The CStaticFilespec control is a lightweight class suitable for displaying long filespecs
that may need to be truncated or compressed, in order to fit the size of the display.
Here's and example of what the control looks like when used in a dialog box.

<p>

<p>

By default, CStaticFilespec supports 2 drawing styles: <tt>DT_END_ELLIPSIS</tt> and
<tt>DT_PATH_ELLIPSIS</tt>.  The former displays a truncated filespec with trailing
ellipses while the latter adds embedded ellipses to a compressed filespec.

<p>
Using CStaticFilespec in a dialog is quite simple:
<ol>
  <li>  Include <tt>CStaticFilespec.h</tt> in your dialog class' header file.
        <p>

  <li>  Add member variables of type <tt>CStaticFilespec</tt> for every static text
        control you want to subclass.
        <p>

  <li>  Subclass the static text controls in your dialog's <tt>OnInitDialog()</tt> method
        and set the controls' style.
        <p>
        <tt><font color="#990000">
        &nbsp;&nbsp;m_wndStaticFileEnd.SubclassDlgItem (IDC_FILE_END, this);<br>
        &nbsp;&nbsp;m_wndStaticFilePath.SubclassDlgItem (IDC_FILE_PATH, this);<br>
        &nbsp;&nbsp;m_wndStaticFilePath.SetPath (TRUE);
        </font></tt>
        <p>
</ol>

<p>
You can also use any other <tt>DT_</tt> drawing style you like.  For example, to draw right
justified text that is vertically centered and has trailing ellipses, do:
<p>
<tt><font color="#990000">
<pre>
&nbsp;&nbsp;m_wndStaticText.SubclassDlgItem (IDC_STATIC_TEXT, this);
&nbsp;&nbsp;m_wndStaticText.SetFormat (DT_RIGHT | DT_VCENTER);
&nbsp;&nbsp;m_wndStaticText.SetWindowText ("d:\\There\\Is\\Always\\One\\More\\Bug.cpp");
</pre>
</font></tt>
