• Need help with 2 MySql Queries. Join vs Subqueries.

  - by BugBusterX

  I have 2 tables: user: id, name message: sender_id, receiver_id, message, read_at, created_at There are 2 results I need to retrieve and I'm trying to find the best solution. I have included queries that I'm using in the very end. I need to retrieve a list of users, and also with each user have information available whether there are any unread messages from each user (them as sender, me as receiver) and whether or not there are any read messages between us ( they send I'm receiver or I send they are receivers) I need Same as above, but only those members where there has been any messaging between us, sorted by unread first, then by last message received. Can you advise please? Should this be done with joins or subqueries? In first case I do not need the count, I just need to know whether or not there is at least one unread message. I'm posting code and my current queries, please have a look when you get a chance: BTW, everything is the way I want in fist query. My concern is: In second query I would like to order by messages.created_at, but I dont think I can do that with grouping? And also I dont know if this approach is the most optimized and fast. CREATE TABLE `user` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `name` varchar(255) NOT NULL, PRIMARY KEY (`id`) ) INSERT INTO `user` VALUES (1,'User 1'),(2,'User 2'),(3,'User 3'),(4,'User 4'),(5,'User 5'); CREATE TABLE `message` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `sender_id` bigint(20) DEFAULT NULL, `receiver_id` bigint(20) DEFAULT NULL, `message` text, `read_at` datetime DEFAULT NULL, `created_at` datetime NOT NULL, PRIMARY KEY (`id`) ) INSERT INTO `message` VALUES (1,3,1,'Messge',NULL,'2010-10-10 10:10:10'),(2,1,4,'Hey','2010-10-10 10:10:12','2010-10-10 10:10:11'),(3,4,1,'Hello','2010-10-10 10:10:19','2010-10-10 10:10:15'),(4,1,4,'Again','2010-10-10 10:10:25','2010-10-10 10:10:21'),(5,3,1,'Hiii',NULL,'2010-10-10 10:10:21'); SELECT u.*, m_new.id as have_new, m.id as have_any FROM user u LEFT JOIN message m_new ON (u.id = m_new.sender_id AND m_new.receiver_id = 1 AND m_new.read_at IS NULL) LEFT JOIN message m ON ((u.id = m.sender_id AND m.receiver_id = 1) OR (u.id = m.receiver_id AND m.sender_id = 1)) GROUP BY u.id SELECT u.*, m_new.id as have_new, m.id as have_any FROM user u LEFT JOIN message m_new ON (u.id = m_new.sender_id AND m_new.receiver_id = 1 AND m_new.read_at IS NULL) LEFT JOIN message m ON ((u.id = m.sender_id AND m.receiver_id = 1) OR (u.id = m.receiver_id AND m.sender_id = 1)) where m.id IS NOT NULL GROUP BY u.id

• Unable to use getInt() but able to use getString() for a sqlite database

  - by mwrazam

  I am using a cursor to access a sqlite database I have in my app. I am having trouble using the .getInt() on my database. My database is pre-created, and I have a few cursors that perform queries to interface with the information. Several of the columns in one of the tables are set as INTEGER type. I realize that sqlite has no built in check to make sure columns are indeed INT. However, when retrieving the data, I can use the .getString() function without any issues, but calling .getInt() causes the app to crash. Below is the relevant code. If I am missing anything, please let me know, and I'll add it in. Any help is greatly appreciated. Thank you very much. Cursor: public Cursor getSkitStats(int module, int skit) { Cursor mCursor = myDataBase.rawQuery("SELECT * FROM score WHERE mod="+module+" AND skit="+skit+"", null); if (mCursor != null) { mCursor.moveToFirst(); } return mCursor; } and I am using a simple Toast call to output the result of the query: Toast.makeText(getApplicationContext(), scoreContent.getInt(0), Toast.LENGTH_SHORT).show(); The variable scoreContent is the cursor. And here is the crash output: 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1659) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1675) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.access$1500(ActivityThread.java:121) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:943) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Handler.dispatchMessage(Handler.java:99) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.os.Looper.loop(Looper.java:130) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.main(ActivityThread.java:3701) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invokeNative(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): at java.lang.reflect.Method.invoke(Method.java:507) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:866) 07-08 23:53:31.726: E/AndroidRuntime(15685): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:624) 07-08 23:53:31.726: E/AndroidRuntime(15685): at dalvik.system.NativeStart.main(Native Method) 07-08 23:53:31.726: E/AndroidRuntime(15685): Caused by: android.content.res.Resources$NotFoundException: String resource ID #0x2 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.content.res.Resources.getText(Resources.java:205) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.widget.Toast.makeText(Toast.java:258) 07-08 23:53:31.726: E/AndroidRuntime(15685): at jp.atomicideas.ne.Summary.onCreate(Summary.java:90) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 07-08 23:53:31.726: E/AndroidRuntime(15685): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1623) 07-08 23:53:31.726: E/AndroidRuntime(15685): ... 11 more

• 'Good' programming form in maintaining / updating / accessing files by entry

  - by zhermes

  Basic Question: If I'm storying/modifying data, should I access elements of a file by index hard-coded index, i.e. targetFile.getElement(5); via a hardcoded identifier (internally translated into index), i.e. target.getElementWithID("Desired Element"), or with some intermediate DESIRED_ELEMENT = 5; ... target.getElement(DESIRED_ELEMENT), etc. Background: My program (c++) stores data in lots of different 'dataFile's. I also keep a list of all of the data-files in another file---a 'listFile'---which also stores some of each one's properties (see below, but i.e. what it's name is, how many lines of information it has etc.). There is an object which manages the data files and the list file, call it a 'fileKeeper'. The entries of a listFile look something like: filename , contents name , number of lines , some more numbers ... Its definitely possible that I may add / remove fields from this list --- but in general, they'll stay static. Right now, I have a constant string array which holds the identification of each element in each entry, something like: const string fileKeeper::idKeys[] = { "FileName" , "Contents" , "NumLines" ... }; const int fileKeeper::idKeysNum = 6; // 6 - for example I'm trying to manage this stuff in 'good' programatic form. Thus, when I want to retrieve the number of lines in a file (for example), instead of having a method which just retrieves the '3'rd element... Instead I do something like: string desiredID = "NumLines"; int desiredIndex = indexForID(desiredID); string desiredElement = elementForIndex(desiredIndex); where the function indexForID() goes through the entries of idKeys until it finds desiredID then returns the index it corresponds to. And elementForIndex(index) actually goes into the listFile to retrieve the index'th element of the comma-delimited string. Problem: This still seems pretty ugly / poor-form. Is there a way I should be doing this? If not, what are some general ways in which this is usually done? Thanks!

• Figuring out QuadCurveTo's parameters

  - by Fev

  Could you guys help me figuring out QuadCurveTo's 4 parameters , I tried to find information on http://docs.oracle.com/javafx/2/api/javafx/scene/shape/QuadCurveTo.html, but it's hard for me to understand without picture , I search on google about 'Quadratic Bezier' but it shows me more than 2 coordinates, I'm confused and blind now. I know those 4 parameters draw 2 lines to control the path , but how we know/count exactly which coordinates the object will throught by only knowing those 2 path-controller. Are there some formulas? import javafx.animation.PathTransition; import javafx.animation.PathTransition.OrientationType; import javafx.application.Application; import static javafx.application.Application.launch; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.shape.MoveTo; import javafx.scene.shape.Path; import javafx.scene.shape.QuadCurveTo; import javafx.scene.shape.Rectangle; import javafx.stage.Stage; import javafx.util.Duration; public class _6 extends Application { public Rectangle r; @Override public void start(final Stage stage) { r = new Rectangle(50, 80, 80, 90); r.setFill(javafx.scene.paint.Color.ORANGE); r.setStrokeWidth(5); r.setStroke(Color.ANTIQUEWHITE); Path path = new Path(); path.getElements().add(new MoveTo(100.0f, 400.0f)); path.getElements().add(new QuadCurveTo(150.0f, 60.0f, 100.0f, 20.0f)); PathTransition pt = new PathTransition(Duration.millis(1000), path); pt.setDuration(Duration.millis(10000)); pt.setNode(r); pt.setPath(path); pt.setOrientation(OrientationType.ORTHOGONAL_TO_TANGENT); pt.setCycleCount(4000); pt.setAutoReverse(true); pt.play(); stage.setScene(new Scene(new Group(r), 500, 700)); stage.show(); } public static void main(String[] args) { launch(args); } } You can find those coordinates on this new QuadCurveTo(150.0f, 60.0f, 100.0f, 20.0f) line, and below is the picture of Quadratic Bezier

• Guilty of unsound programming

  - by TelJanini

  I was reading Robert Rossney's entry on "What's the most unsound program you've had to maintain?" found at: (What's the most unsound program you've had to maintain?) when I realized that I had inadvertently developed a near-identical application! The app consists of an HTTPListener object that grabs incoming POST requests. Based on the information in the header, I pass the body of the request to SQL Server to perform the appropriate transaction. The requests look like: <InvoiceCreate Control="389> <Invoice> <CustomerNumber>5555</CustomerNumber> <Total>300.00</Total> <RushOrder>1</RushOrder> </Invoice> </InvoiceCreate> Once it's received by the HTTPListener object, I perform the required INSERT to the Invoice table using SQL Server's built-in XML handling functionality via a stored procedure: INSERT INTO Invoice (InvoiceNumber, CustomerNumber, Total, RushOrder) SELECT @NEW_INVOICE_NUMBER, @XML.value('(InvoiceCreate/Invoice/CustomerNumber)[1]', 'varchar(10)'), @XML.value('(InvoiceCreate/Invoice/Total)[1]', 'varchar(10)'), @XML.value('(InvoiceCreate/Invoice/Total)[1]', 'varchar(10)') I then use another SELECT statement in the same stored procedure to return the value of the new Invoice Number that was inserted into the Invoices table: SELECT @NEW_INVOICE_NUMBER FOR XML PATH 'InvoiceCreateAck' I then read the generated XML using a SQL data reader object in C# and use it as the response of the HTTPListener object. My issue is, I'm noticing that Robert is indeed correct. All of my application logic exists inside the stored procedure, so I find myself having to do a lot of error-checking (i.e. validating the customer number and invoicenumber values) inside the stored procedure. I'm still a midlevel developer, and as such, am looking to improve. Given the original post, and my current architecture, what could I have done differently to improve the application? Are there any patterns or best practices that I could refer to? What approach would you have taken? I'm open to any and all criticism, as I'd like to do my part to reduce the amount of "unsound programming" in the world.

• 1) PasswordResets emails user when requesting password reset

  - by Surge Pedroza

  I've been trying to add a password reset for users that forget their password. The users clicks on forgot password? on sign up page.

• Wordpress Custom Post Type adding tags

  - by Nick White

  I am currently working on a Wordpress site I have created some custom Post Types all work fine create the post etc. What I need however is custom taxonomies with some of the custom Post Types, I have set this up and when adding different tags to the taxonomy it works however, when creating a post for a custom post type in the taxonomy block clicking add tag it just does a anchor link to #Member news Category-add Nothing else happens, it's not a big bug but I would however, like to fix this so it is correct for the time I go live Is this a known bug? or is there something I have probably missed when creating the custom post type? register_post_type('member_news', array( 'label' => 'Member News','description' => 'News content submitted by members of RRUKA.','public' => true,'show_ui' => true,'show_in_menu' => true,'capability_type' => 'post','hierarchical' => false,'rewrite' => array('slug' => 'member-news'),'query_var' => true,'has_archive' => true,'exclude_from_search' => false,'menu_position' => 5,'supports' => array('title','editor','excerpt','trackbacks','revisions','thumbnail','author','page-attributes',),'labels' => array ( 'name' => 'Member News', 'singular_name' => 'Member News', 'menu_name' => 'Member News', 'add_new' => 'Add Member News', 'add_new_item' => 'Add New Member News', 'edit' => 'Edit', 'edit_item' => 'Edit Member News', 'new_item' => 'New Member News', 'view' => 'View Member News', 'view_item' => 'View Member News', 'search_items' => 'Search Member News', 'not_found' => 'No Member News Found', 'not_found_in_trash' => 'No Member News Found in Trash', 'parent' => 'Parent Member News', ),) ); Any information on this would be very welcome Thanks in advanced

• How to read & write contents of a div from localstorage in chrome extensions?

  - by Minas Abovyan

  I am trying to build an extension that will allow users to put some parameters into a text box in the popup, generate a link using that information and add it to the said popup. I have all that working, but needless to say, it gets flushed every time the user opens the extension anew. I'd like the info that has been put in there to stay, but can't seem to get it to work. Here's what I have thus far: manifest.json { "manifest_version": 2, "name": "Test", "description": "Test Extension", "version": "1.0", "permissions": [ "http://*/*", "https://*/*" ], "browser_action": { "default_title": "This is a test", "default_popup": "popup.html" } } popup.html <!DOCTYPE html> <html> <head> </head> <body> <div id="linkContainer"/> <input type="text" id="catsList"/> <button type="button" id="addToList">Add</button> <script src="popup.js"></script> </body> </html> popup.js function addCats() { var a = document.createElement('a'); a.appendChild(document.createTextNode(document.getElementById('catsList').value)); a.setAttribute('href', 'http://google.com'); var p = document.createElement('p'); p.appendChild(a) document.getElementById('linkContainer').appendChild(p); indexLinks() } function indexLinks() { var links = document.getElementsByTagName("a"); for (var i = 0; i < links.length; i++) { (function () { var ln = links[i]; var location = ln.href; ln.onclick = function () { chrome.tabs.create({active: true, url: location}); }; })(); } }; document.getElementById('addToList').onclick = addCats; My guess is that I need something along the lines of localStorage['cointainer'] = document.getElementById('linkContainer'); at the end of addCats() and a call to something like function loadLocalStorage() { var container = document.getElementById('linkContainer'); container.innerHTML = localStorage['container']; } at the beginning, but doing that didn't work. Not sure what's going wrong. Also,if there is a different way to save users' additions, I'd be open to them.

• Convert Object Hierachey to Object Array

  - by Killercam

  All, I want to create an object array foo[], where the constructor for Foo is public Foo(string name, string discription){} I have a database object which has a structure (not incuding stored procedures, functions or views for simplicity) like public class Database { public string name { get; set; } public string filename { get; set; } public List<Table> tables { get; set; } public Database(string name, string filename) { this.name = name; this.filename = filename; } } protected internal class Table { public string name { get; set; } public List<Column> columns { get; set;} public Table(string name, List<Column> columns) { this.name = name; this.columns = columns; } } protected internal class Column { public string name { get; set; } public string type { get; set; } public Column(string name, string type, int maxLength, bool isNullable) { this.name = name; this.type = type; } } I would like to know the quickest way to add Column and Table information to the Foo[] object array? Clearly I can do List<Foo> fooList = new List<Foo>(); foreach (Table t in database.tables) { fooList.Add(new Foo(t.Name, "Some Description")); foreach (Column c in t.columns) fooList.Add(new Foo(c.Name, "Some Description")); } Foo[] fooArr = fooList.ToArray<Foo>(); But is there a quicker way? Clearly LINQ is likely to be slower for a query that does a simalar operation, but I care allot about speed here so any advice would be appreciated. Perhaps the use of a HashSet would be the way to go as there will not be duplicate entries... Thanks for your time.

• With custom binding for Masonry how would I resize the container appropriately

  - by BigDubb

  Based on the suggestion give here, and the information given here on how to make a custom bindingHandler for a forEach, I decided to attempt to write my own custom binding for a forEach and Masonry. Because the elements are added on the fly the redrawing and moving around of elements to fill the space doesn't occur. So, this functionality needed to be moved after the elements have been rendered or called after each item has been added. Here is my bindingHandler ko.bindingHandlers.masonry = { init: function (element, valueAccessor, allBindingsAccessor) { var $element = $(element), originalContent = $element.html(); $element.data("original-content", originalContent); //var msnry = new Masonry($element); return { controlsDescendantBindings: true } }, update: function (element, valueAccessor, allBindingsAccessor) { var value = ko.utils.unwrapObservable(valueAccessor()), //get the list of items items = value.items(), //get a jQuery reference to the element $element = $(element), //get the current content of the element elementContent = $element.data("original-content"); $element.html(""); var container = $element[0]; var msnry = new Masonry(container); for (var index = 0; index < items.length; index++) { (function () { //get the list of items var item = ko.utils.unwrapObservable(items[index]), $childElement = $(elementContent); ko.applyBindings(item, $childElement[0]); //add the child to the parent $element.append($childElement); msnry.appended($childElement[0]); })(); msnry.layout(); msnry.bindResize(); } } }; and the HTML implementing the handler. <div id="criteriaContainer" data-bind="masonry: { items: SearchItems.Items }"> <div class="searchCriterion control-group"> <label class="control-label" data-bind="text: Description"></label> <div class="controls"> <input type="hidden" data-bind="value: Value, select2: { minimumInputLength: 3, queryUri: SearchUri(), placeholder: Placeholder(), allowClear: true }" style="width: 450px"> </div> <p data-bind="text: Value"></p> </div> </div> When this shows up on the page It stacks all if the elements rendered via the append method right on top of each other. You can see in my bindingHandler I am calling bindResize as well as layout(), neither of which seem to be having any effect. Here's a screenshot of what it looks like in the UI.

• What is the best approach in SQL to store multi-level descriptions?

  - by gime

  I need a new perspective on how to design a reliable and efficient SQL database to store multi-level arrays of data. This problem applies to many situations but I came up with this example: There are hundreds of products. Each product has an undefined number of parts. Each part is built from several elements. All products are described in the same way. All parts would require the same fields to describe them (let's say: price, weight, part name), all elements of all parts also have uniform design (for example: element code, manufacturer). Plain and simple. One element may be related to only part, and each part is related to one product only. I came up with idea of three tables: Products: -------------------------------------------- prod_id prod_name prod_price prod_desc 1 hoover 120 unused next Parts: ---------------------------------------------------- part_id part_name part_price part_weight prod_id 3 engine 10 20 1 and finally Elements: --------------------------------------- el_id el_code el_manufacturer part_id 1 BFG12 GE 3 Now, select a desired product, select all from PARTS where prod_id is the same, and then select all from ELEMENTS where part_id matches - after multiple queries you've got all data. I'm just not sure if this is the right approach. I've got also another idea, without ELEMENTS table. That would decrease queries but I'm a bit afraid it might be lame and bad practice. Instead of ELEMENTS table there are two more fields in the PARTS table, so it looks like this: part_id, part_name, part_price, part_weight, prod_id, part_el_code, part_el_manufacturer they would be text type, and for each part, information about elements would be stored as strings, this way: part_el_code | code_of_element1; code_of_element2; code_of_element3 part_el_manufacturer | manuf_of_element1; manuf_of_element2; manuf_of_element3 Then all we need is to explode() data from those fields, and we get arrays, easy to display. Of course this is not perfect and has some limitations, but is this idea ok? Or should I just go with the first idea? Or maybe there is a better approach to this problem? It's really hard to describe it in few words, and that means it's hard to search for answer. Also, understanding the principles of designing databases is not that easy as it seems.

• Change xml attribute in foreach statement c#

  - by user1913479

  I need to save XML-attribute value in a database, using information if checkbox is checked. If checkbox is checked, the attribute value is "TRUE", otherwise it's false. When I use foreach statement, the last enumerated value is usually assigned. Here is the part of my code: XmlAttribute xmlAttribute = xmlDoc.CreateAttribute("BooleanValue"); foreach (string value in list) //list is a List<object> { XmlNode xmlNode = xmlDoc.CreateNode(XmlNodeType.Element, "VALUE", ""); if (checkBox1.Checked || checkBox2.Checked || checkBox3.Checked) xmlAttribute.Value = "TRUE"; if (!checkBox1.Checked || !checkBox2.Checked || !checkBox3.Checked) xmlAttribute.Value = "FALSE"; xmlNode.Attributes.Append(xmlAttribute); xmlNode.InnerText = val; childNode.AppendChild(xmlNode); } When I run my application, I get an XML attribute xmlAttribute "FALSE" value anyway. What I need to have: I need to have the following XML: <ROOT><NODE><VALUE ATTRIBUTE="TRUE">Value 1</VALUE></NODE> <NODE><VALUE ATTRIBUTE="TRUE">Value 2</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 3</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 4</VALUE></NODE> <NODE><VALUE ATTRIBUTE="TRUE">Value 5</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 6</VALUE></NODE> </ROOT> What I actually get: <ROOT><NODE><VALUE ATTRIBUTE="FALSE">Value 1</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 2</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 3</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 4</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 5</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 6</VALUE></NODE> </ROOT> Because in C# FALSE value is stayed at last position in foreach loop The question is: how do I do to assign the correct values of my attribute. Thanks

I'm currently experimenting with arrays in PHP, and I created a fake environment where a team's information will be displayed. $t1 = array ( "basicInfo" => array ( "The Sineps", "December 25, 2010", "lemonpole" ), "overallRecord" => array (0, 0, 0, 0), "overallSeasons" => array ( 1 => array (14, 0, 0), 2 => array (9, 5, 2), 3 => array (12, 4, 0), 4 => array (3, 11, 2) ), "games" => array ( "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />", "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />", "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />", "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />" ), "seasonHistory" => array ( "Season I", "Season II", "Season III", "Season IV" ), "divisions" => array ( "Open", "Main", "Main", "Invite" ) ); // Displays the seasons the team has been in along // with the record of each season. function seasonHistory() { // Make array variable local-scope. global $t1; // Count the number of seasons. $numrows = count($t1["seasonHistory"]); // Loop through all the variables until // it reaches the last entry made and display // each item seperately. for($v = 0; $v <= $numrows; $v++) { // Echo each season. echo "<tr><td>{$t1["games"][$v]}</td>"; echo "<td>{$t1["seasonHistory"][$v]}</td>"; echo "<td>{$t1["divisions"][$v]}</td></tr>"; } } I have tested several possible problems out and after narrowing them down I have come down to one conclusion and that is my function is not connecting to the array for some reason. I don't know what else to do because I thought making the array global would fix that problem. What works: I can echo $t1["games"][0] on the page I need it to display and it gives me the content. I tried echo $t1["games"][0] INSIDE the function and then calling the function and it doesn't display anything.

• [C#] How to do a search from a list with non-prefix keywords

  - by aNui

  First of all, sorry if my english or my post got any mistakes. I am programming a program to search the name from the list and I need to find them if the keyword is not in front of the names (that's what I mean non-prefix) e.g. if I my list is the music instruments and I type "guit" to the search textbox. It should find the names "Guitar, Guitarrón, Acoustic Guitar, Bass Guitar, ..." or something like this Longdo Dictionary's search suggestion. here is my simple and stupid algorithm (that's all I can do) const int SEARCHROWLIMIT = 30; private string[] DoSearch(string Input, string[] ListToSearch) { List<string> FoundNames = new List<string>(); int max = 0; bool over = false; for (int k = 0; !over; k++) { foreach (string item in ListToSearch) { max = (max > item.Length) ? max : item.Length; if (k > item.Length) continue; if (k >= max) { over = true; break; } if (!Input.Equals("Search") && item.Substring(k, item.Length - k).StartsWith(Input, StringComparison.OrdinalIgnoreCase)) { bool exist = false; int i = 0; while (!exist && i < FoundNames.Count) { if (item.Equals(FoundNames[i])) { exist = true; break; } i++; } if (!exist && FoundNames.Count < SEARCHROWLIMIT) FoundNames.Add(item); else if (FoundNames.Count >= SEARCHROWLIMIT) over = true; } } } return FoundNames.ToArray(); } I think this algorithm is too slow for a large number of names and after several trial-and-error, I decided to add SEARCHROWLIMIT to breaks the operation And I also think there're some readymade methods that can do that. And another problem is I need to search music instruments by a category like strings, percussions, ... and by the country of origins. So I need to search them with filter by type and country. please help me. P.S. Me and my friends are just student from Thailand and developing the project to compete in Microsoft Imagine Cup 2010 and please become fan on our facebook page [KRATIB][3]. And we're so sorry we don't have much information in English but you can talk to us in English.

• PHP-OOP extending two classes?

  - by user1292810

  I am very beginner to OOP and now I am trying to write some PHP class to connect with FTP server. class ftpConnect { private $server; private $user; private $password; private $connection_id; private $connection_correct = false; public function __construct($server, $user = "anonymous", $password = "[email protected]") { $this->server = $server; $this->user = $user; $this->password = $password; $this->connection_id = ftp_connect($this->server); $this->connection_correct = ftp_login($this->connection_id, $this->user, $this->password); if ( (!$this->connection_id) || (!$this->connection_correct) ){ echo "Error! Couldn't connect to $this->server"; var_dump($this->connection_id); var_dump($this->connection_correct); return false; } else { echo "Successfully connected to $this->server, user: $this->user"; $this->connection_correct = true; return true; } } } I reckon that body of the class is insignificant at the moment. Main issue is that I have some problems with understanding OOP idea. I wanted to add sending emails every time, when the code is run. I have downloaded PHPMailer Class and extended my class with it: class ftpConnect extends PHPMailer {...} I have added some variables and methods and everything works as expected to that point. I thought: why not to add storing everything in database. Everytime user runs above code, proper information should be stored in database. I could edit my ftpConnect class and add database connecting to the constructor, and some other methods to updating tables. But database connecting and all that stuff could be used by other classes in the future, so it definitely should be implemented in seperate class. But my "main" ftpConnect class already extends one class and could not extend not a single one more. I have no idea how can I resolve this problem. Maybe my ftpConnect class is to complex and I should somehow divide it into couple smaller classes? Any help is much appreciated.

• SFTP not supported error with PHP & cURL

  - by Bad Programmer

  I followed the advice from this Stack Overflow question thread, but I keep hitting a snag. I am receiving the following error message: Unsupported protocol: sftp Here is my code: $ch = curl_init(); if(!$ch) { $error = curl_error($ch); die("cURL session could not be initiated. ERROR: $error.""); } $fp = fopen($docname, 'r'); if(!$fp) { $error = curl_error($ch); die("$docname could not be read."); } curl_setopt($ch, CURLOPT_URL, "sftp://$user_name:$user_pass@$server:22/$docname"); curl_setopt($ch, CURLOPT_UPLOAD, 1); curl_setopt($ch, CURLOPT_PROTOCOLS, CURLPROTO_SFTP); curl_setopt($ch, CURLOPT_INFILE, $fp); curl_setopt($ch, CURLOPT_INFILESIZE, filesize($docname)); //this is where I get the failure $exec = curl_exec ($ch); if(!$exec) { $error = curl_error($ch); die("File $docname could not be uploaded. ERROR: $error."); } curl_close ($ch); I used the curl_version() function to see my curl information, and found that sftp doesn't seem to be in the array of supported protocols: [version_number] => 462597 [age] => 2 [features] => 1597 [ssl_version_number] => 0 [version] => 7.15.5 [host] => x86_64-redhat-linux-gnu [ssl_version] => OpenSSL/0.9.8b [libz_version] => 1.2.3 [protocols] => Array ( [0] => tftp [1] => ftp [2] => telnet [3] => dict [4] => ldap [5] => http [6] => file [7] => https [8] => ftps ) Is this a matter of my version of cURL being outdated, or is the SFTP protocol simply not supported at all? Any advice is greatly appreciated.

• Push notification is successfully sent, but the device does not receive (occasionally)

  - by ashiina

  I have been having a problem where some devices will not receive a push notification, since yesterday. The certificate / devicetoken seem to be correct, since the device used to successfully receive push notifications until yesterday. On the server-side, there are no errors or connection refusals, and the push notification seems to be successfully sent every time. But still, there are many occasions where the device does not correctly receive the push. Some surrounding information: I am doing this on the production environment. No errors / connection refusals on the server-side I am sending the exactly same JSON everytime. 2 of our devices are not receiving the push notification AT ALL since yesterday 1 of our device receives push notifications at a lower success rate (about 70%) than yesterday 1~2 of our devices still receive push notifications successfully even now. All of the above devices were able to receive push notifications properly on the production environment until yesterday. There is no difference in the server-side result for when the push is successful, and when the device doesn't receive it... Therefore it is virtually impossible to identify the problem. This is the server-side PHP code I am using: $ctx = stream_context_create(); stream_context_set_option($ctx, 'ssl', 'local_cert', $this->apnsData[$development]['certificate']); $fp = stream_socket_client($this->apnsData[$development]['ssl'], $error, $errorString, 100, (STREAM_CLIENT_C ONNECT|STREAM_CLIENT_PERSISTENT), $ctx); if(!$fp){ $this->_pushFailed($pid); $this->_triggerError("Failed to connect to APNS: {$error} {$errorString}."); } else { $msg = chr(0).pack("n",32).pack('H*',$token).pack("n",strlen($message)).$message; $fwrite = fwrite($fp, $msg); if(!$fwrite) { error_log("[APNS] push failed..."); $this->_pushFailed($pid); $this->_triggerError("Failed writing to stream.", E_USER_ERROR); } else { error_log("[APNS] push successful! ::: $token -> $message ($fwrite bytes)"); } } fclose($fp); The log tells me that the push was successful (Cutting out the token for privacy) : [Wed Dec 12 11:42:00 2012] [error] [client 10.161.6.177] [APNS] push successful! ::: aa4f******44 -> {"aps":{"alert":{"body":"\\u300casdfasdf\\u300d","action-loc-key":"OK"},"badge":4,"sound":"chime"}} (134 bytes) Is there any way I can get help on this problem? Or is there anybody who is having the same problem?? Please help! I am getting complaints from some users on this....

• Div not expanding even with content inside

  - by Aiden Ryan

  I have a stack of divs inside of each other, all of which have an ID which specifies CSS only. But for some reason the surrounding DIV tag only expands to it's anointed height value, and not it's default auto, meaning that although the content is inside, the backing DIV is only a specific height. I need it to adjust the heigh to the size of whatever is inside of it (As there will be user submitted data being echoed out possibly in paragraphs with 500+ words.) Here is my HTML <div id="albumhold"> <div id="albumpic">Pic here</div> <div id="infohold"> <div id="albumhead">Name | Date</div> <div id="albuminfo">Information</div> </div> And the CSS for the HTML code: #albumhold { width: 920px; padding: 10px; height: auto; border: 1px solid #E1E1E1; margin-left: auto; margin-right: auto; background-color: #E1E1E1; background-image: url(../global-images/albumback.png); background-position: top center; background-repeat: repeat-x; } #albumpic { display: block; height: 110px; width: 110px; float: left; border: 1px solid #000; } #infohold { width: 800px; background-color: #CCC; float: right; height: 20px; } #albumhead { width: 800px; height: 20px; text-indent: 10px; border: 1px solid #000; color: #09F; } #albuminfo { margin-top: 5px; width: 800px; float: right; color: #09F; word-wrap:break-word; } Help is greatly appreciated.

• Changing a select input to a checkbox acting as an on/off toggle switch in Rails

  - by Ribena

  I have a set of 7 dropdown inputs allowing admins to say whether they are open or closed for business on a given day. I'd like that changed to 7 open/closed switches (presumably styled checkboxes?) but can't figure out how to do this! Here are the relevant bits of code I currently have (prior to any change): app/view/backend/inventory_pool/edit.html.haml - content_for :title, @inventory_pool = form_for [:backend, @inventory_pool], html: {name: "form"} do |f| .content - if is_admin? %a.button{:href => root_path}= _("Cancel") %button.button{:type => :submit}= _("Save %s") % _("Inventory Pool") %section %h2= _("Basic Information") .inner .field.text .key %h3= "#{_("Print Contracts")}" %p.description .value .input %input{type: "checkbox", name: "inventory_pool[print_contracts]", checked: @inventory_pool.print_contracts} %section#workdays %h2= _("Workdays") .inner - [1,2,3,4,5,6,0].each do |i| .field.text .key %h3= "#{I18n.t('date.day_names')[i]}" .value .input %select{:name => "store[workday_attributes][workdays][]"} %option{:label => _("Open"), :value => Workday::WORKDAYS[i]}= _("Open") %option{:label => _("Closed"), :value => "", :selected => @store.workday.closed_days.include?(i) ? true : nil}= _("Closed") app/models/workday.rb class Workday < ActiveRecord::Base belongs_to :inventory_pool WORKDAYS = ["sunday", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday"] def is_open_on?(date) return false if date.nil? case date.wday when 1 return monday when 2 return tuesday when 3 return wednesday when 4 return thursday when 5 return friday when 6 return saturday when 0 return sunday else return false #Should not be reached end end def closed_days days = [] days << 0 unless sunday days << 1 unless monday days << 2 unless tuesday days << 3 unless wednesday days << 4 unless thursday days << 5 unless friday days << 6 unless saturday days end def workdays=(wdays) WORKDAYS.each {|workday| write_attribute(workday, wdays.include?(workday) ? true : false)} end end And in app/controllers/backend/inventory_pools_controller I have this (abridged): def update @inventory_pool ||= InventoryPool.find(params[:id]) process_params params[:inventory_pool] end def process_params ip ip[:print_contracts] ||= "false" # unchecked checkboxes are *not* being sent ip[:workday_attributes][:workdays].delete "" if ip[:workday_attributes] end

• Looking for some help working with premultiplied alpha

  - by user315142

  I am trying to update a source image with the contents of multiple destination images. From what I can tell using premultiplied alpha is the way to go with this, but I think I am doing something wrong (function below). the image I am starting with is initialized with all ARGB values set to 0. When I run the function once the resulting image looks great, but when I start compositing on any others all the pixels that have alpha information get really messed up. Does anyone know if I am doing something glaringly wrong or if there is something extra I need to do to modify the color values? void CompositeImage(unsigned char *src, unsigned char *dest, int srcW, int srcH){ int w = srcW; int h = srcH; int px0; int px1; int px2; int px3; int inverseAlpha; int r; int g; int b; int a; int y; int x; for (y = 0; y < h; y++) { for (x= 0; x< w*4; x+=4) { // pixel number px0 = (y*w*4) + x; px1 = (y*w*4) + (x+1); px2 = (y*w*4) + (x+2); px3 = (y*w*4) + (x+3); inverseAlpha = 1 - src[px3]; // create new values r = src[px0] + inverseAlpha * dest[px0]; g = src[px1] + inverseAlpha * dest[px1]; b = src[px2] + inverseAlpha * dest[px2]; a = src[px3] + inverseAlpha * dest[px3]; // update destination image dest[px0] = r; dest[px1] = g; dest[px2] = b; dest[px3] = a; } } }

• Apache SSO through Kerberos using Machine Account

  - by watkipet

  I'm attempting to get Apache on Ubuntu 12.04 to authenticate users via Kerberos SSO to a Windows 2008 Active Directory server. Here are a few things that make my situation different: I don't have administrative access to the Windows Server (nor will I ever have access). I also cannot have any changes to the server made on my behalf. I've joined Ubuntu server to the Active Directory using PBIS open. Users can log into the Ubuntu server using their AD credentials. kinit also works fine for each user. Since I can't change AD (except for adding new machines and SPNs), I cannot add a service account for Apache on Ubuntu. Since I can't add I service account, I have to use the machine keytab (/etc/krb5.keytab), or at least use the machine password in another keytab. Right now I'm using the machine keytab and giving Apache readonly access (bad idea, I know). I've already added the SPN using net ads keytab add HTTP -U Since I'm using Ubuntu 12.04, the only encoding types that get added during "net ads keytab add" are arcfour-hmac, des-cbc-crc, and des-cbc-md5. PBIS adds the AES encoding types to the host and cifs principals when it joins the domain, but I have yet to get "net ads keytab add" to do this. ktpass and setspn are out of the question because of #1 above. I've configured (for Kerberos SSO) and tested both IE 8 Firefox. I'm using the following configuration in my Apache site config: <Location /secured> AuthType Kerberos AuthName "Kerberos Login" KrbMethodNegotiate On KrbMethodK5Passwd On KrbAuthRealms DOMAIN.COM Krb5KeyTab /etc/krb5.keytab KrbLocalUserMapping On require valid-user </Location> When Firefox tries to connect get the following in Apache's error.log (LogLevel debug): [Wed Oct 23 13:48:31 2013] [debug] src/mod_auth_kerb.c(1628): [client 192.168.0.2] kerb_authenticate_user entered with user (NULL) and auth_type Kerberos [Wed Oct 23 13:48:31 2013] [debug] mod_deflate.c(615): [client 192.168.0.2] Zlib: Compressed 477 to 322 : URL /secured [Wed Oct 23 13:48:37 2013] [debug] src/mod_auth_kerb.c(1628): [client 192.168.0.2] kerb_authenticate_user entered with user (NULL) and auth_type Kerberos [Wed Oct 23 13:48:37 2013] [debug] src/mod_auth_kerb.c(994): [client 192.168.0.2] Using HTTP/[email protected] as server principal for password verification [Wed Oct 23 13:48:37 2013] [debug] src/mod_auth_kerb.c(698): [client 192.168.0.2] Trying to get TGT for user [email protected] [Wed Oct 23 13:48:37 2013] [debug] src/mod_auth_kerb.c(609): [client 192.168.0.2] Trying to verify authenticity of KDC using principal HTTP/[email protected] [Wed Oct 23 13:48:37 2013] [debug] src/mod_auth_kerb.c(652): [client 192.168.0.2] krb5_rd_req() failed when verifying KDC [Wed Oct 23 13:48:37 2013] [error] [client 192.168.0.2] failed to verify krb5 credentials: Decrypt integrity check failed [Wed Oct 23 13:48:37 2013] [debug] src/mod_auth_kerb.c(1073): [client 192.168.0.2] kerb_authenticate_user_krb5pwd ret=401 user=(NULL) authtype=(NULL) [Wed Oct 23 13:48:37 2013] [debug] mod_deflate.c(615): [client 192.168.0.2] Zlib: Compressed 477 to 322 : URL /secured When IE 8 tries to connect I get: [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1628): [client 192.168.0.2] kerb_authenticate_user entered with user (NULL) and auth_type Kerberos [Wed Oct 23 14:03:30 2013] [debug] mod_deflate.c(615): [client 192.168.0.2] Zlib: Compressed 477 to 322 : URL /secured [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1628): [client 192.168.0.2] kerb_authenticate_user entered with user (NULL) and auth_type Kerberos [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1240): [client 192.168.0.2] Acquiring creds for HTTP@apache_server [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1385): [client 192.168.0.2] Verifying client data using KRB5 GSS-API [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1401): [client 192.168.0.2] Client didn't delegate us their credential [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1420): [client 192.168.0.2] GSS-API token of length 9 bytes will be sent back [Wed Oct 23 14:03:30 2013] [debug] src/mod_auth_kerb.c(1101): [client 192.168.0.2] GSS-API major_status:000d0000, minor_status:000186a5 [Wed Oct 23 14:03:30 2013] [error] [client 192.168.0.2] gss_accept_sec_context() failed: Unspecified GSS failure.

• Can't get MySQL to install

  - by James Marthenal

  I'd like to think I know what I'm doing in a Unix shell but maybe not. I made a mistake in a configuration file for MySQL, so I decided to just uninstall it and then reinstall it, so I did: sudo apt-get --purge remove mysql-server mysql-server-5.0 mysql-client The files were deleted, so I then tried to install it, but it didn't ask me for a root password or anything else, so I uninstalled it using the above command again and then did sudo rm -rf /etc/mysql sudo rm /etc/init.d/mysql sudo rm -rf /var/lib/mysql* I then restarted the computer then installed it again: sudo apt-get install mysql-server mysql-client It asked for a root password, and everything looked like it would work, until I saw this: $ sudo apt-get install mysql-server mysql-client Reading package lists...

• Configuring Jenkins for running with BitBucket

  - by Claus

  I'm trying to setup Jenkins on my mac mini in order to pull my iOS project source code from BitBucket and build it automatically. I've already gone through the major well know problems generating the ssh keys,uploading them in BitBucket,performing an ssh connection by console for adding the host to the well know list (you can find all my adventure here and here). Now,there are 3 user in my system: A,B and Shared. When I installed Jenkins it automatically placed itself in Shared, but I generated the ssh keys with the user A. So just to be clear In the A home directory there is an .ssh directory with public and private keys. When I try to run by Jenkins job I get this error message: Started by user anonymous Building in workspace /Users/Shared/Jenkins/Home/jobs/myprojectAdHocBuild/workspace Checkout:workspace / /Users/Shared/Jenkins/Home/jobs/myprojectAdHocBuild/workspace - hudson.remoting.LocalChannel@625cb0bb Using strategy: Default Cloning the remote Git repository Cloning repository [email protected]:myuser/myproject.git git --version git version 1.8.0 ERROR: Error cloning remote repo 'origin' : Could not clone [email protected]:myuser/myproject.git hudson.plugins.git.GitException: Could not clone [email protected]:myuser/myproject.git at hudson.plugins.git.GitAPI.clone(GitAPI.java:271) at hudson.plugins.git.GitSCM$2.invoke(GitSCM.java:1036) at hudson.plugins.git.GitSCM$2.invoke(GitSCM.java:978) at hudson.FilePath.act(FilePath.java:851) at hudson.FilePath.act(FilePath.java:824) at hudson.plugins.git.GitSCM.determineRevisionToBuild(GitSCM.java:978) at hudson.plugins.git.GitSCM.checkout(GitSCM.java:1134) at hudson.model.AbstractProject.checkout(AbstractProject.java:1325) at hudson.model.AbstractBuild$AbstractBuildExecution.defaultCheckout(AbstractBuild.java:676) at jenkins.scm.SCMCheckoutStrategy.checkout(SCMCheckoutStrategy.java:88) at hudson.model.AbstractBuild$AbstractBuildExecution.run(AbstractBuild.java:581) at hudson.model.Run.execute(Run.java:1516) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:236) Caused by: hudson.plugins.git.GitException: Command "/usr/local/git/bin/git clone --progress -o origin [email protected]:myuser/myproject.git /Users/Shared/Jenkins/Home/jobs/myprojectAdHocBuild/workspace" returned status code 128: stdout: Cloning into '/Users/Shared/Jenkins/Home/jobs/myprojectAdHocBuild/workspace'... stderr: Host key verification failed. fatal: Could not read from remote repository.

It looks like Jenkins is trying to run a command with a user which doesn't have permission to retrieve the appropriate keys from my .ssh directory.Not really sure.Maybe this output can help: MacMini:~ myuser$ ps axu | grep "/jenkins" myuser 11660 0.0 4.6 2918124 97096 ??

• postfix with mailman

  - by Thufir

  What should happen is that [email protected] should be delivered to that users inbox on localhost, user@localhost. Thunderbird works fine at reading user@localhost. I'm just using a small portion of postfix-dovecot with Ubuntu mailman. How can I get postfix to recognize the FQDN and deliver them to a localhost inbox? root@dur:~# root@dur:~# tail /var/log/mail.err;tail /var/log/mailman/subscribe;postconf -n Aug 27 18:59:16 dur dovecot: lda(root): Error: chdir(/root) failed: Permission denied Aug 27 18:59:16 dur dovecot: lda(root): Error: user root: Initialization failed: Initializing mail storage from mail_location setting failed: stat(/root/Maildir) failed: Permission denied (euid=65534(nobody) egid=65534(nogroup) missing +x perm: /root, dir owned by 0:0 mode=0700) Aug 27 18:59:16 dur dovecot: lda(root): Fatal: Invalid user settings.
