How to show a popup window from another asp page?

[srivalli9]

Hi .
I have 3 asp pages.
A link in the first one creates a popup window.
A link in the popup window opens a page with 2 frames in it, top and bottom.
Now, I have a link in bottom frame of this page, which, when clicked , should give focus to the existing popup window.

When creating the popup window, I used a reference to it like...
newwin=window.open(...)
I tried to pass this newwin as QUERYSTRING to all other ASP pages.
And in the last page, i.e.,bottom frame page, I used the code like..
popup.focus() ---------- *
where popup is set to querysttring variable.... Request.QueryString("popupwindowreference")

The above procedure didnt work. it thows an error like...popup is undefined at line *

Can anyone figure out what the problem is?
Any help is grately appreciated!

Thanks you.

When creating the popup the JS variable created dies at the end of that pages life, but you give that window a name when you create it.

window.open('file.htm', nameofpopup, 'properties');

Reference the nameofpopup. If you open a new window with this name on anypage from the same window of the site and it will over right the windows contents. Try:

nameofpopup.window.focus();

All though I don't know how supported window.focus is cross browser.
