WinReg: dealing with the Windows Registry

WinReg is part of the CategoryAplTree project.

Overview

This class offers methods useful to deal with the Windows Registry without using .NET. It uses ⎕NA calls to the appropriate Windows API.

WinReg is a powerful class that offers plenty of methods. If you just want to read, write and/or delete values from the Windows Registry then the much smaller class WinRegSimple might be sufficient.

Terminology

To understand the names of the methods you need to understand the terminology. If you find the terminology strange: so do I, but it was invented by Microsoft and therefore defines the standard. That is the reason why I decided to go for it: it makes it easier to understand the Microsoft documentation but also to understand others while talking about the Windows Registry.

In this picture:

you can see this string:

HKEY_CURRENT_USER\Software\Dyalog\Dyalog APL/W 12.0 Unicode\AutoComplete

at the top of the window.

HKEY_CURRENT_USER

This is called a "Main key". There are a number of pre-defined main keys available you can choose from. There is also a shortcut available: instead of HKEY_CURRENT_USER you can use HKCU.

SOFTWARE\Dyalog\Dyalog APL/W 12.0 Unicode

This is called a sub key.

On the right side you see a list. The entries in this list are called "values". Therefore CancelKey1 is a value.

Note that the names are called values; the actual data saved under a value is called "data".

APLTree downloads

Using an APLTree member

  1. If you just want to consume (use) an APLTree member then you have several choices:
    • Note that accessing it via ftp allows you to download older versions as well while the dedicated download page offers just the most current version.

Contributing

If you want to contribute to an APLTree project see HowToContributeToTheAPLTreeProject for details.

Get the full project

If for some reason you need access to, say, the test cases then you need to get more then just the script (or application) itself.

HowToContributeToTheAPLTreeProject explains how to get a project onto your local machine. Just ignore any additional steps.

Create a new APLTree sub project

In order to create a new APLTree project you need some advice. Ask KaiJaeger for help: mailto:kai@aplteam.com
