  • pass string or data of local file between viewcontrollers

    - by Jonathan
    In my last question i asked how to best send a string from one view controller to another, both which were on a navigation stack: http://stackoverflow.com/questions/2898860/pass-string-from-tableviewcontroller-to-viewcontroller-in-navigation-stack However I just realised I can either pass the path to the file in the app's document's folder as the first (the table view) has already accessed the data in the file should I pass viewcontroller the data to the pushed VC?

  • ASP.Net MVC TimeSpan as action parameter?

    - by HeavyWave
    I am trying to use TimeSpan as a parameter type for an action in a controller, but the value is always now, so I presume it is not parsed correctly by MVC. The value that gets sent to it is "7:00 PM". Is it possible to make MVC support such format? I am using MVC 2.

  • Static method,new thread performance question

    - by ylazez
    Hey guys i just have two questions about two methods used in many controllers/servlets in my app: 1-what is the difference between calling a static method in a util class or a non static method (like methods dealing with dates i.e getting current time,converting between timezones), which is better ? 2-what is the difference between calling a method(contain too many logic like sending emails) in the controller directly or running this method in a different thread ?

  • How do I serve a large file using Pylons?

    - by Chris R
    I am writing a Pylons-based download gateway. The gateway's client will address files by ID: /file_gw/download/1 Internally, the file itself is accessed via HTTP from an internal file server: http://internal-srv/path/to/file_1.content The files may be quite large, so I want to stream the content. I store metadata about the file in a StoredFile model object: class StoredFile(Base): id = Column(Integer, primary_key=True) name = Column(String) size = Column(Integer) content_type = Column(String) url = Column(String) Given this, what's the best (ie: most architecturally-sound, performant, et al) way to write my file_gw controller?

    I am having some trouble getting this simple code to work: class CreateUserView { public: CreateUserView(void); ~CreateUserView(void); UserController* controller; void showView(); string name; string lastname; string address; string email; string dateOfBirth; }; All i need is to set these attributes in the implementation with getline(). CreateUserView::CreateUserView(void) { } void CreateUserView::showView() { cout << endl << " New User" << endl; cout << "--------------------------" << endl; cout << " Name\t\t: "; getline(cin, name); cout << " Lastname\t: "; getline(cin, lastname); cout << " Email\t\t: "; getline(cin, email); cout << " ===============================" << endl; cout << " 1. SAVE 2.CHANGE 3.CANCEL" << endl; cout << " ===============================" << endl; cout << " choice: "; int choice; cin >> choice; cin.ignore(); controller->createUser_choice(choice); } I keep getting this "Access violation reading location" error at this line: getline(cin, name); what's the best way of assigning a value to an std::string attribute of a class? even name = "whatever" is throwing that error!! thanks

  • Labjack Humidity Probe Example

    - by Blindy
    I realize this might be a long shot, but does anyone have an example of using the EI-1050 probe with a Labjack controller in something C-related? I'm currently using a Labjack U12 if it matters. It installed 2 examples, ljsht and ljsht-multi, that seem to be doing something related to it, but I can't find the source code. Thank you for your time.

  • Asp.net mvc class reference in session

    - by Billy
    Hi, if I put a custom class in session, then in an action method I get an instance of that class from session, and populate some fields, I noticed that when a different controller gets that class from session, those fields are populated. Even though after the first call didn't save the updated class back in session. is this typical behavior for session objects? I thought I had to use keyword 'static' on the class in session for this to happen thanks

  • How to rotate UIViews?

    - by user717452
    The Twitter app is a tab bar app on the iPhone. Nothing in any of the tabs will rotate, yet, when you click on a link from a tweet, the view controller that is pushed on top of it IS allowed to rotate. The only rotations I have ever doe is from tilting the device, landscape or portrait, but I don't understand how to use 2d transformations and animations to rotate views. How do you rotate any view with that's a subclass of UIView?

  • Why is cakephp form input stored in $this->data and POST data stored in $this->params['form'] ?

    - by spudnik1979
    the cakephp rest tutorial says that post data should be in $this-data, but I am finding that it is not, but instead inside $this-params['form'] However, when using cakephp form helper in a view, the data is in $this-data. Am I correct to have to check both locations in my controller? It just seems a bit of a waste of extra code. Shouldnt the data appear in one place for whether it came from a rest rest requestor or Cakephp form post? ps im using cakephp 1.3

  • Use textbox value on submit as a query string variable

    - by Eric
    How would I take a text box value and use it in the query string on submit? I'd like it to start as this, /News?favorites=True and end up something like this after the user enters in a search and clicks search. /News?query=test&favorites=True The controller action looks like this public ActionResult Index(string query,bool favorites) { //search code } This question is something close to what I'd like to do, but I'd like to use the query string and maintain the existing values in the query string. Thanks.

  • ASP.NET MVC model state as text

    - by David Moorhouse
    Is there an easy way to get a summary string of the errors that have been added to a controller's modelstate? I'm looking to return this in an Ajax method and want the validation errors etc to be returned to the client (i.e. the view does not exist for this method call). Or do I have to loop through the modelstate and look at each object and extract the error text manually?
