there are 2 ways to create messageboxes in VB.NET
1. The old school way. I advise you not to use this. (just showing you for the sake of letting you know)
MsgBox("This is a message", vbOKOnly, "Title")
the 2nd (button style) and the 3rd (caption) parameters are optional.
2. This is the preferable way to show a messagebox.
MessageBox.Show("This is a message", "Title", MessageBoxButtons.OK, MessageBoxIcon.Information)
the 2nd (caption), 3rd (button style) and the 4th (icon) are optional.
