• Most frustrating programming style you've encountered

  - by JaredPar

  When it comes to coding style I'm a pretty relaxed programmer. I'm not firmly dug into a particular coding style. I'd prefer a consistent overall style in a large code base but I'm not going to sweat every little detail of how the code is formatted. Still there are some coding styles that drive me crazy. No matter what I can't look at examples of these styles without reaching for a VIM buffer to "fix" the "problem". I can't help it. It's not even wrong, I just can't look at it for some reason. For instance the following comment style almost completely prevents me from actually being able to read the code. if (someConditional) // Comment goes here { other code } What's the most frustrating style you've encountered?

• When is it too late to go back to coding from a management role? [closed]

  - by LeoLambrettra

  Problem solving keeps the mind sharp and if you are like me then it makes you happy. But what if you went from coding up to Team Lead and then to Project Manager? I have a team of 12 and on a good salary but lately have been thinking that the politics and admin tasks of being middle level management in an Investment Bank is not the right path to happiness. I used to be able to design and code as well as manage but lately it's all budgets, admin tasks and people problems. At 39 is it too late to go be a senior developer again? Basically - Team Lead in a flat structure with good people rocks. But if half your team is offshore then it loses something - There's a lot of politics in Project Management and so many meetings that even if you want to code you start letting your team down by missing deadlines and only suited for small units of work The coding skills haven't gone so to pick up WCF services it just takes a bit of reading and then playing around. I reckon I could switch to a Hedge Fund and go back to developing and be far happier and get more money. My 2 doubts though are 1. Mid life crisis in that I'd get bored with coding again 2. Or maybe I'd like it but there aren't many dev jobs for 40+ so I'd be throwing away a high level management role that took 7 years at thee one bank to get to0 Anybody else made to switch back and survived?

• Arguments, local variables, and global variables in Python

  - by prosseek

  In python, there is no way to differentiate between arguments, local variables, and global variables. The easy way to do so might be have some coding convention such as Global variables start with _ and capital letter arguments end with with _ _Global variable = 10 def hello(x_, y_): z = x_ + y_ Is this a Pythonian way to go? I mean, is there well established/agreed coding-standards to differentiate them in python?

• Need for prefixing a function with (void)...

  - by puffadder

  Hi All, I recently came across a rather unusual coding convention wherein the call for a function returning "void" is prefixed with (void). e.g. (void) MyFunction(); Is it any different from the function call like: MyFunction(); Has it got any advantage or is it yet another needless but there coding convention of some sort?

• Why would var be a bad thing?

  - by Spoike

  I've been chatting with my colleagues the other day and heard that their coding standard explicitly forbids them to use the var keyword in C#. They had no idea why it was so and I've always found implicit declaration to be incredibly useful when coding. I've never had any problems finding out what type the variable was (you only hover over the variable in VS and you'll get the type that way). Does anyone know why it would be a bad idea to use the var keyword in C#?

• Return statements for all functions

  - by emddudley

  How common is it for coding style guidelines to include a requirement that all functions include a return statement (including functions which return void)? To avoid being subjective or argumentative, I'd like answers which can name specific companies or open-source projects which have this requirement. If you haven't ever come across this coding style guideline, or you have a resource (book, online article) which discusses it, that would be useful as well. Thanks!

• Are there any C++ style and/or standard example files available?

  - by Harvey

  While there are lots of questions about coding style, beautifying, and enforcement, I haven't found any example C++ files that are used as a quick reference for style. The file should be one or two pages long and exemplify a given coding standard/style. For example, the Google C++ Style Guide is a great reference, but I think a one to two page piece of code written in their style pinned to a wall would be more useful in day-to-day use. Do any of these already exist?

• Ignoring focusLost(), SWT.Verify, or other SWT listeners in Java code.

  - by Zoot

  Outside of the actual SWT listener, is there any way to ignore a listener via code? For example, I have a java program that implements SWT Text Widgets, and the widgets have: SWT.Verify listeners to filter out unwanted text input. ModifyListeners to wait for the correct number of valid input characters and automatically set focus (using setFocus())to the next valid field, skipping the other text widgets in the tab order. focusLost(FocusEvent) FocusListeners that wait for the loss of focus from the text widget to perform additional input verification and execute an SQL query based on the user input. The issue I run into is clearing the text widgets. One of the widgets has the format "####-##" (Four Numbers, a hyphen, then two numbers) and I have implemented this listener, which is a modified version of SWT Snippet Snippet179. The initial text for this text widget is " - " to provide visual feedback to the user as to the expected format. Only numbers are acceptable input, and the program automatically skips past the hyphen at the appropriate point. /* * This listener was adapted from the "verify input in a template (YYYY/MM/DD)" SWT Code * Snippet (also known as Snippet179), from the Snippets page of the SWT Project. * SWT Code Snippets can be found at: * http://www.eclipse.org/swt/snippets/ */ textBox.addListener(SWT.Verify, new Listener() { boolean ignore; public void handleEvent(Event e) { if (ignore) return; e.doit = false; StringBuffer buffer = new StringBuffer(e.text); char[] chars = new char[buffer.length()]; buffer.getChars(0, chars.length, chars, 0); if (e.character == '\b') { for (int i = e.start; i < e.end; i++) { switch (i) { case 0: /* [x]xxx-xx */ case 1: /* x[x]xx-xx */ case 2: /* xx[x]x-xx */ case 3: /* xxx[x]-xx */ case 5: /* xxxx-[x]x */ case 6: /* xxxx-x[x] */ { buffer.append(' '); break; } case 4: /* xxxx[-]xx */ { buffer.append('-'); break; } default: return; } } textBox.setSelection(e.start, e.start + buffer.length()); ignore = true; textBox.insert(buffer.toString()); ignore = false; textBox.setSelection(e.start, e.start); return; } int start = e.start; if (start > 6) return; int index = 0; for (int i = 0; i < chars.length; i++) { if (start + index == 4) { if (chars[i] == '-') { index++; continue; } buffer.insert(index++, '-'); } if (chars[i] < '0' || '9' < chars[i]) return; index++; } String newText = buffer.toString(); int length = newText.length(); textBox.setSelection(e.start, e.start + length); ignore = true; textBox.insert(newText); ignore = false; /* * After a valid key press, verifying if the input is completed * and passing the cursor to the next text box. */ if (7 == textBox.getCaretPosition()) { /* * Attempting to change the text after receiving a known valid input that has no results (0000-00). */ if ("0000-00".equals(textBox.getText())) { // "0000-00" is the special "Erase Me" code for these text boxes. ignore = true; textBox.setText(" - "); ignore = false; } // Changing focus to a different textBox by using "setFocus()" method. differentTextBox.setFocus(); } } } ); As you can see, the only method I've figured out to clear this text widget from a different point in the code is by assigning "0000-00" textBox.setText("000000") and checking for that input in the listener. When that input is received, the listener changes the text back to " - " (four spaces, a hyphen, then two spaces). There is also a focusLost Listener that parses this text widget for spaces, then in order to avoid unnecessary SQL queries, it clears/resets all fields if the input is invalid (i.e contains spaces). // Adding focus listener to textBox to wait for loss of focus to perform SQL statement. textBox.addFocusListener(new FocusAdapter() { @Override public void focusLost(FocusEvent evt) { // Get the contents of otherTextBox and textBox. (otherTextBox must be <= textBox) String boxFour = otherTextBox.getText(); String boxFive = textBox.getText(); // If either text box has spaces in it, don't perform the search. if (boxFour.contains(" ") || boxFive.contains(" ")) { // Don't perform SQL statements. Debug statement. System.out.println("Tray Position input contains spaces. Ignoring."); //Make all previous results invisible, if any. labels.setVisible(false); differentTextBox.setText(""); labelResults.setVisible(false); } else { //... Perform SQL statement ... } } } ); OK. Often, I use SWT MessageBox widgets in this code to communicate to the user, or wish to change the text widgets back to an empty state after verifying the input. The problem is that messageboxes seem to create a focusLost event, and using the .setText(string) method is subject to SWT.Verify listeners that are present on the text widget. Any suggestions as to selectively ignoring these listeners in code, but keeping them present for all other user input? Thank you in advance for your assistance.

• C#/.NET: TextBox is not 'focused' after a process was initiated

  - by eibhrum

  Hi, I am having a problem after opening the notepad once I click the button "btnSearch". The idea is that once I clicked the button 'btnSearch', the textbox 'txtSearch' should be 'focused' even after a process was initiated/opened outside the main window. Here's my code: private void btnSearch_Click(object sender, RoutedEventArgs e) { System.Diagnostics.Process.Start("notepad"); txtSearch.Focus(); // not working } Any suggestions?

• Do I lose anything by coding in c# and using free online vb.net code convertors?

  - by Gullu

  The company I work for uses vb.net since there are many programmers who moved up from vb6 to vb.net. Basically more vb.net resources in the company for support/maintenance vs c#. I am a c# coder and was wondering if I could just continue coding in c# and just use the many online free c# to vb.net code convertors. That way, I will be more productive and also be more marketable since there are more c# jobs compared to vb.net jobs. I have done vb6 many years ago and I am comfortable debugging vb.net code. It's just the primary coding language. I am more comfortable in c#. Will I lose anything if I use this approach. (code conversion). Based on what i read online the future of vb.net is really "Dim". Please advise. thank you

• Found a good tool for jQuery Coding &ndash; jQueryPad

  - by Shaun

  Just found a good (looks like) tool for jQuery coding and debugging from the appinn.com (Chinese) named jQueryPad by Paul Stovell. With it we don’t need to switch between the visual studio and the browser when coding and debugging. There’s only one main screen where we can type the HTML and jQuery code and just press F5 to see the result in the bottom frame. .NET Frameworks 3.5 is required.   Hope this helps.

• Good source for interview-style coding problems for entry/intermediate developers?

  - by soster

  I have taught myself to code over the past few years and do not have a computer science degree. As a result, I lack experience from many things, such as the basic homework/test questions many CS graduates take for granted. I recently had a tech screen interview where I fumbled and struggled to finish a (relatively) common question, I believe due to this inexperience. My question to all of you is this: do you know a good source for a bunch of these problems that includes answers, for an entry/intermediate developer who is trying to gain coding problem solving experience? The ones I've been able to find on the internet are for coding teams, so they're a bit too complicated for me. Thanks so much in advance.

• How do I recover my accidentally lost Windows partitions after installing Ubuntu?

  - by Totally newbie

  I have a Toshiba satellite A-200 laptop with a Vista OS on it with 4 NTFS partitions (C:) Vista (D:) Entertainment (E:) Work (F:) Sources and I wanted to start using Ubuntu instead. So I tried it first from the live CD and everything was OK and all the partitions were shown and working and so I decided to install Ubuntu to replace Vista on the (C:) drive. After I did that I can no longer find my folders and files on the (D:), (E:), (F:) partitions and the only file system that is shown is one 198 GB although my HDD is 320 GB. I can't access the lost data on the remaining 120 GB which I hope is still there and not totally lost I am now working from the live CD but I am unable to install testdisk. Can I recover the Vista partitions by the product recovery CD to get my laptop back to the factory settings? Can I recover the NTFS partitions using a recovery program for Windows or will that make the problem worse? I need these data badly as I don't have a backup for them.

• TeamSpeak 3 Disconnects

• What's so bad about in-line CSS?

  - by ChessWhiz

  When I see website starter code and examples, the CSS is always in a separate file, named something like "main.css", "default.css", or "Site.css". However, when I'm coding up a page, I'm often tempted to throw the CSS in-line with a DOM element, such as by setting "float: right" on an image. I get the feeling that this is "bad coding", since it's so rarely done in examples. I understand that if the style will be applied to multiple objects, it's wise to follow "Don't Repeat Yourself" (DRY) and assign it to a CSS class to be referenced by each element. However, if I won't be repeating the CSS on another element, why not in-line the CSS as I write the HTML? The question: Is using in-line CSS considered bad, even if it will only be used on that element? If so, why? Example (is this bad?): <img src="myimage.gif" style="float:right" />

• Checkstyle for C#?

  - by PSU_Kardi

  I'm looking to find something along the lines of Checkstyle for Visual Studio. I've recently started a new gig doing .NET work and realized that coding standards here are a bit lacking. While I'm still a young guy and far from the most experienced developer I'm trying to lead by example and get things going in the right direction. I loved the ability to use Checkstyle with Eclipse and examine code before reviews so I'd like to do the same thing with Visual Studio. Anyone have any good suggestions? Another thing I'd be somewhat interested in is a plug-in for SVN that disallows check-in until the main coding standards are met. I do not want people checking in busted code that's going to wind up in a code review. Any suggestions at this point would be great.

• Is there anyone out there that codes like I do?

  - by Jacob Relkin

  Hi, Some people have told me that my coding style is a lot different than theirs. I think I am somewhat neurotic when it comes to spacing and indenting though. Here's a snippet to show you what I mean: - ( void ) applicationDidFinishLaunching: ( UIApplication *) application { SomeObject *object = [ [ SomeObject alloc ] init ]; int x = 100 / 5; object.someInstanceVariable = ( ( 4 * x ) + rand() ); [ object someMethod ]; } Notice how I space out all of my brackets/parentheses, start curly braces on the same line, "my code has room to breathe", so to speak. So my questions are a) is this normal and b) What's your coding style?

• Do you put a super() call a the beginning of your constructors?

  - by sleske

  This is a question about coding style and recommended practices: As explained in the answers to the question unnecessary to put super() in constructor?, if you write a constructor for a class that is supposed to use the default (no-arg) constructor from the superclass, you may call super() at the beginning of your constructor: public MyClass(int parm){ super(); // leaving this out makes no difference // do stuff... } but you can also omit the call; the compiler will in both cases act as if the super() call were there. So then, do you put the call into your constructors or not? On the one hand, one might argue that including the super() makes things more explicit. OTOH, I always dislike writing redundant code, so personally I tend to leave it out; I do however regularly see it in code from others. What are your experiences? Did you have problems with one or the other approach? Do you have coding guidelines which prescribe one approach?

• Unexpected key-value behavior in a Core Data Context

  - by ????

  If I create an array of strings (via key-value coding) containing the names of a Managed Object entity's attributes which are stored in the App Delegate the first time, I get an array of NSStrings without any problems. If I subsequently make the same call later from the same entry point in code, that same collection becomes an array of NULL objects- even though nothing in the Core Data Context has changed. One unappealing work-around involves re-creating the string array every time, but I'm wondering if anyone has a guess as to what's happening behind the scenes. // Return an array of strings with the names of attributes the Activity entity - (NSArray *)activityAttributeNames { #pragma mark ALWAYS REFRESH THE ENTITY NAMES? //if (activityAttributeNames == nil) { // Create an entity pointer for Activity NSEntityDescription *entity = [NSEntityDescription entityForName:@"Activity" inManagedObjectContext:managedObjectContext]; NSArray *entityAttributeArray = [[NSArray alloc] initWithArray:[[entity attributesByName] allValues]]; // Extract the names of the attributes with Key-Value Coding activityAttributeNames = [entityAttributeArray valueForKeyPath:@"name"]; [entityAttributeArray release]; //} return activityAttributeNames; }

• The 80 column limit, still useful?

  - by Tim Post

  Related: While coding, how many columns do you format for? Is there a valid reason for enforcing a maximum width of 80 characters in a code file, this day and age? I mostly use C, however this question is language agnostic. Its also subjective, so I'll tag it as such. Many individual projects set their own various coding standards, a guide to adjust your coding style. Many enforce an 80 column limit on code, i.e. don't force a dumb 80 x 25 terminal to wrap your lines in someone else's editor of choice if they are stuck with such a display, don't force them to turn off wrapping. Both private and open source projects usually have some style guidelines. My question is, in this day and age, is that requirement more of a pest than a helper? Does anyone still login via the local console with no framebuffer and actually edit code? If so, how often and why cant you use SSH? I help to manage a few open source projects, I was considering extending this limit to 110 columns, but I wanted to get feedback first. So, any feedback is appreciated. I can see the need to make certain OUTPUT of programs (i.e. a --help /h display) 80 columns or less, but I really don't see the need to force people to break up code under 110 columns long into 2 lines, when its easier to read on one line. I can also see the case for adhering to an 80 column limit if you're writing code that will be used on micro controllers that have to be serviced in the field with a god-knows-what terminal emulator. Beyond that, what are your thoughts? Edit: This is not an exact duplicate. I am asking very specific questions, such as how many people are actually still using such a display. I am also not asking "what is a good column limit", I'm proposing one and hoping to gather feedback. Beyond that, I'm also citing cases where the 80 column limit is still a good idea. I don't want a guide to my own "c-style", I'm hoping to adjust standards for several projects. If the duplicate in question had answered all of my questions, I would not have posted this one :) That will teach me to mention it next time. Edit 2 question |= COMMUNITY_WIKI
