Win98 Vs Win XP

Chethan.kumta · Feb 8, 2007

To interface with external hardware circuits how to use WinXP? Means.. I want to use computer printer port for interfacing with external devices, but when I write programs for that in "C" it will not work with WinXP,, Some one suggested me that only Win98 will work for it... Is it true? Why not in XP? If works also is there any security settings I must change? Plz help...

You need to use a driver, all versions of NT (of which XP is one) don't allow direct access to hardware. You can download the one I use in WinPicProg from my site, it installs a driver DLL and comes with example code in C and VB for you.
