|
* 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
|
|
* 10/05/99 rodtoll Added DPF_MODNAMEs
|
|
* 10/07/99 rodtoll Updated to work in Unicode
|
|
* 10/08/99 rodtoll Fixes to DeleteKey / Reg/UnReg for Win9X
|

|
|
* 01/24/00 rodtoll Fixed error handling for ReadString (Unicode version)
|
|
* 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
|
|
* 05/02/00 mjn Changed CRegistry::Open() to use KEY_READ when Create set to FALSE
|
|
* 06/08/00 rmt Updated to use common string utils
|
|
* 07/06/00 rmt Modified to allow seperate read/write parameter
|
|
* 07/09/2000 rodtoll Added signature bytes
|
|
* 07/21/00 rmt Fixed a memory leak
|
|

|
|
* 08/30/2000 rodtoll Bug #171822 - PREFIX Bug
|
|
* 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.
