  • What is the difference between #ifdef __IPHONE_3.2 and #if __IPHONE_3.2?

    - by Jonathan
    Hi, I have an iphone app that needs to work for 3.1.3 for the iPhone and 3.2 for the iPad. It is an iPhone app that I want to work on the iPad. The main difference is the MPMoviePlayerController which introduces/and deprecates lots of things in 3.2. Since, the iPhone OS only goes up to 3.1.3 and the iPad is on 3.2, I need to seperate my code so it only compiles the required code for the respective OS. I can't use [[UIDevice currentDevice] model] because I end up with deprecated warnings on the 3.1.3 code. Also, UIUserInterfaceIdiomPad is new in 3.2 so it doesn't work well with 3.1.3... So, I decided to use this, which only compiles what is necessary for the particular OS: #if __IPHONE _3_2 //do 3.2 iPad stuff #else //do 3.1.3 iPhone/iPod Touch stuff #endif My question is... What is the difference between these? #ifdef __IPHONE_3_2 and #if __IPHONE_3_2 Thank you

  • Formatting inline many-to-many related models presented in django admin

    - by Jonathan
    I've got two django models (simplified): class Product(models.Model): name = models.TextField() price = models.IntegerField() class Invoice(models.Model): company = models.TextField() customer = models.TextField() products = models.ManyToManyField(Product) I would like to see the relevant products as a nice table (of product fields) in an Invoice page in admin and be able to link to the individual respective Product pages. My first thought was using the admin's inline - but django used a select box widget per related Product. This isn't linked to the Product pages, and also as I have thousands of products, and each select box independently downloads all the product names, it quickly becomes unreasonably slow. So I turned to using ModelAdmin.filter_horizontal as suggested here, which used a single instance of a different widget, where you have a list of all Products and another list of related Products and you can add\remove products in the later from the former. This solved the slowness, but it still doesn't show the relevant Product fields, and it ain't linkable. So, what should I do? tweak views? override ModelForms? I Googled around and couldn't find any example of such code...

  • Calling a method from within a django model save() override

    - by Jonathan
    I'm overriding a django model save() method. Within the override I'm calling another method of the same class and instance which calculates one of the instance's fields based on other fields of the same instance. class MyClass(models.Model): field1 = models.FloatField() field2 = models.FloatField() field3 = models.FloatField() def calculateField1(self) self.field1 = self.field2 + self.field3 def save(self, *args, **kwargs): self.calculateField1() super(MyClass, self).save(*args, **kwargs) The override method is called when I change the model in admin. Alas I've discovered that within calculateField1() field2 and field3 have the values of the instance from before I edited them in admin. If I enter the instance again in admin and save again, only then field1 receives the correct value as field2 and field3 are already updated. Is this the correct behavior on django's side? If yes, then how can I use the new values within calculateField1? I cannot implement the calculation within the save() as calculateField1() actually quite long and I need it to be called from elsewhere.

  • Accessing updated M2M fields in overriden save() in django's admin

    - by Jonathan
    I'd like to use the user updated values of a ManyToManyField in a model's overriden save() method when I save an instance in admin. It turns out that by design, django does not update the M2M field before calling save(), but only after the save() is complete as part of the form save... How can I access the new values of this field in the override save() ?

  • Partial template specialization on a class

    - by Jonathan Swinney
    I'm looking for a better way to this. I have a chunk of code that needs to handle several different objects that contain different types. The structure that I have looks like this: class Base { // some generic methods } template <typename T> class TypedBase : public Base { // common code with template specialization private: std::map<int,T> mapContainingSomeDataOfTypeT; } template <> class TypedBase<std::string> : public Base { // common code with template specialization public: void set( std::string ); // functions not needed for other types std::string get(); private: std::map<int,std::string> mapContainingSomeDataOfTypeT; // some data not needed for other types } Now I need to add some additional functionality that only applies to one of the derivative classes. Specifically the std::string derivation, but the type doesn't actually matter. The class is big enough that I would prefer not copy the whole thing simply to specialize a small part of it. I need to add a couple of functions (and accessor and modifier) and modify the body of several of the other functions. Is there a better way to accomplish this?

  • How can I share variables between a base class and subclass in Perl?

    - by Jonathan
    I have a base class like this: package MyClass; use vars qw/$ME list of vars/; use Exporter; @ISA = qw/Exporter/; @EXPORT_OK = qw/ many variables & functions/; %EXPORT_TAGS = (all => \@EXPORT_OK ); sub my_method { } sub other_methods etc { } --- more code--- I want to subclass MyClass, but only for one method. package MySubclass; use MyClass; use vars qw/@ISA/; @ISA = 'MyClass'; sub my_method { --- new method } And I want to call this MySubclass like I would the original MyClass, and still have access to all of the variables and functions from Exporter. However I am having problems getting the Exporter variables from the original class, MyClass, to export correctly. Do I need to run Exporter again inside the subclass? That seems redundant and unclear. Example file: #!/usr/bin/perl use MySubclass /$ME/; -- rest of code But I get compile errors when I try to import the $ME variable. Any suggestions?

  • UIControlEventTouchDragExit only fires ~100 pixels out

    - by Jonathan
    Im trying to "get" when a finger/touch leaves a UIButton in objective C for iphone. I was told in another answer to use UIControlEventTouchDragExit however this event only fires when the touch gets about 100 pixels away from the button, whereas I would like it to be immediate. The apple docs say that goes according to the bounds however my understand is the bounds and the frame are the same unless you rotate the UIbutton (or whatever)

  • silverlight for .NET / CLR based numerical computing on osx

    - by Jonathan Shore
    I'm interested in using F# for numerical work, but my platforms are not windows based. Mono still has a significant performance penalty for programs that generate a significant amount of short-lived objects (as would be typical for functional languages). Silverlight is available on OSX. I had seen some reference indicating that assemblies compiled in the usual way could not be referenced, but not clear on the details. I'm not interested in UIs, but wondering whether could use the VM bundled with silverlight effectively for execution? I would want to be able to reference a large library of numerical models I already have in java (cross-compiled via IKVM to .NET assemblies) and a new codebase written in F#. My hope would be that the silverlight VM on OSX has good performance and can reference external assemblies and native libraries. Is this doable?

  • Special characters in PHP / MySQL

    - by Jonathan
    Hi, I have in the database words that include special character (in Spanish mostly, like tildes). In the database everything is saved and shown correctly with PHPmyAdmin, but when I get the data (using PHP) and display it in a browser, I get a weird character, like a "?" with a square... I need a general fix so I don't need to escape each character every time, and also I would be able to insert special Spanish characters from a PHP form into the database... The HTML is correct: <meta http-equiv="content-type" content="text/html; charset=utf-8" /> All tables and databas are set to utf8_spanish The character I get: ? Any suggestions??? Thanks!!!

  • Playing a .TS file on iOS

    - by Jonathan Grynspan
    We're working with some hardware that produces files in the .TS format, and we'd like to play them on an iOS device. (The files are internally consistent with what iOS supports--MPEG-4 video, AAC audio.) We've been investigating three options so far: Roll our own integrated HTTP Live Streaming server and serve up a faux M3U8 playlist from within the app. This... doesn't seem to want to play nice, and we've had mixed luck actually getting the .TS files to play on devices. Unwrap the MPEG-4 and AAC data from the TS file and re-wrap it as MP4. This, I'm told, is exceedingly difficult to do, and I haven't found anything useful online that could shed light on how to do it. We've got code in the pipeline to do it but it won't be ready until long after we need it. If we could do it, I could easily subclass NSURLProtocol and have it working within a matter of hours minutes. Use FFmpeg to implement option #2. FFmpeg seems like a possible solution but it isn't configured to build for iOS and I don't have the background to get it working (whereas the rest of our engineers don't have the Apple background needed.) I think #2 is our best bet, but as I don't know the ins and outs of MPEG-2 TS and MPEG-4, I don't have the ability to put it together myself. Does anybody have any insight into this problem? Perhaps some experience playing local TS files on iOS, or some tips on converting from TS to MP4?

  • Visual Source Safe on Mac OS X

    - by Jonathan Badeen
    Is there an application or API for using/accessing Visual SourceSafe (6.0) under Mac OS X? I'm currently using VSS Connect under Parallels for working with our company's ASP.NET site/s. I currently have my Windows drive shared and try to use TextMate on the Mac side to actually edit files. It would be nice to have the ability to check files in/out outside of my virtual machine though.

  • Preventing the opening of a form on a add button click

    - by Jonathan
    Hey guys, Did you guys know how to prevent the open of a Form when I click on a add button? Maybe using beforeShowForm? function(formid) { if(jQuery('#gridap').getGridParam('selrow')) { idgridap=jQuery('#gridap').getGridParam('selrow'); jQuery('#FK_numerocontrato_ap',formid).val(idgridap).attr('readonly','readonly'); } else { // I want to prevent the openning of the add form here and maybe show an alert using the "alertcap" } } CHECAROW; $grid->setNavEvent('add','beforeShowForm',$checarowid); BTW, there's a way to call the alertmod of jqgrid and add a custom message to it? tks!

  • How to find Part Time development/IT work?

    - by Jonathan
    I've been working in the IT field now for 10 years. Originally trained as an Engineer, started out with C++ and have been a .Net specialist since beta. Currently seconded to a major city and working in the finance industry as freelance, I really feel like i've hit the glass ceiling. Have been contracting now for 5 years as the company politics and frustration of not being promoted and poor pay rises for excellent work but during the last decade of corporate cost cutting took its toll on my morale. Freelance made all the difference and i've had a very decorated career for good clients. What any Engineering student could ever dream of when starting out. The problem is, it doesn't particularly make me happy. It's good work, and i enjoy the problem solving aspects of it and having something to do each day. However there is always a large overhead of non-technical work and dealing with poor managers etc. I guess the Engineering was always a bit of a mistake i made the best out of, and now having 10 years behind a computer hasn't done wonders for my health or eye sight. In a nutshell i am in the process of retraining as a therapist and would like to open my own clinic. However, never having done this before, the fast pace IT skills outdate and the fact that all my experience and skills are non transferrable, i am a little worried. Any ideas how i can find part time IT work as i build up my business? (it's incredibly hard to find freelancing work that doesn't require long hours and overtime). Or other ideas to make the transition easier, and perhaps backout if it financially doesn't work/or i have enough marketing skills? I'd be interested to hear from people who have made a similar transition, successfully or unsuccessfully. Many thanks

  • Generating video or images of geometrical objects from data

    - by Jonathan Barbero
    Hello, I'm working in a course's project to predict the velocity and position of the solar system planets (and other objects). It will be really cool if I can visualize the predicted objects data, if it's possible generating 3D images, if in video that's amazing. Do you know any library that lets me to use this data to generate an image or video? (I don't care in which language) Data: - simulation step (time line step for a video) - positions of the objects - radius and/or colours of the objects Thanks in advance, any suggestion is welcome.

  • Does Resharper 4.1 support both Camel Humps and normal selection modes?

    - by Jonathan Parker
    I've found the setting for Camel Humps in resharper: Resharper - Options - Editor - Use CamelHumps The problem is that I would still like to be able to use the normal selection mode (i.e. the default behaviour for CTRL+Arrow and CTRL+SHIFT+Arrow) as well as the CamelHumps mode. For example consider this variable: private int MyVeryLongCamelCaseName; Now if I want to copy the entire variable then I want the VS default behaviour for CTRL+SHIFT+Left-Arrow which is to select the entire variable if the cursor is on the M. However if I want to change the name to say MyExtremelyLongCamelCaseName then I would like the CamelHumps behaviour provided by Resharper. Is there any way to have both behaviours with different shortcuts?
