vis kun et drev eller submapper, denne kode virker med alle drev.
Jeg har en gammel ASP.Net 2.0 bog hvor jeg har lavet dette eks. jeg kan bare ikke se i bogen hvordan jeg lavet en drev liste for KUN et drev evt. Drev C.Og kan heller ikke se hvordan jeg kan lave en mappe liste af undermapper for evt en mappe og ikke et drev evt. C:/test/
min kode er flg. som virker, den viser alle drev/str. og fri plads på drevet samt mapper/submapper på de forskellige drev.
