Here is an example of something similar:

Adding JavaScript Confirm Delete Dialog to ASP Pages
http://www.gotocode.com/art.asp?art_id=78&

 Response.Write( "<SCRIPT Language='JavaScript'>")
 Response.Write( "if (document.forms['" & formName & "'])" )
 Response.Write( "document." & formName & ".onsubmit=delconf;" )

 Response.Write( "function delconf() {" )
 Response.Write( "if (document." & formName & ".FormAction.value == 'delete')" )
 Response.Write( "return confirm('Are you sure you want to delete this record? The delete cannot be undone!'); ")
 Response.Write( "}")
 Response.Write( "</SCRIPT>")


Notice the use of the 'confirm' Javascript function.

To allow cancel, set the 'onClick' attribute like this:

   Me.Button1.Attributes("onClick") = "javascript:return confirm('Are you sure you want to delete this record? The delete cannot be undone!');"

If you click 'Yes', it will post back, and if you click cancel, it won't.

If you look at the article, you will see this resulting Javascript code:

<INPUT type=hidden value='0' name='hiddenfield_name'>

<script language='javascript'>"

 if (confirm( ' + sMsg + '))"
 {
    document.forms[0].hiddenfield.value='1';"
    document.forms[0].submit();
 else
 {
   document.forms[0].hiddenfield_name.value='0';
 }
</script>
