Personally, we should get away from using blobs all together if you are storing a structure in a blob that could easily be broken into a table so you don't bump into limitations of the blob and it will speed up the database blobs are the slowest data type to write to and read from. I have poured over the db structures and as long as all that data is stored in blobs there is no reason to try and optimize any other structures any gains would be small compaired to normailizing out the blobs holding complete structures. I have been working on it a little bit but I just don't know vc++ as a tool very well at all I bought a book but the last IDE I used to build c++ programs was borland 4
Lots has changed since then.
