Well VB6 can be extended :-)

There is on VBLOB.FromFile/ToFile but not on read/Write raw data, as of what
I have found anyway.
Would be noice if you could fix one for next beta/release

I thought of avoid this. I know that in VB you can put a var to a file as
binary and read it back getting it correct but it would erase the point with
my idea :-)

Well I will go for my old format for now, but if you could check up on how
BLOB is implemented in VCOM and do an example with Read/WriteData it would
be great. I have DLL with many functions to deal with binary data in VB,
just don't know which to use as I don't know how the stoarage format is
composed.
