> If you have the source code, you should be able to use Java ActiveX bridge. it
works both ways.

According to ActiveX Bridge's Product Page:

"The ActiveX Bridge allow a component based on JavaBeans(TM) component
architecture ("bean") to be
effectively packaged as an ActiveX control, thereby allowing it to be used as a
functional
component in an ActiveX container."

So this doesn't seem to be an option (using a DLL inside Linux).

> Winmain could be another option

WinMain? Could someone use a DLL in LINUX with the help of WinMain!?
