Wow, this sound like good news! The activex I have is not visual; it is "simply" a class that creates a thread in which a physical device is controlled through a serial port, with a particular protocol. The class then has methods like "Open channel", "Read Mesaure", and so on.
Is there any documentation I can read? I think I have to translate some header files to understand the exchanged data...or shall I use only variant ? I suppose I have to change MSWord := CreateOleObject('Word.Application'); into something related to my class; where do I discover the "name.surname" ? Thanks all! 2011/5/23 Ludo Brands <ludo.bra...@free.fr>: > If the activex is not a visual control that you want to put on a LCL form > you can use CreateOleObject.
