• Code generation tool, to create C# adapter classes for unit testing?

  - by RyBolt

  I know I wouldn't need this with Typemock, however, with something like MoQ , I need to use the adapter pattern to enable the creation of mocks via interfaces for code I don't control. For example, TcpClient is a .NET class, so I use adapter pattern to enable mocking of this object, b/c I need an interface of that class. I then produce interface ITcpClient, that can then be implemented via a TcpClientAdapter class, which is just plain vanilla adapter pattern implementation. I am looking for a tool to do this automatically (creation of interface and adapter), I would think there is one out there somewhere? (or is everyone just hand coding these)

• looping and arrays

  - by user1838418

  Hi I'm trying to construct a loop to execute 16 states of the 8 4 2 1 code in (C++) while( condition) { double Bubble[16], Bubble1[16]; Bubble[0] = ( a-2 - (b-2) ) + ( c-2 - (d-2)); // represents 0000 Bubble[1] = ( a-2 - (b-2) ) + ( c-2 - (d+2)); // represents 0001 Bubble[2] = ( a-2 - (b-2) ) + ( c+2 - (d-2)); // represents 0010 Bubble[3] = ( a-2 - (b-2) ) + ( c+2 - (d+2)); //represents 0011 ....... Bubble[15] =(a+2 - (b+2) ) + ( c+2 - (d+2)); //represents 1111 } Is there an easy way of coding using for loops? instead of writing bubble[] every time? 0 stands for -2 and 1 stands for +2. So I have 4 variables and each one need to be incremented and/or decremented. Can this be done using for loop? Appreciate your help

• const ready only local copies

  - by robUK

  Hello gcc 4.4.4 c89 I am just wondering is it worth passing a const into a function. i.e. void do_something(const char *dest, const int size) The size is a ready-only so I don't want to change it. However, some developers never have this as const has it is a local copy that is being used. The pointer is const as you can change the value in the calling routine. I always have a const on ready-only local copies, as it confirms to anyone reading my code that it is a ready-only variable. And also, when coding I don't make the mistake of changing it without realizing. Many thanks for any suggestions,

• Filling in a form client-side [Javascript]

  - by Hawker

  I'm coding up a small Vista/7 sidebar gadget for our web based employee schedule system and I've run into a Javascript problem that my Google-FU can't solve. I can't figure out how to fill in a login form from the client. I'm creating a new ActiveXObject, navigating to the site, but lost as to where to go from here. var conn = new ActiveXObject("Microsoft.XMLHTTP"); conn.open("POST", "url", false); conn.send(null); Can access the form from the ActiveXObject based on the form id? I'd also assume I'm going to need to change a few headers for a POST vs. a GET? Thanks for any tips or links to references! I can't seem to find much and JavaScript isn't my forte.

• php script to generate checksum from md5

  - by sumit

  In order to calculate the checksum i need following things. these parameters are concatenated in a constant (no spaces) string made up of the values of the following parameters in the exact order listed below: o Secret Key o Merchant id o Currency o Total amount o Item list (item_name_1, Item_amount_1, item_quantity_1 to item_name_N, Item_amount_N, item_quantity_N) o Timestamp e.g In that case the string befor hash will be: pLAZdfhdfdNh57583USD69.99Tier2 item69.9912010-06-14.14:34:33 And using the MD5 hash function the result is: ghvsaf764t3w784tbjkegbjhdbgf i want to know how can i create a php script that will call md5 hash function with the inputs given above and based on that it will generate the hash function value that will be the checksum value for my coding..

• App crashing on open on Motorola Backflip only

  - by anakin78z

  I have recently published my second app on the Android Market. I've gotten a few e-mails about the app crashing on open, and all users were using the Motorola Backflip. It seems to work fine on all other devices. The app shows the background image, but crashes right after that. Is there something different I have to do when coding for that device? The strange thing is that it is very similar to my first app, which seems to work just fine for them. The major difference is that my second app is a paid app, and uses Android Licence Verification. My implementation should catch any license errors though, and I've tested this on my device. Users have uninstalled and reinstalled the app without success. I'm stumped. The other thing they're reporting is that the icon doesn't even show properly, but rather is a gear in a box, which makes me think that something goes awry very early in the installation process.

• jquery issues - it wont change it accordingly

  - by chuck

  My coding isnt linking properly , its meant to use jquery to detect the OS and change the link accordingly , however it isn't. In my HTML page I have it linked in the header as <script src="jsquery.js" type="text/javascript"></script> which loads up my jsquery now $(document).ready(function() { if (navigator.appVersion.indexOf("Win") != -1) { // Computers runs windows $("a[href$='.pdf']").each(function() { this.href = this.href.replace("Volumes", "KP01DS0194TG"); }); } if (navigator.appVersion.indexOf("Mac") != -1) { // computer is a Mac $("a[href$='.pdf']").each(function() { this.href = this.href.replace("KP01DS0194TG", "Volumes"); }); } }); Yet on Mac's it still tries to connect to KP01DS0194TG and not to Volumes - it doesnt change it - how can I get it to recognize the OS and change it accordingly?

• PHP Datediff days involved

  - by user3549835

  I need to know how many days are involved in a date diff. \For example: <? $start = new DateTime('2014-06-29 14:00:00'); $ende = new DateTime('2014-07-02 05:45:00'); $diff = $start->diff($ende); echo $diff->format('%R'); echo $diff->days; ?> The above code echos +2 My desired result would be 4, because the 29th, 30th, 1st and 2nd of July are "touched". I have no idea to achieve that with the given functions. Coding a day-subtraction seems to bean open door for errors.

• How to Audit Database Activity without Performance and Scalability Issues?

  - by GotoError

  I have a need to do auditing all database activity regardless of whether it came from application or someone issuing some sql via other means. So the auditing must be done at the database level. The database in question is Oracle. I looked at doing it via Triggers and also via something called Fine Grained Auditing that Oracle provides. In both cases, we turned on auditing on specific tables and specific columns. However, we found that Performance really sucks when we use either of these methods. Since auditing is an absolute must due to regulations placed around data privacy, I am wondering what is best way to do this without significant performance degradations. If someone has Oracle specific experience with this, it will be helpful but if not just general practices around database activity auditing will be okay as well.

• Archiving rows dynamically

  - by Serge

  I was wondering what would be the best solution to dynamically archive rows. For instance when a user marks a task as completed, that task needs to be archived yet still accessible. What would be the best practices for achieving this? Should I just leave it all in the same table and leave out completed tasks from the queries? I'm afraid that over time the table will become huge (1,000,000 rows in a year or less). Or should I create another table ie task_archive and query that row whenever data is needed from it? I know similar questions have been asked before but most of them where about archiving thousands of rows simultaneously, I just need to know what would be the best method (and why) to archive 1 row at a time once it's been marked completed

• html links & hover events over certain locations on an image.

  - by Tommy

  So i created a web site a long time ago using a designer alot like frontpage + expression design put together, and since then Ive gotten more into coding, and I'm learning html, CSS, and all that good stuff.. and i have this re-designed header that Ive made here: http://prntscr.com/8zct So what I need to know, is how i can get it so that when a user clicks on one of the links in the header design it will redirect to a page. and also if possible, how to make it so when a user hovers over a link a drop down may appear with other options. As me being quite new to this sort of stuff, could anybody help me achieve this? PS. I'm working in Visual Studio with ASP. but that doesn't change anything about the html and css stuff. just letting you guys know.

• How to merge or copy anonymous session data into user data when user logs in?

  - by benhoyt

  This is a general question, or perhaps a request for pointers to other open source projects to look at: I'm wondering how people merge an anonymous user's session data into the authenticated user data when a user logs in. For example, someone is browsing around your websites saving various items as favourites. He's not logged in, so they're saved to an anonymous user's data. Then he logs in, and we need to merge all that data into their (possibly existing) user data. Is this done different ways in an ad-hoc fashion for different applications? Or are there some best practices or other projects people can direct me to?

• Scripting vim to Run Perltidy on a Buffer

  - by rjray

  At my current job, we have coding-style standards that are different from the ones I normally follow. Fortunately, we have a canned RC file for perltidy that I can apply to reformat files before I submit them to our review process. I have code for emacs that I use to run a command over a buffer and replace the buffer with the output, which I have adapted for this. But I sometimes alternate between emacs and vim, and would like to have the same capabilities there. I'm sure that this or something similar is simple and had been done and re-done many times over. But I've not had much luck finding any examples of vim-script that seem to do what I need. Which is, in essence, to be able to hit a key combo (like Ctrl-F6, what I use in emacs) and have the buffer be reformatted in-place by perltidy. While I'm a comfortable vim-user, I'm completely clueless at writing this sort of thing for vim.

• Web Designer looking to learn back-end programming...

  - by Tabetha Moe

  Hello, my name is Tabetha and I have a question... I am a web designer, but I always find that while designing the layout and coding the design I come up with great ideas for websites. I would like to know where I need to start in order to learn back-end programming not only for the knowledge, but also for the challenge of it. I have searched online but can't seem to find the information I am looking for. If anyone can give me a simple, straight-forward "this is what language you need to learn" answer, or perhaps guide me in the right direction I would appreciate it ten-fold. I am a complete noob when it comes to this, so even the most basic information is probably a pearl of wisdom for me. :)

• jQuery model-view-controller vs Spring MVC

  - by user1515968

  my question is what potential problems or difficulties would be with implementing usual web app with somewhat reach user interface (multiple dynamic tabs, accordians and so on) using jQuery MVC approach with Spring REST vs using Spring MVC. Problems what I can think of could be: I will not be able to use Spring security fully, JavaScript coding could become hard to manage, any form verification becomes not easy to manage... what else? and does jQuery MVC with REST make sense at all? On other side jQuery with MVC and REST move all GUI concerns to JavaScript side (whether it is bad or not) and leave all data manipulation to server side.

• 'An error occurred. Please try later' message on Facebook authentication dialog

  - by Eugene Zhuang

  I am a newbie who is trying to create a Facebook app using PHP and Facebook's PHP SDK. The app is hosted on Heroku, and the sample app that they provided is working fine. However, I am now trying to get the sample app to work on Apache 2.2, and I have encountered a lot of problems along the way. Well, straight to the point, my latest problem will be trying to do Facebook login on localhost, but the 'An error occurred. Please try later' appears on the popup dialog. This does not happen on Heroku. Will someone please enlighten me on if there's any steps that I can take to overcome this error? I don't think it got to do with any coding error since I am just following the provided sample app. Thanks!

  I know this is may not be the right place to ask this sort of question,,on the other hand i am sure that it maybe the best...as many of you own a startup.

• Deploying locally compiled binaries on server

  - by nano

  Hi, I have a Zen based VPS server that runs on a dual-core AMD Opteron 64-bit machine. I have some locally developed C++ based daemons that I would want to deploy in that machine. My local machine is an Intel core 2 duo laptop. Can I execute binaries compiled from source code on my machine directly on the above mentioned server? I am a newbie in this area. Would be great if someone could throw light on the standard practices in this kind of situation. Thanks in advance

• Best practice for autoupdates

  - by ravi

  For desktop based applications, what are best practices to perform auto updates? Currently, we download all files, then copy and register (if com dll) to their respective directories. I looked at Google Chrome update method. It seems that it first downloads a zipped file into a directory, and then unzips all the files. Also, they have a setup application which seems to be used to do the update. Additionally, they create a directory mapped to update version like 1.0.154.43, but they keep the old version's directory.

• Which is the future of web development: HTML5 or Silverlight(or other RIA framework)?

  - by Morgan Cheng

  My colleagues have a heated debate on what is the future of web development. One side is supporting HTML5 and the other is supporting Silverlight. There is no conclusion of the debate yet. In my humble opinion as a programmer, HTML5 will not improve programming productivity, while Silverlight will. In my understanding, programmers still need to program in JavaScript to take advantage of HTML5. For Silverlight, we can use C# which is static-type language. A lot of coding defects can be found in compilation time. For HTML5, different browsers might still have different behavior even though there is spec. For Silverlight, generally what works in IE will work the same way in other browsers. Just my thoughts. Any idea on how to choose future direction of web development?

• Starting out with Exchange Server development

  - by Tony

  Hi, We've written several Outlook Add-ins for various projects and have now been asked to look at writing a Exchange server add-in. We will need to inspect all incoming / outgoing msgs and tag / file them into a document management system. If it's a message that we are interested in we would ideally like to change the default icon that is displayed in Outlook. We could I guess settle for Categorising / colour coding the email but we've been asked for a icon. Any guidance on how to get started / killer reference apps much appricaiated. Oh we will be needing to target both Exchange 2003 and 2007. vb.net is our bag but were fine with c# too. Thanks in advance - liking the site thus far btw

• Preparing for the next C++ standard

  - by Neil Butterworth

  The spate of questions regarding BOOST_FOREACH prompts me to ask users of the Boost library what (if anything) they are doing to prepare their code for portability to the proposed new C++ standard (aka C++0x). For example, do you write code like this if you use shared_ptr: #ifdef CPPOX #include <memory> #else #include "boost/shared_ptr.hpp" #endif There is also the namespace issue - in the future, shared_ptr will be part of the std, namespace - how do you deal with that? I'm interested in these questions because I've decided to bite the bullet and start learning boost seriously, and I'd like to use best practices in my code. Not exactly a flood of answers - does this mean it's a non-issue? Anyway, thanks to those that replied; I'm accepting jalfs answer because I like being advised to do nothing!
