I don't get it. You mean generating an ActiveX .exe control? (do you mean .OCX or really .exe ?)
The downside for ActiveX .exe is that they don't work with regfree manifest..
The reason I'm using a .exe ActiveX control rather that a .dll version is the .exe version doesn't need to be registered before use. Good to know about the regfree issue. I was just playing around with the idea of using VB forms as controls and interacting with them from Script BASIC but IUP as a cross platform native GUI is the better solution. Using VB to create the IDE is a good example how I plan to us your library in the future.
