The if-then-else statement provides a secondary path of execution when an "if" clause evaluates to false, the ELSE part will be executed.
Syntax:
If <> Then
Block of the statement1
Else
Block of the statement2
End If
If the condition is TRUE block of the statement1 will be executed. If the condition is evaluated FALSE block of the statement2 will be executed.
Example
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim a As String
a = InputBox("Enter text")
If a = "" Then
Me.Close()
Else
MsgBox("Welcome " & a)
End If
End Sub
End Class
