IADsAccessControlList::get__NewEnum

The IADsAccessControlList::get__NewEnum method is used to obtain an enumerator object for the ACL to enumerate ACEs.

HRESULT get__NewEnum(
  IUnknown ** ppEnumerator 
);

Parameters

ppEnumerator

[out] Pointer to the IUnknown interface used to query the IEnumVARIANT interface on an enumerator object for the ACL.

Return Values

This method returns the standard return values, including S_OK and E_FAIL. For other return values, see ADSI Error Codes.

Remarks

Notice that there are two underscores in get__NewEnum.

Example Code [Visual Basic]

Visual Basic® makes an implicit call to the get__NewEnum method in the execution of the For Each obj In collection … Next obj statement.

Dim Dacl As IADsAccessControlList
Dim ace as IADsAccessControlEntry

' Do something to get Dacl, code omitted.

' Remove all the ace's from the acl.
For Each ace In Dacl 
    Dacl.RemoveAce (ace) 
Next ace

Example Code [C++]

C/C++ code will be more involved. The following C++ code snippet illustrates how to enumerate ACEs using IADsAccessControlList::get__NewEnum.

IEnumVARIANT *pEnum;
LPUNKNOWN     pUnk;
ULONG  lFetch;
BSTR    bstr;
IADsAccessControlEntry *pACE;
 
hr = pACL->get__NewEnum( &pUnk );
if ( !SUCCEEDED(hr) )
{
   pACL->Release();
   return;
}
 
hr = pUnk->QueryInterface( IID_IEnumVARIANT, (void**) &pEnum );
if ( !SUCCEEDED(hr) )
{
   return;
}
 
hr = pEnum->Next( 1, &var, &lFetch );
 
while( hr == S_OK )
{
   if ( lFetch == 1 )
   {
       if ( VT_DISPATCH != V_VT(&var) )
       {
           pEnum->Release();
           return;
       }
       pDisp = V_DISPATCH(&var);
       /////////////////////////
       // Get the individual ACE
       /////////////////////////
       hr = pDisp->QueryInterface( IID_IADsAccessControlEntry,
                                  (void**)&pACE ); 
      if ( SUCCEEDED(hr) )
      {
          pACE->get_Trustee(&bstr);
          printf("\n %S:\n", bstr);
          //ACE manipulation here
          SysFreeString(bstr);
          pACE->Release();
      }
      VariantClear(&var);
   }
hr = pEnum->Next( 1, &var, &lFetch );
};
