|
* ==== == ======
|
|
* 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.
