  • CakePHP passing parameters to action

    - by iancocco
    Hi im kinda new in cakephp and having a lot of trouble adjusting.. Here's my biggest problem .. Im trying to pass a parameter to an action, it does load, but when my script goes from the controller to the view, and goes back to the controller again, its gone. CONTROLLER CODE function add($mac = 0) { if(isset($this->params['form']['medico'])) { $temp= $this->Person->find('first', array('conditions' => array('smartphones_MAC' => $mac))); $id= $temp['Person']['id']; $this->Union->set('events_id', $id+1); $this->Union->set('people_id', $id); $this->Union->save(); } VIEW CODE (This is a menu, i only have one button right now) <fieldset> <legend>SELECCIONE SU ALERTA</legend> <?php echo $form->create('Event'); echo $form->submit('EMERGENCIA MEDICA',array('name'=>'medico')); echo $form->end(); ?> </fieldset>

  • Linq-to-sql Add item and a one-to-many record at once

    - by Oskar Kjellin
    I have a function where I can add articles and users can comment on them. This is done with a one to many relationship like= "commentId=>ArticleId". However when I try to add the comment to the database at the same time as I add the one to many record, the commentId is not known. Like this code: Comment comment = new Comment(); comment.Date = DateTime.UtcNow; comment.Text = text; comment.UserId = userId; db.Comments.InsertOnSubmit(comment); comment.Articles.Add(new CommentsForArticle() { ArticleId = articleId, CommentId = comment.CommentId }); The commentId will be 0 before i press submit. Is there any way arround not having to submit in between or do I simply have to cut out the part where I have a one-to-many relationship and just use a CommentTable with a column like "ArticleId". What is best in a performance perspective? I understand the underlying issue, I just want to know which solution works best.

  • What Scheme Does Ghuloum Use?

    - by Don Wakefield
    I'm trying to work my way through Compilers: Backend to Frontend (and Back to Front Again) by Abdulaziz Ghuloum. It seems abbreviated from what one would expect in a full course/seminar, so I'm trying to fill in the pieces myself. For instance, I have tried to use his testing framework in the R5RS flavor of DrScheme, but it doesn't seem to like the macro stuff: src/ghuloum/tests/tests-driver.scm:6:4: read: illegal use of open square bracket I've read his intro paper on the course, An Incremental Approach to Compiler Construction, which gives a great overview of the techniques used, and mentions a couple of Schemes with features one might want to implement for 'extra credit', but he doesn't mention the Scheme he uses in the course. Update I'm still digging into the original question (investigating options such as Petit Scheme suggested by Eli below), but found an interesting link relating to Gholoum's work, so I am including it here. [Ikarus Scheme](http://en.wikipedia.org/wiki/Ikarus_(Scheme_implementation)) is the actual implementation of Ghuloum's ideas, and appears to have been part of his Ph.D. work. It's supposed to be one of the first implementations of R6RS. I'm trying to install Ikarus now, but the configure script doesn't want to recognize my system's install of libgmp.so, so my problems are still unresolved. Example The following example seems to work in PLT 2.4.2 running in DrEd using the Pretty Big (require lang/plt-pretty-big) (load "/Users/donaldwakefield/ghuloum/tests/tests-driver.scm") (load "/Users/donaldwakefield/ghuloum/tests/tests-1.1-req.scm") (define (emit-program x) (unless (integer? x) (error "---")) (emit " .text") (emit " .globl scheme_entry") (emit " .type scheme_entry, @function") (emit "scheme_entry:") (emit " movl $~s, %eax" x) (emit " ret") ) Attempting to replace the require directive with #lang scheme results in the error message foo.scm:7:3: expand: unbound identifier in module in: emit which appears to be due to a failure to load tests-driver.scm. Attempting to use #lang r6rs disables the REPL, which I'd really like to use, so I'm going to try to continue with Pretty Big. My thanks to Eli Barzilay for his patient help.

  • Facebook og:url ignored in favour of a Facebook hosted page about the og entity

    - by Dan
    I am trying to implement the Like button on my pages. Those pages represent the review page for a product. When a user Likes the page, it shows up in Facebook (not as a link, but as liking an entity), however when you click on the entity in Facebook it links through to a facebook.com hosted page representing the page. I want the user to be redirected to the og:url page? This happens for example when you Like an artist page on Grroveshar: http://grooveshark.com/#!/artist/Elbow/4795 I am clearly "doing it wrong". I am using the following markup to include the SDK. MYAPPID is included by the code generator Facebook provides so I assume it is required. <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&appId=MYAPPID"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> Then my code to render the Like button. <div class="fb-like" data-send="false" data-width="450" data-show-faces="true"></div> And finally my og tags: <meta property="og:title" content="My product" /> <meta property="og:type" content="product" /> <meta property="og:url" content="http://site.com/product_1/" /> <meta property="og:image" content="http://site.com/image1.jpg" /> <meta property="og:site_name" content="My-Site-Name.com" /> <meta property="fb:admins" content="MYFACEBOOKID" /> <meta property="fb:app_id" content="MYAPPID" /> Thanks!

  • How do I animate UserControl objects using Storyboard and DoubleAnimation?

    - by Neo
    In my WPF application, I have a Canvas object that contains some UserControl objects. I wish to animate the UserControl objects within the Canvas using DoubleAnimation so that they go from the right of the Canvas to the left of the Canvas. This is how I have done it so far (by passing the UserControl objects into the function): private void Animate(FrameworkElement e) { DoubleAnimation ani = new DoubleAnimation() { From = _container.ActualWidth, To = 0.0, Duration = new Duration(new TimeSpan(0, 0, 10), TargetElement = e }; TranslateTransform trans = new TranslateTransform(); e.RenderTransform = trans; trans.BeginAnimation(TranslateTransform.XProperty, ani, HandoffBehavior.Compose); } However, this doesn't allow me to pause the animation, so I have considered using a Storyboard instead to do this, but I'm not sure how to implement this. This has been my attempt so far: private void Animate(FrameworkElement e) { DoubleAnimation ani = new DoubleAnimation() { From = _container.ActualWidth, To = 0.0, Duration = new Duration(new TimeSpan(0, 0, 10), TargetElement = e }; Storyboard stb = new Storyboard(); Storyboard.SetTarget(ani, e); Storyboard.SetTargetProperty(ani, "Left"); stb.Children.Add(ani); stb.Begin(); } Of course, this fails as UserControl doesn't have a Left property. How can I achieve what I'm after? Thanks.

  • Catching a nested-in-template exception [C++]

    - by Karol
    Hello, I have a problem with writing a catch clause for an exception that is a class nested in a template. To be more specific, I have a following definition of the template and exception: /** Generic stack implementation. Accepts std::list, std::deque and std::vector as inner container. */ template < typename T, template < typename Element, typename = std::allocator<Element> > class Container = std::deque > class stack { public: class StackEmptyException { }; ... /** Returns value from the top of the stack. Throws StackEmptyException when the stack is empty. */ T top() const; ... } I have a following template method that I want exception to catch: template <typename Stack> void testTopThrowsStackEmptyExceptionOnEmptyStack() { Stack stack; std::cout << "Testing top throws StackEmptyException on empty stack..."; try { stack.top(); } catch (Stack::StackEmptyException) { // as expected. } std::cout << "success." << std::endl; } When I compile it (-Wall, -pedantic) I get the following error: In function ‘void testTopThrowsStackEmptyExceptionOnEmptyStack()’: error: expected type-specifier error: expected unqualified-id before ‘)’ token === Build finished: 2 errors, 0 warnings === Thanks in advance for any help! What is interesting, if the stack implementation was not a template, then the compiler would accept the code as it is.

  • Cannot read values from [NSUserDefaults standardUserDefaults] after synchronize

    - by Nonlinearsound
    In the Application Delegate didFinishLaunching method, I am using the following code to build up a new NSDictionary to be used as the new settings bundle for the user: NSNumber *testValue = (NSNumber*)[[NSUserDefaults standardUserDefaults] objectForKey:@"settingsversion"]; if (testValue == nil) { NSNumber *numNewDB = [NSNumber numberWithBool:NO]; NSNumber *numFirstUse = [NSNumber numberWithBool:YES]; NSDate *dateLastStatic = [NSDate date]; NSDate *dateLastMobile = [NSDate date]; NSNumber *numSettingsversion = [NSNumber numberWithFloat:1.0]; NSDictionary *appDefaults = [NSDictionary dictionaryWithObjectsAndKeys: numNewDB, @"newdb", numFirstUse, @"firstuse", numSettingsversion, @"settingsversion", dateLastStatic, @"laststaticupdate", dateLastMobile, @"lastmobileupdate", nil]; [[NSUserDefaults standardUserDefaults] registerDefaults:appDefaults]; [[NSUserDefaults standardUserDefaults] synchronize]; } Later in another ViewController I am trying to read back a value from that same Dictionary, saved as the NSUserDefaults - well at least I thought it would, but I don't get any valid object pointer for the desired member lastUpdate back there: in .h file: NSDate *lastUpdate; in the .m file in a member function: lastUpdate = (NSDate *)[[NSUserDefaults standardUserDefaults] objectForKey:@"laststaticupdate"]; Even, if I print out the content of [NSUserDefaults standardUserDefaults] I only get this: 2010-04-29 15:13:22.322 myApp[4136:207] Content of UserDefaults: <NSUserDefaults: 0x11d340> This leads me to the conclusion that there is no standardUserDefaults dictionary somewhere in memory or it cannot be determined as such a structure. Edit: Every time, I restart the app ión the device, the check for testValue is Nil and I am building up the dictionary again but after one run it should be persistent on the Phone, right? Am I doing something wrong somewhere in between? I have the feeling that I yet didn't really understand how to load and save settings persistent for a certain application on the iPhone. Is there anything I have to do additionally to this? Integrating a settings.bundle in XCode or saving the dictionary manually to the Documents folder? Can someone help me out here? Thanks a lot!

  • Why did this work with Visual C++, but not with gcc?

    - by Carlos Nunez
    I've been working on a senior project for the last several months now, and a major sticking point in our team's development process has been dealing wtih rifts between Visual-C++ and gcc. (Yes, I know we all should have had the same development environment.) Things are about finished up at this point, but I ran into a moderate bug just today that had me wondering whether Visual-C++ is easier on newbies (like me) by design. In one of my headers, there is a function that relies on strtok to chop up a string, do some comparisons and return a string with a similar format. It works a little something like the following: int main() { string a, b, c; //Do stuff with a and b. c = get_string(a,b); } string get_string(string a, string b) { const char * a_ch, b_ch; a_ch = strtok(a.c_str(),","); b_ch = strtok(b.c_str(),","); } strtok is infamous for being great at tokenizing, but equally great at destroying the original string to be tokenized. Thus, when I compiled this with gcc and tried to do anything with a or b, I got unexpected behavior, since the separator used was completely removed in the string. Here's an example in case I'm unclear; if I set a = "Jim,Bob,Mary" and b="Grace,Soo,Hyun", they would be defined as a="JimBobMary" and b="GraceSooHyun" instead of staying the same like I wanted. However, when I compiled this under Visual C++, I got back the original strings and the program executed fine. I tried dynamically allocating memory to the strings and copying them the "standard" way, but the only way that worked was using malloc() and free(), which I hear is discouraged in C++. While I'm curious about that, the real question I have is this: Why did the program work when compiled in VC++, but not with gcc? (This is one of many conflicts that I experienced while trying to make the code cross-platform.) Thanks in advance! -Carlos Nunez

  • Wanted to know in detail about how shared libraries work vis-a-vis static library.

    - by goldenmean
    Hello, I am working on creating and linking shared library (.so). While working with them, many questions popped up which i could not find satisying answers when i searched for them, hence putting them here. The questions about shared libraries i have are: 1.) How is shared library different than static library? What are the Key differences in way they are created, they execute? 2.) In case of a shared library at what point are the addresses where a particular function in shared library will be loaded and run from, given? Who gives those functions is load/run addresses? 3.) Will an application linked against shared library be slower in execution as compared to that which is linked with a static library? 4.) Will application executable size differ in these two cases? 5.) Can one do source level debugging of by stepping into functions defined inside a shared library? Is any thing extra needed to make these functions visible to the application? 6.) What are pros and cons in using either kind of library? Thanks. -AD

  • JQuery idleTimeout plugin: How to display the dialog after the session is timedout on ASP.NET MVC Pa

    - by Rita
    Hi I am working on migrating the ASP.NET apllication to MVC Framework. I have implemented session timeout for InActiveUser using JQuery idleTimeout plugin. I have set idletime for 30 min as below in my Master Page. So that After the user session is timedout of 30 Min, an Auto Logout dialog shows for couple of seconds and says that "You are about to be signed out due to Inactivity" Now after this once the user is logged out and redirected to Home Page. Here i again want to show a Dialog and should stay there saying "You are Logged out" until the user clicks on it. Here is my code in Master page: $(document).ready(function() { var SEC = 1000; var MIN = 60 * SEC; // http://philpalmieri.com/2009/09/jquery-session-auto-timeout-with-prompt/ <% if(HttpContext.Current.User.Identity.IsAuthenticated) {%> $(document).idleTimeout({ inactivity: 30 * MIN, noconfirm : 30 * SEC, redirect_url: '/Account/Logout', sessionAlive: 0, // 30000, //10 Minutes click_reset: true, alive_url: '', logout_url: '' }); <%} %> } Logout() Method in Account Controller: public virtual ActionResult Logout() { FormsAuthentication.SignOut(); return RedirectToAction(MVC.Home.Default()); } Appreciate your responses.

  • What is Ruby's analog to Python Metaclasses?

    - by Sean Copenhaver
    Python has the idea of metaclasses that, if I understand correctly, allow you to modify an object of a class at the moment of construction. You are not modifying the class, but instead the object that is to be created then initialized. Python (at least as of 3.0 I believe) also has the idea of class decorators. Again if I understand correctly, class decorators allow the modifying of the class definition at the moment it is being declared. Now I believe there is an equivalent feature or features to the class decorator in Ruby, but I'm currently unaware of something equivalent to metaclasses. I'm sure you can easily pump any Ruby object through some functions and do what you will to it, but is there a feature in the language that sets that up like metaclasses do? So again, Does Ruby have something similar to Python's metaclasses? Edit I was off on the metaclasses for Python. A metaclass and a class decorator do very similar things it appears. They both modify the class when it is defined but in different manners. Hopefully a Python guru will come in and explain better on these features in Python. But a class or the parent of a class can implement a __new__(cls[,..]) function that does customize the construction of the object before it is initialized with __init__(self[,..]).

  • stack overflow problem in program

    - by Jay
    So I am currently getting a strange stack overflow exception when i try to run this program, which reads numbers from a list in a data/text file and inserts it into a binary search tree. The weird thing is that when the program works when I have a list of 4095 numbers in random order. However when i have a list of 4095 numbers in increasing order (so it makes a linear search tree), it throws a stack overflow message. The problem is not the static count variable because even when i removed it, and put t=new BinaryNode(x,1) it still gave a stack overflow exception. I tried debugging it, and it broke at if (t == NULL){ t = new BinaryNode(x,count); Here is the insert function. BinaryNode *BinarySearchTree::insert(int x, BinaryNode *t) { static long count=0; count++; if (t == NULL){ t = new BinaryNode(x,count); count=0; } else if (x < t->key){ t->left = insert(x, t->left); } else if (x > t->key){ t->right = insert(x, t->right); } else throw DuplicateItem(); return t; }

  • Keyboard input: how to separate keycodes received from user

    - by Iulian Serbanoiu
    Hello, I am writing an application involving user input from the keyboard. For doing it I use this way of reading the input: #include <stdio.h> #include <termios.h> #include <unistd.h> int mygetch( ) { struct termios oldt, newt; int ch; tcgetattr( STDIN_FILENO, &oldt ); newt = oldt; newt.c_lflag &= ~( ICANON | ECHO ); tcsetattr( STDIN_FILENO, TCSANOW, &newt ); ch = getchar(); tcsetattr( STDIN_FILENO, TCSANOW, &oldt ); return ch; } int main(void) { int c; do{ c = mygetch(); printf("%d\n",c); }while(c!='q'); return 0; } Everyting works fine for letters digits,tabs but when hiting DEL, LEFT, CTRL+LEFT, F8 (and others) I receive not one but 3,4,5 or even 6 characters. The question is: Is is possible to make a separation of these characters (to actually know that I only hit one key or key combination). What I would like is to have a function to return a single integer value for any type of input (letter, digit, F1-F12, DEl, PGUP, PGDOWN, CTRL+A, CTRL+ALT+A, ALT+LEFT, etc). Is this possible? I'm interested in an idea to to this, the language doesn't matter much, though I'd prefer perl or c. Thanks, Iulian

  • Disabling normal link behaviour on click with an if statement in Jquery?

    - by Qwibble
    I've been banging my head with this all day, trying anything and everything I can think of to no gain. I'm no Jquery guru, so am hoping someone here can help me out. What I'm trying to do in pseudo code (concept) seems practical and easy to implement, but obviously not so =D What I have is a navigation sidebar, with sub menu's within some li's, and a link at the head of each li. When a top level link is clicked, I want the jquery to check if the link has a sibling ul. If it does, the link doesn't act like a link, but slides down the sibling sub nav. If there isn't one, the link should act normally. Here's where I'm at currently, what am I doing wrong? $('ul.navigation li a').not('ul.navigation li ul li a').click(function (){ if($(this).parent().contains('ul')){ $('ul.navigation li ul').slideUp(); $(this).siblings('ul').slideDown(); return false; } else{ alert('Link Clicked') // Maybe do some more stuff in here... } }); Any ideas?

    First is my touchesBegan function and then the struct that stores the values for my object. I have an array of these objects and I'm trying to figure out when I touch the screen if I'm touching an object on the screen. I don't know if I need to do this by iterating through all my objects and figure out if I'm touching an object that way or maybe there is an easier more efficient way. How is this usually handled? -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ [super touchesEnded:touches withEvent:event]; UITouch* touch = ([touches count] == 1 ?

  • MVC.NET custom validator is not working

    - by IvanMushketyk
    I want to write a custom validator for MVC.NET framework that checks if entered date is in the future. To do it, I wrote the following class: [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = true)] public sealed class InTheFutureAttribute : ValidationAttribute, IClientValidatable { private const string DefaultErrorMessage = "{0} should be date in the future"; public InTheFutureAttribute() : base(DefaultErrorMessage) { } public override string FormatErrorMessage(string name) { return string.Format(ErrorMessageString, name); } public override bool IsValid(object value) { DateTime time = (DateTime)value; if (time < DateTime.Now) { return false; } return true; } public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context) { var clientValidationRule = new ModelClientValidationRule() { ErrorMessage = FormatErrorMessage(metadata.GetDisplayName()), ValidationType = "wrongvalue" }; return new[] { clientValidationRule }; } } and added attribute to field that I want to check. On the View page I create input field in the following way: <div class="editor-label-search"> @Html.LabelFor(model => model.checkIn) </div> <div class="editor-field-search-date"> @Html.EditorFor(model => model.checkIn) <script type="text/javascript"> $(document).ready(function () { $('#checkIn').datepicker({ showOn: 'button', buttonImage: '/Content/images/calendar.gif', duration: 0, dateFormat: 'dd/mm/yy' }); }); </script> @Html.ValidationMessageFor(model => model.checkIn) </div> When I submit the form for the controller that requires model with checked attribute code in my validator is called and it returns false, but instead of displaying an error it just call my controller's action and send invalid model to it. Am I doing something wrong? How can I fix it? Thank you in advance.

    - by user272899
    I am having problems with the Jquery qtip plugin. It works fine in Firefox (see here http://movieo.no-ip.org/ hover over the first image). But doesn't work in IE. This is the code: $('.moviebox').each(function() { $(this).qtip({ content: $(this).children('.info'), show: 'mouseover', hide: 'mouseout', style: { name: 'light' }, position: { corner: { target: 'rightbottom', tooltip: 'bottomleft' } } }); }); And the html <!--start moviebox--> <div class="moviebox"> <a href="#"> <img src="http://1.bp.blogspot.com/_mySxtRcQIag/S6deHcoChaI/AAAAAAAAObc/Z1Xg3aB_wkU/s200/rising_sun.jpg" /> </a> <!--start infobox--> <div class="info"> <span>Rising Sun (2006)</span> <div class="description"><strong>Description:</strong><br /> test test test test test test test test test test test test test test test test</div> <img src="http://1.bp.blogspot.com/_mySxtRcQIag/S6deHcoChaI/AAAAAAAAObc/Z1Xg3aB_wkU/s200/rising_sun.jpg" /> <div class="cast"><strong>Cast:</strong><br /> Sean connery</div> <div class="rating"><strong>Rating:</strong><br />5stars</div> </div> <!--end infobox--> </div> <!--end moviebox--> Why wouldn't that work in IE????? Beats me. Checkout movieo.no-ip.org for the whole source

  • Loading the target of a link in a <DIV> via jQuery's .live event into the same <DIV>??

    - by Martin Pescador
    Hello together I call a certain div from another page with jquery to be loaded into a div on my main page like this: <script type="text/javascript"> $("#scotland").load("http://www.example.com/scotland .gallery"); </script> <div id="scotland"></div> The div I call is a piece of code which is automatically generated by a CMS made simple module, by the way. Now it comes to my problem: The .gallery div I call, looks, a little simplified, like this: <div class="gallery"> <span><img src="http://www.example.com/scotlandimage1.jpg"></span> <span class="imgnavi"><a href="link_to_next_page_with_one_image">Next image</href></span> </div> I want the "next image"-link to load the next page into the .gallery div (it is always a page with one image on it). But what it does, is, it opens the new page http://www.example.com/scotland only. I tried to use jquerys .live event to load the linked page (that would be "scotlandimage2" and the navigation, as you can see in the upper part - not only the image!), but I must have done something wrong. I tried different ways, but never got it to work. This was my last try: $(".imgnavi a").click(function() { var myUrl = $(this).attr("href"); $(".gallery").load(myUrl); return false; }); I have to admit that I am very new to jquery... But does someone know what I did wrong (do I even follow the right handlers?)? Thanks very much in advance! Martin

  • Unexpected Event Behavior When Using VB6 with COM Interop (C#)

    - by Randal
    We are using a COM Interop (C#) to allow for a VB6 application to send data to a server. Once the server receives the data, the managed code will raise a DataSent event. This event is only fired after a correlation ID is returned to the original caller. About 1% of the time, we've encountered VB6 executing the raised event before finishing the function that originally sent the data. Using the following code: ' InteropTester.COMEvents is the C# object ' Dim WithEvents m_ManagedData as InteropTester.COMEvents Private Sub send_data() Set m_ManagedData = new COMEvents Dim id as Integer ' send 5 to using the managed interop object ' id = m_ManagedData.SendData(5) LogData "ID " & id & " was returned" m_correlationIds.Add id End Sub Private Sub m_ManagedData_DataSent(ByVal sender as Variant, ByVal id as Integer) LogData "Data was successfully sent to C#" ' check if the returned ID is in the m_correlationIds collection goes here' End Sub We can verify that the id is returned with a value when we call m_ManagedData.SendData(5), but the logs then show that the m_ManagedData_DataSent is occasionally called before send_data ends. How is possible for VB6 to access the Message Loop to know that the DataSent event was raised before exiting send_data()? We are not calling DoEvents and everything within VB6 is synchronous. Thanks in advance for your help.

  • libpng cannot read an image properly

    - by jonathanasdf
    Here is my function... I don't know why it's not working. The resulting image looks nothing like what the .png looks like. But there's no errors either. bool Bullet::read_png(std::string file_name, int pos) { png_structp png_ptr; png_infop info_ptr; FILE *fp; if ((fp = fopen(file_name.c_str(), "rb")) == NULL) { return false; } png_ptr = png_create_read_struct(PNG_LIBPNG_VER_STRING, NULL, NULL, NULL); if (png_ptr == NULL) { fclose(fp); return false; } info_ptr = png_create_info_struct(png_ptr); if (info_ptr == NULL) { fclose(fp); png_destroy_read_struct(&png_ptr, NULL, NULL); return false; } if (setjmp(png_jmpbuf(png_ptr))) { png_destroy_read_struct(&png_ptr, &info_ptr, NULL); fclose(fp); return false; } png_init_io(png_ptr, fp); png_read_png(png_ptr, info_ptr, PNG_TRANSFORM_STRIP_16 | PNG_TRANSFORM_SWAP_ALPHA | PNG_TRANSFORM_EXPAND, NULL); png_uint_32 width = png_get_image_width(png_ptr, info_ptr); png_uint_32 height = png_get_image_height(png_ptr, info_ptr); imageData[pos].width = width; imageData[pos].height = height; png_bytepp row_pointers; row_pointers = png_get_rows(png_ptr, info_ptr); imageData[pos].data = new unsigned int[width*height]; for (unsigned int i=0; i < height; ++i) { memcpy(&imageData[pos].data[i*width], &row_pointers[i], width*sizeof(unsigned int)); } png_destroy_read_struct(&png_ptr, &info_ptr, NULL); fclose(fp); for (unsigned int i=0; i < height; ++i) { for (unsigned int j=0; j < width; ++j) { unsigned int val = imageData[pos].data[i*width+j]; if (val != 0) { unsigned int a = ((val >> 24)); unsigned int r = (((val - (a << 24)) >> 16)); unsigned int g = (((val - (a << 24) - (r << 16)) >> 8)); unsigned int b = (((val - (a << 24) - (r << 16) - (g << 8)))); // for debugging std::string s(AS3_StringValue(AS3_Int(i*width+j))); s += " "; s += AS3_StringValue(AS3_Int(val)); s += " "; s += AS3_StringValue(AS3_Int(a)); s += " "; s += AS3_StringValue(AS3_Int(r)); s += " "; s += AS3_StringValue(AS3_Int(g)); s += " "; s += AS3_StringValue(AS3_Int(b)); AS3_Trace(AS3_String(s.c_str())); } } } return true; } ImageData is just a simple struct to keep x, y, width, and height, and imageData is an array of that struct. struct ImageData { int x; int y; int width; int height; unsigned int* data; }; Here is a side by side screenshot of the input and output graphics (something I made in a minute for testing), and this was after setting alpha to 255 in order to make it show up (because the alpha I was getting back was 1). Left side is original, right side is what happened after reading it through this function. Scaled up 400% for visibility.
