>Hi,
>Thank you for reply. What do u mean by coding exclusively in VFP??

Using Visual FoxPro to write all applications that reference the mid-tier; a VCX is FoxPro code, so you can't have a VB app look at a VFP .VCX and use it directly. You have to compile the code in the VCX to an in-process or out-of-process COM server, and then have another language use the COM server's OLE interface to access the class.

A VFP application can execute native VFP code directly, so there's no need to compile a separate COM server and use an OLE interface; if you include the VCX in a project, a VFP app can instantiate a VFP class directly and talk to it using the native VFP interface.
