时间比较为什么不生效？

#define DEF_OPEN_TIME “9：00：00”
if (pForm3->DateTimePicker2->Time.TimeString() <= DEF_OPEN_TIME)
{
ShowMessage("dd");
}
else
{
ShowMessage("oo");
}
为什么时间框选9点之前，还是显示oo？

[解决办法]

C/C++ code

#define DEF_OPEN_TIME "9:00:00"void __fastcall TForm1::Button4Click(TObject *Sender){  DateTimePicker1->Date = 0;  if (DateTimePicker1->Time <= StrToTime(DEF_OPEN_TIME))  {    ShowMessage("dd");  }  else  {    ShowMessage("oo");  }}
