Abstract

A system for posting and downloading messages and files from a bulletin board system is described. The system allows a user to retrieve a message from a bulletin board system and then selectively download files which are represented within the message as objects, which may be visually presented to a user as icons.

Claims

1. In a computer network comprising a first client computer, a second client computer, and a publicly accessible bulletin board server, a method for posting a message and a file to and downloading the file from the bulletin board server, the method comprising the steps of:

creating in the first client computer the message to be posted and inserting a file object representative of the file in the message;

requesting the first computer to post the message to the bulletin board server, and in response, the first client computer recognizing the file object inserted in the message and the first client computer posting the first message to the bulletin board server and automatically uploading the file to the bulletin board server;

displaying the message and a representation of the file object on a display of the second client computer; and

downloading the file from the bulletin board server to the second client computer.

2. The method of claim 1 wherein the downloading step comprises the steps of:

viewing file information stored in the file object; and

selectively transferring the file from the bulletin board server to the second client computer based on the file information.

3. The method of claim 1, wherein the bulletin board server comprises a plurality of networked computers.

4. The method of claim 3, wherein the posting step includes the steps of:

transmitting the message and the file in a single information stream; and

storing the message and the file on different computers within the plurality of networked computers.

5. The method of claim 1, further comprising the step of automatically compressing the file in response to inserting the file object in the message.

6. The method of claim 1, further comprising the step of automatically decompressing the file in response to the downloading step after the file is stored on the second client computer.

7. The method of claim 1, wherein the message comprises a rich text format.

8. The method of claim 1, wherein the message is part of a message thread.

9. The method of claim 1, wherein the representation of the file object is an icon, and a third client computer input in the downloading step includes selecting the icon;

and the downloading step further includes displaying object information relating to the file in response to the selecting of the icon on a display of the third client computer.

10. The method of claim 9, wherein the selecting of the icon comprises the steps of:

positioning a pointer on the icon; and

actuating an input device.

11. The method of claim 9, wherein the object information includes the size of the file.

12. The method of claim 1, wherein the file object is an object-oriented object.

13. The method of claim 12, wherein the file object includes a data structure and routines to perform operations on a value stored the data structure.

14. The method of claim 12, wherein the file object is a Microsoft On-Line System Attach File (MOSAF) object.

15. The method of claim 1, wherein the file object includes a plurality of attributes, at least one of the plurality of attributes relating to the contents of the file.

16. The method of claim 15, wherein the file object contains an attribute describing the compression method used to compress the file.

17. The method of claim 16, further comprising the step of automatically decompressing the file in response to the downloading step after the file is stored on the second client computer if one of the attributes included in the file object indicates the file was previously compressed.

18. The method of claim 15, wherein the file object contains an attribute describing the size of the file.

19. The method of claim 15, wherein the plurality of attributes include a file ID, and the downloading step includes the steps of:

retrieving the file ID from the file object;

sending the file ID to the bulletin board server;

accessing the file with the file ID on the bulletin board server; and

sending the file from the bulletin board server to the second client computer.

20. The method of claim 1, further comprising the steps of:

evaluating the file, in response to inserting the file object in the message, to determine whether the file has or has not been previously compressed; and

automatically compressing the file in response to the evaluating step determining the file has not been previously compressed.

21. The method of claim 1, wherein a third client computer input in the downloading of the file includes manipulation of the representation of the file object.

22. A computer-readable medium having computer-executable instructions for performing the steps recited in claim 1.

23. In a computer network comprising a first client computer, a second client computer, and a publicly accessible bulletin board server, a method for posting a message and a file to and downloading the file from the bulletin board server, the method comprising the steps of:

creating in the first client computer the message to be posted and inserting an object-oriented file object representative of the file in the message, the file object having been instantiated from an object class;

requesting the first computer to post the message and the file to the bulletin board server, and in response, the first client computer recognizing the object-oriented file object inserted in the message and the first client computer posting the first message to the bulletin board server and automatically uploading the file to the bulletin board server;

displaying the message and a representation of the object-oriented file object on a display of the second client computer; and

downloading the file from the bulletin board server to the second client computer in response to manipulation of the representation of the object-oriented file object.

24. The method of claim 23, wherein the bulletin board server comprises a plurality of networked computers, and the message and the file are stored on different computers within the plurality of networked computers.

25. The method of claim 23, further comprising the step of automatically compressing the file in response to inserting the object-oriented file object in the message.

26. The method of claim 23, further comprising the step of automatically decompressing the file in response to the downloading step after the file is stored on the second client computer.

27. The method of claim 23, wherein the message comprises a rich text format.

28. The method of claim 23, wherein the message is part of a thread.

29. The method of claim 23, wherein the file object includes a data structure and routines to perform operations on a value stored the data structure.

30. The method of claim 23, wherein the file is automatically uploaded, using the object-oriented file object inserted in the message, to the bulletin board server in response to the posting of the message.

31. The method of claim 23, wherein the object-oriented file object contains a plurality of attributes, at least one of the plurality of attributes relating to the contents of the file.

32. A computer-readable medium having computer-executable instructions for performing the steps recited in claim 23.
