用CreateProcess()，可以用来得到控制台程序的返回字符串，这里是一个和delphi的例子：function ThreadComp.RunTerminal(const Prog, CommandLine,Dir: String;var ExitCode:DWORD): String;
var
  HRead,HWrite:THandle;
  StartInfo:TStartupInfo;
  ProceInfo:TProcessInformation;
  b:Boolean;
  sa:TSecurityAttributes;
  inS:THandleStream;
  sRet:TStrings;
begin
  Result := '';
  FillChar(sa,sizeof(sa),0);
  //ÉèÖÃÔÊÐí¼Ì³Ð£¬·ñÔòÔÚNTºÍ2000ÏÂÎÞ·¨È¡µÃÊä³ö½á¹û
  sa.nLength := sizeof(sa);
  sa.bInheritHandle := True;
  sa.lpSecurityDescriptor := nil;
  b := CreatePipe(HRead,HWrite,@sa,0);
  CheckResult(b);  FillChar(StartInfo,SizeOf(StartInfo),0);
  StartInfo.cb := SizeOf(StartInfo);
  StartInfo.wShowWindow := SW_HIDE;
  //ʹÓÃÖ¸¶¨µÄ¾ä±ú×÷Ϊ±ê×¼ÊäÈëÊä³öµÄÎļþ¾ä±ú,ʹÓÃÖ¸¶¨µÄÏÔʾ·½Ê½
  StartInfo.dwFlags     := STARTF_USESTDHANDLES+STARTF_USESHOWWINDOW;
  StartInfo.hStdError   := HWrite;
  StartInfo.hStdInput   := GetStdHandle(STD_INPUT_HANDLE);//HRead;
  StartInfo.hStdOutput  := HWrite;  b := CreateProcess(PChar(Prog),//lpApplicationName: PChar
         PChar(CommandLine),    //lpCommandLine: PChar
         nil,    //lpProcessAttributes: PSecurityAttributes
         nil,    //lpThreadAttributes: PSecurityAttributes
         True,    //bInheritHandles: BOOL
         CREATE_NEW_CONSOLE,
         nil,         
         PChar(Dir),
         StartInfo,
         ProceInfo    );  CheckResult(b);
  WaitForSingleObject(ProceInfo.hProcess,INFINITE);
  GetExitCodeProcess(ProceInfo.hProcess,ExitCode);  inS := THandleStream.Create(HRead);
  if inS.Size>0 then
  begin
    sRet := TStringList.Create;
    sRet.LoadFromStream(inS);
    Result := sRet.Text;
    sRet.Free;
  end;
  inS.Free;  CloseHandle(HRead);
  CloseHandle(HWrite);
end;

CString str=date.Format("%Y%m%d");
