#FINDing Values In Prefixed Structures | 2008-11-28 | If your template needs to #FIND prefixed local or global data you may have a problem (at least prior to C7 and maybe C6 9059). Lee White's template code offers a fix for #FIND. | |

.NET Basics: What Is .NET And Why Should I Care? | 2005-09-15 | You've heard the pitch before: Microsoft's .NET is the future and Clarion.NET is the future of Clarion. But really should you care? And what is .NET anyway? David Harms answers these and other questions. | |

A Basic Editor For Text Fields: Conclusion | 2003-09-11 | Clarion's TEXT control is versatile and useful but has next to no word processing capabilities. But as Tim Phillips shows it's relatively easy to add capabilities like search/replace block reformatting and more. Part 2 of 2. | |

A Better DosFileLookup | 2005-05-13 | When some standard Clarion functionality doesn't meet your need what do you do? First you embed some code. Then when you need that code elsewhere you start thinking about how to avoid duplicating the embeds. As Dave Harms shows often the easiest solution is to create a custom derived ABC class and tell the templates to use your class instead of the ABC original. | |
A Brief History of Clarion (Updated) | 2009-04-30 | A recent discussion of DevCons past prompted Dave Harms to compile an incomplete history of Clarion. Updated April 29 2009 with more conference info. To leave a comment log in (subscription not required). | |
A C6 Tagging Class Template Wrapper | 2003-08-07 | Steve Parker recently published an article on an ABC compliant class for tagging on browses. When someone requested a template-enabled version Jim Katz volunteered his services and along the way discovered that creating a C6 ABC class template wrapper is easier than it used to be. In this second of two parts Jim concludes the template code. | |

A C7 Slider Control | 2009-05-29 | Clarion Magazine last published an article on slider controls ten years ago and unfortunately that code no longer works in Clarion 7. Here's a version by Lee White and Bob Dobbins that gets the job done. | |
A Calculator Class And Template | 2003-01-24 | Nardus Swanevelder's search for a free XP-like Clarion calculator was fruitless but he found some free Clarion 4 source code. Nardus shows he he converted that source into a class and templates. | |
A Calendar For Date-Limited Browses | 2003-09-05 | One of the most-used features of Clarion is page-loaded browse boxes. But are these really a good idea? Veronica Chapman suggests otherwise and illustrates this with a calendar you can use to date-limit a file loaded browse box. | |
A Callback Technique for Capesoft's FileManager2 | 2006-12-21 | CapeSoft's FileManager2 and its more recent incarnation FileManager3 are amazing products: they completely automate the process of upgrading client databases whether local or across a network and make it easy to do file maintenance. Randy Rogers shows how to add a callback procedure to FM2 to provide user feedback during startup. | |
A Class For Tagging | 2003-02-13 | Steve Parker is on record as not feeling the need to create classes. Yet here he is creating a class version of his tagging code. It's the end of the world as we know it. | |
A Class For Printing Addresses | 2002-10-03 | Printing street addresses on reports can be a pain - missing field data can make a good report ugly in a hurry. One way around this is to use a memo for addresses but then you still have to format sometimes wildly different address data. Here's a small class that makes short work of address formatting. | |
A Class For The ASCIIng | 2002-11-08 | ASCII files are commonplace in programming but their use in Clarion is generally more complicated than in other languages because Clarion can only do ASCII file I/O via an ASCII file driver declared file. Declaring such a file can become quite a nuisance and breaks Konrad Byers' golden rule of never having to program the same thing twice. Enter the any ASCII file class. | |
A Class Wrapper for Brice Schagane's Menu Buttons | 2004-03-26 | Nik Johnson gets his copy of Tips & Techniques and quickly discovers a solution to his screen real estate problem: Brice Schagane's menu button. For easier re-use Nik shows how to convert Brice's code into a class. | |

A Class Wrapper for the SimpleOCR API | 2006-07-06 | While developing a document management system John Dunn faced a requirement for scanned documents.

A Configurable Expression Editor Part 2 | 2004-11-19 | Since Clarion does not have a good integral tool for defining an expression at runtime Tim Phillips went ahead and built one using his Basic Editor as the foundation. In this second of two parts Tim shows how the code works. | |
A Copy/Paste Popup Menu | 2004-12-10 | Clarion entry controls may have support for Ctrl-C and Ctrl-V for copy and paste but what do you do when a client asks for the Copy/Paste popup menu? If you're Nardus Swanevelder you start writing some code. | |
A Customized Deep Assign Function | 2006-12-12 | The deep assign operator (:=:) is a powerful tool but it doesn't work in all circumstances. Alan Telford shows how to extend deep assign functionality using WHO and WHAT. | |
A FileDropBox With Conditional Content | 2005-11-30 | There are always situations where the contents of a FileDropBox either a FileDropListBox or a FileDropCombo is dependant on some criteria usually the contents of an entry field or another FileDropBox. But a FileDropBox is always file loaded and this loading is done when the form opens after that the FileDropBox remains pretty static. Maarten Veenstra shows how to change the FileDropBox's content at runtime. | |
A FileManager For Marked Deleted Records | 2001-08-01 | Dennis Evans recently created a template and two classes to manage records marked as deleted (rather than physically deleted) as described in a recent ClarionMag article. This page contains usage notes on the class and a link to the source. | |
A Fresh Look At ClarionTest | 2011-08-30 | It's almost two years since Dave Harms wrote ClarionTest 1.0 an NUnit-inspired testing framework for Clarion Win32 programming. And although ClarionTest has been shown on ClarionLive it hasn't had much coverage here at home. Dave remedies that with the first article in a series on this increasingly popular utility. | |
A Function to Return Clarion Standard Time | 2004-07-16 | Mark Riffey made the request: I want to do TIME('12''24''06') and get a Clarion [standard] time just like I would do DATE('12''24''2004') and get a Clarion date. Steve Parker with a little help from his friends shows how it's done. | |
A Hunka-Hunka Burnin' CD Data or Two Steps Forward One Step Back(up) | 2004-04-15 | An integrated backup system can be a great way to provide complete service to your customers.

A Multi-Threaded Queue Of Queues | 2005-06-21 | Queues make all kinds of data handling fast and easy.

Svetlana Zusman shows how to lock nested queues for thread safety and maximum efficiency. | |
A Naïve Look At Pre-Emption | 2003-03-20 | Steve Parker knows that with Clarion 6 on the horizon global data abuse has to be dealt with beginning with his own applications. | |

A Simple Versions And Annotations Template | 2003-12-05 | Recently Ronald van Raaphorst realized he needed some kind of annotation system for his Clarion app. The result was this template that lets a developer record changes in any procedure and print an overview of all annotations per procedure or application. |
