Hi Matt & John Thank you very much for the immediate information. Now I changed my code to comparing date objects instead of memory locations. It is now working fine. But it seems it is a slow process. But still I have one run time problem with the code snippet ---- DateToDOWDMFormat (dateTime.month, dateTime.day, dateTime.year, ShortDateFormat, label);
Even my dateTime.month, dateTime.day, dateTime.year contain valid values like 3, 14, 2002. The error goes like this- App(1.0) just wrote to memory location 0x00000204A which is in memory manager datastructures. These datastrucuters include things like........ Any guess what is going wrong with my DateToDOWDMFormat function. Thankyou once again, With Regards Bhaskar From: Schettino, John (view other messages by this author) Date: Wed, 13 Mar 2002 13:09:05 -------------------------------------------------------------------------------- I think what he was going for was MemMove(): MemMove((VoidPtr) searchRec, (VoidPtr) &searchDate, sizeof(DateTimeType)); Something like that I suppose -----Original Message----- From: Matt Hebley [mailto:[EMAIL PROTECTED]] At 08:49 AM 13/3/2002 -0800, you wrote: > How can I search a database record using date field. >I want to retrieve all records whose date field >matches search date.

It looks to me like you need a DateTimeType struct in your searchRec (or use a DataTimeType as your search object). See docs on TimSecondsToDateTime.
