  • Iphone geo location permission check

    - by Johnny Mast
    Dear Developers, Hi i have a quick question about the iphone (iOS) geolocation api's. Currenly i have a map in my application and the operating system will ask the user if it wants to allow the use of geolocations. Now thats all nice but the thing is i want to change my app when geolocations is allowed to a so called "Geo location" mode where new options are available or "standard" mode with less ui elements when permissions are not granted. What can i use to check if permission is granted?. So basicaly is that an api that tells me permission granted yes or no.

  • Question about the benefit of using an ORM

    - by johnny
    I want to use an ORM for learning purposes and am try nhibernate. I am using the tutorial and then I have a real project. I can go the "old way" or use an ORM. I'm not sure I totally understand the benefit. On the one hand I can create my abstractions in code such that I can change my databases and be database independent. On the other it seems that if I actually change the database columns I have to change all my code. Why wouldn't I have my application without the ORM, change my database and change my code, instead of changing my database, orm, and code? Is it that they database structure doesn't change that much? I believe there are real benefits because ORMs are used by so many. I'm just not sure I get it yet. Thank you. EDIT: In the tutorial they have many files that are used to make the ORM work http://www.hibernate.org/362.html In the event of an application change, it seems like a lot of extra work just to say that I have "proper" abstraction layers. Because I'm new at it it doesn't look that easy to maintain and again seems like extra work, not less.

  • WF4RC, How to: Activity to Xaml?

    - by johnny g
    Hello all, I have Googled a bit, and cannot seem to find any examples of Xaml-fying Activities - good, bad, or otherwise! public static string ToXaml (this Activity activity) { // i would use ActivityXamlServices to go from Xaml // to activity, but how to go other way? documentation // is slim, and cannot infer proper usage of // ActivityXamlServices from Xml remarks :S string xaml = string.Empty; return xaml; } Hints, tips, pointers would be welcome :) NOTE: so found this. Will work through and update once working. Anyone wanna beat me to the punch, by all means. Better yet, if you can find a way to be rid of WorkflowDesigner, seems odd it is required.

    - by Naughty.Coder
    Should I learn C#3 or C#4 !? there are alot more books on C#3 than C#4 , would my programming abilities be outdated if I learned C#3 !? And another small question : there are books like : beginning Visual C# 2008 , and Illustrated C# 2008 . The question is : Do they mean the IDE when they mention Visual C# 2008 ?

  • Keypress event on inserted span (jQuery)

    - by Coder
    Hi, I've been researching for a long time, and haven't found a possible solution. The problem I have is that I'm trying to attach an event handler to an span element just inserted. So basically the problem is, when a user performs a particular action that I set (clicking a button by example) I call this function: function AppendSpan() { $('#mydiv').append('<span id="someid" contenteditable="true">Some TExt</span>'); //Then I want to handle the keypress event on the inserted span $('#someid').keypress(function(event){//Do something here}); } The problem is that the keypress event is never triggered on the inserted span, I tried with the click event and it works fine, but not the keypress or keydown,keyup events. I also tried with $('span').live("keypress",function(event){//Do something}); but didn't work. Any suggestions would be appreciated, I need this to work only in FF, so no support for IE required.

  • Is there a Javascript equivalent of .NET HttpWebRequest.ClientCertificates?

    - by Coder 42
    I have this code working in C#: var request = (HttpWebRequest)WebRequest.Create("https://x.com/service"); request.Method = "GET"; // Add X509 certificate var bytes = Convert.FromBase64String(certBase64); var certificate = new X509Certificate2(bytes, password); request.ClientCertificates.Add(certificate, "password")); Is there any way to reproduce this request in Javascript? Third-party libraries would be fine for my purposes.

  • Correct (pretty) window redraw during the creation

    - by Coder
    Does anyone know what is a correct way to redraw window during lengthy initialization operations? Say I have HWND with NULL brush, and it does some not so quick child window initialization (Window initialization is not so quick on Vista and 7, especially on netbooks, even with threaded app). With this config window stays black for half a second on slower laptops. But if I supply window color brush, it seems that there are some sort of child controls or something that draws black squares on top of it, which also seems ugly. Even though the controls are created without WS_VISIBLE initially. Oh, the window has the WS_EX_COMPOSITED style, which should do the double buffering to avoid flicker. But it still behaves ugly. Are there any other tricks I've forgotten, missed?

  • Why my HttpPost can't receive all response data?

    - by Johnny
    I'm on Android 1.5, and my code is like this: HttpPost httpPost = new HttpPost(url); HttpEntity entity = new UrlEncodedFormEntity(params, HTTP.UTF_8); httpPost.setEntity(entity); HttpResponse response = httpClient.execute(httpPost); HttpEntity respEntity = response.getEntity(); String result = EntityUtils.toString(respEntity, DEFAULT_CHARSET); After successfully executed these codes, the result is a stripped string. I've tried using browser to test the url+param, it works fine and got all data. What's wrong with this code? Is there any parameters I need to specified?

  • Parsing XML file using a for loop

    I have been working on this program which inserts an XML file into a MYSQL database. I'm new to the whole .jar idea by inserting packages.

  • Applescript: Tell by Variable dilemma

    - by Johnny Grass
    I would like to do this: tell application "Finder" to set appName to (application file id "com.google.Chrome") as text using terms from application appName tell application appName to get URL of active tab of first window end using terms from This doesn't work because "using terms from" requires an application name as a string constant. If i substitute this line: using terms from application appName with this one using terms from application "Google Chrome" it works. However I don't want to rely on the target machine having the application named "Google Chrome". Using the bundle identifiers seems safer. Is there a better way to do this?

  • Converting OCaml to F#: F# equivelent of Pervasives at_exit

    - by Guy Coder
    I am converting the OCaml Format module to F# and tracked a problem back to a use of the OCaml Pervasives at_exit. val at_exit : (unit -> unit) -> unit Register the given function to be called at program termination time. The functions registered with at_exit will be called when the program executes exit, or terminates, either normally or because of an uncaught exception. The functions are called in "last in, first out" order: the function most recently added with at_exit is called first. In the process of conversion I commented out the line as the compiler did not flag it as being needed and I was not expecting an event in the code. I checked the FSharp.PowerPack.Compatibility.PervasivesModule for at_exit using VS Object Browser and found none. I did find how to run code "at_exit"? and How do I write an exit handler for an F# application? The OCaml line is at_exit print_flush with print_flush signature: val print_flush : (unit -> unit) Also in looking at the use of it during a debug session of the OCaml code, it looks like at_exit is called both at the end of initialization and at the end of each use of a call to the module. Any suggestions, hints on how to do this. This will be my first event in F#. EDIT Here is some of what I have learned about the Format module that should shed some light on the problem. The Format module is a library of functions for basic pretty printer commands of simple OCaml values such as int, bool, string. The format module has commands like print_string, but also some commands to say put the next line in a bounded box, think new set of left and right margins. So one could write: print_string "Hello" or open_box 0; print_string "<<"; open_box 0; print_string "p \/ q ==> r"; close_box(); print_string ">>"; close_box() The commands such as open_box and print_string are handled by a loop that interprets the commands and then decides wither to print on the current line or advance to the next line. The commands are held in a queue and there is a state record to hold mutable values such as left and right margin. The queue and state needs to be primed, which from debugging the test cases against working OCaml code appears to be done at the end of initialization of the module but before the first call is made to any function in the Format module. The queue and state is cleaned up and primed again for the next set of commands by the use of mechanisms for at_exit that recognize that the last matching frame for the initial call to the format modules has been removed thus triggering the call to at_exit which pushes out any remaining command in the queue and re-initializes the queue and state. So the sequencing of the calls to print_flush is critical and appears to be at more than what the OCaml documentation states.

  • SQL: Get count of rows returned from a left join

    - by Rogue Coder
    I have two tables, one called calendars and one called events. There can be multiple calendars, and multiple events in a calendar. I want to select every calendar, also getting the number of events in the calendar. Right now I have : SELECT C.*, COUNT(*) AS events FROM `calendars` AS C LEFT JOIN `events` E ON C.ID=E.calendar GROUP BY C.ID But that doesn't work. Items with no events still return 1. Any ideas?

  • Rails 3, Devise and custom controller action

    - by Johnny Klassy
    routes.rb match 'agencies/stub' => 'agencies#stub', :via => :get resources :agencies Here's the rake routes dump agencies_stub GET /agencies/stub(.:format) {:controller=>"agencies", :action=>"stub"} agencies GET /agencies(.:format) {:action=>"index", :controller=>"agencies"} POST /agencies(.:format) {:action=>"create", :controller=>"agencies"} new_agency GET /agencies/new(.:format) {:action=>"new", :controller=>"agencies"} edit_agency GET /agencies/:id/edit(.:format) {:action=>"edit", :controller=>"agencies"} agency GET /agencies/:id(.:format) {:action=>"show", :controller=>"agencies"} PUT /agencies/:id(.:format) {:action=>"update", :controller=>"agencies"} DELETE /agencies/:id(.:format) {:action=>"destroy", :controller=>"agencies"} Devise is setup to have all agenciesroutes only accessible as admin. The call I'm testing with is http://xyz:12345@localhost:3000/agencies/stub but it doesn't authenticate properly, ie, it doesn't recognize it as admin and throws me back to the Devise login page. The creds are a valid admin account. I'm baffled and have no idea why this is happening. Any insights will be much appreciated.

  • creating BeanInfo objects in NetBeans 6.1 does not work for some objects

    - by Coder
    I have recently learned about BeanInfo classes in Java, and have successfully used them to add icons to my custom GUI components which extend swing components such as JTextField, however i have a more specialized GUI component which extends from another one of my GUI components, which then extends from JTextField. Ie. the class hierarchy is of the form "A - B - JTextField". I can create a bean info object that works for class B, but when i click on the bean info editor option in netbeans to create a bean info object for class A, nothing happens. Ie. there is no error pop-up and a bean info object is not created. There isn't much difference between class A and B. Both A and B have default no argument constructors and they are very similar to each other. The only thing i can really think of is that A uses generics and B does not. I would like to create a beaninfo object for class A so that i can add custom icons for that component. Any help would be appreciated. Thanks.

  • Do you use a grid system when designing a web page?

    - by johnny
    I'm trying to figure out why I would use a grid system. I have read some but I just don't get it. I'm used to just putting stuff in html on a page and beind done with it but I have a new project and would like to use a grid because apparently it is a best practice. I read in one article referenced in another SO question and it said that grid design was in all sorts of development, even application form design. That made me think of things like snap to grid, etc. and I didn't know if the grid in the web design sphere was the same. I was hoping someone could give me a brief but not overly complicated view and not a link to Google which I have used already. Thank you for any help.
