Can someone help me convert this to
I can't read this whatsoever, i can barely read it XD

I don't know what it does but you need several librarys that I don't think you can use with vb. As far as I can tell it is just a bunch of definations.

yup it does nothing in particular

why do you need to convert it?

Cause as of now, im just doing some learning regarding to decrypting the encrypted logins from firefox locally. Not for malicious use at all ;D

And I can't read c++ that well so i need a base as where i can start off so i'd know what to do in

And yes, it does use several libraries which i can import into the vb project. THen declaring those functions within the libraries and then add varibles and more declarations.

Thanks for the response, so would you mind helping me start from the base and there is also more to the code but i'd think it'll be too much of a hassle for you guys to help me with that >.>

You may not be able to do such thing in C++ , better try to learn java/VC++ .
