hello all, we have been using boost serialization library for quite some time in small scale project. so far, we are happy with boost serialization, since it offers several features which are not found in MFC framework. before we migrate boost serialization library is large scale project, can we know 1. is there any limitation on the file size generated by serialization. i.e. what is the maximum file size which can be written by boost serialization? 2. is there any limitation on the object size, which can be loaded/ unloaded by boost serialization? 3. does boost serialization offer any way (checksum?) to ensure the file being written is not corrupted? thank you very much yccheok __________________________________________________ Do You Yahoo!?
