identifier "PLVGROUP" is undefined afxcmn.h
<p>I have a Visual Studio 2015 project which uses the afxcmn header and is having a lot of "is undefined" errors.</p>

<p>I read in the documentation those data types are included in commctrl.h which is already included in the Visual Studio project as external dependency.</p>

<pre><code>// Adds a group to the control.
AFX_ANSI_DEPRECATED int InsertGroup(_In_ int index, _In_ PLVGROUP pgrp);

// Sets information about the specified group (by ID) in the control.
AFX_ANSI_DEPRECATED int SetGroupInfo(_In_ int iGroupId, _In_ PLVGROUP pGroup);

// Retrieves information for the specified group in the control.
AFX_ANSI_DEPRECATED int GetGroupInfo(_In_ int iGroupId, _Out_ PLVGROUP pgrp) const;
</code></pre>

<p>That is some code example of the afxcmn.h which gives those errors.</p>

<p>I dont know if I have to configure something else in the project to include the commctrl header</p>
