• In few words, what can be said about Mocking process in TDD

  - by Richard77

  Hello, I'd like to brush my brain to avoid confusions. In few words, what can be said about Mocking process in TDD What's the GREAT idea behind MOCKING? Mocking frameworks are meant to be used only to avoid accessing DB during tests or they can be used for something else? For new comers (like me), are all the frameworks equal or I need to choose one for this or that reason? Thanks for helping

• Why is the software world full of status codes?

  - by David V McKay

  Why did programmers ever start using status codes? I mean, I guess I could imagine this might be useful back in the days when a text string was an expensive resource. WAYYY back then. But even after we had megabytes of memory to work with, we continued to use them. What possible advantage could there be for obfuscating the meaning of an error message or status message behind a status code?

• I write bad wave files using Java

  - by Cliff

  I'm writing out wave files in Java using AudioInputStream output = new AudioInputStream(new ByteArrayInputStream(rawPCMSamples), new AudioFormat(22000,16,1,true,false), rawPCMSamples.length) AudioSystem.write(output, AudioFileFormat.Type.WAVE, new FileOutputStream('somefile.wav')) And I get what appears to be corrupt wave files on OSX. They won't play from Finder however using the same code behind a servlet writing directly to the response stream and setting the Content-Type to audio/wave seems to play fine in quicktime. What gives?

• How to create an "endless" scrolling slideshow?

  - by Andrew

  I know a good bit of JS and I'm familiar with jQuery, and I'm trying to create an "endless" slideshow (like the one on http://thisismedium.com/), where the images scroll -- one right behind the other -- and when it reaches the end it loops. I don't really know how to start, so I was hoping someone could point me in the right direction. I created a slideshow before that automatically switched images and let you click Next and Previous, but I'm stuck here. =/.

• WPF Listbox display next element after SelectedItem

  - by Daniil Harik

  I have TextBox and ListBox with bunch of elements. TextBox has KeyDown event handler, the idea behind this is to allow user to press up and down keys to scroll inside ListBox while focus is on TextBox. When user presses "down key" several times, selected element becomes last visible element on screen. If user has reached bottom of visible list element on screen, I want him to see next element after selected element as well.

• Bring NSRunAlertPanel Dialogue to Front in Background Process

  - by mon4goos

  If you call NSRunAlertPanel() from a background process in Cocoa, the dialogue does not come to the front and instead stays behind other windows. This post shows that you can bring the dialogue to the front if you convert the process to a foreground process. If you keep the process a background process, however, is there any way to achieve this behavior?

• How to change the Page Title in ASP.Net 1.1 ?

  - by Andreas Grech

  With ASP.Net 2.0 you can use the Title property to change the page title : Page.Title = "New Title"; But since in ASP.Net 1.1 there isn't a Title property in the Page class, how can I change the page's title from the code-behind ?

• Gratuitous use of System.Runtime.Serialization attributes?

  - by rasx

  Is there any cost/drawback (apart from typing too much) to adorning a class with System.Runtime.Serialization attributes (like [DataContract]) such that it can be used locally as a direct reference to a desktop Client project or as a type for a WCF service? The goal here is to write a data-tier class that can be used in both rich client (WPF) and Web scenarios. My data classes will be in a project that is separate from Client and WCF (*.svc code-behind) code. Is this a valid attempt to reuse code?

• How to select an element by Class instead of ID in ASP.NET?

  - by firedrawndagger

  I have a few scatter elements which I am grouping together using a class like so - . In my code behind, using C# I want to hide these elements, using something like instructions.Visible = false;. However I realize I can only do this in codebehind if I use ID but this will result in invalid HTML/CSS Selector since you can't have multiple ID's with the same ID name... Alternatively is there another way to group the controls if not by class?

• Invalidating the HTTP Cache on read only front servers

  - by Microserf

  We have a CMS system and in the production mode a number of servers only have read-only access to the content (with a few exceptions) and the editors for the site work on the content on servers behind it (which are not available to the public). We're caching the content quite a long time on the front servers, but sometimes we want the content the editors publish to be available for visitors instantly. What would the best way be to invalidate the cache in this situation, should we trigger it from our code?

• Using of ApplicationSettings in markup code

• Seems like IE animates/processes my loading.gif even though I have set display:none?

  - by tobefound

  I believe this is happening because whenever I perform an ajax request (upon which the loading.gif is set to display:block) the animation does not start at the same position. The starting point feels random which led me to think the animation still goes on behind the scenes in IE. In Firefox the animation starts from "scratch" all the time. Any ideas?
