How to control the Parallel port with C# 2005

[carlossan]

Hi,

Looking on the Internet, I've found many references pointing that Visual Studio 2005 provides a class to control the PC's parallel port. I can't find that class.

Any ideas please

Thanks

Carlos

What kind of "control" to you wish to exercise over the port? The only thing I can think of doing with a parallel port is sending data to it: printing.

Look at the System.Drawing.Printing namespace and see if it contains what you need.

Thomas,

Thanks for your answer. I looked at the methods of System.Drawing.Printing but it seems it doesn't provide what I'm looking for.

What I'm trying to do is to control the status of the data pins of the PC's parallel port, so I can connect there some LEDs. I've found several postings on Internet about this subject, but none of them done in VS 2005 and in those same postings I have found the comment that VS 2005 "will have" a special class to control the parallel port. Well, VS2005 is here, so I was wondering how to solve this.

Thanks,

Carlos

You can do that with Serial Ports, but not, apparently, with Parallel Ports:

System.IO.Ports

The COM objects used are still, and will always continue to be, compatible with .NET

COM is not going any where any time soon. So if you can't find what you want in .NET just register the right COM object and call it from C#
