Option Explicit
Private Enum Execution_State
ES_SYSTEM_REQUIRED = &H1
ES_DISPLAY_REQUIRED = &H2
ES_USER_PRESENT = &H4
ES_CONTINUOUS = &H80000000
End Enum
Private Declare Sub SetThreadExecutionState Lib "kernel32" (ByRef esFlags As Long)
Private Sub Form_Load()
SetThreadExecutionState Execution_State.ES_SYSTEM_REQUIRED Or Execution_State.ES_DISPLAY_REQUIRED Or Execution_State.ES_CONTINUOUS
End Sub
以下c#代码却非常管用：
public partial class Form1 : Form
{
[DllImport("kernel32.dll")]
static extern uint SetThreadExecutionState(uint esFlags);
const uint ES_SYSTEM_REQUIRED = 0x00000001;
const uint ES_DISPLAY_REQUIRED = 0x00000002;
const uint ES_CONTINUOUS = 0x80000000;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
SetThreadExecutionState(ES_CONTINUOUS | ES_DISPLAY_REQUIRED | ES_SYSTEM_REQUIRED);
}
}
期待高手，不吝赐教。
