RegistryHelper

This project provides a RegistryHelper class for accessing the Windows Registry using Modern C++

Project Structure

RegistryHelper

RegistryHelper is a convenient utility encapsulated in a single header file named RegistryHelper.hpp. This header file provides common operations for interacting with the Windows registry.

RegistryInterface

RegistryInterface is a work-in-progress module that already contains predefined operations such as:

• GetAutoRebootSetting
• EnumerateServices ...

The RegistryInterface is continuously evolving, and additional functionalities will be added over time. The purpose of this module is to encapsulate and provide an organized set of registry-related operations for ease of use.

Usage

Using as a Library

Include the "RegistryHelper.hpp" header file in your project.
Link your project with the compiled "RegistryHelper.lib" library.

.lib files as linker input

Walkthrough: Create and use a static library

Using Directly

Include the "RegistryHelper.h" header file in your source files.

Example Usage

#include "RegistryHelper.h"

// Create an instance of RegistryHelper
RegistryHelper registryHelper;

// Example 1: Reading DWORD value (REG_DWORD)
std::wstring valueNameDword = L"BootDriverFlags";
DWORD dwordValue = registryHelper.RegGetDword(hKey, subKey, valueNameDword);

// Example 2: Reading String value (REG_SZ)
std::wstring valueNameString = L"CurrentUser";
std::wstring stringValue =
  registryHelper.RegGetString(hKey, subKey, valueNameString);

// Example 3: Reading Multi-String value (REG_MULTI_SZ)
std::wstring valueNameMultiString = L"PreshutdownOrder";
std::vector<std::wstring> multiStringValue =
  registryHelper.RegGetMultiString(hKey, subKey, valueNameMultiString);

// Example 4: Enumerate sub-keys
std::vector<std::pair<std::wstring, DWORD>> subKeys =
  registryHelper.RegEnumSubKeys(hKey, subKey);

// Example 5: Enumerate values
std::vector<std::pair<std::wstring, DWORD>> values =
  registryHelper.RegEnumValues(hKey, subKey);


// Set DWORD value under a non-existing key (will create the key first)
registryHelper.RegSetDword(HKEY_LOCAL_MACHINE,
                           L"SOFTWARE\\NewApp",
                           L"NewDWORD",
                           123);

Adjust the registry keys, subkeys, and value names based on your specific use case.
