I can read in fields of all types (CString, int, etc) in a database, but I cannot get the dates (AppWiz defined the date as CTime in the CRecordset derived class) to work properly.  Anyone have any suggestions please??  BTW, I'm using Access 97 and Visual C++ 6.0

Just guessing ... Try changing the type to COleDateTime ( i think Access uses the OLE DATE
type, which must be mapped to COleDateTime instead of CTime, but i am not sure).

You're right snoegler!  COleDateTime is almost the only way to use dates with Access.  Here's a code snipplet that set's the time in my dao table to the current time.

pSearchJobsSet->Edit( );
pSearchJobsSet->m_Start_Time = COleDateTime::GetCurrentTime( );
pSearchJobsSet->Update( );

The opposite *should* be absolutely true.  Here's a pseudo-code to read the same date...

COleDateTime dtStartTime;
dtStartTime = pSearchJobsSet->m_Start_Time;

It's O.K. to use CTime. I have used it with CRecordsets.
CTime gives problems (usually invalid memory reference) when the object is not initialized and the database defaults to one (say to Now()). Try initializing your CTime object to either 0 or CTime::GetCurrentTime(). Basically, initialize it to some value !
