Edit State With A Manually Created Navigator?

I have a form to edit data, with a manually created navigator.Everything works, including the record movement, saving and cancelling changes, etc.My question is...how can I detect if there have been changes to the current record prior to moving to a different one?If the user has made changes to the current record and tries to move to a different record without saving them, I want to prompt him to save.All of the events I've found don't detect a changed record until AFTER the change record has occurred.I assume that typing something in any of the text boxes has to implicitly call the beginedit method.Does that not set a flag or generate an event I can use to set my own flag?

I've looked around here and seen stuff about capturing key down events, looping through the text boxes, etc.Is something this normal really that difficult?If I wanted to write 50 lines of code to do stuff I'd be using C instead of VB.I'm switching from Delphi to VB because Delphi costs $2500.But if I have to spend 5 times as long trying to do standard stuff like this...maybe I need to rethink that choice.
