Learn, Network, Be Inspired
Rick has attended developer conferences since 1992 and feels they are an essential part of career development. He credits the countless hours spent sitting in sessions, hanging out in the bar or the pool talking shop, skipping formal sessions to take part in on-the-fl y sessions in the hallways, networking at meals, attending late night bonus sessions, long days, and listening to vendors pitch their products as a critical component to his success as a developer and business owner.
Put Access methods to Work
Tamar E Granor
Access and Assign methods give you a chance to intervene when a property is referenced or changed. Access methods are particularly useful for just-in time calculations.
In my last two articles, I demonstrated BindEvent(), the VFP function that lets you set up a method to respond when an event fires. In this article and the next, I'll take a look at Access and Assign methods, another VFP approach to provide automatic behavior.
Creating ActiveX Controls for VFP using.NET, Part 2
Last issue, Doug showed how to create ActiveX controls from .Net components so we can take advantage of these controls without having to convert our applications to .Net. This month, he continues the discussion to show how to handle events.
VFPX: VFP 9 SP2 Help File
Microsoft released two different Help files for VFP 9 Service Pack 2 (SP2) and both were flawed and considered unusable. I am not sure exactly what happened or how it transpired, but the cold hard fact is no one checked the final Help file Microsoft released during an update of VFP 9 SP2. Fortunately several people in the Fox Community took it upon themselves to attempt to fix it, but only Francis Faure was able to reassemble all the missing pieces and put it all together again. Microsoft Legal gave the final blessing and released it to the Fox Community on VFPX using a Creative Commons license.
SQLite Connection: Inserting Large Amounts of Data into SQLite
“We need to get away from DBFs” is a refrain I hear regularly from fellow developers. Be it due to perceived instability of the file format, the need for tables larger than 2 GB, or the result of political machinations, the result is the same – a desire to move to a SQL database back-end. SQLite can be an excellent intermediate step – and possibly the final word - in the process of restructuring your application to talk to a SQL back-end. In this article, I'll show you how to work with SQLite directly in order to quickly insert large amounts of data into a SQLite database, and then how to export data from SQLite into other data file formats.
Creating Dependency Properties and Understanding DP-concepts
Anyone who has done some Silverlight or WPF has stumbled over the term “Dependency Property” and if he has done some research on it, he has probably found out that nearly all properties of visual objects shaped through XAML code are Dependency Properties, and that for them to work the containing object (such as UserControl or Window) must inherit from DependencyObject. He also might have discovered that this is the mechanism used to allow properties to depend on (or be determined by) the typical XAML-like mechanisms like styles, animations and Xaml-Bindings.
