  • drupal's hook_preprocess_page not working as expected

    - by Peter Carrero
    i am having an issue where hook_preprocess_page 's changes to &$variables is not being rendered, even though it is the last item under $theme_registry['page']['preprocess functions']. logging contents of $variables to a file show the contents changed, but contents appear unchanged on the site. flushed all cache on drupal, flushed all browser caches and still the same result. /** * Implementation of hook_preprocess_page(). */ function grinchlist_preprocess_page(&$variables) { if (grinchlist_usercheck($variables['user']['uid'])) { $variables['scripts'] = preg_replace('/<script[^>]*christmas_snow.*<\/script>/','',$variables['scripts']); } file_put_contents('/tmp/vars.txt',print_r($variables,true)); } the /tmp/vars.txt shows the variables properly, but the browser still show the script being loaded. this may be a silly example, but i've had this issue with the hook_preprocess_page in other instances and it would really help out to understand what is going on here... thanks.

  • Newbie Question: Read and Process a List of Text Files

    - by johnv
    I'm completely new to .NET and am trying as a first step to write a text processing program. The task is simple: I have a list of 10,000 text files stored in one folder, and I'm trying to read each one, store it as a string variable, then run it through a series of functions, then save the final output to another folder. So far I can only manage to manually input the file path like this (in VB.NET): Dim tRead As System.IO.StreamReader Public Function ReadFile() As String Dim EntireFile As String tRead = File.OpenText("c:\textexample\00001.txt") EntireFile = tRead.ReadToEnd Return EntireFile End Function Public Function Step1() ..... End Function Public Function Step2() ..... End Function .............. I'm wondering, therefore, if there's a way to automate this process. Perhaps for example store all input file path into a text file then read each entry at a time, then save the final output into the save path, again listed in a text file. Any help is greatly appreciated. ReplyQuote

  • XmlSerializer Performance Issue when Specifying XmlRootAttribute

    - by Dougc
    I'm currently having a really weird issue and I can't seem to figure out how to resolve it. I've got a fairly complex type which I'm trying to serialize using the XmlSerializer class. This actually functions fine and the type serializes properly, but seems to take a very long time in doing so; around 5 seconds depending on the data in the object. After a bit of profiling I've narrowed the issue down - bizarrely - to specifying an XmlRootAttribute when calling XmlSerializer.Serialize. I do this to change the name of a collection being serialized from ArrayOf to something a bit more meaningful. Once I remove the parameter the operation is almost instant! Any thoughts or suggestions would be excellent as I'm entirely stumped on this one!

  • SEARCHING AND REPLACING BRACKETS IN A STRING IN ORACLE 10G

    - by Tunde
    hello, Thanks as usual for your prompt and kind suggestions. i am currently developing a function that is meant to execute dynamically created SQL statements. this is done by concatenating the columns and fetching them via cursors. the problem is that when there is a function with a comma between its arguments, the concat concatenates the contents of the functions inclusive. Is it possible to skip contents of every bracket found in a string using REGEXP_SUBTR or REGEXP_REPLACE? Many thanks for the anticipated response.

  • need some jquery if-else statement help

    - by zeemy23
    Hello, the code below is broken, but I'm not sure how. I've definitely made some big assumptions here as a newbie. I'm basically trying to create an if else where imBannerRotater functions on #cast if the variable is true and #pram if it is false. How could I fix this to get that result? The # are URLs. Thanks!-zeem $(document).ready(function(){ if (mmjsRegionName == 'CO') { $("#cast").imBannerRotater({ return_type: 'json', data_map: { image_name: 'name', url_name: 'url' }, image_url: '#', base_path: '#', }); } else { $("#pram").imBannerRotater({ return_type: 'json', data_map: { image_name: 'name', url_name: 'url' }, image_url: '#', base_path: '#', }); });

  • Simplest way to flatten document to a view in RavenDB

    - by degorolls
    Given the following classes: public class Lookup { public string Code { get; set; } public string Name { get; set; } } public class DocA { public string Id { get; set; } public string Name { get; set; } public Lookup Currency { get; set; } } public class ViewA // Simply a flattened version of the doc { public string Id { get; set; } public string Name { get; set; } public string CurrencyName { get; set; } // View just gets the name of the currency } I can create an index that allows client to query the view as follows: public class A_View : AbstractIndexCreationTask<DocA, ViewA> { public A_View() { Map = docs => from doc in docs select new ViewA { Id = doc.Id, Name = doc.Name, CurrencyName = doc.Currency.Name }; Reduce = results => from result in results group on new ViewA { Id = result.Id, Name = result.Name, CurrencyName = result.CurrencyName } into g select new ViewA { Id = g.Key.Id, Name = g.Key.Name, CurrencyName = g.Key.CurrencyName }; } } This certainly works and produces the desired result of a view with the data transformed to the structure required at the client application. However, it is unworkably verbose, will be a maintenance nightmare and is probably fairly inefficient with all the redundant object construction. Is there a simpler way of creating an index with the required structure (ViewA) given a collection of documents (DocA)? FURTHER INFORMATION The issue appears to be that in order to have the index hold the data in the transformed structure (ViewA), we have to do a Reduce. It appears that a Reduce must have both a GROUP ON and a SELECT in order to work as expected so the following are not valid: INVALID REDUCE CLAUSE 1: Reduce = results => from result in results group on new ViewA { Id = result.Id, Name = result.Name, CurrencyName = result.CurrencyName } into g select g.Key; This produces: System.InvalidOperationException: Variable initializer select must have a lambda expression with an object create expression Clearly we need to have the 'select new'. INVALID REDUCE CLAUSE 2: Reduce = results => from result in results select new ViewA { Id = result.Id, Name = result.Name, CurrencyName = result.CurrencyName }; This prduces: System.InvalidCastException: Unable to cast object of type 'ICSharpCode.NRefactory.Ast.IdentifierExpression' to type 'ICSharpCode.NRefactory.Ast.InvocationExpression'. Clearly, we also need to have the 'group on new'. Thanks for any assistance you can provide. (Note: removing the type (ViewA) from the constructor calls has no effect on the above)

  • Flex - How do I get the absolute X and Y coordinate including HTML offset?

    - by Mauricio
    Hey everyone, I am calling a JS function through the ExternalInterface using Flex which requires the absolute X and Y coordinates to create a pop-up menu. The Flex application is displayed on the center of an HTML page, therefore there is an HTML X and Y offset to consider. I have tried using the LocalToGlobal and ContentToGlobal functions, but these are just giving me the X and Y coordinates relative to the Flex application, it is not considering the HTML X and Y offset of having the Flex app in the center of the page or varying different screen resolutions. Is the best approach to retrieve the HTML X and Y offset using JavaScript? Is there a Flex function I can use that provides the absolute X and Y coordinates based on the HTML page? Thanks!

  • How should I do custom sort in Python 3?

    - by S.Mark
    In Python 2.x, I could pass custom function to sorted and .sort functions >>> x=['kar','htar','har','ar'] >>> >>> sorted(x) ['ar', 'har', 'htar', 'kar'] >>> >>> sorted(x,cmp=customsort) ['kar', 'htar', 'har', 'ar'] Because, in My language, consonents are comes with this order "k","kh",....,"ht",..."h",...,"a" But In Python 3.x, looks like I could not pass cmp keyword >>> sorted(x,cmp=customsort) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'cmp' is an invalid keyword argument for this function Is there any alternatives or should I write my own sorted function too?

  • Marionette multi user/roles application

    - by Fabrizio Fortino
    I have to build a pretty complex application using Backbone Marionette. The user interface has to handle multiple users with different roles. For example the 'admin' user will see the complete menu whereas the 'guest' user will access a subset of the same menu. Moreover some views will be accessible to all the users but the functions inside them (add, edit, delete) need to be profiled on the different roles. I am not sure about the right approach to use in order to solve this issue. I could have different templates for the different roles but in this case plenty of code will be duplicated inside them. Is there any best practice (or maybe some example) to sort my problem out using Marionette? Thanks in advance, Fabrizio

  • spl_object_hash for PHP < 5.2 (unique ID for object instances)

    - by Rowan
    I'm trying to get unique IDs for object instances in PHP 5+. The function, spl_object_hash() is available from PHP 5.2 but I'm wondering if there's a workaround for older versions. There are a couple of functions in the comments on php.net but they're not working for me. The first (simplified): function spl_object_hash($object){ if (is_object($object)){ return md5((string)$object); } return null; } does not work with native objects (such as DOMDocument), and the second: function spl_object_hash($object){ if (is_object($object)){ ob_start(); var_dump($object); $dump = ob_get_contents(); ob_end_clean(); if (preg_match('/^object\(([a-z0-9_]+)\)\#(\d)+/i', $dump, $match)) { return md5($match[1] . $match[2]); } } return null; } looks like it could be a major performance buster! Does anybody have anything up their sleeve?

  • How to redirect output away from /dev/null

    - by Gowtham
    I have an application that runs the a command as below: <command> >& /dev/null I have no control on this. All the o/p generated by this command goes to /dev/null. I want the output to be visible on screen or redirected to a log file. I tried to use freopen() and related functions to reopen /dev/null to another file, but could not get it working. Do you have any other ideas? Is this possible at all? Thanks for your time. PS: I am working on Linux. -Gowtham

  • netbeans custom jax-ws stubs..

    - by Sam
    Hi, I am using netbeans 6.9. I have made a JAX-WS service that returns a complex type, I have also made a JAX-WS client to consume it. The JAX-WS system automaticly creates a class for the client, inferred from the WSDl spec. I want to make my own class for this using JAXB annotations, so that I can add some extra functions to it. How do I go about replacing the autogenerated file with my own one? Could I also use the same class in the service to control how it is transmitted? Thanks!

  • Need to make sure value is within 0-255

    - by igor
    This is probably really easy, but I'm lost on how to "make sure" it is in this range.. So basically we have class Color and many functions to implement from it. this function I need is: Effects: corrects a color value to be within 0-255 inclusive. If value is outside this range, adjusts to either 0 or 255, whichever is closer. This is what I have so far: static int correctValue(int value) { if(value<0) value=0; if(value>255) value=255; } Sorry for such a simple question ;/

  • Generating unobtrusive JS

    - by nico
    I have read quite a bit about unobtrusive JS and how to generate it and all that jazz... My problem is this: I have a website that heavily relies on mod_rewrite, so essentially all the pages requests are sent to index.php that generates the main structure of the page and then includes the appropriate page. Now, there are different sections in the site and each section uses different Javascript functions (e.g. for different AJAX requests). Now, if I just were to attach a function to the onload of the page obviously the thing would not work, as I do not have to initialise the same things for each page... so what is the best way to handle this situation? I hope the situation is clear, I'll be happy to clarify if needed

  • Minimalistic PHP template engine with caching but not Smarty?

    - by Pekka
    There are loads of questions for "the right" PHP template engine, but none of them is focused on caching. Does anybody know a lightweight, high-quality, PHP 5 based template engine that does the following out of the box: Low-level templating functions (Replacements, loops, and filtering, maybe conditionals) Caching of the parsed results with the possibility to set an individual TTL per item, and of course to force a reload programmatically Extremely easy usage (like Smarty's) Modest in polluting the namespace (the ideal solution would be one class to interact with from the outside application) But not Smarty. I have nothing against, and often use, Smarty, but I am looking for something a bit simpler and leaner. I took a look at Fabien Potencier's Twig that looks very nice and compiles templates into PHP code, but it doesn't do any actual caching beyond that. I need and want a template engine, as I need to completely separate code and presentation in a way that a HTML designer can understand later on, so please no fundamental discussions about whether template engines in PHP make sense. Those discussions are important, but they already exist on SO.

  • Arrow operator (->) usage in C

    - by Mohit Deshpande
    I am currently learning C by reading a good beginner's book called "Teach Yourself C in 21 Days" (I have already learned Java and C# so I am moving at a much faster pace). I was reading the chapter on pointers and the - (arrow) operator came up without explanation. I think that it is used to call members and functions (like the equivalent of the . (dot) operator, but for pointers instead of members). But I am not entirely sure. Could I please get an explanation and a code sample?

  • How to determine position (x,y) relative to the page of every character inside spans through javascript?

    - by Fernando
    This is as simple as I can get. I will have several spans randomly positioned on the screen through something like: $(".hidden:first").css('-webkit-transform','rotate('+((0.5-Math.random())*40)+'deg)'); $(".hidden:first").animate({ left: '+=' + (((screen.width-800-224)/2) + Math.random()*800), top: '+=' + (50+Math.random()*600) } [...] and later on I would like to iterate through every char of every of those elements (that are randomly position and have random rotation), and I would need to discover the (x,y) position of every character on the screen so I can colorize it, forming certain draws according to certain functions. Is this easily achievable? I am really inexperienced at javascript. Thanks. Fernando.

  • When is a scala partial function not a partial function?

    - by Fred Haslam
    While creating a map of String to partial functions I ran into unexpected behavior. When I create a partial function as a map element it works fine. When I allocate to a val it invokes instead. Trying to invoke the check generates an error. Is this expected? Am I doing something dumb? Comment out the check() to see the invocation. I am using scala 2.7.7 def PartialFunctionProblem() = { def dream()() = { println("~Dream~"); new Exception().printStackTrace() } val map = scala.collection.mutable.HashMap[String,()=>Unit]() map("dream") = dream() // partial function map("dream")() // invokes as expected val check = dream() // unexpected invocation check() // error: check of type Unit does not take parameters }

  • Pros and Cons of Different macro function / inline methods in C

    - by Robert S. Barnes
    According to the C FAQ, there are basically 3 practical methods for "inlining" code in C: #define MACRO(arg1, arg2) do { \ /* declarations */ \ stmt1; \ stmt2; \ /* ... */ \ } while(0) /* (no trailing ; ) */ or #define FUNC(arg1, arg2) (expr1, expr2, expr3) To clarify this one, the arguments are used in the expressions, and the comma operator returns the value of the last expression. or using the inline declaration which is supported as an extension to gcc and in the c99 standard. The do { ... } while (0) method is widely used in the Linux kernel, but I haven't encountered the other two methods very often if at all. I'm referring specifically to multi-statement "functions", not single statement ones like MAX or MIN. What are the pros and cons of each method, and why would you choose one over the other in various situations?

  • Equivalence Classes

    - by orcik
    I need to write a program for equivalence classes and get this outputs... (equiv '((a b) (a c) (d e) (e f) (c g) (g h))) => ((a b c g h) (d e f)) (equiv '((a b) (c d) (e f) (f g) (a e))) => ((a b e f g) (c d)) Basically, A set is a list in which the order doesn't matter, but elements don't appear more than once. The function should accept a list of pairs (elements which are related according to some equivalence relation), and return a set of equivalence classes without using iteration or assignment statements (e.g. do, set!, etc.). However, set utilities such as set-intersection, set-union and a function which eliminates duplicates in a list and built-in functions union, intersection, and remove-duplicates are allowed. Thanks a lot! By the way, It's not a homework question. A friend of mine need this piece of code to solve smilar questions.

  • I need a program to store the database script for oracle

    - by Hakan Kara
    We are developing a project that has 3 enviroments (development, test, production) So there are 3 databases (actually more than 3, because we have 5 customers so we have more than 10 databases) and they must be synchronised. There are 30 coders working for this project. Everone adds, deletes, and changes procedures, table columns etc. We need a program to store our database scripts like visual studio's team foundation server. See the change history of script file. Everyone must access that program and be able to put their scripts. Recover previous versions of script file. Execute these scripts over a selected database. Compare databases by procedures (not only by name, by content of procedure), functions, table columns, packages etc. I am searching a program like that. Which one do you suggest me?

  • shared_ptr requires complete type; cannot use it with lua_State*

    - by topright
    Hello! I'm writing a C++/OOP wrapper for Lua. My code is: class LuaState { boost::shared_ptr<lua_State> L; LuaState(): L( luaL_newstate(), LuaState::CustomDeleter ) { } } The problem is lua_State is incomplete type and shared_ptr constructor requires complete type. And I need safe pointer sharing. (Funny thing boost docs say most functions do not require complete type, but constructor requires, so there is no way of using it. http://www.boost.org/doc/libs/1_42_0/libs/smart_ptr/smart_ptr.htm) Can can I solve this? Thank you.

  • Multiple Controls on a Page with Multiple Instances of Javascript

    - by mattdell
    I have created a Web Control in ASP for use in integrating with Telligent CommunityServer. The control is written in ASP with some 10 lines of C# backend for controlling visibility of the UI elements based on permissions, but I'd say 90% of the functionality is straight-up Javascript. The control works beautifully, until you drop two instances of the Control on the same page--since they reference the exact same Javascript functions, only one control works. How can I take this functionality that I have, this 1200 lines of Javascript, and make it so that each instance of the control can reference its each unique instance of Javascript?

  • declaring a 2D array of pointer objects

    - by Tyler Stennette
    I'm having a tough time figuring out how to instantiate a 2D array of pointer objects. Here is how I'm doing it: Pieces* chessBoard[9][9]; When I want to set it to an actual object pointer, I'm doing the following: chessBoard[1][1] = new Rook(p1Rook); Rook is a class that inherits attributes from the Pieces class and p1Rook is a char variable set to 'R'. This class also implements virtual functions (not pure virtual) from Pieces such as move() or getPiece() that are unique to the particular chess piece. However, when I compile my program, I get the following error: ChessBoard.cpp:69: error: expected type-specifier before ‘Rook’ ChessBoard.cpp:69: error: cannot convert ‘int*’ to ‘Pieces*’ in assignment Can someone please explain what I should change to get rid of this rather annoying persistent error? I would appreciate it.
