* History:
* Date By Reason
* ==== == ======
* 07/16/99 rodtoll Created
* 08/18/99 rodtoll Added Register/UnRegister that can be used to
* allow COM objects to register themselves.
* 08/25/99 rodtoll Updated to provide read/write of binary (blob) data
* 10/07/99 rodtoll Updated to work in Unicode
* 10/27/99 pnewson added Open() call that takes a GUID
* 01/18/00 mjn Added GetMaxKeyLen function
* 01/24/00 mjn Added GetValueSize function
* 04/05/2000 jtk Changed GetVauleSize to GetValueLength and modified to return WCHAR lengths
* 04/21/2000 rodtoll Bug #32889 - Does not run on Win2k on non-admin account
* rodtoll Bug #32952 - Does not run on Win95 GOLD w/o IE4 -- modified
* to allow reads of REG_BINARY when expecting REG_DWORD
* 07/09/2000 rodtoll Added signature bytes
* 08/28/2000 masonb Voice Merge: Modified platform checks to use osind.cpp layer (removed CRegistry::CheckUnicodePlatform)
* 04/13/2001 VanceO Moved granting registry permissions into common, and
* added DeleteValue and EnumValues.
* 06/19/2001 RichGr DX8.0 added special security rights for "everyone" - remove them if
* they exist with new RemoveAllAccessSecurityPermissions() method.
