Now I may be reading this wrong, but what you've just said is that your code
reads the input provided by the scanner into the keyboard buffer, and then
......puts it back into the keyboard buffer. Why?
Scanners that plug between the keyboard and the host PC require NO SOFTWARE!
just have your program ask for keyboard input e.g. a text box. Scanners that
connect to the serial port usually come with their own piece of software which
stuffs the data into the keyboard buffer and hence require NO OTHER SOFTWARE!
No VBX's/DLL's/any other expensive nonsence are required - Don't get fooled
into believing you need something you get for free!
