    convert your page into a image

    If you send down any text the user will be able to see the source, so disabling copy and paste by any method will not really help stop the determined copier.

    The most effective approach would be to render your text in to an image on the server and send down the image and not the raw text, but before you do that there are several downsides to consider: 1) You will require capacity on your server to generate the image. 2) The data load will be higher than just text and compresion will be less effective. 3) You may also loose some caching options.

    Is there a particular reason you don't want the user to copy the text, perhaps if you can provide more details other approaches may be possible?

    Try this

    <html>
<head>
<script language="<strong class="highlight">javascript</strong>">

 function onKeyDown() {

// current pressed key
 var pressedKey = String.fromCharCode(event.keyCode).toLowerCase();

 if (event.ctrlKey && (pressedKey == "c" || 
                    pressedKey == "v")) {
// <strong class="highlight">disable</strong> key press porcessing
event.returnValue = false;
 }

} // onKeyDown

 </script>
 </head>

 <body>
   <form name="aForm">
    <input type="text" name="aText" onkeydown = "onKeyDown()">
 </form>
 </body>
 </html>

    Just copy and Paste the below javascript in your webpage:

    <script language="javascript" type="text/javascript"> 
      function disableselect(e) {             
          return false 
      } 
      function reEnable() { 
          return true 
      } 

      document.onselectstart = new Function("return false") 


      if (window.sidebar) { 
          document.onmousedown = disableselect                    // for mozilla           
          document.onclick = reEnable 
      } 

      function clickIE() { 
          if (document.all) { 
              (message); 
              return false; 
          } 
      } 


      document.oncontextmenu = new Function("return false") 

     var element = document.getElementById('tbl'); 

     element.onmousedown = function () { return false; }        // mozilla         

   </script>

    Note:If the above code not works for Firefox then add style="-moz-user-select:none" in the body tag which needs to be restricted alongwith the above code.

    When someone visits your website they receive the html/css/images/JavaScript that makes up the bulk of your site. So they already have your Content, as most browsers cache this too, to allow quicker browsing.

    Read more on HTTP here - http://www.http.header.free.fr/http.html

    So it is not quite possible to totally stop anyone that know how the http protocol works. But what you can do is to maybe listen for right clicks and stop normal end users from right clicking and saving a image etc. You can get a snippet here - http://www.dynamicdrive.com/dynamicindex9/noright.htm

    But if you are talking about protecting images/files that are selling please have a look at Protect html/php/image files from tracking as it then applies to your problem.

    This is Internet. You can't completely protect the content of the page.

    But you can difficult this task for the user.

    You can too handle keyboard and mouse inputs, like Ctrl+C or right click of the mouse.

    But remember that the user can always see the source code of the page, copy it and paste on a HTML editor.

    You can make your site in Silverlight or Flash, but this will "disable" search engines indexing.
