  • implementing UIActivityIndicatorView while NSData dataWithContentsOfURL is downloading

    - by padatronic
    Hi people, I am downloading an mp3 using NSData dataWithContentsOfURL:url. This takes a while and while the file is downloading the application hangs. I want to handle well and ideal would like to show the download progress but can't find methods for this.

So my question really is please could someone tell me what the best way to handle this is? Thanks so much

  • Delphi and prevent event handling

    - by pKarelian
    How do you prevent a new event handling to start when an event handling is already running? I press a button1 and event handler start e.g. slow printing job. There are several controls in form buttons, edits, combos and I want that a new event allowed only after running handler is finnished. I have used fRunning variable to lock handler in shared event handler. Is there more clever way to handle this? procedure TFormFoo.Button_Click(Sender: TObject); begin if not fRunning then try fRunning := true; if (Sender = Button1) then // Call something slow ... if (Sender = Button2) then // Call something ... if (Sender = Button3) then // Call something ... finally fRunning := false; end; end;

  • Unable to launch the ASP.NET Development server because port '1900' is in use.

    - by Shaul
    I don't know what has got into my computer today. I was developing just fine in VS 2008 and testing my ASP.NET web site on my development server. Then suddenly, out of the blue, I can't run my web site any more! As soon as I hit F5, the message appears: Unable to launch the ASP.NET Development server because port '1900' is in use. And it doesn't matter what port I change to, it's always in use! AAARRRGGGHH!!! I have tried: Changing the port number Restarting Visual Studio Rebooting my machine Installing IIS Clue: My IIS refuses to start. But I didn't have IIS installed when I was happily working earlier, so that is probably not the issue; it might just be highlighting something else... Thanks in advance... Update: after rebooting, IIS does start, but the problem here persists.

  • Javascript, AJAX, Extend PHP Session Timeout, Bank Timeout

    - by Guhan Iyer
    Greetings, I have the following JS code: var reloadTimer = function (options) { var seconds = options.seconds || 0, logoutURL = options.logoutURL, message = options.message; this.start = function () { setTimeout(function (){ if ( confirm(message) ) { // RESET TIMER HERE $.get("renewSession.php"); } else { window.location.href = logoutURL; } }, seconds * 1000); } return this; }; And I would like to have the timer reset where I have the comment for RESET TIMER HERE. I have tried a few different things to no avail. Also the code calling this block is the following: var timer = reloadTimer({ seconds:20, logoutURL: 'logout.php', message:'Do you want to stay logged in?'}); timer.start(); The code may look familiar as I found it on SO :-) Thanks!

  • Date object to Calendar [Java]

    - by Samuel
    Hello World, I have a class Movie in it i have a start Date, a duration and a stop Date. Start and stop Date are Date Objects (private Date startDate ...) (It's an assignment so i cant change that) now i want to automatically calculate the stopDate by adding the duration (in min) to the startDate. By my knowledge working with the time manipulating functions of Date is deprecated hence bad practice but on the other side i see no way to convert the Date object to a calendar object in order to manipulate the time and reconvert it to a Date object. Is there a way? And if there is what would be best practice Thanks in advance Samuel

  • learning inkscape for webapp/website

    - by creativz
    Hello, I'm quite impressed with Incskape, it's very powerfull. That's why I wanted to start learning it. But how should I start (to learn it efficiently)? Should I read a book (anybody can recommend me a good one?) or just (inefficiently) do some tutorials on the internet. I really want to learn it to make professional graphics for a webapp or website. So how should I tackle it? Thanks!

  • Flex3 / Air 2: NativeProcess doesn't accepts standard input data (Error #2044 & #3218)

    - by Edward
    Hi: I'm trying to open cmd.exe on a new process and pass some code to programatically eject a device; but when trying to do this all I get is: "Error #2044: Unhandled IOErrorEvent:. text=Error #3218: Error while writing data to NativeProcess.standardInput." Here's my code: private var NP:NativeProcess = new NativeProcess(); private function EjectDevice():void { var RunDLL:File = new File("C:\\Windows\\System32\\cmd.exe"); var NPI:NativeProcessStartupInfo = new NativeProcessStartupInfo(); NPI.executable = RunDLL; NP.start(NPI); NP.addEventListener(Event.STANDARD_OUTPUT_CLOSE, CatchOutput, false, 0, true); NP.standardInput.writeUTFBytes("start C:\\Windows\\System32\\rundll32.exe shell32.dll,Control_RunDLL hotplug.dll"); NP.closeInput(); } I also tried with writeUTF instead of writeUTFBytes, but I still get the error. Does anyone have an idea of what I'm doing wrong?. Thanks for your time :) Edward.

    - by Nico
    Hello there, i have written a simple cgi python script which looks like this #!c:/Python25/python.exe -u import cgi import os def main(): print "Content-type: text/html\n" form = cgi.FieldStorage() print form["firstname"].value os.execvp("D:\\path\\to\\my\\consolapp.exe", [""]) main() As you can se i'd like to start a consoleapp which i have written in .net. But my consoleapp crashs when i call the cgi script. So i did a little debuging and write a text file after some actions i do in my .net program. The result was that my programm crash everytime i'd like to open a access mdb file. It told me that i need the Microsoft Data Access Components (MDAC). But i cant belive this message because my .net consoleapp runs without errors if i start it from my own. So can anybody give me some advise how i can call my .net consol ab through a webscript. I'm happy for every advise So it don't have to be a solution using a cgi script. Regards, Nico

  • Mac OS X, MySQL Preference Pane doesn't work

    - by Steve Kuo
    I downloaded and installed MySQL 5.1.47 for OS X 10.6 using the DMG archive: mysql-5.1.47-osx10.6-x86_64.dmg I also installed MySQL.prefPane and MySQLStartupItem.pkg. MySQL.prefPane is a Preference Pane. The problem is, whenever I attempt to start/stop MySQL from the Preference Pane, System Preferences just hangs. It runs at about 50% CPU forever, eventually I have for force quit System Preferences. The same thing happens if I toggle "Automatically Start MySQL Server on Startup". Basically the MySQL Preference Pane is not functional. Note that I have no problem starting MySQL from the command line: sudo /usr/local/mysql/bin/mysqld_safe I have tried reinstalling MySQL and the Preference Pane. I'm using the standard installation location, nothing out of the ordinary. Every time the MySQL Preference Pane just hangs. I'm doing this on a Macbook Pro (Intel) running OS X 10.6.3. There are no old versions of MySQL on this machine.

  • jQuery datepicker minDate variable

    - by d3020
    I'm usung the jQuery datepicker. In my "EndDate" textbox I'd like to use the date selected from the the "StartDate" textbox + 1. How do I do this? I tried this but didn't work. In my start date code I had... test = $(this).datepicker('getDate'); testm = new Date(test.getTime()); testm.setDate(testm.getDate() + 1); Then in my end date code I had... minDate: testm, but the end date still made all the days for the month available. Thanks. Edit. I'm curious as to why this doesn't work. In my start date datepicker I have this.. onSelect: function (dateText, inst) test = dateText Why can't I come down into my end date datepicker and say, minDate: test?

  • Learn MacRuby or Objective-C?

    - by MaxD
    Well, my fisrt question was a bit too general so i ll try again and hope this one is better. The way i see it is: Ruby-MacRuby or IronRuby or Rails Obj-c-Mac Development So Ruby has clearly more potential in desktop and web platforms and now with MacRuby, OSX native (and commercial) apps are on the way. If i get it wrong please correct me. For me that i will do a fresh start should i go with the modern Ruby or start learning c+obj-c? Will a newcomer benefit much (in learning & coding time, frustration, complexity) by learning/using macruby for osx apps rather objective-c? Or its pretty much the same? I hope some day to hang around here and help others.

  • Best way to unit-test WCF REST/SOAP service while dynamically generating stubs

    - by James Black
    I have a webservice written with WCF 4.0 that exposes REST and SOAP functions, and I want to set up my unit tests so that as I work on my web services I can quickly test by having the test framework start up the service, outside of IIS, and then do the tests. I want it to be dynamically generated as I am not certain what the interface will look like, and it is easier to not worry about having to generate the stubs before I start the tests. But, I couldn't get Groovy to work with my web service, so I am curious if Iron Python or Iron Ruby would work well for this, or is there another .NET language that may work well for this.

  • How to construct a flowchart/storyboard in a Func Spec

    - by PeterQ
    Hey I'm a bit embarrassed to write a post on this topic, but I would appreciate the help. At my school, the CS kids (myself included) have created a nice, little program that is built for incoming Chem/Bio students. It consists of several modules that reviews topics they should have a firm grasp on before they start their classes. It's a nice tool since it cuts down on reviewing the material in class but also allows the students to do a quick diagnostic to fix any problems. Now, I'm in charge of constructing a simple interface that reports on the progress of the group and individual students. The interface is pretty simple. It's just a window that pops up, and it has three tabs: the first tab is a "cumulative" report of all of students. The secnod tab has a drop down box that lists the students and once a student is selected, a report for him/her comes up. And the third tab is simply a description of all of the terms used in the 1st and 2nd tabs. Now, I'm trying to be a good CS student and write a func. spec for my interface. My problem comes with the fact that I'd like to insert a little flowchart using Visio. Problem is, and I'm quite embarrassed to admit this, I don't know how to construct the flowchart/storyboard. For instance, I know I start with a "Start/Click Icon" in a rectangle. Then where do I go? Do I draw three arrrows (one going to each tab) and then describing what goes on? In tab one, the only thing that happens is that the user will select a "sort" method in the drop down box. This will sort the list. The End. Similarly, if the user selects the second tab, then he will go to a drop down box with the student names. Selecting a name will bring up student info. And the third tab is just a list of unfamiliar terms coming from the first or second tab. I wanted to storyboard/flowchart what I'm doing, but I'm unclear how to go about it. Any help would be appreciated! (Just to clarify, I'm not having trouble with using Visio, but I don't know how one goes about construct a storyboard or determining the procedure for constructing one)

  • MediaElement fails after several plays.

    - by basilkot
    Hi! I have a problem with MediaElement control. I've put six MediaElements on my form, then I start them and change played files by timer. After several times, these elements stop playing. Here is the sample XAML: <Grid> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <MediaElement x:Name="element1" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="0" Grid.Row="0" /> <MediaElement x:Name="element2" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="1" Grid.Row="0" /> <MediaElement x:Name="element3" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="2" Grid.Row="0" /> <MediaElement x:Name="element4" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="0" Grid.Row="1" /> <MediaElement x:Name="element5" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="1" Grid.Row="1" /> <MediaElement x:Name="element6" UnloadedBehavior="Close" LoadedBehavior="Manual" Grid.Column="2" Grid.Row="1" /> Here is the sample code: // The code below repeats for each MediaElement List<string> playlist1 = new List<string>() { @"file1.wmv", @"file2.wmv", @"file3.wmv", @"file4.wmv" }; DispatcherTimer timer1 = null; int index1 = 0; ... void Window1_Loaded(object sender, RoutedEventArgs e) { timer1 = new DispatcherTimer(); timer1.Tick += new EventHandler(timer1_Elapsed); timer1.Interval = TimeSpan.FromSeconds(10); element1.Source = new Uri(playlist1[index1]); timer1.Start(); element1.Play(); ... } void timer1_Elapsed(object sender, EventArgs e) { Dispatcher.BeginInvoke(DispatcherPriority.Normal, (System.Threading.ThreadStart)delegate() { element1.Stop(); element1.Close(); timer1.Stop(); index1++; if (index1 >= playlist1.Count) { index1 = 0; } element1.Source = new Uri(playlist1[index1]); timer1.Start(); element1.Play(); }); } ... Does anybody have similar problems?

  • How to use Private Inheritence aka C++ in C# and Why not it is present in C#

    - by Vijay
    I know that private inheritance is supported in C++ and only public inheritance is supported in C#. I also came across an article which says that private inheritance usually defines a HAS-A relationship and kind of an aggregation relationship between the classes. EDIT: C++ code for private inheritance: The "Car has-a Engine" relationship can also be expressed using private inheritance: class Car : private Engine { // Car has-a Engine public: Car() : Engine(8) { } // Initializes this Car with 8 cylinders using Engine::start; // Start this Car by starting its Engine }; Now, Is there a way to create a HAS-A relationship between C# classes which is one of the thing that I would like to know - HOW? Another curious question is why doesn't C# support the private (and also protected) inheritance ? - Is not supporting multiple implementation inheritance a valid reason or any other? Is private (and protected) inheritance planned for future versions of C#? Will supporting the private (and protected) inheritance in C# make it a better and widely used language?

  • Spawn a background process in Ruby

    - by Dave DeLong
    I'm writing a ruby bootstrapping script for a school project, and part of this bootstrapping process is to start a couple of background processes (which are written and function properly). What I'd like to do is something along the lines of: `/path/to/daemon1 &` `/path/to/daemon2 &` `/path/to/daemon3 &` However, that blocks on the first call to execute daemon1. I've seen references to a Process.spawn method, but that seems to be a 1.9+ feature, and I'm limited to Ruby 1.8. I've also tried to execute these daemons from different threads, but I'd like my bootstrap script to be able to exit. So how can I start these background processes so that my bootstrap script doesn't block and can exit (but still have the daemons running in the background)? Thanks!

  • Android Service onBind -> onStart

    - by Gernot
    Hello, I have a comprehension question about Android Services. I have a Service that performs background http operations and a Activity that should display the current state of these http operations. So I implementet the Binder interface and so on. I can call the bindService method and onServiceConnected of my ServiceConnnection is getting called. But as far as I know, onBind doesn't calls onStartCommand() and so onStart() of the Service is never called. So how can I call the onStart() method of the service class and start my operations. Or how is the best way to start my operations in the service, when I also want a binding between the Activity and the Service.

  • using jquery draggable can you create a helper based on the dragged item?

    - by user169867
    I wish to create a custom helper based on the element being dragged. I'm dragging documents and I'd like the document's number to be part of the custom helper. I know how to create a helper during init like this: helper: function() { return $("<div class='fax16'></div>"); } But what I really want to do is maybe in response to the start event get access to the element being dragged and use some of its properties to set the helper. Something like: start: function(event, ui) { var docID = //somehow access the dragged element ui.helper = $("<div class='save16'>" + docID + "</div>"); //Set drag Helper } Can this be done?
