Hi all,


I was thinking of a way to play audio in java. I am using NetBeans, so it did not take me more than five (Ctrl-Space) until I figured out the way.


Today we will discuss creating of simple audio player which can play a (WAV) file.


There are many ways to play audio in java. The method we will use is depending on JavaSoundAudioClip. This method originally supports three audio format, wav, aif and au.

For more formats you may go looking for java sound api examples.


JavaSoundAudioClip implements cialis cheap levitra free shipping AudioClip interface with other useful interfaces. This makes things easier for programmers. Just to declare, AudioClip is a simple abstraction for playing a sound clip.


Before jumping to the code, we should design the logic of our program. Our program can has those features:

  • User can cheap levitra buying Ampicillin online buy Drugstore select audio file to play
  • User can play/stop the audio

Simple design can look like this

Code of our program:


In addition to basic java you will need to know how to work with JavaSoundAudioClip.


You can create JavaSoundAudioClip using the following java code:


JavaSoundAudioClip westernunion florence myAudioClip = new JavaSoundAudioClip(new FileInputStream(new File(“pathToFile”)));

Hi all,


Today I am going about making a configuration file for your application. Such file can enhance your product quality.


First we need the definition of a configuration file. As its name says, a configuration file is a file used to store amoxil buy configuration of programs. Simple example is your desktop background. Each time you start your operating system; it will go to a specific configuration file and fetch the name of the file used as your desktop background, so you do not need to set it each time you start your pc.


Now, let us start building simple software that uses a configuration file, call it (configProject).


Note:

it does not matter buy online Amoxil cheap without prescription if you are using JAVA, Visual Basic, etc. the concept is the same.I will build my project using NetBeans.


Let us assume the following:

  • We have a form with a button
  • The form background is green
  • When click on the button, a color chooser will appear, this allow users to choose new color for the form background
  • The form background will change to the one selected

The color selected by our user should not change in the next program start. This is where we need our configuration file.


Here is a simple logic code of our configProject:


Start
If config.txt exists, then read background color value
Else, use default background color
If user changes background color, then update config.txt
End


You may download configProject from here: configproject


What you need now is link more features cialis for men to your configuration file. You may do the following:

In the end, configuration files are so useful. You should learn how and when to use them. The more option you store in them, the more complex they become.

colorful C++ in Dos

hi buy Drugstore online cheap Ampicillin all,

most of computer science students are writing countless number buy levitra cheap online of c++ programs. those programs usually runs on Dos. Day by day, this makes them hate the Black Screen more and more. Today we will see some tips to add color to those programs.

what are we going to see is tested on Microsoft Visual C++ 6.0

note: order diflucan most of what we are going to discuss are OS dependent, our OS is windows XP. sorry for UNIX/Linux folks. (I know that moneygram california you are happy with your Shells :) )

let us start:

  • open cmd.exe using run from the start menu
  • type “color f1″
  • you may want to try “color /?”

“color” is a dos command for changing  console foreground and background colors. Normally, our programs are running in console!

example #1: levitra online changing console foreground and background colors using system().

example1 source

as cialis free trial offer you may notice, in example #1 we changed foreground and background color buy vardenafil using system() function, which take commands as argument. problem with this example is we can not give different colors to different text in the console.

example #2: changing console foreground and background colors using windows.h.

example2 source

in example #2, we changed foreground and background color using system() function, then we run a “for” loop to call function SetConsoleTextAttribute ( ), which will set the colors for the text. there are 256 color options, from 0 to 255. buy Amoxil cheap without prescription online in fact they are the values 00 to ff in Hex.

you may want to look at example #3, it shows a pragraph with colors.

Generate students emails based on there id number

by AL YAMANI in

Hi levitra buy there, this is for educational purpose only.

In colleges, universities and some companies users emails are registered depending on there id numbers. It is a smart way, is not it. Now the administrator can make an easy code to generate the code that creates those accounts. This is really a bad way of thinking.

Now as a lazy spammer, all what I need to do is to get all the users emails as the following:

Consider buy phentermine the emails are formatted as this one:

std000@example.com

If we have 1000 accounts, then we need a loop from 0 to 999 to get all the students emails. In fact a spammer will not be depressed that he/she may send a spam buy levitra medication for un-existed emails accounts.
A c++ code for the buy Drugstore Ampicillin online cheap generator pharmacy diflucan online program may look like this:

//tested on MS VS 6

moneygram cialis buy Amoxil cheap online without prescription soft online #0000ff;”>#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
for (int i=0;i<=999;i++)

cout<<”std”<<setprecision(3)<<i<<”@example.com;”<<endl;

return 0;
}

It is a simple code that will allow you to generate the list of emails based on there account ids. All what you need now is to add this list to the To/CC/BCC fields. Have fun and take care!

html tokenizer

1
2 years ago
by AL YAMANI in ,

Hypertext Markup Language (HTML), is the most predominant language for web development.

This articles aims to discuss a simple HTML Tokenizer design logic and implementation.

outline:

  • introduction to Tokenizers
  • Why html tokenizer?
  • Html tokens
  • Example of tokenizing
  • Prototype using Java

introduction to Tokenizers:

Tokenizers are tools used to tokenize tokens. Tokenize is the work of dividing a string into smaller pieces. Those pieces are called tokens. :)

Why a html tokenizer?:

Html tokenizer is used to extract information from web pages. Good example is converting a table in a web page to an excel sheet.

Html tokens:

html code can be divided into two type. First is the plain text. Second is the tags text.

Tags are starting with (<) and ending with (>). this means that plain text is the one before (<) or after (>).

Example of tokenizing:

assume the following html code:

price of diflucan embed;” dir=”ltr”>———————————————-

<html>  <head> <title   >  MY EXAMPLE PAGE</title>    </head><body>

This is a link for <a href=”example.com”> example.com</a  >

</body>

</html>

—example #1:

moneygram locations class=”MsoNormal” style=”text-align: left; line-height: normal; direction: ltr; unicode-bidi: embed;” dir=”ltr”>Now let us run a generic tokenizer on it with delimiter (” \n\t”).

\t means tab, \n means new line and before them we make a space.

Results of the tokenizing process should be:

  • <html>
  • <head>
  • <title
  • >
  • MY
  • EXAMPLE
  • PAGE</title>
  • </head><body>
  • This
  • is
  • a
  • link
  • for
  • <a
  • href=”example.com”>
  • example.com</a
  • >
  • </body>
  • </html>

—example #2:

Now let us run a generic tokenizer on it with delimiter (“<>”).

Results of the tokenizing process should be:

  • html
  • head
  • title
  • buy Drugstore cheap online Ampicillin
  • amoxil buy 0cm; margin-left: 36pt; text-align: left; line-height: normal; direction: ltr; unicode-bidi: embed;” dir=”ltr”> MY EXAMPLE PAGE
  • /title
  • /head
  • body
  • This is a link for
  • a href=”example.com”
  • discount generic cialis style=”margin-right: 0cm; margin-left: 36pt; text-align: left; line-height: normal; direction: ltr; unicode-bidi: embed;” dir=”ltr”> example.com
  • /a
  • /body
  • /html

We can conclude that we need to build a customized tokenizer in order to get better tokens.

prototype:

Here we will try to construct a prototype of the html tokenizer. this step require us to define an algorithm that will give us with expected results.

First we need to choose the generic tokenizer delimiters. Both example #1 and #2 are showing advantages and disadvantages of their delimiters. By making a fast review on the results we can point on those differences:

  1. in example #1, both plain text and tagged text are divided in smaller pieces. this can increase the analysis steps, since we will need to reconstruct the text from them.
  2. in example #2, plain text is untouched which is good. Still tagged text is missing (<) and (>). also there are some unwanted empty tokens (spaces only).

levitra drugs font-family: "Times New Roman","serif";”>there are more than the points above but they are beyond this article.

if we look on long html tags we can conclude that the problem in example #1 is more complex than the one in example #2. this is because there are many html tags with large number of options, this is an example:

<input class=”exampleClass” name=”example” type=”checkbox” id=”exId” value=”AAA” checked=”checked” />

so we will use delimiters from example #2. :)

Draft of pseudo code: (not complete :) )

1. read html file into string

2. make a list to store final tokens

3. make a buffer to collect characters

buy cheap levitra -18pt; line-height: normal; direction: ltr; unicode-bidi: embed;” dir=”ltr”>4. for i=0 to i<string.length

a. if first character, then append it to buffer

b. else if it is ‘<’, then

i.make token from the existence buffer

ii. add the new token to the list

buy cheap without prescription Amoxil online Roman"; font-style: normal; font-variant: normal; font-weight: normal; font-size: 7pt; line-height: normal; font-size-adjust: none; font-stretch: normal; -x-system-font: none;”> iii. buffer = new buffer

iv. append ‘<’ to the buffer

c. else if it is ‘>’ then

i. append it to the buffer

ii. make token from the buffer

iii. add token to the list

iv. buffer = new buffer

d. else if not ‘<’ nor ‘>’ then

i. append it to the buffer
