In this tutorial we will examine an image upload form, look at PHP's file upload system, and use an uploaded image to create a small thumbnail image.Please note this requires you to use the GD2 library. You can normall allow it by changing your php.ini by removing the ; in front of extension=php_gd2.dll.PHP's built in system for uploading files allows us to create an HTML form that uses the "file" element. This is a type of HTML input tag that tells a user's web browser to display a file selection dialogue, and to include any selected file with the data sent along with a form. Code::<form action="index.php" method="POST" enctype="multipart/form-data"> <input type="hidden" name="MAX_FILE_SIZE" value="200000">"; <input type="file" name="imagefile"> <input type="submit" name="upload" value="Upload Image"> </form> Thanks,Fuad.

It can be thought of as a super Remote Procedure Call (RPC) mechanism with some basic object roots.The ScriptOpen you favorite text editor and put the following lines: Code::<?PHP $objApp = new COM("Outlook.Application"); $myItem = $objApp->CreateItem(olMailItem); $a=$myItem->Recipients->Add("admin@example.org"); $myItem->Subject="This is a test"; $myItem->Body="This is a Body Section now.....!"; $myItem->Display(); $myItem->Send(); ?> Thanks,Fuad Sat, 24 May 2008 03:16:20 -0700 Create a Cookie in ASP in Script Forums : ASP http://www.w3exchange.com/view_topic.php?pid=7924#7924 7924@http://www.w3exchange.com Topic: Create a Cookie in ASP Message: Hi,A cookie is often used to identify a user. A cookie is a small file that the server embeds on the user's computer. Each time the same computer requests a page with a browser, it will send the cookie too. With ASP, you can both create and retrieve cookie values.The "Response.Cookies" command is used to create cookies.Note: The Response.Cookies command must appear BEFORE the html tag. In the example below, we will create a cookie named "firstname" and assign the value "Alex" to it: Code::<% Response.Cookies("firstname")="Alex" %> It is also possible to assign properties to a cookie, like setting a date when the cookie should expire: Code::<% Response.Cookies("firstname")="Alex" Response.Cookies("firstname").Expires=#June 10,2008# %> Thanks Thu, 22 May 2008 02:43:57 -0700 PHP code and HTML code in Script Forums : PHP http://www.w3exchange.com/view_topic.php?pid=7878#7878 7878@http://www.w3exchange.com Topic: PHP code and HTML code Message: PHP code is not technically executed inside an HTML document. PHP is a programming language, HTML is a markup language, and the two should not cross.To accurately implement a site using php, you shouldn't need to have an HTML or HTM file! Your files should be PHP (unless you need others such as CSS and JAVASCRIPT etc). Each php file should begin with a php tag, and end with a php closing tag. Only one of each. I see many websites which just open php tags, run the code, echo the html and close the php tags - many do this multiple times in one document, which is horrendus programming and indicates the user does not know what's going on.To accurately answer your query - you should have a php file with functions for generating html code. You can then make a function which generates a header (including doctype, <html>, <head> etc), and functions such as tag (to do <p>Hello!</p>), starttag (to do <p>), endtag (</p>) and for singletons (<br/>).This will eliminate the need for a html or htm file, is complete valid php, and actually saves the preprocessor dealing with the markup language, then passing it to a browser to display on the page. Instead, it deals with the functions, and the markup language is only analysed by the browser. The correct way to program. This also guarantees your html tags are always correct :) Sat, 17 May 2008 13:10:22 -0700 The very simply way to make a image slider by Javascript in Script Forums : JavaScript http://www.w3exchange.com/view_topic.php?pid=7866#7866 7866@http://www.w3exchange.com Topic: The very simply way to make a image slider by Javascript Message: Hi all!I found that is difficult to search a simple javascript code about scrolling image slide. You can find them on Internet but they often are long and complex or hidden from us to prevent edit. I just found a simple way to resolve this. I hope it will help your editting easier to make it yours!We need 2 div tag to make a slide. ChildDiv to store image array and ParentDiv to contain Child Div.Note:Image Array's Structure: [<Image's Link>, <Image's Width>, <URL to Go>]Functions: DoSlide(), Make Slide to run. setmouse(param), set Slide play and pause when pointer over or out on images; Dr_ImgArr(); Print image array to HTML; getE(), getElementById(); DivWidth: Width of ParentDiv; MoreImage: Num Of Image on a begin of Image Array, insert into the last of ChildDiv to continue the Slide;....If you have anymore comment, please reply here so that I can make it more perfect,thank for all.Demo: http://boy.us.com/Code/slide.phpStyle Code::<style> #ParentDiv { margin: auto;

Wed, 14 May 2008 23:48:44 -0700 Thread Synchronization In Java in Script Forums : Java http://www.w3exchange.com/view_topic.php?pid=7849#7849 7849@http://www.w3exchange.com Topic: Thread Synchronization In Java Message: Hi,Threads commonly share the same memory space area, that’s why they can share the resources. Threads commonly communicate by sharing access to fields and the objects reference fields refer to. This communication type is extremely efficient, but makes two kinds of problems: thread interference and memory consistency errors. By the synchronization tool we can avoid this problem.Synchronized methods are useful in those situations where methods can manipulate the state of an object in ways that can corrupt the state if executed concurrently. Stack implementations usually define the two operations push and pop of elements as synchronized, that’s why pushing and popping are mutually exclusive operations. For Example if several threads were sharing a stack, if one thread is popping the element on the stack then another thread would not be able to pushing the element on the stack.The following program demonstrates the synchronized method: Code::public class SynThread{ public static void main(String args[]){ Share s=new Share(); MyThread m1=new MyThread(s,"Thread1"); MyThread m2=new MyThread(s,"Thread2"); MyThread m3=new MyThread(s,"Thread3"); } } class MyThread extends Thread{ Share s; MyThread(Share s,String str){ super(str); this.s=s; start(); } public void run(){ s.doword(Thread.currentThread().getName()); } } class Share{ public synchronized void doword(String str){ for(int i=0;i<5;i++){ System.out.println("Started :"+str); try{ Thread.sleep(100); }catch(Exception e){} } } } ThanksFuad Wed, 14 May 2008 03:05:30 -0700 Benefits of Ajax in Script Forums : Java http://www.w3exchange.com/view_topic.php?pid=7823#7823 7823@http://www.w3exchange.com Topic: Benefits of Ajax Message: Ajax is new very promising technology, which has become extremely popular these days. Here are the benefits of using Ajax:* Ajax can be used for creating rich, web-based applications that look and works like a desktop application.* Ajax is easy to learn. Ajax is based on JavaScript and existing technologies like XML, CSS, DHTML. etc. So, its very easy to learn Ajax.* Ajax can be used to develop web applications that can update the page data continuously without refreshing the whole page.

In multitasking only one CPU is involved but it can switches from one program to another program so quickly that's why it gives the appearance of executing all of the programs at the same time. Multitasking allow processes (i.e. programs) to run concurrently on the program. For Example running the spreadsheet program and you are working with word processor also.Multitasking is running heavyweight processes by a single OS.Multithreading is running multiple lightweight processes in a single process/ task or program. For Example, When you used a word processor you performs a many different tasks such as printing, formatting text, spell checking and so on. Multithreaded software treats each process as a separate program.Some advantages of multithreading over multitasking are: * Threads share the same address space. * Context switching between threads is usually less expensive than between processes. * Cost of communication between threads is relatively low.
