Параметры

pFormat
A formatting string similar to the printf formatting string. Formatting codes, preceded by a percent (%) sign, are replaced by the corresponding COleDateTimeSpan component. Other characters in the formatting string are copied unchanged to the returned string. The value and meaning of the formatting codes for Format are listed below:
- %H Hours in the current day
- %M Minutes in the current hour
- %S Seconds in the current minute
- %% Percent sign
The four format codes listed above are the only codes that Format will accept.
nID
The resource ID for the format-control string.

Возвращаемое значение

Пример

// get the current time
COleDateTime tmStart = COleDateTime::GetCurrentTime();

// waste some time
CString str;
::Sleep(3000);

// get the current time again
COleDateTime tmFinish = COleDateTime::GetCurrentTime();

// find the difference
COleDateTimeSpan tmSpan = tmFinish - tmStart;

// tell the user
str = tmSpan.Format(_T("%S seconds elapsed"));
_tprintf_s(_T("%s\n"), (LPCTSTR) str);
