    - by L.J.W
    Hi all, I have a question about invoking air in air,please give me some advice. I want to use air technology in enterprise business,and I think widget manager(engine) like google desktop,vista sidebar is a good system entrypoint.so I look for a widget manager basing AIR,the widget manager can load air widget, and auto upgrade widget silently ,and have a cool user-interface like google desktop or vista sidebar or yahoo's. Any product existed and recommend?and if I need to implement myself,any idea or advice?How can I embed the widget interface into the manager(engine) interface seamless,how can I invoke the specified window(maybe not the init window) in the widget air application from the manager? Thanks and best regards

  • Sorting an NSArray of NSString

    - by Robert Eisinger
    Can someone please show me the code for sorting an NSMutableArray? I have the following NSMutableArray: NSMutableArray *arr = [[NSMutableArray alloc] init]; with elements such as "2", "4", "5", "1", "9", etc which are all NSString. I'd like to sort the list in descending order so that the largest valued integer is highest in the list (index 0). I tried the following: [arr sortUsingSelector:@selector(compare:)]; but it did not seem to sort my values properly. Can someone show me code for properly doing what I am trying to accomplish? Thanks!

  • How to reuse actions

    - by Kriem
    Of the three parts I want to move, only the last one actually moves. I can't seem to "recycle" the ease action I created. How is this done the correct way? - init { // initial setup [self moveParts]; } - (void)moveParts { id action = [CCMoveBy actionWithDuration:1 position:ccp(0,160)]; id ease = [CCEaseInOut actionWithAction:action]; [part1 runAction:ease]; [part2 runAction:ease]; [part3 runAction:ease]; }

  • Append all logs to /var/log

    - by iCy
    Application scenario: I have the (normal/permanent) /var/log mounted on an encrypted partition (/dev/LVG/log). /dev/LVG/log is not accessible at boot time, it needs to be manually activated later by su from ssh. A RAM drive (using tmpfs) is mounted to /var/log at init time (in rc.local). Once /dev/LVG/log is activated, I need a good way of appending everything in the tmpfs to /dev/LVG/log, before mounting it as /var/log. Any recommendations on what would be a good way of doing so? Thanks in advance!

  • Obj-C: Creating an object with a String name

    - by FnGreg7
    Hey all. I know this sounds simple, but I can't find a way to do it. I have a method in Obj-C that takes in a NSString and then should create a new class with the String as its title. -(DataModel *)createDataModel:(NSString *)dataModel_name { DataModel *[initWithString:dataModel_name] = [[DataModel alloc] init]; } I know I have some problems in this. For starters, I don't know how to define a return on an object whose name could change. Second, I know this doesn't compile considering the initWithString method is wrong. I just don't know what to do or what method to use so that I can create this DataModel object with the specified name...

  • Why is this Python class copying another class contents?

    - by fjfnaranjo
    Hello guys. I'm trying to understand an estrange behavior in Python. I have the next python code: class IntContainer: listOfInts = [] def __init__(self, initListOfInts): for i in initListOfInts: self.listOfInts.append(i) def printInts(self): print self.listOfInts if __name__ == "__main__": intsGroup1 = [1,2,3,4] intsGroup2 = [4,5,6,7] intsGroups = [intsGroup1,intsGroup2] intsContainers = [] for ig in intsGroups: newIntContainer = IntContainer(ig) intsContainers.append(newIntContainer) for ic in intsContainers: print ic.listOfInts I expect to get something like: [1, 2, 3, 4] [4, 5, 6, 7] But i get: [1, 2, 3, 4, 4, 5, 6, 7] [1, 2, 3, 4, 4, 5, 6, 7] I have check the next question: http://stackoverflow.com/questions/1876905/why-is-python-reusing-a-class-instance-inside-in-function And a lot of Python reference, but I can not understand what is happening. I think is related with the newIntContainer identifier reutilization, but I do not understand it deeply. Why Python appears to reused the last reference for the new object, even if I have added it to a permanent list? What can I do to resolve this behavior? Thanks ;)

  • Can't access UI from a delegate?

    - by Nick Brooks
    I got this code: GrooveOnDownload *dlg = [[GrooveOnDownload alloc] init]; NSURLDownload *dw = [[NSURLDownload alloc] initWithRequest:request delegate:dlg]; It starts the download in a delegate class with outlets for UI controls. But for some reason controls don't respond to direct messages from the delegate. //Header of the delegate @interface GrooveOnDownload : NSObject { IBOutlet id downloadButton; //... //Implementation //... [downloadButton setEnabled:FALSE]; // Doesn't work //... Any ideas?

  • How to implement a set ?

    - by nomemory
    I want to implement a Set in C. Is it OK to use a linked list, when creating the SET, or should I use another approach ? How do you usually implement your own set (if needed). NOTE: If I use the Linked List approach, I will probably have the following complexities for my operations: init : O(1); destroy: O(n); insert: O(n); remove: O(n); union: O(n*m); intersection: O(n*m); difference: O(n*m); ismember: O(n); issubset: O(n*m); setisequal: O(n*m); O(n*m) seems may be a little to big especially for huge data... Is there a way to implement my Set more efficient ?

  • Object for storing strings in Python

    - by evg
    class MyWriter: def __init__(self, stdout): self.stdout = stdout self.dumps = [] def write(self, text): self.stdout.write(smart_unicode(text).encode('cp1251')) self.dumps.append(text) def close(self): self.stdout.close() writer = MyWriter(sys.stdout) save = sys.stdout sys.stdout = writer I use self.dumps list to store data obtained from prints. Is there a more convenient object for storing string lines in memory? Ideally I want dump it to one big string. I can get it like this "\n".join(self.dumps) from code above. May be it's better to just concatenate strings - self.dumps += text?

  • How do I get the icons of TinyMCE to show?

    - by ggfan
    I installed TinyMCE and I have the textbox and the functions work(such as , ) but I don't see the tool box that has displays all the functions. Like in this example. How do I get the images to show? All I have is the textbox. I used the code from the example link and theirs has the images and all I have is the textbox. What part do I edit to be able to see the icons? //my source link <script type="text/javascript" src="/tinymce/jscripts/tiny_mce/tiny_mce.js"> tinyMCE.init({ // Example content CSS (should be your site CSS) content_css : "style12.css", // Drop lists for link/image/media/template dialogs template_external_list_url : "/tinymce/examples/lists/template_list.js", external_link_list_url : "/tinymce/examples/lists/link_list.js", external_image_list_url : "/tinymce/examples/lists/image_list.js", media_external_list_url : "/tinymce/examples/lists/media_list.js",

  • Any method to denote object assignment?

    - by Droogans
    I've been studying magic methods in Python, and have been wondering if there's a way to outline the specific action of: a = MyClass(*params).method() versus: MyClass(*params).method() In the sense that, perhaps, I may want to return a list that has been split on the '\n' character, versus dumping the raw list into the variable a that keeps the '\n' intact. Is there a way to ask Python if its next action is about to return a value to a variable, and change action, if that's the case? I was thinking: class MyClass(object): def __init__(*params): self.end = self.method(*params) def __asgn__(self): return self.method(*params).split('\n') def __str__(self): """this is the fallback if __asgn__ is not called""" return self.method(*params)

  • Mysql Connection Error from 1.1.1 to 1.2.1

    I upgraded from 1.1.1 to 1.2.1 and I seem to be getting the following exception when it attempts to connect to MySQL: The last packet sent successfully to the server was 0 milliseconds ago.

The following is the line from my application.conf file (with user/pass/db replaced): db=mysql:username:password@databasename I also tried using the full JDBC configuration. Did I miss something? This worked just fine in 1.1.1. I'm running MySQL 5.1.41. Thanks.

  • UIActionsSheet text shadow problem

    - by AlexVogel
    I have a problem with the text shadow of the UIActionSheet buttons. At iOS 4.0.2 long string were truncated automatically. No at iOS 4.2 these texts are presented with a smaller font. But now the offset of the shadow is corrupted and to big. Is there a possibility to change/remove the text shadow of the UIActionSheet. EDIT: I'm building the UIActionSheet not with initWithTitle:, but with the normal init and sets all needed properties afterwards because the number of possible buttons is dynamic and the texts cannot be change. I've tested it with initWithTitle: and got the same results.

  • Windows Form Components Access

    - by rxm0203
    What is the best way to access components (e.g. imagelist, timer) from a form instance? I am working on multi form windows forms application on .NET Compact Framework version 3.5 SP1 with C#. I have a Controller class associated with each form for MVC implementation. Here is my sample Controller class. public class Controller { public void Init(Form f) { //f.Controls will allow access to all controls //How shall I access imagelist, timer on form f. } } My question is how can I access non visual components without taking a performance hit of reflection? Any code snippets are welcome. If reflection is only way, then can you provide me optimal way for components access please? Thanks,

  • Objective-C retain clarification

    - by Maverick
    I'm looking at this code: NSMutableArray *controllers = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < kNumberOfPages; i++) { [controllers addObject:[NSNull null]]; } self.viewControllers = controllers; [controllers release]; Later on... - (void)dealloc { [viewControllers release]; ... } I see that self.viewControllers and controllers now point to the same allocated memory (of type NSMutableArray *), but when I call [controllers release] isn't self.viewControllers released as well, or is setting self.viewControllers = controllers automatically retains that memory?

  • Pagination - Symfoy

    - by user390426
    Hi I have the following code: public function executeList() { $c = new Criteria(); $c->setLimit(5); $this->latest = ItemPeer::doSelectLatest($c); } Now I'd like to be able to use pagination with this, using sfPropelPager. How could I use that with the code above, making sure It paginates results from the peer method? Thanks EDIT: Got it working: $pager = new sfPropelPager('Item', 10); $pager->setPage($request->getParameter('page', 1)); $pager->setPeerMethod('doSelectLatest'); $pager->init(); $this->pager = $pager; Thanks!

  • TinyMCE is making my code valid, and I want it to stop! (<img> tag wrapped in <p>)

    - by hookedonwinter
    I have TinyMCE installed on the back end of a site. Some of the html it's accessing isn't totally valid, which I realize is the problem in itself. However, TinyMCE is messing things up by making things valid. I have an <img> with no parents (no <p>, no <div>, etc), and TinyMCE is wrapping the <img> in <p></p>. I'm trying to find a setting that will stop that from happening. Essentially, I want TinyMCE to allow <img> to be it's own element, rather than a child element, if that makes sense. My current settings are: tinyMCE.init({ theme : "advanced", mode : "textareas", relative_urls : false });

  • How can I compare two dates, return a number of days.

    Hi, how can I compare two dates return number of days. Ex: Missing X days of the Cup. look my code. NSDateFormatter *df = [[NSDateFormatter alloc]init]; [df setDateFormat:@"d MMMM,yyyy"]; NSDate *date1 = [df dateFromString:@"11-05-2010"]; NSDate *date2 = [df dateFromString:@"11-06-2010"]; NSTimeInterval interval = [date2 timeIntervalSinceDate:date1]; //int days = (int)interval / 30; //int months = (interval - (months/30)) / 30; NSString *timeDiff = [NSString stringWithFormat:@"%dMissing%d days of the Cup",date1,date2, fabs(interval)]; label.text = timeDiff; // output (Missing X days of the Cup)

  • Accessing primitive properties from objects stored in a NSDictionary

    - by ChrisS
    Apologies if this is a basic question, I am just starting with Objective-C and trying to wrap things around in my head! I have a simple class of the form: @interface Whatever : NSObject { int somePrimitive; SomeObject* someObject; } @property (nonatomic) int somePrimitive; @property (nonatomic, retain) SomeObject* someObject; The class is more involved that this, but this illustrates the purpose. When I store instances of this class in a NSMutableDictionary: Whatever *whatever = [[Whatever alloc] init]; whatever.somePrimitive = 1; whatever.someObject = ...; [myDictionary setObject:whatever forKey:@"someKey"]; and then try to retrieve the object later: Whatever *result = [myDictionary valueForKey:@"someKey"]; then, result.someObject is ok to reference but, result.somePrimitive crashes. Does the NSDictionary not copy over the primitives of the object? Is the rule that the object stored in a dictionary should only contain objects?

  • Component not listening to MainApp's state change

    - by tag
    I don't know if this is too difficult or too easy. My custom component is trying to listen to the main application's state changes using StateChangeEvent.CURRENT_STATE_CHANGE private function init(){ addEventListener(StateChangeEvent.CURRENT_STATE_CHANGE, function():void{ Alert.show("parent state changed"); }); } but as expected, it's reporting its own state changes not the main application's. I have 2 options: figure a way to tell it that I really mean the main application's state change not its own or configure the main application to dispatch a specific custom event that the component would listen for Any idea how I could do the first? or do I need the second option in this case?

  • Object directing to a property when accessed as an iterable

    - by ThE_JacO
    I'm trying to figure out if there's an elegant and concise way to have a class accessing one of its own properties when "used" as a dictionary, basically redirecting all the methods that'd be implemented in an ordered dictionary to one of its properties. Currently I'm inheriting from IterableUserDict and explicitly setting its data to another property, and it seems to be working, but I know that UserDict is considered sort of old, and I'm concerned I might be overlooking something. What I have: class ConnectionInterface(IterableUserDict): def __init__(self, hostObject): self._hostObject= hostObject self.ports= odict.OrderedDict() self.inputPorts= odict.OrderedDict() self.outputPorts= odict.OrderedDict() self.data= self.ports This way I expect the object to behave and respond (and be used) the way I mean it to, except I want to get a freebie ordered dictionary behaviour on its property "ports" when it's iterated, items are gotten by key, something is looked up ala if this in myObject, and so on. Any advice welcome, the above seems to be working fine, but I have an odd itch that I might be missing something. Thanks in advance.
