How to Export Data to Excel without hassel

Saving query to excel format could go through Microsoft Office Interop services or some third party libraries. However there is a simpler way. CSV file formats are wuite simple and one could simply read queries and save them into a text file format with CSV as the extension (myfile.csv).

The tricks would be to have the data read from database by query and write each record as a line and semicolon to separate the column vales.This is actually language independent and one could implement it by C#, Java or any other language that could execute queries on a database.

Dashed line at Java/Processing

This code is a little bit edited and re-posted again from a post I found on Processing forum. Check the source at the bottom of the post for the original post.
[java]
import java.awt.*;

float[] dashes = { 16.0f, 8.0f, 4.0f, 8.0f };
BasicStroke pen;

void setup(){
size(400, 400);
noLoop();
pen = new BasicStroke(4.0f, BasicStroke.CAP_ROUND, BasicStroke.JOIN_MITER, 4.0f, dashes, 0.0f);
Graphics2D g2 = ((PGraphicsJava2D) g).g2;
g2.setStroke(pen);
}

void draw(){
line(0, 0, width, height);
line(0, height, width, 0);
}
[/java]
