IADs Property Methods
Applies to: desktop apps only
The property methods of the IADs interface get or set the properties described in the following table. For more information about property methods, see Interface Property Methods.
Properties
- ADsPath
-
- The ADsPath string of this object. The string uniquely identifies this object in a network environment. The object can always be retrieved using this path.
- Access type: Read-only
- Scripting data type: BSTR
-
// C++ method syntax HRESULT get_ADsPath( [out] BSTR* pbstrADsPath );
- Class
-
- The name of the object Schema class.
- Access type: Read-only
- Scripting data type: BSTR
-
// C++ method syntax HRESULT get_Class( [out] BSTR* pbstrClass );
- GUID
-
- The globally unique identifier of the directory object. The IADs interface converts the GUID from an octet string, as stored on a directory server, into a string format.
- Access type: Read-only
- Scripting data type: BSTR
-
// C++ method syntax HRESULT get_GUID( [out] BSTR* pbstrGUID );
- Name
-
- The relative name of the object as named within the underlying directory service. This name distinguishes this object from its siblings.
- Access type: Read-only
- Scripting data type: BSTR
-
// C++ method syntax HRESULT get_Name( [out] BSTR* pbstrName );
- Parent
-
- The ADsPath string of the parent container. Active Directory does not permit the formation of the ADsPath of a given object by concatenating the Parent and Name properties. While this operation might work in some providers, it is not guaranteed to work for all implementations. The ADsPath is guaranteed to be valid and should always be used to retrieve an object's interface pointer.
- Access type: Read-only
- Scripting data type: BSTR
-
// C++ method syntax HRESULT get_Parent( [out] BSTR* pbstrParent );
- Schema
-
- The ADsPath string of the Schema class object of this object.
- Access type: Read-only
- Scripting data type: BSTR
-
// C++ method syntax HRESULT get_Schema( [out] BSTR* pbstrSchema );
Remarks
In Active Directory, the GUID returned from GUID is a string of hexadecimals. Use the resultant GUID to bind to the object directly.
where xxx is the value returned from the GUID property. For more information, see Using objectGUID to Bind to an Object. Be aware that if you use a GUID to bind to an object, the Name, ADsPath, and Parent property methods return values that are different from the normal values that would be returned if you used a distinguished name (DN) to bind to the same object. For example, the following table lists the values returned when using the two different binding methods to bind to the same user object.
| Bind using DN | Bind using GUID | |
|---|---|---|
| Name | CN=Jeff Smith | <GUID=c0f59dfcf507d311a99e0000f879f7c7> |
| Parent | LDAP://server/CN=Users,DC=Fabrikam,DC=com | LDAP://server |
| ADsPath | LDAP://server/CN=Jeff Smith,CN=Users,DC=Fabrikam,DC=com | LDAP://server/<GUID=c0f59dfcf507d311a99e0000f879f7c7> |
The GUID-binding technique returns values that may not be useful. For example, to bind to an object's parent to move or delete the object using the IADsContainer methods. To do this after binding to an object using a GUID, first rebind to the object using the DN and then use the second binding to retrieve the binding path for the parent object. The following code example shows how to do this.
' Bind to an object using its GUID. Set objFromGUID = GetObject("LDAP://<GUID=c0f59dfcf507d311a99e0000f879f7c7>") ' Rebind to the object using its distinguished name. Set objFromDN = GetObject("LDAP://" & objFromGUID.Get("distinguishedName")) ' Use the second binding to get the object's parent. Set parent = GetObject(objFromDN.Parent)
Windows XP: Binding with a GUID using the LDAP provider no longer returns a 'GUID ADsPath' for the Name and Parent property methods, and rebinding is not required when attempting to bind using the returned path strings. However, the ADsPath property method will still return a 'GUID ADsPath' when GUID binding is performed.
Note The WinNT provider does not support binding using the object GUID, and returns the GUID property in a slightly different string format.
Note The NDS and NWCOMPAT providers do not support binding using the object GUID.
Examples
The following code example shows how to retrieve object data using property methods of the IADs interface.
Dim x As IADs Dim parent As IADsContainer Dim cls As IADsClass Dim op As Variant On Error GoTo Cleanup Set x = GetObject("WinNT://Fabrikam/Administrator") Debug.Print "Object Name: " & x.Name Debug.Print "Object Path: " & x.ADsPath Debug.Print "Object Class: " & x.Class ' Get more data about the object schema. Set cls = GetObject(x.Schema) Debug.Print "Class Name is: " & cls.Name For Each op In cls.OptionalProperties Debug.Print "Optional Property: " & op Next op Cleanup: If (Err.Number<>0) Then MsgBox("An error has occurred. " & Err.Number) End If Set x = Nothing Set parent = Nothing Set cls = Nothing

The following code example shows how to work with the property methods of the IADs interface.
#include <stdio.h> #include <activeds.h> int main(int argc, char* argv[]) { IADs *pADs = NULL; IADsUser *pADsUser = NULL; IADsClass *pCls = NULL; CComBSTR sbstr; HRESULT hr = CoInitialize(NULL); if (hr != S_OK) { return 0; } hr=ADsGetObject(L"WinNT://Fabrikam/Administrator", IID_IADsUser, (void**) &pADsUser); if (hr != S_OK) { goto Cleanup; } hr = pADsUser->QueryInterface(IID_IADs, (void**) &pADs); if( hr !=S_OK) { goto Cleanup;} pADsUser->Release(); if( S_OK == pADs->get_Name(&sbstr) ) { printf("Object Name: %S\n",sbstr); } if( S_OK == pADs->get_ADsPath(&sbstr) ) { printf("Object path: %S\n",sbstr); } if( S_OK == pADs->get_Class(&sbstr) ) { printf("Object class: %S\n",sbstr); } hr = pADs->get_Schema(&sbstr); if ( hr != S_OK) {goto Cleanup;} hr = ADsGetObject(sbstr,IID_IADsClass, (void**)&pCls); if ( hr != S_OK) {goto Cleanup;} if( S_OK == pCls->get_Name(&sbstr) ) { printf("Class name is %S\n", sbstr); } Cleanup: if(pADs) pADs->Release(); if(pIADsUser) pADsUser->Release(); if(IADsClass) pADsClass->Release(); CoUninitialize(); if(hr==S_OK) { return 1; } else { return 0; } }
