  - by Mordan

  What's the fastest way to draw a Hello World on the screen as a GUI in Java, 1- by using the minimum number of classes. 2- with the least byte code executed 2- the JVM tweaks so when I double click on the Jar file in Windows, the Hello World appears in no time (assuming the Runtime is not already loaded).

• Hello World to Twitter from C#

  - by cf_PhillipSenn

  A few days ago, I posted this question and this question asking about how to post "Hello World" to twitter. I've gotten helpful responses, which have propelled me further along, but I'm still lost. I need to use OAuth because (as I read it) using username and password is going to be deprecated soon. I need an example as simple as updating the status with the string constant 'Hello World!'. My client is specifying that I must use C#.

• Hello world/Console Project in Visual Studio 2008 64 bit

  - by grobartn

  So I am trying to run console 64 bit Hello World program. I have Windows 7 Enterprise x64 bit version. I have installed Visual Studio 2008 and have added all of components needed for 64 bit. I want to create simple console application. It turns out to be a problem. I have simple standard hello world project. I have created it using New Project - Empty project. I added main.cpp that contains this: #include <iostream> using namespace std; int main() { cout << "howdy\n"; } I added new configuration to the project by clicking on Config Manager and added x64 config. Compiled and it compiles. Tried running it and cmd.exe shoots up with following error: "The application has failed to start because its side-by-side configuration is in correct. Please see the application event log or use the command-line sxstrace.e xe tool for more detail. Press any key to continue . . . " Which set-up step if any I am missing. What am I doing wrong and how should I go about setting simple console hello world in 64 bit world. Thanks for any help

• More issues with IntelliJ 9.0.1 "Hello World" in Scala - Predef version 5.0 vs 4.1

  - by Alex R

  Any ideas what could cause this? Scala signature Predef has wrong version Expected 5.0 found: 4.1 in .... scala-library.jar I tried both versions 2.7.6 and 2.8 RC1 of scala-*.jar, the result was the same. JDK is 1.6.u20. UPDATE Today uninstalled IntelliJ 9.0.1, and installed 9.0.2 Early Availability, with the 4/14 stable version of the Scala plug-in. Then I setup a project from scratch through the wizards: new project from scratch JDK is 1.6.u20 accept the default (project) instead of global / module accept the download of Scala 2.8.0beta1 into project's lib folder Created a new class: object hello { def main(args: Array[String]) { println("hello: " + args); } } For my efforts, I now have a brand-new error :) Here it is: Scalac internal error: class java.lang.ClassNotFoundException [java.net.URLClassLoader$1.run(URLClassLoader.java:202), java.security.AccessController.doPrivileged(Native Method), java.net.URLClassLoader.findClass(URLClassLoader.java:190), java.lang.ClassLoader.loadClass(ClassLoader.java:307), sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301), java.lang.ClassLoader.loadClass(ClassLoader.java:248), java.lang.Class.forName0(Native Method), java.lang.Class.forName(Class.java:169), org.jetbrains.plugins.scala.compiler.rt.ScalacRunner.main(ScalacRunner.java:72)] Thanks

  - by George

  Besides adding these File Types to IIS and installing the .NET framework 4.0 to the Web Server, what else do I need to do to get a Hello Word Silver Light web app to work? is there a separate Silverlight installation needed? Though the web site works when I deploy locally, I am getting the following error after deploying to a remote web server: Line: 54 Error: Unhandled Error in Silverlight Application Code: 2104 Category: InitializeError Message: Could not download the Silverlight application.

• Post "Hello World" to twitter from .NET application

  - by cf_PhillipSenn

  My client would like me to use .NET to post to Twitter, and suggests that I use C#. Q: How do I post "Hello World" to twitter using C#? This post mentions a library called twitterizer. Isn't there a native way to do it without using a 3rd party library? (Maybe not since authentication is one of the requirements).

• MonoTouch Hello World for iPad

  - by Bryan

  I have tried following the sample Hello World for MonoTouch by creating an iPad solution. For some reason I cannot get the MainWindow to load. I followed the instructions exactly and the app just closes before even loading a view. Is there something missing? Do I need to tell the solution how to load the MainWindow.XIB or something? Please help, this seems very basic and I am about to throw MonoTouch in the garbage.

• it takes 2 seconds to compile a hello world C++ project in netbeans (windows)

  - by Ethan

  I used code:blocks as the C++ IDE on Windows. I switched to netbeans 6.8 (with C/C++ plugin, MinGW, MSYS) recently, because netbeas have the nice feature of "checking syntax errors when typing" (same as working on Java or PHP projects). But the painful thing is that, it takes 2 seconds to compile a simple hello world project in netbeans. Any trick to make it as fast as code:blocks, or at least make the compiling time no more than 0.5 second?

• Android "hello world" - versions

  - by Ianb

  Starter question: My "Hello World" attempt won't run, ("No compatible targets were found"), I think this is bacause I selected the latest version for my project (2.2), and the highest AVD version is 2.0.1. Does this make sense? Can I change my project version (haven't been able to find a way to do this), or do I have to start again? If the versions are not backwards compatible, what is the best version to use for the majority of Android devices out there? Thanks

• Error when connecting to hello world yesod example on Windows 8

  - by reltone

  I start the executable (after building it with cabal) and it says "Application launched, listening on port 3000." Next I connect to it with my web browser and the console says "threadWaitRead requires -threaded on Windows, or use System.IO.hWaitForInput." The web browser never connects. Not sure what this is actually recommending I do to resolve the problem. {-# LANGUAGE TypeFamilies, QuasiQuotes, MultiParamTypeClasses, TemplateHaskell, OverloadedStrings #-} import Yesod data HelloWorld = HelloWorld mkYesod "HelloWorld" [parseRoutes| / HomeR GET |] instance Yesod HelloWorld getHomeR :: Handler RepHtml getHomeR = defaultLayout [whamlet|Hello World!|] main :: IO () main = warpDebug 3000 HelloWorld

• Android "Hello, MapView" Tutorial - Map Tiles Do Not Load

  - by Onyx

  I am new to Android software development and new to this site. I am hoping someone might have some experience with the problem I am having. I've been following the Hello, MapView tutorial in order to not only learn the Android framework, but also the Google Maps library. I've tried my best to implement things exactly as the tutorial has instructed. My problem is that the application does load in my emulator (or even on my phone for that matter), but the map tiles do not load. Searching Google I found a post by someone else on another site having the same issue, but his/her problem was that the important elements added to the AndroidManifest.xml file were not in the right order. I double-checked this in mine, but everything seems to be right. So, I am not sure what the issue is and was hoping others have seen this before. I can provide any snippets of code, if that would help. Thank you.

• Eclipse IDE's Hello World Cheatsheet seems to have a mistake

  - by Sean

  Hey guys, Just a warning: I'm completely new to Java and am trying to teach myself Android programming. I installed the Eclipse IDE today and tried to walk through the first Java Hello World "cheat sheet," and it didn't work! I was really quite surprised. When it asked me to select the checkbox to create the main() method, there wasn't anything on-screen that looked like a checkbox with "main()" or "method" next to it, so I guessed that maybe what they meant was the "Modifiers" radio button. So I left that checked for "public." It didn't compile and I got red X's next to every folder in my Package Explorer. Has anybody else had this problem? Thanks!

• Stuck at "Hello World" with IntelliJ IDEA 9.0.1 for Scala

  - by Alex R

  I've been using Eclipse since 2.x and and IDEs in general for over 20 years (since Turbo Pascal and Turbo C in the late '80s!). (that preamble is supposed to imply, "I'm not an idiot" ... LOL :-] ) I'm trying to use the debugger in IntelliJ 9.0.1. I've resigned myself to an old standby: class hello { def main(a: Array[String]) = println("got args: " + a) } Alas, I'm unable to get even this simple Scala example to run. I'd like to eventually put a breakpoint in it, but for now just running it would be great. I have Java 1.6u20 and the Scala plug-in 0.3.473 (January 2010). The error below summarizes my experience: What possibly could I be doing wrong? Thanks

• PHP - HTML Purifier - hello w<o>rld/world tutorial striptags

  - by JW

  I am just looking into using HTML Purifier to ensure that a user-inputed string (that represents the name of a person) is sanitized. I do not want to allow any html tags, script, markup etc - I just want the alpha, numeric and normal punctuation characters. The sheer number of options available for HTML Purifier is daunting and, as far as i can see, the docs do not seem to have a beggining/middle or end see: http://htmlpurifier.org/docs Is there a simple hello world tutorial online that shows how to sanitize a string removing all the bad stuff out of it. I am also considering just using strip tags: http://php.net/manual/en/function.strip-tags.php or PHP's in built data sanitizing http://us.php.net/manual/en/book.filter.php

• Android : Hello, Views > Google Map View Tuorial

  - by Tom

  Hi, I'm trying to complete the Android MapView tutorial @ www.developer.android.com/resources/tutorials/views/hello-mapview.html I think I've done the entire thing correctly but I'm getting an error message in Eclipse. I'm sure why. The problematic line of code is private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>(); I'm relatively new to Java but I've gone through the forums of different things and I really have no idea on this one. I've [attached][2] a screen shot of the development environment - hopefully it wont be anything too obvious or hard to fix either! http://lh5.ggpht.com/_sqCs2rXr5hQ/S-CJf4x9ZUI/AAAAAAAAAHI/IR-kTcOnfU8/s144/hellogooglemaps.jpg Cheers Tom :)
