Abstract

A method and electronic system for exchanging data between a handheld device and another computer system are described. A data file is transferred to the handheld device using the install application of a synchronization manager. The transferred file is stored as a digital stream file with its native data encoding. After synchronization, a message is sent to notify the exchange manager about the data file. The exchange manager then uses an application registry to identify the application program that corresponds to the file stream based on the extension of the stream file. The pertinent application program is then invoked and the stream file is dispatched to the application for processing. During processing, the pertinent application then formats the stream file such that the data file becomes a record within the database file that is associated with the pertinent application.

Claims

1. A method of transferring data to a handheld device comprising the steps of:

a) using a universal conduit to transfer data to said handheld device, said data containing an indication of a file type;

b) storing said data as a stream within said handheld device and associating said file type with said stream;

c) indexing a registry with said file type of said stream to determine an identified application of said handheld that corresponds to said file type;

d) an exchange manager reading said stream and dispatching said stream to said identified application; and

e) said identified application processing said stream in accordance with other objects associated with said identified application.
