• Any reason to clean up unused imports in Java, other than reducing clutter?

  - by Kip

  Is there any good reason to avoid unused import statements in Java? As I understand it, they are there for the compiler, so lots of unused imports won't have any impacts on the compiled code. Is it just to reduce clutter and to avoid naming conflicts down the line? (I ask because Eclipse gives a warning about unused imports, which is kind of annoying when I'm developing code because I don't want to remove the imports until I'm pretty sure I'm done designing the class.)

• Why does this crash: stringByAppendingFormat

  - by Emil

  Hey. My code crashes at this function (at the stringByAppendingFormat: with error objc_msgSend() selector name: stringByAppendingFormat). This is that line: // imagesPath = ...iPhone Simulator/4.0/Applications/NUMBERS/Documents/images UIImage *image = [[UIImage alloc] initWithContentsOfFile:[imagesPath stringByAppendingFormat:@"/%d.png", [[self.postsArrayID objectAtIndex:row] intValue]]]; Could it have something to do with the retaining of objects? Thanks :)

• How to change the default "double click" action of a web service in a class library (VS2010)?

  - by JL

  I have a web service defined as follows, residing in a class library: [WebService(Namespace = "http://comp.com/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. // [System.Web.Script.Services.ScriptService] public class SendingItems_new : System.Web.Services.WebService When I double click it, instead of going to code view, it shows the design view. I NEVER use design view, so how can I get it to open up code view instead, its very annoying having to flick from design view each time. Thank you
