Pokretanje programa ide ovako:
Shell "C:\putanja do programa\program.Exe", vbNormalFocus ' Pokrece program
Kako da se ispita da li je već aktivan to ne znam. Možda neko ima ideju ako je to iz Access-a moguće.

Na adresi http://www.freevbcode.com/ShowCode.asp?ID=701 se nalazi kod za prikaz svih programa u listboxu. U modulu ćeš naći funkcije koje pune taj listbox, njih možeš otvoriti u notepadu ako nemaš vb6.

Treba da se pre izvršenja jedne procedure proveri aktivnost jedne male aplikacije.
Ako je aplikacija aktivna procedura se izvršava, ako nije prvo se ona aktivira pa se ista procedura izvršava. Sve bi trebalo da bude u pozadini tj neprimetno za korisnika Access-a.
Hvala
