Rather dumb simplistic question.
I have an aspx 1.1 application that runs in its own pop up window.
I have a close window button on my aspx application with
on click event of:
Response.Write("<script language='javascript'> { self.close() }</script>")

My simplistic question is can I get the application to simply
close "with out the message box requiring a yes or no" to close.
Again my application runs in its own pop up window.

window or self .close() should be enough.

So you are getting some kind of alert window? What are the details? You shouldn't be getting any alert window under normally opened windows. I think I know what you are referring to however.

Try the following javascript:

window.opener = top; window.close();

I think the problem lies with when the browser sees window.opener == null. It recognizes this as the topmost window and prompts for close confirmation. By setting the opener, you trick it so it doesn't prompt.

Thank you very much.
Yes I was getting an message box upon close.

I now no longer get the message box.
The following worked very well in my aspx close button event:

Response.Write("<script language='javascript'> { self.opener = top; self.close() }</script>")
