  • How to disable scrollbars with JavaScript?

    - by Flupkear
    I need to lock the browser scrollbars when I show a div that represent a modal window in Internet Explorer 7 only. Googling I found that I can use document.body.style.overflow='hidden' but this doesn't work for IE7. I also tried with document.body.scroll="no" which works but only after I mouse over the scrollbar :-S Does anybody knows a better aproach? Thansks

  • PayPal IPN on port other than 80

    - by Ian Silber
    As anybody tried using Paypal's IPN on a port other than 80? I'm trying to specify a URL like http://domain.com:8080/url/to/ipn.php but the IPN request isn't getting through. If I hit the URL directly from my browser it works fine.

    Quick question: what is the (full) valid / allowed charset for id and class CSS identifiers? Is there a regular expression that I can use to validate against? Is it browser agnostic?

  • Async file uploads in Firefox reset on any DOM change

    - by Vibhu
    I'm pretty sure this is a Firefox or flash-related bug, but I just want to check if anyone has ran into this problem or knows how to fix it. Basically, we have a multi-file upload widget for our highly dynamic web app (think Gmail). We've tried both uploadify for jQuery, and YUI uploader. We've also tried taking those out of our app interface and putting them in an iFrame. What happens is that in the event of any DOM manipulation, even if the uploader is in an iFrame, be it a tab change (in our web app) that covers the iframe temporarily, or a block, etc., the uploader will stop its current upload. In the case of YUI uploader, it fires the "contentReady" event again. This ONLY happens in Firefox. IE and Chrome are fine. In case you are wondering, we really don't have any custom needs here. Just need to have multi-upload file support, and we need to give people free reign to tab around in our interface while an upload is in progress. It seems like Yahoo! and Gmail have both solved this problem. How? What are we doing wrong?

  • Android::Webview removes scrollbar for a DIV

    - by Legend
    I made a small webpage with a scrollable div. When I load it in a browser, it works fine. But when I load it in a webview inside Android, it doesn't let me scroll the div. Is there a workaround for this or do I have to use a different design? I am talking about websites like this.

  • CSS formatter NOT based on CSS Tidy?

    - by Abdu
    I can't find a css formatter (web based or Windows app) which formats the css where it puts the open brace on its own line aligned with its close brace, plus indents the attributes. The web based css formatters out here seem to be based on CSSTidy which doesn't do what I want. I don't like this CSSTidy format: .example { font-size: 3em; } I want: .example { font-size: 3em; }

    Hello, Does anyone know of a good javascript DOM ready library that I can use without loading an entire framework? I found one on google code that seems to work, but the library was posted in 2008 and I can't find any confirmation on up-to-date cross browser support. Thanks, Brian

  • Does visibility affect DOM manipulation performance?

    - by Chetan Sastry
    IE7/Windows XP I have a third party component in my page that does a lot of DOM manipulation to adjust itself each time the browser window is resized. Unfortunately I have little control of what it does internally and I have optimized everything else (such as callbacks and event handlers) as much as I can. I can't take the component off the flow by setting display:none because it fails measuring itself if I do so. In general, does setting visibility of the container to invisible during the resize help improve DOM rendering performance?

  • How do I access variable values from one view controller in another?

    - by Thomas
    Hello all, I have an integer variable (time) in one view controller whose value I need in another view controller. Here's the code: MediaMeterViewController // TRP - On Touch Down event, start the timer -(IBAction) startTimer { time = 0; // TRP - Start a timer timer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(updateTimer) userInfo:nil repeats:YES]; [timer retain]; // TRP - Retain timer so it is not accidentally deallocated } // TRP - Method to update the timer display -(void)updateTimer { time++; // NSLog(@"Seconds: %i ", time); if (NUM_SECONDS == time) [timer invalidate]; } // TRP - On Touch Up Inside event, stop the timer, decide stress level, display results -(IBAction) btn_MediaMeterResults { [timer invalidate]; NSLog(@"Seconds: %i ", time); ResultsViewController *resultsView = [[ResultsViewController alloc] initWithNibName:@"ResultsViewController" bundle:nil]; [self.view addSubview:resultsView.view]; } And in ResultsViewController, I want to process time based on its value ResultsViewController - (void)viewDidLoad { if(time < 3) {// Do something} else if ((time > 3) && (time < 6)) {// Do something else} //etc... [super viewDidLoad]; } I'm kind of unclear on when @property and @synthesize is necessary. Is that the case in this situation? Any help would be greatly appreciated. Thanks! Thomas

  • How to dispatch a new property value in an object to the same property of two other objects

    - by WPFadvocate
    In WPF, I've three objects exposing the same DependencyProperty (let's say it's an integer). I want all three property values to remain synchronized, i.e. that whenever the int value changes in an object, this value is propagated to the two other objects. I think of multibinding to do the job, but I don't know how to detect which object changed, thus which value should be used and propagated to the other objects. Edited: here is my tentative code for multibinding, with the false hope that it would work without additional code: // create the multibinding MultiBinding mb = new MultiBinding() { Mode = BindingMode.TwoWay, UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged }; // create individual bindings to associate object_2 and object_3 to object_1 Binding b2 = new Binding() { Source = object_2, Path = new PropertyPath("X") }; Binding b3 = new Binding() { Source = object_3, Path = new PropertyPath("X") }; // add individual bindings to multibinding mb.Bindings.Add(b2); mb.Bindings.Add(b3); // bind object_2 and _3 to object_1 BindingOperations.SetBinding(object_1, TypeObject_1.XProperty, mb); But actually, there is a runtime error, saying the binding set by the last instruction is lacking a converter. But again I don't know how to write this converter (there is nothing to convert (as this is the case in the related MS sample of code linking 3 rgb properties to a color property), only to forward the value of the property changed to the two other properties). I understand I could solve the problem by creating an X_Changed event in the 3 types and then have each object registering to the two other objects event. I don't like this "manual" way and would prefer to bind the 3 properties together.

  • Is there a way to get SSL certificate details using JavaScript?

    - by sHz
    Hi all, I'd like to gather certain details of an SSL certificate on a particular web-site. I know this is straightforward using the openssl tool on Linux/MacOSX. However is the same or similar possible in JavaScript? I understand that the browser handles socket connections and that the SSL handshake occurs prior to any party sending data. However in an XMLHTTPRequest, I'd like to know if its possible to get these details as some sort of response code etc?

  • .NET Setting a cookie in a WebBrowser control

    - by ty
    I am loading a website using a WebBrowser's Navigate function, and I want the browser to load the page with a cookie I've given it. The following code doesn't work: wb.Navigate(url, null, null, "Cookie: " + cookie + "\n"); What am I doing wrong? Will I have to use InternetSetCookie? This doesn't seem like the best solution. Thanks!

  • Dynamic Google Maps API InfoWindow HTML Content

    - by Peter Hanneman
    I am working in Flash Builder 4 with Google Map's ActionScript API. I have created a map, loaded some custom markers onto it and added some MouseEvent listeners to each marker. The trouble comes when I load an InfoWindow panel. I want to dynamically set the htmlContent based off of information stored in a database. The trouble is that this information can change every couple of seconds and each marker has a unique data set so I can not statically set it at the time I actually create the markers. I have a method that will every minute or so load all of the records from my database into an Object variable. Everything I need to display in the htmlContent is contained in this object under a unique identifier. The basic crux of the problem is that there is no way for me to uniquely identify an info window, so I can not determine what information to pull into the panel. marker.addEventListener(MapMouseEvent.ROLL_OVER, function(e:MapMouseEvent):void { showInfoWindow(e.latLng) }, false, 0, false); That is my mouse event listener. The function I call, "showInfowindow" looks like this: private function showInfoWindow(latlng:LatLng):void { var options:InfoWindowOptions = new InfoWindowOptions({title: appData[*I NEED A UNIQUE ID HERE!!!*].type + " Summary", contentHTML: appData[*I NEED A UNIQUE ID HERE!!!*].info}); this.map.openInfoWindow(latlng, options); } I thought I was onto something by being able to pass a variable in my event listener declaration, but it simply hates having a dynamic variable passed through, it only returns the last value use. Example: marker.addEventListener(MapMouseEvent.ROLL_OVER, function(e:MapMouseEvent):void { showInfoWindow(e.latLng, record.unit_id) }, false, 0, false); That solution is painfully close to working. I iterate through a loop to create my markers when I try the above solution and roll over a marker I get information, but every marker's information reflects whatever information the last marker created had. I apologize for the long explaination but I just wanted to make my question as clear as possible. Does anyone have any ideas about how to patch up my almost-there-solution that I posted at the bottom or any from the ground up solutions? Thanks in advance, Peter Hanneman

  • Loading XML from Web Service

    - by Lukasz
    I am connecting to a web service to get some data back out as xml. The connection works fine and it returns the xml data from the service. var remoteURL = EveApiUrl; var postData = string.Format("userID={0}&apikey={1}&characterID={2}", UserId, ApiKey, CharacterId); var request = (HttpWebRequest)WebRequest.Create(remoteURL); request.Method = "POST"; request.ContentLength = postData.Length; request.ContentType = "application/x-www-form-urlencoded"; // Setup a stream to write the HTTP "POST" data var WebEncoding = new ASCIIEncoding(); var byte1 = WebEncoding.GetBytes(postData); var newStream = request.GetRequestStream(); newStream.Write(byte1, 0, byte1.Length); newStream.Close(); var response = (HttpWebResponse)request.GetResponse(); var receiveStream = response.GetResponseStream(); var readStream = new StreamReader(receiveStream, Encoding.UTF8); var webdata = readStream.ReadToEnd(); Console.WriteLine(webdata); This prints out the xml that comes from the service. I can also save the xml as an xml file like so; TextWriter writer = new StreamWriter(@"C:\Projects\TrainingSkills.xml"); writer.WriteLine(webdata); writer.Close(); Now I can load the file as an XDocument to perform queries on it like this; var data = XDocument.Load(@"C:\Projects\TrainingSkills.xml"); What my problem is that I don't want to save the file and then load it back again. When I try to load directly from the stream I get an exception, Illegal characters in path. I don't know what is going on, if I can load the same xml as a text file why can't I load it as a stream. The xml is like this; <?xml version='1.0' encoding='UTF-8'?> <eveapi version="2"> <currentTime>2010-04-28 17:58:27</currentTime> <result> <currentTQTime offset="1">2010-04-28 17:58:28</currentTQTime> <trainingEndTime>2010-04-29 02:48:59</trainingEndTime> <trainingStartTime>2010-04-28 00:56:42</trainingStartTime> <trainingTypeID>3386</trainingTypeID> <trainingStartSP>8000</trainingStartSP> <trainingDestinationSP>45255</trainingDestinationSP> <trainingToLevel>4</trainingToLevel> <skillInTraining>1</skillInTraining> </result> <cachedUntil>2010-04-28 18:58:27</cachedUntil> </eveapi> Thanks for your help!

  • ASP.NET Client to Server communication

    - by Nelson
    Can you help me make sense of all the different ways to communicate from browser to client in ASP.NET? I have made this a community wiki so feel free to edit my post to improve it. Specifically, I'm trying to understand in which scenario to use each one by listing how each works. I'm a little fuzzy on UpdatePanel vs CallBack (with ViewState): I know UpdatePanel always returns HTML while CallBack can return JSON. Any other major differences? ...and CallBack (without ViewState) vs WebMethod. CallBack goes through most of the Page lifecycle, WebMethod doesn't. Any other major differences? IHttpHandler Custom handler for anything (page, image, etc.) Only does what you tell it to do (light server processing) Page is an implementation of IHttpHandler If you don't need what Page provides, create a custom IHttpHandler If you are using Page but overriding Render() and not generating HTML, you probably can do it with a custom IHttpHandler (e.g. writing binary data such as images) By default can use the .axd or .ashx file extensions -- both are functionally similar .ashx doesn't have any built-in endpoints, so it's preferred by convention Regular PostBack (System.Web.UI.Page : IHttpHandler) Inherits Page Full PostBack, including ViewState and HTML control values (heavy traffic) Full Page lifecycle (heavy server processing) No JavaScript required Webpage flickers/scrolls since everything is reloaded in browser Returns full page HTML (heavy traffic) UpdatePanel (Control) Control inside Page Full PostBack, including ViewState and HTML control values (heavy traffic) Full Page lifecycle (heavy server processing) Controls outside the UpdatePanel do Render(NullTextWriter) Must use ScriptManager If no client-side JavaScript, it can fall back to regular PostBack with no JavaScript (?) No flicker/scroll since it's an async call, unless it falls back to regular postback. Can be used with master pages and user controls Has built-in support for progress bar Returns HTML for controls inside UpdatePanel (medium traffic) Client CallBack (Page, System.Web.UI.ICallbackEventHandler) Inherits Page Most of Page lifecycle (heavy server processing) Takes only data you specify (light traffic) and optionally ViewState (?) (medium traffic) Client must support JavaScript and use ScriptManager No flicker/scroll since it's an async call Can be used with master pages and user controls Returns only data you specify in format you specify (e.g. JSON, XML...) (?) (light traffic) WebMethod Class implements System.Web.Service.WebService HttpContext available through this.Context Takes only data you specify (light traffic) Server only runs the called method (light server processing) Client must support JavaScript No flicker/scroll since it's an async call Can be used with master pages and user controls Returns only data you specify, typically JSON (light traffic) Can create instance of server control to render HTML and sent back as string, but events, paging in GridView, etc. won't work PageMethods Essentially a WebMethod contained in the Page class, so most of WebMethod's bullet's apply Method must be public static, therefore no Page instance accessible HttpContext available through HttpContext.Current Accessed directly by URL Page.aspx/MethodName (e.g. with XMLHttpRequest directly or with library such as jQuery) Setting ScriptManager property EnablePageMethods="True" generates a JavaScript proxy for each WebMethod Cannot be used directly in user controls with master pages and user controls Any others?

  • Threadsafe binding with DispatcherObject.CheckAccess()

    - by maffe
    Hi, according to this, I can achieve threadsafety with large overhead. I wrote the following class and use it. It works fine. public abstract class BindingBase : DispatcherObject, INotifyPropertyChanged, INotifyPropertyChanging { private string _displayName; private const string NameDisplayName = "DisplayName"; /// /// The display name for the gui element which bound this instance. It can be used for localization. /// public string DisplayName { get { return _displayName; } set { NotifyPropertyChanging(NameDisplayName); _displayName = value; NotifyPropertyChanged(NameDisplayName); } } protected BindingBase() {} protected BindingBase(string displayName) { DisplayName = displayName; } public event PropertyChangedEventHandler PropertyChanged; public event PropertyChangingEventHandler PropertyChanging; protected void NotifyPropertyChanged(string name) { if (PropertyChanged == null) return; if (CheckAccess()) PropertyChanged.Invoke(this, new PropertyChangedEventArgs(name)); else Dispatcher.BeginInvoke(DispatcherPriority.Normal, (Action) (() = NotifyPropertyChanged(name))); } protected void NotifyPropertyChanging(string name) { if (PropertyChanging == null) return; if (CheckAccess()) PropertyChanging.Invoke(this, new PropertyChangingEventArgs(name)); else Dispatcher.BeginInvoke(DispatcherPriority.Normal, (Action) (() = NotifyPropertyChanging(name))); } } So is there a reason, why I've never found something like that? Are there any issues I should be aware off? Regards
