Hi madankarmukta,

Thank you for your reply. Have not come here quite a while.
I find the VB host form has keypreview setting to true, which causes the problem, make the page lose the focus. I resolved the problem.

Best regards,

Frank

I am creating a ActiveX Control which wraps the .Net Webbrowser control by Interop technology. This ActiveX control will be used in a VB 5 or VB6 Form. Seem everything is fine except that some web page is not working properly.

We have a web page which has an auto-complete dropdown list.

This auto-complete does not work, no dropdown list is showed up. However it works fine when I use .Net winform to host this ActiveX...
