Hi Ashish,
The simplest way would be to instantiate an object which is an Out of process server in VFP. Instantiate it from either application and get a reference to it from VFP and delphi. The object's properties will be accessible by both the applications so delphi as well as VFP will be able to access it.
>How can I access parameter which is passed by Delphi exe. to a VFP exe or how can I pass parameter from VFP to Delphi ?
