i am a software developer in Visual basic 6.0. i want to know that may i need any licencee from microsoft to develop any application in vb 6. if yes, please let me inform that from where i can can purchase this paper licence, because microsoft has already stopped the services from vb 6.
VB 6.0 is long dead so I doubt that Microsoft would care what you developed with it. You should also be aware that no business is likely to want to buy applications developed in such an old and unsupported language.
I've working alone in my web business for quite long, and I'm willing to start a bigger project that will need to involve more coders.
I hire frelancer from time to time, but I will need now more than one coder and designer working together in the same project. What could be the better way to manage this team of remote workers? is there any web solutions to manage that? How can I do it knowing that they will not steal the project?
Check out CloudForge. It supports both svn and git for scm. The basic version is free and allows unlimited users and private repos. The paid version has access control and permissions. It sounds like that is what you are looking for? It also has an Agile tracker and other tools for project management. Hope this helps.
how, and what python can help me setup a business?
It is most unlikely that Python can help you set up a business. Starting in business you first need to find an idea that you can market and people will pay for. It could be a manufactured product, food that is grown, or some type of service, but you need the idea and a business plan first.
