I'm working with a c++ project that has a lot of COM functions. The majority of the inputs and outputs are VARIANTs. Is there an easy way to serialize/开发者_StackOverflowdeserialize these into long, string, etc using Boost?

Boost has absolutely nothing with regards to Microsoft's COM technology. The closest thing to COM's variant in Boost would be boost::any. You can write COM's variant_t to boost::any converter, then you can serialize, cast etc.

There is an open source OPC (OLE for Process Control) server implementation called FatRat library. It uses boost and pushes a lot of VARIANTs around. Very inspirational.
