Yes I know that bit, and that is what I did for my old VB6 and Delphi 5 projects. The question here was not only about a "single instance" application, but also how to pass information to the first instance (eg: please open this new file in a tab) before the second instance terminates. Using SimpleIPC should do the trick nicely.
