These are some prototype methods to handle class names in html elements. As you all should know, a html element can have more than one class name.

This is part of my dom handling toolkit. Check it out and use it at will.

Cheers

This code allows you to set the "opcity" style attribute on a element without affecting it's content.

Just call the function for a specific element or to all elements of a given classname after the document loads.

Examples and advanced usage here...

Simple set of functions for capturing and manipulating the className member of an HTMLElement

A simple implementation of IServiceProvider for use in plugin style architectures.

I like to have these two methods in my toolbelt, even though it's syntactic sugar, I think it aids clarity.

This little number will allow the contents of other pages to be included or embedded into the rendered HTML of an aspx page. Using the WebClient class from the .NET framework, you can conditionally load pages, even manipulate the HTML before it is rendered and in this example, fill in forms and execute javascript actions.

The following example shows how to auto-login to an Exchange Server - this was something requested for inclusion into our portal, but I left out the logic that pulls/decrypts the real password - for obvious reasons.

Enjoy!

This is a PHP and JavaScript Image gallery that I created. There are 2 uses for this.
1.) You can save it as index.php and place in a folder containing images and it will display the images in that folder.
Example:
place index.php in images/folder
http://yoursite.com/images/folder/
This will display all images in that folder

2.) Pass in the path to the folder to display in the url
Example:
Save as imagegallery.php
http://yoursite.com/imagegallery.php?path=images/folde

Adds any character at the given index of a string.

NOTE: Count starts from 0

This simple function simply removes the character at the given index from a string.

NOTE: The count starts from 0

create a random string of 16 chars

This snippet allows an aspx page (c#) to accept URL parameters to allow styles or script to be dynamically appended to the rendered page.

I wrote this simple snippet to allow one of our vendors to accept a style override so that their application would morph into something more closely resembling our own portal application. Please see screenshots for clarification.

Function that splits a given string into sections based on the allowed length for a section. Does not split words up. Splits string on Space character (can be set to another character)

To create a chatprogram in java we need 2 classes one for Client and one for Server from which the client will be able to connect and exchange text messages. to compile the code simply type these commands in command prompt window:-
1)ipconfig(memorize the Ip address)
2)javac client.java
3)javac server.java
4)java server 10.69.23.203 (You need to type your own ip address)
5) After this you need to open another command prompt window(Make sure the server command prompt window is also open). now type:
java client 10.69.23.203
Thats it.
if anyone have any problems please post a comment and i will answer all of your questions or if you are having trouble in compiling.

This class intended to collect TODO comments from java/c++/etc source files.

What is Dijkstra Algorithm? click on the link above and first understand what the algorithm is all about. in short it calculates the shortest path from A to F or vise versa. This code i can guarantee is the simplest and easiest code to understand. just search on google and try to compare this code and other dijkstra code and you will see what i am talking about. i spent alot of time myself and my instructor to guide me on the rite path.
http://en.wikipedia.org/wiki/Dijkstra%27s_algorithm(Description)
to see how the algorithm really works go on this website it tells you step by step how to update the cost and which path to choose.
http://renaud.waldura.com/doc/java/dijkstra/
Please give some time to understand the algorithm first and then you can see my code. if you done understand the algorithm it is very useless. i know alot of people need Dijkstra algorithm in java for their HW assignment or Test. i am giving you the solution step by step. anyone who wants to understand please go to the url i have posted above and once you have understand then run the code and for those people who just want to copy so that they can get 90% in their test No Problem Here it is .
First open a notepad and name that file anything like data.txt or datas.txt and make sure the file looks something like this and in this format.
0 3 100 5 100 100 (100 represents infinity)
3 0 6 7 7 100
100 6 0 5 5 3
5 7 5 0 1 100
100 7 5 1 0 2
100 100 3 100 2 0
i name this file as a data.txt file. i have 6 nodes. and A is always the starting node which has the cost of 0 so by looking at the first line i
know that A to A have distance 0, A to B is 3, A to c is Infinity, A to D is 5, A to E is Infinity(means no edge connected with A), A to F is Infinity.
for second line(B to A is 3, and then vise versa) and for the 3rd line it starts for C and etc..
save the txt file by any name and then copy the code which i have posted and then to run type this:
javac routing.java
java routing data.txt
you will get the output. i will say this one more time understand how the algorithm works or ......................

Two very usefull functions to have around.

(note: dollarfy requires commify to work)

Here's a basic function for debugging any kind of PHP variable. It allows for "invisible" or "visible" output--that is output in HTML comments or within visible HTML tags. It also supports customizable "containers" which lets you easily edit the look of the visible and invisible blocks. Examples in code below.

I use this function when passing an array to a function being called from setTimeout();

If anyone has tried using the .NET Graphics API, they know that replacing pixel colors takes a long time to complete. I did some research and found a good source. This code will adjust the color to greyscale by Binary.
The page is http://www.navicosoft.com/software_articles/softwares_articles_index.html for more information. It is under Basic Image Processing in the list of articles.

If you're an IE user you may have noticed that when you hover on a medium to large sized image, a toolbar appears in the corner of the image. It's basically useless as it accomplishes nothing that can't be done with a right-click.

Luckily, Microsoft has included a way for webmasters to disable this function.

Similar to Perl's CGI::escapeHTML(), though (because we can!) this adds it as a method to all String objects.

This code was something I used to monitor the keys that where press while a user would be entering text into a text box in my application. I monitored and watch for the user to hit the "Enter" key and then perform some task. Handy code for chat applications.

Turns any string backwards. If you input "Test" it gives out "tseT". Hope it's useful.

The snippet shows how to use it.

The modus operandi for this is similar to that taken by PHP's implementation of such functions. It's comparitively memory-intensive, but is much faster than running a whole bunch of tests.

Basically, you set a mask -- an array of 256 null bytes -- and set those that correspond to characters you wish to trim. Then, rather than having to test if a character is in the set of characters to trim(O(n), or linear time on *ws), you just test once (O(1), or unit time) to see if the byte in question is set.

And of course, to trim(), you just wrap trim() around both ltrim() and rtrim().

One point of caution: these functions trim in place, so copy strings before trimming them. (Of course, if you usually want access to both pre- and post-trimmed strings, you could always make these malloc() a new string and return a pointer to it . . . )

Generates select boxes, text boxes, check boxes and radio buttons. Via a handful of functions.

Generates a tree view within a dropdown select box.

Generates an 88 character secure hash string for the passed in strings.

A basic employee class

This snippet effectively reads an XML document using XPathDocument (read-only) instead of using the DOM. This snippet returns the full element values in between elements. For example:

root element
code element
This is a test.
/code element
/root element

GetXmlString("/root/code"); //returns 'This is a test.'

Write a set of bytes into a 'so-called' binary file. The point is that we use BinaryWriter here and we have a byte array as input.

This function loads an File into an String.

This function provides the reverse of a string. It is constructed using string builder because strings in .NET are immutable, while stringbuilders are not. Therefore large strings could be slow to reverse if a regular string was used for the working value that is returned.

This snippet generates a secure hash string using VB.NET

One of best and unknown built in string function included in .NET is String.Split(). It has come in quite handy for my in the last 2 years that I thought I'd share. Pretty basic example here...and for my first post, I thought I'd throw in a little File IO (for free of course)! This was written in .NET 2.0 and it will take little to no modification to make it work in 1.0/1.1.

A quick and simple function to dump a variable (array, object, string, int, etc) out into -formatted output for a web browser.

If the variable is an array or an object, you can have it returned into the another variable for later processing (i.e., through templates or e-mail). Due to lack of free time, if the variable is not an array or an object, it will ignore the $return value and print directly to output.

Future revisions will add the above mentioned functionality.

This function is useful in helping to deter spam bots by obfuscating things such as e-mail addresses and URLs that are displayed on a web page. While it's not 100% fool proof, it does offer some protection.

Example:
$email = html_entitize('foo@baz.org');
/*
Outputs foo@baz.com
*/

A function to determine if the input filename is valid on Win32 platforms (that is, it does not include invalid characters, such as :\?...)

Write a set of bytes into a so-called binary file. The point is that we use BinaryWriter here and we have a byte array as input.

Set the read-only attribute of a file to true or false.

Restrict input to alphanumeric and uppercase

Put a break in a tooltip (limited chars)

This function will run all functions that are to be executed one by one on page load with specified/added orde

Add rows into a table dynamically using js,DOM

Using styles we can add scrollbars for large table where the space is a constraint

Set a word or phrase in an input field, clear it onfocus

This is a function that receives a dataTable and return it in a pivoted way.

Gets a regular expression that'll search for any regexp pattern specified in the parameters.

Gets the rightmost substring, of the specified length, from a String object.

This shows how the computed style of each node differs from the computed style of its parent. The root element, which has no parent, is instead compared against the root of a blank HTML document.

* create a new bookmark called "compute styles" in your firefox toolbar. Place the snippet code in the location field of your "compute styles". click the compute styles bookmark, then click an element on the page with the crosshairs.

Simple loop through datatable

Sometimes you need to remove slashes from POST variables which could contain arrays. The standard slipslashes-function only takes a string as parameter.

This function removes slashes from both a simple string and array variable.

Fixed the regular expression to check for more strict requirements.

this is a css to style a definition list to get a calendar list type.

See the final render.

This function calculates how many lines will text occupy.
Example (simple):


$string = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Phasellus tincidunt posuere dolor";

$num_lines = how_many_lines(10, $string);

It accepts a third, optional, parameter $options, that allows you to change behaviour. $options should be array. Following configuration options are available:

'white_spaces' - default: array(' ', "\t") - array of chars, that should be treated as whitespace.

'new_lines' - default: array("\r\n", "\n") - array of strings, that should be treated as newlines. For example, for HTML you can set 'new_lines' => array('');

'force_line_breaks' - default: true - force wrapping, when the token is longer than width, or not. If set to false, and token cannot be fitted into $width, function will return false;

'callback' - default: null - callback function for determining character width. Must accept at least one parameter - $char

'callback_params' - default: array() - optional additional callback parameters

'char_widths' - default: null - associative array in a form $char => $width, which contains char width. If $char is not found in the array, it's width is defaulted to 0.

Format Bytes

Remove newslines from a string.

If you have ever written a website or java application where people paste stuff in from Word, you are likely to have hit the problem of Word using high ascii chars for "open quotes", "close quotes", reg symbol, etc...

This java class (with a single static method) can replace the most prevalent of these with normal ascii values
