serializing data to memory.

Hi,

I have a requirement to save the serialized data in memory. I tried using CMemFile instead of CFile for saving the serialized data in memory. But serialization becomes too slow since the data size is huge. Is there any other way I can save my serialization data in memory instead of a file?
Please let me know if you know any solution.

Thanks.

maybe something like this:

CSharedFile	sf(GMEM_MOVEABLE|GMEM_DDESHARE|GMEM_ZEROINIT);
CArchive	ar(&sf, CArchive::store);
obj->Serialize(ar);
ar.Close();

?

Hi Chris,

Thanks for your reply. I tried this also. But the problem is I'm using 50 MB data to store in memory. So these classes dont help since it stores data in RAM and it affects the performance. So the serialization is slow. It takes 20 minutes to serialize the 50 MB data. So I need to store the serialized data in hard disk(not in RAM) but not as a file. Is there a way? Please help me if you know.

Thanks for your help.

class structure

hello guys

is there a way in c++ to analyze a class structure??
i.e: getting the private and public data and functions in the class without having the source code of the class; only the binary !! maybe using the RTTI

Binary data for a class ?? What do you mean ? It is saved in a file and you want to 'reverse-engineer' the file ? Then I think this will be a little bit difficult because it depends a lot of the guy who wrote the class.

Re: class structure

Amr Shahin10-May-06 2:44

10-May-06 2:44

well ya; i meant that only the object code of the class is available; just like the CString class for example.

i dont want to reverse engineer the class, i just want to get its structure, i can get the public interface through the documentation of course, but i wanna know if there is a way to know what are the private stuff in the class, not the implementation, only the type of variables, and segnature in case of functions

Re: class structure

Cedric Moonen10-May-06 2:50

But...

Fot the CString class you can see the members of the class if you want to. If you have the header file (which is needed to be able to use the class), then you have all the members of the class. Just right click on the class name and select go to definition.

man!
i said CString as an example of a class that u dont have its source code; and the RC->go to defenition gives only the public stuff!
