<h1 class="topictitle1">IA4HierarchyFolder::GetColumnDataItem</h1>
|

|
|
<div><p><strong>Purpose</strong></p>
|
||
|
|
<p>Returns a data field for a folder or object to be displayed in a column
|
||
|
|
in the list view of the iSeries™ Navigator. This is a required member function.</p>
|
||
|
|
<p><strong>Syntax</strong></p>
|
||
|
|
<pre>HRESULT STDMETHODCALLTYPE GetColumnDataItem(
|
||
|
|
LPCITEMIDLIST pidl,
|
||
|
|
LPARAM lParam,
|
||
|
|
char * lpszColumnData,
|
||
|
|
UINT cchMax
|
||
|
|
);</pre>
|
||
|
|
<p><strong>Parameters</strong></p>
|
||
|
|
<dl><dt class="dlterm">pidl</dt>
|
||
|
|
<dd>Pointer to an ITEMIDLIST (item identifier list) structure that uniquely
|
||
|
|
identifies the object whose column data is to be obtained.</dd>
|
||
|
|
<dt class="dlterm">lParam</dt>
|
||
|
|
<dd>The value that was previously associated with the column for which data
|
||
|
|
is requested by the component (see GetColumnInfo).</dd>
|
||
|
|
<dt class="dlterm">lpszColumnData</dt>
|
||
|
|
<dd>Address of the buffer that will receive the null-terminated data string.</dd>
|
||
|
|
<dt class="dlterm">cchMax</dt>
|
||
|
|
<dd>Size of the buffer that will receive the null-terminated data string.</dd>
|
||
|
|
</dl>
|
||
|
|
<p><strong>Return Codes</strong></p>
|
||
|
|
<p>Returns NOERROR if successful or an E_FAIL if unable to retrieve the column
|
||
|
|
data.</p>
|
||
|
|
<p><strong>Comments</strong></p>
|
||
|
|
<p>This function is called repeatedly by the iSeries Navigator when populating a list
|
||
|
|
view. Long running operations should therefore be avoided.</p>
