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 | http://www.clarionmag.com/cmag/historyofclarion.html | A recent discussion of DevCons past prompted Dave Harms to compile an incomplete history of Clarion.

A Class For Tagging | 2003-02-13 | http://www.clarionmag.com/cmag/v5/v5n02tags.html | 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 | http://www.clarionmag.com/cmag/v4/v4n10addresses.html | 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 | http://www.clarionmag.com/cmag/v4/v4n11anyascii.html | 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 | http://www.clarionmag.com/cmag/v6/v6n03menubutton.html | Nik 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 Function | 2006-12-12 | http://www.clarionmag.com/cmag/v8/v8n12deepassign.html | 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 | http://www.clarionmag.com/cmag/v7/v7n11conditionalfdb.html | 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 | http://www.clarionmag.com/cmag/v3/v3n7deletefmnotes.html | 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.

A String To CString Converter | 2003-06-26 | http://www.clarionmag.com/cmag/v5/v5n06cstring.html | Sometimes you need to pass CSTRINGs to a function and it's inconvenient to create variables for the purpose - you just want to pass in string literals. But Clarion (at least through version C6 EA4-5) all literal strings are STRINGs. So how do you do it? With a class of course. | |||

Adding Page Of Pages To A Clarion Report | 2002-08-16 | http://www.clarionmag.com/cmag/v4/v4n08pageofpages.html | For many years now it has been difficult to add a Page of Pages variable to a Clarion report. It has also been difficult to print more than one copy of a report without clicking on the print/report button twice or using the printer properties to specify multiple copies. Inspired by Bruce Johnson's ABC book and some conversations at ETC III Nardus Swanevelder finds a solution to both problems. | |||

Compiled Reports From Report Writer | 2004-03-29 | http://www.clarionmag.com/cmag/v6/v6n03compiledreports.html | As 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 | 2005-02-24 | http://www.clarionmag.com/cmag/v7/v7n02converttps1.html | No 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. | |||

Date Checking Time Stamping | 2002-01-07 | http://www.clarionmag.com/cmag/v4/v4n01datestamp.html | There 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 MSSQL | 2004-06-22 | http://www.clarionmag.com/cmag/v6/v6n06sqldate.html | Working 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. John Griffiths describes a neat trick for filtering dates in MS SQL. | |||
David Bayliss on FieldClass | 1999-04-12 | http://www.clarionmag.com/cmag/v1/v1n3dabonfieldclass.html | FieldClass is one of the smaller ABC classes but it's responsible for almost 30% of the reduction in generated code between the legacy and ABC templates.

David Bayliss On The ConstantClass | 1999-03-19 | http://www.clarionmag.com/cmag/v1/v1n2constantclass.html | The management of constants in an application presents a number of ticklish problems. As DAB writes Should I explain the design insights I should have had (as I can now see with perfect 20-20 hindsight) or should I detail the evolution of the Constant Class from the germ of an idea into one of the cornerstones of the system? | |||
David Bayliss On The ErrorClass | 1999-02-22 | http://www.clarionmag.com/cmag/v1/v1n1errorclass.html | David Bayliss begins his comprehensive series on the inner workings of ABC with a discussion of ErrorClass one of the most fundamental and basic ABC classes. | |||

But it isn't always easy viewing queue data when you're tracking down a queue data-related bug. To solve this problem Alan created a procedure that makes it easy to export queue data to Excel which is an excellent tool for viewing tabular data. | |||
Debugging SQL Problems With File Callbacks | 2007-09-19 | http://www.clarionmag.com/cmag/v9/v9n09callback.html | Sometimes database problems don't respond to the usual array of debugging tools. Marty Honea shows how to find out exactly what the driver is doing with file callbacks. | |||

But he did not consider multi-DLL applications. In this article he corrects his oversight. | |||
Designing Clarion# Libraries | 2007-12-20 | http://www.clarionmag.com/cmag/v9/v9n12codelib.html | Creating 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) | 2001-09-11 | http://www.clarionmag.com/cmag/v3/v3n9crosstab1.html | One 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. | |||
