Thanks for that example. A few questions. Is it a 64-bit COM server?
Did you create that manifest manually or with a tool that generates it?
Is there a free such tool? By any chance, do you know whether the
syntax would be different for a COM server built with .NET? Lastly, is
it possible to point the CreateObject function to a type library file
(.tlb) associated with the COM server rather than an XML manifest file?
