如何返回TDateTime的下一天和下一个月

[daydayup234]

void __fastcall TForm1::Button1Click(TObject *Sender)
{
TDateTime dt;
dt=Now();
unsigned short AYear,AMonth,ADay,AHour,AMinute,ASecond,AMilliSecond;
DecodeDateTime(dt,AYear,AMonth,ADay,AHour,AMinute,ASecond,AMilliSecond);//#include <DateUtils.hpp>


AMonth%=11;
AMonth%=30; //这个要修改
ShowMessage(AMonth);
ShowMessage(ADay);
}

关注!

略微做些修改。

void __fastcall TForm1::Button1Click(TObject *Sender)
{
TDateTime dt;
dt=Now();

TDateTime nextDay=dt+1;
//这样就可以得到下一天了。然后用下面的DecodeDateTime方法就可以得到下一天是几号。

unsigned short AYear,AMonth,ADay,AHour,AMinute,ASecond,AMilliSecond;
DecodeDateTime(dt,AYear,AMonth,ADay,AHour,AMinute,ASecond,AMilliSecond);//#include <DateUtils.hpp>


AMonth%=11;
AMonth%=30; //这个要修改
ShowMessage(AMonth);
ShowMessage(ADay);
}

TDateTime dt=Now();
TDateTime dt1=IncDay(dt,1); //下一天
TDateTime dt2=IncMonth(dt,1); //下一月

IncDay

学习，楼上的TDateTime nextDay=dt+1;似乎不行吧？

[ljianq]

TDateTime dt=Now();

IncDay(dt,1).FormatString("d"); //下一天
IncMonth(dt,1).FormatString("M"); //下一月

[jaffy]

TDateTime dt=Now();
TDateTime dt1=IncDay(dt,1); //下一天
TDateTime dt2=IncMonth(dt,1); //下一月

Sorry, 应该是dt=dt+1即可。
