Some of the things that you will find in just about every Windows application are
buttons, check boxes, text fields, and drop-down list boxes. These are known as controls,
and many of these controls are built into the operating system itself. With Visual
C++, using these common controls is as easy as placing them on a dialog window with
a drag-and-drop window design method. Today you are going to learn</P>

<P>Several standard controls are built into the Windows operating system, including
such things as sliders, tree and list controls, progress bars, and so on. However,
today you will work with a half dozen controls that appear in just about every Windows
application:</P>
<UL>
<LI>Static text
<P>
<LI>Edit box
<P>
<LI>Command button
<P>
<LI>Check box
<P>
<LI>Radio button
<P>
<LI>Drop-down list box (also known as a combo box)
</UL>
<P>These and other controls are readily available for use in Visual C++ applications.
They can be found on the controls palette in the Dialog Painter editor in the Developer
Studio, as shown in Figure 2.1.</P>
