• Develop iPhone application remotely?

  - by ANE

  4 java developers are new to iPod Touch/iPhone app development. They have an idea for an app. They have never used Xcode or Macs before. Instead of spending money for a new iMac or Mac Mini for each of them, my boss would like to sell them a $999 Apple server, hosted at a facility connected a single T1 line, and have all 4 people work remotely in Xcode. Is this feasible? Is anyone doing anything like this? Specifically, is 1 T1 enough for realistic remote app development? Would they have to work in black & white via Logmein or Gotomeeting to get decent speed? Can four people work remotely together on an Xcode project at the same time? Do they absolutely need their own Macs to connect their iPod Touches or iPhones physically to, or can they connect to their existing PCs with iTunes and install their in-development apps that way?

• Painting on GtkScrolledWindow or GtkEventBox

  - by ptomato

  Using GTK, I'm trying to overlay a "More" prompt (but it could just as well be any drawing object) in the corner of a GtkTextView contained within a GtkScrolledWindow. I draw the prompt in the handler for the expose signal of the text view. It works, but when I scroll the window I get artifacts: the prompt is moved along with the contents of the text view and not erased. In order to get rid of the artifacts I trigger a redraw after each scroll. This mostly works, but you can still see the prompt jumping up and down when you scroll quickly. Is there any way to prevent this? It would be nice if the prompt just "floated" on top of the text view. I tried enclosing the scrolled window in a GtkEventBox and painting the prompt on top of that, but that didn't work either; the scrollbars and text view always paint over the prompt, even when you set the event box's window to go in front of its children's windows. UPDATE If I connect the GtkEventBox's expose callback with g_signal_connect_after(), then it is called after the expose callbacks of the GtkScrolledWindow and GtkTextView. The text view still draws over the event box though. I think this is because the scrolling happens asynchronously. Anybody got any idea how I can prevent my drawing from being overwritten?

• Java jList add item based on combobox selection

  - by Stephan Badert

  I have a csv file that is being loaded in my programme. It contains citys and areas and some other stuff (not important here). Once the csv is selected I load the data into several comboboxes. 1 Thing is not working, I have a combobox containing all the citys and now I need to list all the areas for that country based on selection from the combobox. Here is the event: private void cboProvinciesItemStateChanged(java.awt.event.ItemEvent evt) { //System.out.println(Arrays.asList(gemeentesPerProvincie(gemeentes))); invullenListProvincie(gemeentes); } Here is the method: private void invullenListProvincie(ArrayList<Gemeentes> gemeentes) { Gemeentes gf = (Gemeentes) cboProvincies.getSelectedItem(); DefaultListModel model = new DefaultListModel(); JList list = new JList(model); for (Gemeentes gemeente : gemeentesPerProvincie(gemeentes)) { model.addElement(gemeente); } lstGemeentes.setModel(model); } and this is the method to filter all the areas that equal the selection from the combobox: private ArrayList<Gemeentes> gemeentesPerProvincie(ArrayList<Gemeentes> gemeentes) { String GemPerProv = (String) cboProvincies.getSelectedItem(); ArrayList<Gemeentes> selectie = new ArrayList<Gemeentes>(); for (Gemeentes gemeente : gemeentes) { if (gemeente.getsProvincie().equals(GemPerProv)) { selectie.add(gemeente); } } return selectie; } I am convinced the error is the way I am trying to add items to the jList gemeentesPerProvincie(), I have tried so many things already. I really hope someone can see what i am clearly missing...

• Delete/move a UITableView row that's attached to a web service.

  - by Kevin L.

  Deleting or moving rows for a UITableView that is backed with local data (e.g., NSArray) is easy and instantaneous: Remove the value from the array. Call deleteRowsAtIndexPaths:withRowAnimation:. Profit! But my table view communicates with a web service, which means once the "Delete" button on that row gets tapped, I have to forward a request on to the server (via ASIHTTPRequest, of course), get the response, and then tell the table view to run its little delete-row animation, all with a few seconds of latency in between. From a high-level, what's the best way to do that? Throw some callback selector into ASIHTTPRequest's userInfo dictionary? KVO? Bonus points for some nice UI touch, like some kind of spinner on the soon-to-be-deleted cell.

• Add Hover display for table cell

  - by Jake

  I have a table, but it is not in a list format, meaning not a column/row format. I look for specific cells to add a hover event that displays a description of the cell. $("#TableID td").hover(function(){ //ifCellThatIWant $(this).append("<span>Message that was brought in</span>"); }, function(){ $(this).children().remove(); }); The problem is right now is that the hover displays a span(with info. inside) that I used jquery to append the span to the cell when mouseover, which expands the cell, which is an effect that I don't like or want. I'm Trying to have an out of the table look,but still be by the cell that triggered the event; because if the span has a lot of info. in it, expanding the cell dynamically will start to look pretty nasty. Also will help if I had some type of css direction on how will I make the display for the mouseover "description" span look nice. My mind thought is that a way to accomplish what I want is giver the appended span the position of my mouse cursor when hover, but not sure if its the right approach or what the syntax would look like.

• Objective C: Using UIImage for Stroking

  - by SeongHo

  I am trying to apply a texture for my brush but i'm really having a hard time figuring how it is done. Here's the image of my output. I used an UIImage that just follows the touch on the screen but when i swipe it faster the result is on the right side "W", and on the left side that's the result when i swipe it slow. i tried using the CGContextMoveToPoint and CGContextAddLineToPoint i don't know how apply the texture. Is it possible to use UIImage for the stroke texture? Here's my code UIImage * brushImageTexture = [UIImage imageNamed:@"brushImage.png"]; [brushImagetexture drawAtPoint:CGPointMake(touchCurrentPosition.x, touchVurrentPosition.y) blendMode:blendMode alpha:1.0f];

• help to reiterate through my jquery snippet

  - by s2xi

  Code in question: $("#alpha").click(function(event) { event.preventDefault(); $("#show").slideToggle(); }); I have a list of files and its being outputted with PHP in alphabetical. I use this method in PHP: foreach(range('A','Z') as $i) { if (array_key_exists ("$i", $alpha)) { echo '<div id="alpha"><a href="#" name="'.$i.'"><h2>'.$i.'</h2></a></div><div id="show">'; foreach ($$i as $key=>$value) echo '<p>'.$value.' '.$key.'</p>'; } echo '</div>'; } What I want to do is when the user clicks on the #alpha to toggle the div #show that has the names that belong to a letter up. I can do this with the first listing, but every listing after that isn't affected. how can i tell jquery that foreach letter apply the js code so it can toggle up/down the #show. I don't want to this 26 times (one time for each letter in the alphabet), I tried to use class instead of id but that causes all the #show to toggleup heh.

• Sharepoint 2010 start workflow programmatically error

  - by user522429

  I have a workflow associated with a content type. I try to kick it off from code from within the event receiver on the same content type, so when an item is updated, if there is a certain condition (status = ready for review) I start it. //This line does find the workflow association var assoc = properties.Web.ContentTypes["Experiment Document Set"].WorkflowAssociations.GetAssociationByName("Experiment Review Workflow", ultureInfo.CurrentUICulture); //I had tried to use this line from something I found online, but it would return null //var assoc = properties.Web.WorkflowAssociations.GetAssociationByName("Experiment Review Workflow", CultureInfo.CurrentUICulture); var result = properties.Web.Site.WorkflowManager.StartWorkflow(properties.ListItem, assoc, string.Empty, SPWorkflowRunOptions.Synchronous); //The line above gives me this error: System.ArgumentException: Workflow failed to start because the workflow is associated with a content type that does not exist in a list. Before re-starting the workflow, the content type must be added to the list. To check this, I was looking at the content type of the list item being updated and it is correct properties.ListItem.ContentType.Name "Experiment Document Set" So basically I have a workfow associated with the content type "Experiment Document Set". When I try to start a workflow from an event receiver in "Experiment Document Set", I get an error saying the content type "Experiment Document Set" does not exist in the list which doesn't make sense.

• simplemodal click events stopped working in IE7

  - by prettynerd

  Here's my code: $('#alertInfo').modal({ close :false, overlayId :'confirmModalOverlay', containerId :'confirmModalContainer', onShow : function(dialog) { dialog.data.find('.message').append(message); dialog.data.find('.yes').click(function(){ if ($.isFunction(callback)) callback.apply(); $.modal.close(); }); dialog.data.find('.close').click(function(){ $.modal.close(); }); } }); Basically, this is a dialogue box which I call to show a warning message that has a "X" button (with class 'close') and an "OK" button (with class 'yes'). The problem occurs in IE7. When I call this dialogue box and use my "X" button to close it everytime, my "X" button does not work anymore on the third time I call it (YES ON THE THIRD TIME!). However, if I use my "OK" button to close the dialogue box, it works fine no matter how many times I call it. I thought I found a workaround by unbinding and binding my click event of the '.close' class, as below: dialog.data.find('.close').unbind('click'); dialog.data.find('.close').bind('click',function(){$.modal.close();}); and it worked!!! unfortunately, however, the problem now occurs in my "OK" button. so, i did the same unbinding and binding the click event of the '.yes' class, as below: dialog.data.find('.yes').unbind('click'); dialog.data.find('.yes').bind('click', function() { if ($.isFunction(callback)) callback.apply(); $.modal.close(); }); BUT NOPE, IT DOES NOT WORK.. please help me.. @ericmmartin, i hope you're online now.. huhu..

• Concurrent connections in C# socket

  - by Chu Mai

  There are three apps run at the same time, 2 clients and 1 server. The whole system should function as following: The client sends an serialized object to server then server receives that object as a stream, finally the another client get that stream from server and deserialize it. This is the sender: TcpClient tcpClient = new TcpClient(); tcpClient.Connect("127.0.0.1", 8888); Stream stream = tcpClient.GetStream(); BinaryFormatter binaryFormatter = new BinaryFormatter(); binaryFormatter.Serialize(stream, event); // Event is the sending object tcpClient.Close(); Server code: TcpListener listener = new TcpListener(IPAddress.Parse("127.0.0.1"), 8888); listener.Start(); Console.WriteLine("Server is running at localhost port 8888 "); while (true) { Socket socket = listener.AcceptSocket(); try { Stream stream = new NetworkStream(socket); // Typically there should be something to write the stream // But I don't knwo exactly what should the stream write } catch (Exception e) { Console.WriteLine("Exception: " + e.Message); Console.WriteLine("Disconnected: {0}", socket.RemoteEndPoint); } } The receiver: TcpClient client = new TcpClient(); // Connect the client to the localhost with port 8888 client.Connect("127.0.0.1", 8888); Stream stream = client.GetStream(); Console.WriteLine(stream); when I run only the sender and server, and check the server, server receives correctly the data. The problem is when I run the receiver, everything is just disconnected. So where is my problem ? Could anyone point me out ? Thanks

• Jquery - removing an image before the client browser attempts to download it

  - by ajbrun

  Hi there, I wonder if anyone could help me with a problem I've been having. I have a number of large images available, but due to space limitations, I can't create multiple copies of these at various sizes. I have used PHP GD functions to resize the images to the sizes I need and output them to the browser. This works, but obviously takes some processing time, which therefore impacts pages load times. I'm fine with this, but I only want to show the image once it's fully loaded, and have a loading gif in its place until that time. I'm using jquery to do this. The problem I'm having is making the page functional whether the client has javascript enabled or not. If JS is not enabled, I want standard img tags to be outputted, otherwise the images are removed and replaced with a loading gif until they have been fully loaded. The link below shows a simple non-javascript unfriendly example of a what I want to do (try turning JS off): http://jqueryfordesigners.com/demo/image-load-demo.php I've been testing the basics using the code below. The attr() function will be replaced with something like remove(). This is just a test to make something happen to the image before the browser tries to load it. $(document).ready(function() { $( "#Thumbnails .thumbnail img" ).attr('src', '#'); }); In IE, this works correctly - the image source is replaced with "#" BEFORE the client browser gets a chance to start downloading the image. In firefox however, it downloads the image, and THEN changes the source. It seems to me that firefox is loading the jquery onready event later than it should. As far as I know, this should be executed before the standard onload event and before anything has started loading. If it helps, I'm testing it with a good number of images on screen (81). Am I doing something wrong?

• Facebook call back function with timeout

  - by Dirty Bird Design

  So I've been getting my ass kicked pretty good with Facebook's moving target of an API. I need to display some hidden content after a person clicks 'like' on a landing page. I can somewhat get this to work, when the user clicks 'like' the normal fb dialogue appears and then goes away immediately and content is displayed. I have 'achieved' this with the following js. <script> FB.Event.subscribe('edge.create', function(href, widget) { document.getElementById('goodies').style.display = "block"; document.getElementById('fb-content').style.display= "block"; document.getElementById('copy').style.display = "none"; }); </script> I cannot find any documentation about a callback event after someone hits "post to facebook" or after the dialogue closes, only afte they hit like. How would I incorporate a setTimeout function into this to give people some time to fill out the fb dialogue? thanks. If anyone has a better way to do this I'm all ears. This is for a business page and I cannot seem to add an app to get an app ID anymore so the API is pretty useless to me at this point. Also, if the url to be liked is a fb page, the callbacks don't seem to fire. Other code used: <html xmlns:fb="http://ogp.me/ns/fb#"> <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk')); </script> <fb:like href="onlynonfburl.com" send="false" layout="button_count" width="450" show_faces="false" font="arial"></fb:like>

• ASP.NET UserControl Caching

  - by Adam

  Hi, This thing is driving me nuts. I have a UserControl that is called WebUserControl. I need to cache this control, so I put the following in the WebUserControl.ascx: <%@ OutputCache Duration="240" VaryByParam="FeedName" %> Then I have the Default.aspx file in which I have: <div class="divInnerLeft" id="L1" runat="server"> <uc1:WebUserControl FeedId="a1" ID="a1" runat="server" FeedName=""/> </div> <div class="divInnerMiddle" id="M1" runat="server"> <uc1:WebUserControl FeedId="a3" ID="a3" runat="server" FeedName=""/> </div> In the Page_Load event I set the FeedName property - according to the user preferences. The problem is that after initially loading the page, the controls are generated OK. But then, in the Page_Load event they are not available again. So the a1 and a3 are null and I cannot set the FeedName for different user. How to solve this? Thanks!

• Flex 4: Scale to a point (zoom into an image where the mouse was clicked)

  - by Jason W

  I've been trying to get this working and I can't seem to figure it out. There is an Image control that when I click on it I need to zoom in (using the center/transform point where the mouse is clicked). I have the zoom transition working great, but when I set transformX & tranformY (with autoCenterTransform false) it doesn't zoom into that point. Here is my code that only zooms in (not to a specific point) <fx:Script> <![CDATA[ protected function imgLogo_clickHandler(event:MouseEvent):void { transformer.play(); } ]]> </fx:Script> <fx:Declarations> <s:Parallel id="transformer" target="{imgLogo}"> <s:Scale scaleXBy="0.5" scaleYBy="0.5" /> </s:Parallel> </fx:Declarations> <mx:Image id="imgLogo" width="250" x="100" y="100" maintainAspectRatio="true" source="@Embed('src/logo.png')" click="imgLogo_clickHandler(event)" /> Any help is greatly appreciated. Thanks

• how to change uibutton title at runtime in objective c?

  - by Sarah

  Hello, I know this question is asked many a times,and i am also implementing the same funda for chanding the title of the uibutton i guess. Let me clarify my problem first.

I am not getting where i am making mistake.I have allocated memory to the btnType at viewdidLoad.

Also i would like to mention that i have made connection with IB with event TouchUpInside for pressAddType. Any guesses? I will be grateful if you could help me. Thanks.

• Why am I needing to click twice on a WPF listbox item in order to fire a command?

  - by Donal

  Hi, I'm trying to make a standard WPF listbox be dynamically filled, and for each item in the list box to launch a command when clicked. Currently I have a working listbox, which can be filled and each item will fire the correct command, but in order to fire the command I have to click the list item twice. i.e, Click once to select the item, then click on the actual text to fire the command. As the list is dynamically created, I had to create a data template for the list items: <ListBox.ItemTemplate> <DataTemplate> <TextBlock Margin="4,2,4,2"> <Hyperlink TextDecorations="None" Command="MyCommands:CommandsRegistry.OpenPanel"> <TextBlock Text="{Binding}" Margin="4,2,4,2"/> </Hyperlink> </TextBlock> </DataTemplate> </ListBox.ItemTemplate> Basically, how do I remove the need to click twice? I have tried to use event triggers to fire the click event on the hyperlink element when the list box item is selected, but I can't get it to work. Or, is there a better approach to dynamically fill a listbox and attach commands to each list item? Thanks

• Safe ASCII char to replace whitespace before storing

  - by AngryWhenHungry

  My code passes a big bunch of text data to a legacy lib, which is responsible for storing it. However, it tends to remove trailing whitespace. This is a problem when I read the data back. Since I cannot change the legacy code, I thought about replacing the all spaces with some uncommon ASCII character. When I read back the text, I can replace them back. Is this a bad idea, considering that I cannot touch the legacy storage code? Which character can I use as a substitute? I was considering some char upwards of 180. There will only be spaces - no tabs or newlines - in the data. The data is alphanumeric, with special characters.

• actionscript 3 website load movieclips (frames) from library

  - by steve

  Here is my current code that doesn't function: import flash.display.*; import fl.transitions.*; import flash.events.MouseEvent; stop(); var contentBox:MovieClip = new MovieClip(); contentBox.width = 400; contentBox.height = 500; contentBox.x = 400; contentBox.y = 0; var closeBtn:close_btn = new close_btn(); closeBtn.x = 850; closeBtn.y = 15; var bagLink:MovieClip = new bag_link_mc(); bagLink.x = 900; bagLink.y = 0; menu_bag_button.addEventListener(MouseEvent.CLICK, bagClick); function bagClick(event:MouseEvent):void{ if(MovieClip(root).currentFrame == 835) { } else { MovieClip(root).addChild (contentBox); MovieClip(root).contentBox.addChild (bagLink); MovieClip(root).contentBox.addChild (closeBtn); MovieClip(root).gotoAndPlay(806); } } closeBtn.addEventListener(MouseEvent.CLICK, closeBag); function closeBag (event:MouseEvent):void{ MovieClip(root).removeChild(contentBox); MovieClip(root).gotoAndPlay(850); } I don't know ActionScript at all, so this may be the complete wrong way of approaching it. The setup is as follows: site loads, there's a big menu in the center (frame 805). When you click on a menu item from there, the whole menu moves to the side, and the right side I want a "contentBox" movieclip, filled with "bagLink" (which is site content) and to have a close button (closeBtn.) It also needs to know that if you click the same link again on the left side that it doesn't reanimate, it just stays (which I achieved with the "if" statement.) Finally, if someone clicks another link, it needs to clear "contentBox" and refill it with whatever movieClip that was clicked. I know this is a lot to ask, but I'm in dire need of help as this is due on Wednesday...

• When iterating over values, why does typeof(value) return "string" when value is a number? Javascrip

  - by Mark

  I'm using Google Chrome for this test: Contrary to intuition, the first loop alerts "string" 3 times, while the second loop alerts "number" 3 times. numarray = [1, 2, 3]; //for-each loop for(num in numarray) alert(typeof(num)); //standard loop for(i=0; i<numarray.length; i++) alert(typeof(numarray[i])); I was expecting both loops to alert "number" 3 times. How is the first loop implemented in Javascript? In other words, if the for-each is syntactic sugar, what is its equivalent using a standard loop? Also, is there some way to iterate over an object's namespace using a standard loop? I'm looking to touch every one of some object's methods and attributes using a loop of the second kind. I'm new to Javascript and any help is highly appreciated, thanks.

• Is it possible to pass Calendar new date in the bean without listener?

  - by isabsent

  I am trying to pass new date from PrimeFaces p:calendar (placed in p:dataTable column) to the backing bean: <p:column > <p:calendar value="#{bean.date}">` <p:ajax /> </p:calendar> </p:column> It does not update bean.date. Variants with <p:ajax update="@this" event="change"/> <p:ajax update="@this" event="select"/> do not update bean.date too. The only way I have found is using of listener. However, I suppose, there should be a way without listener implementation like for simple facelets: <p:column> <h:inputText value="#{bean.note}" > <f:ajax/> </h:inputText> </p:column> that works fine for me. Does anybody know how to get it working!?

• Quick question regarding MVC framework for a java game

  - by Jason

  I have a question regarding the use of the MVC framework for a blackjack game im writing in java. As I understand, my model would be a class that stores the state of the game, and more specifically, each players hand. Within the model class, I would have an array of listeners, which would be notified each time the game state changes (ie a player has drawn a new card). These listeners would be my viewer, which is the class that handles the display of the game. This class would implement the ActionListener interface, and each time the model changes, it would call/"notify" my viewer's actionPerformed method. My question is as follows: I intend to have two JPanels, each devoted to displaying the respective player's hand. As a player draws a new card, a new ImageIcon would be added to the panel. My question is how would the viewer class know what card has been added to the player's hand? I suppose I could store the player's hand before a notify event, and then upon the notification event, compare the new state with the old, to find out what has changed. I'm a complete novice here, so I could be completely wrong, but it seems a bit tedious to do this. Is there a more efficient/common way of detecting what has changed in the model between the before and after state? Another solution would be to redraw the entire panel each time the notification occurs? Would this be a better idea?
