Problem med Paralellport
Hej!
Håller på att bygga ett inbrottsalarm med en mikroswitch och har tänkt koppla denna till datorn via Paralellporten. När strömmen bryts (mikroswitchen öppnas) så ska datorn känna av detta. Frågan jag har är hur jag ska kunna programmera VB 6.0 att läsa av paralellporten. Jag har Något kallat DLPortIO men jag får inte riktigt koden att funka.
Min kod:
Dim Value As Long
If DLPortIO.DlPortReadPortBufferUchar(Val("&H301"), 0, 0) = 16 Then
DLPortIO.BAS (inkluderad och fin)
