We want to use a DLL written by Chrome that runs on all of the platforms that Xojo does. We are hoping Xojo can call into C++ libraries.
No. C Functions work with Declares, but not C++.
Are you sure a Declare only loads functions from DLLs originally written in C and not C++?
You can only call simple methods. You can not call C++ class constructors or methods directly.
I think that this is how people usually expose their interfaces. So probably it can be done. Mike probably just need some research to verify the behavior. Probably not valid for .Net content, seems they usually expose classes.
