Reads string from registry key.

 

Unit

EConfig

 

Syntax

 

Code (Delphi)

function RegKeyRead(

const ARoot: HKey;

const AKey, AName: String;

const ADefault: String = ''

): String;

 

Parameters

ARoot

One of predefined HKEY_XYZ constants. Usually it's HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE.

 

AKey

A full absolute path to key.

 

AName

A name of value to read.

 

ADefault

Optional default value.

 

Return value

Actual value from registry key, if it's exists. ADefault value - if there is error (no access, value or key do not exist).

 

Returned value does not need to be decoded by DecodeConfigValue, because registry can hold exact binary copy of data itself.

 

Remarks

 

Warning

This is low-level routine. Use it only to implement your own custom high-level wrapper.

 

Use ConfigReadString or ConfigWriteString (or their equivalents) to read and write configurations.
