??? ?????? ????????? 32-??? ????????? ?? ????? ????????? ?????? ?? ????? ?? ?????? ???????? ????? ?? ??? ?????? ???? ?? ??? ?? ?? ???? ??? ?? ?????? ??? ??? discussed, ???? 16-??? RegSetValue ?? RegQueryValue ?? ??? ???? ??? ??????? ????? (???? REG_SZ ?????? ?? ????? ??) ?? ??????? ?? ???? These functions appear in the 32-bit Registry Editor with a name of <no name="">. To set, modify, or query this special associated value, one must use the 16-bit registry functions. Reading and writing from the registry in a 16-bit environment is much simpler than in a 32-bit environment. The same basic procedure is followed: open a key and get a handle and then call your modification function with that handle, but no consideration needs to be made for multiple associated values or for different value data types. A 16-bit application can create and modify keys and values with the declarations of the RegCreateKey, RegOpenKey, RegQueryValue, RegSetValue, and RegCloseKey functions. </no>

In some cases, there is no need for any values to be associated with a key. An application may only need to know if a certain key or value exists, and not care about the nature of the key's values. In a situation like this, the RegEnumKey, RegEnumKeyEx, and RegEnumValue functions can be used to determine whether a certain key or value exists. For more information on these functions refer to the API Text Viewer and/or Windows API reference.
