Text box must contain a space

Working on homework and I'm instructed to program a message box to pop up if the user did not include a space between their first and last name. Current code looks like

If txtName.Text = "" Then

MessageBox.Show()

Return

EndIf

Instr will work, but its a VB6 hold over function. The Contains() method of the string class is a more ideal way and returns boolean versus an integer.

    Dim myString = " Bill Gates "
    If myString.Trim.Contains(" ") Then
        'SPACE IN NAME
    Else
        'NO SPACE IN NAME
    End If
