CHistoryEdit is a CEdit derived control that lets you to display a scrolling
text history, much like Dev Studio's "Output" window during a compilation.
Here's an example of the control (the "History" window) being used in a dialog box.

<p>

<p>

CHistoryEdit's <tt><font color="#880000">AppendString()</font></tt> method appends a text
string to the control and automatically scroll the most recent entry into view.  Two other
methods, <tt><font color="#880000">AllowSelection()</font></tt> and
<tt><font color="#880000">IsSelectable()</font></tt> allow you to control whether the user
may select text in the control.

<p>
Using CHistoryEdit in a dialog is quite simple:

<ol>
  <li>  Include <tt>CHistoryEdit.h</tt> in your dialog class' header file.
        <p>
  <li>  Add member variables of type <tt>CHistoryEdit</tt> for every edit control
        you want to subclass.
        <p>
  <li>  Subclass the edit controls in your dialog's <tt>OnInitDialog()</tt> method.
        <p>
        <tt><font color="#880000">
        &nbsp;&nbsp;m_HistoryEdit.SubclassDlgItem (EDIT_HISTORY, this);
        </font></tt>
        <p>
  <li>  Append text to the control by using <tt><font color="#880000">AppendString()</font></tt>.
        <p>
        <tt><font color="#880000">
        &nbsp;&nbsp;m_HistoryEdit.AppendString ("Compiling D:\\XDA\\Test\\Mechanic.kb...");
        </font></tt>
</ol>
