Answer 1

Private Sub Command1_Click()
Static a As Boolean
If a = False Then
Label1.Left = Label1.Left + 50
Else
Label1.Left = Label1.Left - 50
End If
If Label1.Left + Label1.Width + 100 > Me.Width Then
a = Not a
ElseIf Label1.Left < 0 Then
a = Not a
End If
End Sub

Private Sub Command2_Click()

Timer1.Enabled = Not Timer1.Enabled
End Sub

Private Sub Form_Load()
Timer1.Enabled = False
Timer1.Interval = 100
Label1.AutoSize = True
Label1.Caption = "欢迎使用VB"
Command1.Caption = "手动"
Command2.Caption = "自动"
End Sub

Private Sub Timer1_Timer()
Command1_Click
End Sub

Answer 2

接运行就行了
