I want to send a simple command, such as "v20" followed by a carriage control character, to a heating/cooling block connected to a desktop computer running Windows XP. I am able to get the commands to work within a terminal emulator. I want to compile a simple program that will be executed by software used to control a liquid handling robot.I've looked at the how to send strings to serial ports in visual basic page and modified that code ever so slightly to send the data that I want. However, it does not work and my heating/cooling block is not changing temperatures.
Here's what I have written:
Sub SendSerialData(ByVal data As String)
data = "n65"
' Send strings to a serial port.

Dim lpPoint As POINTAPI

Opens a serial connection when a radiobutton is selected. My question is: How can I make a message pop up saying "COM Port in use" if the radio button is selected when the com port is in use by another application? Right now, the program just crashes.
In the developing environment the computers do not have com ports, but I am working on a project for a client who does. It is annoying that when I test the program on my computers I always get the error. "The port (COM1) does not exist"
I am catching the general exeption but the debugger stops there anyway. I can press "continue" and the program resumes but I would like to clean that up and not try to open the port if the computer does not have one.
vb.net
Try
SerialPort1.Open()

Scenario: We are using a createwizard control to create users for our website. When the user has an email we simply send the user the email with their username and password saying their account has been created. Using MailMessage and SMTPClient.
Problem: When the user doesn't have an email (ex. temp employee, student) I need to be able to generate the email but have it open via the creator's mail client so that they can enter in an email themselves/see the username and password. Similar to @mailto functionality. Question: Is there a way to do this from the code behind? I have tried searching but everywhere is telling me to use MailMessage and SMTPClient which I don't need.
