 <a href="text_progressctrl.shtml#latest">26th May 1998</a></p>

<p>This is a simple CProgressCtrl derived class that allows text
to be displayed on top of the progress bar in much the same way
as many &quot;Setup&quot; programs display the progress of long
operations. </p>

<p>The control is extremely simple and allows the same operations
as a standard CProgressCtrl, as well as: </p>

<pre><font color="#990000"><tt>	void SetShowText(BOOL bShow);
</tt></font></pre>

<p>which determines whether or not the text for the control will
be displayed during updates. To set the text to be displayed use
the standard <font color="#990000"><tt>CWnd::SetWindowText</tt></font>.
If you call <font color="#990000"><tt>SetShowText(TRUE)</tt></font>
but do not specify any window text using <font color="#990000"><tt>CWnd::SetWindowText</tt></font>,
then the percentage fraction of progress will be displayed as
default. </p>

<p>To use the control, just include a CProgressCtrl in your app
as per usual (either dynamically or by using a dialog template)
and change the variable type from CProgressCtrl to
CTextProgressCtrl. (Make sure you include TextProgressCtrl.h) </p>

<p>At present the progress is only displayed as a smooth bar.
(This may be changed in the future versions.) </p>
