Detailed Description

Represents an internal object used to read or write registry values.

The RegistryKey::accessor class SHOULD NOT be used explicitly. The only correct usage is when such temporary object is returned from RegistryKey::operator[]().

In that case optimizer prevents the object from being physically stored in stack. Instead, the key and value name pointers are directly passed to corresponding functions.

To see how it works, you should compile the SAMPLES\WINDOWS\REGISTRY sample program in Release configuration, and disassemble it.

All methods/operators are divided into the following groups:

• Strong-typed query methods allow reading value using key[idx].ReadValue(&val) syntax. The main idea for them is to support strong typing, for example, distinguish between LONGLONG and ULONGLONG.
• Simple query operators allow reading the value as val = key[idx]
• Simple set operators for writing using simple syntax as key[idx] = val
• Strong-typed set methods allow distinguishing between some similar types, such as LONGLONG and ULONGLONG.
• Additional methods, such as SetValueEx()/QueryValueEx()
