if you want to program paralel port in visual basic 6.0 to windows xp. you must use inpout32.dll because windows xp block access paralel port with firewall if you use instruction port assembler in visual basic. so i will give u simple program to use file inpout32.dll in visual basic 6.0. before you are programming in vb, you must place inpout32.dll in folder where you save program or in c://windows/system32. then you must initial inpout32.dll in your program
so
type in your program this instruction
Private Declare Function Inp Lib "inpout32.dll" _
Alias "Inp32" (ByVal PortAddress As Integer) As Integer
Private Declare Sub Out Lib "inpout32.dll" _
Alias "Out32" (ByVal PortAddress As Integer, ByVal Value As Integer)
'after initialisation out and inp we can use out and inp in visual basic 6.0 so we can use example:
Private Sub Command1_Click()
Out Val("&H378"), Val("&H" & Text1.Text)
End Sub
Private Sub Command2_Click()
Text2.Text = Inp(Val("&H378"))
End Sub
