Log-based Replication

You have implemented After Imaging haven't you? If your answer is "no" then the next question has to be "Why do you care so little about your data?" Implementing After Imaging is a snap. It's even easier if you're running OpenEdge 10.1x and later.

After the implementation, you can copy the images to a secondary (and even tertiary) machine and roll them forward there. All you need is a plan and a set of scripts and that's what we have here. The article is also on the White Star Software Blog page.

Dynamic Coding

A very useful primer dynamic buffers, queries, and browsers - and how to use them.

Dynamic Temp Tables

What they are, what they're for, how to use them. Dynamic temp tables are a great addition to the OpenEdge toolset. Learn how to use them to separate interface and database interactions.

High Octane Coding

How to write high-performance reports, and how to build new report paradigms. Includes queries, indexing rules, and other insights.

Locks and Scoping

Both a review of standard, procedural rules and a description of issues which involved in the event-driven paradigm which might not be self-evident. Particularly useful if you are writing new, event-driven modules.

XML

Learn about the two XML models of Progress: the document object model (DOM) and the simple API for XML (or SAX model). This session describes the advantages, uses, and "cons" of both models.

VSTs

An insight into what virtual system tables (VSTs) are, as well as some code samples on how to use them. A very practical introduction to monitoring your system and using a sample toolset to build your own VST.

Resizable Screens

Window resizing is not something that comes naturally to most OpenEdge applications. Even when the window resizes, what do you do with the graphical objects inside it? Instead of "one size fits all", it’s more often a case of "no size fits at all". This presentation examines various algorithms for resizing and shows how to build and implement a Window template which will resize chosen objects in a variety of ways.
