I have got a form in Java (Swing) loading large amount of data from the database. I want to display a progress bar while the program gets actually loaded.
How can i do it??
I am passing in command line arguments to my Lisp program and they are formatted like this when they hit my main function:
("1 1 1" "dot" "2 2 2")
I have a dot function and would like to call it directly from the argument, but first I must strip the " characters.
I tried variations of this function:
(defun remove-quotes (s)
(setf (aref s 0) '""))
to no avail, Lisp complains that "" is not a member of base-char.
Thanks!
I have an array of points that make up a line. However I need to draw the line with the width of n pixels. How can I transform that points for lines to points for polygon (or a shape) so I can directly draw it on canvas. I'm developing two program at the same time, one is j2me and another is .NET CF. j2me doesn't support drawing lines with width. Please take a look at the picture.

I am using Android HoneyComb.I need to execute some tasks parallely and I am using AsyncTask's

Hi,
I'm writing a program and I need some extra functionality from the gtk.Notebook widget, so I have taken to creating my own.
My only problem is styling my tabs so that they look like the tabs in gtk.Notebook and will change according to the user's theme.
I really don't know where to start so any advice would be much appreciated, thanks :)
I'm fairly new to programming and from learning I have seen different ways of formatting code, comments, etc; and have been recommended on different techniques.
I mostly program in C#, C++, and Java so I want to know what is the the best way to layout code so that if other people where to go through it, they would be impressed by how simple and easy to understand it is.
I would like to know the same thing for commenting as well.
I need to read a file and send the text from it to a string so I can parse it. However, the program won't know exactly how long the file is so what would I do if I wanted to use fgets, or is there a better alternative?
Note:
char * fgets ( char * str, int num, FILE * stream );

I have this parent class:
@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "BSEntity")
@DiscriminatorColumn(name = "resourceType", discriminatorType = DiscriminatorType.STRING, length = 32)
public abstract class BaseEntity {
and the subclass
@Entity
@Table(name = "BSCategory")
@DiscriminatorValue("Category")
public class CategoryEntity extends BaseEntity {
But when I run the program, I get the following error:
2010-06-03 10:13:54,222 [main] WARN (org.hibernate.util.JDBCExceptionReporter:100) - SQL Error: 1364, SQLState: HY000
2010-06-03 10:13:54,222 [main] ERROR (org.hibernate.util.JDBCExceptionReporter:101) - Field 'resourceType' doesn't have a default value
Any thoughts?
Updated:
Database is MySQL. I have also changed inheritance strategy to JOINED instead of SINGLE_TABLE. Help
In the Visual Studio output window, you can double click a line that contains a file path and line number and it automatically takes you to that location. In my program, I need to mimic this behavior and be able to click something (a button for example) and do go to a specific file and line number that I tell it to go to. Any help/suggestions would be appreciated.

Is there a script i can use to copy some particular sectors of my Harddisk?
I actually have two partitions say A and B, on my Harddisk. Both are of same sizes. What i want is to run a program which starts copying data from the starting sector of A to the starting sector of B until the end sector of A is copied to the end sector of B.
Looking for possible solutions...
Thanks a lot

I need to solve a system of linear equations in my program. Is there a simple linear algebra library for C++, preferably comprised of no more than a few headers? I've been looking for nearly an hour, and all the ones I found require messing around with Linux, compiling DLLs in MinGW, etc. etc. etc. (I'm using Visual Studio 2008.)
We're trying to script a CAD program, and this is the example for controlling the date in our design slugs, but I don't even know what language it is to know what to do with it.

The National Park Service's Natural Sounds Program collects multiple terabytes of data each year measuring soundscapes. In your opinion, what is best available scripting language to manage massive amounts of files and file types? We would like to easily design and run efficient user-friendly scripts to search for and retrieve/create copies of files that may be located in different directories according a single static hierarchy. The OS will most likely be windows. Thanks!
I am looking to start a community based on user posted scripts such as bashrc, screenrc, aliases, etc.
Does anyone know of a web application in PHP that would do that?
I am not looking for a snippet program, or a link directory.
Users can store linux/UNIX/Windows configuration files, as well as maybe an option to attach a screenshot.
