Answer 3

uses login, dateattribute, share;
这么多单元的引用，你还是自己设置断点问题出在哪吧，把关键代码贴出来就好了

Answer 4

qs:=copy(datetimetostr(dateattribute_w.DateTimePicker2.Date),1,10);
zz:=copy(datetimetostr(dateattribute_w.DateTimePicker3.Date),1,10);
有没有错误啊？

Answer 5

何必呢
function FormatDateTime(const Format: string; DateTime: TDateTime): string; overload;
function FormatDateTime(const Format: string; DateTime: TDateTime; const FormatSettings: TFormatSettings): string; overload;st:=FormatDateTime('yyyy-mm-dd',now);
