  • jquery validator message styling error in IE08 only when customised using errorPlacement function

    - by John Slaytor
    Going back to the errorplacement solution by Nadia (http://stackoverflow.com/questions/860055/jquery-override-default-validation-error-message-display-css-popup-tooltip-like) I have tried it and it works like a charm in Safari and Firefox but causes IE08 to bypass the jqueryvalidator and go straight to the server side validator. My code is this - as soon as I insert 'error element.... it is unstable in IE08. All help much appreciated <script type="text/javascript"> $(document).ready(function() { $("#sampleform").validate({ rules: { dinername: "required", venue: "required", contact: "required", dinertelephone: "required", venuetime: "required", numberdiners: "required", dineremail: { required: true, email: true}, datepicker: { required: true,date: true} }, messages: { dinername: "Your name?", numberdiners: "How many guests?", dinertelephone: "Your mobile?", venue: "Which restaurant?", venuetime: "Your arrival time?", datepicker: "Your booking date?", dineremail: "Please enter a valid email address", }, errorElement: "div", errorPlacement: function(error, element) { element.before(error); offset = element.offset(); error.css('right', offset.right); error.css('right', offset.right - element.outerHeight()); } }); }); </script> <script type="text/javascript"> $(function() { $("#datepicker") .datepicker({minDate: 0, maxDate: '+6M +0D',dateFormat: 'DD, d M yy',onClose: function() {$(this).valid();} }); }); </script> The relevant webpage is http://www.johnslaytor.com.au/nilgiris/forms/bookingform/bookingform.html

  • calling template function without <>; type inference

    - by Oops
    Hi, if I have a function template with typename T, where the compiler can set the type by itself, I do not have to write the type explicitely when I call the function like: template < typename T > T min( T v1, T v2 ) { return ( v1 < v2 ) ? v1: v2; } int i1 = 1, i2 = 2; int i3 = min( i1, i2 ); //no explicit <type> but if I have a function template with two different typenames like... template < typename TOut, typename TIn > TOut round( TIn v ) { return (TOut)( v + 0.5 ); } double d = 1.54; int i = round<int>(d); //explicit <int> Is it true that I have to specify at least 1 typename, always? I assume the reason is because C++ can not distinguish functions between different return types, true? but if I use a void function and handover a reference, again I must not explicitely specify the return typename: template < typename TOut, typename TIn > void round( TOut & vret, TIn vin ) { vret = (TOut)(vin + 0.5); } double d = 1.54; int i; round(i, d); //no explicit <int> should the conclusion be to avoid functions with return and more prefer void functions that return via a reference when writing templates? Or is there a possibility to avoid explicitely writing the return type? something like "type inference" for templates... is "type inference" possible in C++0x? I hope I was not too unclear. many thanks in advance Oops

  • JQuery function not working as expected

    - by Mike
    I've written a little function to position a logo midway between the left hand side of the browser window and the (centered) navigation menu. The menu items are populated from a database, with the first item given the id item0. function positionLogo(){ var $menuleft=0; var $element=document.getElementById('item0'); if ($element.offsetParent) { do { $menuleft+=$element.offsetLeft; } while ($element=$element.offsetParent); } var $logoleft=($menuleft/2)-130; // As logo is 260px wide if ($logoleft<0) { $logoleft=0; } $('#logo').css('left',$logoleft); } $(document).ready(function(){ positionLogo(); }); $(window).resize(function(){ positionLogo(); }); This works fine when the window is resized, but when it first runs when the page is loaded, the position it sets is about 20px too far right (ie $logoleft is 20 more than it should be). As soon as the page is resized it jumps into the correct position. Haven't got it live anywhere at the moment but does anyone have any ideas? Thanks!

  • Return an Oracle Associative Array from a function

    - by Paul Johnson
    Does anybody know if it is possible to return an associative array as the result of an Oracle function, if so do you have any examples? I have an Oracle package which contains an associative array declaration as defined below: TYPE EVENTPARAM IS TABLE OF NUMBER INDEX BY BINARY_INTEGER; This is then used in a stored procedure outside the package as follows: v_CompParams areva_interface.eventparam; The intention is to store an associative array of strings in the variable v_CompParams, returned from a Parse function in another package. The definition for which is as follows: PACKAGE STRING_MANIP IS TYPE a_array IS TABLE OF NUMBER INDEX BY BINARY_INTEGER; FUNCTION Parse (v_string VARCHAR2, v_delim VARCHAR2) RETURN a_array; FUNCTION RowCount(colln IN a_array) RETURN NUMBER; END; The code which implements this is: v_CompParams := STRING_MANIP.PARSE(v_CompID,v_Delim); Unfortunately it doesn't work, I get the error 'PLS-00382: expression is of wrong type'. I foolishly assumed, that since a_array derives from the same source Oracle type as the variable v_CompParams, that there would be no problem casting between them. Any help much appreciated. Kind Regards Paul J.

  • Is this trivial function silly?

    - by Chas. Owens
    I came across a function today that made me stop and think. I can't think of a good reason to do it: sub replace_string { my $string = shift; my $regex = shift; my $replace = shift; $string =~ s/$regex/$replace/gi; return $string; } The only possible value I can see to this is that it gives you the ability to control the default options used with a substitution, but I don't consider that useful. My first reaction upon seeing this function get called is "what does this do?". Once I learn what it does, I am going to assume it does that from that point on. Which means if it changes, it will break any of my code that needs it to do that. This means the function will likely never change, or changing it will break lots of code. Right now I want to track down the original programmer and beat some sense into him or her. Is this a valid desire, or am I missing some value this function brings to the table?

  • How To Get the Name of the Current Procedure/Function in Delphi (As a String)

    - by Andreas Rejbrand
    Is it possible to obtain the name of the current procedure/function as a string, within a procedure/function? I suppose there would be some "macro" that is expanded at compile-time. My scenario is this: I have a lot of procedures that are given a record and they all need to start by checking the validity of the record, and so they pass the record to a "validator procedure". The validator procedure raises an exception if the record is invalid, and I want the message of the exception to include not the name of the validator procedure, but the name of the function/procedure that called the validator procedure (naturally). That is, I have procedure ValidateStruct(const Struct: TMyStruct; const Sender: string); begin if <StructIsInvalid> then raise Exception.Create(Sender + ': Structure is invalid.'); end; and then procedure SomeProc1(const Struct: TMyStruct); begin ValidateStruct(Struct, 'SomeProc1'); ... end; ... procedure SomeProcN(const Struct: TMyStruct); begin ValidateStruct(Struct, 'SomeProcN'); ... end; It would be somewhat less error-prone if I instead could write something like procedure SomeProc1(const Struct: TMyStruct); begin ValidateStruct(Struct, {$PROCNAME}); ... end; ... procedure SomeProcN(const Struct: TMyStruct); begin ValidateStruct(Struct, {$PROCNAME}); ... end; and then each time the compiler encounters a {$PROCNAME}, it simply replaces the "macro" with the name of the current function/procedure as a string literal.

  • How to produce output using show function.

    - by wilson88
    I am trying to use sho to show the output of another function.The first function was used to do sorting, and returned a List. now I want to make a function that uses show() to display the output.This is how I had tried it only to get an error. Its to diplay the results of two the two sorted lists which used this function. map Auctioneer::compareBidList(map& one, map& two) and //**return Sorted.** void show(const char *msg, map<int, Bid*>& Sorted) { cout << msg << endl; show(Sorted); } void compare(map<int, Bid*>& sellers, map<int, Bid*>& buyers) { compare(sellers.begin(), sellers.end(), buyers.begin(),buyers.end(),compareBidList); } //my call in the main after declaration was as follows map<int, Bid*> buyers, sellers; Auctioneer auctioneer; auctioneer.compare(sellers,buyers); show(("Bids after sorting:", sellers,buyers);)

  • Pass a range into a custom function from within a cell

    - by Luis
    Hi I'm using VBA in Excel and need to pass in the values from two ranges into a custom function from within a cell's formula. The function looks like this: Public Function multByElement(range1 As String, range2 As String) As Variant Dim arr1() As Variant, arr2() As Variant arr1 = Range(range1).value arr2 = Range(range2).value If UBound(arr1) = UBound(arr2) Then Dim arrayA() As Variant ReDim arrayA(LBound(arr1) To UBound(arr1)) For i = LBound(arr1) To UBound(arr1) arrayA(i) = arr1(i) * arr2(i) Next i multByElement = arrayA End If End Function As you can see, I'm trying to pass the string representation of the ranges. In the debugger I can see that they are properly passed in and the first visible problem occurs when it tries to read arr1(i) and shows as "subscript out of range". I have also tried passing in the range itself (ie range1 as Range...) but with no success. My best suspicion was that it has to do with the Active Sheet since it was called from a different sheet from the one with the formula (the sheet name is part of the string) but that was dispelled since I tried it both from within the same sheet and by specifying the sheet in the code. BTW, the formula in the cell looks like this: =AVERAGE(multByElement("A1:A3","B1:B3")) or =AVERAGE(multByElement("My Sheet1!A1:A3","My Sheet1!B1:B3")) for when I call it from a different sheet.

  • Javascript function using "this = " gives "Invalid left-hand side in assignment"

    - by Brian M. Hunt
    I am trying to get a Javascript object to use the "this" assignments of another objects' constructor, as well as assume all that objects' prototype functions. Here's an example of what I'm attempting to accomplish: /* The base - contains assignments to 'this', and prototype functions */ function ObjX(a,b) { this.$a = a, $b = b; } ObjX.prototype.getB() { return this.$b; } function ObjY(a,b,c) { // here's what I'm thinking should work: this = ObjX(a, b * 12); /* and by 'work' I mean ObjY should have the following properties: * ObjY.$a == a, ObjY.$b == b * 12, * and ObjY.getB() == ObjX.prototype.getB() * ... unfortunately I get the error: * Uncaught ReferenceError: Invalid left-hand side in assignment */ this.$c = c; // just to further distinguish ObjY from ObjX. } I'd be grateful for your thoughts on how to have ObjY subsume ObjX's assignments to 'this' (i.e. not have to repeat all the this.$* = * assignments in ObjY's constructor) and have ObjY assume ObjX.prototype. My first thought is to try the following: function ObjY(a,b,c) { this.prototype = new ObjX(a,b*12); } Ideally I'd like to learn how to do this in a prototypal way (i.e. not have to use any of those 'classic' OOP substitutes like Base2). It may be noteworthy that ObjY will be anonymous (e.g. factory['ObjX'] = function(a,b,c) { this = ObjX(a,b*12); ... }) -- if I've the terminology right. Thank you.

  • 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 )

  • Delphi - Help calling threaded dll function from another thread

    - by cloudstrif3
    I'm using Delphi 2006 and have a bit of a problem with an application I'm developing. I have a form that creates a thread which calls a function that performs a lengthy operation, lets call it LengthyProcess. Inside the LengthyProcess function we also call several Dll functions which also create threads of their own. The problem that I am having is that if I don't use the Synchronize function of my thread to call LengthyProcess the thread stops responding (the main thread is still responding fine). I don't want to use Synchronize because that means the main thread is waiting for LengthyProcess to finish and therefore defeats the purpose of creating a separate thread. I have tracked the problem down to a function inside the dll that creates a thread and then calls WaitFor, this is all done using TThread by the way. WaitFor checks to see if the CurrentThreadID is equal to the MainThreadID and if it is then it will call CheckSychronization, and all is fine. So if we use Synchronize then the CurrentThreadID will equal the MainThreadID however if we do not use Synchronize then of course CurrentThreadID < MainThreadID, and when this happens WaitFor tells the current thread (the thread I created) to wait for the thread created by the DLL and so CheckSynchronization never gets called and my thread ends up waiting forever for the thread created in the dll. I hope this makes sense, sorry I don't know any better way to explain it. Has anyone else had this issue and knows how to solve it please?

  • Execute function without sending 'self' to it

    - by Sergey
    Is that possible to define a function without referencing to self this way? def myfunc(var_a,var_b) But so that it could also get sender data, like if I defined it like this: def myfunc(self, var_a,var_b) That self is always the same so it looks a little redundant here always to run a function this way: myfunc(self,'data_a','data_b'). Then I would like to get its data in the function like this sender.fields. UPDATE: Here is some code to understand better what I mean. The class below is used to show a page based on Jinja2 templates engine for users to sign up. class SignupHandler(webapp.RequestHandler): def get(self, *args, **kwargs): utils.render_template(self, 'signup.html') And this code below is a render_template that I created as wrapper to Jinja2 functions to use it more conveniently in my project: def render_template(response, template_name, vars=dict(), is_string=False): template_dirs = [os.path.join(root(), 'templates')] logging.info(template_dirs[0]) env = Environment(loader=FileSystemLoader(template_dirs)) try: template = env.get_template(template_name) except TemplateNotFound: raise TemplateNotFound(template_name) content = template.render(vars) if is_string: return content else: response.response.out.write(content) As I use this function render_template very often in my project and usually the same way, just with different template files, I wondered if there was a way to get rid of having to call it like I do it now, with self as the first argument but still having access to that object.

  • 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.

  • Sql server query using function and view is slower

    - by Lieven Cardoen
    I have a table with a xml column named Data: CREATE TABLE [dbo].[Users]( [UserId] [int] IDENTITY(1,1) NOT NULL, [FirstName] [nvarchar](max) NOT NULL, [LastName] [nvarchar](max) NOT NULL, [Email] [nvarchar](250) NOT NULL, [Password] [nvarchar](max) NULL, [UserName] [nvarchar](250) NOT NULL, [LanguageId] [int] NOT NULL, [Data] [xml] NULL, [IsDeleted] [bit] NOT NULL,... In the Data column there's this xml <data> <RRN>...</RRN> <DateOfBirth>...</DateOfBirth> <Gender>...</Gender> </data> Now, executing this query: SELECT UserId FROM Users WHERE data.value('(/data/RRN)[1]', 'nvarchar(max)') = @RRN after clearing the cache takes (if I execute it a couple of times after each other) 910, 739, 630, 635, ... ms. Now, a db specialist told me that adding a function, a view and changing the query would make it much more faster to search a user with a given RRN. But, instead, these are the results when I execute with the changes from the db specialist: 2584, 2342, 2322, 2383, ... This is the added function: CREATE FUNCTION dbo.fn_Users_RRN(@data xml) RETURNS varchar(100) WITH SCHEMABINDING AS BEGIN RETURN @data.value('(/data/RRN)[1]', 'varchar(max)'); END; The added view: CREATE VIEW vwi_Users WITH SCHEMABINDING AS SELECT UserId, dbo.fn_Users_RRN(Data) AS RRN from dbo.Users Indexes: CREATE UNIQUE CLUSTERED INDEX cx_vwi_Users ON vwi_Users(UserId) CREATE NONCLUSTERED INDEX cx_vwi_Users__RRN ON vwi_Users(RRN) And then the changed query: SELECT UserId FROM Users WHERE dbo.fn_Users_RRN(Data) = '59021626919-61861855-S_FA1E11' Why is the solution with a function and a view going slower?

  • 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?

  • 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)))

  • 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.

  • 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

  • C++ function overloading and dynamic binding compile problem

    - by Olorin
    #include <iostream> using namespace std; class A { public: virtual void foo(void) const { cout << "A::foo(void)" << endl; } virtual void foo(int i) const { cout << i << endl; } virtual ~A() {} }; class B : public A { public: void foo(int i) const { this->foo(); cout << i << endl; } }; class C : public B { public: void foo(void) const { cout << "C::foo(void)" << endl; } }; int main(int argc, char ** argv) { C test; test.foo(45); return 0; } The above code does not compile with: $>g++ test.cpp -o test.exe test.cpp: In member function 'virtual void B::foo(int) const': test.cpp:17: error: no matching function for call to 'B::foo() const' test.cpp:17: note: candidates are: virtual void B::foo(int) const test.cpp: In function 'int main(int, char**)': test.cpp:31: error: no matching function for call to 'C::foo(int)' test.cpp:23: note: candidates are: virtual void C::foo() const It compiles if method "foo(void)" is changed to "goo(void)". Why is this so? Is it possible to compile the code without changing the method name of "foo(void)"? Thanks.

  • 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!

  • 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 = $attributes['attributes']['class'] . " item-$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 $vars['primary_links_tree'] = menu_tree(variable_get('menu_primary_links_source', '$primary_links')); } Any ideas would be greatly appreciated.

  • 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.
