  • Calling a method from another view in objective-c. (iphone sdk).

    - by MarcZero
    Hello. I am currently creating a multi-view game on the iPhone platform. I have my main view start to play some background music upon loading. I then go to another view and start the game. I am trying to get the background music from the original view to stop once I start the game. I am having trouble getting the stop playing music message to my original view. Here is the relevant info: The main view where the sound is played from is just a subView of the programViewController class called *viewController. The heading is in the programAppDelegate class. The sound is done using the AVAudioPlayer class and plays fine when the program starts up and when I navigate to other subviews that are added on by going through the menu system. In the view that I want to start the game, I attempt to call the instance of the class to turn of the player but anytime I use this format of code: [viewController #######]; It gives a build error of "viewController undeclared" no matter what I put after the "viewController" in the message.I have attempted to import the programAppDelegate.h file but it still gives the same error. I realize this might be a simple misunderstanding of the objective-c language but I cannot find any info on this issue. I am a recent convert from Java so I am trying to wrap my head around everything. Thank you for your time!

  • "Remember" last three MySql queries; Cookie, passed variable or other method?

    - by Camran
    I have a classified website, with pretty sophisticated searching, and I am about to implement a function where the last three queries is displayed for the user, so that the user can go back easier through the queries. This because for each query the user has to provide a lot of input. I have four questions for you: I wonder, how can I save the actual query (SELECT * FROM etc etc)...? Do I need to add some form of encryption to be on the safe side? How will this affect performance? (I don't like the fact that cookies slow websites down) Anything else to think about? If you need more input, let me know... Btw, the website is PHP based. Thanks

  • Grails: No tag library for namespace. Cannot use any plugins with custom taglibs.

    - by user312435
    I can't seem to use any of the grails ui plugins such as richui or grails-ui. I used grails install-plugin to install them, and grails list-plugins shows that they are correctly installed. However, whenever I use their provided taglibs in my views, I get this exception: Tag [tabview] does not exist. No tag library found for namespace: gui or Tag [tabview] does not exist. No tag library found for namespace: richui I'd really like to use these features, but cannot figure out how to get grails to recognize that the tag libraries are installed.

  • How to use Jquery UI in my Custom Function? (Autocomplete)

    - by bakazero
    I want to create a function to simplify configuration of jQuery UI AutoComplete. Here is my function code: (function($) { $.fn.myAutocomplete = function() { var cache = {}; var dataUrl = args.dataUrl; var dataSend = args.dataItem; $.autocomplete({ source: function(request, response) { if (cache.term == request.term && cache.content) { response(cache.content); } if (new RegExp(cache.term).test(request.term) && cache.content && cache.content.length < 13) { var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i"); response($.grep(cache.content, function(value) { return matcher.test(value.value) })); } $.ajax({ url: dataUrl, dataType: "json", type: "POST", data: dataSend, success: function(data) { cache.term = request.term; cache.content = data; response(data); } }); }, minLength: 2, }); } }) (jQuery); but when I'm using this function like: $("input#tag").myAutocomplete({ dataUrl: "/auto_complete/tag", dataSend: { term: request.term, category: $("input#category").val() } }); It's give me an error: Uncaught ReferenceError: request is not defined

  • Is there a way to catch an attempt to access a non existant property or method?

    - by Tor Valamo
    For instance this code: function stuff() { this.onlyMethod = function () { return something; } } // some error is thrown stuff().nonExistant(); Is there a way to do something like PHP's __call as a fallback from inside the object? function stuff() { this.onlyMethod = function () { return something; } this.__call__ = function (name, params) { alert(name + " can't be called."); } } // would then raise the alert "nonExistant can't be called". stuff().nonExistant();

  • Why does the Win32-API have so many custom types?

    - by sub
    I'm new to the Win32 API and the many new types begin to confuse me. Some functions take 1-2 ints and 3 UINTS as arguments. Why can't they just use ints? What are UINTS? Then, there are those other types: DWORD LPCWSTR LPBOOL Again, I think the "primitive" C types would be enough - why introduce 100 new types? This one was a pain: WCHAR* I had to iterate through it and push_back every character to an std::string as there wasn't another way to convert it to one. Horrible. Why WCHAR? Why reinvent the wheel? They could have just used char* instead, or?

  • Can't pass and retrieve CharSequence to another activity using intent.getExtras() method.

    - by vt
    Activity 1: Intent i = new Intent(this, Activity2.class); CharSequence btText = btButton.getText(); i.putExtra(BUTTON_TEXT, btText); startActivityForResult(i, ACTIVITY_SETTINGS); Activity 2: in onCreate: Bundle extras = getIntent().getExtras(); if (extras != null) { mButtonText = extras.getCharSequence(Activity1.BUTTON_TEXT); } The resulting CharSequence is not what was passed, it's something like "(id=830066506776)" instead. This works: CharSequence test2 = getIntent().getCharSequenceExtra(Activity1.BUTTON_TEXT); What is wrong with getExtras approach? This is what they used in Notepadv3 example. This is for Android 2.1. Thank you.

  • Efficient method of finding database rows that have *one or more* qualities from a list of seven qualities

    - by hithere
    Hello! For this question, I'm looking to see if anyone has a better idea of how to implement what I'm currently planning on implementing (below): I'm keeping track of a set of images, using a database. Each image is represented by one row. I want to be able to search for images, using a number of different search parameters. One of these parameters involves a search-by-color option. (The rest of the search stuff is currently working fine.) Images in this database can contain up to seven colors: -Red -Orange -Yellow -Green -Blue -Indigo -Violet Here are some example user queries: "I want an image that contains red." "I want an image that contains red and blue." "I want an image that contains yellow and violet." "I want an image that contains red, orange, yellow, green, blue, indigo and violet." And so on. Users make this selection through the use of checkboxes in an html form. They can check zero checkboxes, all seven, and anything in between. I'm curious to hear what people think would be the most efficient way to perform this database search. I have two possible options right now, but I feel like there must be something better that I'm not thinking of. (Option 1) -For each row, simply have seven additional fields in the database, one for each color. Each field holds a 1 or 0 (true/false) value, and I SELECT based on whatever the user has checked off. (I didn't like this solution so much, because it seemed kind of wasteful to add seven additional fields...especially since most pictures in this table will only have 3-4 colors max, though some could have up to 7. So that means I'm storing a lot of zeros.) Also, if I added more searchable colors later on (which I don't think I will, but it's always possible), I'd have to add more fields. (Option 2) -For each image row, I could have a "colors" text field that stores space-separated color names (or numbers for the sake of compactness). Then I could do a fulltext match against search through the fields, selecting rows that contain "red yellow green" (or "1 3 4"). But I kind of didn't want to do fulltext searching because I already allow a keyword search, and I didn't really want to do two fulltext searches per image search. Plus, if the database gets big, fulltext stuff might slow down. Any better options that I didn't think of? Thanks! Side Note: I'm using PHP to work with a MySQL database.

  • How do I set the dimensions of a custom component defined in an ActionScript class?

    - by user339681
    I'm trying to set the height of a vertical bar (activityBar) but it does not appear to do anything. i have tried something similar with the whole component, but setting the dimensions does nothing (even in the mxml used to instantiate the class). Indeed, I've added transparent graphics just to give the component some dimensions I'm not sure what I'm doing wrong. It's something bad though; my approach seems dire. FYI: I'm trying to create a mic activity bar that will respond to the mic by simply setting the height of the activityBar child (which seems to me to be more efficient than redrawing the graphics each time). Thanks for your help! package components { import mx.core.UIComponent; public class MicActivityBar extends UIComponent { public var activityBar:UIComponent; // Constructor public function MicActivityBar() { super(); this.opaqueBackground = 0xcc4444; graphics.beginFill(0xcccccc, 0); graphics.drawRect(0,-15,5,30); graphics.endFill();// background for bar activityBar = new UIComponent(); activityBar.graphics.beginFill(0xcccccc, 0.8); activityBar.graphics.drawRect(0,-15,5,20); activityBar.graphics.endFill(); activityBar.height=10; addChild(activityBar); } } }

  • How to deal with delegate method calling back the object who send the message ?

    - by olipion
    I have two object: @protocol ObjectADelegate - (void)objectAfirst:(ObjectA *)obj; - (void)objectAsecond:(ObjectA *)obj; @end @interface ObjectA : NSObject { id<ObjectADelegate> delegate; - (void)callSecond { [self.delegate objectAsecond:self]; } @end @interface ObjectB : NSObject <ObjectADelegate>{ ObjectA *myObjectA; } @implementation ObjectB - (void)objectAfirst:(ObjectA *)obj { // First is finished, do second [obj callSecond]; } - (void)objectASecond:(ObjectA *)obj { // Do my stuff } @end As you can see in the code, when ObjectA send the message objectAfirst to its delegate, objectb use again objectA methods that result in objecta calling back objectb. It means that what first fire objectAfirst is not finished but objectA send the objectAsecond message. Could it be a problem ? Any way to let delay message handling in objectB ? for example, something like using [obj performSelector:@selector(callSecond) afterDelay:0.01]; instead of [obj callSecond]; ?

  • Making a char function parameter const?

    - by Helper Method
    Consider this function declaration: int IndexOf(const char *, char); where char * is a string and char the character to find within the string (returns -1 if the char is not found, otherwise its position). Does it make sense to make the char also const? I always try to use const on pointer parameters but when something is called by value, I normally leave the const away. What are your thoughts?

  • How can i access my custom webpart in sharepoint foundation 2010?

    - by oklahoma_overlord
    Hi, So i just started trying to develop a simple webpart today for a sharepoint foundation i put on a virtual machine. I have no previous experience with sharepoint whatsoever. As i cant run a sharepoint 2010 on my local machine for dev purposes i followed advices in this thread http://social.technet.microsoft.com/Forums/en/sharepoint2010programming/thread/cda807f6-4edf-4efc-8e9b-4d446356c8ae to able to actually develop something (just the registry bit). I created the simple test web part (writes out "hi"), uploaded it to virtual machine, added it with add-spsolution and install-spsolution in powershell with success. When i do get-solution through powershell on my webpart it says deployed = true. What am i missing from here to get it to actually show up somewhere in the web interface so i can add it to a page? Cheers

  • Any point in subclassing UIButton to create a custom looking button?

    - by glitch
    I want to create a set of buttons that would work and feel very much like the Metro-style tiles that are available on Windows Phones. I would like to allow the user to tap them to access their underlying functionality (open a modal or something or that sort). I'm concerned that subclassing UIButton will not get me there. I need square corners and dynamic content inside the tiles themselves. The posts I've found around SO seem to suggest that subclassing a UIButton would not be a good idea for several reasons and that I should instead use UIView. That reply is from 2010, and I have no idea if in the 2+ years since then there have been considerable changes to how one would achieve that effect. Most users these days will have iOS 5.1+ if not 6.0 soon. Let's say I do go the UIView route. Should I implement UIResponder's touch events or should I instead go the UITapGestureRecognizer route? What's the better practice in 2012? Thank you!

  • How to call a method on UIButton in NSArray?

    - by user1792818
    I'm trying to enable a button but the button that I would enable in this function changes. I have an array of the buttons but when I use the .enabled on the array index I want it says that this doesn't work for IDs. I have used this array to set the text of each button before using: [[ButtonArray objectAtIndex: Index] setTitle:(@"blahblahblah") forState: UIControlStateNormal]; is there any way to use a similar function call to enable and disable?

  • How do I create a dynamic method in PHP?

    - by sandelius
    I'm trying to extend my ActiveRecord class with some dynamic methods. I would like to be able to run this from my controller $user = User::find_by_username(param); $user = User::find_by_email(param); I've read a little about overloading and think that's the key. I'v got a static $_attributes in my AR class and I get the table name by pluralizing my model (User = users) in this case. How do I do this? All models extends the ActiveRecord class.
