• Drop down selection not registered when form submitted quickly?!

  - by Abs

  Hello all, I have noticed a strange thing that happens on my web app when the server is under heavy loads (I am remoting on to the Windows Server). I have a drop down box which is generated dynamically (server side). When I make a selection and quickly press the submit button to indicate my selection the next page does not register my selection but if I do it a bit more slowly it will. I have not come across this before, has anyone? I know its a small issue but there are a lot of "trigger happy", including me... should I put a delay before the form is submitted? If I do, I can only guess the right amount of time. Or is there an underlying problem with my web app? Thanks all

• Questions regarding Web Service development in C++

  - by Eduardo León

  The purpose of this question is to play a joke, but the question itself is serious. Inspired by DOS on Dope, I want to make my own framework for Web Service development based on MFC serialization. However, my only experience in Web Service development consists in having written a toy ASP.NET Web Service. All I had to do to expose a method was... [WebMethod] public ReturnType ExposedMethod(InputType1 param1, InputType2 param2) { //... } ... and ASP.NET took care of the rest for me. Obviously, I will have to do everything by hand in my own framework. Thus, I would like to delve a bit more into the little details of how ordinary SOAP Web Services work, in order to replicate them. So I have mainly two questions: Where can I find the details on how SOAP Web Services work, and what ASP.NET hides from me? What are the main challenges I am going to find in my completely lunatic project?

• open window with dynamic content

  - by julio

  Is it possible to open a window from PHP that has predefined content? It's obvious how you can open a window from a javascript link that frames an existing page, or just do a target=_blank from a regular a tag that references an existing page. But I am generating a bit of content, and want that content to be opened in a new link (or streamed to the viewer)-- something like (clearly psuedo code!): $content = "Hello World. <br />Nice to meet you!"; <a href="#" target="_blank" content=$content>Open up!</a> Is this possible? Thanks!

• How can I change this method to get rid of the warning without anything changing?

  - by user3591323

  So this question:Warning-used as the name of the previous parameter rather than as part of the selector answers part of my problem, but I really don't want anything to change inside this method and I'm a bit confused on how this works. Here's the whole method: -(void) SetRightWrong:(sqzWord *)word: (int) rightWrong { if (self.mastered==nil) { self.mastered = [[NSMutableArray alloc]initWithCapacity:10]; } //if right change number right if (rightWrong == 1) { word.numberCorrect++; //if 3 right move to masterd list [self.onDeck removeObject:word]; if(word.numberCorrect >= 3 ) { [self.mastered addObject:word]; } else { //if not 3 right move to end of ondeck [self.onDeck addObject:word]; } } else if(rightWrong == 0) { //if wrong remove one from number right unless 0 NSUInteger i; i=[self.onDeck indexOfObject:word]; word = [self.onDeck objectAtIndex:i]; if (word.numberCorrect >0) { word.numberCorrect--; } } } The warning I am getting is: 'word' used as the name of the previous parameter than as part of the selector.

• Are there any real life uses for the Java byte primitive type?

  - by Thorbjørn Ravn Andersen

  For some inexplicable reason the byte primitive type is signed in Java. This mean that valid values are -128..127 instead of the usual 0..255 range representing 8 significant bits in a byte (without a sign bit). This mean that all byte manipulation code usually does integer calculations and end up masking out the last 8 bits. I was wondering if there is any real life scenario where the Java byte primitive type fits perfectly or if it is simply a completely useless design decision? EDIT: The sole actual use case was a single-byte placeholder for native code. In other words, not to be manipulated as a byte inside Java code.

• Question about software that tracks divs better than notepad++

  - by Jeff

  I recently got hired as a web developer, and the project that I am overseeing has a formatting issue on one of the pages because one of the divs is out of whack. It is a fairly complex page with quite a bit of php, and from what I can gather, I am missing a </div> tag somewhere, and accordingly everything is messed up. I am currently using notepad++, which is decent at lining up divs, meaning that if you click on the opening div tag, it will highlight purple and also highlight the closing one. But it seems as though if you have div tags that span several lines (hundreds) it won't work. Has anyone else run into a similar situation? Is there a better editor I could be using that would do a better job of helping me with my div issue? Or do I have to go through and line up the divs 1 by 1? (there are like over 100). Please let me know!! Thanks

• Evenly distribute range of specified values within a vector

  - by nofunsally

  I have a vector A and I want to populate it with values as evenly as possible. For example, if A is 1x30 and I want to use three values I would use a code like this below: % A = zeros(1,30); A([1:10])=0; A([11:20])=1; A([21:30])=2; This works, but seems a bit cumbersome to me. Is there a more elegant way to evenly (as possible) distribute a specified range of values within a vector? I am intent on keeping each of the values in "clumps." Thank you kindly in advance.

• C++ STL: Array vs Vector: Raw element accessing performance

  - by oh boy

  I'm building an interpreter and as I'm aiming for raw speed this time, every clock cycle matters for me in this (raw) case. Do you have any experience or information what of the both is faster: Vector or Array? All what matters is the speed I can access an element (opcode receiving), I don't care about inserting, allocation, sorting, etc. I'm going to lean myself out of the window now and say: Arrays are at least a bit faster than vectors in terms of accessing an element i. It seems really logical for me. With vectors you have all those security and controlling overhead which doesn't exist for arrays. (Why) Am I wrong? No, I can't ignore the performance difference - even if it is so small - I have already optimized and minimized every other part of the VM which executes the opcodes :)

• SQLce create table "index field" explanation (SQL Management Studio) ?

  - by bretddog

  Hi, I'm new to databases, and now creating SQLCE database in Management Studio. There is a value in brackets; [UQ_Users_0000000000000028], which seems a bit random to me, so would just like to ask if someone could explain this field? Is it just simply required to be a unique field? Is there any reason why I would want to change it to something else than what SSMS scripts? cheers! CREATE TABLE [Users] ( [UserID] int NOT NULL ..... CREATE UNIQUE INDEX [UQ__Users__0000000000000028] ON [Users] ([UserID] ASC);

• What is the main purpose of WebExceptionStatus.Success?

  - by csharpenter

  I am a bit confused about the purpose of the enum value Success of the WebExceptionStatus enumeration. I did a search and did not find this enumeration being used outside the WebException class. This is very confusing to me. Why would an exception be used to indicate a successful action/state. Am I missing something, or did I not search thouroughly enough? Was it introduced for future functionality? Please if anyone does know its basic purpose I would be thankfull if s/he shares with us the explanation.

• Drupal: create a node with employee working hours

  - by JMarshall

  I have a bit complicated task. 1. I need to create a node with employee working hours (it's gonna be created for all users with role "employee"), which looks like this: Monday: From __ : __ To __ : __ Tuesday: From __ : __ To __ : __ Wednesday: From __ : __ To __ : __ etc. So, I'll have to create probably 14 CCK fields (monday_from, monday_to, tuesday_from...) or more to store the day of the week and workging hours (hours and minutes). 2. I need to add a view with exposed filters, where visitors can filter employees by day of the week and working hours. What kind of field should I use for working hours? How could views filtering described above be achieved? Any suggestions are greatly appreciated. Thank you!

• How to completely remove MySQL from a windows 7 machine

  - by Jazibobs

  I'm new to MySQL struggling to find a version and workbench which works stably on my 64 bit windows 7 machine. I've decided to attempt to completely remove MySQL from my machine and to restart the installation process from scratch. However, after uninstalling all software linked with MySQL using conventional control panel uninstalling means some MySQL windows services still remain on my machine. I can't see any obvious method to remove these and they have since been causing me difficulties when trying to install different versions of MySQL. Could anyone please advise?

• Can JavaScript be overused?

  - by ledhed2222

  Hello stackoverflow, I'm a "long time reader first time poster", glad to start participating in this forum. My experience is with Java, Python, and several audio programming languages; I'm quite new to the big bad web technologies: HTML/CSS/JavaScript. I'm making two personal sites right now and am wondering if I'm relying on JavaScript too much. I'm making a site where all pages have a bit of markup in common--stuff like the nav bar and some sliced background images--so I thought I'd make a pageInit() function to insert the majority of the HTML for me. This way if I make a change later, I just change the script rather than all the pages. I figure if users are paranoid enough to have JavaScript turned off, I'll give them an alert or something. Is this bad practice? Can JavaScript be overused? Thanks in advance.

• Getting 'choice' to work in Highline Ruby Gem without error and getting variable from it

  - by The Warm Jets

  I'm having a couple of problems using Highline in Ruby, and trying to get the choice element, detailed here, to work. At the moment the following code produces the error "error: wrong number of arguments (0 for 1). Use --trace to view backtrace" How do I get the variable out of choice? At the moment I have the 'do' setup, but I have no idea about how to get the variable the user has chosen out and into a variable for use elsewhere. Sorry if this is a bit beginner, I'm brand new to ruby and this is my first project, in at the deep end. Thanks in advance. if agree("Are these files going to be part of a set?

• Django: IE doesn't load locahost or loads very SLOWLY

  - by reedvoid

  I'm just starting to learn Django, building a project on my computer, running Windows 7 64-bit, Python 2.7, Django 1.3. Basically whatever I write, it loads in Chrome and Firefox instantly. But for IE (version 9), it just stalls there, and does nothing. I can load up "http://127.0.0.1:8000" on IE and leave the computer on for hours and it doesn't load. Sometimes, when I refresh a couple of times or restart IE it'll work. If I change something in the code, again, Chrome and Firefox reflects changes instantly, whereas IE doesn't - if it loads the page at all. What is going on? I'm losing my mind here....

• Android App Support Options

  - by Pughjl

  I've got a free app I'm planning on submitting to the marketplace. Looking over the submission form I see they expect a web site or email for support. Users?! I've got to worry about users if I submit an app? I suppose I would like to get some abuse from users, but I don't want to go broke doing it. So what are my options? I have a web site--I suppose I could install forum software on it--that sounds like a lot of work though. Some apps reference a blogspot page--or I could use my Word Press site. They seems a bit disorganized for getting user feedback though.

• Using an int as the numerical representation of a string in C#

  - by bluewall21

  I'm trying to use an integer as the numerical representation of a string, for example, storing "ABCD" as 0x41424344. However, when it comes to output, I've got to convert the integer back into 4 ASCII characters. Right now, I'm using bit shifts and masking, as follows: int value = 0x41424344; string s = new string ( new char [] { (char)(value >> 24), (char)(value >> 16 & 0xFF), (char)(value >> 8 & 0xFF), (char)(value & 0xFF) }); Is there a cleaner way to do this? I've tried various casts, but the compiler, as expected, complained about it.

• Getting imagename and make link from <img> with jQuery

  - by Bulan

  With jQuery, I want to make all images under a specific path on a site clickable and showing a big image using Fancybox, which is a lighbox variant plugin for jQuery. My small images are located under "images/products/small", the big ones under "images/products/big" and the imagename is always the same The page is showing the image with the following code: <img src="images/products/small/hat.jpg" alt="Nice hat"> What i want is some jQuery script that makes this into: <a href="images/products/big/hat.jpg" class="fancybox"><img src="images/products/small/hat.jpg" alt="Nice hat"></a> Maybe the part with setting class on the link tag can be skipped and just activate fancybox on the element directly with $(elm).fancybox(); I was looking around a bit and it looks like the jQuery functions "attr" and "wrap" might be useful, but with my currently limited jQuery skills I can't really connect the dots.

• About memory and delete object in c++

  - by barssala

  I will give some examples and explain. First, I declare some object like CString* param = new CString[100] And when I declare this one, my memory would increase a little bit because it's some implemented string. Then I store this object in some list of CString just like List<CString> myList = new List<CString>; // new list of CString myList.add(param); This is my question: I wanna know, when I delete myList, my param isn't deleted, right? And memory in param still exists. Do I misunderstand?

• ANSI C++: Diferences between delete and delete[]

  - by Sunscreen

  I was looking a snipset of code: int* ip; ip = new int[100]; delete ip; The example above states that: "This code will work with many compilers, but it should instead read:" int* ip; ip = new int[100]; delete [] ip; Is this indeed the case? I use the compiler "Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 11.00.7022 for 80x86" and does not complain (first example) while compiling. At runtime the pointer is set to NULL. Other compilers behave diferrently? Can a compiler not compain and issues can appear at runtime? Thanks, Sun

• Using a database/index sequential file independently of the Unix distribution

  - by Helper Method

  What I'm planning to do is a) parse a file for some lines matching a regular expression b) store the match in some sort of database / file so I don't have to do the parsing again and again c) call another program passing the matches as arguments While I can imagine how to do a) and c), I'm a little bit unsure about b). The matches are of the form key:attribute1:attribute2:attribute3 where attribute 2 may be optional. I'm thinking of storing the results in a simple database but the problem is the database needs to available on a number of Unix platform for the program to work. Are there any (simple) databases which can be found on any Unix platforms? Or should I use some sort of index-sequential file?

• Class templating std::set key types

  - by TomFLuff

  I have a class to evaluate set algebra but wish to template it. At the minute it looks a bit like this set.h: template<typename T> class SetEvaluation { public: SetEvaluation<T>(); std::set<T> evaluate(std::string in_expression); } set.cpp template<typename T> std::set<T> SetEvaluation<T>::evaluate(std::string expression) { std::set<T> result; etc etc... } But i'm getting undefined reference errors when compiling. Is it possible to declare the return type as std::set<T> and then pass std::string as the class template param. There are no errors in the class but only when I try to instantiate SetEvaluation<std::string> Can anyone shed light on this problem? thanks

• movedown method not saving new position - cakephp tree

  - by Ryan

  Hi everyone, I am experiencing a problem that has popped up recently and is causing quite a bit of trouble for our system. The app we have relies on using the movedown method to organize content, but as of late it has stopped working and began to generate the following warning: Warning (2): array_values() [<a href='function.array-values'>function.array-values</a>]: The argument should be an array in [/usr/local/home/cake/cake_0_2_9/cake/libs/model/behaviors/tree.php, line 459] The line being referenced: list($node) = array_values($Model->find('first', array( 'conditions' => array($scope, $Model->escapeField() => $id), 'fields' => array($Model->primaryKey, $left, $right, $parent), 'recursive' => $recursive ))); The line calling the method: $this->movedown($id,abs((int)$position)); I have exhausted every idea I could come up with. Has anyone else crossed this issue before? Any help, or pointing in a direction would be much appreciated!

• Recommand a Perl module to persist a large object for re-use between runs?

  - by Alnitak

  I've got a large XML file, which takes 40+ seconds to parse with XML::Simple. I'd like to be able to cache the resulting parsed object so that on the next run I can just retrieve the parsed object and not reparse the whole file. I've looked at using Data::Dumper but the documentation is a bit lacking on how to store and retrieve its output from disk files. Other classes I've looked at (e.g. Cache::Cache) appear designed for storage of many small objects, not a single large one. Can anyone recommend a module designed for this?

• How is the implicit segment register of a near pointer determined?

  - by Daniel Trebbien

  In section 4.3 of Intel 64® and IA-32 Architectures Software Developer's Manual. Volume 1: Basic Architecture, it says: A near pointer is a 32-bit offset ... within a segment. Near pointers are used for all memory references in a flat memory model or for references in a segmented model where the identity of the segment being accessed is implied. This leads me to wondering: how is the implied segment register determined? I know that (%eip) and displaced (%eip) (e.g. -4(%eip)) addresses use %cs by default, and that (%esp) and displaced (%esp) addresses use %ss, but what about (%eax), (%edx), (%edi), (%ebp) etc., and can the implicit segment register depend also on the instruction that the memory address operand appears in?
