When the debugger won't debug hidden code that isn't hidden
DominoPower Magazine - June 2009
Looking carefully at your workspace, you notice a strange little message in the status area: "Debug request ignored. Source code hidden." You're in Notes and you've enabled the debugger. Now, you attempt to debug a form or view action. It looks like your code executes, but the debugger is nowhere to be found.
What to do if the LotusScript debugger won't single-step over code
DominoPower Magazine - June 2009
If you've been attempting to debug LotusScript, particularly a piece of LotusScript with shared fields, you may have noticed that the Notes debugger itself needs a little debugging.
Little known traps about Lotus Notes fields
DominoPower Magazine - December 2008
Fields would seem to be simple things, places to put data items. But like much else in Notes, they're traps for the unwary. They're traps for more experienced developers too, just when you're looking somewhere else. In this helpful article, Senior Technical Editor Mick Moignard helps you avoid those traps.
Use the LotusScript Split function to write simpler code

Getting the Domino server time with @Now
DominoPower Magazine - July 2008
For a few years now, Senior Technical Editor Mick Moignard has been supporting a Notes application for a customer, and one of the pieces of functionality he wanted in the application for quite some time was to be able to record server, rather than client, clock times when users performed various actions. Even though there are all sorts of version compatibility issues, Mick figured out how to do it. This article explains it all.
Cache strategies with @Dblookup, and more
DominoPower Magazine - July 2008
One of the most common examples of less-than-perfect programming Senior Technical Editor Mick Moignard has seen in Notes is the use of @DBLookup or @DBColumn with no thought given to the caching of data -- every call specified with NoCache, because the developer wanted to be sure that data was freshly looked up. In this article, he discusses the right way to do it.
Recursion: the good, the bad, and the alternatives
DominoPower Magazine - June 2008
Sometime back, we looked at recursion as a way to solve some problems not easily solved in other ways. Unfortunately LotusScript recursion does have its limitations and in this article Ian Murray discusses how to discover what those limitations mean for you and your code, and how you can avoid them.
Fun with hidden code
DominoPower Magazine - March 2008

Numeric vs. text fields in application design
DominoPower Magazine - November 2007
When designing applications, consider carefully whether the value you are keeping really is a number that you will use in arithmetic calculations, or whether it is just a text string that contains numeric characters. You won't regret those few extra moments in your application design process when you see the extra robustness of the application and its greater resilience to change. In this helpful article, Senior Technical Editor Mick Moignard helps you understand where you could go wrong, even if you do it by the numbers.

A simple way of commenting if/else for better understanding
DominoPower Magazine - August 2004
When you code in LotusScript or maybe even Java, I am sure you use a lot of 'if then else' statements. The problem with nesting these statements that it is really easy to loose track of which 'end if' belongs to which 'if'.

Domino forms for all
DominoPower Magazine - October 2000
Wouldn't it be great if you could Domino-enable just one or two Web forms on any site, regardless of whether it was running ASP pages, static HTML, or being accessed by AvantGo users? Or, what if you could use standard HTML forms generated in any Web design package, yet have the forms fed automatically into Domino workflows? Well, Jeffrey R.

Using recursion in LotusScript
DominoPower Magazine - March 2000
LotusScript is a powerful programming language that gives developers the ability to utilize advanced programming techniques. One of these techniques is recursion. Many developers hesitate to use recursion, preferring to use techniques with which they're already familiar. But using recursive functions can greatly simplify your code, if you implement them correctly. In this article, Greg White will help you to navigate through recursion and learn to use it to simplify your programming.
LotusScript agents and the Web
DominoPower Magazine - February 2000
LotusScript Agents are powerful tools that can be used in a variety of ways. I often use them to move documents through an Approval Cycle by having the Approver click on a button to either Approve or Deny the document. This works well in Lotus Notes, but how do you get the same functionality over the Web? Chris Stoner explains that by using LotusScript Agents, it's really not that hard.

Access list management system
DominoPower Magazine - October 1999
Contributing Editor Dan Velasco has designed a system to provide "managers" of some databases with the ability to modify the access list for a database.

Fun with $FormulaClass

The $FormulaClass field exists on view design documents and controls what the view shows. What's extremely cool is that you can use LotusScript to change the value of this field and thus cause a view to show you Notes design documents rather than just plain old everyday documents. In this important article, contributing editor Dan Velasco shows you how.
Using one template for three different uses
DominoPower Magazine - June 1999
Have you ever wanted to create one template that can support multiple renditions of itself? For some applications, you may be maintaining a bunch of templates that are basically the same. If you make a design change to one, then all need to be updated! The design of these templates can quickly get out of sync. A better solution, given this scenario, would be to have one common template that adapted to your needs. This article by Chris Brown (a.k.a. GreenJellybean) explains how to do just that.
