IADsContainer::GetObject method (iads.h)

The IADsContainer::GetObject method retrieves an interface for a directory object in the container.

Syntax

HRESULT GetObject(
  [in]  BSTR      ClassName,
  [in]  BSTR      RelativeName,
  [out] IDispatch **ppObject
);

Parameters

[in] ClassName

A BSTR that specifies the name of the object class as of the object to retrieve. If this parameter is NULL, the provider returns the first item found in the container.

[in] RelativeName

A BSTR that specifies the relative distinguished name of the object to retrieve.

[out] ppObject

A pointer to a pointer to the IDispatch interface on the specified object.

Return value

This method supports standard return values, including S_OK for a successful operation. For more information about error codes, see ADSI Error Codes.

Remarks

For the LDAP provider, the bstrRelativeName parameter must contain the name prefix, such as "CN=Jeff Smith". The bstrRelativeName parameter can also contain more than one level of name, such as "CN=Jeff Smith,OU=Sales".

In C++, when GetObject has succeeded, the caller must query the IDispatch interface for the desired interface using the QueryInterface method.

The bstrClassName parameter can be either a valid class name or NULL. If the class name is not valid, including when it contains a blank space, this method will throw an E_ADS_UNKNOWN_OBJECT error.

Examples

The following code example retrieves a user object from a container object.

Dim cont As IADsContainer
Dim usr As IADsUser
Set cont = GetObject("LDAP://OU=Sales,DC=Fabrikam,DC=com")
Set usr = cont.GetObject("user", "CN=jeffsmith")

This is equivalent to:

Dim usr As IADsUser
Set usr=GetObject("LDAP://CN=jeffsmith,OU=Sales,DC=Fabrikam,DC=com")

The following code example retrieves a user object from a container object.

HRESULT hr = S_OK;
CoInitialize(NULL);
 
IADsContainer *pCont = NULL;
 
hr = ADsGetObject(L"LDAP://DC=windows2000,DC=mytest,DC=fabrikam,DC=com",
            IID_IADsContainer, 
            (void**) &pCont );

if(FAILED(hr))
{
    goto Cleanup;
}

if(FAILED(hr))
{
    goto Cleanup;
}
 
hr = pDisp->QueryInterface(IID_IADs, (void**)&pADs);
pDisp->Release(); 
if(FAILED(hr))
{
    goto Cleanup;
}
 
// Perform an operation with pADs.
pADs->Release();
 
Cleanup:
if(pCont)
    pCont->Release();

if(pDisp)
    pDisp->Release();

if(pADs)
    pADs->Release();

CoUninitialize();
