Copy To Clipboard Problem

[Wayne Wengert]

I have an aspx page on which I am trying to copy the contents of a textbox
to the client clipboard when the users clicks a button. The button code is
as follows:
=====================================
Private Sub btnCopyToClipboard_Click(ByVal sender As System.Object, ByVal e
As System.EventArgs) Handles btnCopyToClipboard.Click

Clipboard.SetDataObject(txtHidden.Text)

End Sub

=================================================

When the button is clicked, I am getting the following error pointing to the
statement in the above sub.

==================================================

Thanks for the quick response. Do you have a pointer to any exanples of how
to do this?

Wayne,

Client clipboard is located on the client machine. Your code tries to set
your web server's clipboard. On client side you can use javascript
window.clipboardData object.

Thank you. I'll use that link and see if I can get this working.

If you have MSDN library installed, just find "clipboardData" in the
index.
Alternatively go to
http://msdn.microsoft.com/library/d...hor/dhtml/reference/objects/clipboardData.asp

You will find an example there.
