怎样将TDateTime型变量转化为秒数？
例如：
00:01:02转为秒数为62

[傻乐tao]

TDateTime dt;
long total,h,m,s;
AnsiString temp;
dt=Now();
temp = TimeToStr(dt);
ShowMessage(temp.Length());
if(temp.Length() == 8)
{
h = temp.SubString(1,2).ToInt();
m = temp.SubString(4,2).ToInt();
s = temp.SubString(7,2).ToInt();
}
else
{
h = temp.SubString(1,1).ToInt();
m = temp.SubString(3,2).ToInt();
s = temp.SubString(6,2).ToInt();
}

total = h*3600 + m*60 +s;

//total -> the seconds

先用FormatDateTime()把TDateTime类型的变量转换成你方便处理的字符串，然后对String作处理，不用多说了吧！

[MountLion]

long vSec;
TDateTime vTime;
...
unsigned short hour,min,sec,msec;
vTime.DecodeTime( &hour, &min, &sec, &msec);
vSec=sec+((long)min*60+hour)*60;

[MountLion]

short hour,min,sec,msec;
vTime.DecodeTime(&hour,&min,&sec,&msec);
vSec=msec+((long)min*60+hour)*60;

最简单的方法：
TDateTime t;
int n;

n= (double)(t) * 86400;

同意windindance(风之舞)，这最好

我觉得时间本身就是浮点型的,你设定断点看看中间值
