Dosbase application on windows xp problems -


all dos base application experts here 1 thread creating. opinion issues

i found 1 problem in windows xp or windows system higher windows 98 have dos base application runs perfect on windows 98 when running on windows xp or other system showing me following error message

16 bit ms-dos subsystem

an application has attemped directly access hard disk, cannot supported. may cause application function incorrectly. choose close terminate application

as can run pressing ignore want remove error message

second thing found dos base printing printing not working properly

as prints part pause time , resume printing

so how solve these problems.

an application has attemped directly access hard disk, cannot supported.

this error means says. older versions of windows including 95/98/me gave dos programs full control on system, meaning access hardware wished -- while maintained compatibility older programs, cause entire os crash if 1 program did wrong.

the windows nt family (including xp , newer versions) runs dos programs in ntvdm (nt virtual dos machine) not have direct access hardware, , attempt programs access such things cause program terminated. of course, can ignore error, program not work correctly.
