＇在FORM1中加入一个CommandButton?一个Label并加入如下代码
Option Explicit
Private Declare Function GetSystemMetrics Lib "user32" ByVal nIndex As Long) As Long
Const SM_CLEANBOOT = 67
Private Sub Command1_Click()
Select Case GetSystemMetrics(SM_CLEANBOOT)
Case 1: Label1 = "安全模式."
Case 2: Label1 = "支持网络的安全模式."
Case Else: Label1 = "Windows运行在普通模式."
End Select
End Sub
点击Command1就可以看到Windows是以何种方式启动的?
