I tried for hours and hours to find a good, simple code to make it possible for me to open a URL or send an e-mail from a link edited in a TextBox and not assigned in a LinkLabel. The answer is very simple: Just add the following code to a click event in a button:
Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button1.Click System.Diagnostics.Process.Start(TextBox1.Text) End Sub
The contents of the text box must be http://www.something.com or mailto:firstname.lastname@example.org. Your default browser or mail application will open and perform the requested action.
