• IconDownloader, problem with lazy downloading

  - by Junior B.

  My problem is simple to be described but it seems to be hard to solve. The problem is loading icons, with a custom class like IconDownloader.m provided by an official example from Apple, avoiding crashes if I release the view. I've added the IconDownloader class to my app, but it's clear that this approach is good only if the tableview is the root. The big problem is when the view is not the root one. F.e: if I start to scroll my second view (the app now load the icons) and, without leaving it the time to finish the download, I go back to root, the app crash because the view that have to be updated with new icons doesn't exist anymore. One possible solution could be implement an OperationQueue in the view, but with this approach I've to stop the queue when I change the view and restart it when I come back and the idea to have N queues don't make me enthusiastic. Anyone found a good solution for this problem?

• Custom prerequsites to visual studio setup project

  - by Sandy

  I have a Visual Studio Setup project and have followed the steps mentioned in this link to load the Shared Add-in Support Update for the Microsoft .NET Framework 2.0 (KB908002) to the prerequisites list. The entry appears but there is this following warning shown No 'HomeSite' attribute has been provided for 'Shared Add-in Support Update for Microsoft .NET Framework 2.0 (KB908002)', so the package will be published to the same location as the bootstrapper. I use the Download component from the component vendor's website option. How do I set a homesite for this update so that the update is directly downloaded and installed. I do not want to distribute the update along with my setup. Thanks

• Dynamically loading JavaScript synchronously

  - by spoon16

  I'm using the module pattern, one of the things I want to do is dynamically include an external JavaScript file, execute the file, and then use the functions/variables in the file in the return { } of my module. I can't figure out how to do this easily. Are there any standard ways of performing a pseudo synchronous external script load? function myModule() { var tag = document.createElement("script"); tag.type = "text/javascript"; tag.src = "http://some/script.js"; document.getElementsByTagName('head')[0].appendChild(tag); //something should go here to ensure file is loaded before return is executed return { external: externalVariable } }

• Android: Using GEO uri

  - by Sebastian

  Hi, I have read the doc and some tutorials to get a .kml file working launching the google maps activity. When I hosted the file in a server, this works perfectly: Intent myIntent = new Intent( android.content.Intent.ACTION_VIEW, Uri.parse("geo:0,0?q=http://somedomain.com/file.kml") ); Now, reading this link on how to use intents for gmaps with the developing stage of GEO uri I can't manage how to load a kml file from within the device, I have tried with "q=file:///path-to-file.kml" and with an absolute path too. Has anyone done this yet? PS: in IRC channel recommend me to use apps based on openstreetmaps, but the docs is much more poor than the gmaps doc althought they are OS.

• jquery/javascript: accessing contents of an iframe

  - by rz

  I would like to manipulate the html inside an iframe using jquery. I thought I'd be able to do this by setting the context of the jQuery function to be the document of the iframe, something like: $(function(){//document ready $('some selector', frames['nameOfMyIframe'].document).doStuff() }); However this doesn't seem to work. A bit of inspection shows me that the variables in frames['nameOfMyIframe'] are undefined unless I wait a while for the iframe to load. However, when the iframe loads the variables are unaccessible (I get permission denied type errors). Does anyone know of way to work around this?

• deploying flex on tomcat

  - by ron

  Hello, I am using Flash builder 4 (SDK3.5) to create my flex program. I want to deploy this program and load it to a tomcat server. I configure my "flex server" root folder and other parameters in the project properties. The problem is, that i don't know how to make it generic. e.g. my friend's tomcat is installed in other directory on the computer. I know that in eclipse i can run the server and tomcat from the IDE. I can't see how i do it in Flash builder plugin for eclipse 4. There is a server configuration, but there isn't adapter for tomcat. Any ideas? thanks.

• google maps plot route between two points

  - by amarsh-anand

  I have written this innocent javascript code, which lets the user create two markers and plot the route between them. It doesnt work, instead, it gives a weird error: Uncaught TypeError: Cannot read property 'ya' of undefined Can someone suggest me whats wrong here: // called upon a click GEvent.addListener(map, "click", function(overlay,point) { if (isCreateHeadPoint) { // add the head marker headMarker = new GMarker(point,{icon:redIcon,title:'Head'}); map.addOverlay(headMarker); isCreateHeadPoint = false; } else { // add the tail marker tailMarker = new GMarker(point,{icon:greenIcon,title:'Tail'}); map.addOverlay(tailMarker); isCreateHeadPoint = true; // create a path from head to tail direction.load("from:" + headMarker.getPoint().lat()+ ", " + headMarker.getPoint().lng()+ " to:" + tailMarker.getPoint().lat() + "," + tailMarker.getPoint().lng(), { getPolyline: true, getSteps: true }); // display the path map.addOverlay(direction.getPolyline()); } });

• seo custom domains

  - by BamBam

  I'm trying to do the following: I have website like apartments.com. sometimes, I want to expand to different cities, so for SEO purposes, I might create a separate domain like bostonapartments.com or newyorkapartments.com for only boston and new york apartments. bostonapartments.com and the main domain apartments.com are all hosted on 1 server. what I did was I used Virtual Host apache config to direct bostonapartments.com to a directory on that server, and then used an iframe to load content for bostonapartments.com from apartments.com. So all the content will be hosted on apartments.com, but bostonapartments.com will get the content from apartments.com. how can I accomplish this effectively in a scalable way using php, apache, mysql? btw, I do not own apartments.com, I'm just using that as an example.

• Pass logger instance to class

  - by mridang

  Hi Guys, I'm using a open-source Python library in my project. This library logs a lot of information using the logging class. ...but I can't see the output or log it to file. I know that i would have to create a logger instance and add a file-handler or a console-handler to it but how can i pass this logger instance to the class? Here's the init snippet of the class that I'm going to be using. class Periscope: ''' Main Periscope class''' def __init__(self): self.config = ConfigParser.SafeConfigParser({"lang": "en"}) if is_local: self.config_file = os.path.join(bd.xdg_config_home, "periscope", "config") if not os.path.exists(self.config_file): folder = os.path.dirname(self.config_file) if not os.path.exists(folder): logging.info("Creating folder %s" %folder) os.mkdir(folder) logging.info("Creating config file") configfile = open(self.config_file, "w") self.config.write(configfile) configfile.close() else: #Load it self.config.read(self.config_file) self.pluginNames = self.listExistingPlugins() self._preferedLanguages = None Any help?

• Debugging ASP.NET Session State server issues

  - by Cleggy

  We have an application that runs over load balanced server instances, and therefore is configured to use the ASP.NET session state service, which is running on one of our DB servers. While both instances of our app can successfully connect to the state server, changes in session state data are not being reflected across both of them. FI, If I call Session.Add('SomeKey', SomeData) on Server A, this is not being reflected if I then try to access Session['SomeKey'] on Server B. Session.SessionID returns the same value on both servers, and I have checked that they are both using the same validationkey and decryptionkey values configured in the machinekey section of machine.config. I even tried specifying these values in the apps web.config. What other things should I be looking out for which may be causing these symptoms, and what steps can people recommend to help debug this issue?

• Managing the localization of Java properties files

  - by andri

  I have a Web application written in Java that is targeting several countries, all of which speak different languages (and more often than not, several languages -- that's Europe for you). We have a bunch of .properties files that hold the localized strings, and our current procedure is to e-mail the language-specific files to our partners for updating before doing major updates. However, this process is rather error-prone, as sometimes people forget to translate new strings and sometimes new strings don't get added to every language file, thus small mistakes get through very easily. Does anyone know of any existing software that could help us clear this mess? At a bare minimum, I'm thinking of something that would allow you to load a master file (for example, in English), a localized file and then would highlight the keys that were added to or removed from the master file.

• Scope of variables inside of javascript

  - by wcpro

  I have the following code sample that im trying to wrap my head around $(document).ready(function () { test("load json", function () { length = 0; // length = 0 $.getJSON("plugins/form.json", function (data) { length = data.fields.length; // length = 4 }); ok(length == 4, "length = " + length.toString()); // length = 0? wtf? }); }); the 'length' variable does not persist when the $.getJSON runs. I cant figure out if its because its asynchronous or because the variable is out of scope.

• WPF MenuItem Content "Name"...

  - by Kyle

  Hi, I have a LOT of MenuItem(s), and I want to be able to change their "Content" so that it displays in the program. When I load up the program, their "Content Name" is set in a Setter I created.. but the only problem is that I have almost a hundred MenuItem objects, and I need their display names in the program to be different (not the setter's default). I could just create over 100 different "Setter"'s and change one line in them.. but that is very time consuming. Is there a simpler approach? I want to be able to do this in the XAML where I am declaring them. Is there a way to do this? I've been searching and trying different attempts, but nothing so far.. perhaps someone knows? Thanks

• Where is the best place to run initialization code for a UITabBarController?

  - by bobobobo

  I have a UITabBarController in my application. I have to perform some customization to the NIB file using code the first time a view embedded in that UITabBarController gets loaded. When applicationDidFinishLaunching occurs, the UITabBarController's views apparently are not loaded -- if I try to modify the view controllers inside a tab bar that the tab bar is to load in applicationDidFinishLaunching, then those changes are ignored. I'm assuming this is because the tab bar didn't finish loading yet. So, I need a good place to put code that will run immediately after a tabbar is fully ready -- i.e. after it has loaded all the views from their respective nib files. I'm finding the only place I can do this is to track the first time viewDidAppear on each individual view controller. Note I can't use viewWillAppear because I need the value of tabBarController.selectedIndex to be accurate, and it is only actually updated after viewDidAppear gets fired, not when viewWillAppear gets fired.

• How do I unhide a CFDIV that has dynamic content with AJAX binding itself?

  - by Eric Belair

  I have the following CFSELECT tags that are used to populate a text input: <cfselect id="this" name="this" bind="cfc:Data.getThis()" bindonload="true" /> <cfselect id="that" name="that" bind="cfc:Data.getThat({p1})" /> <cfselect id="theOther" name="theOther" bind="cfc:Data.getTheOther({p1}, {p2})" /> The text input is the only value that needs to be submitted in a form: <cfform name="addItem" method="post" action="somepage.cfm"> <cfinput type="text" id="item" name="item" bind="cfc:Data.getResult({this}, {that}, {theOther})" /><br /> <cfinput type="submit" name="addButton" value="Add Item" /> </cfform> I want the form and it's contents to be visible only when all three selections have been made, and there is a value for the text input. What is the best way to do this? I'm assuming some use of CFDIV is the best way, but I'm not sure how to load the dynamic content (the CFINPUTs) this way.

• Display Ajax Loader while page rendering

  - by Dean

  This is probably a simple question but how can I best use an AJAX loader in ASP.NET to provide a loading dialog whilst the page is being built? I currently have an UpdatePanel with an associated UpdateProgressPanel which contains the loading message and gif in a ProgressTemplate. Currently I have a page that onLoad() goes and gets the business entities and then displays them. While it is doing this I would like to display an AJAX loader. Would it be better to have nothing in the page load and have a hidden button that is triggered onLoadComplete or unLoad() which would then wait for the button click method to complete displaying the UpdateProgressPanel?

• How to extract a Sub-Matrix from a Matrix ?

  - by ZaZu

  Hello, I have a matrix in a txt file and I want to load the matrix based on my input of number of rows and columns For example, I have a 5 by 5 matrix in the file. I want to extract a 3 by 3 matrix, how can I do that ? I created a nested loop using : FILE *sample sample=fopen("randomfile.txt","r"); for(i=0;i<rows;i++){ for(j=0;j<cols;j++){ fscanf(sample,"%f",&matrix[i][j]); } fscanf(sample,"\n",&matrix[i][j]); } fclose(sample); Sadly the code does not work .. If I have this matrix : 5.00 4.00 5.00 6.00 5.00 4.00 3.00 25.00 5.00 3.00 4.00 23.00 5.00 2.00 352.00 6.00 And inputting 3 for rows and 3 for columns, I get : 5.00 4.00 5.00 6.00 5.00 4.00 3.00 25.00 5.00 Which is obviously wrong , its reading line by line rather than skipping the unmentioned column ... What am I doing wrong ? Thanks !

• Communicating from website to desktop application (not vice-versa)

  - by chakrit

  I am designing an application such that it will have to react to certain actions required by the website, mostly the same way Last.FM client does (if you have used one) The way Last.FM client works is that, it will register a custom protocol in Windows (lastfm://) and on their website, they use that protocol to trigger certain action on the player, e.g.: lastfm://artist//similarartists will actually direct any Last.FM client running to load up similar artists. I would like to do the same thing for my application. Is this a good idea? Is there any good alternatives to send a message from a website to a desktop client in this manner?
