Are you using an ActiveX control or a Browser widget? What version of
Eclipse/SWT are you running against?

Sounds like:

Have you had any success with the latest version of SWT?

You say that the version of SWT you were using is 2.0.0 but your dll version
is from 3.0 RC4 (just prior to the final release of 3.0). Are you sure you
are using 2.0?

There is a good possibility that in some call to OleAutomation.invoke() you
are passing invalid parameters. Your stack trace should point out which
call to OleAutomation.invoke is failing. You need to be careful when the
argument is null. Some ActiveX controls do not check for null before
dereferencing an argument which will result in an access violation.

The fact that you sometimes get errors in OS.FindWindowW is very strange
because SWT does not call this OS function. Are you calling this in your
own code?

Hello,

Today i've found the problem but not the solution...
Its not easy to explain but i try:

- i've an ActiveX on the top of the microsoft IE Explorer
- we use the Window.external.Do to send event to the activex wich is
handled in my application in using oleListener SWT object
- my SWT close the oleControlSite activeX
- my SWT create a new instance of the activeX and launch an URL
- On load of this url a javascript is executed and Window.external.Get is
exezcuted
- new swt oleListener handle vent, do some process and execute a
setProperty on hte activeX

and sometimes... crash down...

Is there anything unusual about the url you have loaded - does it have any
applets, does it embed Flash or any activeX control in the web page?
