I was Starting Windows application Developing in 2002, I was Using Access And Vb.6.0 in that years . Poco a poco we change our tools to SQL Server and vb.net but today I Use WPF and c# Instead of VB.net . I Spend 2 Years on an ERP - A program that Cover Every Customer Need in Just One Integrated application - for Electricity Distribution Company of The local Province. So I Prefer A large Menu of Tools and Technologies and so many years of Experience.
