• Any way to surround code block with Curly Braces {} in VS2008?

  - by Jim McKeeth

  I always find myself needing to enclose a block of code in curly braces { }, but unfortunately that isn't included in the C# surround code snippets, which seems to be an oversight. I couldn't find anything on building your own surround snippets either (just other kinds of snippets). I am actually running Resharper too, but it doesn't seem to have this functionality either (or I haven't figured how to activate it). We have a coding standard of including even a single line of code after an if or else in curly braces, so if I could just make Resharper do that refactor automatically that would be even better!

• bulk update/delete entities of different kind in db.run_in_transaction

  - by Ray Yun

  Here goes pseudo code of bulk update/delete entities of different kind in single transaction. Note that Album and Song entities have AlbumGroup as root entity. class AlbumGroup: pass class Album: group = db.ReferenceProperty(reference_class=AlbumGroup,collection_name="albums") class Song: album = db.ReferenceProperty(reference_class=Album,collection_name="songs") def bulk_update_album_group(album_group): updated = [album_group] deleted = [] for album in album_group.albums: updated.append(album) for song in album.songs: if song.is_updated: updated.append(song) if song.is_deleted: deleted.append(song) db.put(updated) db.delete(deleted) a = AlbumGroup.all().filter("...").get() # bulk update/delete album group. for simplicity, album cannot be deleted. db.run_in_transaction(bulk_update_album_group,a) But I met a famous "Only Ancestor Queries in Transactions" error at the iterating reference properties like album.songs or album_group.albums. I guess ancestor() filter does not help because those entities are modified in memory. Should I not to iterate reference property in transaction function and always provide them as function parameters like def bulk_update_album_group(updated,deleted): ??? Is there any good coding pattern for this situation?

• Sending object C from class A to class B

  - by user278618

  Hi, I can't figure out how to design classes in my system. In classA I create object selenium (it simulates user actions at website). In this ClassA I create another objects like SearchScreen, Payment_Screen and Summary_Screen. # -*- coding: utf-8 -*- from selenium import selenium import unittest, time, re class OurSiteTestCases(unittest.TestCase): def setUp(self): self.verificationErrors = [] self.selenium = selenium("localhost", 5555, "*chrome", "http://www.someaddress.com/") time.sleep(5) self.selenium.start() def test_buy_coffee(self): sel = self.selenium sel.open('/') sel.window_maximize() search_screen=SearchScreen(self.selenium) search_screen.choose('lavazza') payment_screen=PaymentScreen(self.selenium) payment_screen.fill_test_data() summary_screen=SummaryScreen(selenium) summary_screen.accept() def tearDown(self): self.selenium.stop() self.assertEqual([], self.verificationErrors) if __name__ == "__main__": unittest.main() It's example SearchScreen module: class SearchScreen: def __init__(self,selenium): self.selenium=selenium def search(self): self.selenium.click('css=button.search') I want to know if there is anything ok with a design of those classes?

• Updating display of elements on the web page without refreshing the whole page

  - by ivorossi3

  Last time I coded a web application was almost 10 years ago. I used Java/JSP/HTML/CSS etc. I've been coding non-web applications only ever since. When I look at modern sites now (like this one), I realize how my web development skills are obsolete. Maybe the most obvious "feature" that I wouldn't know how to implement now is the update of elements on the page after user input without having to refresh the whole page (e.g. the voting/downvoting here updates the vote count without reloading the whole page). What are the basic technologies behind this?

• new with exception with Microsoft

  - by wsd

  As I'm coding for both Windows and Linux, I have a whole host of problems. Microsoft Visual C++ has no stdint header, but for that I wrote my own. Now I found out that MS C++'s new operator does not throw an exception, so I want to fix this a quickly as possible. I know I can define a Macro with Parameters in Parenthesis, can I define a macro that replaces MyClass x = new MyClass(); with #ifdef MSC_VER if(!(MyClass x = new MyClass()) { throw new std::bad_alloc(); } #else MyClass x = new MyClass(); #endif (or something equivalent), AND works in BOTH MS C++ and G++ ? Or alternatively if that is not possible, a batch file to run over the Code to do this? I have become rather dependent on this exception being thrown.

• .NET Framework - When to Upgrade?

  - by Andrew

  I’m faced with a challenge of leading two (currently) separate .NET development groups with different development strategies. One group is developing on the .NET Framework 2.0 (with maybe a few applications on 3.5). The other group immediately adopts any new framework that comes out, and begins coding any new applications with it (they are running 2.0-4.0 applications). For this last group, applications written in an earlier version than the latest framework do not get upgraded. What is the current school of thought when it comes to a company developing web applications on when to adopt a new framework, and whether to migrate applications built on previous versions to the latest framework or not? Years ago the thought was to wait until the technology became mainstream - but that doesn't seem to apply much now with .NET.

• Run java with highest security setting

  - by Ankiov Spetsnaz

  I'm currently writing an in house coding challenge web application and I am wondering if there is any other security precaution I would need to have other than below java option at runtime. java -Djava.security.manager=default Basically, challenges would be more of single threaded math and algorithm focused. So I would need to enable basic data structure objects and disable any file, sockets, threading or any thing that might be not so important. Based on my quick search turning on security manager as above seems to be a solution but since this is a security related I would like to be sure before it goes alive. Is there anything else I could do more?

• How to double the size of 8x8 Grid whilst keeping the relative position of certain tiles intact?

  - by ke3pup

  Hi guys I have grid size of size 8x8 , total of 64 Tiles. i'm using this Grid to implement java search algorithms such as BFS and DFS. The Grid has given forbidden Tiles (meaning they can't be traversed or be neighbour of any other tile) and Goal and Start tile. for example Tile 19,20,21,22 and 35, 39 are forbidden and 14 an 43 are the Goal and start node when the program runs. My question is , How can i double the size of the grid, to 16x16 whilst keeping the Relative position of forbidden tiles as well as the Relative position of start and goal Tiles intact? On paper i know i can do this by adding 4 rows and columns to all size but in coding terms i don't know how to make it work? Can someone please give any sort of hints?

• Object-oriented Programming - need your help

  - by wanderameise

  hey folks, I try to realize a little game project to dive deeper into OO programming (winforms c++/cli). I already started coding but now I´d like to make a re-design. For the beginning the game should consist of four parts like game-engine, user interface, highscore and playground. Heres a little (non-UML-conform) class diagramm to visualize my purposes http://i.imgur.com/lmpwj.png Would this be the right way? In my eyes the game engine is responsible to control the game sequences (state machine?) and exchanges information betweens all other classes. I appreciate any help!

• How do i translate this to "simpler" JavaScript?

  - by Julian Weimer

  Since i'm working with Titanium i realzed that its current JavaScript Interpreter doesn't accept specific coding-styles. So for for-loops and if-statements i have to have braces, even though i only want to span one line. Furthermore there is more i have to change if i want to use a Javascript Library like underscore.js. This is what Titanium doesn't want to see: if (!(result = result && iterator.call(context, value, index, list))) {_.breakLoop();} if (nativeSome && obj.some === nativeSome) {return obj.some(iterator, context);} var computed = iterator ? iterator.call(context, value, index, list) : value; computed >= result.computed && (result = {value : value, computed : computed}); Can i use a simpler syntax to describe the logic behind those lines of code?

• How can I clean up this SELECT query?

  - by Cruachan

  I'm running PHP 5 and MySQL 5 on a dedicated server (Ubuntu Server 8.10) with full root access. I'm cleaning up some LAMP code I've inherited and I've a large number of SQL selects with this type of construct: SELECT ... FROM table WHERE LCASE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE( strSomeField, ' ', '-'), ',', ''), '/', '-'), '&', ''), '+', '') ) = $somevalue Ignoring the fact that the database should never have been constructed to require such a select in the first place, and the $somevalue field will need to be parameterised to plug the gaping security hole, what is my best option for fixing the WHERE condition into something less offensive? If I was using MSSQL or Oracle I'd simply put together a user-defined function, but my experience with MySQL is more limited and I've not constructed a UDF with it before, although I'm happy coding C. Update: For all those who've already raised their eyebrows at this in the original code, $somevalue is actually something like $GET['product']—there are a few variations on the theme. In this case the select is pulling the product back from the database by product name—after stripping out characters so it matches what could be previously passed as a URI parameter.

• How to split page and reveal stuff underneath?

  - by sudo rm -rf

  Hi there. I've already achieved this on my iPhone app, but I want to know if it's possible on an HTML page, maybe using CSS effects or similar. As you can see, the current view is split, the bottom part is moved down, and another view is revealed underneath. I have a page I'd like to try this on. Any ideas if this is possible, and any specifics as to how I can do it? I'm quite new to HTML coding, so please take it easy on me. :) Thanks in advance!

• How to implement B+ Tree for file systems ?

  - by user312544

  I have a text file which contains some info on extents about all the files in the file system, like below C:\Program Files\abcd.txt 12345 100 23456 200 C:\Program Files\bcde.txt 56789 50 26746 300 ... Now i have another binary which tries to find out about extents for all the files. Now currently i am using linear search to find extent info for the files in the above mentioned text file. This is a time consuming process. Is there a better way of coding this ? Like Implementing any good data structure like BTree. If B+ Tree is used what is the key, branch factor i need to use ?

• Best way to implement symfony admin components

  - by Chris T

  I am coding a backend in symfony using the sfThemePlugin (part of sympal). The dashboard should allow for new "admin plugins" to be added fairly easily. What I'd like is to have a config.yml config like this: sf_easy_admin_plugin: enabled_admin_dashboard_plugins: [Twitter, QuickBlogPost, QuickConfig] and when these are set it includes the correct components into the template. I'd like to have each one be in it's own plugin (sfTwitterEasyAdminModule, sfQuickBlogPostEasyAdminModule) or have them all bundled in one (sfEasyAdminModules). Is there anyway to accomplish this? As far I know symfonys include_component() only let's you include components from the current module and not from other plugins. Each "component" or admin plugin should render an icon for the dashboard and a html form that will be hidden until the user clicks the icon.

• How to create an image from array of pixel colors? (Flash, Actionscript 3)

  - by Ole Jak

  I have a Width and Height parametr. I have been given an array of colors in such format: [r, g, b, a, r, g, b, a, r, g, b, a... etc] Data can be acsessed by something like this for(var y = 0; y < height; y++) { for(var x = 0; x < width; x++) { r = data[y*width + x + 0] g = data[y*width + x + 1] b = data[y*width + x + 2] a = data[y*width + x + 3] } } I want to paint that data on some sprite. How to do such thing? BTW: I use Flash Builder for mxml+actionscript coding. So if it is easy for you you can give example using MXML (not todraw on some sprite but on some MXML component).

• Where does one enter the JavaScript code in CRM Dynamics?

  - by Konrad Viltersten

  I've started to play with CRM Dynamics yesterday so this question should be seen as a very basic one. I've been coding for many years but CRM D is news to me. Apparently, one is supposed to be able to enter JavaScript code to customize the behavior of the application. I've understood that there's an API for that and that touching DOM directly or playing with jQuery is a no-no. Question: Where is the JS-code supposed to be entered? I've gone through all the menus but as far I can see, there's no spot where I could plug-in my custom code. E.g.: Where do I get to define a validation for the last name of a contact currently being defined?

• Why is 'virtual' optional for overridden methods in derived classes?

  - by squelart

  When a method is declared as virtual in a class, its overrides in derived classes are automatically considered virtual as well, and the C++ language makes this keyword virtual optional in this case: class Base { virtual void f(); }; class Derived : public Base { void f(); // 'virtual' is optional but implied. }; My question is: What is the rationale for making virtual optional? I know that it is not absolutely necessary for the compiler to be told that, but I would think that developers would benefit if such a constraint was enforced by the compiler. E.g., sometimes when I read others' code I wonder if a method is virtual and I have to track down its superclasses to determine that. And some coding standards (Google) make it a 'must' to put the virtual keyword in all subclasses.

• Are there any good books on writing commercial quality software?

  - by Andy

  Hey, My background has been generally new technology demonstrators, which, well... demonstrate the latest technology and how it can be of use to a clients company. They use it for internal demos etc. Now my career has shiffed course a bit more into actual products, in particular software which runs in locations like museums as interactive pieces. Clearly, although the technology demonstrators had to be well coded etc, there wasn't as much emphasis as there is on my current work, which has to work, be highly configurable, probably multi-ligual and run constantly, without restarts. So my question is, now that I'm trying to up my coding quality and write more commercial applications, are there any books which discuss issues surrounding high quality commercial software? I currently have a copy of Code Complete 2nd Edition, which is excellent, but just wondering if there's any better, possibly more focused titles out there? Thanks a lot! Andy.

• How to structure web application with part of it being secured (SSL)

  - by spirytus

  What is the common pattern to structure web application where part of it has to be secured. So lets say I have page_a and page_b which do not need to be secured, although should display login information (login fields or login details once user logged in). This web app. also would have secured pages (admin, checkout or similar) secure_page_c and secure_page_d. My questions are: What is the common folder structure for such assuming I code in php with no frameworks? Also how shall I deal with session variables in case user navigates lets say from secure_page_b to non secure page_a or vice versa? What else might be a problem and should be considered when coding that kind of app in php? Thank you all for any suggestions

• Is there a semantic difference <span>'s and <div>'s?

  - by DavidR

  I know when coding HTML, I'm supposed to keep semantics in mind, e.g., h1 needs to be a main header, h2 needs to be a subheader, tables need to be tables, use <em> for emphasis instead of <i>, etc. Is there a proper difference between divs and spans except one is a block and the other is in-line? When I was learning I was told that <span>'s were for styling text mid-line. If I had a small blurb of text that I needed positioned at a certain point in my webpage, one that doesn't warrent a <p> tag, would I use a span should I stick with div's? What if that text needs to cover two lines (i.e., it needs a width) if it contains nothing but text, what should I use?

• Three Java classes: point out all the issues you can find!

  - by Sicarius

  I wrote three classes for a colleague of mine (I'm new at this job). They compile just fine, but he tells me there are "defects, bugs, and style problems." He wants me to print the files out and mark the problems such as the standard coding conventions, best practices, format, design, and logic. I wrote this code when I was extremely tired and I plan to rewrite it completely. My mistake was showing to it before looking it over myself again. However, he still wants me to do the markings on paper. Any input is greatly appreciated! The three Java classes ['Station.java', 'ParserInt.java', 'ParserException.java'] are uploaded here: http://www.megaupload.com/?d=N2CUVSV2

• How to debug this?

  - by LeonixSolutions

  I have an application which takes measurements every second (I am running it in demo mode & generating random data, so the problem is not to do with reading from devices attached to the serial port). After 5 or 6 minutes it hangs. I have added try // entire body of procedure/function goes here except on E: Exception do begin MessageDlg('Internal coding error in <function name>()', mtError, [mbOK], 0); end; end; to every single function (and Application.Run() in the project file), but I don't see any message dialogs. Any idea how I can test this?
