  • Creating a JSONRepresentation of my NSDictionary messes up the order?

    - by Lewion
    Hi all, To pass data to my webservice, I create an NSDictionary with the objects and keys I need, and use JSONRepresentation to format it nicely so I can post it to my service. It all worked fine with the previous version where only 2 parameters were required. An array with listitems, and a UDID. No I also need to pass a version number because we need to provide more data for people with the application at this new version. Only problem is when I create my JSONRepresentation now, the order of things are all messed up. NSMutableDictionary *rowDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys:arrayDict,@"basketListV2",sharedData.udid,@"UDID",@"1.4",@"version",nil]; It prints out version first, then UDID and then basketListV2. Anyone know what I can do to maintain the order of my NSDict? I tried both NSDictionary and NSMutableDictionary (Probably doesn't have to do anything with it but for testing purposes I had to try it.) Thanks in advance. Lewion

  • Unset array element inside a foreach loop

    - by Richard Knop
    So here is my code: <?php $arr = array(array(2 => 5), array(3 => 4), array(7 => 10)); foreach ($arr as $v) { $k = key($v); if ($k > 5) { // unset this element from $arr array } } print_r($arr); // now I would like to get the array without array(7 => 10) member As you can see, I start with an array of sinwgle key = value arrays, I loop thorugh this array and get a key of the current element (which is a single item array). I need to unset elements of the array with key higher than 5, how could I do that? I might also need to remove elements with value less than 50 or any other condition. Basically I need to be able to get a key of the current array item which is itself an array with a single item.

  • undo or reverse argsort(), python

    - by Vincent
    Given an array 'a' I would like to sort the array by columns "a.sort(axis=0)" do some stuff to the array and then undo the sort. By that I don't mean re sort but basically reversing how each element was moved. I assume argsort() is what I need but it is not clear to me how to sort an array with the results of argsort() or more importantly apply the reverse/inverse of argsort() Here is a little more detail I have an array a, shape(a) = rXc I need to sort each column aargsort = a.argsort(axis=0) # May use this later aSort = a.sort(axis=0) now average each row aSortRM = asort.mean(axis=1) now replace each col in a row with the row mean. is there a better way than this aWithMeans = ones_like(a) for ind in range(r) # r = number of rows aWithMeans[ind]* aSortRM[ind] Now I need to undo the sort I did in the first step. ????

  • partially connected application using asp.net 3.5 (not mobile apps)

    - by Hari
    We had a requirement to build a ASP.NET 3.5 web application using web forms, WCF, ADO.NET and SQL Server. The users would connect via Internet. Recently we understood that it is possible that users would often remain disconnected and would have Internet access intermittently. I need to understand if we can create occasionally connected web application using asp.net 3.5 - what all technologies/features we need to use? Is MS Sync Framework the answer to the problem - is it a viable option to use with web application? Is windows application the right approach instead of web applications - where the business logic would be run at the client itself, using local SQL Express editions with data then been synced up with Enterprise SQL server at server end when connection is established using replication and/or MS Sync framework. In that case is there a need to use WCF? Does Silverlight applications help in this context -building paritally connected web apps? Really appreciate if you can give pointers to how to go about this task of creating .net partially connected apps (not mobile apps)?

  • Resize Array By Last and not by First in C#

    - by Leen15
    Hi all! I have an Array of Class elements, and by an int variable i need to resize this array to the last X elements. So for example i have an array with: Array[0] = Msg1 Array[1] = Msg2 Array[2] = Msg3 Array[3] = Msg4 Array[4] = Msg5 Array[5] = Msg6 Array[6] = Msg7 Array[7] = Msg8 Array[8] = Msg9 Array[9] = Msg10 and i need to have only the last 8 elements in the array. i cannot use the Array.Resize function because the result would be: Array[0] = Msg1 Array[1] = Msg2 Array[2] = Msg3 Array[3] = Msg4 Array[4] = Msg5 Array[5] = Msg6 Array[6] = Msg7 Array[7] = Msg8 and i need something like this: Array[0] = Msg3 Array[1] = Msg4 Array[2] = Msg5 Array[3] = Msg6 Array[4] = Msg7 Array[5] = Msg8 Array[6] = Msg9 Array[7] = Msg10 How can i do this? i hope my problem is clear. Thanks.

  • Paypal payments verify

    - by user2800899
    (sorry for my english). I have implemented Paypal sdk for android, it works fine! But maybe for my english I don´t understand what i have to do here: @Override protected void onActivityResult (int requestCode, int resultCode, Intent data) { if (resultCode == Activity.RESULT_OK) { PaymentConfirmation confirm = data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION); if (confirm != null) { try { Log.i("paymentExample", confirm.toJSONObject().toString(4)); // TODO: send 'confirm' to your server for verification. // see https://developer.paypal.com/webapps/developer/docs/integration/mobile/verify-mobile-payment/ // for more details. } catch (JSONException e) { Toast.makeText(this, "Ha ocurrido un error, inténtelo de nuevo en unos instantes", Toast.LENGTH_LONG).show(); IrActivityAnterior(); } } } I have read about it but I don´t know if I need to send a proof of payment to the person who has bought my app or if I only need to get this proof and save it. And the other question is how can I verify it? What steps I need to follow?? Thank you!!

  • UI to allow 700+ multiple choices

    - by Refracted Paladin
    In my desktop .NET application I have written(for internal use) where I need to allow my users to apply diagnosis's to a Member Plan. There are currently 700 in the system and growing. I need to allow them to add multiple diapnosis's at once. I currently am allowing this through a combo check list box. This works but is INSANELY unweildly for both myself and the users. What I am looking for is a how I could go about displaying these to the users. Ideally I would need to show two criteria for each each as well. Diagnosis Name and Diagnosis Code Ideas? How would you tackle this? I am using .Net 3.5sp1 and SQL 2005 for the backend. I don't care if the solution is WPF or Winforms.

  • Create numbers within an array that add up to a set amount

    - by RussellDias
    I'm fairly new to PHP - programming in general. So basically what I need to accomplish is, create an array of x amount of numbers (created randomly) who's value add up to n: Lets say, I have to create 4 numbers that add up to 30. I just need the first random dataset. The 4 and 30 here are variables which will be set by the user. Essentially something like x = amount of numbers; n = sum of all x's combined; create x random numbers which all add up to n; $row = array(5, 7, 10, 8) // these add up to 30 Also, no duplicates are allowed. I need the values with an array. I have been messing around with it sometime, however, my knowledge is fairly limited. Any help will be greatly appreciated. Cheers

  • Delphi Memory Management

    - by nomad311
    I haven't been able to find the answers to a couple of my Delphi memory management questions. I could test different scenarios (which I did to find out what breaks the FreeAndNil method), but its takes too long and its hard! But seriously, I would also like to know how you all (Delphi developers) handle these memory management issues. My Questions (Feel free to pose your own I'm sure the answers to them will help me too): Does FreeAndNil work for COM objects? My thoughts are I don't need it, but if all I need to do is set it to nil than why not stay consistent in my finally block and use FreeAndNil for everything? Whats the proper way to clean up static arrays (myArr : Array[0..5] of TObject). I can't FreeAndNil it, so is it good enough to just set it to nil (do I need to do that after I've FreeAnNil'd each object?)? Thanks Guys!

  • php string search - grabbing specific urls

    - by MEM
    Hello, I have this string that may contain some urls that I need to grab. For instance, if the user does: www.youtube ... or www.vimeo ... or http://www.youtube ... or HttP://WwW.viMeo I need to grab it (until he finds a space perhaps). and store it on a already created array. The need is to separate the vimeo links from the youtube ones and place each of those on the appropriate video object. I'm not sure if this is possible, I mean, if the URL coming from the browser could be used to be placed on a predefined video object. If it is, then this is the way to go (so I believe). If all this is feasible, can I have your help in order to build such a rule? Thanks in advance

  • Find first cell in a row that contains a number?

    - by Dexter
    I'm working in Excel with an exported table such as this: |-------------------------------------------------------------------------------| | | A | B | C | D | E | F | G | H | I | |---|-------------------|-----|-----|-----|-----|-----|-------|-----|-----------| | 1 | Domain | JAN | FEB | MAR | APR | MAY | Start | End | Change | |---|-------------------|-----|-----|-----|-----|-----|-------|-----|-----------| | 2 | www.mydomain1.com | | 1 | 4 | 3 | 1 | 1 | 1 | 0 | |---|-------------------|-----|-----|-----|-----|-----|-------|-----|-----------| | 3 | www.mydomain2.com | 2 | 4 | 12 | 18 | 23 | 2 | 23 | 21 | |---|-------------------|-----|-----|-----|-----|-----|-------|-----|-----------| | 4 | www.mydomain3.com | | | 14 | 12 | | 14 | xxx | NOT FOUND | |-------------------------------------------------------------------------------| I'm trying to compare the current state (last cell) to the original cell (first cell with a value). In column I, I have the formula =IF(G2 = "xxx", "NOT FOUND", IF(H2 = "xxx", "NOT FOUND", H2 - G2)) In column H, I have the formula =IF(F2 = "", "xxx", F2) In column G, I need to find the first cell with a number. If there isn't one in that range, I need G to be "xxx". I suppose I only need to check for the first cell in the range (B2 to F2) that contains a value, not just a number. I tried using an Index and Match combo, but I couldn't quite understand it.

  • MySQL comparisons between multiple rows

    - by Hurpe
    I have a MySQL table with the following columns: id(int), date (timestamp), starttime(varchar), endtime(varchar), ... I need to find time slots that are occupied by two or more rows. Here is an example table id| date |starttime|endtime | __|_____________________|_________|________| 1 | 2010-02-16 17:37:36 |14:35:00 |17:37:00| 2 | 2010-02-17 12:24:22 |12:13:00 |14:32:00| 3 | 2010-02-16 12:24:22 |15:00:00 |18:00:00| Rows 1 and 3 collide, and need to be corrected by the user. I need a query to identify such colliding rows - something that would give me the ID of all rows in the collision. When inserting data in the database I find collisions with this query: SELECT ID FROM LEDGER WHERE DATE(DATE) = DATE('$timestamp') AND ( STR_TO_DATE('$starttime','%H:%i:%s') BETWEEN STR_TO_DATE(STARTTIME,'%H:%i:%s') AND STR_TO_DATE(ENDTIME,'%H:%i:%s') OR STR_TO_DATE('$endtime','%H:%i:%s') BETWEEN STR_TO_DATE(STARTTIME,'%H:%i:%s') AND STR_TO_DATE(ENDTIME,'%H:%i:%s') ) AND FNAME = '$fname'"; Is there any way to accomplish this strictly using MySQL or do I have to use PHP to find the collisions?

  • C# thread safety for class instances

    - by Steveng
    I am learning C# and I am confused with the thread safety of the copies of the class instances as below: eg: classA objA; classA objB = objA; objA.field1 = value2; //do I need lock around modification of field1? //let say we pass the objB to another thread objB.field1 = value1 //do I need a lock for objB because of the modification of field1? I am confused because coming from the background of C++, the class in C# is the reference type. If both objA and objB refer to the same memory underlying, then I would need a lock to protect the simultaneous writing to the field1. Could someone confirm with this or am I missing something? Thanks.

  • How can i get the selected option name or id of a select element using jQuery

    - by bill
    Hi All, i have a "questionairre" that is made up of a series of select boxes. i need to use two properties in the options. For each selected option i need the value (which i know how to get and is working fine) but i also need to store an additional value which represents the id of the specific option in a DB. One solution would be to put the two values in the "value" property and parse it out.. but if there is some other property i can use that might be easier and clearer.. can i add a custom property?? like databaseId that could be accessed with jQuery? thanks for ANY suggestions.

Is there a framekwrok we need to build out, or what is the process functioanlly to define out to make these happen? Platform is being built on MySQL and Cake php.

  • convert string array to cell in MATLAB

    - by Maddy
    I need to output a cell to an excel file. Before this I need to convert a date column of integers to datestrings. I know how to do this, but I am not able to put this new string array back into the cell - mycell = { 'AIR' [780] [1] [734472] [0.01] ; ... 'ABC' [780] [1] [734472] [0.02]} I did this -- dates = datestr(cell2mat(mycell(:,4))) ; What I need as an answer is: {'AIR' [780] [1] '14-Dec-2010' [0.01] ; 'ABC' [780] [1] '23-Dec-2010' [0.03] ; } so that I can now send it to an excel file using xlswrite.m

  • Python: Picking an element without replacement

    - by wpeters
    I would like to slice random letters from a string. Given s="howdy" I would like to pick elements from 's' without replacement but keep the index number. For example >>> random.sample(s,len(s)) ['w', 'h', 'o', 'd', 'y'] is close to what I want, but I would actually prefer something like [('w',2), ('h',0), ('o',1), ('d',3), ('y',4)] with letter-index pairs. This is important because the same letter appears in 's' more than once. ie) "letter" where 't' appears twice but I need to distinguish the first 't' from the 'second'. Ideally I actually only need to pick letters as I need them but scrambling and calculating all the letters in a list (as shown above) is ok.

  • Use AJAX to check for a new message

    - by Luke
    Quite simply, I need to alert the end user when they have a new private message. From a combination of research and other opinion, I realise I need to use AJAX for this. The mysql query would be SELECT id FROM tbl_messages WHERE to_viewed = 1 So when someone sends a message, I want an alert to popup on the screen to inform the user without a page reload. I have absolutely no idea what I am doing, but know what I want. Really need help with this, AJAX is definitely something I want to improve as it opens up greater possibilities! Thanks

  • Writing different structs to a file in C++? [on hold]

    - by user58053
    I need a way to write structures of three different kinds to a binary file, which later has to be searched. (As in, for example, struct A has two fields, an int and a char; struct B has int and a long; I need to output all structures whose int equals the one given from keyboard). I understand how to write structs of the same kind to a file and how to search them, but here I am just lost, best thing I came up with is declaring a struct containing all possibly needed fields and leaving the ones I don't need empty, but it really feels wrong, there HAS to be a better way to do that. I've read about binary files and could not find anything relevant, most examples and tutorials deal with writing one data type. Could anyone point me in the right direction? EDIT: I am looking for what @Jerry_coffin called database mode, and will probably use one of the existing database systems for that, best way to go, probably. Thank you everybody for the suggestions

  • why include() don't allow to work setcookie?

    - by Syom
    i need to set cookies in my page, but it returns Warning: Cannot modify header information - headers already sent by (output started at /home1/bsam/public_html/24kadr/index.php:1) in /home1/bsam/public_html/24kadr/basic_login.php on line 35 on line 1 i have include 'basic_login.php'; but even if i remoove include, ir returns the same warning on session_start, or mysql_connect. so i think these all functions use header when calling, but what can i do? at least i need to connect to database, and just after it i need to use setcookie(). so what can i do? thanks

I do not want to use Lame because it is too big while no programmer can answer a simple question on it (share simple but easily downloadable and readable project containing only needed 2 simple functions... So I'm tired of searching for help with it.. I need something fresh powerful but more readable than this lib I found (mp3stego) ) "I don't want LAME because I am a fighter with its monopoly" Haha..

This list contains the datestamp and serial number. I need to pick the correct serial number. Objecthistory is the List object and I need to get the latest timestamp within this ObjectHistory. I need to pick the latest timestamp from this Arraylist in Java 6. How should I be doing this? Should I do convert these values into calendar-time? I am in panic mode as this has to be done directly in production.
