  • iphone - keeping the last frame of a frame animation visible

    - by Mike
    I have this code UIImageView *sequence = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"balao_surge0.png"]]; NSMutableArray *array = [[NSMutableArray alloc] init] ; for (int i=0; i<30; i++) { UIImage *oneImage = [UIImage imageNamed:[NSString stringWithFormat:@"balao_surge%d.png",i]]; [array addObject:oneImage]; } sequence.animationImages = array; sequence.animationDuration = 2.0; sequence.animationRepeatCount = 1; [umaVista addSubview:sequence]; [sequence release]; sequence.startAnimating; The animation plays fine, but after the last frame is shown, it vanishes. I would like to make it stay visible, that is, make the animation stop on the last frame. Is there any way to do that? thanks for any help.

  • Regex: replace inner string

    - by AllenG
    I'm working with X12 EDI Files (Specifialy 835s for those of you in Health Care), and I have a particular vendor who's using a non-HIPAA compliant version (3090, I think). The problem is that in a particular segment (PLB- again, for those who care) they're sending a code which is no longer supported by the HIPAA Standard. I need to locate the specific code, and update it with a corrected code. I think a Regex would be best for this, but I'm still very new to Regex, and I'm not sure where to begin. My current methodology is to turn the file into an array of strings, find the array that starts with "PLB", break that into an array of strings, find the code, and change it. As you can guess, that's very verbose code for something which should be (I'd think) fairly simple. Here's a sample of what I'm looking for: ~PLB|1902841224|20100228|49KC15X078001104|.08~ And here's what I want to change it to: ~PLB|1902841224|20100228|CSKC15X078001104|.08~ Any suggestions?

  • [cocoa] NSSearchField not working as expected

    - by Vegar
    Hi, I'm trying to follow Marcus Zarra in his book 'Core Data'. In the book, he makes a small sample application, but it doesn't give much help when things don't work out... He starts out by visually designing three entities, and then adding array controllers for each entity to the main nib. Second, he adds a tableview and some other visual components to show data from the array controllers. So far, I have managed to follow, but now he adds a search field to the gui, and binds it to the same array controller as one of the tableviews. Expected behavior would be for the tableview to get filtered when typing in the search field, but nothing happens. How do I find out what's wrong? The relevant parts from the nib is as follow: NSArrayController Recipes - Mode = Entity - Enitity Name = Recipe TableView w/TableColumn - Value Bind To Recipes -- Controller Key = arrangedObjects -- Model Key Path = name Search Field - Predicate Bind To Recipes -- Controller Key = filterPredicate -- Model Key Path = name -- Display name = predicate -- Predicate Format = keyPath contains $value There are no relevant messages in the console. regards, -Vegar

    Hello, I have an object in Javascript that looks like this function MyObject(){ this.name=""; this.id=0; this..... } I then stringify an array of those objects and send it to an ASP.Net web service. Now what I want to do is do some processing on the JSON objects given to the webservice and return a JSON array of the same type of objects(same field names and such) How would I do this easily? I am using Netwonsoft.Json. Is there some way to turn a JSON string into a List or Array of an object?

  • Pass-by-Reference Error

    - by TK
    I have a hook system setup... which is working on localhost... I put it live and get an error saying "Warning: Call-time pass-by-reference has been deprecated". Now, apparently the work around is to remove all "&" from your function calls, ie foo(&$me) to foo($me) and then in foo's function definition do "function foo(&$me)". However, I can not do this... because my hooks accept an array as arguments, I need a work around for this. Like I can use "run_hooks ( 'hook-name', $me );" or "run_hooks ( 'hook-name', array ( $me, $another_var, etc... ) )"; So this means I can not use "function run_hooks ( $hook_name, &$arguments )" because I'll get an error in php saying it can not pass "array()" as reference... Any ideas an a work around? Thanks.

  • Heap Dump Root Classes

    - by Adnan Memon
    We have production system going into infinite loop of full gc and memory drops form 8 gigs to like 1 MB in just 2 minutes. After taking heap dump it tells me there an is an array of java.lang.Object ([Ljava.lang.Object) with millions of java.lang.String objects having same String taking 99% of heap. But it doesn't tell me which class is referencing to this array so that I can fix it in the code. I took the heap dump using jmap tool on JDK 6 and used JProfiler, NetBeans, SAP Memory Analyzer and IBM Memory Analyzer but none of those tell me what is causing this huge array of objects?? ... like what class is referencing to it or contains it. Do I have to take a different dump with different config in order to get that info? ... Or anything else that can help me find out the culprit class causing this ... it will help a lot.

  • CakePHP: find neighbors, order on 'name' or 'order'

    - by Brelsnok
    Hi, I have a list of ordered items, ordered according to the int field order. I'm creating a gallery in CakePHP 1.2 that has a prev and next button and those should link to the previous and next item according to their ordering, not according to their id. In order to get this result I've included the 'order' parameter to the find function, and populated it with 'Item.order'=>'DESC'. Still the result is an id ordered list. My question is: what do I do wrong? My controller: $this->Item->id = 16; $neighbours = $this->Item->find('neighbors', array('order'=>array('Item.order'=>'DESC'), 'fields'=>array('id','name')));

  • How to use NSPredicate for Key-Path values

    - by randombits
    Using an NSPredicate for an array is rather straight forward using filteredArrayUsingPredicate:. How is this done for key-path values? Meaning, I have an array of objects (in this case, the objects are of the same type). The objects each have an instance variable called name. As per the documentation, it says to do the following: NSPredicate *predicate = [NSPredicate predicateWithFormat: @"ANY employees.firstName like 'Matthew'"]; Is that -also- used in filteredArrayUsingPredicate? What if I have an array of People objects? does that mean I would use: NSArray *allPeopleObjects; // pre-populated NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ANY people.name like 'Foo'"]; NSArray *matching = [allPeopleObjects filteredArrayUsingPredicate:predicate]; Documentation is a bit lacking in that department.

  • yii combining addColumnCondition in CDbCriteria

    - by keeg
    I have a couple of dropdown filters in my GridView, in the search part of my model I have: if ($this->agent_primary != "") { $criteria->addColumnCondition(array('agent_type_id'=>1, 'agent.agent_id'=>$this->agent_primary)); } if ($this->agent_voice != "") { $criteria->addColumnCondition(array('agent_type_id'=>2, 'agent.agent_id'=>$this->agent_voice)); } if ($this->agent_commercial != "") { $criteria->addColumnCondition(array('agent_type_id'=>3, 'agent.agent_id'=>$this->agent_commercial)); } I need to somehow combine this so if someone selects two of the three dropdowns (or all three) they get the correct results, currently the sql has there WHERE in separate brackets for each addColumnCondition: WHERE (condition1a = a AND condition1b = b) AND (condition2a = a AND condition2b = b) instead of WHERE (condition1a = a AND condition1b = b) OR (condition2a = a AND condition2b = b)

  • What's an efficient way of calculating the nearest point?

    - by Griffo
    I have objects with location data stored in Core Data, I would like to be able to fetch and display just the nearest point to the current location. I'm aware there are formulas which will calculate the distance from current lat/long to a stored lat/long, but I'm curious about the best way to perform this for a set of 1000+ points stored in Core Data. I know I could just return the points from Core Data to an array and then loop through that looking for the min value for distance between the points but I'd imagine there's a more efficient method, possibly leveraging Core Data in some way. Any insight would be appreciated. EDIT: I don't know how I missed this on my initial search but this SO question suggests just iterating through an array of Core Data objects but limiting the array size with a bounding box based on the current location. Is this the best I can do?

  • how to handle duplicates in AVL tree

    - by Ahmed Kotb
    I want to make my avl tree support adding duplicates but there is a problem with the default behavior of the binary search tree with duplicates that the rotation could make nodes with equal key be on the left and the right of the parent for example adding A,A,A will cause the tree to do a rotation to be something like that A / \ A A so getting all the entries with that key will be a problem...and searching in both direction is not something good the solution that i have thought of is making each node stores an array of duplicates so when adding a new item that already exists will be just adding a new item to the array , removing item with key will delete the whole node while the find all items with key will return that array. are there are any other methods to handle duplicates ?

  • I've Heard Global Variables Are Bad, What Alternative Solution Should I Use?

    - by Jay
    I've read all over the place that global variables are bad and alternatives should be used. In Javascript specifically, what solution should I choose. I'm thinking of a function, that when fed two arguments (function globalVariables(Variable,Value)) looks if Variable exists in a local array and if it does set it's value to Value, else, Variable and Value are appended. If the function is called without arguments (function globalVariables()) it returns the array. Perhaps if the function is fired with just one argument (function globalVariables(Variable)) it returns the value of Variable in the array. What do you think? I'd like to hear your alternative solutions and arguments for using global variables.

  • PHP extract GPS EXIF data

    - by Kami
    I would like to extract the GPS EXIF tag from pictures using php. I'm using the exif_read_data() that returns a array of all tags + data : GPS.GPSLatitudeRef: N GPS.GPSLatitude:Array ( [0] => 46/1 [1] => 5403/100 [2] => 0/1 ) GPS.GPSLongitudeRef: E GPS.GPSLongitude:Array ( [0] => 7/1 [1] => 880/100 [2] => 0/1 ) GPS.GPSAltitudeRef: GPS.GPSAltitude: 634/1 I don't know how to interpret 46/1 5403/100 and 0/1 ? 46 might be 46° but what about the rest especially 0/1 ? angle/1 5403/100 0/1 What is this structure about ? How to convert them to "standard" ones (like 46°56'48?N 7°26'39?E from wikipedia) ? I would like to pass thoses coordinates to the google maps api to display the pictures positions on a map !

  • Interpolating 2d data that is piecewise constant on faces

    - by celil
    I have an irregular mesh which is described by two variables - a faces array that stores the indices of the vertices that constitute each face, and a verts array that stores the coordinates of each vertex. I also have a function that is assumed to be piecewise constant over each face, and it is stored in the form of an array of values per face. I am looking for a way to construct a function f from this data. Something along the following lines: faces = [[0,1,2], [1,2,3], [2,3,4] ...] verts = [[0,0], [0,1], [1,0], [1,1],....] vals = [0.0, 1.0, 0.5, 3.0,....] f = interpolate(faces, verts, vals) f(0.2, 0.2) = 0.0 # point inside face [0,1,2] f(0.6, 0.6) = 1.0 # point inside face [1,2,3] The manual way of evaluating f(x,y) would be to find the corresponding face that the point x,y lies in, and return the value that is stored in that face. Is there a function that already implements this in scipy (or in matlab)?

  • Decrypting “long” message encrypted with RSA java

    - by Denis
    Hi this is the same question, that was asked two years ago: Java/JCE: Decrypting “long” message encrypted with RSA I had a large byte array and rsa keypair, initiated by value 1024. Using rsa encryption and the specified size of the key is strong requirement, I can't change it. So I can't use symmetric encryption with asymetric encryption symmetric key. I can't use any other keys. I had a byte array and need ciphered byte array to be returned. I wonder if there is any ready tool, that can manage with this problem? Sorry for such an amateurish question, but I really need a help.

  • Copy hashtable to another hashtable using c++

    - by zengr
    I am starting with c++ and need to know, what should be the approach to copy one hashtable to another hashtable in C++? We can easily do this in java using: HashMap copyOfOriginal=new HashMap(original); But what about C++? How should I go about it? UPDATE Well, I am doing it at a very basic level,perhaps the java example was a wrong one to give. This is what I am trying to implement using C++: I have this hash array and each element of the array point to the head of a linked list. Which has it's individual nodes (data and next pointer). And now, I need to copy the complete hash array and the linked list each node is pointing to.

  • PHP - Rotate a HEX color value (eg swap all colors with "next" hex)

    - by Joe
    I have a set of hex values in an array in PHP. On my page, I have a slider which the user can "slide" to return a value between 1-100. I want to then, based on this slider value, swap all the colors in the array based on the colors "next" color based on the position in the array. An example of the same sort of thing would be like in photshop where you can rotate the hue of a layer. I want to do the same thing, in PHP, for a hex value. Any clues?

  • byte[] operations in Java

    - by kape123
    Let's say I have array of bytes: byte[] arr = new byte[] { 0, 1, 2, 3, 4 }; Does platform has functions that I can use to play with this array - for example, how to invert it (get 4,3,2,1,0)? Or, how to invert part of it (2,1,0,3,4)? Get part of array (0,1,2,3)? I know I can manually write functions but I am curious if I'm missing useful util functions in platform that I should know about (and couldn't find any useful guide using google). Thanks!

  • address representation in ada

    - by maddy
    Hi all, I have pasted a code below which is in ada language.I need some clarification on some implementations. C : character; Char : character; type Myarr_Type is array (character range 'A'..'K') of character; Myarr : Myarr_Type := ('A','B','C','D','E','F','G','H','I','J','K'); Next_Address := Myarr'address Last_Address := Next_Address + Storage_Offset'(40); my_func(int P1,int P2) { return P2 + Storage_Offset'(4); } Last_Address := Next_Address + Storage_Offset'(4); Now my doubt is 1)what does P2 + Storage_Offset'(4) actually mean.Does that mean that its returning the address of the next element in the array which is 'B'.Storage_Offset'(4) in ada --does this mean 4 bits or 4 bytes of memory. 2) If i assume that Last_Address points to last element of the array which is 'K',how does the arithmentic Storage_Offset'(40) satisfies the actual implementation? Please get back to me if u need any more clarifications. Thanks Maddy

  • java: can I convert strings with String.getBytes() without the BOM?

    Suppose I have this code: String encoding = "UTF-16"; String text = "[Hello StackOverflow]"; byte[] message= text.getBytes(encoding); If I display the byte array in message, the result is: 0000 FE FF 00 5B 00 48 00 65 00 6C 00 6C 00 6F 00 20 ...[.H.e.l.l.o. 0010 00 53 00 74 00 61 00 63 00 6B 00 4F 00 76 00 65 .S.t.a.c.k.O.v.e 0020 00 72 00 66 00 6C 00 6F 00 77 00 5D .r.f.l.o.w.] As you can see, there's a BOM in the beginning. How can I: generate a UTF-16 byte array that lacks a BOM ? convert from a byte array that contains UTF=16 chars but lacks a BOM, back to a string?

  • Multidimensional arrays in VB.NET 2010

    - by matt_t
    Is there any way to create a multidinensional array that contains arrays of different lengths (similar to nesting arrays of different lengths in python). Because if I were to declare a variable Dim accounts(2,2) As Integer all 1D arrays at each dimension have the same length. Is there any way to create an array so that this is not the case? e.g The above code would create an array like this: [[0,0],[0,0]] but would it be possible to create this: [[0,0],[0,0,0]] Apologies for the poor explanation but I cannot think of any better ways to explain.
