C#

"If the method or constructor represented by this instance takes a ref parameter (ByRef in Visual Basic), no special attribute is required for that parameter in order to invoke the method or constructor using this function. Any object in this array that is not explicitly initialized with a value will contain the default value for that object type."

I would like to be able to test that WMI is available

string serviceName = "SomeServiceName";

ServiceController sc = new ServiceController();
sc.ServiceName = serviceName;

if (sc.Status == ServiceControllerStatus.Stopped)
{
	// Start the service, and wait until its status is "Running".
	sc.Start();
	sc.WaitForStatus(ServiceControllerStatus.Running);
}

this.Send("wow@yahoo.com","yyy@yahoo.com","Copier Completed" + "\r\n\r\n"+ "Nice one");

void textBox1_TextChanged(object sender, EventArgs e)
{
... //Check the input
textBox1.TextChanged -= new EventHandler(textBox1_TextChanged);
... //Change the text
textBox1.TextChanged += new EventHandler(textBox1_TextChanged);
}

//quick and dirty, this won't work as entered, but is to provide concepts
if (entryisvalid())
{
   textbox.color=color.black;
   textbox.text = doformatting(textbox.text);
}
else
{
   textbox.color=color.red;
   messagebox.show("your input is invalid, please correct the entry in red");
}
