Detect pop up blocker

[venerable bede]

Does anyone know if there is a way to detect if pop up blockers are installed ?

My Intranet ASP.Net applications always start with a pop up to remove navigation buttons from Explorer and I need to be able to detect if they are enabled so I can inform the user.

I'm no ASP expert, but I've seen it done in Java.. I get a message sometimes with proprietary payroll stuff at work saying "Your computer has blocked a popup, click here to open it"

however, it's a Java window, not an actual Explorer window.

The cannot be done directly with ASP.NET.
As conipto said, you can use JS. Not sure how mind you.

Do you not get a warning message that a popup has been blocked?

You do it by opening a small 1x1 window and closing it.

 var testwin = window.open('','','width=1,height=1,left=0,top=0,scrollbars=no');
 if(testwin)
    var hasblocker = false
 else
    var hasblocker = true
testwin.close()

Then check the value of hasblocker.
