End Function
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As
Single)
SW = False
End Sub
Private Sub Form_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single) SW = True
End Sub
Private Sub Command1_Click() Dim intNum As Integer intNum = InputBox("")
If SW Then
Print func(intNum) End If
End Sub
程序运行后，单击命令按钮，将显示一个输入对话框，如果在输入对话框中输入25，则 程序的执行结果为______。
