ADEX Registry is a COM component that enables application developers of Microsoft technology to access the system registry from their application code. ADEX Registry has been developed using Microsoft ATL, providing users fast access to the registry. It provides an intuitive Object Model with a design similar to the system registry's structure, giving users access to any key/value/data they want. If users are not familiar with the registry structure and just want to read/write data from/to it, they may simply call the GetAppData/SetAppData.
