• 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?

• gdb: SIGTRAP on std::string::c_str() call

  - by sheepsimulator

  So I've been trying to use gdb to return the value of a string I have by calling > print <member variable name>.c_str() But everytime I do so, I get this: Program received signal SIGTRAP, Trace/breakpoint trap. <some address> in std::string::c_str() from /usr/lib/libstdc++.so.6 GDB remains in the frame where the signal was received. To change this behavior use "set unwindonsignal on" Evaluation of the expression containing the function (std::string::c_str() const) will be abandoned. Two questions: Why/how is the standard library throwing SIGTRAP? I checked basic_string.h and c_str() is defined as: const _CharT* c_str() const { return _M_data(); } I don't see any SIGTRAP-throwing here... is there a way to get around this SIGTRAP? How can I read the text value of the std::string out (without getting some crazy extension library) in gdb?

• 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.

• Windows Phone 7 Design Template

  Windows Phone 7 Design Template Expression Blend is a wonderful design environment for WP7 (Windows Phone 7) but for quickly visualizing a concept nothing beats Illustrator! I am excited about WP7 and decided that having a solid .ai template would prove invaluable. Some of the details of the WP7 UI Design and Interaction Guide are a bit fuzzy (literally) but I was able to generate some useful layout guides, character styles, and symbols. While the template does not cover every aspect of the guide I think it is a good launching point; if you find it useful and extend it please share your updates (I created the template in CS4, if you have problems in earlier versions let me know).Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Expressions that are idiomatic in one language but not used or impossible in another

  - by Tungsten

  I often find myself working in unfamiliar languages. I like to read code written by others and then jump in and write something myself before going back and learning the corners of each language. To speed up this process, it really helps to know a few of the idioms you'll encounter ahead of time. Some of these, I've found are fairly unique. In Python you might do something like this: '\n'.join(listOfThings) Not all languages allow you to call methods on string literals like this. In C, you can write a loop like this: int i = 50; while(i--) { /* do something 50 times */ } C lets you decrement in the loop condition expression. Most more modern languages disallow this. Do you have any other good examples? I'm interested in often used constructions not odd corner cases.

• 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

• Add rules (filters) to ftp programs to avoid uploading certain files/folders

  - by guisasso

  i use Filezilla as my ftp client, but this question goes to any other client that could be useful. Can i (in any client) add rules (filters) to an ftp program to avoid upload of certain files or folders? For example: Expression web creates those annoying _vti_cnf folders, or, certain folders in which i have the original version of a picture without a watermark that i don't want to upload. Example, i have a folder A, that has sub folders "original" and "current", i would like to add a filter, so every time i select A to be uploaded, "original" wouldn't go, but "current would".

• Google Analytics: Why does "/" appear in goal funnel visualization?

  - by Lauren

  This is the goal funnel for checkout. Does anyone have any idea where the "/" is coming from? The cart page is at site: game on glove dot com (I don't want this stackoverflow page being indexed in google particularly well). Go to the site, click on the order button, make your selection, and click the button to enter the cart (it resolves to /Cart and /Shop-Cart). I believe I used the regular expression matching to match "cart". So why the "/" (I don't know what is causing the home page to reload when users are on the Cart page within a Colorbox lightbox where the only way back to home or "/" is to hit the exit button in the top right of the lightbox)? Here's my one guess for the former question but it doesn't seem likely: See the "check out with paypal" button? If you hovered over it, it does default to the home page which is what might be the "/"... but it really redirects the user to the paypal.com page so it shouldn't also load the home page.

  Google : « ne plus être soumis à la loi des États-Unis, ce serait génial » Son co-fondateur critique Facebook et Apple et se dit « plus inquiet que jamais » pour l'ouverture d'Internet « La liberté sur Internet est en danger ». Cette déclaration alarmiste ne vient pas du Parti Pirate ou de l'Electronic Frontier Foundation mais d'un acteur beaucoup plus étonnant : Sergey Brin, un des deux co-fondateurs de Google. Dans un entretien au quotidien britannique The Guardian, le jeune dirigeant (38 ans) s'en prend pêle-mêle aux gouvernements qui essayent de contrôler l'expression des citoyens, aux associations d'auteurs/compositeurs qui sous prétexte, d'après lui, de lutter c...

• Securing WinForms Application suggestions

  - by Sarah Fordington

  I've been looking for a simple key/license system for our users. Its partly to stop piracy (avoid users from sharing the application around) and the other half to track the number of 'licensed users' we have. I have already read a few good suggestions on SO but I'm curious as to how people have implemented the 30 day evaluation criteria. Do you generate a key that stores the date somewhere and do a comparison each time or is it a little more complicated - deleting the file/removing the registry shouldn't deactivate. Are there any example implementations out there that can give me a head start? The irony is that our PM doesn't want to license a third-party system to do it for us. This is for a Windows Forms application.

• Insert string from database into an aspx and have databinding expressions within that text evaluated

  - by Christopher Edwards

  Well, as you can see I want something quick-and-dirty! How can I get a string from a db that has aspx databinding syntax in it and have the databinding expressions evaluated? So I have text such as this stored in the DB:- Hello <%=User.Name %> I haven't seen you since <%=User.LastVisit %> And I want it to be inserted here say:- ... <body> <form id="form1" runat="server"> <div> <asp:FormView ID="FormView1" DataSourceID="DataSource1" runat="server"> <ItemTemplate> <-- insert stuff here! --> ... But with the databinding expressions evaluated. I'd rather not build a full parsing, templating and evaluation engine...

• 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.

• 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?

• 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?

• Choix technologique : Spring 3.0 ou Java EE 6 pour vos projets Java en 2010 ?

  Fin 2009, ce sont deux solutions très attendues qui ont finalement été livrées : D'un coté Spring 3.0, framework déjà fort utilisé en entreprise, et qui arrive avec quelques nouveautés : Support de Rest, Expression Language, .. Principal atout : Il est déjà utilisable sur des serveurs omniprésents en production (Tomcat, Websphere 6.1,..) De l'autre coté, Java EE 6. Un nouvelle version du standard, beaucoup plus légère et souple que les anciennes versions. Il propose également un profil Web, qui propose des fonctionnalités fort similaire à ce qui est proposé par Spring (EJB Lite, Injection de dépendances, ..). Pour l'heure, la seule implémentation disponible est Glassfish. De votre coté, quelle solution utilise...

• =~ (equal-sign tilde) and m" ... " in .htaccess directive

  - by Lèse majesté

  I saw this bit of code on an old forum post: SSLRequire %{HTTP_HOST} =~ m"\.secure\.powweb\.com" And I was just wondering what the =~ and m" ... " meant. I've been searching online and in the Apache documentation for any mention of the equal-sign tilde operator, but I've found no mention of it. I know that some directives can take a tilde to use a regular expression, but I've never seen the m" ... " form used before. What exactly is that m" ... " for? Where else would you see this form?

• 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.

Eps has a data type of double. Here's my code: var myData = myTable .Where(t => t.Comp.Equals("IBM") && Convert.Int32(string.Format("{0}{1}", t.Year, t.Quarter)) <= 20131); I get the following error when I tried that code: Method 'System.String Format(System.String, System.Object, System.Object)' has no supported translation to SQL How can I select all Eps that has a year & quarter less than "20132" using a lambda expression?
