[AccessD] Back to Web Browser ActiveX

Yes, it's not trivial but you can get a stable MS Web Browser control automation solution by using C# (or VB.NET), and properly written apps will run for days/many hours till they will have to be restarted because MS Web Browser control is known to be a source of memory leakage...

It requires days/a couple of weeks to get accustomed with its automation -  then it becomes "your friend" ready to fulfill promptly most of your commands/tasks...

The main trick is to find a way of controlling Web Browser control from a worker thread, and it's known that Web Browser control is running in the main WinForm thread. When that task of controlling Web Browser control from a worker thread solved then you can have many web browser controls instances on one WinForm (e.g. on different TabControl tabs) all running smoothly in not blocking UI mode...

Thank you.
