Add-in Express is not the holy grail, but is as close to it as a programming suite can be

All our problems have been solved since we started to use Add-in Express! It provides us with an excellent framework doing all nasty work in the background. No more trouble with ActiveX interfaces, no more hours of debugging to find the source of some silly bugs, no more late work due to unsolved problems.
