The Shell Object is documented in the MSDN library - I've posted a FAQ with the relevant pointers to the .CHM files, although IEXPLORE.CHM has now been combined into a more comprehensive and larger file, INET.CHM, in the Kanuary release of the MSDN Library. If your other VFP application is a COM server, you do not need the intervention of the Shell object to talk to the COM component - instantiate it and talk to it's COM interface.

If you're looking to launch another instance of VFP, you can do so via RUN orby using my API_APPRUN, which has the advantage of giving you a process handle to the launched application. If you want to access methods in another VFP session, then instance a VFP application as an out-of-process server (you can CREATEOBJ() or GETOBJECT() as appropriate.)
