<!-- The article... -->

<p>I got this masked edit control code from someone (I can't remember whom
it was). If anyone wishes to lay claim to the original they are more than welcome.
I have found this quite useful. So I can't lay claim to doing all or even most of this.
However I have enhanced the code to deal with times as well as dates.

<p>I have also added validation of the keystrokes so that invalid times i.e. &gt;
23:59 are not allowed. (I have limited the time validation to minutes. It would be no 
great effort to add in the seconds. Validation for dates is a little more difficult. 
Validation is limited to months &lt; 13 and days &lt; 32.

<p>i.e you can put in 31/02/1998 for example.

<p>Ok how to make it work. There are three classes

<ul>
<li>CMaskEdit
<li>CDateEdit
<li>CTimeEdit
</ul>

<p>Include the two files MASKED.CPP and MASKED.H in your project.
Also include &lt;afxdao.h&gt; for the COleDateTime features if you already
haven't. Modify the include line that says #include "myproj" to point to your
project. Create a CEdit control and declare a control variable in your dialog
then modify the CEdit declaration in the class header to say either
CDateEdit or CTimeEdit

<h4>CDateEdit:</h4>

<p>Pass your time to CDateEdit with

<FONT COLOR="#990000"><TT><PRE>	CDateEdit myeditctrl;
	myeditctrl.SetDate(COleDateTime var);
</tt></PRE></FONT>

<p>and get the edited result back with

<FONT COLOR="#990000"><TT><PRE>	COleDateTime var = myeditctrl.GetDate();
</tt></PRE></FONT>

<h4>CTimeEdit:</h4>

<p>Pass your time to CTimeEdit with

<FONT COLOR="#990000"><TT><PRE>	CTimeEdit myeditctrl;
	myeditctrl.SetTime(COleDateTime var);
</tt></PRE></FONT>

<p>and get the edited result back with

<FONT COLOR="#990000"><TT><PRE>	COleDateTime var = myeditctrl.GetTime();
</tt></PRE></FONT>

<p>and there you have it.

<p>Please feel free to modify any modifications I have made. These are stated
with //added this
