Simple concatenate question on how to add an email address

Simple question for a newbie about concatenates. I have three text boxes on a form. txtboxFirstName.Text  txtboxLastName.Text  txtboxEmailID.Text .  The end result I am looking for is to concatenate the third text box with values from the first two text boxes. I have a very simple piece of code in my txtboxFirstName with the following.

txtboxEmailID.Text = txtboxFirstName.Text + txtboxLastName.Text

The result of this gives me the following output in the txtboxemailID.text:  JaneDoe

So far this works as I need it to. Now what I want to do is at the end of the last name add our email address so the end result I am looking for in the txtboxEmailID.Text is :

My thought was to add another text box called txtemaildomain and have this on the form load:

txtemaildomain.Text = ""

Then simply hide that textbox on my form and do the following: txtboxEmailID.Text = txtboxFirstName.Text + txtboxLastName.Text + txtemaildomain.Text

What is the proper syntax or more efficient way to add the address to the end of the last name? Thanks in advance.

Instead of another textbox you could use a constant in the code.
Const strDomain As String = ""

Open in new window

You could then use this to get the full email address.
txtboxEmailID.Text = txtboxFirstName.Text + txtboxLastName.Text + strDomain

Open in new window

Another option would be to use My.Settings to save the domain as a property of the application.

One advantage of that would be that it gives you the possibility of allowing the user to change the domain if required.
