'''在模块中.声名API直接调用就可以了
Private Declare Function SystemParametersInfo Lib _
"user32" Alias "SystemParametersInfoA" (ByVal uAction _
As Long, ByVal uParam As Long, ByVal lpvParam As Any, _
ByVal fuWinIni As Long) As Long
Sub DisableCtrlAltDelete(bDisabled As Boolean)
' Disables Control Alt Delete Breaking as well as Ctrl-Escape
Dim x As Long
x = SystemParametersInfo(97, bDisabled, CStr(1), 0)
End Sub
在程序中直调接用就可以了
Private Sub Command1_Click()
DisableCtrlAltDelete True
End Sub
