Answer 3

function RunProcessAndWait(const sCmdLine, sRunningDir: string; wShowWindow: WORD): Boolean;
var
  nRetWait: Integer;
  stInfo: STARTUPINFO;
  prInfo: PROCESS_INFORMATION;
begin
  ZeroMemory(@stInfo, SizeOf(stInfo));
  stInfo.cb := SizeOf(stInfo);
  stInfo.dwFlags := STARTF_USESHOWWINDOW;
  stInfo.wShowWindow := wShowWindow;  Result := CreateProcess(nil,
                           PChar(sCmdLine),
                           nil,
                           nil,
                           TRUE,
                           CREATE_NEW_CONSOLE
                           or NORMAL_PRIORITY_CLASS,
                           nil,
                           PChar(sRunningDir),
                           stInfo,
                           prInfo);  if Result then
  begin
    nRetWait :=  WaitForSingleObject(prInfo.hProcess, INFINITE);
    CloseHandle(prInfo.hThread);
    CloseHandle(prInfo.hProcess);
    Result := not (nRetWait = WAIT_TIMEOUT);
  end;
end;

Answer 4

就象hellion(恶人)的代码这样　
关健就是这句WaitForSingleObject(prInfo.hProcess, INFINITE);让它一直处于发信号状态,
至于细节方面,你还是自己看书,看帮助吧,网上讲不清楚
