.NET Forum / Languages / VB.NET / August 2006using 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/details.aspx?FamilyID=075318ca-e4f1-4846 -912c-b4ed37a1578b&DisplayLang=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. John > Hi, > [quoted text clipped - 17 lines] > regards > Wim 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).

Or you could go with a 3rd party class that maybe easier to use. Free MagazinesGet these publications absolutely FREE for up to 12 months. There are no hidden fees and no obligation.
