OCX components

The SDK comes with some ocx components. I was able to read and write data within the SAP system from an external non SAP program with these ocx components. I am familiar with the site http://www.bapi.is-here.de/ but that is just from external application to SAP system.

I would like to know if it is possible to read/write data from/to an external non SAP program with these ocx components? and if so how?
