Abstract

A method and system are provided for updating software on a handheld computer in communication with a client computer system operable to connect to a network. Software installed on the handheld computer is identified with the client computer. Moreover, information on the identified software is transmitted from the client computer to a server connected to the network. Further, updated versions of the software installed on the handheld computer are transferred from the server to the client computer based on the identified software that is installed on the handheld computer. Still yet, the software installed on the handheld computer is updated with the updated versions transferred to the client computer.

Claims

1. A method comprising:

identifying software installed on a handheld computer with a client computer and transmitting information on the identified software from the client computer to a server connected to a network, the information including a list of software and version identifiers;

updating the identified software installed on the handheld computer with the updated versions transferred to the client computer;

wherein the list of software and version identifiers included in the information on the software identified as installed on the handheld computer are temporarily stored in a database on the client computer;

wherein if the handheld computer is disconnected from the client computer, the updated versions of the identified software installed on the handheld computer are transferred from the server to the client computer and the identified software installed on the handheld computer is updated a next time the handheld computer is in communication with the client computer.

2. The method of claim 1 further comprising initiating communication between the handheld computer and the client computer.

3. The method of claim 2 wherein the initiating communication comprises connecting a serial line between the handheld computer and the client computer.

4. The method of claim 3 wherein the connecting a serial line comprises placing the handheld computer in a cradle connected to the serial line.

5. The method of claim 1 wherein the network is the Internet.

6. The method of claim 1 wherein the network is a local area network.

7. The method of claim 1 further comprising notifying a user of the handheld computer that the installed software has been updated.

8. The method of claim 1 further comprising scanning data on the handheld computer for viruses.

9. The method of claim 1, wherein the updated versions of the identified software are transferred from a plurality of servers.

10. The method of claim 1, wherein the list of software and version identifiers are identified utilizing a file transfer manager of the client computer which is in communication with an update conduit of the client computer.

11. The method of claim 1, wherein the database on the client computer is connected to an update conduit of the client computer.

12. The method of claim 1, wherein if the handheld computer is disconnected from the client computer, the updated versions of the identified software installed on the handheld computer are stored in the database on the client computer until the next time the handheld computer is in communication with the client computer.

13. The method of claim 1, further comprising clearing data record status flags in the database after the identified software installed on the handheld computer is updated with the updated versions transferred to the client computer.

14. The method of claim 1, wherein the database includes a database header and record information.

15. A computer product embodied on a tangible computer readable storage medium comprising:

computer code that reads data from a handheld computer to identify software installed on the handheld computer;

computer code that transmits information on the identified software from a client computer to a server connected to a network, the information including a list of software and version identifiers;

computer code that while synchronizing data between the handheld computer and the client computer, transfers updated versions of the identified software installed on the handheld computer from the server to the client computer based on the information on the identified software that is installed on the handheld computer;

computer code that updates the identified software installed on the handheld computer with the updated versions transferred to the client computer; and

a computer readable medium that stores said computer codes;

wherein the computer program product is operable such that the list of software and version identifiers included in the information on the software identified as installed on the handheld computer are temporarily stored in a database on the client computer;

wherein the computer program product is operable such that if the handheld computer is disconnected from the client computer, the updated versions of the identified software installed on the handheld computer are transferred from the server to the client computer and the identified software installed on the handheld computer is updated a next time the handheld computer is in communication with the client computer.

16. The computer product of claim 15 further comprising computer code that initiates communication between the handheld computer and the client computer.

17. The computer product of claim 16 wherein the initiating communication comprises connecting a serial line between the handheld computer and the client computer.

18. The computer product of claim 17 wherein the connecting a serial line comprises placing the handheld computer in a cradle connected to the serial line.

19. The computer product of claim 15 wherein the network is the Internet.

20. The computer product of claim 15 wherein the network is a local area network.

21. The computer product of claim 15 further comprising computer code that notifies a user of the handheld computer that the installed software has been updated.

22. The computer product of claim 15 further comprising computer code that scans data on the handheld computer for viruses.

23. A system including a tangible computer readable storage medium comprising:

logic that reads data from a handheld computer to identify software installed on the handheld computer;

logic that transmits information on the identified software from a client computer to a server connected to a network, the information including a list of software and version identifiers;
