use clipboard in asp.net

Hello
I'm trying to use the clipboard class in my asp.net project.
But all documentation I have found on the subject requires the use of the system.windows.forms class.

From a sql-query I generate a ;-separated text that I display in a textbox. I want to have a button "copy" that copies the content of the textbox into the clipboard so that the user can past it in a document, like notepad.

Is this possible?

Thanks
Anders

No. The server and client architecture of web apps do NOT work like that.

Cander's right really, i mean, not exactly right, but close...

you can copy to clipboard using javascript, if the user's browser allows it. And so its only useful when the user accepts that he must allow your webpage access to your computer.

IE running on XP with Sp2 will notify the user the webpage is trying to access resources on your computer using active content.

And other browsers have their own quirks.

If you go to that page, and find the accepted answer by 'mplungjan' (ignore the signup to see solution, just scroll past the middle advertising), you will see he shows a javascript function which automatically copies a selected value from a listbox to your clipboard.

Throw his entire html code into a blank html file... run it in IE, when you select A, 'Alpha' gets copied to your clipboard, which you can verify by opening notepad, and right-clicking and selecting PASTE.

Cander is still of course right, its an answer, but its pretty kludgy because of how webpages are meant to be limited to access to your local machine.

Thank you.

I'll have to talk to the security-deparment since its an internal app, maybe give them a Double chocolate chip cake to make them more friendly. :)

Thanks again

Sorry, its the same code as nemaroller posted.

This effect requires the use of a command available only in IE 4.0 or better,

Code:

---

<SCRIPT LANGUAGE="JavaScript">

function ClipBoard()
{
holdtext.innerText = copytext.innerText;
Copied = holdtext.createTextRange();
Copied.execCommand("Copy");
}

</SCRIPT>

<SPAN ID="copytext" STYLE="height:150;width:162;background-color:pink">
This text will be copied onto the clipboard when you click the button below. Try it!
</SPAN>
<TEXTAREA ID="holdtext" STYLE="display:none;">
</TEXTAREA>
<BUTTON onClick="ClipBoard();">Copy to Clipboard</BUTTON>

That code is no different from what i posted, both use the exec copy command. IE6 sp2 still actively blocks it by default, requiring user to explicitly allow it. So it doesn't work out of the box.
