  • Draw a cross at center of a UIImagePickerController.

    - by VansFannel
    Hello. I'm very new on iPhone development. I'm trying to draw a cross over the image obtained from camera. I'm using a custom ViewController that inherits from UIImagePickerController. When I star the application, I see the cross, but a few seconds after the cross disappears. Should I use cameraOverlayView? Thank you

  • Can you bundle a JavaFX jar as an OS X application?

    - by Ianprime0509
    I'm looking for a way to bundle JavaFX applications similarly to the way I can bundle Java applications using Jar Bundler? I really would like to have a custom icon for my program(and the ability to pin it to the Dock). Is there a way to do this now, or do I have to wait for JavaFX to mature in the Java market?

  • Create and display indoor map on Android

    - by Lorenzo Barbagli
    I'm developing an Android application and I would like to display an internal (indoor) map of some buildings, but I don't know where to begin: I want to create a custom kml file (how it's possible to create it? with which tool?) and display it in a fragment. I already have it working with external maps (simple GoogleMap in MapFragment), so it would be super to have the kml file placed 'over' the GoogleMap, like real indoor maps. Thanks

  • Suppressing .net's updatepanel submit event handler

    - by wheresrhys
    I'm performing some custom js validation on my forms, triggered by submitting the form $("form").submit(function (e) { var validates = true; // validation code goes in here if (!validates) { e.preventDefault(); e.stopImmediatePropagation(); return false; } }) None of the lines I've included to stop the submit event prevent the .NET control posting back. Is there some way (using js or setting a property in the updatepanel control) of stopping post back?

  • twisted reactor stops too early

    - by pygabriel
    I'm doing a batch script to connect to a tcp server and then exiting. My problem is that I can't stop the reactor, for example: cmd = raw_input("Command: ") # custom factory, the protocol just send a line reactor.connectTCP(HOST,PORT, CommandClientFactory(cmd) d = defer.Deferred() d.addCallback(lambda x: reactor.stop()) reactor.callWhenRunning(d.callback,None) reactor.run() In this code the reactor stops before that the tcp connection is done and the cmd is passed. How can I stop the reactor after that all the operation are finished?

  • jQuery: on focus, do customized focus on textarea

    - by evilReiko
    My Code: $('#myTextArea').one('focus', function() { $('#myTextArea')[0].selectionStart = 2; $('#myTextArea')[0].selectionEnd = 6; $('#myTextArea')[0].focus(); }); The code works fine, on focus (only once), it selects from index 2 to 6. The problem: since this function is called on focus, it does the custom focus, but then it calls focus AGAIN and I lose focus of the selected text. Any possible solution?

Is this possible to do without graphics?

  • How to recreate the UITabBarItem image filter?

    - by boliva
    Hi, I'm writing a custom UITabBar replacement, and I would like to know how to recreate the filter that the built-in implementation does with the UITabBarItem image - that blue shining on selected tabs and gray gradient on unselected ones. I guess it's a matter of using the source image alpha value as a mask and overlay it with a pre-made blue (or whatever color) shining image and another one grayed out, but I would like to know what is the best approach from a code point of view. Best,

  • How to enforce unique-field validation in MVC

    - by xandy
    I am in the way building some MVC Application and I really love the Data Annotations support in MVC. The build in support is good enough to enforce simple validation checkup.

  • OK to throw an error for a missing required querystring parameter?

    - by Balazs
    Is there anything wrong with having an asp.net page throw a (custom error) if a a required querystring parameter is missing and having global.asax catch it with Application_Error, then transfer the user to an error page? I have several base classes that perform these checks and I am not sure of the best way to communicate the error to a user. So, something like this: int reqParam; if(!isParamSet("myReqParam", out reqParam)) { throw new QuerystringParamMissingException(); } which is then caught by Application_Error in global.asax.

  • How to catch an exception and email information about it in liferay portlet

    - by heikkim
    I have a custom portlet made for liferay and sometimes it throws an exception. Why it throws exceptions is irrelevant. How to catch exceptions thrown by portlet handler methods in order to email information about them? I know I could do try catching on every handler method but it would be a much more elegant and cleaner solution to catch the exception on a higher level and just email some information about the error. I'm using Spring Portlet MVC, so i got all spring-related niceties at hand.

  • TG2.1: Proper location to store a database session instance?

    - by Lee Olayvar
    I am using a custom database (MongoDB) with TG 2.1 and i am wondering where the proper place to store the PyMongo connection/database instances would be? Eg, at the moment they are getting created inside of my inherited instance of AppConfig. Is there a standard location to store this? Would shoving the variables into the project.model.__init__ be the best location, given that under SQLAlchemy, the database seems to commonly be retrieved via: from project.model import DBSession, metadata Anyway, just curious what the best practice is.

  • Combining two UPDATE Commands - Performance ?

    - by Johannes
    If I want to update two rows in a MySQL table, using the following two command: UPDATE table SET Col = Value1 WHERE ID = ID1 UPDATE table SET Col = Value2 WHERE ID = ID2` I usually combine them into one command, so that I do not to have to contact the MySQL server twice from my C client: UPDATE table SET Col = IF( ID = ID1 , Value1 , Value2) WHERE ID=ID1 OR ID=ID2 Is this really a performance gain? Background Information: I am using a custom made fully C written high-performance heavily loaded webserver.

  • jquery show hidden div

    - by Fahad
    Firstly, I'm sort of embarrassed asking about this, so many people have already asked this question but even after having gone through so many posts, I'm unable to achieve what I want. Basically, a div, initially hidden, has to be displayed on a button click. I tried hiding the div using display:none and hide() and then displaying it using show(), toggle(), and css("display","block"). Using all sorts of combinations of the above, I was still unable to get the result. Code: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <link href="css/smoothness/jquery-ui-1.9.2.custom.min.css" rel="stylesheet" type="text/css" /> <script src="jQuery/jquery-1.8.3.min.js" type="text/javascript"></script> <script src="jQuery/jquery-ui-1.9.2.custom.min.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { $('#one').hide(); $('#Button1').click(function () { $('#one').toggle(500); }); }); </script> </head> <body> <form id="form1" runat="server"> <div id="one" style="height: 20px;width:200px; background-color: Red; "> </div> <asp:Button ID="Button1" runat="server" Text="Show" /> </form> </body> </html> On button click, the div is shown for a brief second before it disappears again. The same thing happens if I use show() instead of toggle() in the above code. Again the same thing if I set style="display:none" to the div instead of using hide() and then use show() or toggle(). I also tried using $('#one').css("display","block"); but again, the same result. Can anyone please tell me where I'm going wrong. Just started learning jQuery and it is really frustrating when something apparently so simple will not work. Thanks in advance. :)

  • Online graphing and data visualization frameworks

    - by Marques
    I have been looking around at web applications and websites with rich graphs, charts, and data visualization and for the most part have been able to determine which frameworks or tools websites are using. However I was looking over 'resumup.com' and couldn't determine what they are using. Does anyone know off hand or can you tell? It doesn't seem like any javascript framework i've seen unless its custom...is it some sort of flash or flex framework? Any help would be greatly appreciated. Thanks, Marques
