Problems storing NULL-date with RFX_DATE-function in vc++4.1

Environment: VC++4.1, Win 95
Problems storing NULL-date with RFX_DATE-function in vc++4.1

I've been using RFX_DATE(taking TIMESTAMP_STRUCT as argument) in an  vc++1.52
- application.
The function uses AFX_RFX_TIMESTAMP_PSEUDO_NULL (99)  to communicate
NULL-values.
The application uses ODBC to access the database.
This works just fine !!

Problems, however, appeared when I converted the application to vc++4.1. Now
it's impossible to store  a NULL-date without getting errormesseges like
"Illegal Time" (SQLServer) or "Date/Time-field overflow" (MSAccess).

Anyone had the same experience? And have a solution?

I'm greatful for any ideas!

I am also using SQL Server/MS Access and storing NULL in date/time fields.

I'm using the CTime class within a CRecordset derived class. I simply set
the variable = 0;

Ex. m_StartDateTime = 0;

This seems to work fine for me.
