<h1 class="topictitle1">IA4HierarchyFolder::BindToList</h1>
<div><p><strong>Purpose</strong></p>
<p>Returns an instance of IA4HierarchyFolder that corresponds to a particular
folder in the iSeries™ Navigator
hierarchy. This is a required member function.</p>
<p><strong>Syntax</strong> </p>
<pre>HRESULT STDMETHODCALLTYPE BindToList(
HWND hwnd,
LPCITEMIDLIST pidl,
REFIID riid,
LPVOID* ppvOut
);</pre>
<p><strong>Parameters</strong></p>
<dl><dt class="dlterm">hwnd</dt>
<dd>Handle of the view window that will display the list which may be either
a tree or list control. A component should use this handle to determine if
a list of objects for this view is already cached on the client.</dd>
<dt class="dlterm">pidl</dt>
<dd>Pointer to an ITEMIDLIST (item identifier list) structure that uniquely
identifies the folder to be enumerated.</dd>
<dt class="dlterm">riid</dt>
<dd>Identifier of the interface to return. This parameter points to the IID_IA4HierarchyFolder
interface identifier.</dd>
<dt class="dlterm">ppvOut</dt>
<dd>Address that receives the interface pointer. If an error occurs, a NULL
pointer should be returned at this address.</dd>
</dl>
<p><strong>Return Codes</strong></p>
<p>Returns NOERROR if successful or E_FAIL if a general error occurred.</p>
<p><strong>Comments</strong></p>
<p>If an instance of IA4HierarchyFolder already exists for the specified folder,
then this member function should return the cached instance instead of instantiating
and initializing a separate instance. However, if the window handle associated
with the cached object is not the same as the value specified on the hwnd
parameter, then a new instance should be created.</p>
<p>The function should initialize implementation class member variables from
the parameters supplied.</p>
