<font face="Arial,Helvetica"><font size=+0>Analysis:</font></font></h3>
<font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>Let's
analyze this first example.</font></font></font>
<br><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>This
example shows how to register a dialog template as a window class and create
a "window" from that class. It simplifies your program since you don't
have to create the child window controls yourself.</font></font></font>
<br><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>Let's
first analyze the dialog template.</font></font></font>
<p><b><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>MyDialog
DIALOG 10, 10, 205, 60</font></font></font></b>
<p><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>Declare
the name of a dialog, in this case, "MyDialog" followed by the keyword
"DIALOG". The following four numbers are: x, y , width, and height of the
dialog box in dialog box units (not the same as pixels).</font></font></font>
<p><b><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>STYLE
0x0004 | DS_CENTER | WS_CAPTION | WS_MINIMIZEBOX |</font></font></font></b>
<br><b><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>WS_SYSMENU
| WS_VISIBLE | WS_OVERLAPPED | DS_MODALFRAME | DS_3DLOOK</font></font></font></b>
<p><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>Declare
the styles of the dialog box.</font></font></font>
<p><b><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>CAPTION
"Our First Dialog Box"</font></font></font></b>
<p><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>This
is the text that will appear in the dialog box's title bar.</font></font></font>
<p><b><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>CLASS
"DLGCLASS"</font></font></font></b>
<p><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>This
line is crucial. It's this <b>CLASS</b> keyword that allows us to use the
dialog box template as a window class. Following the keyword is the name
of the "window class"</font></font></font>
<p><b><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>BEGIN</font></font></font></b>
<br><b><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>&nbsp;&nbsp;&nbsp;

<br><b><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>&nbsp;&nbsp;&nbsp;

<br><b><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>END</font></font></font></b>
<p><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>The
above block defines the child window controls in the dialog box. They're
defined between <b>BEGIN</b> and <b>END</b> keywords. Generally the syntax
is as follows:</font></font></font>
<ul><b><font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>control-type&nbsp;
"text"&nbsp;&nbsp; ,controlID, x, y, width, height [,styles]</font></font></font></b></ul>
<font face="Arial,Helvetica"><font color="#CCCCCC"><font size=-1>control-types
are resource compiler's constants so you have to consult the manual.</font></font></font>

we go to the assembly source code. The interesting part is in the window
