FIX: Descriptions Aren't Added to Registry When Using DECLARE_REGISTRY() Macro

ID: Q217182

The information in this article applies to:

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);
