  • Cocoa Touch - Display an Activity Indicator while loading a UITabBar View

    - by Aurum Aquila
    I have a UITabBar Application with two views that load large amounts of data from the web in their "viewWillAppear" methods. I want to show a progress bar or an activity indicator while this data is being retrieved, to make sure the user knows the app isn't frozen. I am aware that this has been asked before. I simply need some clarification on what seems to be a rather good solution. I have implimented the code in the example. The question's original asker later solved their problem, by putting the retrieval of data into another "thread". I understand the concept of threads, but I do not know how I would impliment this. With research, I have found that I need to move all of my heavy data retrieval into a background thread, as all of the UI updating occurs in the main thread. If one would be so kind as to provide an example for me, I would be very appreciative. I can provide parts of my existing code as necessary.

  • show activity indicator while loading ViewController

    - by Crystal
    I have a ViewController that takes time to load its views. When I run Instruments, I see from the home screen, if I tap on the icon that pushes that view controller onto the stack, it's half laying out the views, and half getting the data for the views. I tried adding an activity indicator to display on the home screen over the button when the button is pressed to push the LongRunningViewController onto the stack. So I basically do this: - (IBAction)puzzleView:(id)sender { dispatch_async(dispatch_get_main_queue(), ^{ [self.activityIndicator startAnimating]; }); PuzzleViewController *detailViewController = [[[PuzzleViewController alloc] init] autorelease]; [self.navigationController pushViewController:detailViewController animated:YES]; [self.activityIndicator stopAnimating]; }

Can I achieve this in a for loop or i need to use some thing else. Regards

  • jQuery to hide and show divs with an indicator

    - by songdogtech
    Using the jQuery below to toggle the hiding and showing of divs of text: how would I add some sort of indicator - like an up and down arrow as a graphic - to the titles when the divs are either open and closed? What's the best way to do that? Two images? A CSS sprite? And most importantly: how would that be integrated into the JS? I've looked at other jQuery that assigns a random number to each div and then determines which are open and which are closed and toggles one of two images. But I'm using php in a WordPress loop to show a posts, and that gives problems with incrementing in the loop, so there must be an easier way that doesn't require changes in the name of the title div. Thanks.... This JS fires the showing and hiding. Each div can be expanded and collapsed independently. $(document).ready(function() { $('div.demo-show:eq(0)> div').hide(); $('div.demo-show:eq(0)> h3').click(function() { $(this).next().slideToggle('fast'); }); }); This is the HTML it works with: <div class="collapser"> <p class="title">Header-1 </p> <div class="contents">Lorem ipsum</div> <p class="title">Header-2</p> <div class="contents">Lorem ipsum </div> <p class="title">Header-3</p> <div class="contents">Lorem ipsum</div> </div> The CSS is arbitrary: .collapser { margin: 0; padding: 0; width: 500px; } .title { margin: 1px; color: #fff; padding: 3px 10px; cursor: pointer; position: relative; background-color:#c30; } .contents { padding: 5px 10px; background-color:#fafafa; }

  • Iphone - UIView not displayed

    - by Raphael Pinto
    Hi, I have a strange problem with a UIView : I want to show an Activity Indicator View that I created with Interface Builder to indicate long running activity. In the viewDidLoad function of my principal viewController I init the ActivityIndicator View like this : - (void)viewDidLoad { [super viewDidLoad]; appDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate]; load = [[ActivityIndicatorViewController alloc] init]; ... When I push a button it call this IBAction : - (IBAction)LaunchButtonPressed{ // Show the Activity indicator view. [self.view addSubview:load.view]; // eavy work [self StartWorking]; // Hide the loading view. [load.view removeFromSuperview]; } In the StartWorking function, I ask a request to an internet serveur and parse the XML file that it return me. The problem is that if I Call my StartWorking function, the application do not start by showing the Activity Indicator view but with the StartWorking function. Whereas if I remove the call to StartWorking function, the view is shown. Is someone able to explain me why? :s

  • JQuery form sticks with the ajax indicator on and won't submit

    - by Steven Buick
    Hi, I'm using JQuery 1.3 to validate and submit a form to a PHP page which JSON encodes a server response to display on the original form page. I've tried submitting the form without the JQuery part and everything seems to work fine but when I add JQuery it doesn't submit and constantly displays the ajax indicator. Here's my code: $(document).ready(function(){ var options = { target: '#messagebox', url: 'updateregistration.php', type:'POST', beforeSubmit: validatePassword, success: processJson, dataType: 'json' }; $("form:not(.filter) :input:visible:enabled:first").focus(); $("#webmailForm").validate({ errorLabelContainer: "#messagebox", rules: { forename: "required", surname: "required", currentpassword: "required", directemail: { required: true, email: true }, directtelephone: "required" }, messages: { forename: { required: "Please enter your forename" }, directemail: { required: "Please enter your direct e-mail address", email: "Your e-mail address does not appear to be valid(Example: [email protected])" }, surname: { required: "Please enter your surname" }, directtelephone: { required: "Please enter your direct telephone number" }, currentpassword: { required: "Please enter your current password" } } }); $('#webmailForm').submit(function() { $('#ajaxindicator').show(); $(this).ajaxSubmit(options); return false; }); }); function processJson(data) { $("#webmailForm").fadeOut("fast"); $("#messagebox").fadeIn("fast"); $("#messagebox").css({'background-image' : 'url(../images/messageboxbackgroundgreen.png)','border-color':'#009900','border-width':'1px','border-style':'solid'}); var forename=data.forename; var surname=data.surname; var directemail=data.directemail; var directphone=data.directphone; var dateofbirth=data.dateofbirth; var companyname=data.companyname; var fulladdress=data.fulladdress; var telephone=data.telephone; var fax=data.fax; var email=data.email; var website=data.website; var fsanumber=data.fsanumber; var membertype=data.membertype; var network=data.network; $("#messagebox").html('<h3>Registration Update successful!</h3>' + '<p><strong>Member Type:</strong> ' + membertype + '<br>' + '<strong>Forename:</strong> ' + forename + '<br><strong>Surname:</strong> ' + surname + '<br><strong>Direct E-mail:</strong> ' + directemail + '<br><strong>Direct Phone:</strong> ' + directphone + '<br><strong>Date of Birth:</strong> ' + dateofbirth + '<br><strong>Company:</strong> ' + companyname + '<br><strong>Address:</strong> ' + fulladdress + '<br><strong>Telephone:</strong> ' + telephone + '<br><strong>Fax:</strong> ' + fax + '<br><strong>E-mail:</strong> ' + email + '<br><strong>Website:</strong> ' + website + '<br><strong>FSA Number:</strong> ' + fsanumber + '<br><strong>Network:</strong> ' + network + '</p>'); $('#ajaxindicator').hide(); } function validatePassword(){ var clientpassword=$("#clientpassword").val(); var currentpassword=$("#currentpassword").val(); var currentpasswordmd5=hex_md5(currentpassword); if (currentpasswordmd5!=clientpassword){ $("#messagebox").html("You input the wrong current password, please try again."); $('#ajaxindicator').hide(); return false; } } I have a disabled textbox and some hidden ones. Could this be the problem?

  • How do I make my volume indicator operate in decibels instead of percentage?

    - by ethana2
    When I want to adjust the volume of anything I'm doing, I find that using the volume controls built into Ubuntu is little but confusion. When the volume is around 100%, dropping it several increments has almost no effect on apparent volume, but when it's around 0%, the effect of one click of my mouse wheel is probably a good 3 decibels. I have observed this behavior on tens of different UC's, since I convert about one Ubuntu user a month (NE team contact). This has proven so frustrating to me that I tend to use the volume knob on my guitar amp ( mono audio :| ) instead of the volume indicator. What can I do to make my volume indicator behave properly until this is fixed? I want each volume increment to be one half or one third decibel. Is there a different piece of software I should use for system volume configuration perhaps?

  • Preventing browser loading indicator with Chrome + GWT-rpc.

    - by Jeeyoung Kim
    Hello. I'm writing a ajax chatting webapp, just to test working with GWT. To simulate server side push of chat messages from the server to the browser, I have a XHR request running behind. It all works fine - except on Chrome, the browser is displaying a loading icon (a spinner) because of the XHR request on background. Is there any way to avoid this? I've tested it in Firefox, and it doesn't display such behavior.

  • Client Side Development - In Process/Completed Indicator Preferences?

    - by Brian
    Hello, I have been doing more client-side development, managing the UI on the client and submitting data to the server via web service calls. I'm not looking for implementation details, but was curious on developer preferences for displaying an operation in process and what to display when completed or even failed. As a for instance, just for clarification sake, what if you are submitting a profile form's data to a web service. I want to display that something's happening to the user, and give them a message that the form submitted successfully. I've in the past used a twitter-style message (that appears at the top), modal dialogs... I was curious what worked for others and any advice (what did the users like/not like, etc.). Again, technical details aren't needed. Thanks.

  • detail disclosure indicator on UIButton

    - by Ben Collins
    Is there a simple way to place a detail disclosure icon on a UIButton? I'm using a navigation controller and I want a button press to push a new view on the stack, so I thought a detail disclosure icon would be appropriate, but I haven't found a straightforward way to do that yet.

  • Has ordinal index of functions in Windows API dlls ever changed?

    - by Panda
    You know that functions in a dll can be imported either by name or by ordinal index. From wikipedia: For most Windows API functions only the names are preserved across different Windows releases; the ordinals are subject to change. Thus, one cannot reliably import Windows API functions by their ordinals. My Question: I know these ordinals MAY CHANGE, but I want to know if they've ever ACTUALLY CHANGED. (Especially about kernel32 & user32 dlls) Why I'm asking this? I heard some viruses do import win32 functions by ordinal. I want to catch them, and I want to know whether I can test for an ordinal number or not. Thanks.

I simply have to load a clients external page into an IFRAME, but I want to use jquery ui to present the loading image while it's grabbing the external data. Simple yes, but I've seen pieces of this not the whole thing.

  • Is there a standard format string in ASP.NET to convert 1/2/3/... to 1st/2nd/3rd...?

    - by Dr. Monkey
    I have an integer in an Access database, which is being displayed in ASP.NET. The integer represents the position achieved by a competitor in a sporting event (1st, 2nd, 3rd, etc.), and I'd like to display it with a standard suffix like 'st', 'nd', 'rd' as appropriate, rather than just a naked number. An important limitation is that this is for an assignment which specifies that no VB or C# code be written (in fact it instructs code behind files to be deleted entirely). Ideally I'd like to use a standard format string if available, otherwise perhaps a custom string (I haven't worked with format strings much, and this isn't high enough priority to dedicate significant time to*, but I am very curious about whether there's a standard string for this). (* The assignment is due tonight, and I've learned the hard way that I can't afford to spend time on things that don't get the marks, even if they irk me significantly.)

  • How to remove keyboard icon from keyboard layout indicator (to leave just the language abbr. alone)?

    - by Ivan
    I'd like to remove a keyboard icon, so replacing "[###] USA" as keyboard layout indicator to just "En", an English or American flag, or "USA" at least. How can I achieve this? UPDATE: When I've clicked to remove e-mail icon from the bar, keyboard language indication has disappeared also, and now I only see that useless keyboard icon, and don't see what language is selected now :-( I use Ubuntu 10.10.

  • Querying using table-valued parameter

    - by antmx
    I need help please with writing a sproc, it takes a table-valued parameter @Locations, whose Type is defined as follows: CREATE TYPE [dbo].[tvpLocation] AS TABLE( [CountryId] [int] NULL, [ResortName] [nvarchar](100) NULL, [Ordinal] [int] NOT NULL, PRIMARY KEY CLUSTERED ( [Ordinal] ASC )WITH (IGNORE_DUP_KEY = OFF) ) @Locations will contain at least 1 row. Each row WILL have a non-null CountryId, and MAY have a non-null ResortName. Each row will have a unique Ordinal, the first being 0. The combinations of CountryId and ResortName in @Locations will be unique. The sproc needs to search against the following table structure. The image can be seen better by right-clicking it and View Image, or similar depending on your browser. Now this is where I'm stuck, the sproc should be able to find Tours where: The Tour's 1st TourHotel (Ordinal 0) has the same CountryId (and ResortName if specified) of the 1st row of @Locations (Ordinal 0). And also if @Locations has 1 row, the Tour must have additional TourHotels, ALL of which must be in the remaining CountryIds (and ResortNames if specified) of these remaining @Locations rows. Edit This is the code I finally used, based on Anthony Faull's suggestion. Thank you so much Anthony: select distinct T.Id from tblTour T join tblTourHotel TH on TH.TourId = T.Id join tblHotel H ON H.Id = TH.HotelId JOIN @Locations L ON ( ( L.Ordinal = 0 AND TH.Ordinal = 0 ) OR ( L.Ordinal > 0 AND TH.Ordinal > 0 ) ) AND L.CountryId = H.CountryId AND ( L.ResortName = H.ResortName OR L.ResortName IS NULL ) cross apply( select COUNT(TH2.Id) AS [Count] FROM tblTourHotel TH2 where TH2.TourId = TH.TourId ) TourHotelCount where TourHotelCount.[Count] = @LocationCount group by T.Id, T.TourRef, T.Description, T.DepartureDate, T.NumNights, T.DepartureAirportId, T.DestinationAirportId, T.AirlineId, T.FEPrice having COUNT(distinct TH.Id) = @LocationCount

  • Can I install 12.04 packages on 11.10?

    - by Jason R
    I'm running 11.10 and am trying to apply the fix to this bug in Empathy, shown at the very bottom. There is an updated package for the offending component available in the Precise repository, and someone even posted a backported .deb package for use on Oneiric. However, when I try to install that package, it seems to have a dependency on a package that isn't available for Oneiric: (Reading database ... 254452 files and directories currently installed.) Preparing to replace telepathy-indicator 0.0.7-0ubuntu1 (using telepathy-indicator_0.1.1-0ubuntu1_amd64.deb) ... Unpacking replacement telepathy-indicator ... dpkg: dependency problems prevent configuration of telepathy-indicator: telepathy-indicator depends on libunity9 (>= 3.4.6); however: Package libunity9 is not installed. dpkg: error processing telepathy-indicator (--install): dependency problems - leaving unconfigured Errors were encountered while processing: telepathy-indicator The person who posted the backported telepathy-indicator package indicated that it depends upon libunity-dev-5.0; the latest version in the Oneiric repositories is a 4.0 vintage. I also can't find a libunity9 available for Oneiric, so I'm wondering: is it possible to just add the Precise repository to my list and pull the updated packages from there, or should I not expect that they would operate correctly?

  • Why is the pavucontrol level indicator jumping while nothing plays?

    - by EnterTheLiquidToasterFamily
    The level indicator in the screenshot does jump around even if nothing is playing. The indicator also reasonably represents sound levels when music is playing. I dont have any mediaservers running or noisy browsertabs open. Also no mic connected. When I turn the volume to max in software and on the amp, there is no noise from the speakers at all. Played music is loud and not distorted. Hardware: Realtek ALC889 over optical audio connector to a generic amp. Software: Debian Wheezy with latest backport kernel 3.14 (same thing on wheezy 3.2 stock), wheezy pulseaudio, xfce session, a custom asound.conf that enables pulseaudio to push sound over optical port. /etc/asound.conf pcm.a52 { @args [CARD] @args.CARD { type string } type rate slave { pcm { type a52 bitrate 448 channels 6 card $CARD } rate 48000 #required somehow, otherwise nothing happens in PulseAudio } }

  • Can a Generic Method handle both Reference and Nullable Value types?

    - by Adam Lassek
    I have a series of Extension methods to help with null-checking on IDataRecord objects, which I'm currently implementing like this: public static int? GetNullableInt32(this IDataRecord dr, int ordinal) { int? nullInt = null; return dr.IsDBNull(ordinal) ? nullInt : dr.GetInt32(ordinal); } public static int? GetNullableInt32(this IDataRecord dr, string fieldname) { int ordinal = dr.GetOrdinal(fieldname); return dr.GetNullableInt32(ordinal); } and so on, for each type I need to deal with. I'd like to reimplement these as a generic method, partly to reduce redundancy and partly to learn how to write generic methods in general. I've written this: public static Nullable<T> GetNullable<T>(this IDataRecord dr, int ordinal) { Nullable<T> nullValue = null; return dr.IsDBNull(ordinal) ? nullValue : (Nullable<T>) dr.GetValue(ordinal); } which works as long as T is a value type, but if T is a reference type it won't. This method would need to return either a Nullable type if T is a value type, and default(T) otherwise. How would I implement this behavior?
