  • Actionscript 3.0 platformer game

    - by Jez
    I have an flash game with the following code (http://pastie.org/9248528) When I run it, the player just falls and doesn't stop when he hits a platform. I tried debugging it and I had an error with moveCharacter's timer, but I don't know if that is the main problem. I put the player inside the wall and debugged it using breakpoints and it didn't detect that the player was inside the wall, skipping moving it to outside of the wall. If anyone has any ideas on what is wrong with my code then that would be great thanks!

  • Where can I find "reference barcodes" to verify barcode library output?

    - by mjustin
    This question is not about 'best' barcode library recommendation, we use various products on different platforms, and need a simple way to verify if a given barcode is correct (according to its specification). There are some free online bar code generators in the Internet, and I found many differences between their output and our library output regarding graphics and text field below the code. Now I am not sure which one is wrong, and before filing bug report I want to make sure how the correct barcode should look like. We mainly need Code128 and UCC/EAN-128 with A/B/C subcodes. Which resource would you suggest?

  • Get property name from class

    - by Polaris
    I need property name in my app and I use next code to get it string PropertyName =SomeClass.GetType().GetProperty("Category").Name; But I think that is bad idea. Because I use web service classes and I dont know when property names can be changed. This code give me exception only in runtime. But if I write something like this SomeClassInstance.Property.GetProperyName i get exception in moment of compilation and repair this problem. Is it possible to get property name dynamically?

  • How can I catch a change event from an HTML text field when a user clicks on a link after editing?

    - by Eric the Red
    Our webapp has a form with fields and values that change depending on values entered. Each time there is a change event on one of the form elements, we use an expensive AJAX call to update other elements on the page. This works great for selects, radio buttons and checkboxes. The issue comes in when a user adds content to a text field, and then clicks a link without taking the focus from the text field. The browser moves to a new page, and the contents of the text field are never saved. Is there an easy way to code around this? The AJAX call is too expensive to call with each key press. Here's an example of my Prototype code at the moment: $$('.productOption input.text').invoke('observe', 'change', saveChangeEvent);

  • How can I do these operations in C?

    - by Juan Antonio
    Hello, I'm converting some assembly code to C to be able to use it with the current compiler environment I have to work with. I've reached 2 operations I don't know how to translate to C. Anyone know how to do it? In both, offset is an unsigned 32-bit integer and shift is a signed integer value. C_FLAG is a bool. OP1: __asm { __asm mov ecx, shift __asm ror offset, cl } OP2: __asm { __asm bt dword ptr C_FLAG, 0 __asm rcr offset, 1 } Thank you very much for your expertise. P.S.: I'm not the original developer, nor I have seen many x86 assembly code...

  • AJAX form sections - how to pass url of next stage of form

    - by dan727
    Hi, I've got a multi-part form (in a PHP MVC setup) which I have working correctly without javascript enhancement. I'm starting to add the AJAX form handling code which will handle each stage of a form submission, validating/saving data etc, before using AJAX to load the next stage of the form. I'm wondering how best to pass the URL of the next stage to the current form being processed, so that my jQuery form handling code can process the current form, then load the next part via AJAX. The form "action" is different from what the url of the next stage of the form is - what do you think would be good practice here? I was thinking about either appending the url of the next stage to the form action url, via a query string - then just use javascript to extract this url when the form is successfully processed. The other option is via a hidden form element. Not sure what other client side options I have here Any thoughts?

  • Why does the Scala compiler disallow overloaded methods with default arguments?

    - by soc
    While there might be valid cases where such method overloadings could become ambiguous, why does the compiler disallow code which is neither ambiguous at compile time nor at run time? Example: // This fails: def foo(a: String)(b: Int = 42) = a + b def foo(a: Int) (b: Int = 42) = a + b // This fails, too. Even if there is no position in the argument list, // where the types are the same. def foo(a: Int) (b: Int = 42) = a + b def foo(a: String)(b: String = "Foo") = a + b // This is OK: def foo(a: String)(b: Int) = a + b def foo(a: Int) (b: Int = 42) = a + b // Even this is OK. def foo(a: Int)(b: Int) = a + b def foo(a: Int)(b: String = "Foo") = a + b val bar = foo(42)_ // This complains obviously ... Are there any reasons why these restrictions can't be loosened a bit? Especially when converting heavily overloaded Java code to Scala default arguments are a very important and it isn't nice to find out after replacing plenty of Java methods by one Scala methods that the spec/compiler imposes arbitrary restrictions.

  • Why are there two implementations of std::sort (with and without a comparator) rather than one implementation with a default template parameter?

    - by PolyVox
    In my code I'm adopting a design strategy which is similar to some standard library algorithms in that the exact behavior can be customized by a function object. The simplest example is std::sort, where a function object can control how the comparison is made between objects. I notice that the Visual C++ provides two implementations of std::sort, which naturally involves code duplication. I would have imagined that it was instead possible to have only one implementation, and provide a default comparator (using operator< ) as a default template parameter. What is the rational behind two separate versions? Would my suggestion make the interface more complex in some way? Or result in confusing error messages when the object does not provide operator Thanks, David

  • Drag and drop game - why isn't it working now I've moved it to another domain?

    - by vward
    Earlier this year I did some work on a drag and drop game. It was the first thing I'd coded other than basic html. I got it working but then had to put it to one side for a while. I've now come back to work on it. The game I had created was put on the ftp of a domain I no longer have. I took the html and image files and put them on another domain expecting them to work. However now nothing drags! I don't know what could be different. I can barely remember how I coded this in the first place. Is there an additional file that should be on the ftp or something like that? Can anyone shed any light?

  • How to retrieve the location of a control on the view?

    - by amok
    I have a button on a view, I want to add another button next to it when the first button is touched. Therefore I need it's top left corner to do the math. Here's what is puzzling me greatly: // this code is executed when the button is pressed NSLog(@"X:%f",moreButton.frame.origin.x); that returns on the first and second click the followings: 2010-04-24 22:58:25.883 iPad PopOver[8095:40b] X:-1.999002 2010-04-24 22:58:25.884 iPad PopOver[8095:40b] Y:0.000000 why and how can I get the x,y of an existing button on the view? (button created via IB) Thanks! mE ps: I have looked at similar posts and my code looks fine but I keep getting zeros (it's an ipad app if matters in any way)

  • How can I (is there a way to) convert an HRESULT into a system specific error message?

    - by Billy ONeal
    According to this, there's no way to convert a HRESULT error code into a Win32 error code. Therefore (at least to my understanding), my use of FormatMessage in order to generate error messages (i.e. std::wstring Exception::GetWideMessage() const { using std::tr1::shared_ptr; shared_ptr<void> buff; LPWSTR buffPtr; DWORD bufferLength = FormatMessageW( FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_IGNORE_INSERTS, NULL, GetErrorCode(), 0, reinterpret_cast<LPWSTR>(&buffPtr), 0, NULL); buff.reset(buffPtr, LocalFreeHelper()); return std::wstring(buffPtr, bufferLength); } ) does not work for HRESULTs. How do I generate these kinds of system-specific error strings for HRESULTs?

  • Factory vs instance constructors

    - by Neil N
    I can't think of any reasons why one is better than the other. Compare these two implementations: public class MyClass { public myClass(string fileName) { // some code... } } as opposed to: public class MyClass { private myClass(){} public static Create(string fileName) { // some code... } } There are some places in the .Net framework that use the static method to create instances. At first I was thinking, it registers it's instances to keep track of them, but regular constructors could do the same thing through the use of private static variables. What is the reasoning behind this style?

  • c++ normalizing data sizes across systems

    - by Bocochoco
    I have a struct with three variables: two unsigned ints and an unsigned char. From my understanding, a c++ char is always 1 byte regardless of what operating system it is on. The same can't be said for other datatypes. I am looking for a way to normalize POD's so that when saved into a binary file, the resulting file is readable on any operating system that the code is compiled for. I changed my struct to use a 1-byte alignment by adding #pragma as follows: #pragma pack(push, 1) struct test { int a; } #pragma pack(pop) but that doesn't necessarily mean that int a is exactly 4 bytes on every os, I don't think? Is there a way to ensure that a file saved from my code will always be readable?

  • Execute PHP after new Order in Magento

    - by Israel Lopez
    Hello There, I'm trying to figure out where I could drop in some PHP code to notify a CRM we are using (Solve360) that a new order has been placed, and that an event should be created (API) to fulfill the order. Order Product Checkout Complete Checkout & Capture CC Side notify CRM Done Not sure where to start, but I have had to make some small tweaks to fix the Quantum Gateway payment processor to work. In that module it appears that the objects for the order (email, amt, details) were available. However it seems it would be quite 'dirty' to insert more PHP code in there. Ideas? PHP 5.2.x & Magento 1.4.x

  • Facebook Error: "The client token cannot be used for this API" - works on DEV and STAGE but not on LIVE app?

    - by Studio Temp
    I've built a notification sending system that sends notifications to all users of our app, using the app access token. This system is currently running on my localhost. When I configure it with the appid and appsecret for my dev and stage environments, it works fine. But when I put in the appid and appsecret of the LIVE app, I get this error: {"message":"The client token cannot be used for this API", "type":"OAuthException", "code":190} So what's different between dev and live? Dev and Stage are in sandbox mode, Live is not. So I tried disabling sandbox mode on Dev/Stage and they continue to function fine. Dev works fine, Stage works fine, Live gives this error. All other code is the same except for the appid, appsecret, and redirect_uri (changing it to match the domain of each environment). I have checked this post, but unfortunately resetting our appsecret on a site with 1,000,000 users is not something we can do at the moment (too much other functionality relies on it).

  • Is the scope of what Xcode's "Build and Analyze" will catch as a leak supposed to be this limited?

    - by Ranking Stackingblocks
    It doesn't care about this: NSString* leaker() { return [[NSString alloc] init]; } I thought it would have been smart enough to check if any code paths could call that function without releasing its return value (I wouldn't normally code this way, I'm just testing the analyzer). It reports this as a leak: NSString* leaker() { NSString* s = [[NSString alloc] init]; [s retain]; return s; } but NOT this: NSString* leaker() { NSString* s = [[NSString alloc] init]; // [s retain]; return s; } which seems particularly weak to me. Does it only analyze within the local scope? If the tool can't pick up on things like this, how can I expect it to pick up on actual mistakes that I might make?

Thanks :) Its also defiantly at least connecting to the website as my firewall asked me if the Terminal was aloud to access it. At the moment not only is it displaying no errors its actually letting anything through and saving it.
