memory leaks when the program exits. </span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-AU style='font-size:

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-AU style='font-size:
10.0pt;font-family:Arial'>The cause of these memory leaks relates to using the MFC
library as a shared DLL. So to avoid memory leaks you must use the MFC library
as a statically linked library. However, the MCF App Wizard, by default, selects
using the library as a shared DLL, so when creating a project make sure to click
on the “As a statically linked library” radio button in the IDE. When
building an SDI or a MDI application this is Step 5 in the MFC App Wizard and for
a Dialog application, this is Step 3.</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-AU style='font-size:

libraries so we <b><u><span style='font-weight:bold'>should</span></u></b> be
using the MFC library as a statically linked library!</span></font></p>
