-------------------------------------------------------------------------------
The information in this article applies to:

- The Microsoft Active Template Library (ATL) 3.0, used with:
   - Microsoft Visual C++, 32-bit Enterprise Edition, version 6.0 
   - Microsoft Visual C++, 32-bit Professional Edition, version 6.0 
   - Microsoft Visual C++, 32-bit Learning Edition, version 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

The DECLARE_REGISTRY() macro in ATL allows you to pass a string resource ID,
which serves as a description and is supposed to be added to the registry as
default values for the following keys:

HKCR\<ProgID>
HKCR\<Version Independent ProgID>
HKCR\CLSID\<CLSID>

In ATL 3.0, the string is not added to the registry.

CAUSE
=====

CComModule::RegisterProgID() and CComModule::RegisterClassHelper() are used with
the DECLARE_REGISTRY() macro. Both functions create registry keys with only the
KEY_READ flag, allowing only read access.

RESOLUTION
==========

Modify CComModule::RegisterProgID() and CComModule::RegisterClassHelper() so
that the calls to CRegKey::Create() take KEY_READ|KEY_WRITE instead of just
KEY_READ. Modify the following lines from:

  // line 4909 in ATLBASE.H in CComModule::RegisterProgID()
  LONG lRes = keyProgID.Create(HKEY_CLASSES_ROOT, lpszProgID, REG_NONE, REG_OPTION_NON_VOLATILE, KEY_READ);

and

  // line 5033 in ATLBASE.H in CComModule::RegisterClassHelper()
  lRes = key.Create(key, lpsz, REG_NONE, REG_OPTION_NON_VOLATILE, KEY_READ);

to

  LONG lRes = keyProgID.Create(HKEY_CLASSES_ROOT, lpszProgID, REG_NONE, REG_OPTION_NON_VOLATILE, KEY_READ|KEY_WRITE);

and

  lRes = key.Create(key, lpsz, REG_NONE, REG_OPTION_NON_VOLATILE, KEY_READ|KEY_WRITE);

STATUS
