Question: I cannot work out the difference between HasUncommittedChanges and Modified for the Dataset.

 Answer: HasUncommittedChanges is set to True in case the dataset got changes which were not commited. If you use AutoCommit, HasUncommittedChanges will be always False. Then all record modifications will be commited.

Our 911 dispatch center needed a program to monitor the status of equipment used in emergency situations. If one dispatcher modified the status of a piece of equipment, all the other dispatchers needed to see this change immediately. The most elegant way to implement this was by using Firebird Events to asynchronously notify all the users whenever a pertinent change had occurred at the database server. After failing to implement this myself using the Firebird API, I bought a copy of FIBPlus. I dropped a Database, EventAlert and ErrorHandler control into a C++ Builder DataModule and within minutes I had all the functionality I needed. I was able to complete the project quickly and the users are thrilled with the results because I gave them more features than they originally asked for. >>
