Hei! i have few simple applications with visualc++, never made an .dll file, but.. my plans are to make an fullscreen graphics .dll class with dx7 and visualc++ and to use this .dll with JavaSE applications, is this fully compatitive or is there limitations on c++ on Java ?? ---- JariTapio / Helsinki HomePage : www.EuroJari.net [Edited by - JariTapio on November 10, 2006 9:29:59 AM]

How are you planning to create the interface between C++ and Java?

In terms of coding you shouldn't have any problems with JNI, just make sure the virtual machine you will be running on can support it.
