Well, you can make it a bit harder than it would normally be by putting a copy protection on the CD, but when searching for the keywords "cd copy protection" on Google, most links are about how to get round these things... Also of course, it's a money issue - are you prepared to pay for the protection and if so how much?
For a little more information on CD copy protection, check wikipedia. They have a few links at the bottom, so as to inform yourself about the various commercial protections there are.
The only real, 100% secure way however to prevent people from copying any data from a CD is not creating the CD in the first place.

use USB CDROM and keep it in lock and key when u dont need it.
additionally u can make USB storrage enabled/Disabled by making changes in registry. If you want to test this I will provide the tips in next write..

You can not simply Can not protect your s/w CD from being copied like this.
YES!!! and if you got any working solution on this let me know, I would like to show you that I can break it.
Trust me you can only give a legal !! Warning !! that CD is copy protected and so and so blah blah .... Technically there is no way to really protect it.

[Ali Rizwan]

But i think i can do it programatically.
And i will and i m sure that nobody can break that copy restriction.


And i ll also send that thing to you.

I did not say " YOU CAN NOT PROTECT UR PROGRAM"
What I said is : "You can not technically prevent any one to make duplicate of any CD's"

There is no way to prevent a person from making a copy of the cd. If there was Microsoft, the film industry, the game industry, ect. would be doing this. You can make it harder for a person to copy the CD, but the commercial products are very expensive. You need to do a cost/benefit analysis. How much is protecting that cd really worth, and if someone really wants to copy it they'll still be able to do so.

When we call copy command what happens?????
That file copies into clipboard. Right.
If we clears the clipboard by checking that files. When we detect that the file in clipboard is from the cd we can delete it from clipboard. Can we????
when that thing is not in clipboard how it can be copied to some place.
In such case the only thing is that user will make a virtual drive of that cd. But we can also restrict that thing by detecting the virtual drive using registry when some virtual cd software run it shows a msgbox for copyrights and then closes the programe. For this we need to make a programe which will run automatically when cd is inserted. I think using this idea we can restrict copy from CD.

Is this idea can be done practically????

NO NO NO....
its simply of no use.
First of all Copy do not take files on clipboard. IT takes file INfo on a clip board.
Secondly there are other ways to make diskcopy which dont use copy / clipboard. (One eg. Linux dd command)
I will can tell you One REAL time IDEA by which you can prevent your prog to run by unauthorised users even if they copied the CD succesfully.
You have to contact me for this as its my profession.
