Members

Member name Description

ClassesRoot Represents the HKEY_CLASSES_ROOT base key on another computer. This value can be passed to the OpenRemoteBaseKey method, to open this node remotely.

CurrentConfig Represents the HKEY_CURRENT_CONFIG base key on another computer. This value can be passed to the OpenRemoteBaseKey method, to open this node remotely.

CurrentUser Represents the HKEY_CURRENT_USER base key on another computer. This value can be passed to the OpenRemoteBaseKey method, to open this node remotely.

DynData Represents the HKEY_DYN_DATA base key on another computer. This value can be passed to the OpenRemoteBaseKey method, to open this node remotely.

LocalMachine Represents the HKEY_LOCAL_MACHINE base key on another computer. This value can be passed to the OpenRemoteBaseKey method, to open this node remotely.

PerformanceData Represents the HKEY_PERFORMANCE_DATA base key on another computer. This value can be passed to the OpenRemoteBaseKey method, to open this node remotely.

Users Represents the HKEY_USERS base key on another computer. This value can be passed to the OpenRemoteBaseKey method, to open this node remotely.

Remarks

RegistryHive values are used by the OpenRemoteBaseKey method to represent the top-level node of a requested key on a foreign (remote) machine. The node that can be opened with the OpenRemoteBaseKey method must be one of these top-level RegistryKeys. Further access to the subkeys of the identified node is available using using methods in RegistryKey, so long as the the user has appropriate permission.

Example

The following code example shows how to open a registry key on a remote computer and enumerate the values of the key. The remote computer must be running the remote registry service. Specify the name of the remote computer as a command-line argument when invoking the program.
