Intermittent 'access denied' error when writing to popup 1

[tcstom]

Hi everyone,

I have an ASP.NET application which uses a Javascript event on a button click to open a popup window. The window initially loads 'about:blank' then I write HTML to it manually using a Javascript function. In 98% of cases this works fine, but just occasionally (and as far as I'm concerned with no other environmental variables changed) the script fails with an 'access denied' error when accessing the popup window. This would make sense if it happened all the time but it is only occasionally. Any ideas why? The app is running on an internal network is that helps?

Do you open the window with any particular name? If so, try removing the name and seeing if that works.

Hope this helps,
Dan

Thanks, I'll give it a go. I do open it with a name and also assign it to a variable. Do you mean just use an empty string as the name?

That's the one, yup.

I'll let you know how it goes. The problem is intermittent anyway so can't be tested directly but I'll post back if it persists.

Now I've removed the window name, suddenly I'm getting problems with a popup-blocker. I think I'd beeter explain further what I'm doing...

I need users to upload a CSV file which is processed on the web server with data being added to a database. I then need to inform the user of any errors. The 'Upload CSV' button opens a popup window which display a 'Please Wait' message while the parent window refreshes as part of the HTTP POST. When the page has re-loaded it contains a startup script that re-locates the popup window (by re-opening it) and writes the results to it. It's this last step that gets blocked by the popup blocker, presumably because it's not a user action that re-opens the popup window.

Any ideas? Maybe is there any other way to re-locate a popup window after the parent has refreshed if you know it's name (other than doing another window.open())?

I'd simply stipulate that users need to exclude your site from popup blockers if they want full functionality.
