• How to stop C# compile on first error in VS 2010 (VS 2008 macros don't work)!

  - by Ben Robbins

  At work we have a C# solution with over 80 projects. Is it possible in VS 2010 to automatically stop compilation as soon as an error is encountered rather than the default behaviour which is to continue as far as possible and display a list of errors in the error window? I'm happy for it to stop either as soon as an error is encountered (file-level) or as soon as a project fails to build (project-level). I'd also note that in VS 2008 we used macros similar to some of the answers below but they don't work in VS 2010 (at least I couldn't get them to as the environment events don't seem to fire in VS 2010).

• Increasing nesting in sub headings with LaTeX

  - by Andreas Grech

  The following is an example of what I currently have: \setcounter{secnumdepth}{3} \chapter{The Chapter} \section{First Section} \subsection{First sub Section} \subsubsection{First sub sub Section} which renders something like this: Chapter 1 The Chapter 1.1 First Section 1.1.1 First Sub Section 1.1.1.1 First sub sub Section Now unfortunately in LaTeX, I can only go down to a subsubsection (1.1.1.1) but I need to be able to go down further...for example, something like this 1.1.2.1.3. Are there any commands that will allow me to do this?

• What does the C standard say about pointers to structs and their first member?

  - by James Morris

  Consider the following two struct: struct a { int a; }; struct b { struct a a_struct; int b; }; the following instantiation of struct b: struct b b_struct; and this condition: if (&b_struct == (struct b*)&b_struct.a_struct) printf("Yes\n"); Does the C standard mandate this to always evaluate true?

• How to check for and remove a newline (\n) in the first line of a text field in actionscript?

  - by Steven

  In the script, sometimes a newline is added in the beginning of the text field (am using a textArea in adobe flex 3), and later on that newline might need to be removed (after other text has been added). I was wondering how to check if there is a newline at the beginning of the text field and then how to remove it. Thanks in advance.

• How can I download YouTube videos using .NET code?

  - by JMSoft

  Does anybody know the VB or C# code to programmatically download a video from YouTube? I have gone through all related questions on this site and the only code I have found (which uses the WebClient Class webclient.DownloadFileAsync) returns the text source of the video, but not the Flash video (.flv) file that needs to be downloaded? Do you know any SDK or library which can help? I have also downloaded the GoogleAPI (YouTube DLL) but have not found a way of doing it.

• I would like to learn C++, what is the first step ?

  - by Cesar

  My actual experience comes from PHP and Delphi(Borland) and recently also from Obj-C (iPhone sdk). In the past I also used Java, Python, VB 6 and some other scripting language. I would like to learn C++ because i need a standard tool for write compiled applications with good performance but i have no idea about witch environment i have to choose (Ex: Borland, Microsoft, Eclipse+MinGW, ...). Based those parameters: Most useful more opensource project or work requests Most standard not a proprietary versions Biggest community documentation, manuals, tutorials, forums... Better IDE add-ons, highlight, debug, cross platform, autocomplete... Easy setup A simple setup, to focus on learning the basics Actually I'm on OSX but I can use a VM if needed. Advices about tutorial or books are welcome. I hope it's not too generic as question.

• sharpziplib - can you add a file without it copying the entire zip first?

  - by schmoopy

  Im trying to add an existing file to a .zip file using sharpziplib - problem is, the zip file is 1GB in size. When i try to add 1 small file (400k) sharpziplib creates a copy/temp of the orig zip file before adding the new file - this poses a problem when the amount of free disk space is less than 2x the zip file you are trying to update. for example: 1GB zip myfile.zip 1GB zip myfile.zip.tmp.293 ZipFile zf = new ZipFile(path); zf.BeginUpdate(); zf.Add(file); // Adding a 400k file here causes a 1GB temp file to be created zf.EndUpdate(); zf.Close(); Is there a more efficient way to do this? Thanks :-)

• How can I read barcodes without having the user focus a text box first?

  - by Atlas

  I recently acquired a Metrologic Barcode scanner (USB port), as everyone already knows it works as a keyboard emulator out of the box. How do I configure the scanner and my application so that my app can process the barcode data directly? That is, I don't want the user to focus on a "Text field" and then process the data when the KeyPress event fires.

• does code in finally get run after a return in objective-c?

  - by Kevlar

  consider the following code: @try { if (something.notvalid) { return; } // do something else } @catch (NSException *ex) { // handle exception } @finally { NSLog(@"finally!"); } if something is not valid and i return from within the try, does the code in @finally execute or not? I believe that it should but others I've spoken to don't think so and i'm unable to test this at the moment.

• How to perform a Depth First Search iteratively using async/parallel processing?

  - by Prabhu

  Here is a method that does a DFS search and returns a list of all items given a top level item id. How could I modify this to take advantage of parallel processing? Currently, the call to get the sub items is made one by one for each item in the stack. It would be nice if I could get the sub items for multiple items in the stack at the same time, and populate my return list faster. How could I do this (either using async/await or TPL, or anything else) in a thread safe manner? private async Task<IList<Item>> GetItemsAsync(string topItemId) { var items = new List<Item>(); var topItem = await GetItemAsync(topItemId); Stack<Item> stack = new Stack<Item>(); stack.Push(topItem); while (stack.Count > 0) { var item = stack.Pop(); items.Add(item); var subItems = await GetSubItemsAsync(item.SubId); foreach (var subItem in subItems) { stack.Push(subItem); } } return items; } EDIT: I was thinking of something along these lines, but it's not coming together: var tasks = stack.Select(async item => { items.Add(item); var subItems = await GetSubItemsAsync(item.SubId); foreach (var subItem in subItems) { stack.Push(subItem); } }).ToList(); if (tasks.Any()) await Task.WhenAll(tasks); UPDATE: If I wanted to chunk the tasks, would something like this work? foreach (var batch in items.BatchesOf(100)) { var tasks = batch.Select(async item => { await DoSomething(item); }).ToList(); if (tasks.Any()) { await Task.WhenAll(tasks); } } The language I'm using is C#.

• Is a C++ compiler allowed to emit different machine code compiling the same program?

  - by sharptooth

  Consider a situation. We have some specific C++ compiler, a specific set of compiler settings and a specific C++ program. We compile that specific programs with that compiler and those settings two times, doing a "clean compile" each time. Should the machine code emitted be the same (I don't mean timestamps and other bells and whistles, I mean only real code that will be executed) or is it allowed to vary from one compilation to another?

• How can you get the first digit in an int (C#)?

  - by Dinah

  In C#, what's the best way to get the 1st digit in an int? The method I came up with is to turn the int into a string, find the 1st char of the string, then turn it back to an int. int start = Convert.ToInt32(curr.ToString().Substring(0, 1)); While this does the job, it feels like there is probably a good, simple, math-based solution to such a problem. String manipulation feels clunky. Edit: irrespective of speed differences, mystring[0] instead of Substring() is still just string manipulation

• What is faster: write PHP code using "functions" or writing it as pure script?

  - by Ole Jak

  What is faster: writing PHP code using functions or writing it as pure script? So, as I see it Apache or any other server will create from PHP code using functions a pure script... I mean we had: function foo($a, $b){ return ($a + $b); echo foo(4, 5)} and Apache will turn it into something like: echo (5 + 4) Or will it?
