自己按照代码加控件和改代码内容
是根据别人的改的

回答2:

RANDOMIZE

A=INT(RND()*

回答3:

RANDOMIZE

A=INT(RND()*50+1)

PRINT A

回答4:

先做3个Label
Private Sub Command1_Click()
Randomize
Label2.Caption = Fix(Rnd * 45)
Label3.Caption = Fix(Rnd * 45)
Label4.Caption = Fix(Rnd * 45)
If Label2.Caption = 6 Or Label3.Caption = 6 Or Label4.Caption = 6 Then
Image1.Visible = True
Else
Image1.Visible = False
End If

End Sub

Private Sub Command2_Click()
End
End Sub
