LPT1 and access to it

[KS]

What is wrong with the login procedure in the community forums in DOT.net C#
??????

I have tried the trick with deleting coockis 3 or 4 times but STILL I have
problems with the login procedure !

Every time I will check my quistion status I'm told that I'm logged out
properly - when I click on "Return home" to login again I se a button to
"Sign out" !!!!!!!!!! and no login button !!!!!!!!!!!!!!

What is wrong with that crab product ?????

My original problem is that I can't get access to LPT1 - every time I try I
get an exception.

The LPT1 is enabled in bios and I can see it in device management and I have
installed the DLL that enables IO.

I'm using Vista Home Premium - is something restricted here or what can be
wrong ?

What exception? What is your C# code?

What exception? What is your C# code?

I'm studying this project:

http://www.thaiio.com/prog-cgi/CshapeParallelPort.htm

When I try to run the sample code you referes to I do get an exeption:

System.Runtime.InteropServices.SEHException was unhandled
Message="En ekstern komponent har udløst en undtagelse."

Why ?

Why ?

The answer is in the "project" document (near the bottom) you are referring
to:
<snip
Every thing is ok. But as you know, this program will run only in win9x. If
your program is needed to run in windows xp and higher versions, you need to
write a kernel mode device driver.
Talking about crap, well .... this is crap...
