  • Making a vertically scrolling parent div which does not cause overflow of children

    - by marq
    I have something as follows: <div style="float: left; height: 20px; overflow-y: scroll"> <div>hello this is a test</div> <div>hello this is another test</div> <div>t1</div> <div>t2</div> <div>t3</div> </div> The parent div grows to the appropriate width to fit the largest child (which is what I want). However, the vertical scrollbar causes the inner width to be smaller, which causes the largest child to wrap. Is there a way to get the parent to grow to the width of the largest child + the width of the scroll bar? I've tried every margin trick I know, but nothing.

  • Spring 3 Annotations

    - by jboyd
    I can't get spring annotations to work at all, I'm just trying to get the simplest thing to work... .../mycontext/something - invokes method: @RequestMapping(value = "/something") @ResponseBody public String helloWorld() { System.out.println("hello world"); return "Hello World"; } My main problem is no matter how hard I try, I can't find a complete SIMPLE example of the configuration files needed, every spring tutorial is filled with junk, I just one one controller to handle a request with a mapping and can't get it to work does anyone know of a simple and complete spring example. pet-clinic is no good, it's way too complicated, I have a tiny basic use case and it's proving to be a real pain to get working (this always happens with Spring)

  • When does printf("%s", char*) stop printing?

    - by remagen
    In my class we are writing our own copy of C's malloc() function. To test my code (which can currently allocate space fine) I was using: char* ptr = my_malloc(6*sizeof(char)); memcpy(ptr, "Hello\n", 6*sizeof(char)); printf("%s", ptr); The output would typically be this: Hello Unprintable character Some debugging figured that my code wasn't causing this per say, as ptr's memory is as follows: [24 bytes of meta info][Number of requested bytes][Padding] So I figured that printf was reaching into the padding, which is just garbage. So I ran a test of: printf("%s", "test\nd"); and got: test d Which makes me wonder, when DOES printf("%s", char*) stop printing chars?

  • Are large include files like iostream efficient? (C++)

    - by Keand64
    Iostream, when all of the files it includes, the files that those include, and so on and so forth, adds up to about 3000 lines. Consider the hello world program, which needs no more functionality than to print something to the screen: #include <iostream> //+3000 lines right there. int main() { std::cout << "Hello, World!"; return 0; } this should be a very simple piece of code, but iostream adds 3000+ lines to a marginal piece of code. So, are these 3000+ lines of code really needed to simply display a single line to the screen, and if not, do they create a less efficient program than if I simply copied the relevant lines into the code?

  • Casting to generic type in Java doesn't raise ClassCastException?

    - by Kip
    I have come across a strange behavior of Java that seems like a bug. Is it? Casting an Object to a generic type (say, K) does not throw a ClassCastException even if the object is not an instance of K. Here is an example: import java.util.*; public final class Test { private static<K,V> void addToMap(Map<K,V> map, Object ... vals) { for(int i = 0; i < vals.length; i += 2) map.put((K)vals[i], (V)vals[i+1]); //Never throws ClassCastException! } public static void main(String[] args) { Map<String,Integer> m = new HashMap<String,Integer>(); addToMap(m, "hello", "world"); //No exception System.out.println(m.get("hello")); //Prints "world", which is NOT an Integer!! } }

  • Namespace Autoload works under windows, but not on Linux

    - by EvilChookie
    I have the following php code: index.php <?php spl_autoload_extensions(".php"); spl_autoload_register(); use modules\standard as std; $handler = new std\handler(); $handler->delegate(); ?> modules\standard\handler.php <?php namespace modules\standard { class handler { function delegate(){ echo 'Hello from delegation!'; } } } ?> Under Windows 7, running WAMP, the code produces the message "Hello from Delegation!" however under Linux, I get the following: Fatal error: spl_autoload(): Class modules\standard\handler could not be loaded in /var/www/index.php on line 15 Windows is running PHP 5.3.0 under WAMP, and Linux is running the 5.3.2 dotdeb package under Ubuntu 9.10. Is this a configuration issue on my linux box, or just a difference in the way namespaces and autoloading is handled on the different operating systems

  • How to add custom hooks to controllers in ASP.NET MVC2

    - by Adrian
    Hi, I've just started a new project in ASP.net 4.0 with MVC 2. What I need to be able to do is have a custom hook at the start and end of each action of the controller. e.g. public void Index() { *** call to the start custom hook to externalfile.cs (is empty so does nothing) ViewData["welcomeMessage"] = "Hello World"; *** call to the end custom hook to externalfile.cs (changes "Hello World!" to "Hi World") return View(); } The View then see welcomeMessage as "Hi World" after being changed in the custom hook. The custom hook would need to be in an external file and not change the "core" compiled code. This causes a problem as with my limited knowledge ASP.net MVC has to be compiled. Does anyone have any advice on how this can be achieved? Thanks

  • Import Namespace System.Query

    - by GateKiller
    I am trying to load Linq on my .Net 3.5 enabled web server by adding the following to my .aspx page: <%@ Import Namespace="System.Query" %> However, this fails and tells me it cannot find the namespace. The type or namespace name 'Query' does not exist in the namespace 'System' I have also tried with no luck: System.Data.Linq System.Linq System.Xml.Linq I believe that .Net 3.5 is working because var hello = "Hello World" seems to work. Can anyone help please? Cheers, Stephen PS: I just want to clarify that I don't use Visual Studio, I simple have a Text Editor and write my code directly into .aspx files.
