RegistryProxy.DynData Property

Note: This API is now obsolete.

Returns a RegistryKey type, which provides access to HKEY_DYNDATA.

Namespace:  Microsoft.VisualBasic.MyServices
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

[ObsoleteAttribute("The DynData registry key works only on Win9x, which is not supported by this version of the .NET Framework.  Use the PerformanceData registry key instead.  This property will be removed from a future version of the framework.")]
public RegistryKey DynData { get; }

HKEY_DYNDATA is used to store dynamic registry data, such as that used by Virtual Device Drivers and is supported only on Windows 95/98 systems. On non-Windows 95/98 systems, calling any methods of the key returned by Registry.DynData, such as CreateSubKey, DeleteSubKey, GetSubKeyCount, GetValueCount, etc., will throw a IOException.

The RegistryPermission class, which is in the System.Security.Permissions namespace, controls access to registry variables. Registry variables should not be stored in memory locations where code without RegistryPermission can access them. Similarly, when granting permissions, grant the fewest privileges necessary to get the job done.

Registry permission access values are defined by the RegistryPermissionAccess enumeration. The following table details its members.
