Windows Service with com port

[Guest]

Hello All,
I need to write VB.NET application as Windows Service with the following
functions: - the Windows Service shall be able to scan and receive data via
serial port - the received data from serial port to be saved in the text
files.
Is anybody can advice the proper way to do it?

Thank you

Thanks fot the reply Mohamed.
Now I understand how to read the serial port, but how can I make windows
service constantly check the port. Does .NET have something like MSComm
control with OnComm event?

Thanks

Hi,

The simple class that was referred to in the previous reply does not have
any event notification. You can poll it using a System Timer (easiest is
the System Timer control in the toolbox).

Or, you can use a more complete class, like the Sax Community Edition serial
control that is included in the VB .NET Resource Kit (download from
Microsoft). This one is free, and it does provide OnComm events similar to
those of MSComm.

Richard,
I checked out your web site and found NETCommOCX.ocx. Does it have OnComm
event?
