Windows 7 Standby/Hibernate Phänomen

[schwa226]

Danke!

Habe es einmal so versucht:

Delphi-Quellcode:

procedure RegisterPowerSettingNotification(hRecipient : hwnd; PowerSettingGuid:  PGuid; Flags: byte);stdcall;external 'user32.dll';


Procedure RegisterForPowerNotifications(hwnd: hwnd);
Const

  GUID_POWERSCHEME_PERSONALITY: TGUID =      '{245d8541-3943-4422-b025-13A784F679B7}';
  GUID_MIN_POWER_SAVINGS: TGUID =            '{8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c}';
  GUID_MAX_POWER_SAVINGS: TGUID =            '{a1841308-3541-4fab-bc81-f71556f20b4a}';
  GUID_TYPICAL_POWER_SAVINGS: TGUID =        '{381b4222-f694-41f0-9685-ff5bb260df2e}';
  GUID_ACDC_POWER_SOURCE: TGUID =            '{5d3e9a59-e9D5-4b00-a6bd-ff34ff516548}';
  GUID_BATTERY_PERCENTAGE_REMAINING: TGUID = '{a7ad8041-b45a-4cae-87a3-eecbb468a9e1}';
  GUID_IDLE_BACKGROUND_TASK: TGUID =         '{515c31d8-f734-163d-a0fd-11a08c91e8f1}';
  GUID_SYSTEM_AWAYMODE: TGUID =              '{98a7f580-01f7-48aa-9c0f-44352c29e5C0}';
  GUID_MONITOR_POWER_ON: TGUID =             '{02731015-4510-4526-99e6-e5a17ebd1aea}';

Var
  DEVICE_NOTIFY_WINDOW_HANDLE: Byte;
Begin
  DEVICE_NOTIFY_WINDOW_HANDLE := 0;

  RegisterPowerSettingNotification(hwnd,
    @GUID_POWERSCHEME_PERSONALITY,
    DEVICE_NOTIFY_WINDOW_HANDLE);

  RegisterPowerSettingNotification(hwnd,
    @GUID_MIN_POWER_SAVINGS,
    DEVICE_NOTIFY_WINDOW_HANDLE);

  RegisterPowerSettingNotification(hwnd,
    @GUID_MAX_POWER_SAVINGS,
    DEVICE_NOTIFY_WINDOW_HANDLE);

  RegisterPowerSettingNotification(hwnd,
    @GUID_TYPICAL_POWER_SAVINGS,
    DEVICE_NOTIFY_WINDOW_HANDLE);

  RegisterPowerSettingNotification(hwnd,
    @GUID_ACDC_POWER_SOURCE,
    DEVICE_NOTIFY_WINDOW_HANDLE);

  RegisterPowerSettingNotification(hwnd,
    @GUID_BATTERY_PERCENTAGE_REMAINING,
    DEVICE_NOTIFY_WINDOW_HANDLE);

  RegisterPowerSettingNotification(hwnd,
    @GUID_IDLE_BACKGROUND_TASK,
    DEVICE_NOTIFY_WINDOW_HANDLE);

  RegisterPowerSettingNotification(hwnd,
    @GUID_SYSTEM_AWAYMODE,
    DEVICE_NOTIFY_WINDOW_HANDLE);

  RegisterPowerSettingNotification(hwnd,
    @GUID_MONITOR_POWER_ON,
    DEVICE_NOTIFY_WINDOW_HANDLE);
End;

Jedoch auch keine Meldung zu meinem Fenster das ich mit AllocateHWnd mache

Hast du vielleicht einen Tipp wo du das gefunden hast?
