Welcome to Tips of the day! Here our some css components people asks about.
Code 1:
/* This code will effect the whole page */
*
{
/* Code here*/
}
Code 2:
/* This will place an object in center */ margin:auto; padding:auto;
Code 3:
/* This will reset basic browser stuff */
margin:0;
padding:0;
border:0;
/* usually placed between *{ /* here */} */
Hi again, everyone!
It was a long time ago I wrote something here, so now I will present my new school website I have made. This website is basically done by using JS and CSS, as a normal website. You may find the website at http://www2.katedral.se/~ib11loar/

This week was amazing, I’ve started the school! Actually, I’ve nothing to add, only that the school rocks!
Currently, I´m in Russia, the city of Kaliningrad. It´s an old city, and it has a very rich history. In meantime, I´m there, I will try to create some posts at my swedish blog here. You are always welcome!
This tutorial will show you how you can encrypt/decrypt text (string) with Java Script or JScript.
First we need a table, even called for matrix. To create a matrix I chose to combine three array-lists into one single. (Note that it also works without the combining of arrays!)
//generating 3 arrays
var _matrixA = new Array();
var _matrixB = new Array();
var _matrixC = new Array();
var _mA, _mB;
_matrixA = new Array("A", "", "", "B", "C", "D", "E", "F", "G", "H"); // 0
_matrixB = new Array("I", "J", "K", "L", "M", "N", "O", "P", "Q", "R"); // 1
_matrixC = new Array("S", "T", "U", "V", "W", "X", "Y", "Z", ".", "/"); // 2
//assign values of columns
_mA = 1;
_mB = 2;
//combining matrix
var _matrix = new Array(_matrixA, _matrixB, _matrixC); //this is the table, to get data, use _matrix[x][y]
Encryption Method:
// Encryption method
function encrypt(_text) {
var _returnVal = "";
for (i = 0; i < _text.length; i++) {
if (_matrixA.indexOf(_text.charAt(i)) != -1) {
_returnVal += (_matrixA.indexOf(_text.charAt(i)));
}
if (_matrixB.indexOf(_text.charAt(i)) != -1) {
_returnVal += (_mA); //default 1
_returnVal += (_matrixB.indexOf(_text.charAt(i)));
}
if (_matrixC.indexOf(_text.charAt(i)) != -1) {
_returnVal += (_mB); //default 2
_returnVal += (_matrixC.indexOf(_text.charAt(i)));
}
}
return _returnVal;
}
Decryption Method:
// Decryption Method
function decrypt(_text)
{
var _returnVal = "";
for (i=0; i < _text.length; i++)
{
if (_text.charAt(i) != _mA || _text.charAt(i) != _mB )//the char has to be in 'first' matrix, _matrixA
{
_returnVal += _matrixA[_text.charAt(i)];
}
if (_text.charAt(i) == _mA) //the char has to be in 'secend' matrix, _matrixB
{
i++;
_returnVal += _matrixB[_text.charAt(i)];
}
if (_text.charAt(i) == _mB) //the char has to be in 'third' matrix, _matrixC
{
i++;
_returnVal += _matrixC[_text.charAt(i)];
}
}
return _returnVal;
}

Please take a look over the code I’ve founded at http://dotnet-snippets.com/dns/calculate-crc32-hash-from-file-SID587.aspx.

Precision Helper 2.0 is very useful when you want to create a CHM (Windows Help) files. You can create new, import websites (directory), decompile an existing CHM file, etc. It can also convert your project into a single webpage, or ePub Book. It’s freaky awesome, and it’s why i’m creating a Swedish translation of it! This program has a good language support. It has both English, Czech, French, Hungarian, Polish, Russian and soon enough Swedish! 😛
Obviously is this software full of more nicer features, such as scripting interface and a very easy to use GUI (Graphical User Interface). I won’t list all features, but I strongly recommend you to visit its official website http://www.be-precision.com/products/precision-helper/.
The design of the program is much similar Microsoft Word’s, but I think it does not matter! With few words, this software is freaky awesome tool for creating CHM files! Try it out!

Currently, is my new mission, to translate a software, called “Precision Helper”. It’s very nice software, and it’s why i’m translating it! With few words, it’s free and awesome. The software can be downloaded from http://www.be-precision.com/
More information will come soon!

Please take a look of my application!
