Dealing with the Windows Registry
WinReg is part of the CategoryAplTree project.
Contents
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".

Restrictions
Note the following restrictions:
PutValue supports DWORDs (REG_DWORD)
PutBinary supports REG_BINARY
PutString and GetString support strings (REG_SZ), nested strings (REG_MULTI_SZ) and expanded strings (REG_EXPAND_SZ)
GetValue supports all data types.
Other data types can be requested via GetValue; however, writing them is not supported.
