  • PHP 5.2 Function needed for GENERIC sorting FOLLOWUP

    - by donbriggs
    OK, you guys gave me a great solution for sorting a recordset array last Friday. (http://stackoverflow.com/questions/2884325/php-5-2-function-needed-for-generic-sorting-of-a-recordset-array) But now when I implement it, I end up with an extra element in the recordset array. I won't wast space reposting the same info, as the link is above. But the bottom line is that when I sort an array of 5 records, the resulting array has 6 records. The last element in the array is not a record array, but rather just a element containing an integer value of 1. I presume that it is somehow getting the output value of the "strnatcasecmp" function, but I have no idea how it is happening. Here is the function that you fine folks provided last week: function getSortCommand($field, $sortfunc) { return create_function('$var1, $var2', 'return '.$sortfunc.'($var1["'.$field.'"], $var2["' .$field .'"]);'); } And here is the line I am calling to sort the array: $trek[] = usort($trek, getSortCommand('name', 'strnatcasecmp')); This produces the following output, with an extra element tacked on to the end. Array ( [0] = Array ( [name] = Kirk [shirt] = Gold [assign] = Bridge ) [1] => Array ( [name] => McCoy [shirt] => Blue [assign] => Sick Bay ) [2] => Array ( [name] => Scotty [shirt] => Red [assign] => Engineering ) [3] => Array ( [name] => Spock [shirt] => Blue [assign] => Bridge ) [4] => Array ( [name] => Uhura [shirt] => Red [assign] => Bridge ) [5] => 1 )

  • Any merit to a lazy-ish juxt function?

    - by NielsK
    In answering a question about a function that maps over multiple functions with the same arguments (A: juxt), I came up with a function that basically took the same form as juxt, but used map: (defn could-be-lazy-juxt [& funs] (fn [& args] (map #(apply %1 %2) funs (repeat args)))) => ((juxt inc dec str) 1) [2 0 "1"] => ((could-be-lazy-juxt inc dec str) 1) (2 0 "1") => ((juxt * / -) 6 2) [12 3 4] => ((could-be-lazy-juxt * / -) 6 2) (12 3 4) As posted in the original question, I have little clue about the laziness or performance of it, but timing in the REPL does suggest something lazy-ish is going on. => (time (apply (juxt + -) (range 1 100))) "Elapsed time: 0.097198 msecs" [4950 -4948] => (time (apply (could-be-lazy-juxt + -) (range 1 100))) "Elapsed time: 0.074558 msecs" (4950 -4948) => (time (apply (juxt + -) (range 10000000))) "Elapsed time: 1019.317913 msecs" [49999995000000 -49999995000000] => (time (apply (could-be-lazy-juxt + -) (range 10000000))) "Elapsed time: 0.070332 msecs" (49999995000000 -49999995000000) I'm sure this function is not really that quick (the print of the outcome 'feels' about as long in both). Doing a 'take x' on the function only limits the amount of functions evaluated, which probably is limited in it's applicability, and limiting the other parameters by 'take' should be just as lazy in normal juxt. Is this juxt really lazy ? Would a lazy juxt bring anything useful to the table, for instance as a compositing step between other lazy functions ? What are the performance (mem / cpu / object count / compilation) implications ? Is that why the Clojure juxt implementation is done with a reduce and returns a vector ? Edit: Somehow things can always be done simpler in Clojure. (defn could-be-lazy-juxt [& funs] (fn [& args] (map #(apply % args) funs)))

  • Remove pointer object whose reference is mantained in three different lists

    - by brainydexter
    I am not sure how to approach this problem: 'Player' class mantains a list of Bullet* objects: class Player { protected: std::list< Bullet* > m_pBullet_list; } When the player fires a Bullet, it is added to this list. Also, inside the constructor of bullet, a reference of the same object is updated in CollisionMgr, where CollisionMgr also mantains a list of Bullet*. Bullet::Bullet(GameGL*a_pGameGL, Player*a_pPlayer) : GameObject( a_pGameGL ) { m_pPlayer = a_pPlayer; m_pGameGL->GetCollisionMgr()->AddBullet(this); } class CollisionMgr { void AddBullet(Bullet* a_pBullet); protected: std::list< Bullet*> m_BulletPList; } In CollisionMgr.Update(); based on some conditions, I populate class Cell which again contain a list of Bullet*. Finally, certain conditions qualify a Bullet to be deleted. Now, these conditions are tested upon while iterating through a Cell's list. So, if I have to delete the Bullet object, from all these places, how should I do it so that there are no more dangling references to it? std::list< Bullet*>::iterator bullet_it; for( bullet_it = (a_pCell->m_BulletPList).begin(); bullet_it != (a_pCell->m_BulletPList).end(); bullet_it++) { bool l_Bullet_trash = false; Bullet* bullet1 = *bullet_it; // conditions would set this to true if ( l_Bullet_Trash ) // TrashBullet( bullet1 ); continue; } Also, I was reading about list::remove, and it mentions that it calls the destructor of the object we are trying to delete. Given this info, if I delete from one list, the object does not exist, but the list would still contain a reference to it..How do I handle all these problems ? Can someone please help me here ? Thanks PS: If you want me to post more code or provide explanation, please do let me know.

  • how to use a parameterized function for the Default Binding of a Sql Server column

    - by Walt Gaber
    I have a table that catalogs selected files from multiple sources. I want to record whether a file is a duplicate of a previously cataloged file at the time the new file is cataloged. I have a column in my table (“primary_duplicate”) to record each entry as ‘P’ (primary) or ‘D’ (duplicate). I would like to provide a Default Binding for this column that would check for other occurrences of this file (i.e. name, length, timestamp) at the time the new file is being recorded. I have created a function that performs this check (see “GetPrimaryDuplicate” below). But I don’t know how to bind this function which requires three parameters to the table’s “primary_duplicate” column as its Default Binding. I would like to avoid using a trigger. I currently have a stored procedure used to insert new records that performs this check. But I would like to ensure that the flag is set correctly if an insert is performed outside of this stored procedure. How can I call this function with values from the row that is being inserted? USE [MyDatabase] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[FileCatalog]( [id] [uniqueidentifier] NOT NULL, [catalog_timestamp] [datetime] NOT NULL, [primary_duplicate] nchar NOT NULL, [name] nvarchar NULL, [length] [bigint] NULL, [timestamp] [datetime] NULL ) ON [PRIMARY] GO ALTER TABLE [dbo].[FileCatalog] ADD CONSTRAINT [DF_FileCatalog_id] DEFAULT (newid()) FOR [id] GO ALTER TABLE [dbo].[FileCatalog] ADD CONSTRAINT [DF_FileCatalog_catalog_timestamp] DEFAULT (getdate()) FOR [catalog_timestamp] GO ALTER TABLE [dbo].[FileCatalog] ADD CONSTRAINT [DF_FileCatalog_primary_duplicate] DEFAULT (N'GetPrimaryDuplicate(name, length, timestamp)') FOR [primary_duplicate] GO USE [MyDatabase] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE FUNCTION [dbo].[GetPrimaryDuplicate] ( @name nvarchar(255), @length bigint, @timestamp datetime ) RETURNS nchar(1) AS BEGIN DECLARE @c int SELECT @c = COUNT(*) FROM FileCatalog WHERE name=@name and length=@length and timestamp=@timestamp and primary_duplicate = 'P' IF @c > 0 RETURN 'D' -- Duplicate RETURN 'P' -- Primary END GO

  • Reduce function calls

    - by Curious2learn
    Hello, I profiled my python program and found that the following function was taking too long to run. Perhaps, I can use a different algorithm and make it run faster. However, I have read that I can also possibly increase the speed by reducing function calls, especially when it gets called repeatedly within a loop. I am a python newbie and would like to learn how to do this and see how much faster it can get. Currently, the function is: def potentialActualBuyers(setOfPeople,theCar,price): count=0 for person in setOfPeople: if person.getUtility(theCar) >= price and person.periodCarPurchased==None: count += 1 return count where setOfPeople is a list of person objects. I tried the following: def potentialActualBuyers(setOfPeople,theCar,price): count=0 Utility=person.getUtility for person in setOfPeople: if Utility(theCar) >= price and person.periodCarPurchased==None: count += 1 return count This, however, gives me an error saying local variable 'person' referenced before assignment Any suggestions, how I can reduce function calls or any other changes that can make the code faster. Again, I am a python newbie and even though I may possibly be able to use a better algorithm, it is still worthwhile learning the answer to the above question. Thanks very much.

  • Function in JS returns undefined

    Hello there, I have the following problem. The alert allways returns undefined, but I know it has a value. What am I doing wrong. I'm out of solutions... I'm using JQUERY jquery-1.4.2.min.js Tnx in advance $(document).ready(function(){ $('#generateButton').click(createIBAN); }); function createIBAN(){ //---- First check if a bank has been selected, //---- if not, then show error if($('#selectBank').val()==''){ alert('Selecte a bank!'); }else{ var bankAccount = generateBankAccount(); alert(bankAccount); } return false; } function generateBankAccount(){ //---- Create "elfproef" bankaccount var bankAccount = ''; //---- Set the amount of digits in a bankaccount digitAmount = 9; //---- Make random digitstring for (var i = 0; i < digitAmount; i++) { bankAccount += Math.floor(Math.random() * digitAmount); } //---- validate the string, if not "elf-proef" if (elfProef(bankAccount)==false) { //---- regenerate the string generateBankAccount(); }else{ return bankAccount; } } function elfProef(bankAccount) { //---- set sum to 0 and start the for-loop for counting var sum = 0; for (var i = 0; i < digitAmount; i++) { //---- for every digit multiply it times 9 - number //---- of the digit and count it to the sum var sum += bankAccount.charAt(i) * (digitAmount - i); } //---- Check if sum can be devided by 11 without having ##,## if(sum % 11==0){ //---- return true means string is "elf-proef" return true; }else { //---- String is not "elf-proef", try again return false; } }

  • Returning c_str from a function

    - by user199421
    This is from a small library that I found online: const char* GetHandStateBrief(const PostFlopState* state) { static std::ostringstream out; ... rest of the function ... return out.str().c_str() Now in my code I am doing this: const char *d = GetHandStateBrief(&post); std::cout<< d << std::endl; Now, at first d contained garbage. I then realized that the c string I am getting from the function is destroyed when the function returns because std::ostringstream is allocated on the stack. So I added: return strdup( out.str().c_str()); And now I can get the text I need from the function. I have two questions: 1) Am I understanding this correctly? 2) I later noticed that the ostringstream was was allocated with static storage. Doesn't that mean that the object is supposed to stay in memory until the program terminates? and if so , then why can't I access the string?

  • javascript: "Object doesn't support this property or method" when ActiveX object called.

    - by agnieszka
    I've got simple html on Login.aspx with an ActiveX object: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head><title></title> <script language="javaScript" type="text/javascript"> function getUserInfo() { var userInfo = MyActiveX.GetInfo(); form1.info.value = userInfo; form1.submit(); } </script> </head> <body onload="javascript:getUserInfo()"> <object id="MyActiveX" name="MyActiveX" codebase="MyActiveX.cab" classid="CLSID:C63E6630-047E-4C31-H457-425C8412JAI25"></object> <form name="form1" method="post" action="Login.aspx"> <input type="hidden" id="info" name="info" value="" /> </form> </body> </html> The code works perfectly fine on my machine (edit: hosted and run), it does't work on the other: there is an error "Object doesn't support this property or method" in the first line of javascript function. The cab file is in the same folder as the page file. I don't know javascript at all and have no idea why is the problem occuring. Googling didn't help. Do you ave any idea? Edit: on both machines IE was used and activex was enabled. Edit2: I also added if (document.MyActiveX) at the beggining of the function and I still get error in the same line of code - I mean it looks like document.MyActiveX is true but calling the method still fails

  • How do I add code automatically to a derived function in C++

    - by Ian
    I have code that's meant to manage operations on both a networked client and a server, since there is significant overlap between the two. However, there are a few functions here and there that are meant to be exclusively called by the client or server, and accidentally calling a client function on the server (or vice versa) is a significant source of bugs. To reduce these sorts of programming errors, I'm trying to tag functions so that they'll raise a ruckus if they're misused. My current solution is a simple macro at the start of each function that calls an assert if the client or server accesses members they shouldn't. However, this runs into problems when there are multiple derived instances of classes, in that I have to tag the implementation as client or server side in EVERY child class. What I'd like to be able to do is put a tag in the virtual member's signature in the base class, so that I only have to tag it once and not run into errors by forgetting to do it repeatedly. I've considered putting a check in a base class implementation and then referring to it with something like base::functionName, but that runs into the same issue as far as needing to manually add the function call to every implementation. Ideally, I'd be able to have parent versions of the function called automatically like default constructors do. Does anybody know how to achieve something like this in C++? Is there an alternate approach I should be considering? Thanks!

  • How to report progress of a JavaScript function?

    - by LambyPie
    I have a JavaScript function which is quite long and performs a number of tasks, I would like to report progress to the user by updating the contents of a SPAN element with a message as I go. I tried adding document.getElementById('spnProgress').innerText = ... statements throughout the function code. However, whilst the function is executing the UI will not update and so you only ever see the last message written to the SPAN which is not very helpful. My current solution is to break the task up into a number of functions, at the end of each I set the SPAN message and then "trigger" the next one with a window.setTimeout call with a very short delay (say 10ms). This yields control and allows the browser to repaint the SPAN with the updated message before starting the next step. However I find this very messy and difficult to follow the code, I'm thinking there must be a better way. Does anyone have any suggestions? Is there any way to force the SPAN to repaint without having to leave the context of the function? Thanks

  • Drupal theme preprocess function - primary links and suckerfish menus

    - by slimcady
    I have a preprocess function that works fine when the menu is single level list. However I would like it to work w/ suckerfish menus. I want to add a class to the top level menu item so that I can style it. This is the code I used for the single level menu: function cti_flex_preprocess_page(&$vars, $hook) { // Make a shortcut for the primary links variables $primary_links = $vars['primary_links']; // Loop thru the menu, adding a new class for CSS selectors $i = 1; foreach ($primary_links as $link => $attributes){ // Append the new class to existing classes for each menu item $class = $attributes['attributes']['class'] . " item-$i"; // Add revised classes back to the primary links temp variable $primary_links[$link]['attributes']['class'] = $class; $link['title'] = '<span class="hide">' . check_plain($link['title']) . '</span>'; $i++; } // end the foreach loop // reset the variable to contain the new markup $vars['primary_links'] = $primary_links; } I've been trying to use the menu_tree() function to no avail, for example: function cti_flex_preprocess_page(&$vars, $hook) { // Make a shortcut for the primary links variables $primary_links = $vars['primary_links']; // Loop thru the menu, adding a new class for CSS selectors $i = 1; foreach ($primary_links as $link => $attributes){ // Append the new class to existing classes for each menu item $class = $attributes['attributes']['class'] .

  • jQuery.ajax() + empty JSON object = parse error

    - by roosteronacid
    I get a parse error when using jQuery to load some JSON data. Here's a snippet of my code: jQuery.ajax({ dataType: "json", success: function (json) { jQuery.each(json, function () { alert(this["columnName"]); }); } }); I get no errors when parsing a non-empty JSON object. So my guess is that the problem is with my serializer. Question is: how do I format an empty JSON object which jQuery won't consider malformed? This is what I've tried so far, with no success: {[]} {[null]} {} {null} {"rows": []} {"rows": null} {"rows": {}} UPDATE: I can understand that I've been somewhat vague--let me try and clarify: Parsing of the JSON object is not the issue here--JQuery is - I think. jQuery throws a parse-error (invokes the error function). It seems like jQuery's internal JSON validation is not accepting any of the before mentioned objects. Not even the valid ones. Output of the error function is: XMLHttpRequest: XMLHttpRequest readyState=4 status=200 textStatus: parsererror errorThrown: undefined This goes for all of the before mentioned objects.

  • Connecting to an RMI object without registry

    - by Mark Probst
    I think I need to connect to a remote RMI object without going through the registry, but I don't know how. My situation is this: I'm implementing a simple job distribution service which consists of one distributor and multiple workers. The distributor has a registered RMI object to which clients connect to send jobs, and workers connect to accept jobs. Unfortunately the distributor and worker hosts are behind a firewall. To get to the distributor host I am tunneling two ports (one for the registry, one for the distributor object) via SSH, so I can get to the registry and the distributor from outside the firewall. To make that work I have to set "-Djava.rmi.server.hostname=localhost" on the distributor JVM so that the clients connect to their local, tunneled port, instead of the port on the actual distributor host, which is blocked. This creates a problem for the workers, though, because they need to connect to the distributor directly, but because of the "localhost" redirection they behave like clients and try to connect to a port on their own host, which is not available, because I'm not tunneling on the workers (it is impractical). Now, if I could connect to a remote object directly by giving the hostname and port, I could do away both with the registry on the distributor and the "localhost" hack, and make the workers connect properly. How do I do that? Or is there a different solution to this problem?

  • accessing private variable from member function in PHP

    - by Carson Myers
    I have derived a class from Exception, basically like so: class MyException extends Exception { private $_type; public function type() { return $this->_type; //line 74 } public function __toString() { include "sometemplate.php"; return ""; } } Then, I derived from MyException like so: class SpecialException extends MyException { private $_type = "superspecial"; } If I throw new SpecialException("bla") from a function, catch it, and go echo $e, then the __toString function should load a template, display that, and then not actually return anything to echo. This is basically what's in the template file <div class="<?php echo $this->type(); ?>class"> <p> <?php echo $this->message; ?> </p> </div> in my mind, this should definitely work. However, I get the following error when an exception is thrown and I try to display it: Fatal error: Cannot access private property SpecialException::$_type in C:\path\to\exceptions.php on line 74 Can anyone explain why I am breaking the rules here? Am I doing something horribly witty with this code? Is there a much more idiomatic way to handle this situation? The point of the $_type variable is (as shown) that I want a different div class to be used depending on the type of exception caught.

  • Best way to transfer an Entity Framework object over the web and back via JSON

    - by AVH
    I've got some MVC code that serializes an EF 3.5 object into an anonymous type for return as a JSON result to an AJAX call on my page. The hurdle I have is that when I send the object back to the server via JSON, (and let the ModelBinder deserialize it for me into my EF type), I have to update it in my Entity Framework context manually. Or at least that's what I'm doing now. It has no EntityKey, so attaching it fails. I end up having to look up the old object and update it property by property. Any ideas around this? Is the solution to pass the EntityKey around with my object? Here's what I have: public void Update(Album album) { using (var db = new BandSitesMasterEntities()) { var albumToUpdate = db.Album.First(x => x.ID == album.ID); albumToUpdate.AlbumTitle = album.AlbumTitle; albumToUpdate.Description = album.Description; albumToUpdate.ReleaseYear = album.ReleaseYear; albumToUpdate.ImageURL = album.ImageURL; albumToUpdate.OtherURL = album.OtherURL; db.SaveChanges(); } } And here's what I'd like to do, or something similar: public void Update(Album album) { using (var db = new BandSitesMasterEntities()) { db.Attach(album) db.SaveChanges(); } }

  • Where to define a filter function for a form field in my Joomla component's preferences

    - by Herman
    I am creating a component in Joomla 2.5. This component has some options that are defined in its config.xml, so they can be set in the preferences of the component. Now I would like to apply a filter to one of these option fields, using the attribute filter="my_filter". In the source code of JForm I saw the following lines at the very end of the implementation of JForm::filterField(): if (strpos($filter, '::') !== false && is_callable(explode('::', $filter))) { $return = call_user_func(explode('::', $filter), $value); } elseif (function_exists($filter)) { $return = call_user_func($filter, $value); } That's what I needed for using a filter function defined by myself! I managed to do this for form fields used in the views of my component. I defined the filter function as MyComponentHelper::my_filter(), where MyComponentHelper is a helper class which I always load in the very base of my component. And in the form's xml I added filter="MyComponentHelper::my_filter" to the fields that have to be filtered. However... when I am trying to apply the filter function to a form field in my component's preferences, I am not in my own component, but in com_config instead, so my helper class is not available! So, therefore, my question: where to define my own filter function in such a way that it can be found and called by JForm::filterField() in com_config?? Help is very much appreciated.

  • Javascript "Match" Function Not Returning Proper Results in Safari or IE (but yes in FF)

    - by Jascha
    Forgive me as this is a time sensitive issue and I will have to switch the site back in a few hours so the link will be bad... but: I am simply comparing two strings looking for a match with this function... I have an array of objects called linkArray and I need to match the .src of each object to a .src I send it (the src of the clicked image). if the the src of the image I clicked matches the src of an object in my array, I set a variable to the link string of that object and return true, letting my page know that the link is available. Now, this works great in FF. But not in any other browser and I can't figure out for the life of me why. I have set up a dialogue box to literally compare, by eye, the two strings that should at the very least throw the message "match". Can anyone see what I am missing here??? here is the link... http://7thart.com/Jewish-History-and-Culture/Jews-and-Baseball-An-American-Love-Story If you click any of the thumbnails on the left, you will activate the function. Again, I apologize as after a few hours I have to switch back to the original site and this link will be invalid. Thanks in advance for your help. (function below)... function matchLink(a){ for(var i=0;i<linkArray.length;i++){ var fixLink = '../' + linkArray[i]['src']; alert(fixLink + '\n = \n' + a); if(fixLink == a){ alert('match'); newLink = linkArray[i]['link']; return true; } } return false; } Note: The "match" will return on two of the images.. the initial image, and the first thumbnail on the left. The second thumbnail SHOULD match, and the third one SHOULD NOT match.

  • WCF: Exposed Object Model - stuck in a loop

    - by Mark
    Hi I'm working on a pretty big WSSF project. I have a normal object model in the business layer. Eg a customer has an orders collection property, when this is accessed then it loads from the data layer (lazy loading). An order has a productCollection property etc etc.. Now the bit I'm finding tricky is exposing this via WCF. I want to export a collection of orders. The client app will also need information about the customers. Using the WSSF data contract designer I have set it up so that customers have a property called "order collection". This is fine if you have a customer object and would like to look at the orders but if you have an order object there is no customer property so it doesn't work going up the hierarchy. I've tried adding a customer property to the orders object but then the code gets stuck in a loop when it loads the data contracts up. This is because it doesn't load on demand like in the business layer. I need to load all properties up before the objects can be sent out via WCF. It ends up loading an order, then the customer for that order, then the orders for that customer, then the customer for that order etc etc... I'm sure I've got all this wrong. Help!!

  • How to print each object in a collection in a separate page in Silverlight

    - by Ash
    I would like to know if its possible to print each object in a collection in separate pages using Silverlight printing API. Suppose I have a class Label public class Label { public string Address { get; set; } public string Country { get; set; } public string Name { get; set; } public string Town { get; set; } } I can use print API and print like this. private PrintDocument pd; private void PrintButton_Click(object sender, RoutedEventArgs e) { pd.Print("Test Print"); } private void pd_PrintPage(object sender, PrintPageEventArgs e) { Label labelToPrint = new Label() { Name = "Fake Name", Address = "Fake Address", Country = "Fake Country", Town = "Town" }; var printpage = new LabelPrint(); printpage.DataContext = new LabelPrintViewModel(labelToPrint); e.PageVisual = printpage; } LabelPrint Xaml <StackPanel x:Name="LayoutRoot" VerticalAlignment="Center" HorizontalAlignment="Center"> <TextBlock Text="{Binding Name}" /> <TextBlock Text="{Binding Address}" /> <TextBlock Text="{Binding Town}" /> <TextBlock Text="{Binding Country}" /> </StackPanel> Now, say I've a collection of Label objects, List<Label> labels = new List<Label>() { labelToPrint, labelToPrint, labelToPrint, labelToPrint }; How can I print each object in the list in separate pages ? Thanks for any suggestions ..

  • Semi-generic function

    - by Fredrik Ullner
    I have a bunch of overloaded functions that operate on certain data types such as int, double and strings. Most of these functions perform the same action, where only a specific set of data types are allowed. That means I cannot create a simple generic template function as I lose type safety (and potentially incurring a run-time problem for validation within the function). Is it possible to create a "semi-generic compile time type safe function"? If so, how? If not, is this something that will come up in C++0x? An (non-valid) idea; template <typename T, restrict: int, std::string > void foo(T bar); ... foo((int)0); // OK foo((std::string)"foobar"); // OK foo((double)0.0); // Compile Error Note: I realize I could create a class that has overloaded constructors and assignment operators and pass a variable of that class instead to the function.
