Hi,   I'm kinda still learning to code, so be aware! my errors could be VERY BIG

the thing is,  i want to control the data pins on my LPT1 (parallel port)  so,  I'm using the io.dll as suggested by Themuzz  with the Command:  Call PortOut (888,1)

so, here's the code i use to activate a pin:

code:

---

Interop.Call("C:\TEMP\SCRIPTS\LPT!\io.dll", "Call PortOut", 888 , 1 );

---

i came to this after several attempts that the code was wrong and didn't allow the script to initialize..     now,  no errors appear,  but.......    the pin is still off...

I've checked it and this doesn't work...  the pin 2 doesn't turn on..

so, my last chance is to ask someone here for help...

all i need is this code to work so i can get my code up and running...

i have it already working to start applications remotely,  but if i can make this work i could be able to turn on and off lights, radio, tv, heating, etc...

PS:  it also would be nice  if you could tell me whats the command to turn off one pin    

Maybe in the path it should be LPT1 not LPT!?

Ummm maybe thats the path to the file?

Did you actually code the DLL? if so if you put it in an exe does it work?

I didn't know you could have spaces in function names...

yeah, according to this site

http://www.geekhideout.com/iodll.shtml

the function is PortOut, you dont need the "Call "

ok, i got something from a web using io.dll but in VB,   the call the function PortOut with its proper value, like, port is integer and Data is byte

code:

---

Private Declare Sub PortOut Lib "IO.DLL" (ByVal Port As Integer, ByVal Data As Byte)

---

maybe i should do something like this but in jscript....

any ideas?

As Shawnz already suggested, the function is called "PortOut" not "Call PortOut".

"Call" is the command in VB to call/start functions, just as "Interop.Call" is in msgplus!' jscript...

I'd also suggest to read the documentation for this DLL first (follow link given by CoolDude). Also you need to call IsDriverInstalled to make sure the other functions and procedures can be used. etc...

yeah, sorry,  my mistake...    anyways..     with the code like:

code:

---

Interop.Call("C:\TEMP\SCRIPTS\LPT!\io.dll", "PortOut", 888 , 1 );

---

it doesn't work... 

any ideas?

1) Make sure the driver is initialized and can be run. See previous post and read the documentation carefully.
2) Make sure your electronics work.
3) Make sure you readout the correct pin.
4) Make sure the lpt 1 port is at the address 0x378. Check your bios and Windows settings...

Ok,  i've checked everything except if the driver is initialized and can be run..    i don't know how...

i mean,  reading the scripting documentation is how i got this code...       i mean,  it should work with this right?
