reading clipboard


As a newbie to javascript and asp.net 2 I have come across a problem related
to the windows clipboard.

I have written an application in vb6 which collects data and puts it on the
user's clipboard in windows. On leaving that application it opens my webpage
in IE6 or 7. The page displays a text box and the user is required to paste
the clipboard into the text box.

I read about window.clipboardData.getData('Text') and it seems an idea way
of pasting the contents of the clipboard straight into the text box during
webpage load.

My problem is that my pages are written in asp.net 2 (VB style) and I have
failed in all attempts to get the clipboard to paste to an asp.net textbox.
I realise that its a job for javascript on the client side.

What i need is something like

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs)
        textbox2.text=window.clipboardData.getData("Text");
    End Sub

I have also  tried

response.write("<script
type='text/javascript'>textbox2.text=window.clipboardData.getData('Text')</ script>");

I rather suspect that I need to make a jasvascript function but have no idea
how to make a function that returns a variable that can be picked up in
asp.net during form load

All help appreciated

Pure clientside JS (there are probably other ways):

window.onload = setValue;

function setValue(){
textbox2.value=window.clipboardData.getData('Text')

}

You set a value, not the .text. Also, you may want to break the habit of
using the IE shortcut of textbox2 referring to an element with ID/NAME
of textbox2 as it will break any browser other than IE.

Thanks Randy

I have tried adding the code in a number of ways and am still stuck
I get TexBox1 undefined

Here is my test page

<%@ Page Language="VB" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

Response.Write("<script type='text/javascript'> window.onload = setValue;
function
setValue(){TextBox1.value=window.clipboardData.getData('Text')}</scr" &
"ipt>")

End Sub

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As
System.EventArgs)

Response.Write("<script type='text/javascript'> window.onload = setValue;
function
setValue(){TextBox1.value=window.clipboardData.getData('Text')}</scr" &
"ipt>")

End Sub

</script>

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

<title>Untitled Page</title>

</head>

<body>

<form id="form1" runat="server">

&nbsp;<asp:Button ID="Button1" runat="server" OnClick="Button1_Click"
Text="Button" />

<asp:TextBox ID="TextBox1" runat="server" Height="70px"
Width="531px"></asp:TextBox>

<script type='text/javascript'> window.onload = setValue; function
setValue(){TextBox1.value=window.clipboardData.getData('Text')}</script>

</form>

</body>

</html>

document.forms['form1'].elements['TextBox1'].value

It is, partially, the IE shortcut problem. Also, don't post the server
side code, post the code the client gets.
