急急急

Answer 1

用二个按钮：
Private Sub Command1_Click()
Image1.Visible = False
End Sub

Private Sub Command2_Click()
Image1.Visible = True
End Sub

Private Sub Form_Load()
Command1.Caption = "隐藏"
Command2.Caption = "显示"
End Sub

用一个按钮：
Private Sub Command1_Click()
If Command1.Caption = "隐藏" Then
Image1.Visible = False
Command1.Caption = "显示"
Else
Image1.Visible = True
Command1.Caption = "隐藏"
End If
End Sub

Private Sub Form_Load()
Command1.Caption = "隐藏"
End Sub
