  • Images in the project NOT adding to array - don't know why.

    - by Sam Jarman
    Hi there, I have to sets of images. Each set has 16 images. One set is called 0.png through to 15.png the other is a0.png through to a15.png. In my app, it loads each one dependent on a variable (which by logging, I have proved it works) here is the code [MemoryManager sharedMemoryManager]; NSLog(@"THEME: %@", [MemoryManager sharedMemoryManager].themeName); imageArray = [[NSMutableArray alloc] init]; if([MemoryManager sharedMemoryManager].themeName == @"hand"){ NSLog(@"Here 2"); [imageArray addObject:[UIImage imageNamed:@"0.png"]]; // [imageArray addObject:[UIImage imageNamed:@"1.png"]];//1 [imageArray addObject:[UIImage imageNamed:@"2.png"]];//2 [imageArray addObject:[UIImage imageNamed:@"3.png"]];//3 [imageArray addObject:[UIImage imageNamed:@"4.png"]];//4 [imageArray addObject:[UIImage imageNamed:@"5.png"]];//5 [imageArray addObject:[UIImage imageNamed:@"6.png"]];//6 [imageArray addObject:[UIImage imageNamed:@"7.png"]];//7 [imageArray addObject:[UIImage imageNamed:@"8.png"]];//8 [imageArray addObject:[UIImage imageNamed:@"9.png"]];//9 [imageArray addObject:[UIImage imageNamed:@"10.png"]];//10 [imageArray addObject:[UIImage imageNamed:@"11.png"]];//11 [imageArray addObject:[UIImage imageNamed:@"12.png"]];//12 [imageArray addObject:[UIImage imageNamed:@"13.png"]];//13 [imageArray addObject:[UIImage imageNamed:@"14.png"]];//14 [imageArray addObject:[UIImage imageNamed:@"15.png"]];//15 } if([MemoryManager sharedMemoryManager].themeName == @"letters"){ NSLog(@"Here 3"); //[imageArray removeAllObjects]; [imageArray addObject:[UIImage imageNamed:@"a0.png"]]; // [imageArray addObject:[UIImage imageNamed:@"a1.png"]];//1 [imageArray addObject:[UIImage imageNamed:@"a2.png"]];//2 [imageArray addObject:[UIImage imageNamed:@"a3.png"]];//3 [imageArray addObject:[UIImage imageNamed:@"a4.png"]];//4 [imageArray addObject:[UIImage imageNamed:@"a5.png"]];//5 [imageArray addObject:[UIImage imageNamed:@"a6.png"]];//6 [imageArray addObject:[UIImage imageNamed:@"a7.png"]];//7 [imageArray addObject:[UIImage imageNamed:@"a8.png"]];//8 [imageArray addObject:[UIImage imageNamed:@"a9.png"]];//9 [imageArray addObject:[UIImage imageNamed:@"a10.png"]];//10 [imageArray addObject:[UIImage imageNamed:@"a11.png"]];//11 [imageArray addObject:[UIImage imageNamed:@"a12.png"]];//12 [imageArray addObject:[UIImage imageNamed:@"a13.png"]];//13 [imageArray addObject:[UIImage imageNamed:@"a14.png"]];//14 [imageArray addObject:[UIImage imageNamed:@"a15.png"]];//15 NSLog(@"Here 4"); } The log says 2010-05-26 21:30:57.092 Memory[22155:207] Here 1 2010-05-26 21:30:57.093 Memory[22155:207] THEME: letters 2010-05-26 21:30:57.095 Memory[22155:207] Here 3 2010-05-26 21:30:57.109 Memory[22155:207] Here 4 The images are in the same folder the .xproj file is.

  • PayPal IPN validation

    - by denis_n
    Following is from PayPal Order Management Integration Guide: Processing the PayPal Response to Your Postback PayPal responds to your postbacks with a single word in the body of the response: VERIFIED or INVALID. When you receive a VERIFIED postback response, perform the following checks on data in the IPN: Check that the payment_status is Completed. If the payment_status is Completed, check the txn_id against the previous PayPal transaction that you processed to ensure it is not a duplicate. Check that the receiver_email is an email address registered in your PayPal account. Check that the price, carried in mc_gross, and the currency, carried in mc_currency, are correct for the item, carried in item_name or item_number. After you complete the above checks, notification validation is complete. You can update your database with the information provided, and you can initiate other appropriate automated back-end processing. <form action="https://www.paypal.com/cgi-bin/webscr" method="post"> <input type="hidden" name="cmd" value="_cart" /> <input type="hidden" name="upload" value="1" /> <input type="hidden" name="business" value="GXLC9H9VFPLQE"> ..... <input type="submit" name="Submit" value="Submit" /> </form> In step 3 I should check receiver_email, but I don't want to. I don't want to keep my paypal account email in my application. My question is: can I check business variable instead?

  • Async Load JavaScript Files with Callback

    - by Gcoop
    Hi All, I am trying to write an ultra simple solution to load a bunch of JS files asynchronously. I have the following script below so far. However the callback is sometimes called when the scripts aren't actually loaded which causes a variable not found error. If I refresh the page sometimes it just works because I guess the files are coming straight from the cache and thus are there quicker than the callback is called, it's very strange? var Loader = function () { } Loader.prototype = { require: function (scripts, callback) { this.loadCount = 0; this.totalRequired = scripts.length; this.callback = callback; for (var i = 0; i < scripts.length; i++) { this.writeScript(scripts[i]); } }, loaded: function (evt) { this.loadCount++; if (this.loadCount == this.totalRequired && typeof this.callback == 'function') this.callback.call(); }, writeScript: function (src) { var self = this; var s = document.createElement('script'); s.type = "text/javascript"; s.async = true; s.src = src; s.addEventListener('load', function (e) { self.loaded(e); }, false); var head = document.getElementsByTagName('head')[0]; head.appendChild(s); } } Is there anyway to test that a JS file is completely loaded, without putting something in the actual JS file it's self, because I would like to use the same pattern to load libraries out of my control (GMaps etc). Invoking code, just before the tag. var l = new Loader(); l.require([ "ext2.js", "ext1.js"], function() { var config = new MSW.Config(); Refraction.Application().run(MSW.ViewMapper, config); console.log('All Scripts Loaded'); }); Thanks for any help.

  • Symfony forms question (restoring selected value of a dynamically populated sfWidgetFormSelect widge

    - by Stick it to THE MAN
    I am using Symfony 1.3.2 with Propel ORM on Ubuntu 9.10. I have developed a form that dynamically populates a select widget with cities in a selected country, using AJAX. Before the data entered on the form is saved, I validate the form. If validation fails, the form is presented back to the user for correction. However, because the country list is dynamically generated, the form that is presented for correction does not have a valid city selected (it is empty, since the country widget has not changed yet). This is inconvenient for the user, because it means they have to select ANOTHER country (so the change event is fired), and then change back to the original country they selected, then FINALLY select the city which they had last selected. All of this is forced on the user because another (possibly unrelated) field did not vaildate. I tried $form-getValue('widget_name'), called immediately after $form-bind(), but it seems (infact, IIRC, if form fails to validate, all the values are reset to null) - so that does not work. I am currently trying a nasty hack which involves the use of directly accesing the input (i.e. tainted) data via $_POST, and setting them into a flash variable - but I feel its a very nasty hack) What I'm trying to do is a common use case scenario - is there a better way to do this, than hacking around with $_POST etc?

  • UINavigationController crash because of pushing and poping UIViewControllers

    - by Wayne Lo
    My question is related to my discovery of a reason for UINavigationController to crash. So I will tell you about the discovery first. Please bare with me. The issue: I have a UINavigationController as as subview of UIWindow, a rootViewController class and a custom MyViewController class. The following steps will get a Exc_Bad_Access, 100% reproducible.: [myNaviationController pushViewController:myViewController_1stInstance animated:YES]; [myNaviationController pushViewController:myViewController_2ndInstance animated:YES]; Hit the left back tapBarItem twice (pop out two of the myViewController instances) to show the rootViewController. After a painful 1/2 day of try and error, I finally figure out the answer but also raise a question. The Solutio: I declared many objects in the .m file as a lazy way of declaring private variables to avoid cluttering the .h file. For instance, #impoart "MyViewController.h" NSMutableString*variable1; @implement ... -(id)init { ... varialbe1=[[NSMutableString alloc] init]; ... } -(void)dealloc { [variable1 release]; } For some reasons, the iphone OS may loose track of these "lazy private" variables memory allocation when myViewController_1stInstance's view is unloaded (but still in the navigation controller's stacks) after loading the view of myViewController_2ndInstance. The first time to tap the back tapBarItem is ok since myViewController_2ndInstance'view is still loaded. But the 2nd tap on the back tapBarItem gave me hell because it tried to dealloc the 2nd instance. Executing [variable release] resulted in Exc_Bad_Access because it pointed randomly (loose pointer). To fix this problem is simple, declare variable1 as a @private in the .h file. Here is my Question: I have been using the "lazy private" variables for quite some time without any issues until they are involved in UINavigationController. Is this a bug in iPhone OS? Or there is a fundamental misunderstanding on my part about Objective C? Please help.

  • Request.IsAuthenticated problem with Cache in ASP.NET

    - by Julien
    Hello guys or girls..! I'm new in ASP.NET and I have a problem...

  • Maintaining ISAPI Rewrite Path with the ASP.NET tilde (~)

    - by Adam
    My team is upgrading from ASP.NET 3.5 to ASP.NET 4.0. We are currently using Helicon ISAPI Rewrite to map http://localhost/<account-name>/default.aspx to http://localhost/<virtual-directory>/default.aspx?AccountName=<account-name> where <account-name> is a query string variable and <virtual-directory> is a virtual directory (naturally). Before the upgrade the tilde (~) resolved to http://localhost/<account-name>/... (which I want it to do) and after the upgrade the tilde resolves to http://localhost/<virtual-directory>/... which results in an error because the <account-name> query string is required. I'd like to avoid going down the road of replacing everything with relative paths because there are several features in our system that use the entire URL instead of just the relative path. For what it's worth I'm using IIS7 in Windows 7, Visual Studio 2010 with ASP.NET 4.0 and the 64 bit Helicon ISAPI Rewrite. If I switch back to the ASP.NET 3.5 version then it still works fine (leading me to believe nothing changed in IIS unless it's within the 4.0 app pool - when I switch back and forth between 3.5 and 4.0 I have to change the app pool in IIS). Any ideas? Thanks in advance!

  • C# unaccurate timer?

    - by Ivan
    Hi there, I'm developing an application and I need to get the current date from a server (it differs from the machine's date). I receive the date from the server and with a simple Split I create a new DateTime: globalVars.fec = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, int.Parse(infoHour[0]), int.Parse(infoHour[1]), int.Parse(infoHour[2])); globalVars is a class and fec is a public static variable so that I can access it anywhere in the application (bad coding I know...). Now I need to have a timer checking if that date is equal to some dates I have stored in a List and if it is equal I just call a function. List<DateTime> fechas = new List<DateTime>(); Before having to obtain the date from a server I was using computer's date, so to check if the dates matched I was using this: private void timerDatesMatch_Tick(object sender, EventArgs e) { DateTime tick = DateTime.Now; foreach (DateTime dt in fechas) { if (dt == tick) { //blahblah } } } Now I have the date from the server so DateTime.Now can't be used here. Instead I have created a new timer with Interval=1000 and on tick I'm adding 1 second to globalVars.fec using: globalVars.fec = globalVars.fec.AddSeconds(1); But the clock isn't accurate and every 30 mins the clock loses about 30 seconds. Is there another way of doing what I'm trying to do? I've thought about using threading.timer instead but I need to have access to other threads and non-static functions. Thanks in advance, Ivan

  • Jquery image preview plugin issue...

    - by Pandiya Chendur
    I have a problem with an image preview that comes up when you hover over a thumbnail. I can change the distance between the preview and the cursor, but if a thumbnail is close to the side of the window, the preview cant fit and you only see part of it.. hope that makes sense... is there a way to make it so that if the preview doesnt fit, it will show up on the other side of the cursor?.... Here is the script... this.imagePreview = function() { /* CONFIG */ xOffset = 10; yOffset = 30; // these 2 variable determine popup's distance from the cursor // you might want to adjust to get the right result /* END CONFIG */ $("a.preview").hover(function(e) { this.t = this.title; this.title = ""; var c = (this.t != "") ? "<br/>" + this.t : ""; $("body").append("<p id='preview'> <img src='" + this.href + "' alt='Image preview' />" + c + "</p>"); $("#preview") .css("top", (e.pageY - xOffset) + "px") .css("left", (e.pageX + yOffset) + "px") .fadeIn("slow"); }, function() { this.title = this.t; $("#preview").remove(); }); $("a.preview").mousemove(function(e) { $("#preview") .css("top", (e.pageY - xOffset) + "px") .css("left", (e.pageX + yOffset) + "px"); }); }; // starting the script on page load $(document).ready(function() { imagePreview(); }); EDIT: see what i am getting, http://img202.imageshack.us/img202/4991/browserpreviewf.jpg my image at the right corner of the page so when i hover the img my preview goes even further right that is besides the page scrollbar half the preview is available.... How to get the preview to the left of the cursor..

  • pthreads: reader/writer locks, upgrading read lock to write lock

    - by ScaryAardvark
    I'm using read/write locks on Linux and I've found that trying to upgrade a read locked object to a write lock deadlocks. i.e. // acquire the read lock in thread 1. pthread_rwlock_rdlock( &lock ); // make a decision to upgrade the lock in threads 1. pthread_rwlock_wrlock( &lock ); // this deadlocks as already hold read lock. I've read the man page and it's quite specific. The calling thread may deadlock if at the time the call is made it holds the read-write lock (whether a read or write lock). What is the best way to upgrade a read lock to a write lock in these circumstances.. I don't want to introduce a race on the variable I'm protecting. Presumably I can create another mutex to encompass the releasing of the read lock and the acquiring of the write lock but then I don't really see the use of read/write locks. I might as well simply use a normal mutex. Thx

  • Struggling with currency in Cocoa.

    - by Meltemi
    I'm trying to do something I'd think would be fairly simple: Let a user input a dollar amount, store that amount in an NSNumber (NSDecimalNumber?), then display that amount formatted as currency again at some later time. My trouble is not so much with the setNumberStyle:NSNumberFormatterCurrencyStyle and displaying floats as currency. The trouble is more with how said numberFormatter works with this UITextField. I can find few examples. This thread from November and this one give me some ideas but leaves me with more questions. I am using the UIKeyboardTypeNumberPad keyboard and understand that I should probably show $0.00 (or whatever local currency format is) in the field upon display then as a user enters numerals to shift the decimal place along: Begin with display $0.00 Tap 2 key: display $0.02 Tap 5 key: display $0.25 Tap 4 key: display $2.54 Tap 3 key: display $25.43 Then [numberFormatter numberFromString:textField.text] should give me a value I can store in my NSNumber variable. Sadly I'm still struggling: Is this really the best/easiest way? If so then maybe someone can help me with the implementation? I feel UITextField may need a delegate responding to every keypress but not sure what, where and how to implement it?! Any sample code? I'd greatly appreciate it! I've searched high and low... Edit1: So I'm looking into NSFormatter's stringForObjectValue: and the closest thing I can find to what benzado recommends: UITextViewTextDidChangeNotification. Having really tough time finding sample code on either of them...so let me know if you know where to look?

  • Kohana multi language website

    - by Sobek
    .I'm trying to set up a multi language website with kohana v3, following this tutorial: http://kerkness.ca/wiki/doku.php?id=example_of_a_multi-language_website Routing to a controller or action within i.e. website/controller/action seems to work as the url is properly redirected to website/lang/controller/action. However this is not working for ajax request calls. I have to manually edit the url with the appropriate language, to successfully retrieve the data. This also applies for anchors on the html page. In addition to this problem, the overflow parameter 'id' also doesn't work. It takes the 'lang' variable as its parameter. I have setup my default route just like in the tutorial i.e.: Route::set('default', '((<lang>)(/)(<controller>)(/<action>(/<id>)))', array('lang' => "({$langs_abr})",'id'=>'.+')) ->defaults(array('lang' => $default_lang,'controller' => welcome', 'action' => 'index')); Any help is much appreciated !

  • Using section header in Sendgrid

    - by Zefiryn
    I am trying to send emails through sendgrid in Zend application. I copy the php code from the sendgrid documentation (smtapi class and swift). I create a template with places that should be substituted with %variable%. Now I create headers for sendgrid as defined here: http://docs.sendgrid.com/documentation/api/smtp-api/developers-guide/ In result I get something looking like this: { "to": ["[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]"], "sub": {"%firstname%": ["Benny", "Chaim", "Ephraim", "Yehuda", "will"]}, "section": {"%postername%": "Rabbi Yitzchak Lieblich", "%postermail%": "[email protected]", "%categoryname%": "General", "%threadname%": "Completely new thread", "%post%": "This thread is to inform you about something very important", "%threadurl%": "http:\/\/hb.local\/forums\/general\/thread\/143", "%replyto%": "http:\/\/hb.local\/forums\/general\/thread\/143", "%unsubscribeurl%": "http:\/\/hb.local\/forums\/settings\/", "%subscribeurl%": "http:\/\/hb.local\/forums\/subscribe-thread\/id\/143\/token\/1b20eb7799829e22ba2d48ca0867d3ce"} } Now while all data defined in "sub" changes I cannot make section work. In the final email I still got %postername%. When I move this data to sub and repeat them for each email everything is working fine. Has anyone a clue what I am doing wrong?

  • Common coding style for Python?

    - by Oscar Carballal
    Hi, I'm pretty new to Python, and I want to develop my first serious open source project. I want to ask what is the common coding style for python projects. I'll put also what I'm doing right now. 1.- What is the most widely used column width? (the eternal question) I'm currently sticking to 80 columns (and it's a pain!) 2.- What quotes to use? (I've seen everything and PEP 8 does not mention anything clear) I'm using single quotes for everything but docstrings, which use triple double quotes. 3.- Where do I put my imports? I'm putting them at file header in this order. import sys import -rest of python modules needed- import whatever import -rest of application modules- <code here> 4.- Can I use "import whatever.function as blah"? I saw some documents that disregard doing this. 5.- Tabs or spaces for indenting? Currently using 4 spaces tabs. 6.- Variable naming style? I'm using lowercase for everything but classes, which I put in camelCase. Anything you would recommend?

  • PLT Scheme Memory

    - by Eric
    So I need some help with implementing a Make-memory program using Scheme. I need two messages 'write and 'read. So it would be like (mymem 'write 34 -116) and (mymem 'read 99) right? and (define mymem (make-memory 100)).....How would I implement this in scheme? using an Alist???I need some help coding it. I have this code which makes make-memory a procedure and when you run mymem you get ((99.0)) and what i need to do is recur this so i get an alist with dotted pairs to ((0.0)). So any suggestions on how to code this?? Does anyone have any ideas what I could do to recur and make messages Write and read?? (define make-memory (lambda (n) (letrec ((mem '()) (dump (display mem))) (lambda () (if (= n 0) (cons (cons n 0) mem) mem) (cons (cons (- n 1) 0) mem)) (lambda (msg loc val) (cond ((equal? msg 'read) (display (cons n val))(set! n (- n 1))) ((equal? msg 'write) (set! mem (cons val loc)) (set! n (- n 1)) (display mem))))))) (define mymem (make-memory 100)) Yes this is an assignment but I wrote this code. I just need some help or direction. And yes I do know about variable-length argument lists.

  • Flex: How to refresh/repaint a chart?

    - by Rob
    I have a chart for which the data is provided asynchronously via a CallResponder (used with a RemoteObject). However, it does not seem possible to update the chart with the data after it has been initially drawn. Here are the relevant snippets of (simplified) code: // code below is in the application MXML <mx:CallResponder id="result" result="resultHandler(event)" /> private function resultHandler(event:ResultEvent):void { // panel is an instance of ChartPanel this.panel.init(event.result); } // invoked when user clicks a button private function displayChart():void { this.currentState = "ShowChart"; result.token = remoteObject.getUrlStatistics(); } // code below is in ChartPanel <mx:BarChart id="chart" /> public function init(value:Object):void { var xml:XMLList = XMLList(value); var data:ArrayCollection = new ArrayCollection(); for each (var element:XML in xml.children()) { // not shown: extract value out of XML, put in ArrayList data.addItem(...); } this.chart.dataProvider = data; } The result is that it draws an empty chart. the resultHandler function or init function in ChartPanel needs to trigger a repaint or something similar. I have tried: Firing a collection modified event after assigning it to chart.dataProvider calling invalidateDisplayList (tried with all components) binding the chart data provider to a variable, and doing the above. changing the view state on the last line of resultHandler. None of them worked. When I fetch the data and cache it locally, then use it to call init synchronously, the chart displays correctly. What am I missing here?

  • Getting web page after calling DownloadStringAsync()?

    - by OverTheRainbow
    Hello I don't know enough about VB.Net yet to use the richer HttpWebRequest class, so I figured I'd use the simpler WebClient class to download web pages asynchronously (to avoid freezing the UI). However, how can the asynchronous event handler actually return the web page to the calling routine? Imports System.Net Public Class Form1 Private Shared Sub DownloadStringCallback2(ByVal sender As Object, ByVal e As DownloadStringCompletedEventArgs) If e.Cancelled = False AndAlso e.Error Is Nothing Then Dim textString As String = CStr(e.Result) 'HERE : How to return textString to the calling routine? End If End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim client As WebClient = New WebClient() AddHandler client.DownloadStringCompleted, AddressOf DownloadStringCallback2 Dim uri As Uri = New Uri("http://www.google.com") client.DownloadStringAsync(uri) 'HERE : how to get web page back from callback function? End Sub End Class Thank you. Edit: I added a global, shared variable and a While/DoEvents/EndWhile, but there's got to be a cleaner way to do this :-/ Public Class Form1 Shared page As String Public Shared Sub AlertStringDownloaded(ByVal sender As Object, ByVal e As DownloadStringCompletedEventArgs) ' If the string request went as planned and wasn't cancelled: If e.Cancelled = False AndAlso e.Error Is Nothing Then page = CStr(e.Result) End If End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim wc As New WebClient AddHandler wc.DownloadStringCompleted, AddressOf AlertStringDownloaded page = Nothing wc.DownloadStringAsync(New Uri("http://www.google.com")) 'Better way to wait until page has been filled?

  • Call to undefined function query() - using PDO in PHP

    - by webworm
    I have a written a script in PHP that reads from data from a MySQL database. I am new to PHP and I have been using the PDO library. I have been developing on a Windows machine using the WAMP Server 2 and all has been working well. However, when I uploaded my script to the LINUX server where it will be used I get the following error when I run my script. Fatal error: Call to undefined function query() This is the line where the error is occuring ... foreach($dbconn->query($sql) as $row) The variable $dbconn is first defined in my dblogin.php include file which I am listing below. <?php // Login info for the database $db_hostname = 'localhost'; $db_database = 'MY_DATABASE_NAME'; $db_username = 'MY_DATABASE_USER'; $db_password = 'MY_DATABASE_PASSWORD'; $dsn = 'mysql:host=' . $db_hostname .

I was wondering if the PDO library was installed but from what I thought it was installed by default as part of PHP v5. The script is running on an Ubuntu (5.0.51a-3ubuntu5.4) machine and the PHP version is 5.2.4. Thank you for any suggestions. I am really lost on this.

  • Auto-sizing and positioning in Flex

    - by Addsy
    I am working on a flex app that uses XML templates to dynamically create DisplayObjects. These templates define different layouts that can be used for each page of content in the app (ie , 2 columns, 3 columns etc etc). The administrator can select from one of these and populate each area with their content. The templates add one of 3 types of DisplayObject - HBox, VBox or a third component - LibraryContentContainer (an mxml component that is defined as part of the app) - which is effectively a canvas element with a TextArea inside. The problem that I am getting is that I need each of these areas to automatically resize to fit the length of the content but don't seem to be able to find an effective way to do so. In the LibraryContentContainer, when the value of the TextArea is set, I am calling .validateNow() on the LibraryContentContainer. I then set the height property on both the TextArea and LibraryContentContainer to match the textHeight property of the TextArea. In the following example, this is the LibraryContentContainer, viewer is the TextArea and the value property of the TextArea is bound to this.__Value. v is the variable containing the content for the textarea this.__Value = v; this.validateNow(); this.viewer.height = this.viewer.textHeight; this.height = this.viewer.height; This works to a degree in that the TextArea grows or shrinks depending on the length of content, but it's still not great - sometimes there are still vertical scrollbars even tho the size of the TextArea has grown. Anyone got any ideas? Thanks Adam

  • Parsing XML with the PHP XMLReader

    - by coffeecoder
    Hi Guys, I am writing program that reads in some XML from the $_POST variable and then parses using the PHP XMLReader and the data extracted input into a database. I am using the XMLReader as the XML supplied will more than likely be too big to place into memory. However I am having some issues, my XML and basic code as are follows: '<?xml version="1.0"?> <data_root> <data> <info>value</info> </data> <action>value</action> </data_root>' $request = $_REQUEST['xml']; $reader = new XMLReader(); $reader->XML($request); while($reader->read()){ //processing code } $reader->close() My problem is that the code will work perfectly if the XML being passed does not have the <?xml version="1.0"?> line, but if i include it, and it will be included when the application goes into a live production environment, the $reader->read() code for the while loop does not work and the XML is not parsed within the while loop. Has anyone seen similar behaviour before or knows why this could be happening? Thanks in advance.

  • Changing font size of legend title in Python pylab rose/polar plot

    - by LaurieW
    I'm trying to change the font size of the title of an existing legend on a rose, or 'polar', plot. Most of the code was written by somebody else, who is away. I've added:- ax.legend(title=legend_title) setp(l.get_title(), fontsize=8) to add the title 'legend_title', which is a variable that the user enters a string for in a a different function that uses this code. The second line of this doesn't return an error but doesn't appear to do anything either. The complete code is below. 'Rose' and 'RoseAxes' are modules/functions written by somebody. Does anyone know of a way to change the legend title font size? I've found some examples for normal plots but can't find any for rose/polar plots. from Rose.RoseAxes import RoseAxes from pylab import figure, title, setp, close, clf from PlotGeneration import color_map_xml fig = figure(1) rect = [0.02, 0.1, 0.8, 0.8] ax = RoseAxes(fig, rect, axisbg='w') fig.add_axes(ax) if cmap == None: (XMLcmap,colors) = color_map_xml.get_cmap('D:/HRW/VET/HrwPyLibs/ColorMapLibrary/paired.xml',255) else: XMLcmap = cmap bqs = kwargs.pop('CTfigname', None) ax.box(Dir, U, bins = rose_binX, units = unit, nsector = nsector, cmap = XMLcmap, lw = 0, **kwargs ) l = ax.legend() ax.legend(title=legend_title) setp(l.get_texts(), fontsize=8) setp(l.get_title(), fontsize=8) Thanks for any help

    it's work only once. at second button click, occured nothing. if I change budilnik variable at i_budilnik or var budilnik, occured nothing at first and other clicks! Where is the problem? <div><form name="alert"><input type="text" name="hour" /><input type="text" name="min"/><input type="button" value="ok" onclick="budilnik(this.form)"></form><font color=#660000 size=20 face=Tahoma><span id="hours"></span> </div> <script type="text/javascript"> function budilnik(form) { budilnik=1; min=form.min.value; hour=form.hour.value; } obj_hours=document.getElementById("hours"); function wr_hours() { time=new Date(); time_min=time.getMinutes(); time_hours=time.getHours(); time_wr=((time_hours<10)?"0":"")+time_hours; time_wr+=":"; time_wr+=((time_min<10)?"0":"")+time_min; time_wr=time_wr; obj_hours.innerHTML=time_wr; if (i_budilnik==1) { if (min==time_min) { if (hour==time_hours) { alert('welldone'); budilnik=0; } } } } wr_hours(); setInterval("wr_hours();",1000); </script>

  • Are endless loops in bad form?

    - by rlbond
    So I have some C++ code for back-tracking nodes in a BFS algorithm. It looks a little like this: typedef std::map<int> MapType; bool IsValuePresent(const MapType& myMap, int beginVal, int searchVal) { int current_val = beginVal; while (true) { if (current_val == searchVal) return true; MapType::iterator it = myMap.find(current_val); assert(current_val != myMap.end()); if (current_val == it->second) // end of the line return false; current_val = it->second; } } However, the while (true) seems... suspicious to me. I know this code works, and logically I know it should work. However, I can't shake the feeling that there should be some condition in the while, but really the only possible one is to use a bool variable just to say if it's done. Should I stop worrying? Or is this really bad form. EDIT: Thanks to all for noticing that there is a way to get around this. However, I would still like to know if there are other valid cases.

  • GPGPU programming with OpenGL ES 2.0

    - by Albus Dumbledore
    I am trying to do some image processing on the GPU, e.g. median, blur, brightness, etc. The general idea is to do something like this framework from GPU Gems 1. I am able to write the GLSL fragment shader for processing the pixels as I've been trying out different things in an effect designer app. I am not sure however how I should do the other part of the task. That is, I'd like to be working on the image in image coords and then outputting the result to a texture. I am aware of the gl_FragCoords variable. As far as I understand it it goes like that: I need to set up a view (an orthographic one maybe?) and a quad in such a way so that the pixel shader would be applied once to each pixel in the image and so that it would be rendering to a texture or something. But how can I achieve that considering there's depth that may make things somewhat awkward to me... I'd be very grateful if anyone could help me with this rather simple task as I am really frustrated with myself. UPDATE It seems I'll have to use an FBO, getting one like this: glBindFramebuffer(...)

  • Rotate UIViewController to counteract changes in UIInterfaceOrientation

    - by Peter Hajas
    Hi there, I've been searching a lot on this, and can't find anything to help me. I have a UIViewController contained within another UIViewController. When the parent UIViewController rotates, say from Portrait to LandscapeLeft, I want to make it look as though the child didn't rotate. That is to say. I want the child to have the same orientation to the sky regardless of the parent's orientation. If it has a UIButton that's upright in Portrait, I want the right-side of the button to be "up" in UIInterfaceOrientationLandscapeLeft. Is this possible? Currently, I'm doing really gross stuff like this: -(void) rotate:(UIInterfaceOrientation)fromOrientation: toOr:(UIInterfaceOrientation)toOrientation { if(((fromOrientation == UIInterfaceOrientationPortrait) && (toOrientation == UIInterfaceOrientationLandscapeRight)) || ((fromOrientation == UIInterfaceOrientationPortraitUpsideDown) && (toOrientation == UIInterfaceOrientationLandscapeLeft))) { } if(((fromOrientation == UIInterfaceOrientationLandscapeRight) && (toOrientation == UIInterfaceOrientationPortraitUpsideDown)) || ((fromOrientation == UIInterfaceOrientationLandscapeLeft) && (toOrientation == UIInterfaceOrientationPortrait))) { } if(((fromOrientation == UIInterfaceOrientationPortrait) && (toOrientation == UIInterfaceOrientationLandscapeLeft)) || ((fromOrientation == UIInterfaceOrientationPortraitUpsideDown) && (toOrientation == UIInterfaceOrientationLandscapeRight))) { } if(((fromOrientation == UIInterfaceOrientationLandscapeLeft) && (toOrientation == UIInterfaceOrientationPortraitUpsideDown)) || ((fromOrientation == UIInterfaceOrientationLandscapeRight) && (toOrientation == UIInterfaceOrientationPortrait))) { } if(((fromOrientation == UIInterfaceOrientationPortrait) && (toOrientation == UIInterfaceOrientationPortraitUpsideDown)) || ((fromOrientation == UIInterfaceOrientationPortraitUpsideDown) && (toOrientation == UIInterfaceOrientationPortrait))) { } if(((fromOrientation == UIInterfaceOrientationLandscapeLeft) && (toOrientation == UIInterfaceOrientationLandscapeRight)) || ((fromOrientation == UIInterfaceOrientationLandscapeRight) && (toOrientation == UIInterfaceOrientationLandscapeLeft))) { } } which seems like a perfectly good waste of code. Furthermore, I was planning on using CGAffineTransform (like cited here: http://www.crystalminds.nl/?p=1102) but I'm confused about whether I should change the view's dimensions to match what they will be after the rotation. The big nightmare here is that you have to keep track of a global "orientation" variable. If you don't, the illusion is lost and the ViewController is rotated into whatever. I could really use some help on this, thanks!
