    Am I allowed to do two queries one by one or can I squeeze both these operations into one query. PDO wasn't working so I used brute force and it both insertions and deletes work, but now I want to order them.
    $q="INSERT INTO scheduler VALUES ('$custnum', NULL, '$day', '$starttime', '$mode', '$temp', '$humid', '$duration', '$air_quality', '$fresh_air')";
    $result=mysql_query($q) or die ("query submission error:".mysql_error());
    
    $o = "SELECT * FROM scheduler ORDER BY day";
    $result=mysql_query($o) or die ("query submission error:".mysql_error());
    

    Also, I can successfully order by day via phpmyadmin because I changed the seven days of the week to integers, but the user still sees "Mon, Tue, Wed" and so on by matching the integer with an array like so.
    $days=array ('null','Mon','Tue', 'Wed', 'Thur', 'Fri', 'Sat', 'Sun');
    //skipping rows....
    echo '<td>'. $days[$row['day']] .'</td>';

    Holy shit.

    I ran across some code where it looks like someone attempted some templating generics but would've been far better if they used polymorphism. In particular it looks like someone had adapted this code to be multi-database but instead of having a base interface in which to derive from, the class has like 4-5 different types of variables.

    Something like:
    public enum SQLType
    {
      SQLServer,
      MySQL,
      //there's a few in here
      //only those two were implemented
    }
    
    public class DatabaseLinker
    {
      //defaults to SQL Server
      private SqlType type = SQLType.SQLServer;
    
      private MySqlConnection my_cn;
      private SqlConnection cn;
    
      private MySqlCommand my_cmd;
      private SqlCommand cmd;
      //... so on
    
      //wat????
      public SqlDataReader GetReader() {
              return dr;
      }
    
      public MySqlDataReader GetReader() {
          return my_dr;
      }
    }
    

    Oh yeah... and that's my cleaned up version of the mess they had.

    Oh whoops I messed up something there on line 21. I must've missed something in a signature when I was cleaning it up too, because that shouldn't work/compile at all, I don't think, at least I don't think it does in .NET.

    Then what I did was, rather than put the ORDER BY after my submissions and deletions, I went to the page displaying the database contents, and put my ORDER BY in front of the select. Rather than try to order the database itself, it grabs everything from the database, then orders it for the user's purposes. This did the trick.

    Man, .Net reflection is dizzying. I just reflected over an arbitrary number of types that have some attribute we created that specifies a MenuStrip (WinForms control) is present in that class. I then used reflection to get that MenuStrip and iterated over the MenuItems, stripping useful properties from each one to stuff into a new data model we've been mandated to move to. Oh, I also grabbed MenuItem.PerformClick() and wrapped it as an Action so that when they click WPF elements in the new UI we can fire the old Action without even knowing what it was.


    I feel dirty.

    Well at least you aren't cleaning up this code with it's wonderful ambiguous template-style system that I'm worried about has been functioning properly.

    So, if you need to refactor a model from one django app out into a new one and are trying to use South for migrations it's kind of a nightmare. I'm so glad this system is early enough in development and not live anywhere so that "Drop the db and recreate it. Sorry about the test data loss." was acceptable.

    Okay I'm going to ask this here, because it seems appropriate. I'm working on a project, and I need to modify someone else's code slightly. A little, minor change. The only problem is that he used Boost, and Boost refuses to properly install or something. I tried installing it from scratch, and I tried using BoostPro. I don't see what I can be doing wrong as I followed a guide, and BoostPro has like three checkboxes that you fill in appropriate to your IDE. I'm using VS9/2008.

    When I try to compile, Boost explodes with all sorts of errors, here's an excerpt: http://pastebin.com/qJdQ8w2X

    I really want to continue working on my project. Does anybody have any idea what is going on? I've asked in Boost's IRC channel, but it's surprisingly idle and the only answers I've gotten are "You did it wrong. Do it again." I've done it four times now, tried compiling from scratch following a guide, and BoostPro has like three checkboxes - there's no way to screw it up.

    Those lines look like they're referring to C++0x features:

    e.g.
    #if defined( BOOST_HAS_RVALUE_REFS )
    
        template<class Y>
        weak_ptr & operator=( weak_ptr<Y> && r ) // <---- Line 137 here
        {
            this_type( static_cast< weak_ptr<Y> && >( r ) ).swap( *this );
            return *this;
        }
    
    #endif
    
    

    From what I can tell, VS2008 does not support C++0x.

    It looks like something is telling boost to use C++0x features, because those lines are only compiled if BOOST_HAS_RVALUE_REFS is defined.

    I guess if you want to keep on using VS2008, you could try to find out what is causing C++0x features to be turned on?

    Okay guys I have a question about drag and dropping.

    I've added a DropTargetListener to a control that we have. Using system.out.println() I know that it is working properly (if something drags over it the listener outputs correctly). Now the real issue is I need to figure out how to get the data of the dragged event. I see that the following method exists:
    public void drop(DropTargetDropEvent dtde){
    }
    

    Is the data hidden behind the dtde? Or am I going about this all wrong?

  • bowenbowen Registered User regular
    edited April 2012
    You'll probably want to determine the type of object (image, string, whatever) from the dtde.getCurrentDataFlavors() of the event, and then use dtde.getTransferrable() on the to get the actual object once you determine what type it is and how to manage it.

    bowen on
  • urahonkyurahonky Registered User regular
    Okay this is weird. Whenever I drag and drop something into our editor window the drop target drop event doesn't have any data flavors.

  • urahonkyurahonky Registered User regular
    edited April 2012
    Even weirder. It works when I call the dtde immediately after the drop, but when I pass that event into another class I lose the data flavors. I don't understand why that is.

    e: Turns out we don't really use the dtde for anything other than the location. Sigh..

    Say you drag and drop something. This dtde event gets stored into a private variable. This variable is passed into another class. And then this is called again, but somehow the DataFlavors don't exist.

    But I figure I'm just going to follow what we did before.

    FYI, when using b2/bjam to build Boost for MSVC you need to specify the toolset and the version number (VS2008 == 9.0, so msvc-9.0).

    Just for my own knowledge is it possible to mirror a class to another name (C#)?

    Let's say I have class foo:
    public class Foo 
    {
        public void SayHello() {
            Console.WriteLine("Hello!");
        }
    }
    

    Is it possible to make a global mirror so I can do something like
    public class Bar : Foo; //(MIRRORS FOO)
    
    int main()
    {
        //call one of Foo's constructor's through Bar
        //and SayHello
        Bar myBar = new Bar();
        myBar.SayHello();
    }
    

    The class name I have to be calling is ugly as shit and I was hoping for an easy way to do this without having to have a statement in each file or something, something I can do globally.

    So I really like some of the stuff Notch is doing with programmability in games with his 0x10^C stuff. Ever since playing FF12, and later Dragon Age, and seeing the complex gambit/AI systems they had, that were essentially visual scripting systems, I've been thinking about putting a much more advanced AI scripting system in my game...it's super niche, but I think niche sells in the indie space, and frankly I am more worried about writing something I'd play and have fun with, than making a ton of cash.

    My big question is if I should use an off the shelf language, that may be off putting to really new users, or if I should roll something simple and BASIC'y that is really easy for non-programmers to try and pick up. I think it would be really neat to have my game be used as a way for younger/newer scripters to learn how to write good AI code. Would be really cool to see people passing around AI scripts for different party members.

    Off the shelf language means you are writing an API, not a scripting system. For things to be simple enough for non-developers, you want that BASIC'y limitation on what they can do to (a) keep them on task and (b) make it a lot more straight-forward.

    Something where the interactions and processes are visible is the key to usability. Even programmers have fun with a custom scripting language in games so it works for everyone.

    That shouldn't be too hard. I recall there was some trick to creating an interpreter really quickly, like in the matter of a day.

    I have since forgotten that trick.

    I've written them in the past, it's not real difficult. I'll probably use Antlr to write the parser, as it has a C# interface, and makes things really nice to do in terms of Parser BNF -> AST -> Byte Code.

    Being able to assume a lot of context is what makes scripting friendly and intuitive.

    I had a lot of fun with ZZT/Megazeux back in the day. Take a look at the code, it is short but event-message driven and uses a lot of builtins to make interfacing with your game world easy.

    I would recommend something a little more up to date though in style. :lol:

    I used the Microsoft Press Self-Paced Training Kit book to study for that test. When I took the test it was all just test questions, there weren't any lab simulator questions like the SQL 2005 test had.

    By now the SQL 2012 tests are probably available, so unless you specifically need the 2008 version you may want to look at the newer exams.
