dll interface rewrite

I had someone write a dll for me in VC++, the dll seems to work fine when called from another C++ program that also uses teh .h file for the dll. The problem is that I need the dll to work in VB. So as the dll when run from C++ prog seems to process the data correctly I am assuming that part of it works fine. So I think its the interface to it that needs to be rewritten. Which is what I am requiring. The dll has only three functions to it. I dont know much about C++ so I cant do it. I will send the source code to the person I pick to do the project. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2)A sample VB program that uses the new dll for me to test with. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Windows (ALL) Must work in VB before I accept payment.
