  • Pass associative arrays in call_user_func_array(...)

    - by Matt
    Hey all, I'm building a templating system and I'm running in to an issue with calling functions on the fly. When I try the following: $args = array( 4, 'test' => 'hello', 'hi' ); You know.. some numerical elements some associative elements, call_user_func_array($function, $args); converts the array to something like this: $args = array( 4, 'hello', 'hi' ); Is there any way around this other than passing an array like this: $args = array( 4, array('test' => 'hello'), 'hi' ); Thanks! Matt

  • XML RSS to HTML parser doesn't work

    - by mstr
    I'm using MCX (I don't even know if someone here is familiar with it, pretty unkown derivate of COBOL and Fortran, look it up in google when you don't believe me) Note: I'm using MCX on the MCX-WebServices server as it does neither support apache or ISS, mabye that is one problem. The thing is that I want to use the XML library to read in an XML file and convert it into an output format readable by the user. The XML lib already has all the functions I need for that, yet my program fails. #!usr/bin/mcx $PGRM.ID: index.mcx $PGRM.AT: /mstr SHOWERROR: WRITE XML.LastError --> OUTPUT DO_FLUSH xcit end\ MAIN: IMPORT Extras.XML USE Extras $XML_RSS_FILE: XML.ReadIn "rss.xml" ! $XML_RSS_FILE --> GOTO SHOWERROR $XML_RSS: XML.FormatRSS1 <-- $XML_RSS_FILE ! $XML_RSS --> GOTO SHOWERROR WRITE $XML_RSS --> OUTPUT DO_FLUSH FLUSH xcit end\ Program output: Nothing The rss.xml file 100% exists and is readable Thanks in advance

  • Recursive vs. Iterative algorithms

    - by teehoo
    I'm implementing the Euclidian algorithm for finding the GCD (Greatest Common Divisor) of two integers. Two sample implementations are given: Recursive and Iterative. http://en.wikipedia.org/wiki/Euclidean_algorithm#Implementations My Question: In school I remember my professors talking about recursive functions like they were all the rage, but I have one doubt. Compared to an iterative version don't recursive algorithms take up more stack space and therefore much more memory? Also, because calling a function requires uses some overhead for initialization, aren't recursive algorithms more slower than their iterative counterpart?

  • C#: Access 32-bit/64-bit DLL depending on platform

    - by Thorsten Dittmar
    Hi, we use a self-written 32bit C++ DLL from our C# applications. Now we've noticed that when the C# applications are run on a 64bit system, the 64bit runtime is automatically used and of course the 32bit DLL can not be accessed from the 64bit runtime. My question is: is there a way of using the 32bit DLL? If not, if I created a 64bit version of the DLL, would it be easily possible to let the application choose which one to P/Invoke to? I'm thinking of creating two helper classes in C#: One that imports the functions from the 32bit DLL and one that imports from the 64bit DLL, then creating a wrapper class with one function for each imported function that calls either the 32bit importer or the 64bit importer depending on the "bittyness" of the OS. Would that work? Or is there another easy way to do things?

  • Is there anyway to enable MultiSelect in the StyledTextCtrl

    - by John Baker
    I've noticed that the StyledTextControl (Scintilla basically) in wxWidgets has a great feature that allows multi-selections of text, just like TextMate. However wxRuby doesn't seem to have the function calls to support that feature. I'm wonder if there is a way to enable it or if there might be a way I could rewrite that wrapper to include that function. It seems strange that they would purposely omit that since they are seemingly pretty exhaustive on most functions calls. Any insight on this would be greatly appreciated. I'm trying to write an open source TextMate clone in Ruby and it's gonna be pretty hard without MultiSelect, I could probably hack something together but it'd be ugly. Thanks ahead of time.

  • Snatching the code of a Facebook fan page canvas?

    - by Andre
    I am trying to snatch the code of this fan page: http://www.facebook.com/pages/See-oho-nieps-YothG-RRofiLe/106340746065367 I need the function that suggests the fan page to the users friends automatically (not for spamming purposes as the above fan page is used for). Now by looking at the source, I know that the code is under the pagelet_tab_content, but not all of it. I have copied that part and pasted it into my own fan page. The layout looks identical but the functions does not work. Obviously something is missing. For instance, I cant find the in the source which is strange, as I know for definate that it is being used. I have been working with this all day without any result. Maybe there is someone more intelligent and experienced that could help me out?

  • SQL Split function.

    - by Wardy
    Hi guys, I'm looking for a way to do this ... SELECT FirstName, LastName, Split(AddressBlock, ' ', 1), Split(AddressBlock, ' ', 2), PostCode FROM Contacts The arguments I want to pass are ... The address The separator (current situation requires 2 spaces but this might be a comma or a space followed by a comma) or something else (it varies). The address part I want to return (i don't always need all parts of the split result). I seem to be able to find a few examples of splitting functions about the internet but they return a table containing the entire set of split parts. My SQL skills aren't that great so I need the answer to be ultra simple. I'm always working with nvarchar data and the function needs to be reusable.

  • Jquery Widget Performance

    - by jamie-wilson
    I am working on an interface which involves ALOT of javascript. There is a calendar and blocks drawn on the calendar. The calendar is a jQuery widget, which works beautifully. The blocks drawn on top are also jQuery widgets. While it works - I am wondering, every time I create another block, is the widget fully duplicating, or is it referencing the widget? If I end up with 200 blocks on the screen, do I have 200 copies of the widget? Because if so i'm sure this will impact the performance quite heavily. Also it would determine whether I have functions inside the widget, or have them external to the widget looking in if that makes sense. Just putting some feelers out there for thoughts. I couldn't find anything by searching online.

  • C# Threads.Abort()

    - by Betamoo
    If a thread is running a function func1 that calls another function func2 inside it... Then I called thread.Abort() Will this stop func1 only OR func1 and func2 and all the functions func1 has called?? Thanks Edit: Here are more detail: func1 is called in a new thread, it continuously calls func2 on regular basis... func2 begin doing some work only if some array is not null.. it finishes it and return When supervisor wants to save data, it aborts Thread of func1- and then makes array null, saves data, then fill in the array with new one.. and starts Thread with func1 again.. Sometimes exception is raised because array is null in func2.. so func1 abort did not affect func2

  • Clipping the caret in a C# program

    - by Bob Sammers
    I'm creating a WinForms control in C# (using VS2008, .net 3.5) which allows text input. I've imported the necessary Win32 API functions from User32.dll for displaying the normal Windows caret and these are all working fine, but it's not displaying exactly how I'd like it. Text is displayed on the control with a blank border and I use Graphics.SetClip() to leave this margin clear. I want the caret to be clipped to the same region, but since I don't paint it and there's no obvious API function to set a clipping region, I can't see any way of doing this. Have I missed anything obvious? The caret is clipped inside the control in which it is drawn. I'm therefore aware that one solution could be to place the text in a separate sub-control with no border. However, if there's a simpler way than redesigning this part of the control, I'd like to look for that first. Thanks in advance for any help!

    Hi guys! So, i have a application that displays tasks and i created an option in the Settings menu that lets you choose in how many days all (Never, 10 days, 20 days or 30 days) these tasks should be automatically deleted. So when i open up the app there will be a method that will be called and check if theres any tasks to be deleted. I did that to challenge myself, but i'm hitting the wall with my head and i cant come up with something. So here i am in need of help! A little more information: i was trying to do something with java/android code, but from past searches i saw people dealing with it using SQL functions. Is it better? Thanks in advance guys!

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

  • GDB skips over my code!

    - by sheepsimulator
    So, I've defined a class like DataLoggingSystemStateReceiver { DataLoggingSystemStateReceiver() { // stuff } // ... other functions here }; In main, I instantiate DataLoggingSystemStateReceiver like so: int main() { // ... run stuff Sensor sensor(port, timer); DataLoggingSystemStateReceiver dlss(); Log::notice("started"); return 0; } However, when I step through this code in gdb, it runs: Sensor sensor(port, timer); skips DataLoggingSystemStateReceiver dlss(); and continues with Log::notice("started"); What gives? EDIT: By changing DataLoggingSystemStateReceiver dlss(); to DataLoggingSystemStateReceiver dlss; in main(), the line executes. Can someone explain why?

  • Calling a function of en external javascript file

    - by strakastroukas
    Hello. In general... How can I make a call on a function of an external javascript file? More specific... In the head tag i have <script type="text/javascript" src="JScript/FontSize.js"></script> The external javascript file, (that i would like to call) FontSize.js contains the following functions. function checkCookie() function setCookie(c_name, value, expiredays) function getCookie(c_name) function increaseFontSize() function decreaseFontSize() The FontSize.js is located at the ~/Jscript/ directory I guess the body on load should contain something like <body onload="/JScript/Fontsize.js/checkCookie()"> Of course nothing works as it should because, i do not know how to make the call to a function to an external js file

  • PostgreSQL - CREATE INDEX

    - by mocopera
    Hi! I'm working with PostgreSQL to create some data types written in C. For example, I have: typedef struct Point3D { char id[50]; double x; double y; double z; } Point3D; The input and output functions are working properly. But the problem is the following: Every id of Point3D must be unique (and can be NULL), so I have decided to create an unique index on this field id, but is that possible? I'm thinking in something like this: create unique index test_point3d_idx on test_point3d (( getID(columname) )); where getID returns the field ID of columname. But I need to implement getID and I am really blocked. Any advice?

  • Why dont Android applications provide an "Exit" option?

    - by Howiecamp
    Is there something in the Android developer guidelines that disuadea developers from providing the option to "exit" (stop running) an application from within the application itself? I love multitasking and all but it's not clear to me why: the vast majority of apps don't have their own Exit functions and hence just keep running forever don't give you a choice about running when you turn on the phone - they just do by default Both of these things lead to memory usage constantly increasing and your device running with this performance burden all of the time despite the fact that you may only want certain apps to run some of the time. Am I missing something?

  • Cross-reference between delphi records

    - by Paul-Jan
    Let's say I have a record TQuaternion and a record TVector. Quaternions have some methods with TVector parameters. On the other hand, TVector supports some operations that have TQuaternion parameters. Knowing that Delphi (Win32) does not allow for forward record declarations, how do I solve this elegantly? Using classes is not really an option here, because I really want to use operator overloading for this rare case where it actually makes good sense. For now I simply moved these particular methods out of the records and into separate functions, the good old-fashioned way. Better suggestions are most welcome.

  • How do you get notified of your repos' updates?

    - by furtelwart
    I'm working on several repositories at work and would like to be informed, if anything changes in the SVN repositories. I made a small BAT script (yes, BAT is usefull sometimes) that keeps executing an svn log -r BASE:HEAD on my working copy. It shows all submit comments and revision dates. It works really well but it's not comfortable for different repositories. How do you keep track of changes in your repositories? Do you use a small program you made for yourself? Do you use software someone else made? I'm interested in every approach to this problem. I would like to get notifications and several more information about the commit. The IDE integrated functions are good, but work only if I request the information. I don't want to act to get this information. Platform: Windows, Subversion 1.5 and higher.

  • Multiple key/value pairs in HTTP POST where key is the same name

    - by randombits
    I'm working on an API that accepts data from remote clients, some of which where the key in an HTTP POST almost functions as an array. In english what this means is say I have a resource on my server called "class". A class in this sense, is the type a student sits in and a teacher educates in. When the user submits an HTTP POST to create a new class for their application, a lot of the key value pairs look like: student_name: Bob Smith student_name: Jane Smith student_name: Chris Smith What's the best way to handle this on both the client side (let's say the client is cURL or ActiveResource, whatever..) and what's a decent way of handling this on the server-side if my server is a Ruby on Rails app? Need a way to allow for multiple keys with the same name and without any namespace clashing or loss of data.

  • Getting data from function loaded after current function

    - by Hwang
    I have 2 functions, 1 loaded before another. Some value are determine by the other function data, but since one of it has to load before the other 1, how should I get the data that is loaded after current function? private function wMessage():void { Message.width=Name.width+20; } private function wName():void { Name.x=(Message.x+Message.textWidth)-Name.textWidth; Name.y=Message.y+Message.height; } I've taken out some other unnecessary codes, but as you can see Name position is set according by the position + width of Message, but I want Message's width to be not smaller than Name

  • The cost of nested methods

    - by Palimondo
    In Scala one might define methods inside other methods. This limits their scope of use to inside of definition block. I use them to improve readability of code that uses several higher-order functions. In contrast to anonymous function literals, this allows me to give them meaningful names before passing them on. For example: class AggregatedPerson extends HashSet[PersonRecord] { def mostFrequentName: String = { type NameCount = (String, Int) def moreFirst(a: NameCount, b: NameCount) = a._2 > b._2 def countOccurrences(nameGroup: (String, List[PersonRecord])) = (nameGroup._1, nameGroup._2.size) iterator.toList.groupBy(_.fullName). map(countOccurrences).iterator.toList. sortWith(moreFirst).head._1 } } Is there any runtime cost because of the nested method definition I should be aware of? Does the answer differ for closures?

  • 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
