You should use the CTime::GetTime() method.

requestData->asOfDate = m_TxnDate.GetTime();

Thanks Nonubik

I modified a little bit as I was getting the following error :

error C2440: '=' : cannot convert from '__time64_t' to 'time_t *'

so I tried requestData->asOfDate = (time_t *) m_TxnDate.GetTime();
and the compilation was successfull.  Thanks again!

Can you tell me something about __time64_t and time_t as to how to use them or what they are?

 

by: nonubikPosted on 2009-01-30 at 07:46:35ID: 23509401

If your member asOfDate is a pointer to time_t, then you should:

*(requestData->asOfDate) = m_TxnDate.GetTime();

If you checkout the header time.h you'll see that time_t is defined as follows:

#ifndef _TIME_T_DEFINED
#ifdef _USE_32BIT_TIME_T
typedef __time32_t time_t;      /* time value */
#else
typedef __time64_t time_t;      /* time value */
#endif
#define _TIME_T_DEFINED         /* avoid multiple def's of time_t */
#endif
