Store some variables in disk

[AlanCCC]

Hi,

I am using Visual C++ to write an app. One problem is that the application will allocate a lot of object instances of a specific class CMyObject, maybe 400, 000. This will cause “Out of memory” error when total allocated CMyObject reaches 400,000.

To solve this problem, I just wonder when a new CMyObject instance is created, is it possible to specify so that the instance will allocate on a disk cache, or file mapping instead of the memory space?

Thanks

Alan

Most probably the need in allocating a half million objects indicates bad design issue.

What igor said.

Regardless of bad design issues
If you are exhausting the address space of your application (for a Win32 app this is 2Gb, possibly 3gb with a switch in the build settings and depending on which version of windows) then you will need to do any disk based management yourself.

Compiling as a Win64 app might work, though it's still probably bad design to have that many objects.

Hard to say without knowing what you're doing, but perhaps you need a database.
