My application access network database files, from time to time, it appears an error message "Insufficient Memory for this operation". Why would this happen?? Is this because I open some query or table without closing it etc?? How to prevent it and solve it??? Thank you.

Is it a TDataSet::Open call ? Why don't you enclose all your TDataSet::Open calls in try-catch blocks ? Are you using the new operator in a loop ? Did you delete your used objects, those you won't need any more ? Jayme. "danny" <danny (AT) teleeye (DOT) com> wrote Quote: Hello...

I finally discovered that some TQuery objects haven't been deleted, so causing such leakage. However, I faced another problem again!! The software from time to time will prompt error: "Insufficient disk space" in query operation. Why would this appen?? Is this again of because I open some query or table without closing it etc?? How to prevent it and solve it??? Thanks. Danny "Jayme Jeffman Filho" <jjeffman (AT) cpovo (DOT) net> wrote Hello Danny, Did check what program line rises this exception ?

BDE sometimes swap queries or table fetches to disk. Be sure you have enough disk space and network rights in the directory the BDE is trying to save temporary files. HTH Jayme.

The PrivateDir is set to a directory created under my application directory (C:ProjectDatabase). And the free disk space of my harddrive is greater than 3G !!!!!! Do you have any idea?? Is it a bug of BDE?? Thank you Danny "Jayme Jeffman Filho" <jjeffman (AT) cpovo (DOT) net> wrote Hello Danny, Have a look at TSession::PrivateDir. BDE sometimes swap queries or table fetches to disk.

I have no more suggestions in this matter. I've never had such exception ! Why don't catch the exception and check what runtime conditions are driving the application to the exception ? HTH Jayme.
