HI I have to write a user friendly application which controls a device via the serial port. I have to supply this app to our customers, so My primary target is MS-Windows :-( but I prefer if it was cross platform (i.e. runs on linux and other OSs) which programming language is easier ? which do I choose ? (Visual Basic ? Visual C++ ? Visual J++ ? JDK ? Delphi ? DJGPP ? other ?) I Know C, C++ very good I used to program with pascal so I can do it too I have some knopledge of java programming (did simple apps) I used to program basic on my Sinclair spectrum thanks Erez.
