How to use put_DateTime

[Matthew Jew]

Hello,

I cannot figure out what to call instead of "get_Value" so that I can  
use "put_DateTime" on my "loginDateTime" field.

	I_Field_Ptr		loginDateTime;

	aAuthLogTable.loginDateTime->get_Value(forAdd)->put_DateTime 
( aDateTimeRec->year, aDateTimeRec->month, aDateTimeRec->day,  
aDateTimeRec->hour, aDateTimeRec->minute, aDateTimeRec->second, 0 );

Should this field be declared as an "I_Field_Ptr" or as something else?
How do I make the call to "put_DateTime" work?
