• What is best way to measure the time cycles for a C# function ?

  - by Duaa

  Hi all: Really, I'm looking for a good function that measure the time cycles accurately for a given C# function under Windows operating system. I tried these functions, but they both do not get accurate measure: DateTime StartTime = DateTime.Now; TimeSpan ts = DateTime.Now.Subtract(StartTime); Stopwatch stopWatch = new Stopwatch(); stopWatch.Start(); stopWatch.Stop(); TimeSpan ts = stopWatch.Elapsed; Really, each time I call them, they give me different time for the same function Please, if anyone know better way to measure time consuming accurately, please help me and thanks alot alot

• Is there any free, open source php CMS\framework for described case?

  - by Ole Jak

  I want that cms\framework to create me tables like "Users" "Cameras" and so on and declare classes and simple default methods for them (like paged sql relults and so on). I mean I say to it: I want Users to have ID, SpecialNumber and Name Flilds. and I want to get from it class for table generation (to call it once) and class containing methods such as Search by ID, SpecialNumber and Name, Create User, Delit User and so on functions. Is there any framework/cms like this for working with CODE not ui's and so on... so to say PHP generator or something... The result should be as that framework free as possible. So Is there any free, open source php CMS\framework for described case?

• Updating variables in XSL

  - by Stroboskop

  Is there any way in XSL to update a global variable? I want to check what elements i already transformed and act accordingly. That would require me to somehow add the names of the elements to some sort of list and update it each time a new element is transformed. But since xsl:variable isn't "variable" in the sense one would expect, i have no way of adding anything to it once it has been defined. I have multiple included data files, so using xsl functions that only know the current set of nodes will not help.

• How to implement a private virtual function within derived classes?

  - by Dane

  Hi, I know why I want to use private virtual functions, but how exactly can I implement them? For example: class Base{ [...] private: virtual void func() = 0; [...] } class Derived1: puplic Base{ void func() { //short implementation is ok here } } class Derived2: puplic Base{ void func(); //long implementation elsewhere (in cpp file) } [...] void Derived2::func() { //long implementation } The first version is ok but not always possible. Isn't the second version simply name hiding? How do you define the Base::func() of Derived2, if you cannot do it within the class declaration of Dereived2? Thanks

• jquery ui-effects-wrapper causing havoc

  - by vondip

  Hi all, I am using jquery-ui and at some point I use the show and hide functions quite heavily to animate changing images coming in and out. From some reason, after a few tries all of a sudden the controls on my page stop responding to clicks. After a bit of poking arround using firebug I discovered my page is filled with div's of the class ui-effects-wrapper. I have no idea why this happens or how to stop it. If I remove these divs I can no longer see the images I've been animating. Any ideas?

• DeferWindowPos and SWP_SHOWWINDOW/SWP_HIDEWINDOW

  - by Tom Bell

  I am writing a virtual desktop application which utilises the DeferWindowPos API functions. The current method I am using is moving the windows off the screen if they're not on the current virtual desktop. However I know wish to also hide the windows that are off-screen so they do not appear on the task bar. I have attempted this by also passing SWP_SHOWWINDOW/SWP_HIDEWINDOW to the DeferWindowPos() calls. I have read a few sites regarding this and one of them suggested that if SWP_SHOWWINDOW/SWP_HIDEWINDOW are passed, then the window will only show or hide, and no reposition. Can anyone confirm this, or am I doing something wrong?

• Is there any way to retrieve a float from a varargs function's parameters?

  - by Jared P

  If the function was defined with a prototype which explicitly stated the types of the parameters, eg. void somefunc(int arg1, float arg2); but is implemented as void somefunc(int arg1, ...) { ... } is it possible to use va_arg to retrieve a float? It's normally prevented from doing this because varargs functions have implicit type promotions, like float to double, so trying to retrieve an unpromoted type is unsupported, even though the function is being called with the unpromoted type do to the more specific function prototype. The reason for this is to retrieve arguments of different types at runtime, as part of an obj-c interpreter, where one function will be reused for all different types of methods. This would be best as architecture independent (so that if nothing else the same code works on simulator and on device), although if there is no way to do this then device specific fixes will be accepted.

• jQuery version of YAHOO.lang (isUndefined, isNull, isString etc.)

  - by Chris S

  Does anyone know of a jQuery plugin that has 'helpers' or extensions like those found in the YAHOO.lang namespace? I have in mind functions such as: isNull isDefined isString isFunction I would also appreciate the same kind of thing for strings and arrays, such as Contains, StartsWith (I know these are easy to write, I'm just looking for a plugin that encompasses them all). It's not in the YAHOO.lang namespace but also form related extensions- determining a radiobox's value (from the one checked), a form element's type in a friendly name. Specifically a plugin with fluent API rather than selector based such as $("input[@type=radio][@checked]") Again I'm aware they're easy to implement but I don't want to reinvent the wheel.

• XCode iPhone OS Deployment Target Tool

  - by Trah Divad

  Problem I'm currently stuck trying to figure out what "iPhone OS Deployment Target" setting to use. I do not want to write conditional code right now, so I'd like the lowest version that runs my application fine. At first I thought it would be 2.0 as I wasn't using any 3.0 features, but then i realized that AVAudioRecorder is a 3.0 API. I don't want to be manually checking EVERY function I use in the documentation. Question Is there a tool that will check the OS availability of each functions you call in your code to figure out what the Deployment Target should be? That tool could be a good old compiler, but the latest version of the iPhone SDK does not come with the PRE-3.0 SDKs.

• Profiling help required

  - by Mick

  I have a profiling issue - imagine I have the following code... void main() { well_written_function(); badly_written_function(); } void well_written_function() { for (a small number) { highly_optimised_subroutine(); } } void badly_written_function() { for (a wastefully and unnecessarily large number) { highly_optimised_subroutine(); } } void highly_optimised_subroutine() { // lots of code } If I run this under vtune (or other profilers) it is very hard to spot that anything is wrong. All the hotspots will appear in the section marked "// lots of code" which is already optimised. The badly_written_function() will not be highlighted in any way even though it is the cause of all the trouble. Is there some feature of vtune that will help me find the problem? Is there some sort of mode whereby I can find the time taken by badly_written_function() and all of its sub-functions?

• Could someone explain __declspec(naked) please?

  - by Scott

  I'm looking into porting a script engine written for Windows to Linux; it's for Winamp's visualization platform AVS. I'm not sure if it's even possible at the moment. From what I can tell the code is taking the addresses of the C functions nseel_asm_atan and nseel_asm_atan_end and storing them inside a table that it can reference during code execution. I've looked at MS's documentation, but I'm unsure what __declspec(naked) really does. What is prolog and epilog code mentioned in the documentation? Is that related to Windows calling conventions? Is this portable? Know of any Linux-based examples using similar techniques? static double (*__atan)(double) = &atan; __declspec ( naked ) void nseel_asm_atan(void) { FUNC1_ENTER *__nextBlock = __atan(*parm_a); FUNC_LEAVE } __declspec ( naked ) void nseel_asm_atan_end(void) {}

• returning values from function or method multiple times by only calling the class once

  - by Sokhrat Sikar

  I have a members.php file that shows my websites members. I echo members name by using foreach method. A method of Members class returns an array, then I use foreach loop in the members.php file to echo the members. I am trying to aovid writing php code in my members.php file. Is there a way to avoid using foreach inside members.php file? For example, is it possible to return value from a method couple of times? (by only calling the object once). Just like how we normally call the functions? This question doesn't make sense, but I am just trying to see if there is a away around this issue?

• jQuery - How do I make the menu fadeout when the user clicks anywhere else in the document besides the menu itself?

  - by GirlGoneMad

  Hi, I have a link that functions similar to a drop down menu in that it fades in a list of links below it when clicked. Currently, the list fades back out when the link is clicked again, but I'd like for it to also fade out if the user clicks elsewhere on the page. I'm not sure how to add the $(document).click(function()... that handles this, or if this is even the right approach. Here is my code: $('#show_button').click( function(){ if(!$('#list').is(':visible')){ var pos = $('#show_button').offset(); $('#list').css({'left':pos.left - 11, 'top': pos.top+14}).fadeIn(); } else{ $('#list').fadeOut(); } }); I am trying to add something like this to make the list fade out when the user clicks anywhere else in the page: if($('#list').is(':visible')){ $(document).click(function() { $('#list').fadeOut(); }); } Thanks in advance - I would appreciate any help on this one :)

• Getting the last element of a Postgres array, declaratively

  - by Wojciech Kaczmarek

  How to obtain the last element of the array in Postgres? I need to do it declaratively as I want to use it as a ORDER BY criteria. I wouldn't want to create a special PGSQL function for it, the less changes to the database the better in this case. In fact, what I want to do is to sort by the last word of a specific column containing multiple words. Changing the model is not an option here. In other words, I want to push Ruby's sort_by {|x| x.split[-1]} into the database level. I can split a value into array of words with Postgres string_to_array or regexp_split_to_array functions, then how to get its last element?

• Confused as to why my PHP include isn't working

  - by Sam

  I had a prototype of my website working correctly, meaning it connected to the database correctly. This was done with just one file called "connect.php" which had mysql_connect() and such inside it. I then separated the connect information into to separate files, one containing the account information (account.php) and one containing the connect function (connect.php), with correct information (I triple checked) and it isn't connecting properly. All I can think of is that I'm not including it the right way. This is what I have in a file: <?php include('account.php'); include('connect.php'); include('functions.php'); ..... ?>

• Should I start with Trac 0.12 ?

  - by mree

  I'm going to start using Trac for the first time. From what I've gathered, the latest 0.12 is capable of supporting multiple project easily (which is something I will need since I got about 5 projects). However, it seems 0.12 is still in the development (0.12-dev). So, my question is, is it good enough for a newbie in Trac like me to use it? Does anyone has any experience using it ? It will be installed on a Linux server. BTW, I'll only be using the basic functions such as svn browser, wiki, tickets and others.

• Ruby On Rails CMS Framework

  Hi! I want to create a framework fo rails application. It will be a rails application but packed into gem (like a Radiant CMS). It must work like this: gem install cmsframework and then: cmsframework the_app After that we have a sceleton of rails app without any controllers etc.. - all controllers loaded from cmsframework gem.

But the main functionalities must be loaded from cmsframework gem. What is the best way to implement this?

• it is possible to "group by" without losing the original rows?

  - by toPeerOrNotToPeer

  i have a query like this: ID | name | commentsCount 1 | mysql for dummies | 33 2 | mysql beginners guide | 22 SELECT ..., commentsCount // will return 33 for first row, 22 for second one FROM mycontents WHERE name LIKE "%mysql%" also i want to know the total of comments, of all rows: SELECT ..., SUM(commentsCount) AS commentsCountAggregate // should return 55 FROM mycontents WHERE name LIKE "%mysql%" but this one obviously returns a single row with the total. now i want to merge these two queries in one single only, because my actual query is very heavy to execute (it uses boolean full text search, substring offset search, and sadly lot more), then i don't want to execute it twice is there a way to get the total of comments without making the SELECT twice? !! custom functions are welcome !! also variable usage is welcome, i never used them...

• Micro Controller Serial Data identification or classification

  - by Posiedon

  I have a x51 family micro controller (P89V51RD2). I'm going to send some data from computer using serial port. The data i'll be sending are Character 'S' Character 'R' and a 2 digit integer. Upon receiving the data, I will be calling separate functions. I used if(chr=='S') and elseif(chr=='R')for character data. The main problem lies with identifying the 2 digit number sent. Any other data other than the above three mentioned will be discarded. Any ideas for identifying two digit integer ??

• Remove duplicates in entries, scala way

  - by andersbohn

  I have a list of entries stating a production value in a given interval. Entries stating the exact same value at a later time adds no information and can safely be left out. case class Entry(minute:Int, production:Double) val entries = List(Entry(0, 100.0), Entry(5, 100.0), Entry(10, 100.0), Entry(20, 120.0), Entry(30, 100.0), Entry(180, 0.0)) Experimenting with the scala 2.8 collection functions, so far I have this working implementation: entries.foldRight(List[Entry]()) { (entry, list) => list match { case head :: tail if (entry.production == head.production) => entry :: tail case head :: tail => entry :: list case List() => entry :: List() } } res0: List[Entry] = List(Entry(0,100.0), Entry(20,120.0), Entry(30,100.0), Entry(180,0.0)) Any comments? Am I missing out on some scala magic?

• Alternatives to sign() in sqlite for custom order by

  - by Pentium10

  I have a string column which contains some numeric fields, but a lot are 0, empty string or null. The rest are numbers having different range, all positive. I tried to create a custom order by. The order would be done by two fields. First I would like to order the fields that have this number 0 and then sort by name. So something this would work: select * from table order by sign(referenceid) desc, name asc; But Sqlite lacks the sign() -1/0/1 function, and I am on Android and I can't create user defined functions. What other options I have to get this sort done.

• Is there any declare for toggle() that if its open do this, closed to that?

  - by Dejan.S

  Im doing some jquery stuff with toggle(), I'm doing different actions depending on if the current div is closing or showing, i know i can easy check if a div hasClass() or is(':visible') for what i want to do, but I'm thinking maybe there is somehow that i can reduce the amount of code or just do it more efficient? like declare the toggle() with two functions that this is for when its showing and this is for when its closing, is this possible? hope you get what i mean? like this, or check a jsfiddle $('#click_me').on('click', function() { $('#contain').toogle('blind', 300, function (){ alert('open'); }, function (){ alert('close'); }); });

• NotificationCenter Widget Failed To Use CoreLocation

  - by James Ye

  I'm writing a notification center widget, and it had to use location information. In normal apps I use CoreLocation and it works fine. But in my widget, I tried to locationServicesEnabled but it didn't go to the callback functions, and the authorizationStatus is always kCLAuthorizationStatusNotDetermined, and the authorize setting didn't show up in Setting - location service. I already set the delegate to the class. The system's Yahoo weather widget can auto locating and it uses CoreLocation too, so the widget do have ability to use location service. Why CoreLocation doesn't work on my widget?
