• Secrets of delivering .NET size large products?

  - by Joan Venge

  In software companies I have seen it's really hard to work on very large products where everything depends on everything else. For instance Microsoft works on C#, F#, .NET, WPF, Visual Studio where these things are interconnected. I don't know how many people are involved, but if it's in 100s, how do they keep in sync with everything, so they design and implement features without conflicting with other dependencies and future plans of other products? I am wondering that if MS is able to do this, they must have a very good system. Any guidelines or secrets for MS or non-MS very large software product delivering?

• Drawing a waveform in C#

  - by user488792

  Hi! I want to be able to display a WaveForm in C#, along with some simple features such as zooming and selection. I already have the data as a short[] of amplitude values. However, I am an amateur when it comes to hardcoding GUI. I have already found a possible helper class WaveFormClass that may help me achieve this but as a backup, I want to learn how to manually do it. So may I ask for some methods and possibly some links that will help? Thanks!

• Best practices to keep up a diverging branch of code

  - by JS_is_bad

  I'm in a situation where some minor patches I've submitted to an open-source project were ignored or explicitly not accepted. I consider them useful, but more important is that I need the functionality they implement. I don't want to push my ideas and suggestions anymore to the main contributors, because I don't want to turn this into an ego issue. I've decided that my best bet would be just to use what I wrote for my own purposes. I don't want to fork the whole source code tree because I like how things are generally working, I'm just not happy with details. But I do realize that the project will evolve and I would like to use the new features that will eventually appear. I understand that I'll have to merge all new things into my own source tree. Are there any best practices for this scenario?

• calling javascript function inside orkut iframe

  - by tsetsik

  Hi guys, I'm having a web game loaded in orkut application via iframe so there are the orkut iframe and mine iframe inside the xml. Everything is ok, but now I need to have a button for inviting some friends and wall posts from some features. I didn't find a way for including the orkut javascript in the game's code so the first thing that pops into my mind was to call a custom function in the xml by using: window.parent.myFunction(); but it gives me error: permission denied. I've tried some other ways of reaching that function but the error is the same. Does anybody know a way of doing that or this can't be done ?

• Java - Post to Twitter

  - by Ibolit

  Hi. I've written a simple web application, which i want to post tweets. I have seen some java libraries for working with twitter, and they all seem like too much of work for something that seemingly simple. But it is possible that i am missing something. And I am yet to make any of them work... Is there any simple way to post a tweet in twitter from a web-app in java with only a few lines of code? Thank you very much.

• How do I Capture native (Menu) button presses in PhoneGap?

  - by Dinedal

  By calling "BackButton.override();" and then hooking on to the backKeyDown event, I am able to get the back button press to register. But there doesn't appear to be a "MenuButton.override();" Also, hooking on the menuKeyDown doesn't register a button press. Here's my (non-functional) code. What am I missing? <script type="text/javascript" charset="utf-8" src="phonegap.js"></script> <script type="text/javascript" charset="utf-8"> document.addEventListener("deviceready", function() { alert('initialized'); }, false); document.addEventListener("menuKeyDown", function() { alert('menu_pressed'); // Never happens }, false); </script>

• Which PHP IDE would you use on Windows, if you're used to TextMate on the Mac?

  - by Dycey

  Until now, most of my PHP development had been done on a Mac in TextMate. For a new client I need to work on a secured windows box, and I was wondering which IDEs I should be looking at, as someone used to working with TextMate. I've tried the 'E' editor, and I'm unconvinced. I've tried IDEs on the Mac, and they always seem like poor relations... but given that I'm having to move development platforms anyway, is there something better I should be looking at? Are there any decent text editors out there that I'm missing?

• ValidateRect vs BeginPaint

  - by Armentage

  From the MSDN documentation: The BeginPaint function validates the entire client area. The ValidateRect function should not be called if a portion of the update region must be validated before the next WM_PAINT message is generated.1 I've been programming with Win32 API for years, and I've never thought to call the ValidateRect function. A co-worker of mine today pointed that we were missing a call to ValidateRect, which fixed a bug we were having doing some high-speed animation using GDI (I know, an oxymoron) Can someone tell me whether or not a call to ValidateRect is neccessary after a BeginPaint/EndPaint pair? I have seen no documentation at MSDN that sheds light on this, and what documentation and examples I do see that you do not need to.

• CodeIgniter won't run in a subdirectory

  - by Tim Piele

  I have a CodeIgniter install running in our root web directory that I copied into a subdirectory called /dev... I edited the config/config.php file to reflect the change so it is now like this: $config['base_url'] = 'http://mysite.com/dev'; $config['sbase_url'] = 'https://mysite.com/dev'; $config['default_email'] = '[email protected]'; $config['site_url'] = 'http://mysite.com/dev'; This is my .htaccess file: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1 [L] </IfModule> When I hover over any links on the site they are correct, for example the contact us page link reads www.mysite.com/dev/contact but when I click any of the links I get a 404 error... Is there something common I am missing?

• Setting a property from one collection to another collection

  - by ooo

  I have two colluections List<Application> myApps; List<Application> yourApps; These lists have overlapping overlapping data but they are coming from different sources and each source has some missing field data. Application object has a property called Description Both collections have a unique field called Key i want to see if there is a LINQ solution to: Loop through all applications in myApps and look at the key and see if that existing in yourApps. If it does, i want to take the description property from that application in yourApps and set the description property on the application on myApps to that same value i wanted to see if there was any slick way using lambda expressions (instead of having to have loops and a number of if statements.)

• What are the advantages of squashing assignment and error checking in one line?

  - by avakar

  This question is inspired by this question, which features the following code snippet. int s; if((s = foo()) == ERROR) print_error(); I find this style hard to read and prone to error (as the original question demonstrates -- it was prompted by missing parentheses around the assignment). I would instead write the following, which is actually shorter in terms of characters. int s = foo(); if(s == ERROR) print_error(); This is not the first time I've seen this idiom though, and I'm guessing there are reasons (perhaps historical) for it being so often used. What are those reasons?

• JavaScript prototype(ing) question

  - by OneNerd

  Trying to grasp Prototyping in Javascript. Trying to create my own namespace to extend the String object in JavaScript. Here is what I have so far (a snippet): var ns { alert: function() { alert (this); } } String.prototype.$ns = ns; As you can see, I am trying to place what will be a series of functions into the ns namespace. So I can execute a command like this: "hello world".$ns.alert(); But the problem is, the this doesn't seem to reference the text being sent (in this case, "hello world"). What I get is an alert box with the following: [object Object] Not having a full grasp of the object-oriented nature of JavaScript, I am at a loss, but I am guessing I am missing something simple. Does anyone know how to achieve this? Thanks -

• Why does this MSDN example for Func<> delegate have a superfluous Select() call?

  - by Dan

  The MSDN gives this code example in the article on the Func Generic Delegate: Func<String, int, bool> predicate = ( str, index) => str.Length == index; String[] words = { "orange", "apple", "Article", "elephant", "star", "and" }; IEnumerable<String> aWords = words.Where(predicate).Select(str => str); foreach (String word in aWords) Console.WriteLine(word); I understand what all this is doing. What I don't understand is the Select(str => str) bit. Surely that's not needed? If you leave it out and just have IEnumerable<String> aWords = words.Where(predicate); then you still get an IEnumerable back that contains the same results, and the code prints the same thing. Am I missing something, or is the example misleading?

• form data posted using linq-to-sql not showing until I refresh the page

  - by PeteShack

  I have an asp.net mvc app with a form. When you submit the form, it adds records to the sql database with linq-to-sql. After adding the records, the controller displays the form again, and should show those new values on the form. But, when it displays the form, the values are blank, until you refresh the page. While tracing through the code, I can see the records being added to the database when they are submitted, but the view doesnt display them, unless I refresh. The view is not the problem, it just displays the view model, which is missing the new records immediately after the post. I know this is kind of vague, but wasnt sure what parts of code to include here. Could this have something to do with data context life cycle? Basically, there is a data context created when the form is posted, then a different data context is created in the method that displays the form. Any suggestions on what might be causing this?

• Why use a "do while" loop?

  - by Stanni

  Hi, I've never understood why using a do while loops is necessary. I understand what they do, Which is to execute the code that the while loop contains without checking if the condition is true first. But isn't the below code: do{ document.write("ok"); } while(x == "10"){ document.write("ok"); } The exact same as: document.write("ok"); while(x == "10"){ document.write("ok"); } Maybe I'm being very stupid and missing something obvious out but I don't see the benefit of using do while over my above example.

• Receiving integers, but also want to test for char.

  - by Wayne Haworth

  Say I am looking to receive a series of numeric values and read them into an int, but I also want to test if the user hit key 'x'. I am sure I am missing something obvious, and have tried a few things but seem to be stuck. This is what I have so far... cout << endl << "Enter key (or 'x' to exit): "; cin key; if (key == 'x') { cout << "exiting";} // continue on...

• Deleted nib still displayed when controller is pushed

  - by yahuie

  I have an application with a UINavcontroller under a tab bar controller. To create the navigation model I want, I push a container UIView object onto the stack to manage additional views(Thanks Frank). When I created the container class, an associated nib file was created along with it. I at first used that nib file, but it turned out it was better not to. So I deleted the nib (and selected 'also move to trash'). The problem is that it still shows up when I push its view controller onto the stack. I have tried emptying the cache in xcode and restarting xcode. What am I missing?

• Entity Framework 5 not updating navigation properties in both entities

  - by Taylor

  I have updated a project to use the new Entity framework shipped with VS2012, however I have run into some of my code throwing exceptions. In the VS10 version of EF I was able to create or modify and Entity and use its navigation properties before calling SaveChanges() For example: A Navigation property of a client having a collection of Invoices. Client c = new Client(); Invoice I = new Invoice(); c.Invoices.Add(I); I would then be able to use Invoice.Client somewhere in my code before actually saving it without issue. Now Invoice.Client == null. Similarly in setting I.Client = C, I does not show up under C.Invoices What am I missing here or is this just simply how EF5 is?

• Prolem with if function

  - by Ryan

  Hi, something seems to be wrong with the first line of this if function, seems alright to me though. if ($count1 == sizeof($map) && $count2 == sizeof($map[0])){ echo ";"; }else{ echo ","; } This is the error I get (line 36 is the first line of the above line.) Parse error: parse error in C:\wamp\www\game\mapArrayConvertor.php on line 36 EDIT: The OP notes in an answer below that the error was a missing semi-colon on line 35 and not the code included in the question.

• Sorting a listview (Win32/C++)

  - by Zenox

  I'm trying to sort a listview when the user clicks on the column header. I am catching the LVN_COLUMNCLICK notification like so: case LVN_COLUMNCLICK: { NMLISTVIEW* pListView = (NMLISTVIEW*)lParam; BOOL test = ListView_SortItems ( m_hDuplicateObjectsList, ListViewCompareProc, pListView->iSubItem ); break; } However it seems to fail. My test variable is FALSE and my ListViewCompareProc never gets hit (it has a simple return 1 while I am trying to hit a debug point inside of it). Is there something I am missing for sorting a listview?
