still digging... for broker.tlb (dll) to be usable for all visual
studio programming languages, it seems it needs to be provided as
a "shared assembly". A shared assembly needs "Strong names" - that
is, the dll needs to be signed with a public/private key. This can
be done once in Visual Studio 2005, by
1. generating a key with the "sn" utility
2. signing the broker project using the signing tab in project
properties(only Tomasz would be able to do this)
3. once recompiled, the (signed) assembly can now be made universaly
available through the global assembly cache by copy to
windows\assembly (XP)
OR - am I digging in the wrong direction - and there is a much
simpler solution to use the amibroker object model in C#/Visual
Studio with late binding that just escapes me?
