Editorial: VFP 9 SP2 News
[[Doug Hennig]]
The perception and adoption of the Visual FoxPro 9 Service Pack 2 has been in a word, underwhelming. Reports of the Report Designer having some bugs and the Help file being a mess spread across the various forums and blogosphere extremely fast. Rick has good news on both fronts!
VFPX: PEM-Editor
[[Rick Schummer]]
The PEM Editor is one of the fastest moving projects on VFPX and for this reason one of the hardest tools to write about in this continuing series. That said, this month Rick attempts to catch you up on all the development for the PEM Editor, show you some of the super cool features it has to help you be more productive, and expose some of the new functionality being developed for the fourth release of this powerful tool.
Deep Dive: Creating Explorer Interfaces in VFP, Part 3
[[Doug Hennig]]
The last article in this three-part series finishes examining a set of classes that provide Explorer-style interfaces to Visual FoxPro applications.
New Ways: Handling Code that Changes at Runtime
[[Tamar Granor, PhD]]
There are lots of places in VFP code where you don’t know until the code is running exactly what you want it to do. Perhaps you want to let the user choose a file to operate on, or you want to run a report based on criteria specified by a user. VFP offers a number of different ways to handle code that isn’t known until run-time. Knowing which one to use when affects the efficiency, accuracy, and reliability of your code, but many people stick with macros and don’t use any of the other options. In this article, I’ll look at each of the options and discuss where it’s appropriate.
Best Practices: Best Practices Part IV
[[Jim Booth]]
Last month we covered the introduction of object orientation and some of the key concepts of that programming paradigm. This month we will continue to look into the key concepts of object orientation and discover some additional mechanisms that are at our disposal within this conceptual programming approach. In addition to covering some more of the programming concepts of object orientation, this month we will introduce and discuss at some length the idea of application frameworks and see how they are constructed and what they can do for us. Obviously, in a single article we will not be building a complete application framework or even discussing a complete framework but we will cover enough about frameworks to give you a very good start on how to approach building your own and how to evaluate any of the many commercial application frameworks that are out there.
Use FastNoData to drastically improve form load times
[[Mike Yearwood]]
Forms that take too long to load are a cause of frequent complaints. Here’s a technique that can dramatically reduce form load times. I’ve seen anywhere from 8 to 4375 times faster. My most complex form went from loading in a range of 8 to 10 seconds, down to a consistent 2.2 seconds.
