> As a system programmer who used VB6 as a glue or ochestrator (early 2000s) of low level components I say the only important flaw I found was on its single threading model. As a developer cutting my professional teeth in the late 90's / early 2000's, VB was amazing for building utilities and other bits of software run by individuals on their machines. When we tried to reuse components built for those applications in our web applications, issues with the threading (single threaded apartment) model soon became apparent, so we rewrote those in C++ in order to support the level of concurrency we needed.
