Let's say we have the following function:
foo <- function(x)
{
line1 <- x
line2 <- 0
line3 <- line1 + line2
return(line3)
}
And that we want to change the second line to be:
line2 <- 2
How would you do that?
One way is to use
fix(foo)
And change the function.
Another way is to just write the function again.
Is there another way? (Remember, the task was to change just the second line)
How would you implement a search facility within an ASP.NET hybrid application? I'm really tempted to start rebuilding our Intranet application using ASP.NET MVC & Web Forms (mainly MVC though).
I know how to search the dynamic content from a database, but I'm struggling with the static content in the Views. Surely this should be an easy task with routing and a sitemap.
I'm converting database from Teradata to SqlServer. I've noticed all tables and procedures are named by the prefix "dbo." (e.g. "dbo.Table1").
I would like to know if and how I can get rid of "dbo" because it would make the conversion task a lot more easier.
here is task

I just want to popup a wait message window in rebol view, but there's no option to do so with View command as
View win: layout [text "wait"]

Unview win
will block the script until the user close the message himself which is not wanted here of course.
So how to make non-blocking view ?
Here's the objective. I have a PHP class and there are one or two of its methods that I would like to override with my own. As I understand OOP (in PHP and in general) I could write a child class that extends it and overrides the functionality of the methods in question.
However, I was wondering if this is the best way of achieving this task and if this is a proper use for child classes or if there is something better in PHP for what I'm trying to do.
I'm looking for a component to manage programmaticaly added items (div's) in a parent container.The component should scale child items. Almost like a task bar,if a new item gets added it goes in the div container.
Hi all
I Have a system. I which I need to edit the PDF in every specific evcent, for that I googled a lot and reached to conclusion that it can be achieved by first converting PDF to HTML, editting the HTML and then again converting the same HTML to PDF file.

And if anyone available with other way to achieve my task, please let me know,
NOTE: PLEASE DO NOT SUGGEST ZEND FRAMEWORK USE.
I have an activity with two buttons, start and stop. If the user press the start button a service is created using Context.startService. And the stop button calls Context.stopService.
I want the stop button to be the only way to destroy the service. Now, if i end the activity using a task manager, the service is killed as well. Is there any way to avoid this?
Hi all,
In considering several possible solutions to a recent task, I found myself considering how to get a php file that includes it's own MD5 hash. I ended up doing something else, but the question stayed with me.
Something along the lines of:
<?php
echo("Hello, my MD5 is [MD5 OF THIS FILE HERE]");
?>
Whatever placeholder you have in the file, the second you take its MD5 and insert it, you've changed it.

I need to create a vb.net program that consists of a unmovable, always on top bitmap, with no menu bar or anything, and does not show up in the task bar as program.
It needs to always start in the same place.
Essentially I need to mask a part of the screen by using a bitmap that blends into the scenery.
I am not sure which properties I need to tweak to achieve all of this.
Hi,
In Python script,for every method definition in some C++ code of the form:
return_value ClassName::MethodName(args)
{MehodBody}
,I need to extract three parts: the class name, the method name and the method body for further processing. Finding and extracting the ClassName and MethodName is easy, but is there any simple way to extract the body of the method? With all possible '{' and '}' inside it? Or are regexes unsuitable for such task?
The idea is to move all of the right elements into the left and the left into the right with an empty space in the middle. The elements can either jump over one or two pieces into an empty space.

I'm trying to think of a heuristic for this task. Is the heuristic meant to aid in finding a possible solution, or actually return a number of moves as the solution? How would I express such a heuristic?
A friend is wanting me to help her convert her flash based website to html. She has an embedded textbox with a scrollbar that is using a flower instead of a normal scrollbar.
Avoiding the obvious question of why a user would want a non-standard element to do this task, is it possible to do this without flash?

If I create a scheduled task by calling ScheduledExecutorService.schedule(), it never quits after execution, is it a JDK bug, or I just miss something?
note: doSomething() is empty method below.
public static void doSomething() {
}
public static void main(String[] args) {
ScheduledFuture scheduleFuture =
Executors.newSingleThreadScheduledExecutor().schedule(new Callable() {
public Void call() {
try {
doSomething();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}, 1, TimeUnit.SECONDS);

My Windows application GUI is accepting some required application configuration fields from the user. I need to store them of course, but I wanna hide these fields from the user.
I cannot use database to store these configs.
I want to avoid using app.config either. (No app.config encryption)
Any suggestions, Where and in which format i should store fields. (Field example is: Accepting database User credentials, Task Schedule info etc.)
Hello everyone!
So I was just wondering if it was easy to develop a very simple Firefox plugin where you could click a button, and it would execute some Javascript code!
Please note that I have never developed any kind of plugin for firefox, I just want to know if that is an easy task to do (like less than an hour)
