Hi Soykan,

VFP application can exchange data with Pocket PC (Windows CE based device) in following ways:

- create, modify and delete files on Pocket PC
- copy files from Pocket PC to computer
- copy files from computer to Pocket PC
- modify System Registry of Pocket PC
- access Pocket PC databases like Contacts or Tasks
- start applications on Pocket PC

On my web site there are several Pocket PC classes implementing this functionality. This part of API is called Remote Application Programming and allows to invoke some Windows CE calls remotely:

Pocket PC: custom RAPI class for operating with files and folders on mobile device

Pocket PC: custom RAPI class for operating with the System Registry

Pocket PC: custom RAPI class for operating with the Object Store Databases

Pocket PC: custom RAPI class for executing routines on remote Windows CE device

You can not use VFP to create application running on Pocket PC.
