":28:2" is not valid date and time

[Comer]

datetime类型变量赋值错误

[hujiangyongxx]

应该怎么改？

[Comer]

这么长？
够看一会了

[Comer]

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

[Comer]

楼主怎么没反应了？

问题解决了没有呢？

[hujiangyongxx]

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

[yeeyee]

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);
