A Better DosFileLookup2005-05-13http://www.clarionmag.com/cmag/v7/v7n05selectfile.htmlWhen 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)2009-04-30http://www.clarionmag.com/cmag/historyofclarion.htmlA recent discussion of DevCons past prompted Dave Harms to compile an incomplete history of Clarion.

A C7 Slider Control2009-05-29http://www.clarionmag.com/cmag/v11/v11n05slider.htmlClarion 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 Template2003-01-24http://www.clarionmag.com/cmag/v5/v5n01calc.htmlNardus 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 Browses2003-09-05http://www.clarionmag.com/cmag/v5/v5n09datedialogue.htmlOne 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 FileManager22006-12-21http://www.clarionmag.com/cmag/v8/v8n12fm2callback.htmlCapeSoft'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.

A Class  For Tagging2003-02-13http://www.clarionmag.com/cmag/v5/v5n02tags.htmlSteve 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 Addresses2002-10-03http://www.clarionmag.com/cmag/v4/v4n10addresses.htmlPrinting 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 ASCIIng2002-11-08http://www.clarionmag.com/cmag/v4/v4n11anyascii.htmlASCII 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 Buttons2004-03-26http://www.clarionmag.com/cmag/v6/v6n03menubutton.htmlNik Johnson gets his copy of Tips & Techniques and quickly discovers a solution to his screen real estate problem: Brice Schagane's menu button.

A Customized Deep Assign Function2006-12-12http://www.clarionmag.com/cmag/v8/v8n12deepassign.htmlThe 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 Content2005-11-30http://www.clarionmag.com/cmag/v7/v7n11conditionalfdb.htmlThere 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 Records2001-08-01http://www.clarionmag.com/cmag/v3/v3n7deletefmnotes.htmlDennis 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.

Classes For Background Processes2006-10-20http://www.clarionmag.com/cmag/v8/v8n10workerthread.htmlC6 introduced true threading and threads are a great way to handle background tasks. But threads seem very procedural - you start some code running and it runs until it ends. What if you want to use threads in an object-oriented environment? Is it even possible to have a class that runs on its own thread? How do you control threads in an object-oriented environment? David Harms demonstrates one approach to threading classes.

Compiled Reports From Report Writer2004-03-29http://www.clarionmag.com/cmag/v6/v6n03compiledreports.htmlAs far as Henry Plotkin is concerned the best thing about Clarion Report Writer is the ability to set up the finished page without having to adjust the position of each individual band. The next best thing about Report Writer is that report testing is much faster. It does not require a compile-link cycle. It does not require minimizing Clarion starting the application and navigating to the report. Wouldn't it be nice to be able to design reports in Report Writer and then just copy them into a Clarion report procedure? Actually it can be done and fairly easily.

Converting TPS Files To A New Layout Part 22005-03-04http://www.clarionmag.com/cmag/v7/v7n02converttps2.htmlNo matter how hard you plan your database design  sooner or later you will want to change the layout of your application's TPS data files.  In this second of two parts  Abe Jimenez describes the actual data conversion.
Converting TPS Files To A New Layout2005-02-24http://www.clarionmag.com/cmag/v7/v7n02converttps1.htmlNo matter how hard you plan your database design  sooner or later you will want to change the layout of your application's TPS data files.  Clarion has a mechanism for converting files in the dictionary editor but it doesn't work on files that contain BLOBs or arrays.  It also doesn't help if your application is installed in multiple sites where the Clarion dictionary editor is not available.  If you make changes to the file's structure and then distribute your application your end users will get that dreaded error 47. That is unless you do what Abe Jimenez does.
Converting Your Apps To C72009-12-21http://www.clarionmag.com/cmag/v11/v11n12conversiontips.htmlRuss Eggen covers some of the more common errors you can encounter when converting applications from C6 to C7 including window structure errors and phantom templates.

Date Checking Time Stamping2002-01-07http://www.clarionmag.com/cmag/v4/v4n01datestamp.htmlThere are a number of reasons why you might want your application to check and act on dates and times. Perhaps you want to time your software out after a certain number of days. If your software is a demo or leaseware the ability to do this is critical. Similarly if you want to run automatic end of day processing or check for fiscal year rollover you need to be able to verify dates. Steve Parker shows how it's done.
Date Filtering with MSSQL2004-06-22http://www.clarionmag.com/cmag/v6/v6n06sqldate.htmlWorking within the Clarion source with Clarion language statements and translating the filter to that needed by the SQL engine can become more complex than is really necessary.

Designing Clarion# Libraries2007-12-20http://www.clarionmag.com/cmag/v9/v9n12codelib.htmlCreating code libraries is considerably easier in Clarion# than in Clarion in part because you no longer need to declare prototypes to use library code. And .NET's namespaces make it easy to organize your code into a meaningful hierarchy. 
Designing Crosstab Reports In Clarion (Part 1)2001-09-11http://www.clarionmag.com/cmag/v3/v3n9crosstab1.htmlOne of the more common and useful reports is the crosstab report which can be defined as any report that summarizes data in a two dimensional grid such as breaking down sales data into monthly or quarterly sales. Other report writing tools often supply a wizard to guide the user through the process of creating this type of report. Clarion however leaves the programmer to his or her own devices to create this standard summary. Part 1 of 2.
