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.

Dual or Quad Core For Clarion?2008-11-17http://www.clarionmag.com/cmag/v10/v10n11dualvsquad.htmlA new release of Clarion is a good excuse as any for a new development box even if code generation and compiling are already faster. But what processor to choose: dual core or quad core? 
Dynamic Filters: Applying The Theory2001-04-03http://www.clarionmag.com/cmag/v3/v3n4dynamicfilters2.htmlDr. Parker having dealt with the theory of dynamic filters goes on to some sample code which ranges from the sublime to the ridiculous.
Dynamic Filters: The Theory Behind the Facts2001-03-27http://www.clarionmag.com/cmag/v3/v3n3dynamicfilters1.htmlClarion’s templates hide complexity. The ABC classes are supposed to also. But too often we developers re-introduce complexity.Once you realize that filters can be created in only two ways it is really much easier to optimize filter expressions and performance. Part 1 of 3.
Dynamic Table-Based Tagging2004-09-17http://www.clarionmag.com/cmag/v6/v6n09tagging.htmlSometimes a simple tagging solution is the ideal solution and sometimes you need something a bit more robust.

Dave Harms provides some preliminary results on typical usage from the ClarionMag embed analysis project.
Embedding Fonts In Clarion Apps2005-01-14http://www.clarionmag.com/cmag/v7/v7n01embedfonts.htmlEmbedding resources into a program is common practice in Windows programming. Surely Clarion must be able to use the Windows Resource file system to access a font stored away as a binary resource. But how does Clarion handle this? David Bratovich explains.
Embedding The SQLite Engine In Clarion Applications2007-02-27http://www.clarionmag.com/cmag/v9/v9n02sqlite.htmlSQLite is a public domain lightweight embeddable SQL database which is fast and stable and can create both disk and in-memory tables. John Taylor presents a wrapper class that makes it easy to use SQLite in your Clarion app. 
Encrypting Data With Number Base Conversion2006-03-02http://www.clarionmag.com/cmag/v8/v8n02convertbase.htmlMost programmers are familiar with base 2 (binary) numbers base 10 (decimal) and base 16 (hex). But using arbitrary number bases can also be a useful way to encrypt data for transmission by phone or other voice methods. Dermot Herron shows how he applies this technique to transfer vital information to customers.
Enhancing The RoundedPanel Control2008-05-01http://www.clarionmag.com/cmag/v10/v10n05roundedrectangle.htmlDave Harms follows in Randy Rogers' footsteps and comes up with a few enhancements to the Clarion# RoundedPanel control.
Enriching The User's Experience With RTF Displays2005-03-11http://www.clarionmag.com/cmag/v7/v7n03rtf.htmlText is becoming more and more of a requirement for applications and large text fields have never displayed comfortably within the Clarion list box. Stephen Bottomley shows how easy it is to use RTF to create a custom display format for your data.
Ergonomics For Programmers2008-02-12http://www.clarionmag.com/cmag/v10/v10n02ergonomics.htmlAll too often programmers ignore ergonomics when setting up an office. They'll spend time and energy researching what is the best computer system which monitor to choose and which software will do the job but often don't give much if any thought to the physical stresses they'll experience if their desk chair monitor keyboard or mouse are incorrectly positioned. Robert Johnson explains how to set your office up the right way.

Newsgroups Slow? Use a Hamster.2009-04-03http://www.clarionmag.com/cmag/v9/v9n02hamster.htmlI've been hearing lately about the SV news server running slowly. Maybe it's just my connection but I've always found that to be the case which is why a couple of years ago I followed CapeSoft's lead and set up Hamster as an intermediary. If you want to speed up your newsgroup access check out this article from 2007. 
Next Month Anniversary Date Function2006-01-19http://www.clarionmag.com/cmag/v8/v8n01datemonth.htmlInspired by Carl Barnes Better Date article John Griffiths offers up this function to get anniversary dates on specific days of the month.
Nifty Window Tricks And Smart DLL Loading2006-04-20http://www.clarionmag.com/cmag/v8/v8n04transparent.htmlIt's an age old question: How do I use a Windows API function that is not available in all versions of Windows?  The simple answer is that you only call the function if it's available at runtime.  You do this by attempting to dynamically load the module where the function resides and if that succeeds you call the function by address.  If you can successfully load the module and get the address of the procedure it exists in this version of Windows.  There's no need to try to identify the version of Windows  either the function exists or it doesn't. In this article Larry Sand demonstrate this technique with some API calls that are only available in Windows 2000 and later and which allow you to gradually fade in a window and make an area transparent or opaque. 
No More Tight Loops2008-01-31http://www.clarionmag.com/cmag/v10/v10n01tightloops.htmlA tight uninterruptable loop is fine when processing takes a very short time but is often unacceptable for longer processes. Maarten Veenstra shows how easy it is to change your tight loops to timer-based loops.

No! You Can't Cancel2006-12-13http://www.clarionmag.com/cmag/v8/v8n12nocancel.htmlClarion developers are a nasty bunch. They do not want to let their end users cancel forms. At least it seems so from the frequency with which questions are asked about trapping the Escape key or Windows' red X. Dr. Parker shows how it's done.
Normal Files Normal Display2001-09-10http://www.clarionmag.com/cmag/v3/v3n9normal.htmlOne of the basic concepts of normalization is that every record in a file or row in a SQL table should be uniquely identified. Steve Parker  addresses two aspects of unique IDs: the generic motivation for using them and the difficulties they can present when displayed to the end user.
Not Having Six Makes Me Cranky2002-10-15http://www.clarionmag.com/cmag/v4/v4n10guestcranky.htmlWhy must SoftVelocity call the next release 5.6? Some say it's because at DevCon98 Bruce Barrington promised that version 6 would be 32-bit. Well Carl Barnes was there and he has a differing opinion.
Notifying ClarioNet Clients With PushWindow2005-02-25http://www.clarionmag.com/cmag/v7/v7n02pushwindow.htmlClarioNet is designed to so that the server responds only when the client makes a request to minimize the amount of network traffic.

PROP:SQL And Embedded Single Quotes2006-03-10http://www.clarionmag.com/cmag/v8/v8n02quotes.htmlIf you use MS-SQL with your Clarion programs and you write your own SQL statements then you've probably run into problems with quote characters. SQL statements use quote characters to delimit streams and if you have quotes inside your strings you need to double them up so MS-SQL doesn't treat them as the end of the string. This article by John Griffiths will show you a few quoting tricks and will also provide you with a handy function - SingleQuoteDoubler()

The Problem With Embeds Part 1: What Went Wrong?2009-09-28http://www.clarionmag.com/cmag/v11/v11n09problemwithembeds1.htmlAs Clarion developers we (well most of us) live and die by embed code. Embeds are after all at the heart of Clarion's effectiveness. They're the primary way we add custom code to applications that are otherwise template-generated. And if you're like most Clarion developers you're probably using embed points the wrong way. Without realizing it you're making your applications more difficult to maintain harder to debug and almost impossible to document.

Tip of the Week: Multiple Installs2011-06-24http://www.clarionmag.com/cmag/v13/v13n06tip27.htmlKeeping separate installs for every version of Clarion can make it much easier revert to an earlier build. 
Tip of the Week: Optional Return Values2011-09-23http://www.clarionmag.com/cmag/v13/v13n09tip34.htmlSometimes you don't need a return value from a certain procedure or method. But not receiving one leaves you with a compiler warning. 
Tip of the Week: Searching/Finding Files Using Redirection2011-02-27http://www.clarionmag.com/cmag/v13/v13n02tip12.htmlBoth Clarion 6 and Clarion 7 make use of the redirection file to help you find your own source but Clarion 6's approach still wins. 
Tip of the Week: Side By Side Windows2011-01-27http://www.clarionmag.com/cmag/v13/v13n01tip8.htmlSure you can open multiple apps at the same time in C7 and dictionaries and other files as well. But that's just the beginning - you can also also view those windows side by side.

TopSpeed INI Files2002-09-13http://www.clarionmag.com/cmag/v4/v4n09ini.htmlINI files are handy but not always the best way to store initialization information in an already database-enabled application. As it turns out it's not that difficult to use TPS (or other database files) as drop-in replacements for text INI files in ABC applications. In this article Tim Phillips explains how you can extend the ABC IniClass with just 25 lines of code and drop in your own INI file handler.

Trading Global Data for Data Obfuscation Sort Of...2008-10-23http://www.clarionmag.com/cmag/v10/v10n10globals.htmlPopular opinion to the contrary global data is (or at least can be) a good thing. You wouldn't get far without it. Like any data you create it should be used when it is the best fit for the need at hand and with thoughtful consideration of its implementation and access methods. Mark Geisinger presents a class for managing multi-APP global data in a way that doesn't require you to recompile all your apps every time the data definition changes.

And he discovers that contrary to popular opinion it can be done.
Trees Recursion and Many to Many Checkboxes2003-10-17http://www.clarionmag.com/cmag/v5/v5n10treecheck.htmlMost of the data you deal with probably fits nicely into a parent/child relational data structure. But sometimes you have data that works better as a self-join where data in one table relates back to other data in the same table. Randy Long shows how to use trees recursion and many-to-many checkboxes to manage this kind of data.
True Confessions: A Tale of Two Users2000-06-20http://www.clarionmag.com/cmag/v2/v2n6confessions.htmlThe cost of knowing what you are doing is having learned the hard way. Somehow it doesn’t matter how many books manuals articles or true confessions you read you never really learn until you’ve made the painful mistake yourself.
True Threading: What You'll Need To Know2001-08-15http://www.clarionmag.com/cmag/v3/v3n8threading.htmlMultitasking is an important part of Windows application development  we’ve all become used to running multiple applications at once and most of us create MDI applications which can have multiple windows open each on its own thread. Clarion does this sort of thing well for the most part. So what’s the problem and why are developers pushing for true threading support in Clarion?
UK CUG Report on C7/Clarion.NET2006-08-05http://www.clarionmag.com/cmag/v8/v8n08ukcug.htmlRichard Rose reports on the UK CUG meeting including news on Clarion 7 Clarion.NET and the new IDE. 
Understanding Clarion Templates Part 12004-03-26http://www.clarionmag.com/cmag/v6/v6n03templates1.htmlTemplates! Templates! Templates! That for many years has been the Clarion rallying cry (unless you prefer David Bayliss's Don't Know Don't Care! from DevCon '97). And despite the advance of Clarion OOP technology templates are still what Clarion does best. But what are the templates really? David Harms begins this series with an overview of template types.
Understanding Clarion Templates Part 22004-03-31http://www.clarionmag.com/cmag/v6/v6n03templates2.htmlIn this second article in his template series David Harms takes a closer look at the template language itself.
Understanding Clarion Templates Part 3: Introducing Code Templates2004-04-23http://www.clarionmag.com/cmag/v6/v6n04templates3.htmlThe Clarion template system is at heart a simple idea. If you want to generate code based on varying conditions and requirements you just create a template programming language that lets you generate Clarion language statements. Okay maybe the reality isn't all that simple but the easiest place to start understanding the template language is with code templates as David Harms explains.
Understanding Clarion Templates Part 4: Writing Code Templates2004-05-11http://www.clarionmag.com/cmag/v6/v6n05templates4.htmlDavid Harms continues his series on learning the template language with an introduction to writing code templates.
Understanding Clarion Templates Part 5: Enhancing Code Templates2004-05-21http://www.clarionmag.com/cmag/v6/v6n05templates5.htmlIn this instalment on code templates David Harms shows how to properly display text in a template and conditonally generate code.
Understanding Clarion Templates Part 6: Using #GROUPs2005-01-20http://www.clarionmag.com/cmag/v7/v7n01templates6.htmlDave Harms continues his template writing series with an explanation of #GROUP structures which are really template language procedures.
Understanding Clarion VIEWs Part 12009-02-11http://www.clarionmag.com/cmag/v11/v11n02views.htmlDespite being in the language for more than 10 years now VIEWs remain largely unknown to most Clarion programmers. Bruce Johnson shows how easy it is to define and use views. Part 1 of 2.
Understanding Clarion VIEWs Part 22009-02-11http://www.clarionmag.com/cmag/v11/v11n02views2.htmlHaving showed in Part 1 how easy it is to define and use views Bruce Johnson covers the key features of view orders and filters. Part 2 of 2.
Understanding Clarion# Attributes2008-05-31http://www.clarionmag.com/cmag/v10/v10n05attributes.htmlIf you've looked through the Clarion# example apps you may have noticed some strange code contained inside square brackets. Those are attributes and as Dave Harms explains they're a way of adding useful information to your code so that other code knows what to do with your code? Confused? Read on...
Understanding Clarion# Delegates2008-11-26http://www.clarionmag.com/cmag/v10/v10n11delegates.htmlClarion# introduces a number of important new concepts inluding delegates and events. Delegates which form the basis for .NET events are much like WinAPI callbacks but with a few important differences. Randy Rogers and Dave Harms explain. 
Understanding Clarion# Events2008-11-26http://www.clarionmag.com/cmag/v10/v10n11events.htmlEvent handling in Clarion# (as in other .NET languages) is a potentially confusing subject. But as Randy Rogers and Dave Harms demonstrate an EVENT in Clarion# is really just a special kind of delegate. 
Understanding Clarion# Strings2007-12-10http://www.clarionmag.com/cmag/v9/v9n12clarionsharpstrings.htmlThere are some significant differences between Clarion strings and .NET strings. Clarion# introduces the ClaString class which for the most part allows Clarion# to use strings the same way classic Clarion uses strings. Here's what you need to know about this new data type.
Understanding Clarion# Strings: Revisited2008-02-29http://www.clarionmag.com/cmag/v10/v10n02clarionsharpstrings.htmlThe latest changes to class instantiation and array indexes in Clarion# have implications for string handling. Dave Harms takes a close look at the ClaString and String data types. 
Understanding Field History2011-06-28http://www.clarionmag.com/cmag/v13/v13n06history.htmlHow can you tell if a specific field has changed? How can you know the previous value? How can you know if the record has changed. The Steve knows. 
Understanding OOP Interfaces2000-01-18http://www.clarionmag.com/cmag/v2/v2n1interfaces.htmlDavid Bayliss explains the inner workings of the new INTERFACE statement and compares Clarion's implementation to Java's.
Understanding Recursion - Part 12001-08-03http://www.clarionmag.com/cmag/v3/v3n7recursion1.htmlWhat is recursion? Ask that question of any group of developers and chances are pretty good you will receive several different answers. Some of the answers will be correct and others will be...interesting.
Understanding Recursion - Part 22001-08-08http://www.clarionmag.com/cmag/v3/v3n8recursion2.htmlWhat is recursion? Ask that question of any group of developers and chances are pretty good you will receive several different answers. Some of the answers will be correct and others will be...interesting. Part 2 of 2.
Understanding Stack And Heap Memory In 32 Bit Clarion Applications2001-06-05http://www.clarionmag.com/cmag/v3/v3n6memory.htmlIn Clarion as well as in C and C++ (and unlike Java) you need to be aware of possible memory leaks and thus be aware of the side effects of declaring variables. John Gorter explains how 32 bit Clarion applications use stack and heap memory.
Understanding Template Symbols2002-08-27http://www.clarionmag.com/cmag/v4/v4n08templates1.htmlIn this article Steffen Rasmussen introduces his preferred workflow for tackling more advanced template programming. He demonstrates his five step approach with a template for Dave Harms' many-to-many checkbox class.
Understanding The C7 Build System2008-10-30http://www.clarionmag.com/cmag/v10/v10n10solutions.htmlClarion 7 introduces a powerful new build system capable of handling multi-app solutions and much more. Dave Harms looks at the basic concepts of solutions and projects. 
Understanding The Clarion 6 Version Control Interface2006-03-16http://www.clarionmag.com/cmag/v8/v8n02cvs.htmlClarion 6's version control interface made it possible to use all kinds of version control systems but Benjamin Dell discovered the VCS products he tried did not give him nearly the same capabilities that the Clarion 5.5 VCS system had for concurrent developer control. That led him to an investigation of what the cryptic VCS help information in the Clarion Help file actually meant.
Undocumented Debugging1999-08-17http://www.clarionmag.com/cmag/v1/v1n7undocumentedclarion.htmlUndocumented functions - there's always a risk in using them because they might go away in the next release but sometimes they're worth a look. Here are four undocumented Clarion functions that can help you debug your applications.
Unit Testing Webinar Workshop Takes On Dates/Times2011-03-31http://www.clarionmag.com/cmag/v13/v13n03datetimetests.htmlRecently John Hickey and David Harms hosted a webinar workshop on unit testing using Pierre du Toit's article on Clarion and Excel dates and times as a source for a utility class. John and Dave learned a few things about the process and hopefully the participants did too. 
Updating Hot Fields2006-04-11http://www.clarionmag.com/cmag/v8/v8n04hotfields.htmlOn a browse window Hot Fields significantly extend the display of information. Fields for which there is no space in the list control data from other files (related or not) run time computed data are all nicely handled with Hot Fields. But when Steve Parker experiments with read-only entry fields on a browse he finds out his users now want to use these fields update values. 
Using A Browse Popup Menu For Lookups2007-06-26http://www.clarionmag.com/cmag/v9/v9n06popup.htmlThe standard way to handle an update is to select the record bring up the form make the changes and save. But sometimes a faster method is called for: Murray Gillespie shows how to use a browse popup menu for quick lookup-based updates. 
Using API Threads - Part 12000-07-18http://www.clarionmag.com/cmag/v2/v2n7apithreads1.htmlClarion does an excellent job of managing threads for the developer but there are times when the standard thread handling just doesn't cut it. Jim Kane shows how to safely use API threads in Clarion.
Using API Threads - Part 22000-07-25http://www.clarionmag.com/cmag/v2/v2n7apithreads2.htmlClarion does an excellent job of managing threads for the developer but there are times when the standard thread handling just doesn't cut it. Jim Kane shows how to safely use API threads in Clarion.
Using Arrays in Databases2004-12-23http://www.clarionmag.com/cmag/v6/v6n12dbarrays.htmlArrays in databases? You can't in SQL and you shouldn't in TPS! But there are times when arrays really do make sense. Dermot Herron shows how to use OVER to get the benefits of arrays with non-arrayed file layouts.
Using CHOOSE With PROP:SQL2008-01-10http://www.clarionmag.com/cmag/v10/v10n01choose.htmlChoose is a very powerful addition to the Clarion language. But what if you want to use Choose-style syntax to PROP:SQL? Steve Parker explains how it's done.
Using CHOOSE() To Concatenate Data2000-09-15http://www.clarionmag.com/cmag/v2/v2n9choose.htmlIf you're used to concatenating strings the traditional Clarion way you'll want to read what Carl Barnes has to say about concatenating with the CHOOSE() function.
Using Clarion With MySQL - Part 12000-04-04http://www.clarionmag.com/cmag/v2/v2n4mysql1.htmlIn the first of three articles on Clarion and MySQL Dave Harms discusses installing Linux and the MySQL database server.
Using Clarion With MySQL Part 22000-04-11http://www.clarionmag.com/cmag/v2/v2n4mysql2.htmlIn Part 2 of this three-parter Dave Harms explains how to configure MySQL permissions to allow a Clarion application to connect to MySQL running on Linux.
Using Clarion's Business Rules Part 12004-10-21http://www.clarionmag.com/cmag/v6/v6n10bizrules1.htmlNardus Swanevelder begins a new series of articles explaining how to use Clarion's business rules capability to make your data validation flexible and configurable.
Using Clarion's Business Rules Part 22004-10-29http://www.clarionmag.com/cmag/v6/v6n10bizrules2.htmlIn Part 2 of this series Nardus Swanevelder explains the inner workings of the RulesManager class.
Using Clarion's Business Rules Part 32004-11-05http://www.clarionmag.com/cmag/v6/v6n11bizrules3.htmlNardus Swanevelder concludes this series by demonstrating how to implement dynamic business rules.
Using Clarion.NET's Easier Interop2011-08-31http://www.clarionmag.com/cmag/v13/v13n08interop.htmlClarion.NET now provides a much easier way to call .NET code from your Clarion Win32 applications. Graham Dawson provides an example and then uses that example to show exactly how Clarion.NET does its magic. 
Using Client-Side Triggers In Clarion 62004-03-26http://www.clarionmag.com/cmag/v6/v6n03triggers.htmlClient-side triggers are a new very neat and useful feature that has been added to Clarion 6 both Professional and Enterprise versions.  Tom Giles provides an introduction.
Using DOS Files To Send Printer Codes2006-03-31http://www.clarionmag.com/cmag/v8/v8n03portdriver.htmlIf your applications need to talk directly to printers on parallel ports or to serial devices you can use the Windows API. Or as Olivier Cretey explains you an simply use a Clarion DOS file.
Using Dynamic Filter Expressions for QBE2008-04-11http://www.clarionmag.com/cmag/v10/v10n04filters1.htmlPaul Blais takes a look at filter expressions employed in the Clarion VIEW structure. These expressions are a close cousin to EVALUATE and a great way to enhance your users' ability to query the database. 
Using Dynamic Indexes With TPS Files2001-06-08http://www.clarionmag.com/cmag/v3/v3n6dynindex.htmlDynamic indexes are often overlooked as a way to efficiently access data from TopSpeed (TPS) files especially if you are dealing with files that hold large numbers of records and a custom sort order and filtered subset is required.  By using a dynamic index you can eliminate the need to create additional file keys.
Using Example Files With TPSFix2001-08-10http://www.clarionmag.com/cmag/v3/v3n8tpsfix.htmlSometimes TPS files continue to get corrupted even after you run TPSFIX. John Heck shows how to use example files to fix corrupted headers once and for all.
Using GetLastError and FormatMessage to Check the Network2005-12-15http://www.clarionmag.com/cmag/v7/v7n12checknetwork2.htmlAs Henry Plotkin discovered in his previous article IsDestinationReachable is a less-than-perfect API call for detecting network problems. In this instalment Henry expands his analysis with the GetLastError and FormatMessage calls.
Using HTMLHelp with Clarion2008-12-23http://www.clarionmag.com/cmag/v10/v10n12htmlhelp.htmlClarion's default approach to Help has always been via WinHelp using *.HLP files to store the material. Although WinHelp still works it's now considered an unacceptable method. A better approach is to use compiled HTML help as Mike Hanson explains. 
Using IMAGE As A Scrollable Region2008-09-22http://www.clarionmag.com/cmag/v10/v10n09scrolling.htmlThere are several ways to make a scrollable region within a Clarion window including creating a scrolling window on a separate thread and using a list box to manually reposition controls. A cleaner solution as Bjarne Havnen shows is to use a scrolling IMAGE control as the parent for the form controls. 
Using Inheritance To Create Flexible Applications2008-03-20http://www.clarionmag.com/cmag/v10/v10n03inheritance.htmlIf you've ever had to create two versions of the same application you know the meaning of hair loss. But it doesn't have to be that way  tools and language features are available to ease the development of adaptable configurable applications including the mainstay of object-oriented programming inheritance.
Using Interfaces And Composition To Create Flexible Applications2008-03-20http://www.clarionmag.com/cmag/v10/v10n03interfaces.htmlWhen it comes to designing flexible adaptable applications most object-oriented programmers probably think of inheritance and virtual methods first. But interfaces are an equally powerful tool and when combined with composition you have an excellent toolset for making your applications highly configurable. 
Using KEYSTATE For Backdoors And Other Tricks2002-02-01http://www.clarionmag.com/cmag/v4/v4n01keystate.htmlThe Clarion KEYSTATE function returns the status of the shift type keys (Shift Ctrl Alt) the lock keys (Caps Lock Num Lock Scroll Lock) and the Insert key (overwrite or insert). It might sound like KEYSTATE isn’t good for much more than displaying information on the status bar but in fact this function is a great tool for detecting unusual keystroke combinations (including when the numeric keypad has been used) which you can use to implement hidden features in your applications.
Using Local Classes Instead Of Local Routines2005-08-11http://www.clarionmag.com/cmag/v7/v7n08localclass.htmlLocal classes are often touted as a replacement for procedure routines. But what are local classes why do you need them and what can you do with them? Nardus Swanevelder answers these questions and shows how easy it is to use local classes.
Using MATCH In Filters and Regular Expressions2001-07-03http://www.clarionmag.com/cmag/v3/v3n6match.htmlFilters for reports and browses seem to get increasingly complicated over time.

When Not To Generate Code2010-07-20http://www.clarionmag.com/cmag/v12/v12n07gotoerror.htmlThere's an odd setting in Application Options that tells the IDE to edit source errors from code embeds in the generated source rather than inside the app itself. That seems like a useless option to have but in fact it's qutie valuable as Dave Harms explains. 
Where ... Stuff Occurs: Deriving the FileManager2010-03-30http://www.clarionmag.com/cmag/v12/v12n03derivefm.htmlSometimes embedding custom CRUD code in browses or forms is the right way to go but if you want to apply that code application wide you might consider deriving the FileManager.
