  • Send a String[] ArrayList over Socket connection

    - by Duncan Palmer
    So i'm trying to send a String[] Array/List over an open socket connection. I currently have this code: Sending: public void sendData() { try { OutputStream socketStream = socket.getOutputStream(); ObjectOutputStream objectOutput = new ObjectOutputStream(socketStream); objectOutput.writeObject(new String[] {"Test", "Test2", "Test3"}); objectOutput.close(); socketStream.close(); } catch (Exception e) { System.out.println(e.toString()); } } Recieving: public Object readData() { try { InputStream socketStream = socket.getInputStream(); ObjectInputStream objectInput = new ObjectInputStream(new GZIPInputStream(socketStream)); Object a = objectInput.readObject(); return a; } catch(Exception e) { return null; } } After I have recieved the String array/list on the other end I want to be able to iterate through it like I would do normally so I can get the values. My current code doesn't seem to works as it returns null as the value. is this possible?

  • Get the names of IDs from different table

    - by user896692
    I have an array with a lot of data from a database. In the array, there are two fields called teameinsid and teamzweiid. The query is a very simple one : $spiel = mysql_query("select teameinsid, teamzweiid from begegnung", $connection) or die("Keine passende Begegnung"); What I need is to search in the database for the names of these IDs. The names are in a different table. What I have now is the following: while($tmp = mysql_fetch_array($spiel)){ $teins = $tmp['teameinsid']; $tzwei = $tmp['teamzweiid']; } So I know the two IDs, but I don't know where to save the names. If I try: $name = mysql_query("select name from team where teameinsid = $teins", $con) it gets overwritten every time. How can I manage this?

  • UITableView with multiple selections

    - by NewDev
    I have a UITableView with multiple selections enabled. If I select items and scroll the list back and forth they are remembered and shown and selected (blue background). Using the didDeselectRowAtIndexPath and didSelectRowAtIndexPath I am able to keep my own array of selected items. That part works well. However, if I then use the sectionForSectionIndexTitle and jump to a letter, the selection appears to be forgotten - even indexPathForSelectedRows appears to have been reset and is now empty. My own array remembers that an item is selected and I can set the cell.selected in the cellForRowAtIndexPath but the instant I move the list it is forgotten again. Any ideas? Is this a bug, or how do you retain the selection list when jumping to a letter?

  • Is there a way to delete a form element without using jQuery .remove()?

    - by Tommy
    Using .remove() so that the select all check box is not submitted to the server. However, it is visible to the user as the select all checkbox is "physically" removed from the web page, upon submit. Instead, I would like removing the select all check box to appear seamless but NOT on the server side. i.e. - I would like to keep the input on the page but remove the element in the form array before it is sent. Can I manipulate the element[] array of the form before it is sent to the server and delete it there? Thank you.

  • What's wrong with this Perl 'grep' syntax?

    - by wes
    I've got a data structure that is a hash that contains an array of hashes. I'd like to reach in there and pull out the first hash that matches a value I'm looking for. I tried this: my $result = shift grep {$_->{name} eq 'foo'} @{$hash_ref->{list}}; But that gives me this error: Type of arg 1 to shift must be array (not grep iterator). I've re-read the perldoc for grep and I think what I'm doing makes sense. grep returns a list, right? Is it in the wrong context? I'll use a temporary variable for now, but I'd like to figure out why this doesn't work.

  • Substitute all matches with values in Ruby regular expression

    - by Lewisham
    Hi all, I'm having a problem with getting a Ruby string substitution going. I'm writing a preprocessor for a limited language that I'm using, that doesn't natively support arrays, so I'm hacking in my own. I have a line: x[0] = x[1] & x[1] = x[2] I want to replace each instance with a reformatted version: x__0 = x__1 & x__1 = x__2 The line may include square brackets elsewhere. I've got a regex that will match the array use: array_usage = /(\w+)\[(\d+)\]/ but I can't figure out the Ruby construct to replace each instance one by one. I can't use .gsub() because that will match every instance on the line, and replace every array declaration with whatever the first one was. .scan() complains that the string is being modified if you try and use scan with a .sub()! inside a block. Any ideas would be appreciated!

  • i have a arraylist where i am verifying particular object is existing or not but even it exists it always returns false

    - by Raghavender Reddy
    hi i have class called userdata which returns the Userarraylist which is of type User. when ever i try to use contains method to check particular property is existing or not it always returns false why? Actually i want the array list to be generic which should return the objects that are set in array list. String className = data.getUserData().get(0).getClass().getSimpleName(); if(className.equalsIgnoreCase("User")) { ArrayList<User> userdata=new ArrayList(); userdata = data.getUserData(); System.out.println(data.getUserData().contains(u.getUserId())); if(userdata.contains(u.getUserName())) { System.out.println(userdata.get(0).getEmailId()); } }

  • How do I get a Type[] with arguments from a MethodCallExpression?

    - by Tomas Lycken
    I'm reflecting over a class (in a unit test of said class) to make sure its members have all the required attributes. To do so, I've constructed a couple of helpers, that take an Expression as an argument. I do some checks for it, and take slightly different actions depending on what type of Expression it is, but it's basically the same. Now, my problem is that I have several methods with the same name (but different signatures), and the following code throws an AmbiguousMatchException: // TOnType is a type argument for the type where the method is declared // mce is the MethodCallExpression var m = typeof(TOnType).GetMethod(mce.Method.Name); Now, if I could add an array of Type[] with the types of the arguments to this method as a second parameter to .GetMethod(), the problem would be solved. But how do I find this Type[] array that I need? I have cast the Expression<Func<...>> to an Expression, and then to a MethodCallExpression, and in this method the contents of <...> is not known.

  • Checking for multiple images loaded

    - by Stanni
    Hi, I'm using the canvas feature of html5. I've got some images to draw on the canvas and I need to check that they have all loaded before I can use them. I have declared them inside an array, I need a way of checking if they have all loaded at the same time but I am not sure how to do this. Here is my code: var color = new Array(); color[0] = new Image(); color[0].src = "green.png"; color[1] = new Image(); color[1].src = "blue.png"; Currently to check if the images have loaded, I would have to do it one by one like so: color[0].onload = function(){ //code here } color[1].onload = function(){ //code here } If I had a lot more images, Which I will later in in development, This would be a really inefficient way of checking them all. How would I check them all at the same time?

  • PHP 1-liner each() with mysql_fetch_assoc()

    - by MVC You Know Me
    Hey All. Trying to create a 1-liner to loop through a mysql result set. Example: $sql = "SELECT uid, role FROM usr WHERE uid = '$this-uid'"; $r = db::q($sql); if($r-rows()) { $q = mysql_fetch_assoc($r-result); while(list($k, $v) = each($q)) { // would like to omit line above and consolidate here $_SESSION['usr'][$k] = $this->$k = $v; } } problem is that consolidating while loop like so: while(list($k, $v) = each(mysql_fetch_assoc($r-result)) returns an error a la each() not getting object or array, even though of course it is. I think the problem is a casting issue, but it does not seem you can do: each( (array) mysql_fetch_assoc($r-result)) Any ideas? I like to code as tersely as possible, and having "$q = mysql_fetch_assoc($r-result)" everywhere will annoy me, does already. Keep posted... Thanks!

  • Incrementing through mysql PHP

    - by Rawdon
    I am looking at try to increment and decrement by three records through a table and present those records. Say if the id '4' is currently active. I want the to be display the ID's and category of 3.2.1 and 5.6.7 from an increment and decrement So far I have: $stmt = $db->query("SELECT id, category FROM test"); $stmt->execute(); while ($results = $stmt->fetch(PDO::FETCH_ASSOC)) { $current = $results['id']; $category = $results['category']; $next = array(array('slide_no' => $current, 'category' => $category)); } print_r($next); Now with this, I am getting back every row in the table. I'm now getting confused on how I could increment and decrement the records by 3 and make sure that the category will also increment correctly. Thank you very much.

  • How do I change the background image of my app?

    - by user356387
    Hello I have looked around and found some code which so called chooses an image from an array of image objects, but cant find an explanation. I would like to make my app have a background image and the user can select next and previous buttons to scroll through some full screen images, setting them as the background image as they scroll. I know how to do this in java, but cant seem to do it for this app. How or what code is linked to a next button to grab the next image in the array and reverse for the back button? Then that needs to be displayed obviously. I have used a layered architecture with a MVC style approach but cant seem to put it together with Objective-C. Would the buttons call the appropriate methods of the so called delegates, which the delegates handle fetching and returning the Images? Would the buttons use the returned images and actually handle the redrawing? I would really appreciate the help. Regards Jarryd

  • PHP __call vs method_exists

    - by neo
    The Project I'm working on contains something like a wrapper for call_user_func(_array) which does some checks before execution. One of those checks is method_exists (In Case the supplied first argument is an instance of a class and the second is a method name) The other is_callable. The function will throw an exception if one of those checks fails. My Code contains an array with function names (setFoo, setBar, etc.) and the php magic function for overloading (__call) which handles setting, replacing and deletion of certain variables (better certain array elements). The Problem: method_exists will return false if the function is not defined. Do I have any chance to get a true if the __call function does proper handling of the request?

  • jquery integrate form parameter in one object

    - by jesse
    There are many forms in my page. I want to merge them in one object and submit them in one object. But I find serializeArray() or serialize() do not match my request, the serializeArray function will generate a array object and serialize is used by get model, it is not an object. is there a jquery or local function can merge them in one object. I have one solution but it is not perfect, loop the array object generated by serializeArray, use $.extend to merge them in one object. is there a better method? kindly help, thanks.

  • jquery: find common elements in 2 sets of divs

    - by tsiger
    For a markup like this: <div id="set1"> <div id="100">a div</div> <div id="101">another div</div> <div id="102">another div 2</div> <div id="120">same div</div> </div> <div id="set2"> <div id="105">a different div> <div id="101">another div</div> <div id="110">more divs</div> <div id="120">same div</div> </div> As you can see both #set1 and #set2 contain 2 divs with the same id (101, 120). Is it possible somehow with jQuery to find the common elements and add a class to the divs in #set1 that have the same id with divs in #set2? In other words after the script run the above code would look like this: <div id="set1"> <div id="100">a div</div> <div id="101" class="added">another div</div> <div id="102">another div 2</div> <div id="120" class="added">same div</div> </div> <div id="set2"> <div id="105">a different div> <div id="101">another div</div> <div id="110">more divs</div> <div id="120">same div</div> </div> EDIT playing around with it i did something but i am not sure it can go anywhere. I created an array with the ids in both sets and in Firebug i can see an array with the values var arrEl = []; $('#set1 div, #set2 div').each( function(index) { var id = $(this).attr('id'); arrEl.push(id); //maybe somehow check the array for the values that appear twice, and add the class to the //matching divs? });

  • How to choose programaticaly the column to be queried by Linq using PropertyInfo???

    - by Richard77
    Hello, I would like to control how linq querries my database programaticaly. For instance, I'd like to query the column X, column Y, or column Z, depending on some conditions. First of all, I've created an array of all the properties inside my class called myPropertyInfo. Type MyType = (typeOf(MyClass)); PropertyInfo[] myPropertyInfo = myType.GetProperties( BindingFlags.Public|BindingFlags.Instance); The myPropertyInfo array allows me to access each property details (Name, propertyType, etc) through the index*[i]* Now, how can I use the above information to control how linq queries my DB? Here's a sample of a querry I'd like to exploit. var myVar = from tp in db.MyClass select tp.{expression}; Expression using myPropertyInfo[i] to choose which property(column) to query. I'm not sure if that's the way of doing it, but if there's another way to do so, I'll be glad to learn. Thanks for helping.

  • strategy to allocate/free lots of small objects

    - by aaa
    hello I am toying with certain caching algorithm, which is challenging somewhat. Basically, it needs to allocate lots of small objects (double arrays, < 256 elements), with objects accessible through mapped value, map[key] = array. time to initialized array may be quite large, generally more than 10 thousand cpu cycles. By lots I mean around gigabyte in total. objects may need to be popped/pushed as needed, generally in random places, one object at a time. lifetime of an object is generally long, minutes or more, however, object may be subject to allocation/deallocation several times during duration of program. What would be good strategy to avoid memory fragmentation, while still maintaining reasonable allocate deallocate speed? I am using C++, so I can use new and malloc. Thanks. I know there a similar questions on website, http://stackoverflow.com/questions/2156745/efficiently-allocating-many-short-lived-small-objects, are somewhat different, thread safety is not immediate issue for me.

  • Strange behaviour of mb_detect_order() in PHP

    - by termopro
    I would like to detect encoding of some text (using PHP). For that purpose i use mb_detect_encoding() function. The problem is that the function returns different results if i change the order of possible encodings with mb_detect_order() function. Consider the following example $html = <<< STR ????????????????????????????????????????????????????????????????????????????????????????????????????????? STR; mb_detect_order(array('UTF-8','EUC-JP', 'SJIS', 'eucJP-win', 'SJIS-win', 'JIS', 'ISO-2022-JP','ISO-8859-1','ISO-8859-2')); $originalEncoding = mb_detect_encoding($str); die($originalEncoding); // $originalEncoding = 'UTF-8' However if you change the order of encodings in mb_detect_order() the results will be different: mb_detect_order(array('EUC-JP','UTF-8', 'SJIS', 'eucJP-win', 'SJIS-win', 'JIS', 'ISO-2022-JP','ISO-8859-1','ISO-8859-2')); die($originalEncoding); // $originalEncoding = 'EUC-JP' So my questions are: Why is that happening ? Is there a way in PHP to correctly and unambiguously detect encoding of text ?

  • Serialize object from within

How can I serialize object from within the class to do that? class testClass { private $prop = 777; public function save() { $serializedObject = serialize(self); DB::insert('objects', array('id', 'object')) ->values(array(1, $serializedObject)) ->execute(); } } serialize(self) obviously doesn't work.
