Hi As usual i recd. following message on my build output window How to find the point of the memory leak and how to overcome it. Thanks a lot for any suggestion. Sandeep

The second leak should "D:\Documents and Settings\erc\Desktop\Pattern\DBManager.cpp(32) " Double click it and it will take you to where it was allocated. As for the first, you have a leak via a CString somewhere.
