if i were you, i will go to msdn.microsoft.com or some such source and figure out the calls and techniques necessary to perform the function. Eg How to do deal with a Serial Connection, how to deal with a Parallel connection and so on. Once i have an idea about the type of calls etc, then i'd go figure which package enables the use of those calls. then perhaps you may decide there are better (and easier) ways than to use Win32 API "Fran�ois LAUGIER" wrote in message news:a5j54l$5he$1@wanadoo.fr... > hi > i have to do a project which have to enable 2 computers to transfer files > with serial or parallel connection. > I 'm ennoyed by win32ada package. > What is the best way to use it? > I know my question isn't sharp but I don't really know what i am talking > about for the moment and also i don't want to ask u to make my work. > Thanks for answers > fran�ois > >
