Are you exporting that class from the DLL so it can be imported
in the app build?

Hi Experts
I am reading a 7GB File line by line and i need to write some of it's contantants into two files of 9MB and 6MB in a function, for reading and writing i am using a while loop,but my application is not writing the complete OUT-PUT Files. it seems my application is not able to read the complete In-Put File.
My System has only 256MB of RAM and hardly 8 GB Free space in my Hard disk.
so can anybody tell me what could be the reason?
Thanks in advance

You are suggesting that he memory map a file... a file that is more than twice his available address space...?
Peace!
N.B. While we do have a 4GB address space on Win32, only 2-3GB of it can be considered available, and even that takes some doing...

Are you storing anything other than the current line? If not, I can't imagine RAM or disk space having any relevancy.
Can you provide a code snippet that exhibits the problem?

I vaguely recall that ifstream doesn't work on files over 2GB. You could try the regular CRT buffered IO calls.

illustrate the contexts. any help?

Hi all,
How to create a C# control (using VC# 2008 .Net) which can be used in any language (mainly in VC++ 2008 .Net)?
Please guide me.
I appreciate any and all comments and suggestions.
Thanks in advance.
