条件和消息按钮

Question

我有

if x<-1 and x>1 Then

[if that condition is not met, I want a Message saying "Hey, you need a number
between -1 and 1.]

End if

我该怎么做？

Answer 1

如果您只需要一个消息框，当x超出您的范围时弹出，请尝试： -

If x < -1 OrElse x > 1 Then
    MessageBox.Show("Hey, you need a number in the range of -1 and 1")
End If
