  • Code equivalence between Javascript and PHP

    - by xdevel2000
    I'm trying to learn PHP and I wish to know if there are some function equivalence constructs: In JS I can do: var t = function() {}; t(); myObj.DoStuff = function() {} // here I add a method at run-time myObj.DoStuff(); myObj["DoStuff"](); var j = myObj.DoStuff; j(); and so other things with function evaluation. In Js objects are associative arrays so every properties is accessible with the subscript notation... Can I add a method at run-time to a class template so next its object instances can have it? In JS I can do that via a prototype function property.

  • Good memory profiling, leak and error detection for Windows

    - by Fernando
    I'm currently looking for a good memory / leak detection tool for Windows. A few years ago, I used Numega's Boundschecker, which was VERY good. Right now it seems to have been sold to Compuware, which apparently sold it again to some other company. Trying to evaluate a demo of the current version has been so far very frustrating, in the best "enterprisy" tradition: (a) no advertised prices on their website (Great Red Flashing Lights of Warning); (b) contact form asked for number of employeers and other private information; (c) no response to my emails asking for a evaluation and price. I had to conclude that BoundsChecker is now one of "those" products. Y'know, the type where you innocently call and tomorrow 3 men in black suits turn up at your building wanting to talk to you about "partnerships" and not-so-secretly gauge the size of your company and therefore how much they can get away with charging you. SO, rant aside, can anyone recommend an excellent memory checking/leak detection tool, how much it costs, and suggestions for where to buy?

  • Passing expression as a parameter in Call by reference

    - by darkie15
    All, When we are passing an expression as a parameter, how does the evaluation occur? Here is a small example. This is just a pseudocode kind of example: f (x,y) { y = y+1; x = x+y; } main() { a = 2; b = 2; f(a+b, a) print a; } When accessing variable x in f, does it access the address of the temp variable which contains the result of a+b or will it access the individual addresses of a and b and then evaluate the value of a+b Please help. Regards, darkie15

  • Place an object on top of stack in ILGenerator

    - by KiNGPiN
    I have to pass a function an instance of an object, so obviously all the information to be taken as argument is to be loaded onto the evaluation stack Here is the code that i am looking for someClass SomeObject = new someClass(); il.Emit(OpCodes.LoadObject, SomeObject); il.Emit(OpCodes.CallVirt, MethodInfo Function); public void Function(Object obj) { Type type = typeof(obj); //do something w.r.t to the type } I dont require any information stored in the class just the type and i cannot use any of the primitive types to take my decision on Last i read that i can use a pointer to load the type using some opcodes ... but i am completely lost here, any help or pointers to the right direction would be great :)

  • If you were developing shareware softwares for windows, would you target the .Net Framework or use n

    - by bohoo
    For the sake of the question, by 'shareware' I mean a software which is relatively small in size (up to few dozens of mb) and available for download and evaluation through a web site. I'm asking this question, because I don't understand something regarding the current state of windows commercial desktop development. It seems to me that: There is no reliable statistic regarding the extent of windows systems with .Net Framework installed. It makes no sense to force the end user to install the 20-60mb .Net for an application which may be smaller. Applications conforms to the term 'shareware' above have a big share on the win os market. Much of them don't need the capabilities of low level languages like c++, and therefore ideally they should be developed with a RAD enviroment. So, One would suppose there will be a blossom of RAD enviroments for native win code. But I know about only one - Delphi, and Delphi is so unpopular. How is that?

  • update columns when value is numeric in tsql

    - by knittl
    i want to normalize date fields from an old badly designed db dump. i now need to update every row, where the datefield only contains the year. update table set date = '01.01.' + date where date like '____' and isnumeric(date) = 1 and date >= 1950 but this will not work, because sql does not do short circuit evaluation of boolean expressions. thus i get an error "error converting nvarchar '01.07.1989' to int" is there a way to work around this? the column also contains strings with a length of 4, which are not numbers (????, 5/96, 70/8, etc.) the table only has 60000 rows

  • How can I access form elements when using an ASP.NET MVC Ajax form?

    - by Patrick
    I've got an ajax form in an MVC 2 application. I cannot find the proper way to access the form elements within the Ajax form decleration. I can access the name of the elements with Request.Form.Keys but I can't access the actual values. I've read numerous examples of posting forms with jQuery but my form has elements created dynamically based on route values (sometimes it could be 2 text boxes sometimes 10, given unique names like so: <%= Html.TextBox("Evaluation"+Model.EvaluationId.ToString())) so I couldn't find a way to make that work with jQuery. Is there another way that I for elements can be accessed?

  • What are good resources to learn Coldfusion for a job application...

    - by NoMoreZealots
    The job title is "ColdFusion Developer." I have bit's HTML and Javascripting experience, but mostly have worked in the "harder" languages such as C and C++ with occational flurries of assembly. I'm currently employeed, but in the current job climate I figure it can't hurt to be looking around and applying for other positions. Plus according to the friend who sent me the job posting, it is suppose to pay "very well." They left my office to work for this company themself so I figure it's a reasonable evaluation of the company. I don't know if there are any free tools that I could use to get my feet wet and bone up for an interview, or what sort of literature is decent for the ColdFusion. Plus any ideas on how to tune a resume for it would also be helpful.

  • c# how to read the message store on a windows mobile device 6

    - by druffmuff
    Hi, can anyone post an example how to read the messagestore on a windows mobile device 6? I done this with "InTheHand": foreach (InTheHand.WindowsMobile.PocketOutlook.SmsMessage mess in sess.SmsAccount.SentItems) { if (mess.Received.Year == thisYear && mess.Received.Month == thisMonth) { smsThisMonth++; } } The problem is, that I only have a evaluation version of InTheHand. I would like to do this with OpenNetCF or mapidotnet, if possible. But I didn't figure out how to do this with OpenNetCF and mapitdotnet isn't available anymore on the sourceforge site (http://sourceforge.net/projects/mapidotnet/). I only found it on the svn directory, but there are no dlls.

  • Regex problem ...

    - by carlos
    hello i have the next regex Dim origen As String = " /c /p:""c:\mis doc umentos\mis imagenes construida\archivo.txt"" /cid:45 423 /z:65 /a:23 /m:39 /t:45rt " Dim str As String = "(^|\s)/p:""\w:(\\(\w+[\s]*\w+)+)+\\\w+.\w+""(\s|$)" Dim ar As Integer Dim getfile As New Regex(str) Dim mgetfile As MatchCollection = getfile.Matches(origen) ar = mgetfile.Count When i evaluate this it works, and gets the /p:""c:\mis doc umentos\mis imagenes construida\archivo.txt"" that basically is the path to a file. But if I change the origen string to Dim origen As String = " /c /p:""c:\mis doc umentos\mis imagenes construida\archivo.txt""/cid:45 423 /z:65 /a:23 /m:39 /t:45rt " Check that the end of the file is follow by "/cid:45" whitchs makes de patter invalid, but insted of getting a mgetfile.count = 0 the program is block, if i make a debug I got a property evaluation failed. Thanks for your comments !!!

  • How to protect HtmlHelper code in MVC controls

    - by Oats
    I am writing a custom mvc control (commercial), and all of the control's code lives in the custom htmlhelper code that i will have to distribute to the user. I am ok with this for my commercial license sale, but for evaluating the controls, if i give out the htmlhelper code locally for my potential customers to evaluate, the user can simply "get" all the code and hence he may never buy it since he's got teh control code. How do i protect my htmlhelper code while somebody is evaluation my cusotm mvc controls? Is this a general problem or (I wish) i am missing something here? Thanks.

  • Help using Lisp debugger

    - by Joel
    I'm trying understand how to interpret the output of, and use, the Lisp debugger. I've got a pretty simple Backtrace for the evaluation of my function, but I cann't seem to work out how to use it to find out in which Lisp 'form' in my function the exception occurred. I'd appreciate any clues as to what I should be doing, to find the source of the error. I've attached a screen shot (if it's too small to read I can re-post it in parts), with the debug output, the function and the repl (please ignore my very wrong function, I'm just interested in learning how to use the debugger properly). In addition, I hit 'v' on the first frame to go to the source, but this resulted in the error at the bottom of the screen.

To do: - implement factory method pattern - implement observer pattern - implement strategy pattern - implement visitor pattern The evaluation will depend on the number of added patterns and places they have been added. Am I an idiot or this is the stupidies possible assignement ? If not, please help me with some basic tips.. which one where ? Best Regards. P.S. Sorry for my English

  • What is the best method of assessment for computer science students?

    - by Gavimoss
    This question is a bit more philosophical so feel free to remove if you like but it's been bugging me for the last 4 years! As a final year student I find that exams can be often be passed with a couple of days of cramming, without necessarily retaining or understanding the content i.e. a regurgitation of lecture notes is often enough to gain high marks. A friend of mine is about to graduate with an honours degree whose final year evaluation was based solely on practical work (a project, assignment marks and the creation of a poster) yet all of this work could have been completed by a third party. Personally I don't think either of these methods of assessment is sufficient as I am currently on track for a 1st class honours in artificial intelligence and computer science and believe this is mostly due to my skill in passing exams not my skill as a programmer or my vast in depth knowledge of any of the subjects I have "studied". Surely there is a better way to assess our skills - isn't there?

  • Bug in Programming Interviews Exposed?

    - by Sam
    Hi, I could not find an errata for the 2nd edition of this book. My question concerns the if-statement in the following piece of code. void removeHead (Node ** head) { Node * temp; if (!(*head)) { temp = (*head)->next; delete *head; *head = temp; } } So I understand that the point of the if-statement is to check if the Node is null. However by adding an additional "!" to the evaluation, wouldn't this negate the false value of null? Would it be correct to change it to something like: if (*head) { ... } Also if anyone knows where I can find an official errata for the 2nd edition that would be great. Thanks, Sam

  • Writing an Eval Procedure in Scheme?

    - by Planeman
    My problem isn't with the built-in eval procedure but how to create a simplistic version of it. Just for starters I would like to be able to take this in '(+ 1 2) and have it evaluate the expression + where the quote usually takes off the evaluation. I have been thinking about this and found a couple things that might be useful: Unquote: , (quasiquote) (apply) My main problem is regaining the value of + as a procedure and not a symbol. Once I get that I think I should just be able to use it with the other contents of the list. Any tips or guidance would be much appreciated.

  • What are real-world examples of Gradle's dependency graph?

    - by Michael Easter
    As noted in the documentation, Gradle uses a directed acyclic graph (DAG) to build a dependency graph. From my understanding, having separate cycles for evaluation and execution is a major feature for a build tool. e.g. The Gradle doc states that this enables some features that would otherwise be impossible. I'm interested in real-world examples that illustrate the power of this feature. What are some use-cases for which a dependency graph is important? I'm especially interested in personal stories from the field, whether with Gradle or a similarly equipped tool. I am making this 'community wiki' from the outset, as it will be difficult to assess a 'correct' answer.

  • Strategy for desugaring Haskell

    - by luqui
    I'm developing a virtual machine for purely functional programs, and I would like to be able to test and use the the wide variety of Haskell modules already available. The VM takes as input essentially terms in the untyped lambda calculus. I'm wondering what would be a good way to extract such a representation from modern Haskell modules (eg. with MPTC's, pattern guards, etc.). I did a little research and there doesn't seem to be a tool that does this already (I would be delighted to be mistaken), and that's okay. I'm looking for an approach. GHC Core seems too operationally focused, especially since one of the things the VM does is to change the evaluation order significantly. Are there any accessible intermediate representations that correspond more closely to the lambda calculus?

  • How can I evaluate a deferred Linq statement when debugging?

    - by DanO
    I'm debugging in VS2010, and I want to inspect a string value but all I can get the debugger to show me (through watches, hovering, locals, etc.) is: "System.Linq.Enumerable+<TakeIterator>d__3a`1[System.Char]" I don't care if there are side effects from premature evaluation or whatever, I just want to see what the expression would evaluate to if I evaluate it right now at the current breakpoint. How is this done? Also can I change my code in such a way that it evaluates earlier? Not that I care when I'm not debugging... but just wondering. In case it is relevant... (I doubt it.) I'm stuffing a new entity object before saving it to the database... some fields are assigned with LINQ statements, I'm not sure when they get evaluated under the covers of EF. The DB update fails with 'string or binary data would be truncated... So I'm trying to find the too-long field.
