I am basically trying to return from a method which reads user input from the standard input stream. Since the user has the option to quit the application, I am trying to figure out the best way to do this exit. Ideally I will be able to return from begin() and let main() finish, thus quiting the applicaiton. public static void main(Str...
Hi, What is the common preference to name a method that has an out parameter inside? Usually I use Get as a prefix to mention that the method returns a value (like GetMyBusiness). But what if there is an out parameter that will be set after the method call? Should the method name mention this and focus only the return value? thanks...
Is there any difference between explicitly returning at the end of doGet or doPost-methods, and just letting the method return "by itself"? public void doGet(HttpSerlvetRequest req, HttpServletResponse resp) { <my code here> return; } public void doGet(HttpSerlvetRequest req, HttpServletResponse resp) { <my code here> } ...

I am trying to return (execute) a function from another file in an if statement. I have read that the return statement will not work, I was hoping someone would know what statement would allow me to call an outside function. The function creates a sandbox but if one exists I want to pass the if statement. This is a small snippet of cod...
I have to return a lot of values back to my windows application from my webService. But how would I return more than just a single string/int/boolean from my WebService to my Application. How would I return a collection, keyValuePair, or even better, a DataSet? Or is this just imposible? thank you :) ...
I'm trying to write a function that will return a reference to a PDO object. The reason for wanting a reference is if, for some reason, the PDO object gets called twice in one page load, it will just return the same object rather than initializing a new one. This isn't silly, is it? :/ function &getPDO() { var $pdo; if (!$pdo) ...
Hi, I have a question about the following code private void printTree(Node node){ if(node==null) return; printTree(node.left); System.out.print(node.data+" "); printTree(node.right); } I don't really get the point of 'return;' statement there. It looks like if node is null, code returns nothing. but then without that ...

Hi everyone, Some programs return immediately when launched from the command line, Firefox for example. Most utilities (and all the programs I've written) are tied to the shell that created them. If you control-c the command line, the program's dead. What do you have to add to a program or a shell script to get the return-immediately b...
I'm creating a python script to sort a lot of images (game screenshots). I found a way to do that in imagemagick : I know that, if a specific square of the image is the same as the reference crop, then the image is of category one. If not, I check for another crop and another category, and if that doesn't fit either, I put the image in ...
Hey Folks, how can I remove an element of an array, and reorder afterwards? <?php $c = array( 0=>12,1=>32 ); unset($c[0]); // will return sth. like array( 1=>32 ); ?> How can I do a "rearrange" like pointing the 1 to 0 after delete (automatically)? Thanks! ...

I'm working on trying to speed up some general data processing in C. I've written several subroutines of the form: double *do_something(double *arr_in, ...) { double *arr_out; arr_out = malloc(...) for (...) { do the something on arr_in and put into arr_out } return arr_out; } I like this style because it's eas...
The website viewer would be at page A, click a link that sends then to page B, but I want them to return to page A without them noticing. When they click the link it changes the layout the viewer is browsing the site with, so the redirection code shouldn't erase or undo the cookies or whatever are stored with the link click. Thanks! E...
