<h1 class="topictitle1">IA4HierarchyFolder::ItemAt</h1>
<div><p><strong>Purpose</strong></p>
<p>Returns as SHITEMID (item identifier) structure for the folder object at
the specified position in the list of folder contents. This is a required
member function.</p>
<p><strong>Syntax</strong></p>
<pre>HRESULT STDMETHODCALLTYPE ItemAt(
ULONG ulIndex,
LPITEMIDLIST* ppidl
); </pre>
<p><strong>Parameters</strong></p>
<dl><dt class="dlterm">ulIndex</dt>
<dd>The zero-based index of the item for which an item identifier is requested.</dd>
<dt class="dlterm">ppidl</dt>
<dd>Address of the pointer that will receive the requested item identifier.</dd>
</dl>
<p><strong>Return Codes</strong></p>
<p>Returns NOERROR if successful or E_FAIL if the item is not available. Returns
E_OUTOFMEMORY if insufficient memory was available for the item identifier.</p>
<p><strong>Comments</strong></p>
<p>The iSeries™ Navigator
repeatedly calls this function to populate a folder in realtime. Long running
operations should therefore be avoided. Refer to CWBA4HYF.H for the format
of iSeries Navigator
item identifiers. Use the Windows<sup>®</sup> IMalloc interface to allocate
memory for the item identifier.</p>
