Best Practices for Error Handling -
Speaker: Rick Schummer
Error handling is an integral part of any application because all applications have natural and unnatural error conditions triggered as the users exercise the software. Visual Fox Pro has several techniques available to address these errors. Which is better to use? Should you implement an all encompassing, monolithic global error handler? Is the encapsulated Error method the route to go? Should you invest the time to modernize the architecture using the structured error handling introduced in VFP 8? Is a blend of the various options the best practice you should adopt? How are you going to be informed when the applications you support donít work as advertised?
This session will provide several best practice ideas to address the following issues:
1.Addressing the errors in your applications.
2.Errors can be different depending on the type of application (tradition desktop, client/server, Web).
3.Demonstrating all the error handling techniques available in Visual Fox Pro and discuss when you might use one over the other or integrate some together.
4.Determining the information you can trap so you know what went wrong, and where the user was when the trouble occurred.
5.Capturing the details and key information surrounding the error.
6.Communicating errors back to the development team so the problem can be fixed if necessary.
7.Tracking errors once they are reported.
