Hi Beth, is a great article!!!

I have a question, In the program I added a column to the database is called "Time"

How I can save the the time in this column in the same style that the data saved in the "message"?

Dim message As MessageDataSet.MessageRow = Me.MessageDataSet.Message.NewMessageRow()

message.Message = myStringBuilder.ToString()

Me.MessageDataSet.Message.Rows.Add(message)

Thanks

Your article was very helpful in helping me write my first Serial Port programming App in VB.Net (VS2005). I only infd a very funny issue - which i am unable to solve.

When I write the code similar to your code in a Windows App (vb.net) - it works fine. But, if i have to write it as a Windows Service (but ofcourse i do not call the Invoke UpdateControls - i just use the Received string from the DataReceived event for my logic). I noticed that the Windows App recieves the data correctly, and the Windows Service App receives the data but there are breaks in the data (Enter lines). I use the same ReadExisting method. I am not sure if i should use any other of the ReadMethods. Do you have any advice?

Thanks

Thank you very much Beth for the serial code. I've converted it in VB2008 for use with a container filling machine I'm designing. It's given me the insight I needed.

As this is my first attempt at a software controlled machine, the serial port is proving to be tricky. It would be good to use the serial port from VB2008 but I can't find any info on the subject. Do you know of any such document? If not, I'll just have to stick with you girl!

Thank you again,

Hee Cool stuff,

Im not good at this, so i have a question!

I want to control not only the input from a port, but also the output, i want to send out a decimal or binary number to a port. But how do i do this?

And I want to use Microsoft DLL's (Windows DLL's when possible)
