Windows in Standby oder Ruhemodus versetzen

[gmc616]

Vor laaaanger Zeit habe ich mal diesen Code hier gefunden:

Delphi-Quellcode:

uses Windows;

var
  _SetSuspendState: function (Hibernate, ForceCritical, DisableWakeEvent: BOOL): BOOL stdcall;

        
function LinkAPI(const module, functionname: string): Pointer;
var
  hLib: HMODULE;
begin
  hLib := GetModulehandle(PChar(module));
  if hLib = 0 then
    hLib := LoadLibrary(PChar(module));
  if hLib <> 0 then
    Result := getProcAddress(hLib, PChar(functionname))
  else
    Result := nil;
end;

function SetSuspendState(Hibernate, ForceCritical, DisableWakeEvent: Boolean): Boolean;
begin
  if not Assigned(_SetSuspendState) then
    @_SetSuspendState := LinkAPI('POWRPROF.dll', 'SetSuspendState');
  if Assigned(_SetSuspendState) then
    Result := _SetSuspendState(Hibernate, ForceCritical, DisableWakeEvent)
  else
    Result := False;
end;

Aufruf mit:

Delphi-Quellcode:

// Ruhezustand
SetSuspendState(True, False, False);

//Standby
SetSuspendState(false, False, False);
