问题 I'm programming for the iPhone and I'm wondering when to use the addSubview method of a view and when to present to use the modal view controller (presentModalViewController).

问题 With this code: public String Get(int id) { return platypi.Find(p => p.Id == id).Name; } ...I can get existing data via: http://localhost:33181/api/DPlatypus/N (where N corresponds to an existing ID).

Is there a way to safely

问题 Simple question from an absolute n00b. I'm trying to create an edit content screen based on the code given in the Blog Tutorial on the Cake site. Here's my edit function in the controller (it's named Contents): function edit( $id = null ) { $this->Content->id = $id; Debugger::dump( $this->Content->id ); if( empty( $this->data ) ) { $this->data = $this->Content->read(); Debugger::dump( $this->Content ); } else { if( $this->Content->save( $this->data ) ) { $this->Session->setFlash( 'Content has

问题 I'm working on a timesheet/actiontracker application. I'm using Spring MVC. This is my current situation: I got a form with all the tasks. Next to these tasks there are seven textboxes (which display the amount of hours for the next seven days). A user must be able to save the tasks (and the hours).
