Problem ShellExecute / CreateProcess + Wait mit Vista UAC

[hitzi]

Hallo,

muss das Handle auch irgendwann geschlossen werden, wenn ich den Code von himitsu so ändere, dass nicht auf das Ende des Programms gewartet wird:

Delphi-Quellcode:

function ExecAndWait(Filename, Params: String;
                     WindowState: Word = SW_SHOWNORMAL): boolean;
var
  {$IFDEF UNICODE} ShExecInfoW: SHELLEXECUTEINFOW; {$ENDIF}
  ShExecInfoA: SHELLEXECUTEINFOA;
// MSDN: ShellExecuteEx, ShellExecuteInfo
begin
  Result := false;
  if (Filename = '') or not FileExists(FileName) then
    exit;
  {$IFDEF UNICODE}
  if (Win32Platform = VER_PLATFORM_WIN32_NT) then
  begin
    ShExecInfoW.Wnd          := GetForegroundWindow;
    ShExecInfoW.cbSize       := SizeOf(SHELLEXECUTEINFOW);
    ShExecInfoW.fMask        := SEE_MASK_NOCLOSEPROCESS;
    ShExecInfoW.lpVerb       := 'open';
    ShExecInfoW.lpFile       := PWideChar(WideString(Filename));
    ShExecInfoW.lpParameters := PWideChar(WideString(Params));
    ShExecInfoW.lpDirectory  := PWideChar(WideString(ExtractFileDir(Filename)));
    ShExecInfoW.nShow        := WindowState;
    Result := ShellExecuteExW(@ShExecInfoW);
  end
  else
  {$ENDIF}
  begin
    ShExecInfoA.Wnd          := GetForegroundWindow;
    ShExecInfoA.cbSize       := sizeof(SHELLEXECUTEINFOA);
    ShExecInfoA.fMask        := SEE_MASK_NOCLOSEPROCESS;
    ShExecInfoA.lpVerb       := 'open';
    ShExecInfoA.lpFile       := PAnsiChar(AnsiString(Filename));
    ShExecInfoA.lpParameters := PAnsiChar(AnsiString(Params));
    ShExecInfoA.lpDirectory  := PAnsiChar(AnsiString(ExtractFileDir(Filename)));
    ShExecInfoA.nShow        := WindowState;
    Result := ShellExecuteExA(@ShExecInfoA);
  end;
end;

Oder kümmert sich das System selber darum, wenn das Programm dann wirklich mal vom Benutzer geschlossen wird?

Gruss
