• Recommendations for easy jQuery Autocomplete using AJAX that will set form value based on selected t

  - by Ben Dauphinee

  I am looking for suggestions on the easiest to set up and use AJAX Autocomplete plugin that will use JSON key/value pairs. I want a plugin that supports setting the form value to the key of the name selected. I have been working with jQuery UI Autocomplete, but it is a total pain in the rear to get this working. Does anyone know of anything that actually supports this out of the box, or have a thread or page where this is already detailed?

• default value support for Entity Framework object construction to avoid having to set this column pa

  - by Greg

  Hi, In entity framework is there a way to have a default value for a column such that Linq to Entity won't require this parameter when constructing a new object? For example I've marked on column in the EF designer with a default value (I typed in "All" as it was a string). But if I try to construct a new record and not specify this parameter I still get a FOREIGN KEY constraint exception. The INSERT statement conflicted with the FOREIGN KEY constraint "FK_FunctionalityTypeInterfaceRelationship"

• Strange results - I obtain same value for all keys

  - by Pietro Luciani

  I have a problem with mapreduce. Giving as input a list of song ("Songname"#"UserID"#"boolean") i must have as result a song list in which is specified how many time different useres listen them... so a output ("Songname","timelistening"). I used hashtable to allow only one couple . With short files it works well but when I put as input a list about 1000000 of records it returns me the same value (20) for all records. This is my mapper: public static class CanzoniMapper extends Mapper<Object, Text, Text, IntWritable>{ private IntWritable userID = new IntWritable(0); private Text song = new Text(); public void map(Object key, Text value, Context context) throws IOException, InterruptedException { /*StringTokenizer itr = new StringTokenizer(value.toString()); while (itr.hasMoreTokens()) { word.set(itr.nextToken()); context.write(word, one); }*/ String[] caratteri = value.toString().split("#"); if(caratteri[2].equals("1")){ song.set(caratteri[0]); userID.set(Integer.parseInt(caratteri[1])); context.write(song,userID); } } } This is my reducer: public static class CanzoniReducer extends Reducer<Text,IntWritable,Text,IntWritable> { private IntWritable result = new IntWritable(); public void reduce(Text key, Iterable<IntWritable> values, Context context) throws IOException, InterruptedException { Hashtable<IntWritable,Text> doppioni = new Hashtable<IntWritable,Text>(); for (IntWritable val : values) { doppioni.put(val,key); } result.set(doppioni.size()); //doppioni.clear(); context.write(key,result); } } and main: Configuration conf = new Configuration(); Job job = new Job(conf, "word count"); job.setJarByClass(Canzoni.class); job.setMapperClass(CanzoniMapper.class); //job.setCombinerClass(CanzoniReducer.class); //job.setNumReduceTasks(2); job.setReducerClass(CanzoniReducer.class); job.setOutputKeyClass(Text.class); job.setOutputValueClass(IntWritable.class); FileInputFormat.addInputPath(job, new Path(args[0])); FileOutputFormat.setOutputPath(job, new Path(args[1])); System.exit(job.waitForCompletion(true) ? 0 : 1); Any idea???

• jQuery: modify hidden form field value before submit

  - by Jason Miesionczek

  I have the following code in a partial view (using Spark): <span id="selectCount">0</span> video(s) selected. <for each="var video in Model"> <div style="padding: 3px; margin:2px" class="video_choice" id="${video.YouTubeID}"> <span id="video_name">${video.Name}</span><br/> <for each="var thumb in video.Thumbnails"> <img src="${thumb}" /> </for> </div> </for> # using(Html.BeginForm("YouTubeVideos","Profile", FormMethod.Post, new { id = "youTubeForm" })) # { <input type="hidden" id="video_names" name="video_names" /> <input type="submit" value="add selected"/> # } <ScriptBlock> $(".video_choice").click(function() { $(this).toggleClass('selected'); var count = $(".selected").length; $("#selectCount").html(count); }); var options = { target: '#videos', beforeSubmit: function(arr, form, opts) { var names = []; $(".selected").each(function() { names[names.length] = $(this).attr('id'); }); var namestring = names.join(","); $("#video_names").attr('value',namestring); //alert(namestring); //arr["video_names"] = namestring; //alert($.param(arr)); //alert($("#video_names").attr('value')); return true; } }; $("#youTubeForm").ajaxForm(options); </ScriptBlock> Essentially i display a series of divs that contain information pulled from the YouTube API. I use jQuery to allow the the user to select which videos they would like to add to their profile. When i submit the form i would like to populate the hidden field with a comma separated list of video ids. Everything works except that when i try to set the value of the field, in the controller on post, the field comes back empty. I am using the jQuery ajax form plugin. What am i doing wrong that is not allowing the value i set in the field to be sent to the server?

  Hi, private void Form1_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.W) player1.moveUp(); if (e.KeyCode == Keys.NumPad8) player2.moveUp(); } In the above code the moveUp methods basically just increment a value. I want it so both keys can be pressed (or held down)at the same time and both events will trigger. Thanks, Nevik

• simulate backspace key with java.awt.Robot

  - by Tyler

  There seems to be an issue simulating the backspace key with java.awt.Robot. This thread seems to confirm this but it does not propose a solution. This works: Robot rob = new Robot(); rob.keyPress(KeyEvent.VK_A); rob.keyRelease(KeyEvent.VK_A); This doesn't: Robot rob = new Robot(); rob.keyPress(KeyEvent.VK_BACK_SPACE); rob.keyRelease(KeyEvent.VK_BACK_SPACE); Any ideas? Thanks!

• multiple key ranges as parameters to a couchdb view

  - by kolosy

  is there a way to send multiple startKey/endKey pairs to a view, akin to the keys: [] array that can be posted for keys? the underlying problem - let's say my documents have "categories" and timestamps. if i want all documents in the "foo" category that have a timestamp that's within the last two hours, it's simple: function (doc) { emit([doc.category, doc.timestamp], null); } and then query as GET server:5894/.../myview?startKey=[foo, |now - 2 hours|]&endkey=[foo, |now|] the problem comes when i want something in categories foo or bar, within the last two hours. if i didn't care about time, i could just pull directly by key through the keys collection. unfortunately, i have no such option with ranges. what i ended up doing in the meantime is rounding the timestamp to two-hour blocks, and then multiplexing the query out: POST server:5894/.../myview keys=[[foo, 0 hours], [foo, 2 hours], [bar, 0 hours], [bar, 2 hours]] it works, but will get messy if i want to go back a large amount of time (in relationship to the blocksize)

• mySQL auto increment problem: Duplicate entry '4294967295' for key 1

  - by Josh

  I have a table of emails. The last record in there for an auto increment id is 3780, which is a legit record. Any new record I now insert is being inserted right there. However, in my logs I have the occasional: Query FAIL: INSERT INTO mail.messages (timestamp_queue) VALUES (:time); Array ( [0] => 23000 [1] => 1062 [2] => Duplicate entry '4294967295' for key 1 ) Somehow, the autoincrement jumped up to the INT max of 4294967295 Why on god's green earth would this get jumped up so high? I have no inserts with an id field. The show status for that table, Auto_increment table now reads: 4294967296 How could something like this occur? I realize the id field should perhaps be a big int, but the worry I have is that somehow this thing jumps back up. Josh

• Hashtable with MultiDimensional Key in C#

  - by scottschulthess

  I'm basically looking for a way to access a hashtable value using a two-dimensional typed key in c#. Eventually I would be able to do something like this HashTable[1][false] = 5; int a = HashTable[1][false]; //a = 5 This is what I've been trying...hasn't worked Hashtable test = new Hashtable(); test.Add(new Dictionary<int, bool>() { { 1, true } }, 555); Dictionary<int, bool> temp = new Dictionary<int, bool>() {{1, true}}; string testz = test[temp].ToString();

• OTP or S/KEY - Conversion of Hex string into 6 readable words

  - by Garbit

  As seen in RFC2289 (S/KEY), there is a list of words that must be used when converting the hexadecimal string into a readable format. How would i go about doing so? The RFC mentions: The one-time password is therefore converted to, and accepted as, a sequence of six short (1 to 4 letter) English words. Each word is chosen from a dictionary of 2048 words; at 11 bits per word, all one-time passwords may be encoded. Read more: http://www.faqs.org/rfcs/rfc1760.html#ixzz0fu7QvXfe Does this mean converting a hex into decimal and then using that as an index for an array of words. The other thing it could be is using a text encoding e.g. 1111 might equal dog in UTF-8 encoding thanks in advance for your help!

• NSDictionary with key => String and Value => c-Style array

  - by Gautam Borad

  I need an NSDictionary which has key in the form of string (@"key1", @"key2") and value in the form of a C-style two-dimentional array (valueArray1,valueArray2) where valueArray1 is defined as : int valueArray1[8][3] = { {25,10,65},{50,30,75},{60,45,80},{75,60,10}, {10,70,80},{90,30,80},{20,15,90},{20,20,15} }; And same for valueArray2. My aim is given an NSString i need to fetch the corresponding two-dimentional array. I guess using an NSArray, instead of c-style array, will work but then i cannot initialize the arrays as done above (i have many such arrays). If, however, that is doable please let me know how. Currently the following is giving a warning "Passing argument 1 of 'dictionaryWithObjectsAndKeys:' from incompatible pointer type" : NSDictionary *myDict = [NSDictionary dictionaryWithObjectsAndKeys:valueArray1,@"key1", valueArray2,@"key2",nil];

• Posting XML via curl (command-line) without using key/value pairs

  - by Mathias Bynens

  Consider a PHP script that outputs all POST data, as follows: <?php var_dump($_POST); ?> The script is located at http://example.com/foo.php. Now, I want to post XML data to it (without using key/value pairs) using command line curl. I have tried many variations of the following: curl -H "Content-type: text/xml; charset=utf-8" --data-urlencode "<foo><bar>bazinga</foo></bar>" http://example.com/foo.php Yet none of them seem to actually post anything — according to the PHP script, $_POST is just an empty array. What am I doing wrong here?

• Setting the primary key of a object type table in Oracle

  I have two Oracle questions. How can I set the primary key of a table when the table is made up of an object type? e.g. CREATE TABLE object_names OF object_type I have created a Varray type, CREATE TYPE MULTI_TAG AS VARRAY(10) OF VARCHAR(10); but when I try to do SELECT p.tags.count FROM pg_photos p; I get an invalid identifier error on the "count" part. p.tags is a MULTI_TAG, how can I get the number of elements in the MULTI_TAG?

• use of EntityManagerFactory causing duplicate primary key exceptions

  - by bradd

  Hey guys, my goal is create an EntityManager using properties dependent on which database is in use. I've seen something like this done in all my Google searches(I made the code more basic for the purpose of this question): @PersistenceUnit private EntityManagerFactory emf; private EntityManager em; private Properties props; @PostConstruct public void createEntityManager(){ //if oracle set oracle properties else set postgres properties emf = Persistence.createEntityManagerFactory("app-x"); em = emf.createEntityManager(props); } This works and I can load Oracle or Postgres properties successfully and I can Select from either database. HOWEVER, I am running into issues when doing INSERT statements. Whenever an INSERT is done I get a duplicate primary key exception.. every time! Can anyone shed some light on why this may be happening? Thanks -Brad

• 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.

• CodeIgniter - Disallowed Key Characters via $_GET

  - by rkj

  I am getting echoed "Disallowed Key Characters." in my CodeIgniter when I have a http_cookie sent via GET from a SSL relay site (a payment gateway) to my application. My question is if there's any way that I can get this http_cookie through this "_clean_input_keys" method that cause this Disallowed-message and exits? The parameter contains a getenv("HTTP_COOKIE") set into a hidden input and needs to be used to keep the session alive even though it will be sent to the relay site and back again. The HTTP_COOKIE string looks like: &HTTP_COOKIE=PHPSESSID=775572c8c3b161bc957281aa901eb09c;%20ci_session=a%3A4%3A{s%3A10%3A%22session_id%22%3Bs%3A32%3A%229666689e0c8e4f26fb38889351765304%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A14%3A%2127.0.0.1%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A50%3A%22Mozilla%2F5.0+%28Macintosh%3B+U%3B+Intel+Mac+OS+X+10.6%3B+da%22%3Bs%3A13%3A%22last_activity%22%3Bs%3A10%3A%221271145332%22%3B}d9b9df5d8a0b51f303cbe6bb4bbe497e

• android: using listpreference and retrieving key string...

  - by Allan

  I have a settings menu that pops up and in it is a listpreference type menu. It is associated with a settings.xml file where there are 'array-strings' within it. It all works good but I don't know how to retrieve the users preference. As an example, let's say the user picks a color (red, green, or blue). The list that I've made within my 'array-strings' contain the text red, green, and blue. Within my code, I would like to do something if the user has choosen red, something else if they choose blue, etc., etc. Would I use a 'case' statement or an 'if' statement? And most importantly, how would I retrieve the users preference - the key? (am I checking for a boolean?) Help would be appreciated...thank you...
