Any Help my friends would be apperciated 

Response.Write("<Script language='javaScript'> window.open('','_parent','');window.close();</script>")

 You should not use Response.Write at all. If you're using ASP.NET AJAX, then ScriptManager.RegisterClientScriptBlock is what you should use.

am still having the same error!!

plz notice that am writing my code in the Source area .. not the ( .VB) area

i wish i can write this code in the VB area .. but there i only see the PageEvents .. i can't see any other event of my controls like the Timer in this case..is there anyway that i can get the Timer event in .vb area .. ?

Ok...you're using the timer and thus asp.net AJAX. You can't (and NEVER should for registering js) use Response.Write. Do this:

ClientScript.RegisterClientScriptBlock(TypeOf(Page), "unique_key" & DateTime.Now, "window.open('', '_parent', '');", True)

If you wish to have the script loaded only once, make the second param constant (that is, remove the DateTime.Now).

the error is no longer there .

the timer fires but it does not execute my script window.open(' ','_parent',' '); which is supposed to close the parent winodw without the prompt message.

here's what i wrote:

ClientScript.RegisterClientScriptBlock(Page.GetType, "unique_key", "window.open('', '_parent', '');", True)

any help would be appreciated my friends :)

If you are using AJAX timer than

ScriptManager.RegisterStartupScript(Page, Page.GetType, "unique_key", "window.open('','_parent','');window.close();", True)
