ActiveX control cleanup in IEcontrol contains several other user controls which provide unicode-capable labels, command buttons, text boxes, and list boxes. Because I'm creating windows and subclassing them it's critical that they be released properly. Testing the control on a VB form I was able to rely on the terminate event but apparently IE only fires that if it's a Tuesday after a full moon and the stock market is up for the day. After some digging I found that a workaround is to use the Hide event instead and that was working great in win2k and xp using ie6 and/or ie7 but when I got to Vista it no longer fires. I've tried watching for WM_CLOSE or WM_DESTROY on the main usercontrol window but that didn't help either. I've been able to work around the issue by adding code in the html to call a cleanup method when the browser fires the onbeforeunload event but that's a real hack. Does anybody have any experience with activex controls hosted by ie7 under Vista? Any thoughts on how I can detect the user closing the page or navigating away?

Try switching tabs, and closing tabs without activating them to cover all situations.
