as we have tried to follow the tutorial and killed many hours on this nice peace - it did NOT work and we have been running around the net and been looking for the "Right"
inpout32.dll - but no success at all - we run windows XP
and have posted the inpout32.dll in various places including the system32 and the project catalog but no success. The saying is SEhException was unhandled and it stops on
inp (&H379S)

Hi,
I have seen the same problem as yours, but after I get the new inpout32.dll, and save it into c:\windows\system32\drivers or c:\windows\system32\
it is working now

hello, I tried the steps in this article step by step on my VB2005 (not the express edition), I got no errors but when I click on the button there is a run time error and a VB message is shown "External component has thrown an exception." and the message is titled "SEHExeption was unhandled".
I'm using a PC with windows XP with SP2, can it be the problem?

Me too.
This worked for me:
I replaced old version C:\WINDOWS\system32\inpout32.dll
with new version from http://www.logix4u.net/
|
|
|
|
|
|
|
How i can use an event when status pins changed and response to my robot speed?

The logix4u site is down, do you still have the inpout32.dll, please share me into this email: darmayuda.b.ariston@gmail.com, I really need the DLL for my project.
Thanks.

I also need the inpout32.dll. My email is citizen_runner@yahoo.com.
Thanks

hi I'm new here,recently i'm doing my project on parallel port,using the parallel port to control my motor,i used vb 6.0, i've read the inpout32.dll,for write to the port, the portaddress was 888, whereas read from the port,portaddress was 889.
well!!! the output of the pin are working fine.now i stunt on the input of the parallel port. how do i get feedback from the input of the parallel port while it's on high(1).because i'm using sensor the track the movement of the motor.could anyone tell me what's the solution.thanks

im a beginner. , there are four pins of the 5 status pins of status port i was thinking of using. So I was thinking of only reading the result of those for 4 bit info from which to get motion info from. Only one pin is on hight is it not ?
I am wanting to get the exact position. Could you share your ideas on motion sensing please?

well basically there are 5pins of status port.4pins are on high,when they aren't grounded.which is pin 10,12,13,15.whereas pin 11 is Low.pin 11 is high when  it was grounded.so it also can be use as one reading info.
sorry for one thing i need to know before i answer your question,what thing u apply on this status pins.

I have been using a couple of 1.5 batteries to get a 3 volt source. I connect that between a ground pin and whichever status pin. What was high becomes low, low becomes high, whilst ever the battery is connected to a particular pin.
This all seems to work fine, unless all the data pins D0 - D7 are on high. Then this stops working , I dont know why just yet.

also my status port seems back to front from the example, the value returned
from status port with no connections on parallel port anywhere is 135, the exact opposite . 10000111

first check your coding,data port D0-D07 wont be affected by status port and control port.data port address was 888,and status port was 889.this is what i declared on my project.
default value of the status port was 127, which is 1111111. why you want to connect the 3v on the status pin?isnt it's supply source to other component,or else. if it is, you can use one of the data pins, data pins provide 5v, add one 1K resistor.
if you want to get exact position, there is one easy way for doing that,apply a limit switch on that position, connect it with on of the status pin, when the limit switch is turn on, then get the value to do next step.
value=inp(889)
if value = 63 then 'assumed i'm used pin 10,(binary=0111111)'
.....
end if
hope can help you.;)

ECP parallel Port. C# VS2005, win XP ,asus k8v-x se, Inpout32.dll , io.dll
Hi Experts, this may weary you but I getting nowhere. I am trying to get reliable input to the status port using external power supply. Always works great while DATA Port is low(00000000) If Data Port Low and nothing connected then Status Port Reads 135(10000111) , the status port reverts back to 135(10000111) as soon as I take away the signal voltage I have on pin/s. This seems perfect! BUT.....
If DATA Port is high(11111111) then Status Port reads 127(01111111) and I cannot use /affect status port again untill I have reset the Data Port (00000000)? This is the worst extreme of the situation. In between values on the DATA Port simply make the Status Port 'haphazard/unreliable' not sure of the pattern yet.
Im operating machinery of a sort with the Data Port and trying to get them to feed back to the Status Port what is going on

I had messed around with my notebook's LPT1 for sometime. A week ago when I developed a program that read the port, everything was fine and sweet. My LPT1 worked well. I assigned &H378 to 0, which seems to make the data port as input port, and the program read the port smoothly. But when I applied the prog (in VB 6) and install/copy some dll (incl inpout32.dll to my PC, it didn't worked. I'm still curious why it did not work in my PC. I checked all the bios setting on both but it seems that they are similar (all in ECP mode).

regarding your problem, have u copy the dll to right position>?(C:\WINDOWS\system32).
if u do, then u ca try to unistall ur parallel port on device manager.and then reinstall back.and u're assigned the port address to &H378, for input port of the parallel port should use &H379, or use 889.
hope can assist u and solve your problem.

Hi,
Thanks for the great article.
I would like to know about data input
1. Anyway to get the value of the input pin whenever the input port value is changed? without pressing the button?
2. Can we get the value from the status and control input port concurrently?
Thanks and regards
Aaron

I guess to use the timer control, and within the timers event just put the two methods to read the input.
