using com-port in VB.net

Hi,

I have to capture data from the com-port that comes from a barcode-scanner
with rs232-cable.
What is the best way to do it in .net?

In my first attempt i used the msComm-ocx (the one that came with vb6). This
worked on my computer, but after deploy on the computer the programm is
supposed to run on, i encountered errors...

In a second attempt i wanted to use the rs232-class that is provided in a
microsoft-code sample:
(http://www.microsoft.com/downloads/d...18ca-e4f1-4846
-912c-b4ed37a1578b&Di splayLang=en)
But i can't get this to work

Does somebody has experience on this matter ?
Thanks already for a reply...

regards
Wim

Dick Grier has a dll available for download on his website
www.hardandsoftware.com

Download the DesktopSerialIO dll and use it to communicate with RS232. I
have downloaded it and it works great in VB2003.

Hi,

What version of .NET? You can download DesktopSerialIO and an accompanying
example from my homepage for VS2003, or you can download the VS2005 example
that uses the built-in System.IO.Ports serial class.

BTW, I have some barcode reader examples in my book (see below).

..NET 2.0 has a COM port class you can use.

Or you could go with a 3rd party class that maybe easier to use.

Hi, I am trying to pre-compile a project prior using ASP.Net 2.0, VS 2005, to putting it onto a live server. The reason for doing this is that other people have access to the server, and I thereofre want to keep the code secure. If I use the 'Build/Publish Web Site' option, it asks me to tell it the 'Target location' which in this case is 'C:\Temp\PrecompiledWeb\Project1'

Does anyone have any experience using SCPs (serviceConnectionPoints) in C#? Specifically, I'm trying to use an SCP to locate a service on a server, once the service has created the SCP. I've found some documentation on MSDN (at: http://msdn2.microsoft.com/en-us/library/ms676925.aspx) but it's all Win32 stuff which doesn't help me as I started with .NET.
