  • C# WinForms. Multiple Forms in separate threads

    - by Calum Murray
    I'm trying to run an ATM Simulation in C# with Windows Forms that can have more than one instance of an ATM machine transacting with a bank account simultaneously. The idea is to use semaphores/locking to block critical code that may lead to race conditions. My question is this: How can I run two Forms simultaneously on separate threads? In particular, how does all of this fit in with the Application.Run() that's already there? Here's my main class: public class Bank { private Account[] ac = new Account[3]; private ATM atm; public Bank() { ac[0] = new Account(300, 1111, 111111); ac[1] = new Account(750, 2222, 222222); ac[2] = new Account(3000, 3333, 333333); Application.Run(new ATM(ac)); } static void Main(string[] args) { new Bank(); } } ...that I want to run two of these forms on separate threads... public partial class ATM : Form { //local reference to the array of accounts private Account[] ac; //this is a reference to the account that is being used private Account activeAccount = null; private static int stepCount = 0; private string buffer = ""; // the ATM constructor takes an array of account objects as a reference public ATM(Account[] ac) { InitializeComponent(); //Sets up Form ATM GUI in ATM.Designer.cs this.ac = ac; } ... I've tried using Thread ATM2 = new Thread(new ThreadStart(/*What goes in here?*/)); But what method do I put in the ThreadStart constructor, since the ATM form is event-driven and there's no one method controlling it? Thanks, Calum

  • Changing label content programmatically from within a DataTemplate used in a DataGrid column header

    - by iimpact
    I'm dynamically creating DataGrid columns (based on an event from my ViewModel) and programmatically adding them to an existing DataGrid. Each column uses a generic HeaderTemplate by setting it to a DataTemplate that has been identified in the xaml. The DataTemplate contains two labels in which needs their content needs to be changed upon creation of the DataGrid column. How would this be done? I understand that the DataTemplate uses the ContentPresenter but I am having trouble accessing it within a dynamically created DataGrid column. Code is as follows: xaml: (template used to format the DataGrid column header): <DataTemplate x:Key="columnTemplate"> <StackPanel> <Label Padding="0" Name="labelA"/> <Separator HorizontalAlignment="Stretch"/> <Label Padding="0" Name="labelB"/> </StackPanel> </DataTemplate> c#: (used to dynamically create a DataGrid column and add it to an existing DataGrid) var dataTemplate = FindResource("columnTemplate") as DataTemplate; var column = new DataGridTextColumn(); column.HeaderTemplate = dataTemplate; DataGrid1.Columns.Add(column); I would like to then access both labelA and labelB and change the content.

  • iPhone multitouch - Some touches dispatch touchesBegan: but not touchesMoved:

    - by zkarcher
    I'm developing a multitouch application. One touch is expected to move, and I need to track its position. For all other touches, I need to track their beginnings and endings, but their movement is less critical. Sometimes, when 3 or more touches are active, my UIView does not receive touchesMoved: events for the moving touch. This problem is intermittent, and can always be reproduced after a few attempts: Touch the screen with 2 fingers. Touch the screen with another finger, and move this finger around. The moving finger always dispatches touchesBegan: and touchesEnded:, but sometimes does not dispatch any touchesMoved: events. Whenever the moving touch does not dispatch touchesMoved: events, I can force it to dispatch touchesMoved: if I move one of the other touches. This seems to "force" every touch to recheck its position, and I successfully receive a touchesMoved: event. However, this is clumsy. This bug is reproducible on both the iPhone 2G and 3GS models. My question is: How do I ensure that my moving touch dispatches touchesMoved: events? Does anyone have any experience with this issue? I've spent few fruitless days searching the web for answers. I found a post describing how to sync touch events with the VBL: http://www.71squared.com/2009/04/maingameloop-changes/ . However, this has not solved the problem. I really don't know how to proceed. Any help is appreciated!

  • Jquery .hide problem

    - by Sergio
    I'm using jquery to show animated MSN like window at the bottom of the page. Jquery code: $(document).ready(function() { $(" .inner").stop().animate({height:'142px'},{queue:false, duration:600}); $(' .close').click(function(event) { $(' .inner').hide(); }); $(' .inner').click(function() { location.replace("somepage.php"); }); }); The CSS: .close {height:14px; z-index:100; position: absolute; margin-left:174px; margin-top:12px; border:1px solid #F00;} .inner {position:absolute;bottom:0;width:201px;height:117px;right: 0; margin-right:10px; float:left; z-index:-1; display:block; cursor:pointer;} The problem that I have with this code is that the close button (showing at the right top corner of .inner DIV) can't fire Jquery .hide function. Why?

  • Colorbox with bxslider not working

    - by Bill K
    Hello I am trying to use bxslider with colorbox. My implementation of bxslider is like an example listed here. The difference is that I want only the pagers to be shown. Also when the user clicks one pager I want colorbox to open and have next and previous buttons. The problem is that I cant group the images with colorbox and next and previous button is not shown! The following code uses the rel option but with this way colorbox doesnt event start. What I have tried till now is: HTML <div class="slider_mini" style="position:relative;bottom:0px;"> <div id="bx-pager"> <a data-slide-index="0" href="image.jpg" class="imgz"><img style="width:130px;height:104px;" src="image.jpg"/></a> <a data-slide-index="1" href="image2.jpg" class="imgz"><img style="width:130px;height:104px;" src="image2.jpg"/></a> <a data-slide-index="2" href="image3.jpg" class="imgz"><img style="width:130px;height:104px;" src="image3.jpg"/></a> </div> </div> SCRIPT <script type="text/javascript"> $(document).ready(function(){ $('.imgz').colorbox({rel:'imgz'}); $('.bxslider.two').bxSlider({ pagerCustom: '#bx-pager' }); $('#bx-pager').bxSlider({ slideWidth: 130, minSlides: 2, maxSlides: 3, moveSlides: 1, slideMargin: 10 }); }); </script> Not working Fiddle. Feedback: The problem was in live website that I was calling colorbox before bxslider. I put the call after bxslider's and it works. Thank you.

  • Emacs key binding fallback

    - by rejeep
    Hey, I have a minor mode. If that mode is active and the user hits DEL, I want to do some action, but only if some condition holds. If the condition holds and the action is executed I want to do nothing more after that. But if the condition fails, I don't want to do anything and let the default DEL action execute. Not sure how I could solve this. But I guess I could do it in two ways: 1) I could rebind the DEL key to a function in the minor mode and then check if the conditions holds ot not. But then how do I know what the default command to DEL is? 2) I could add a pre command hook like this. Execute the command and then break the chain. But how do I break the chain? (add-hook 'pre-command-hook (lambda() (when (equal last-input-event 'backspace) ;; Do something and then stop (do not execute the ;; command that backspace is bound to) ))) In what way would you solve it? Thanks!

  • Writing a code example

    - by Stefano Borini
    I would like to have your feedback regarding code examples. One of the most frustrating experiences I sometimes have when learning a new technology is finding useless examples. I think an example as the most precious thing that comes with a new library, language, or technology. It must be a starting point, a wise and unadulterated explanation on how to achieve a given result. A perfect example must have the following characteristics: Self contained: it should be small enough to be compiled or executed as a single program, without dependencies or complex makefiles. An example is also a strong functional test if you correctly installed the new technology. The more issues could arise, the more likely is that something goes wrong, and the more difficult is to debug and solve the situation. Pertinent: it should demonstrate one, and only one, specific feature of your software/library, involving the minimal additional behavior from external libraries. Helpful: the code should bring you forward, step by step, using comments or self-documenting code. Extensible: the example code should be a small “framework” or blueprint for additional tinkering. A learner can start by adding features to this blueprint. Recyclable: it should be possible to extract parts of the example to use in your own code Easy: An example code is not the place to show your code-fu skillz. Keep it easy. helpful acronym: SPHERE. Prototypical examples of violations of those rules are the following: Violation of self-containedness: an example spanning multiple files without any real need for it. If your example is a python program, keep everything into a single module file. Don’t sub-modularize it. In Java, try to keep everything into a single class, unless you really must partition some entity into a meaningful object you need to pass around (and java mandates one class per file, if I remember correctly). Violation of Pertinency: When showing how many different shapes you can draw, adding radio buttons and complex controls with all the possible choices for point shapes is a bad idea. You de-focalize your example code, introducing code for event handling, controls initialization etc., and this is not part the feature you want to demonstrate, they are unnecessary noise in the understanding of the crucial mechanisms providing the feature. Violation of Helpfulness: code containing dubious naming, wrong comments, hacks, and functions longer than one page of code. Violation of Extensibility: badly factored code that have everything into a single function, with potentially swappable entities embedded within the code. Example: if an example reads data from a file and displays it, create a method getData() returning a useful entity, instead of opening the file raw and plotting the stuff. This way, if the user of the library needs to read data from a HTTP server instead, he just has to modify the getData() module and use the example almost as-is. Another violation of Extensibility comes if the example code is not under a fully liberal (e.g. MIT or BSD) license. Violation of Recyclability: when the code layout is so intermingled that is difficult to easily copy and paste parts of it and recycle them into another program. Again, licensing is also a factor. Violation of Easiness: Yes, you are a functional-programming nerd and want to show how cool you are by doing everything on a single line of map, filter and so on, but that could not be helpful to someone else, who is already under pressure to understand your library, and now has to understand your code as well. And in general, the final rule: if it takes more than 10 minutes to do the following: compile the code, run it, read the source, and understand it fully, it means that the example is not a good one. Please let me know your opinion, either positive or negative, or experience on this regard.

  • Node.js fetching Twitter Streaming API - EADDRNOTAVAIL

    - by Jordan Scales
    I have the following code written in node.js to access to the Twitter Streaming API. If I curl the URL below, it works. However, I cannot get it to work with my code. var https = require('https'); https.request('https://USERNAME:[email protected]/1.1/statuses/sample.json', function(res) { res.on('data', function(chunk) { var d = JSON.parse(chunk); console.log(d); }); }); But I receive the following node.js:201 throw e; // process.nextTick error, or 'error' event on first tick ^ Error: connect EADDRNOTAVAIL at errnoException (net.js:642:11) at connect (net.js:525:18) at Socket.connect (net.js:589:5) at Object.<anonymous> (net.js:77:12) at new ClientRequest (http.js:1073:25) at Object.request (https.js:80:10) at Object.<anonymous> (/Users/jordan/Projects/twitter-stream/app.js:3:7) at Module._compile (module.js:441:26) at Object..js (module.js:459:10) at Module.load (module.js:348:31) If anyone can offer an alternative solution, or explain to me why this doesn't work, I would be very grateful.

  • Facebook IOS SDK: Error in Publish Story Dialog

    - by lividsquirrel
    I've successfully set up the "DemoApp" project from the Facebook IOS SDK to use my "OKC ThunderCast" Facebook application. I have also configured another "Tester" application from scratch to successfully use the Facebook SDK and publish stories to my news feed. However, in my production application, I always get this result when calling the "dialog" method. The full description of the error message is "Error on line 52 at column 17: Opening and ending tag mismatch: div line 0 and body" Here's a detailed walkthrough of all of my code to make sure nothing is missed. 1) A UIViewController calls the "authorize" method NSArray *fbPerms = [NSArray arrayWithObjects:@"read_stream", @"offline_access", nil]; [[FacebookSingleton sharedInstance].facebook authorize:fbPerms delegate:self]; Note: The FacebookSingleton is a class I wrote that always returns a single instance of the "Facebook" class. I am using it successfully in other applications. 2) Safari is opened and the user is successfully authenticated and authorized 3) The application is called back and the "handleOpenUrl" method is called, which calls the "fbDidLogin" method of the UIViewController - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { Facebook *fb = [FacebookSingleton sharedInstance].facebook; return [fb handleOpenURL:url]; } 4) The same UIViewController handles the "fbDidLogin" event, and calls the "dialog" method - (void)fbDidLogin { [[FacebookSingleton sharedInstance].facebook dialog:@"feed" andDelegate:self]; } I also have the necessary "URL Schemes" and "URL Types" entries in the .plist file. To my eyes, I am using exactly the same code in the "DemoApp", "Tester", and production applications. But while the DemoApp and Tester work, I always see this HTML error in the feed dialog in my production application. Has anyone seen a similar issue? Could it be related to the Facebook "Bundle ID" setting in the Facebook application settings? Is there some build or .plist setting that is different? I have invested a great deal of time into troubleshooting with no success in several weeks. Thanks in advance...

  • iPhone: Proper use of View and View Controller

    - by Joel
    I've recently been doing a lot of Objective-C programming, and just got back into doing more iPhone development. I've done a lot of programming using MVC in other languages/frameworks, but I just want to make sure I'm using MVC properly in my iPhone Development. I created a new iPhone Utility Application, which creates two views: MainView and FlipsideView. Both have a controller (FlipsideViewController and MainViewController) and XIB file of their own. What I've been doing is putting the IBOutlet UIControl myControl variables in my MainView.h or FlipsideView.h files and then tying the controls in Interface Builder to those variables. Then I put any IBAction SomeAction myAction methods in the MainViewController.h and FlipsideViewController.h files and tying the events to those methods in Interface Builder. This seems to be conceptually correct, but seems to cause problems. Say I have a button that when clicked it changes a label's text. So the Controller doesn't have a clue of what the variable name of the label is in the OnTouchUp event handler for my button. So I make a @property for it. But since the MainViewController.view property isn't of type MyView, I get warnings or errors whenever I try to access those properties from the view controller. I am doing this correctly? Is there a better way to do this? If this is correct, how do I properly work with those variables without getting warnings or errors? Thanks

  • [Google Maps] Trouble with invalid argument when switching jQueryUI based tabs

    - by Chad
    Here's a page with the issue To reproduce the error, using IE - click the directions tab, then any of the others. What I'm trying to do is this: On page load, do nothing really. However, when the directions tab loads - setup the map. Like so: $('#tabs').bind('tabsshow', function(event, ui) { if (ui.panel.id == "tabs-5") { // get map for directions var dirMap = new GMap2($("div#dirMap").get(0)); dirMap.setCenter(new GLatLng(35.79648921414565,139.40663874149323), 12); dirMap.enableScrollWheelZoom(); dirMap.addControl(new PanoMapTypeControl()); geocoder = new GClientGeocoder(); $("#dirMap").resizable({ stop: function() { dirMap.checkResize(); } }); // clear dirText $("div#dirMapText").html(""); dirMap.clearOverlays(); var polygon = new GPolygon([new GLatLng(35.724496338474104,139.3444061279297),new GLatLng(35.74748750802863,139.3363380432129),new GLatLng(35.75765724051559,139.34303283691406),new GLatLng(35.76545779822543,139.3418312072754),new GLatLng(35.767547103447725,139.3476676940918),new GLatLng(35.75835374997911,139.34955596923828),new GLatLng(35.755149755962755,139.3567657470703),new GLatLng(35.74679090345495,139.35796737670898),new GLatLng(35.74762682821177,139.36294555664062),new GLatLng(35.744422402303826,139.36346054077148),new GLatLng(35.74860206266584,139.36946868896484),new GLatLng(35.735644401200986,139.36843872070312),new GLatLng(35.73843117306677,139.36174392700195),new GLatLng(35.73592308277646,139.3531608581543),new GLatLng(35.72686543236113,139.35298919677734),new GLatLng(35.724496338474104,139.3444061279297)], "#f33f00", 5, 1, "#ff0000", 0.2);dirMap.addOverlay(polygon); // load directions directions = new GDirections(dirMap, $("div#dirMapText").get(0)); directions.load("from: [email protected],139.37083393335342 to: Ruby [email protected],139.40663874149323"); } }); What the heck is causing the error? The IE javascript debugger claims the error lies in main.js, line 139 character 28. (the google maps api file). Which is this line: function zf(a,b){a=a.style;a.width=b.getWidthString();a.height=b.getHeightString()} Any ideas? Thanks in advance!

  • jQuery Colorbox Iframe and Selector

    - by Joker
    I have this: $("a.money").colorbox({href:$("a.money").attr("href")+" div#content"}); Which opens an overlay but only of the content within the #content selector. If I add iframe:true, this will no longer work. Is there a way to get it to work with an iframe? Edit: The closest I could get it to work was by doing this: $("a.money").colorbox({iframe:true, width:700, height:425, onComplete: function() { alert('test'); $test = $("#cboxLoadedContent iframe").contents().find("#content").html(); $("#cboxLoadedContent iframe").contents().find("#container").html($test); } }); Although without the alert it doesn't appear to work, I looked into that and I think I need to use .live(), which led me to trying this: $('a.money').live('click', function() { url = this.href; // this is the url of the element event is triggered from $.fn.colorbox({href: url, iframe:true,width:700, height:425, onComplete: function() { $test = $("#cboxLoadedContent iframe").contents().find("#content").html(); $("#cboxLoadedContent iframe").contents().find("#container").html($test); } }); return false; }); Didn't work, I still needed to add an alert to make it work. In case you might be wondering what I'm trying to do. The webpage is loaded in the iframe, with all the elements in the #container, so that includes #header, #sidebars, but I only want to show the #content inside the iframe. However, this led me to another problem I realized. Assuming I got this to work without the alert, it will only work for that initial page. For example, if I loaded up a form in the iframe, after submitting the form, I would once again see the whole layout instead of just the #content portion. Is it possible to continue only showing the #content portion of the page upon further navigation?

  • How to access empty ASP.NET ListView.ListViewItem to apply a style after all databinding is done?

    - by Caroline S.
    We're using a ListView with a GroupTemplate to create a three-column navigation menu with six items in each column, filling in two non-data-bound rows in the last column with an EmptyItemTemplate that contains an empty HTML list item. That part works fine, but I also need to programmatically add a CSS class to the sixth (last) item in each column. That part is also working fine for the first two columns because I'm assigning the CSS class in the DataBound event, where I can iterate through the ListView.Items collection and access the sixth item in the first two columns by using a modulus operator and counter. The problem comes in the last column, where the EmptyItemTemplate has correctly filled in two empty list items, to the last of which I also need to add this CSS class. The empty items are not included in the ListView.Items collection (that's just ListViewDataItems, and the empty items are ListViewItems). I cannot find a way to access the entire collection of ListViewItems after binding. Am I missing something? I know I can access the empty items during ItemCreated, but I can't figure out how to determine where the item I'm creating falls in the flow, and whether it's the last one. Any help would be appreciated, if this can even be done -- I'm a bit stuck.

  • jQuery - IF then Remove class on .hover

    - by danit
    I have the following jQuery function: $(function(){ if ($(".menu li").hasClass("active")) { $(".active").css("margin-top", "6px"); } }); This is applied to a CSS/jQuery menu, which expands and contracts when each menu item is hovered over. The onClick event adds a margin-top of 6px to give the impressions of a button depress. I'm then using PHP to detect which page the user is visiting to add an .active class to the relevant menu item. The question, the .active class should remain in place until the user hovers over a different menu item. At which point the .active class should be removed from this element - As the .active class is reused on the .hover events. Here is the basic HTML Markup: <ul id="menu"> <li> <div class="inner"> <div class="button"><img src="images/insightbutton.png" /></div> <div class="description">&nbsp;</div> </div> </li> <li> <div class="inner"> <div class="button"><img src="images/insightbutton.png" /></div> <div class="description">&nbsp;</div> </div> </li> </ul> How can I keep the .active class applied to the active menu item, but remove it when .inner is hovered over?

  • validation control unable to find its control to validate

    - by nat
    i have a repeater that is bound to a number of custom dataitems/types on the itemdatabound event for the repeater the code calls a renderedit function that depending on the custom datatype will render a custom control. it will also (if validation flag is set) render a validation control for the appropriate rendered edit control the edit control overrides the CreateChildControls() method for the custom control adding a number of literalControls thus protected override void CreateChildControls() { //other bits removed - but it is this 'hidden' control i am trying to validate this.Controls.Add(new LiteralControl(string.Format( "<input type=\"text\" name=\"{0}\" id=\"{0}\" value=\"{1}\" style=\"display:none;\" \">" , this.UniqueID , this.MediaId.ToString()) )); //some other bits removed } the validation control is rendered like this: where the passed in editcontrol is the control instance of which the above createchildcontrols is a method of.. public override Control RenderValidationControl(Control editControl) { Control ctrl = new PlaceHolder(); RequiredFieldValidator req = new RequiredFieldValidator(); req.ID = editControl.ClientID + "_validator"; req.ControlToValidate = editControl.UniqueID; req.Display = ValidatorDisplay.Dynamic; req.InitialValue = "0"; req.ErrorMessage = this.Caption + " cannot be blank"; ctrl.Controls.Add(req); return ctrl; } the problem is, altho the validation controls .ControlToValidate property is set to the uniqueid of the editcontrol. when i hit the page i get the following error: Unable to find control id 'FieldRepeater$ctl01$ctl00' referenced by the 'ControlToValidate' property of 'FieldRepeater_ctl01_ctl00_validator'. i have tried changing the literal in the createchildcontrols to a new TextBox(), and then set the id etc then, but i get a similar problem. can anyone enlighten me? is this because of the order the controls are rendered in? ie the validation control is written before the editcontrol? or... anyhow any help much appreciated thanks nat

  • Weird order when painting triangle outlines using GL_LINE_STRIP

    - by RayDeeA
    I'm developing an app for iOS-Plaftorms using OpenGL. Currently I'm having a weird issue when painting a plane (terrain) which consists of multiple subplanes, where each subplane consists of 2 triangles forming a rect. I'm painting this terrain as a wireframe by using a call to glDrawElements and provide the parameters GL_Line_Strip and the precalculated indices. The problem is that the triangles get painted in the wrong order or are rather vertically mirrored. They do not get painted in the order how I specified the indices, which is confusing. This is the simplified code to generate the vertices: for(NSInteger y = - gridSegmentsY / 2; y < gridSegmentsY / 2; y ++) { for(NSInteger x = - gridSegmentsX / 2; x < gridSegmentsX / 2; x ++) { vertices[pos++] = x * 5; vertices[pos++] = y * 5; vertices[pos++] = 0; } } This is how I generate the indices including degenerated ones (To use as IBO). pos = 0; for(int y = 0; y < gridSegmentsY - 1; y ++) { if (y > 0) { // Degenerate begin: repeat first vertex indices[pos++] = (unsigned short)(y * gridSegmentsY); } for(int x = 0; x < gridSegmentsX; x++) { // One part of the strip indices[pos++] = (unsigned short)((y * gridSegmentsY) + x); indices[pos++] = (unsigned short)(((y + 1) * gridSegmentsY) + x); } if (y < gridSegmentsY - 2) { // Degenerate end: repeat last vertex indices[pos++] = (unsigned short)(((y + 1) * gridSegmentsY) + (gridSegmentsX - 1)); } } So in this part... indices[pos++] = (unsigned short)((y * gridSegmentsY) + x); indices[pos++] = (unsigned short)(((y + 1) * gridSegmentsY) + x); ...I'm setting the first index in the indices array to point to the current (x,y) and the next index to (x,y+1). I'm doin' this for all x's in the current strip, then I'm handling degenerated triangles and repeat this procedure for the next strip (y+1). This method is taken from http://www.learnopengles.com/android-lesson-eight-an-introduction-to-index-buffer-objects-ibos/ So I expect the resulting mesh to get painted like: a----b----c | /| /| | / | / | | / | / | |/ |/ | d----e----f | /| /| | / | / | | / | / | |/ |/ | g----h----i by painting it as described using: glDrawElements(GL_LINE_STRIP, indexCount, GL_UNSIGNED_SHORT, 0); ...since I expect GL_Line_Strip to paint first a line from (a-d), then from (d-b), then (b, e)... and so on (as specified in the indices calculation) But what actually gets painted is: *----*----* |\ |\ | | \ | \ | | \ | \ | | \| \| *----*----* |\ |\ | | \ | \ | | \ | \ | | \| \| *----*----* So the triangles are somehow painted in the wrong order and I need to know why? ;). Does somebody know? Does the problem lie in using GL_Line_Strip or is there a bug in my code? My eye is at (0.0f, 0.0f, 20.0f) and looks at (0,0,0). The mesh is painted along the x-axis & y-axis from left to right with z = 0, so the mesh should not be flipped or anything.

  • JQuery Post-Request question - FF doesn't get the result of the referenced php page

    - by OlliD
    Dear community, I just want to have my question posted here but just from the beginning: For a personal web project I use PHP + JQuery. Now I got stuck when I try to use the ajax posting method to send data to another php-page. I planned to have some navigational elements like next + previous on the bottom of the page by saving the user input / user given data. The code looks as follows: <div id="bottom_nav"> <div id="prev" class="flt_l"><a href="?&step=<?= $pages[$step-1] ?>">next</a></div> <div id="next" class="flt_r"><a href="?&step=<?= $pages[$step+1] ?>">previous</a></div> </div> The functionality of the page works fine. Lateron, I use the following code to sent data over via POST: $("#bottom_nav a").click( function() { alert("POST-Link: Parameter=" + $("#Parameter").val()); $.ajax( { type:"post", url:"saveParameter.php", data:"Parameter=" + $("#Parameter").val(), success: function(result) { alert(result); //$("#test").text(result); } }); }); The request itself work perfectly on IE, but on FF I'm not able to get back any result. within the PHP page, there just written: <? echo $_POST['Parameter']; ?> As IE returns the correct value, FF just provide an empty message box. I assumed that the behaviour on the -Link is different. While IE seems to handle the click event after the JS-Code execution, FF will interpret it before. My question was whether you has a solution on this regarding restructuring the code itself or using another method to reach the intened behaviour. Thanks for your assistance and recommendations, Olli

  • Yaml::load_file acting different between development and production (Rails)

    - by James
    Hi, I am completely stumped at the nature of this problem. We export data from our application into a 'cleaned' YAML file (stripping out IDs, created_at etc). Then we (will) allow users to import these files back into the application - it is the import that is completely bugging me out. In development, YAML::load_file(params[:uploaded_data].local_path) returns an array of YAML::Objects's (and it doesn't matter which of the number of different ways the file could be loaded): [#{"exception_count"="0", "title"="Start", "amount"="70.00", "colour"=nil, "repeat_type_id"="0", "repeat_interval"="1"}}, etc etc] Which is very nice, as the attributes also include the (associated model) exceptions that you see an exception_count for. However on production (rails 2.3.2, running REE 1.8.7 and 1.8.6 for testing, tested on two different production env's, and running production locally) it returns an array of the Objects within the YAML - in this case, Event: [#, repeat_type_id: 0, colour: nil, repeat_interval: 1, exception_count: 0, etc etc] Now this would be just perplexing if it also included the associated model Exception with it - however it doesn't. Can anyone at all shed some light on why the Yaml parser would behave so differently between production and development? I'm on rails 2.3.2, running REE 1.8.7; however I've also tested running Ruby 1.8.6 with exactly the same results. Thanks for any help!

  • Flash CS5- Problem with "navigateToURL" in web-browswer hosted on MySpace

    - by NervXT
    I made a quick flash document for my friend who posted it his MySpace. The document has 3 buttons, each with a URL attached to them. When I play the SWF file locally, the links work fine, however once it's published to MySpace, the links refuse to work. The hand icon comes up so it understands them at least as buttons, but it seems to do nothing when clicked in the web-browser. Also, I can open the SWF in my browser and it also works fine. I'm using Flash CS5 and working in ActionScript 3.0. The three buttons are on one layer called "Buttons". I right click the button and click "Actions". From there, I click the "Code Snippets" and under the folder "Actions" there is an item called "Click to Go To Webpage". Here is the code it gives you by default: button_2.addEventListener(MouseEvent.CLICK, fl_ClickToGoToWebPage_6); function fl_ClickToGoToWebPage_6(event:MouseEvent):void { navigateToURL(new URLRequest("http://www.adobe.com"), "_blank"); } I heard there was a problem with MySpace not allowing action scripts, but after checking the source code of the web-page, the values in the "param" code seem to "always" allow action scripts. At any point, I'm lost and not sure what it causing this. I don't think it's a browser issue, since it's working fine when I execute the SWF by itself, and when I load it into Firefox. It's just seems MySpace is having a problem with it. Any advice is appreciated.

  • HttpURLConnection inside a loop

    - by Carlos Garces
    Hi! I'm trying to connect to one URL that I know that exist but I don't know when. I don't have access to this server so I can't change anything to receive a event. The actual code is this. URL url = new URL(urlName); for(int j = 0 ; j< POOLING && disconnected; j++){ HttpURLConnection connection = (HttpURLConnection) url.openConnection(); int status = connection.getResponseCode(); if(status == HttpURLConnection.HTTP_OK || status == HttpURLConnection.HTTP_NOT_MODIFIED){ //Some work }else{ //wait 3s Thread.sleep(3000); } } Java not is my best skill and I'm not sure if this code is good from the point of view of performance. I'm opening a new connection every 3 seconds? or the connection is reused? If I call to disconnect() I ensure that no new connections are open in the loop, but... it will impact in performance?. Suggestions? What is the fast/best ways to know it a URL exist?

  • Detect if certain UIView was touched amongst other UIViews

    - by Rudiger
    HI Guys, Sorry if this has been answered elsewhere but I can't seem to get it to work. I have 3 UIViews, layered on top of one large uiview. I want to know if the user touches the top one and not care about the other ones. I will have a couple of buttons in the second UIView and a UITable in the 3rd UIView. Problem is I turn userInteractionEngabled on on the first view and that works, but all the other views respond in the same way even if I turn it off. If I disable userInteractionEnabled on self.view none of them respond. I also can't detect which view was touched in the touchesBegan delegate method. my code: UIView *aView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 150)]; aView = userInteractionEnabled = YES; [self.view addSubview:aView]; UIView *bView = [[UIView alloc] initWithFrame:CGRectMake(0, 150, 320, 50)]; bView.userInteractionEnabled = NO; [self.view addSubview:bView]; -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { //This gets called for a touch anywhere } Thanks for any help.

  • How do I get my code to read the spaces between longs?

    - by WahtsUpWorld
    I apologize for any inconvenience that may occur in answering my question, I'm fairly new to programming and I'm so far only in the last weeks of my community college Java I class. The problem I am facing is in my code of which I cannot seem to get the PrintWriter to address the spaces in between my longs' phone number and social security I.D. The entire code consists of two classes in which one pulls from the other the information needed to parse and present the file writer/print writer. Here is the entire code w/ the second class after it: public class FinalProjectGroup1 { public static void main(String[] args) { } public String name; public long ssid; public double pay; public String address; public long number; public void cleanUpConstructor() {} public FinalProjectGroup1(String name, String address, double pay, long ssid, long number){ this.name = name; this.pay = pay; this.ssid = ssid; this.address = address; this.number = number; cleanUpConstructor(); } public void setName(String name) { this.name = name; } public String getName() { return name; } public void setPay(double pay) { this.pay = pay; } public double getPay() { return pay; } public void setSSID(long ssid) { this.ssid = ssid; } public long getSSID() { return ssid; } public void setAddress(String address) { this.address = address; } public String getAddress() { return address;
