<p>the original source for this code came from <a href="mailto::sam.claret@dial.pipex.com">sam

<p><strong>ctimeedit</strong><br>
the class that i was originally interested in was his ctimeedit that allowed the editing
of hours and minutes in an edit control. his original code only allowed a maximum 23<sup>rd</sup>
hour, and 59<sup>th</sup> minute, i.e. the standard 24 hour clock. there was no way of
specifying a 12 hour clock or even a 48 hour clock.. for this reason i have added <tt><font
color="#990000">sethours(int hrs)</font></tt>, <tt><font color="#990000">setmins(int mins)</font></tt>to
ctimeedit to allow this, and <tt><font color="#990000">settime(cstring date)</font></tt>,
and <tt><font color="#990000">cstring gettimestr()</font></tt> to extend the use with
other time functions..</p>
<p>as with sam's code... </p>
<pre><font color="#990000"><tt> #include <afxdao.h>
</pre>
</tt></font>
<p>in a header file such as stdafx.h. then create a cedit box in the dialog editor, and
using classwizard declare a cedit control variable for it such as m_editctrl.next edit the
relevant header file to change the control variable from cedit to ctimeedit. </p>
<p>in a fuction such as oninitdialog either write... </p>
<pre><font color="#990000"><tt> m_editctrl.settime(coledatetime::getcurrenttime());
</pre>
</tt></font>
<p>or </p>
<pre><font color="#990000"><tt> m_editctrl.settime("11:03");
</pre>
</tt></font>
<p>to set the time and then to set the maximum hours and minutes write... </p>
<pre><font color="#990000"><tt> m_editctrl.sethours(12);
m_editctrl.setmins(59);
</pre>
</tt></font>
<p>to return the time in a string rather than a coledatetime object write... </p>
<pre><font color="#990000"><tt> cstring string = m_editctrl.gettimestr();</tt></font></pre>
<p>the default maximum hours are 24, and the default maximum minutes are 59. </p>
<p> </p>
<p><strong>cmaskedit<br>
</strong>joe ismert asked me how he could use this masked edit class to allow entry of,
for example a telephone number. well cdateedit and ctimeedit are both sub-classes of
cmaskedit. to create your own customised masked edit control you can either create your
own sub-class of cmaskedit for your own unique mask, or use cmaskedit directly. the
following telephone number, ip address, and post code examples all use cmaskdirectly,
however can be placed a their own unique sub-class for which either cdateedit and
ctimeedit can be used as examples.</p>

<p><strong>telephone number<br>

oninitdialog write...<br>

<p><a name="updates"></a><strong>updates</strong></p>
<p><strong>12th august 1998<br>
</strong> cmaskedit : added the use of backspace to replace what has already
been typed with another string (by <a href="mailto::rfujimoto@oceania.com">rodney fujimoto</a>).
the examples use the original string as a replacement, however by default the
replacement is blank, thus nothing will be replaced by the backspace key.<br>
provided separate .zip file of masked.cpp and masked.h to demo .zip file.<br>
updated demo .exe.</p>
<p><strong>7th august 1998<br>
</strong> ctimeedit : added settime(cstring date), and cstring gettimestr().<br>
cmaskedit : cured bug with "9" masks not allowing spaces.<br>
updated article and demo .exe, added examples.</p>
<p><strong>27th july 1998<br>
</strong>original version</p>
