How hard is this?

I have to write a DLL in C which opens a file and does bit
manipulations with the raw data... ie. take each character
of raw data and perform character to binary, do the manipulations on the binary number then convert it back to
a character and save this new file.

I have extensive knowledge in vb and fundamental knowledge
in C.

I need to reference this DLL from a vb project.

How hard does this sound?

Thanks for the help.

It's not so hard once you get the structure. I can email you an example of making a DLL, if you want.

that would be great
my main emphasis is on making the dll external to my vb project, everything else is generally simple

my email is [email protected]

thanks for the help!

for those others in the dark...

you should build a simple win32 DLL program file.
you must export the functions.

but i think the e-mail did well enough.
