In a HTML page user should not be allowed to copy a text, but at the same time I want to give option for the user to select a particular text (for highlighting purpose). That means CTRL+C should be disabled and CTRL+A should be enabled.
Can anyone tell me how to do this?

To disable the copy and paste function in PDFs, you need to prevent the ability to select text with the cursor. If a user can't select the text, then they can't right-click and copy with the mouse or use Ctrl-C as a keyboard command.
You can't ever disable it.. users can view the source of your page so the text is always available. If you put click handlers to disable right-click, they can turn javascript off.. The best you can try to do is make it inconvenient for people to deter them, but never can you prevent them.
The onpaste attribute lets us prevent pasting into the form. Adding the autocomplete attribute as well as preventing drag and drop into the element. If you want to avoid the on{event} code in the HTML, you can do it the cleaner way: myElement.

You cannot prevent people from copying text from your page. If you are trying to satisfy a "requirement" this may work for you:

Edit: I just want to emphasise that disabling copy/paste is annoying, won't prevent copying and is 99% likely a bad idea.
