LC.Charts (freeware) v2.2 (Jan 25, 2015)

LC.Charts is 2D and now 3D! (discover the 10 types of 3D charts, new in v2.2)

APL is a fantastic, concise, beautiful and pure language that really deserves a much boarder exposure!

A single APL instruction often does the same job as a 20 or sometimes many more lines of code of a traditional language, and it is unique in the way it allows you to explore your data in the APL Session!

So it should also be possible to display your APL variables in a chart with a single instruction, right? This is what LC.Charts offers you.

But it goes much further as you can embed LC.Charts in your APL+Win forms and also create and customize them using ⎕wi.

And it's totally free: you can even include LC.Charts in your commercial products!

The following simple APL User Command creates a set of random data and produces the chart displayed below:

      ]chart3D ⎕split⍉?⌊.5+60 3⍴(⍳90)*.1×5+?5 /ti=3D-TrendSurface /zmaj=5 /ty=trendsurface

APL+Win v13.2 Released: APL+Win is now directly interfaced with Microsoft .Net! (Sep 4, 2013)

APL+Win v13.2 includes a few bug fixes and includes a brand new direct interface between APL+Win and Microsoft .Net through the use of the new ⎕CSE system function. Although it is still possible to create C# ActiveX DLLs that you can use from APL using NetAccess, it is now possible to directly embed and execute C# statements or scripts on the fly in your APL programs. It is also possible to load and use existing C# DLLs directly from your APL programs. This new APL+Win version requires the latest .Net Framework v4.5 version and gives access to its thousands of classes, as well as to countless third party .Net tools and controls available on the market. It will require that you learn (at least a bit of) C#, something that I have recommended to all my customers for the last few years.

New Product: SQL DLL©

SQL DLL© is a C# ActiveX DLL which gives any APL+Win (or Dyalog APL, VB6 or C#) developer direct and full easy access to MS Access and SQL Server databases.

The SQL DLL allows you to programmatically create, open and drop databases, perform any SQL query or nonquery on your database, create/remove primary keys and relations, etc.
It especially allows you to:

  • work with SQL Server local and remote databases
  • easily perform very fast bulk inserts to populate your tables with large amounts of data efficiently
  • easily perform very fast bulk updates to to change large amounts of records efficiently

New Product: Ribbon©

Ribbon© is a new product designed for APL+Win (and Dyalog APL) users to allow them create and use Office-like ribbons in their APL forms.

With the Ribbon© you can easily, at reduced cost, modernize your APL applications and greatly enhance their look and feel by replacing your application menus and toolbars by a Ribbon!

Ribbon© is delivered as a self-contained C# ActiveX DLL, as a workspace showing various Ribbon examples, including a Tutorial and as a User Command file. Ribbon© requires the .Net Framework 4 and APL+Win v3.0+ (or Dyalog APL v10+). Being a C# ActiveX DLL, Ribbon© can also be used from VB6 or any other product supporting ActiveX.

Here is a sample APL+Win form with a Ribbon:

APL form with a Ribbon control

New Product: SSGear©

SSGear© is a new product designed for APL+Win (and Dyalog APL) users which can also be used by any software supporting ActiveX.

It is a C# ActiveX DLL which allows you to work with Excel, but offers dramatic improvements over using Excel or Excel.Application directly from an APL+Win (or Dyalog APL) application:

  1. it is about 100 times faster than Excel and Excel.Application (or my TExcel5 object which is based on Excel.Application)
  2. it is more than 15 times faster than the APL+Win Grid which is known to be a pretty fast grid object
  3. it is compatible with Excel 2003, 2007, 2010 (including formatting, formulae, charts, printing engine, etc.)
  4. it can create/read/write .xls and .xlsx files
  5. it does not require Excel to be present on the computer
  6. it uses much less memory than Excel
  7. it can be embedded as a user control in an APL+Win (or Dyalog APL) form and be fully functional
  8. unlike Excel.Application, it is always cleanly erased from memory when the object is closed
  9. it can be used as a stand alone object (i.e. not child of a form), for example as a super printing engine to produce high quality APL reports
  10. it provides a much simpler API interface with only one object instead of the hundreds contained in Excel.Application you can easily use it with ⎕WI from APL+win (and you can use it as well directly from C#)
  11. it can load enormous amounts of APL data in very little time (780 milliseconds to display a 100000 by 5 APL matrix and 4.125 seconds to diplay a 500000 by 5 APL matrix for example)

APL+Win v11.1 Released (Dec 27, 2011)

APL+Win v11.1 includes:

  • A new Virtual APL Keyboard GUI Control
  • A new APL Idioms Manager Control

APL+Win v11.0 Released (Nov 8, 2011)

APL+Win v11.0 includes enhancements to the APL+Win Installer, Interpreter, Documentation, Help Files and Session. Read more...

Consulting Proposal

If you have an APL+Win (or Dyalog APL) application and would like to:

I'd be glad to help and develop for you a C# ActiveX DLL that you will then be able to use with ⎕wi from APL+Win.

As an example, I have recently written a C# ActiveX DLL for a customer; it allowed to speed-up an APL process on a large file so that it now runs more than 20 times faster! This DLL also allowed to process very large files (1.8 GBytes) without any memory problems.

Free C# ActiveX DLL

The LC.Goodies.dll is a free ActiveX C# DLL, developed with NetAccess 4.0 which includes all the properties and methods of the .Net Framework System.Environment class. Anyone can download it: it's free and can be used without any restriction even in product you sell. Being an ActiveX it can be used from APL+Win, Dyalog APL, VB6 and any other product supporting ActiveX. Download and read the accompanying LC.Goodies.chm Help File for details.

APL+Win v10.3 Released (Dec 29, 2010)

C# & APL+Win Class Attendees

The C# & APL+Win April 24-25 Class in Bethesda has gathered 19 attendees demonstrating the raising interest that APL+Win Users have in interfacing their APL applications with C#.

Convert your APL Applications to .Net!

This Web Site is about interfacing APL+Win and .Net C# as well as converting your APL+Win applications to .Net C#

There are numerous ways by which you can interface APL and C#.

This Web Site explains all the possibilities you have to use the full power of C# and of the .Net Framework with APL: all of them involve learning a bit of .Net and of C#. This Web Site will help you do that.

Among all these possibilities, the best one is to convert your APL application to C#: this does not mean rewriting your entire APL application in C#: it means rewriting your application User Interface in C# and use APL in the background for the remaining part of your application that can basically stay unchanged.

Reading this Web Site you'll learn:

  • how you can write C# DLLs which you can then use as ActiveX from APL+Win (see Use C# From APL)
  • how you can write C# applications which use your APL+Win workspace in the background (see Use APL From C#)
  • how you can convert your APL applications to .Net C#
  • how you can run your C# & APL+Win applications as ClickOnce applications from the browser

Learning C#

If you want to convert your APL application to .Net, you'll need to learn a bit of C# and a bit of the .Net Framework.

Learning C#, Visual Studio and the .Net Framework is easy and in any case much easier than learning APL.

Learning a bit of C# will allow you to move your APL application to .Net. while still keeping a large part of it in APL.
