  • Optimize MySQL query (ngrams, COUNT(), GROUP BY, ORDER BY)

    - by Gerardo
    I have a database with thousands of companies and their locations. I have implemented n-grams to optimize search. I am making one query to retrieve all the companies that match with the search query and another one to get a list with their locations and the number of companies in each location. The query I am trying to optimize is the latter. Maybe the problem is this: Every company ('anunciante') has a field ('estado') to make logical deletes. So, if 'estado' equals 1, the company should be retrieved. When I run the EXPLAIN command, it shows that it goes through almost 40k rows, when the actual result (the reality matching companies) are 80. How can I optimize this? This is my query (XXX represent the n-grams for the search query): SELECT provincias.provincia AS provincia, provincias.id, COUNT(*) AS cantidad FROM anunciantes JOIN anunciante_invertido AS a_i0 ON anunciantes.id = a_i0.id_anunciante JOIN indice_invertido AS indice0 ON a_i0.id_invertido = indice0.id LEFT OUTER JOIN domicilios ON anunciantes.id = domicilios.id_anunciante LEFT OUTER JOIN localidades ON domicilios.id_localidad = localidades.id LEFT OUTER JOIN provincias ON provincias.id = localidades.id_provincia WHERE anunciantes.estado = 1 AND indice0.id IN (SELECT invertido_ngrama.id_palabra FROM invertido_ngrama JOIN ngrama ON ngrama.id = invertido_ngrama.id_ngrama WHERE ngrama.ngrama = 'XXX') AND indice0.id IN (SELECT invertido_ngrama.id_palabra FROM invertido_ngrama JOIN ngrama ON ngrama.id = invertido_ngrama.id_ngrama WHERE ngrama.ngrama = 'XXX') AND indice0.id IN (SELECT invertido_ngrama.id_palabra FROM invertido_ngrama JOIN ngrama ON ngrama.id = invertido_ngrama.id_ngrama WHERE ngrama.ngrama = 'XXX') AND indice0.id IN (SELECT invertido_ngrama.id_palabra FROM invertido_ngrama JOIN ngrama ON ngrama.id = invertido_ngrama.id_ngrama WHERE ngrama.ngrama = 'XXX') AND indice0.id IN (SELECT invertido_ngrama.id_palabra FROM invertido_ngrama JOIN ngrama ON ngrama.id = invertido_ngrama.id_ngrama WHERE ngrama.ngrama = 'XXX') GROUP BY provincias.id ORDER BY cantidad DESC And this is the query explained (hope it can be read in this format): id select_type table type possible_keys key key_len ref rows Extra 1 PRIMARY anunciantes ref PRIMARY,estado estado 1 const 36669 Using index; Using temporary; Using filesort 1 PRIMARY domicilios ref id_anunciante id_anunciante 4 db84771_viaempresas.anunciantes.id 1 1 PRIMARY localidades eq_ref PRIMARY PRIMARY 4 db84771_viaempresas.domicilios.id_localidad 1 1 PRIMARY provincias eq_ref PRIMARY PRIMARY 4 db84771_viaempresas.localidades.id_provincia 1 1 PRIMARY a_i0 ref PRIMARY,id_anunciante,id_invertido PRIMARY 4 db84771_viaempresas.anunciantes.id 1 Using where; Using index 1 PRIMARY indice0 eq_ref PRIMARY PRIMARY 4 db84771_viaempresas.a_i0.id_invertido 1 Using index 6 DEPENDENT SUBQUERY ngrama const PRIMARY,ngrama ngrama 5 const 1 Using index 6 DEPENDENT SUBQUERY invertido_ngrama eq_ref PRIMARY,id_palabra,id_ngrama PRIMARY 8 func,const 1 Using index 5 DEPENDENT SUBQUERY ngrama const PRIMARY,ngrama ngrama 5 const 1 Using index 5 DEPENDENT SUBQUERY invertido_ngrama eq_ref PRIMARY,id_palabra,id_ngrama PRIMARY 8 func,const 1 Using index 4 DEPENDENT SUBQUERY ngrama const PRIMARY,ngrama ngrama 5 const 1 Using index 4 DEPENDENT SUBQUERY invertido_ngrama eq_ref PRIMARY,id_palabra,id_ngrama PRIMARY 8 func,const 1 Using index 3 DEPENDENT SUBQUERY ngrama const PRIMARY,ngrama ngrama 5 const 1 Using index 3 DEPENDENT SUBQUERY invertido_ngrama eq_ref PRIMARY,id_palabra,id_ngrama PRIMARY 8 func,const 1 Using index 2 DEPENDENT SUBQUERY ngrama const PRIMARY,ngrama ngrama 5 const 1 Using index 2 DEPENDENT SUBQUERY invertido_ngrama eq_ref PRIMARY,id_palabra,id_ngrama PRIMARY 8 func,const 1 Using index

  • Array within Form collecting multiple values with the same name possible?

    - by JM4
    Good afternoon, I will first start with the goal I am trying to accomplish and then give a very basic sample of what I need to do. Goal Instead of collecting several variables and naming them with keys individually, I have decided to give in and use an array structure to handle all inputs of the same type and rules. Once I have the variables, I will validate against them and if 'ok' store them in a MySQL table. The table will hold consumer information and will need to store multiple rows of the same type of information. First Pass I will leave out the validation portion of this question because I feel I need to first understand the basics. <form action="?" method="POST" name="Form"> Member 1 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 1 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 1 Email: <input type="text" name="MemberEmail[]" /><br /> Member 2 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 2 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 2 Email: <input type="text" name="MemberEmail[]" /><br /> Member 3 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 3 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 3 Email: <input type="text" name="MemberEmail[]" /><br /> <input type="submit" name="submit" value="Continue" /> </form> I am hoping that each input given for First Name (a required field) will generate a unique key for that particular entry and not overwrite any data entered. Because I am carrying information from page to page (checkout form), I am turning the POST variables into SESSION variables then storing in a mysql database in the end. My hope is to have: <?php $conn = mysql_connect("localhost", "username", "password"); mysql_select_db("DBname",$conn); $sql = "INSERT INTO tablename VALUES ('$_SESSION[Member1FirstName]', '$_SESSION[Member1LastName]', '$_SESSION[Member1Email]', '$_SESSION[Member2FirstName]', '$_SESSION[Member2LastName]', '$_SESSION[Member2Email]', '$_SESSION[Member1FirstName]', '$_SESSION[Member3LastName]', '$_SESSION[Member3Email]')"; $result = mysql_query($sql, $conn) or die(mysql_error()); Header ("Location: completed.php"); ?> Where Member1, Member2, and Member3 values will appear on their own row within the table. I KNOW my code is wrong but I am giving a first shot at the overall business purpose I am trying to achieve and trying to learn how to code the right way. I am very, very new to programming so any 'baby advice' is greatly appreciated.

  • iPhone Gps logging inaccurate

    - by Martijn
    I'm logging gps points during a walk. Below it shows the function that the coordinates are saved each 5 seconds. i Did several tests but i cannot get the right accuracy i want. (When testing the sky is clear also tests in google maps shows me that the gps signal is good). here is the code: -(void)viewDidAppear:(BOOL)animated{ if (self.locationManager == nil){ self.locationManager = [[[CLLocationManager alloc] init] autorelease]; locationManager.delegate = self; // only notify under 100 m accuracy locationManager.distanceFilter = 100.0f; locationManager.desiredAccuracy= kCLLocationAccuracyBest; [locationManager startUpdatingLocation]; } } - start logging [NSTimer scheduledTimerWithTimeInterval:5 target:self selector:@selector(getData) userInfo:nil repeats:YES]; </code> <code> -(void)getData{ int distance; // re-use location. if ([ [NSString stringWithFormat:@"%1.2f",previousLat] isEqualToString:@"0.00"]){ // if previous location is not available, do nothing distance = 0; }else{ CLLocation *loc1 = [[CLLocation alloc] initWithLatitude:previousLat longitude:previousLong]; CLLocation *loc2 = [[CLLocation alloc] initWithLatitude:latGlobal longitude:longGlobal]; distance = [loc1 getDistanceFrom: loc2]; } // overwrite latGlobal with new variable previousLat = latGlobal; previousLong = longGlobal; // store location and save data to database // this part goes ok } - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { // track the time to get a new gps result (for gps indicator orb) lastPointTimestamp = [newLocation.timestamp copy]; // test that the horizontal accuracy does not indicate an invalid measurement if (newLocation.horizontalAccuracy < 0) return; // test the age of the location measurement to determine if the measurement is cached // don't rely on cached measurements NSTimeInterval locationAge = -[newLocation.timestamp timeIntervalSinceNow]; if (locationAge > 5.0) return; latGlobal = fabs(newLocation.coordinate.latitude); longGlobal= fabs(newLocation.coordinate.longitude); } I have taken a screenshot of the plot results (the walk takes 30 minutes) and an example of what i'am trying to acomplish: http://www.flickr.com/photos/21258341@N07/4623969014/ i really hope someone can put me in the right direction.

  • PHP, MySQL - My own version of SALT (I call salty) - Login Issue

    - by Fabio Anselmo
    Ok I wrote my own version of SALT I call it salty lol don't make fun of me.. Anyway the registration part of my script as follows is working 100% correctly. //generate SALTY my own version of SALT and I likes me salt.. lol function rand_string( $length ) { $chars = "ABCDEFGHIJKLMNOPQRSTUWXYZabcdefghijklmnopqrstuwxyz1234567890"; $size = strlen( $chars ); for( $i = 0; $i < $length; $i++ ) { $str .= $chars[ rand( 0, $size - 1 ) ]; } return $str; } $salty = rand_string( 256 ); //generate my extra salty pw $password = crypt('password'); $hash = $password . $salty; $newpass = $hash; //insert the data in the database include ('../../scripts/dbconnect.php'); //Update db record with my salty pw ;) // TESTED WITH AND WITHOUT SALTY //HENCE $password and $newpass mysql_query("UPDATE `Register` SET `Password` = '$password' WHERE `emailinput` = '$email'"); mysql_close($connect); However my LOGIN script is failing. I have it setup to TEST and echo if its login or not. It always returns FAILED. I entered the DB and changed the crypted salty pw to "TEST" and I got a SUCCESS. So my problem is somewhere in this LOGIN script I assume. Now I am not sure how to implement my $Salty in this. But also be advised that even without SALTY (just using crypt to store my pass) - I was still unable to perform a login successfully. And if you're gonna suggest i use blowfish - note that my webhost doesn't have it supported and i don't know how to install it. here's my login script: if (isset($_POST['formsubmitted'])) { include ('../../scripts/dbconnect.php'); $username = mysql_real_escape_string($_POST['username']); $password = crypt(mysql_real_escape_string($_POST['password'])); $qry = "SELECT ID FROM Register WHERE emailinput='$username' AND Password='$password'"; $result = mysql_query($qry); if(mysql_num_rows($result) > 0) { echo 'SUCCESS'; //START SESSION } else { echo 'FAILED'; //YOU ARE NOT LOGGED IN } } So what's wrong with this login? Why isn't it working just using the crypt/storing only crypt? How can i make it work storing both the crypt and randomly generated SALTY :) ? Ty advance

  • php download file slows

    - by hobbywebsite
    OK first off thanks for your time I wish I could give more than one point for this question. Problem: I have some music files on my site (.mp3) and I am using a php file to increment a database to count the number of downloads and to point to the file to download. For some reason this method starts at 350kb/s then slowly drops to 5kb/s which then the file says it will take 11hrs to complete. BUT if I go directly to the .mp3 file my browser brings up a player and then I can right click and "save as" which works fine complete download in 3mins. (Yes both during the same time for those that are thinking it's my connection or ISP and its not my server either.) So the only thing that I've been playing around with recently is the php.ini and the .htcaccess files. So without further ado, the php file, php.ini, and the .htcaccess: download.php <?php include("config.php"); include("opendb.php"); $filename = 'song_name'; $filedl = $filename . '.mp3'; $query = "UPDATE songs SET song_download=song_download+1 WHER song_linkname='$filename'"; mysql_query($query); header('Content-Disposition: attachment; filename='.basename($filedl)); header('Content-type: audio/mp3'); header('Content-Length: ' . filesize($filedl)); readfile('/music/' . $filename . '/' . $filedl); include("closedb.php"); ?> php.ini register_globals = off allow_url_fopen = off expose_php = Off max_input_time = 60 variables_order = "EGPCS" extension_dir = ./ upload_tmp_dir = /tmp precision = 12 SMTP = relay-hosting.secureserver.net url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset=" ; Defines the default timezone used by the date functions date.timezone = "America/Los_Angeles" .htaccess Options +FollowSymLinks RewriteEngine on RewriteCond %{HTTP_HOST} !^(www.MindCollar.com)?$ [NC] RewriteRule (.*) http://www.MindCollar.com/$1 [R=301,L] <IfModule mod_rewrite.c> RewriteEngine On ErrorDocument 404 /errors/404.php ErrorDocument 403 /errors/403.php ErrorDocument 500 /errors/500.php </IfModule> Options -Indexes Options +FollowSymlinks <Files .htaccess> deny from all </Files> thanks for you time

  • asp.net mvc & jquery dialog: What approach do I take to add items to a dropdownlist/select list with

    - by Mark Redman
    Hi, I am new to MVC and have a grasp of the basic model, but still doing everything with postbacks etc. One aspect of the UI I want to build is to have a drop-down-list of items with a button to add an item to the database and refresh the list. Achieving this with WebForms was straight forward as everything was wrapped in UpdatePanels, but what is the best approach to achieve this using MVC? Part of the markup for the list and button look like this: <table> <tr> <td><%=Html.DropDownList("JobTitleSelectList", Model.JobTitleSelectList, "(select job title)", new { @class = "data-entry-field" })%></td> <td>&nbsp;</td> <td><a id="AddJobTitleDialogLink" href="javascript: addJobTitleDialog();" title="Add Job Title"><img id="AddJobTitleButtonImage" src="/Content/Images/Icons/16x16/PlusGrey.png" border="0" /></a></td> </tr> </table> The Dialog is a standard jquery Ui dialog, looks like this: <div id="SingleTextEntryDialog" style="display:none"> <table> <tr> <td>Name:</td> <td><input id="SingleTextEntryDialogText" type="text" size="25" /></td> </tr> </table> </div> I am guessing I need to put this into a UserControl / PartialView (are they the same thing?) Also with the strongly typed View how do I pass the Model or just the SelectList Property to the UserControl or is this not the case? Nor sure if there should be form in the dialog div? or how that is going to postback via ajax. Some examples show a lot of ajax code in the page something like: $.ajax({...}); I assume doing this using jquery is more code than asp.net webforms, but there is just more code to see doing a "View Source" on a page? Your comments appreciated.

  • Alternative to Page_Load in ASP.NET (and a good WTF story)

    - by Jason
    Woo, I have a doozy of a problem (might even be one for the Daily WTF) and I'm hoping there's a solution. (My apologies for the long post...) I have been working on a website that I inherited about a month ago. One of the parts I have been working on is fixing one of the controls (essentially a dynamic header bar) so that it displays additional information as requested by my users. As part of doing this project, I created a Site.master file so that I wouldn't have to recode the header bar into every single page. When I first started doing this, it seemingly worked very well. All the pages I had developed looked great and the bar updated as it should displaying the information as it should. Well, when I dropped the Site.master (and this control) into older site pages (ones I did not specifically develop) I noticed that it looked bad on some of them, but not all of them. When I say it looked bad, basically, the control would left-align itself to the page rather than center as it should. I spent a couple hours debugging to no avail - CSS looked correct, the HTML appeared to be okay, I didn't see anything in the Javascript (although, I did miss something as I'll point out in a second), and even the old code looked correct (to the best that it could - it's not very well written). Another coworker took a look at the site and couldn't find anything at first, either. It wasn't until I just thought to look at the rendered source code of the page (I had been working in the developer view up to this point in IE8) that it became clear what was wrong. The original developer performs searches on many of the pages. To accomplish this, he queries the database for ALL the data and then loads them into Javascript arrays within the page so he can get access to them. This in itself is a huge problem because we're talking about thousands of items, and it obviously isn't scalable (and, yes, the site is slow). However, it finally clicked what was screwing up the Site.master - when he loads the data into the Javascript arrays, he writes out the data to the HTML upon Page_Load using numerous Response.Write(string) calls. The WTF (and what was messing me up) is that he inserts the Javascript before the DOCTYPE causing IE to go into quirks mode! So, because I need to at least get this release out (I'll fix the real problem later), I was wondering: is there a way I can force this Javascript to be inserted elsewhere into the HTML—after the DOCTYPE at the very least? Right now, all the Response.Write() calls are being done in the Page_Load method. I just need them to be inserted later.

  • Stop running this script, IE7 using PHP

  • How do I return clean JSON from a WCF Service?

    - by user208662
    I am trying to return some JSON from a WCF service. This service simply returns some content from my database. I can get the data. However, I am concerned about the format of my JSON. Currently, the JSON that gets returned is formatted like this: {"d":"[{\"Age\":35,\"FirstName\":\"Peyton\",\"LastName\":\"Manning\"},{\"Age\":31,\"FirstName\":\"Drew\",\"LastName\":\"Brees\"},{\"Age\":29,\"FirstName\":\"Tony\",\"LastName\":\"Romo\"}]"} In reality, I would like my JSON to be formatted as cleanly as possible. I believe (I may be incorrect), that the same collection of results, represented in clean JSON, should look like so: [{"Age":35,"FirstName":"Peyton","LastName":"Manning"},{"Age":31,"FirstName":"Drew","LastName":"Brees"},{"Age":29,"FirstName":"Tony","LastName":"Romo"}] I have no idea where the “d” is coming from. I also have no clue why the escape characters are being inserted. My entity looks like the following: [DataContract] public class Person { [DataMember] public string FirstName { get; set; } [DataMember] public string LastName { get; set; } [DataMember] public int Age { get; set; } public Person(string firstName, string lastName, int age) { this.FirstName = firstName; this.LastName = lastName; this.Age = age; } } The service that is responsible for returning the content is defined as: [ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class TestService { [OperationContract] [WebGet(ResponseFormat = WebMessageFormat.Json)] public string GetResults() { List<Person> results = new List<Person>(); results.Add(new Person("Peyton", "Manning", 35)); results.Add(new Person("Drew", "Brees", 31)); results.Add(new Person("Tony", "Romo", 29)); // Serialize the results as JSON DataContractJsonSerializer serializer = new DataContractJsonSerializer(results.GetType()); MemoryStream memoryStream = new MemoryStream(); serializer.WriteObject(memoryStream, results); // Return the results serialized as JSON string json = Encoding.Default.GetString(memoryStream.ToArray()); return json; } } How do I return “clean” JSON from a WCF service? Thank you!

  • Algorithm to split an article without breaking the reading flow or HTML code

    - by Victor Stanciu
    Hello, I have a very large database of articles, of varying lengths. The articles have HTML elements in them. I have to insert some ads (simple <script> elements) in the body of each article when it is displayed (I know, I hate ads that interrupt my reading too). Now, the problem is that each ad must be inserted at about the same position in each article. The simplest solution is to simply split the article on a fixed number of characters (without breaking words), and insert the ad code. This, however, runs the risk of inserting the ad in the middle of a HTML tag. I could go the regex way, but I was thinking about the following solution, using JS: Establish a character count threshold. For example, "the add should be inserted at about 200 words" Set accepted deviations in each direction, say -20, +20 characters. Loop through each text node inside the article, and while doing so, keep count of the total number of characters so far Once the count exceeds the threshold, make the following decision: 4.1. If count exceeds the threshold by a value lower that the positive accepted deviation (for example, 17 characters), insert the ad code just after the current text node. 4.2. If the count is greater than the sum of the threshold and the deviation, roll back to the previous text node, and make the same decision, only this time use the previous count and check if it's lower than the difference between the threshold and the deviation, and if not, insert the ad between the current node and the previous one. 4.3. If the 4.1 and 4.2 fail (which means that the previous node reached a too low character count and the current node a too high one), insert the ad after whatever character count is needed inside the current element. I know it's convoluted, but it's the first thing out of my mind and it has the advantage that, by trying to insert the ad between text nodes, perhaps it will not break the flow of the article as bad as it would if I would just stick it in (like the final 4.3 case) Here is some pseudo-code I put together, I don't trust my english-explaining skills: threshold = 200 deviation = 20 current_count = 0 for each node in article_nodes { previous_count = current_count current_count = current_count + node.length if current_count < threshold { continue // next interation } if current_count > threshold + deviation { if previous_count < threshdold - deviation { // insert ad in current node } else { // insert ad between the current and previous nodes } } else { // insert ad after the current node } break; } Am I over-complicating stuff, or am I missing a simpler, more elegant solution?

  • Using Core Data Concurrently and Reliably

    - by John Topley
    I'm building my first iOS app, which in theory should be pretty straightforward but I'm having difficulty making it sufficiently bulletproof for me to feel confident submitting it to the App Store. Briefly, the main screen has a table view, upon selecting a row it segues to another table view that displays information relevant for the selected row in a master-detail fashion. The underlying data is retrieved as JSON data from a web service once a day and then cached in a Core Data store. The data previous to that day is deleted to stop the SQLite database file from growing indefinitely. All data persistence operations are performed using Core Data, with an NSFetchedResultsController underpinning the detail table view. The problem I am seeing is that if you switch quickly between the master and detail screens several times whilst fresh data is being retrieved, parsed and saved, the app freezes or crashes completely. There seems to be some sort of race condition, maybe due to Core Data importing data in the background whilst the main thread is trying to perform a fetch, but I'm speculating. I've had trouble capturing any meaningful crash information, usually it's a SIGSEGV deep in the Core Data stack. The table below shows the actual order of events that happen when the detail table view controller is loaded: Main Thread Background Thread viewDidLoad Get JSON data (using AFNetworking) Create child NSManagedObjectContext (MOC) Parse JSON data Insert managed objects in child MOC Save child MOC Post import completion notification Receive import completion notification Save parent MOC Perform fetch and reload table view Delete old managed objects in child MOC Save child MOC Post deletion completion notification Receive deletion completion notification Save parent MOC Once the AFNetworking completion block is triggered when the JSON data has arrived, a nested NSManagedObjectContext is created and passed to an "importer" object that parses the JSON data and saves the objects to the Core Data store. The importer executes using the new performBlock method introduced in iOS 5: NSManagedObjectContext *child = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSPrivateQueueConcurrencyType]; [child setParentContext:self.managedObjectContext]; [child performBlock:^{ // Create importer instance, passing it the child MOC... }]; The importer object observes its own MOC's NSManagedObjectContextDidSaveNotification and then posts its own notification which is observed by the detail table view controller. When this notification is posted the table view controller performs a save on its own (parent) MOC. I use the same basic pattern with a "deleter" object for deleting the old data after the new data for the day has been imported. This occurs asynchronously after the new data has been fetched by the fetched results controller and the detail table view has been reloaded. One thing I am not doing is observing any merge notifications or locking any of the managed object contexts or the persistent store coordinator. Is this something I should be doing? I'm a bit unsure how to architect this all correctly so would appreciate any advice.

  • Change the Session Variable Output

    - by user567230
    Hello I am using Dreamweaver CS5 with Coldfusion 9 to build a dynamic website. I have a MS Access Database that stores login information which includes ID, FullName, FirstName, LastName, Username, Pawword, AcessLevels. My question is this: I currently have session variable to track the Username when it is entered into the login page. However I would like to use that Username to pull the User's FullName to display throughout the web pages and use for querying data. How do I change the session variable to read that when they are not entering their FullName on the login page but only Username and password. I have listed my login information code below if there is any additional information needed please let me know. This is the path for which the FullName values reside DataSource "Access" Table "Logininfo" Field "FullName" I want the FullName to be unique based on the Username submitted from the Login page. I apologize in advance for any rookie mistake I may have made I am new to this but learning fast! Ha. <cfif IsDefined("FORM.username")> <cfset MM_redirectLoginSuccess="members_page.cfm"> <cfset MM_redirectLoginFailed="sorry.cfm"> <cfquery name="MM_rsUser" datasource="Access"> SELECT FullName, Username,Password,AccessLevels FROM Logininfo WHERE Username=<cfqueryparam value="#FORM.username#" cfsqltype="cf_sql_clob" maxlength="50"> AND Password=<cfqueryparam value="#FORM.password#" cfsqltype="cf_sql_clob" maxlength="50"> </cfquery> <cfif MM_rsUser.RecordCount NEQ 0> <cftry> <cflock scope="Session" timeout="30" type="Exclusive"> <cfset Session.MM_Username=FORM.username> <cfset Session.MM_UserAuthorization=MM_rsUser.AccessLevels[1]> </cflock> <cfif IsDefined("URL.accessdenied") AND false> <cfset MM_redirectLoginSuccess=URL.accessdenied> </cfif> <cflocation url="#MM_redirectLoginSuccess#" addtoken="no"> <cfcatch type="Lock"> <!--- code for handling timeout of cflock ---> </cfcatch> </cftry> </cfif> <cflocation url="#MM_redirectLoginFailed#" addtoken="no"> <cfelse> <cfset MM_LoginAction=CGI.SCRIPT_NAME> <cfif CGI.QUERY_STRING NEQ ""> <cfset MM_LoginAction=MM_LoginAction & "?" & XMLFormat(CGI.QUERY_STRING)> </cfif> </cfif>

  • Accessing contents of NativeWindow in a HTML AIR application?

    - by Dan Scotton
    I'm currently building a HTML/JS AIR application. The application needs to display to the user a different 'window' - dependant on whether this is the first time they've launched the application or not. This part is actually fine and I have the code below to do that: if(!startUp()) { // this simply returns a boolean from a local preferences database that gets shipped with the .air // do first time stuff var windowOptions = new air.NativeWindowInitOptions(); windowOptions.systemChrome = 'none'; windowOptions.type = 'lightweight'; windowOptions.transparent = 'true'; windowOptions.resizable = 'false'; var windowBounds = new air.Rectangle(300, 300, 596, 490); var newHtmlLoader = air.HTMLLoader.createRootWindow(true, windowOptions, true, windowBounds); newHtmlLoader.load(new air.URLRequest('cover.html')); } else { // display default window // just set nativeWindow.visible = true (loaded from application.xml) } However, what I want to be able to do is manipulate the html content from within cover.html after it has loaded up. There seems to be plenty of tutorials online of how to move, resize, etc. the NativeWindow, but I simply want access to the NativeWindow's HTML content. For example, how would I add a new paragraph to that page? I've tried the following: newHtmlLoader.window.opener = window; var doc = newHtmlLoader.window.opener.document.documentElement; Using AIR's Introspector console, ....log(doc) returns [object HTMLHtmlElement]. Hmm, seems promising right? I then go on to try: var p = document.createElement('p'); var t = document.createTextNode('Insert Me'); p.appendChild(t); doc.appendChild(p); ...but nothing gets inserted. I've also tried the following replacements for doc: var doc = newHtmlLoader.window.opener.document.body; // .log(doc) -> [object HTMLBodyElement] var doc = newHtmlLoader.window.opener.document; // .log(doc) -> Error: HIERARCHY_REQUEST_ERR: DOM Exception 3 ...as well as the following with jQuery: $(doc).append('<p>Insert Me</p>'); // again, nothing So, anyone had any experience in accessing a NativeWindow's inner content programmatically? Any help will be greatly appreciated.

  • Why is this unwanted ">" character being displayed when displaying this PHP document in a browser?

    - by CT
    This page takes an asset id from $_GET of the url and displays some info about the asset after querying a mysql database. When I view the page in my browser there is an unwanted "" character within the page and I have no idea why. I've commented where it appears. It appears before the < table create tag right afterward. The < table tag was originally outside the php script section but I threw it in to see if it made a difference. It did not. Thank you all. I am viewing the page in Firefox.

  • Gotchas INSERTing into SQLite on Android?

    - by paul.meier
    Hi friends, I'm trying to set up a simple SQLite database in Android, handling the schema via a subclass of SQLiteOpenHelper. However, when I query my tables, the columns I think I've inserted are never present. Namely, in SQLiteOpenHelper's onCreate(SQLiteDatabase db) method, I use db.execSQL() to run CREATE TABLE commands, then have tried both db.execSQL and db.insert() to run INSERT commands on the tables I've just created. This appears to run fine, but when I try to query them I always get 0 rows returned (for debugging, the queries I'm running are simple SELECT * FROM table and checking the Cursor's getCount()). Anybody run into anything like this before? These commands seem to run on command-line sqlite3. Are they're gotchas that I'm missing (e.g. INSERTS must/must not be semicolon terminated, or some issue involving multiple tables)? I've attached some of the code below. Thanks for your time, and let me know if I can clarify further. @Override public void onCreate(SQLiteDatabase db) { db.execSQL("CREATE TABLE "+ LEVEL_TABLE +" (" + " "+ _ID +" INTEGER PRIMARY KEY AUTOINCREMENT," + " level TEXT NOT NULL,"+ " rows INTEGER NOT NULL,"+ " cols INTEGER NOT NULL);"); db.execSQL("CREATE TABLE "+ DYNAMICS_TABLE +" (" + " level_id INTEGER NOT NULL," + " row INTEGER NOT NULL,"+ " col INTEGER NOT NULL,"+ " type INTEGER NOT NULL);"); db.execSQL("CREATE TABLE "+ SCORE_TABLE +" (" + " level_id INTEGER NOT NULL," + " score INTEGER NOT NULL,"+ " date_achieved DATE NOT NULL,"+ " name TEXT NOT NULL);"); this.enterFirstLevel(db); } And a sample of the insert code I'm currently using, which gets called in enterFirstLevel() (some values hard-coded just to get it running...): private void insertDynamic(SQLiteDatabase db, int row, int col, int type) { ContentValues values = new ContentValues(); values.put("level_id", "1"); values.put("row", Integer.toString(row)); values.put("col", Integer.toString(col)); values.put("type", Integer.toString(type)); db.insertOrThrow(DYNAMICS_TABLE, "col", values); } Finally, query code looks like this: private Cursor fetchLevelDynamics(int id) { SQLiteDatabase db = this.leveldata.getReadableDatabase(); try { String fetchQuery = "SELECT * FROM " + DYNAMICS_TABLE; String[] queryArgs = new String[0]; Cursor cursor = db.rawQuery(fetchQuery, queryArgs); Activity activity = (Activity) this.context; activity.startManagingCursor(cursor); return cursor; } finally { db.close(); } }

  • get Phone numbers from android phone

    - by Luca
    Hi! First of all i'm sorry for my english... I've a problem getting phone numbers from contacts. That's my code import android.app.ListActivity; import android.database.Cursor; import android.os.Bundle; import android.provider.ContactsContract; import android.widget.SimpleAdapter; import android.widget.Toast; import java.util.ArrayList; import java.util.HashMap; public class TestContacts extends ListActivity { private ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>(); private SimpleAdapter numbers; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.contacts); numbers = new SimpleAdapter( this, list, R.layout.main_item_two_line_row, new String[] { "line1","line2" }, new int[] { R.id.text1, R.id.text2 } ); setListAdapter( numbers ); Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); while (cursor.moveToNext()) { String contactId = cursor.getString(cursor.getColumnIndex( ContactsContract.Contacts._ID)); String hasPhone = cursor.getString(cursor.getColumnIndex( ContactsContract.Contacts.HAS_PHONE_NUMBER)); //check if the contact has a phone number if (Boolean.parseBoolean(hasPhone)) { Cursor phones = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, null, null); while (phones.moveToNext()) { // Get the phone number!? String contactName = phones.getString( phones.getColumnIndex( ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); String phoneNumber = phones.getString( phones.getColumnIndex( ContactsContract.CommonDataKinds.Phone.NUMBER)); Toast.makeText(this, phoneNumber, Toast.LENGTH_LONG).show(); drawContact(contactName, phoneNumber); } phones.close(); } }cursor.close(); } private void drawContact(String name, String number){ HashMap<String,String> item = new HashMap<String,String>(); item.put( "line1",name); item.put( "line2",number); list.add( item ); numbers.notifyDataSetChanged(); } } It'seems that no contact have a phone number (i've added 2 contacts on the emulator and i've tried also on my HTC Desire). The problem is that if (Boolean.parseBoolean(hasPhone)) returns always false.. How can i get correctly phone numbers? I've tried to call drawContact(String name, String number) before the if statement without querying for the phone number, and it worked (it draws two times the name). but on the LinearLayout they are not ordered alphabetically... how can i order alphabetically (similar to the original contacts app)? thank you in advice, Luca

This is horrible. I've specified the identifierGenerator as "Auto". Please see the above code. As a sidenote, I was trying to debug and seeing how the objects are getting retrieved from the database. Looks like the enrollmentgroupmembership records have the tierweight value populated. However if I look at the tierweight object, it doesn't have the enrollmentgroupmembership records. I'm puzzled. I think these two problems must be related. Maddy.

  • Getting error "Association references unmapped class" when using interfaces in model

    - by Bjarke
    I'm trying to use the automap functionality in fluent to generate a DDL for the following model and program, but somehow I keep getting the error "Association references unmapped class: IRole" when I call the GenerateSchemaCreationScript method in NHibernate. When I replace the type of the ILists with the implementation of the interfaces (User and Role) everything works fine. What am I doing wrong here? How can I make fluent use the implemented versions of IUser and IRole as defined in Unity? public interface IRole { string Title { get; set; } IList<IUser> Users { get; set; } } public interface IUser { string Email { get; set; } IList<IRole> Roles { get; set; } } public class Role : IRole { public virtual string Title { get; set; } public virtual IList<IUser> Users { get; set; } } public class User : IUser { public virtual string Email { get; set; } public virtual IList<IRole> Roles { get; set; } } I use the following program to generate the DDL using the GenerateSchemaCreationScript in NHibernate: class Program { static void Main(string[] args) { var ddl = new NHibernateSessionManager(); ddl.BuildConfiguration(); } } public class NHibernateSessionManager { private ISessionFactory _sessionFactory; private static IUnityContainer _container; private static void InitContainer() { _container = new UnityContainer(); _container.RegisterType(typeof(IUser), typeof(User)); _container.RegisterType(typeof(IRole), typeof(Role)); } public ISessionFactory BuildConfiguration() { InitContainer(); return Fluently.Configure().Database(MsSqlConfiguration.MsSql2008 .ConnectionString("ConnectionString")) .Mappings(m => m.AutoMappings.Add( AutoMap.AssemblyOf<IUser>())) .ExposeConfiguration(BuildSchema) .BuildSessionFactory(); } private void BuildSchema(Configuration cfg) { var ddl = cfg.GenerateSchemaCreationScript(new NHibernate.Dialect.MsSql2008Dialect()); System.IO.File.WriteAllLines("Filename", ddl); } }

  • Rails has-and-belongs-to-many form question

    - by swilliams
    Sorry for the semi-generic title, but I'm still pretty new at rails and couldn't think of a succinct way to put the question. I have a basic habtm model setup: a Project has many Resources and a Resource can have many Projects. I have the database and models setup properly, and can do everything I need to via the console, but I'm having trouble translating it all into the view. On the show view for the Project, I want to be able to create a Resource and automatically assign it to the current Project. Here's my basic html: <p> <b>Name:</b> <%=h @project.name %> </p> <h2>Equipment</h2> <ul> <% @project.resources.each do |r| %> <li><%=h r.name %></li> <% end %> </ul> <h2>Add A Resource</h2> <% form_for(@project) do |f| %> <%= f.error_messages %> <p> Resource Name:<br /> <%= f.text_field :resources %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> Obviously, that form won't work, but I'm at a loss for what to do next. I've searched around for various examples, but haven't found one for what I'm trying to do here. One thing I've thought of was to change the form to be form_for(Resource.new) and include a hidden input of the @project.id. And then when the resource_controller handles the form, check for that id and go from there. That seems like an ugly kludge though.

  • Generating custom-form documents from base-form plus XML?

    - by KlaymenDK
    Hi all, this is my first stack overflow, and it's a complex one. Sorry. My task is to generate custom documents from a basic template plus some XML without having a custom form design element for each case. Here's the whole picture: We are building a Lotus Notes (client, not web) application for world-wide application access control; the scope is something like 400.000 users being able to request access to any of 1000+ applications. Each application needs its own request form -- different number of approvers, various info required, that sort of thing. We simply can't have a thousand forms in a database (one per application), and anyway their maintenance really needs to be pushed from the developers to the application owners. So instead of custom forms, we'd like to create a generic "template" form that stores a block of basic fields, but then allows application owners to define another block of fields dynamically -- "I want a mandatory plain-text field named 'Name' here, and then a date field named 'Due' here that must be later than today's date, and then ...". I hope this makes sense (if not, think of it as a generic questionnaire application). I pretty much have the structure in place for designing the dynamic fields (form builder GUI - XML-encoded data - pre-rendered DXL for injecting into a form), including mark-up for field types, value options, and rudimentary field validation instructions. My problem is generating a document with this dynamic content injected at the proper location (without needing a custom form design element for each case). Doing the dynamic content via HTML is out. The Notes client web rendering is simply way too poor, and it would be quite a challenge to implement things like field validation instructions, date selectors, and name look-ups. DXL, on the other hand, would allow us to use native Notes fields and code. As a tech demo, I've managed to implement a custom form generator that injects the pre-rendered DXL for the dynamic content into a base form; but as I said, we don't want a ton of custom form design elements. I've tried to implement a way to create a document with the "store form in document" flag set, but once I've created the document from the base form, I can't get DXL access to the stored form design, and so I can't inject my dynamic content. I know this is not something Notes was ever intended to do. Has anyone ever tried something like it (and gotten away with it)? Thanks for reading this far. With a boatload of thanks in advance, Jan Gundtofte-Bruun

  • How can I modify my classes to use it's collections in WPF TreeView

    - by Victor
    Hello, i'am trying to modify my objects to make hierarchical collection model. I need help. My objects are Good and GoodCategory: public class Good { int _ID; int _GoodCategory; string _GoodtName; public int ID { get { return _ID; } } public int GoodCategory { get { return _GoodCategory; } set { _GoodCategory = value; } } public string GoodName { get { return _GoodName; } set { _GoodName = value; } } public Good(IDataRecord record) { _ID = (int)record["ID"]; _GoodtCategory = (int)record["GoodCategory"]; } } public class GoodCategory { int _ID; string _CategoryName; public int ID { get { return _ID; } } public string CategoryName { get { return _CategoryName; } set { _CategoryName = value; } } public GoodCategory(IDataRecord record) { _ID = (int)record["ID"]; _CategoryName = (string)record["CategoryName"]; } } And I have two Collections of these objects: public class GoodsList : ObservableCollection<Good> { public GoodsList() { string goodQuery = @"SELECT `ID`, `ProductCategory`, `ProductName`, `ProductFullName` FROM `products`;"; using (MySqlConnection conn = ConnectToDatabase.OpenDatabase()) { if (conn != null) { MySqlCommand cmd = conn.CreateCommand(); cmd.CommandText = productQuery; MySqlDataReader rdr = cmd.ExecuteReader(); while (rdr.Read()) { Add(new Good(rdr)); } } } } } public class GoodCategoryList : ObservableCollection<GoodCategory> { public GoodCategoryList () { string goodQuery = @"SELECT `ID`, `CategoryName` FROM `product_categoryes`;"; using (MySqlConnection conn = ConnectToDatabase.OpenDatabase()) { if (conn != null) { MySqlCommand cmd = conn.CreateCommand(); cmd.CommandText = productQuery; MySqlDataReader rdr = cmd.ExecuteReader(); while (rdr.Read()) { Add(new GoodCategory(rdr)); } } } } } So I have two collections which takes data from the database. But I want to use thats collections in the WPF TreeView with HierarchicalDataTemplate. I saw many post's with examples of Hierarlichal Objects, but I steel don't know how to make my objects hierarchicaly. Please help.

  • Modular GWT design concerns

    - by GlGuru
    Hi, I have a couple of questions regarding a modular GWT based application framework. I have some ideas about them but being new to the field of web development I feel they are far from ideal. I'd appreciate a few comments and suggestions in this regard. Here are my questions: I am developing a framework which will allow third parties to embed GWT applications into our website and do some communication with them using simple iFrame postMessage. All these third party modules are going to use our SDK which is also GWT based. The problem arises that even though all the modules will be using the same codebase there is going to be a massive overheard in the amount of duplicate Javascript code (i.e. our common SDK code base which is quite large) being downloaded on the client's machine. This is highly redundant and problematic, not only due to the sheer size of duplicate code but, also due to the fact that subsequent updates of the SDK would require the modules to be recompiled which is going to create a DLL hell kind of scenario in the long run. What is the best way of doing this kind of thing? Is there a way where I can have some static GWT code (i.e. the SDK) and the dynamic GWT module refers to it (even if lies on a different domain) and it all work happily? The other part of the problem lies in providing robust scripting front end to the SDK. At first it appears to be trivial since Javascript itself is a scripting language. However, I do not know how to load and call a piece of pure Javascript code at runtime? I am willing to put restrictions on the target Javascript (i.e. having a function main and unique namespace or something). Furthermore the Javascript will come as a string from a database and not as a full URL. If its doable in Javascript how does one get this right in GWT i.e. forcing the compiler to emit a certain function in the generated Javascript? This I believe can be lesser of a problem by having a stub Javascript with all the right requirements which just loads up a GWT generated Javascript. Is any of this possible at all? I generally hate to be this verbose but I hope to find a quick solution to the problem as its holding up my progress. I'd highly appreciate any comments, suggestions and experiences.

  • List of checkboxes

    - by Andrea Girardi
    Hi all, Happy New Year to all. I'm a newbie in VB.NET and ASP.NET. This is my problem: I retrieve a list of records from DB and, for every row, I need to show 4 checkboxes. I can use a checkboxlist for every rows, but it's not so clear how I can process the results after the submit. I've some object and some operations available for that object. From database I extract a list of object with all operations. For every operation I want to show a check box to enable or disable the operation. The result is something like that: OBJ1 - url - [] [x] [] OBJ2 - url - [] [x] [x] On url I've an href to another page created using the Id retrieved from DB. To create that I used this code: <td class="column-filename"> <strong> <asp:Label runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "GroupName")%>'></asp:Label> </strong> </td> <td align="left"> <span style="vertical-align:middle"> <asp:CheckBoxList runat="server" ID="operations" RepeatDirection="Horizontal" RepeatLayout="Table"> <asp:ListItem Text="View"></asp:ListItem> <asp:ListItem Text="Upload"></asp:ListItem> <asp:ListItem Text="Move"></asp:ListItem> <asp:ListItem Text="Delete"></asp:ListItem> <asp:ListItem Text="Rename"></asp:ListItem> <asp:ListItem Text="Replace"></asp:ListItem> </asp:CheckBoxList> </span> </td> </asp> </asp> my problem is: how can I parse all checkboxes? could you help me or send me a link or any other resources to solve my issue? many thanks! Andrea
