { return true; } });

• WPF/Silverlight DataBinding to interface property (with hidden implementation)

  - by Dave

  I have the following (C#) code namespace A { interface IX { bool Prop { get; set; } } class X : IX { public bool Prop { ... } } // hidden implementation of IX } namespace B { .. A.IX x = ...; object.DataContext = x; object.SetBinding(SomeDependencyProperty, new Binding("Prop")); .. } So I have a hidden implementation of an interface with a property "Prop" and I need to bind to this property in code. My problem is that the binding isn't working unless I make class X public. Is there any way around this problem?

• Rendering HTML in rails without actually displaying it

  - by Kevin Whitaker

  Hello all, My current project requires me to assemble a .zip file containing HTML and text-only templates for a user to download, for importing into an email marketing program. I've inherited this project, and currently the code uses a "fake" model (that is a model that does not directly correlate to a database table), in which it stores the entire template in a string, using dynamic variables to populate certain areas. The "fake" model then has a method for creating a zip file. It seems to me that there has to be a better way to do this. I was wondering if there was a way to move the template into a .erb/haml file, and then write a method that would populate the file in preparation for being zipped up? Basically, is there a way to render an HTML and text file, without actually having to display them? Thanks for any help.

• Perl regular expression question

  - by user368311

  Suppose I have variables $x1 = 'XX a b XX c d XX'; $x2 = 'XX a b XX c d XX e f XX'; I want a regular expression that will find each instance of letters between XX. I'm looking for a general solution, because I don't know how many XX's there are. I tried using /XX(.*?)XX/g but this only matches "a b" for x1 and "a b", "e f" for x2 because once the first match is found, the engine has already read the second "XX". Thanks for any help.

• jQuery Animation and Classes

  - by ehdv

  Assume you have a list item, <li id="foo"> which you want to fade from one color to another when moused over, and that you are using jQuery. This is fairly easy: $('li#foo').bind('mouseenter' , function(e) { $(this).animate({backgroundColor: '#F00'} , 300); }); However, what if you wanted to get the resulting color or other style rules from a class defined in CSS without also declaring them in JavaScript? It seems there's no way to learn style information from CSS rules without having an example of the rule already in the document, which would require you to animate the <li> to the target appearance, then in the animation-finished callback, set the class which leads to redundant style declarations and can foul up your CSS at "runtime". Sorry if this question's unclear: It doesn't occur in the context of any specific project, I'm just curious how you'd go about this. Also, I know CSS3 hypothetically includes support for such transitions but using CSS for dynamic behavior like this seems such an ugly hack.

• Problem with NSMutableArray?

  - by RRB

  Hi, i initialize instance variables in .h file, NSInteger saveValue0, saveValue1, saveValue2, saveValue3; NSMutableArray *nodeArray; Now in .m file, in viewWillAppear event, saveValue0 = 0; saveValue1 = 2; saveValue2 = 3; saveValue3 = 0; nodeArray = [[NSMutableArray alloc] initWithObjects:saveValue0, saveValue1, saveValue2, saveValue3, nil]; But above variable does not inserted in the array. When i trying to see the objects in array using break point, it gives me 0 objects present in nodeArray. Why it will give me 0 objects. Any reason behind that?

• javascript var declaration within loop

  - by Trouts

  hello, /*Test scope problem*/ for(var i=1; i<3; i++){ //declare variables var no = i; //verify no alert('setting '+no); //timeout to recheck setTimeout(function(){ alert('test '+no); }, 500); } it alerts "setting 1" and "setting 2" as expected, but after the timeout it outputs "test 2" twice - for some reason the variable "no" is not reset after the first loop... i've found only an "ugly" workaround... /*Test scope problem*/ var func=function(no){ //verify no alert('setting '+no); //timeout to recheck setTimeout(function(){ alert('test '+no); }, 500); } for(var i=1; i<3; i++){ func(i); } Any ideas on how to workaround this problem in a more direct way? or is this the only way?

• [C++] Start a thread using a method pointer

  - by Michael

  Hi ! I'm trying to develop a thread abstraction (POSIX thread and thread from the Windows API), and I would very much like it to be able to start them with a method pointer, and not a function pointer. What I would like to do is an abstraction of thread being a class with a pure virtual method "runThread", which would be implanted in the future threaded class. I don't know yet about the Windows thread, but to start a POSIX thread, you need a function pointer, and not a method pointer. And I can't manage to find a way to associate a method with an instance so it could work as a function. I probably just can't find the keywords (and I've been searching a lot), I think it's pretty much what Boost::Bind() does, so it must exist. Can you help me ?

• MySql paging; "Showing result-set" of "total found" help

  - by Camran

  I need a formula for showing results on my classifieds website. I am now done with the paging of records, but this formula for showing results remains. I want it like this: Showing 1-50 of 123 found. Now what is the formula for this? I have these variables which should be enough I think: $results_per_page = 50; //results per page $page = 1; //current page Also a variable called $num_total contains the total nr of hits, in this case 123. Thanks

• C++ string how to

  - by typoknig

  This is a very simple question and I feel stupid for asking it, but I am pressed for time and I need to figure it out :) I just need to know how to make a string that contains text and other variables. For instance in Java I can just do this: String someString; for(int i = 0; i>10; i++){ someString = ("this text has printed " + i + " times"); //how do I create this line in C++? System.out.println(someString); i++; }

• Objects with inheritance memory storage

  - by nikitas350

  Say that i have some classes like this example. class A { int k, m; public: A(int a, int b) { k = a; m = b; } }; class B { int k, m; public: B() { k = 2; m = 3; } }; class C : private A, private B { int k, m; public: C(int a, int b) : A(a, b) { k = b; m = a; } }; Now, in a class C object, are the variables stored in a specific way? I know what happens in a POD object, but this is not a POD object...

• How to manage member variable in C++

  - by rhapsodyn

  In brief, my question is about member variables as pointers in unmanaged C++. In java or c#, we have "advanced pointer". In fact, we can't aware the "pointer" in them. We usually initialize the member of a class like this: member = new Member(); or member = null; But in c++, it becomes more confusing. I have seen many styles: using new, or leave the member variable in stack. In my point of view, using boost::shared_ptr seems friendly, but in boost itself source code there are news everywhere. It's the matter of efficiency,isn't it? Is there a guildline like "try your best to avoid new" or something?

• Loading multiple embedded flash apps onto an HTML page- problem with ordering

  - by shudson250

  We need to load an embedded version of a site written in Flash, and not originally designed to load multiple instances of itself, on a HTML page. The specific issue is how to get them to load in order when embedded, given that they are all being opened by the same instance of the flash player. It's a complicated mapping application, and at the moment, the maps and data get intermixed as the session variables are overwritten by another instance starting to load before the previous one has finished. We need a way to have them load sequentially, one finishing before another starts to load. The most we can specify in the URL is an &order=1 or similar. We have PHP and SQL on the backend. Edit: The embedded versions are being loaded in an iFrame of a parent site. One php file loads one swf, as many times as the parent site desires.

• Best place to create windows form objects

  - by user333484

  I'm creating a windows app in c# 2008 that will have around 8-10 dialog boxes. I want these forms to exist throughout the life of the program. Where's the best place to create and store the objects? I'm coming from Delphi, where Form objects were usually stored in global variables. I'm tempted to do it in the static Program class. Should I put them in the main form instead? Thanks for helping a C# newb out.
