The following C++ program will connect to an Oracle Calendar server and retrive an iCal file for a particular user. The program is hard-coded with the Oracle Calendar used at Case. At execution time, the program binds to the Oracle Calendar server as the user defined by the CALENDAR_USER environment variable who has the password set with the CALENDAR_PASSWORD environment variable.

This program requires the Oracle Calendar SDK to compile and run.

If you use this program, please leave a comment.
