have any open source software for create vb program

It is like asking: I want to cook a meat dish, without meat.
BTW VB6 is also MS.

The Expess version of Visual Studio is also free.

Hi,

I'd recommend using the express versions as well, - In the full version I can do all my programming for desktop and web sites and I use this as work as the company pay for it. At home, I have Visual Studio Express for Windows Desktop and Visual Studio Express for Web etc all for free Visual Studio 2013 Express for the latest 2013 versions
