Question

c++builder中，我用edit1、edit2、edit3分别表示年月日，怎么返回到datetimepicker中？

就是比如我在edit中输入20130513，在datetimepicker中显示2013/05/13

Answer 1

给你个例子 详见 附件

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    WORD year = StrToInt(Edit1->Text);
    WORD month = StrToInt(Edit2->Text);
    WORD day = StrToInt(Edit3->Text);
    DateTimePicker1->Date = EncodeDate(year, month, day);
}

Answer 2

Cstring time;
Time.format("%s/%s/%s",year,month,day);
