I should say at the outset that I am not an expert on C++. All of my Mapinfo COM
experience is from Visual FoxPro.
However, you should be able to use something like createobject("Mapinfo.Application")
to start Mapinfo as a COM object (depends on your flavour of C++ i.e. createobject
returns the object. You can then use this object to execute MapBasic commands with DO
e.g. if your object is called mm then mm.do('Print "Hi"') will execute Mapbasic's
print command. mm.visible=true will bring up the Mapinfo application window. The
problem I have found with all this is that createobject always starts a new instance
of the application. It would be really useful to simply connect to the current
instance - so I'm unable to help with the second part of your question.
