/*
* General rules for being installed in the Control Panel:
*
* 1) The DLL must export a function named CPlApplet which will handle
* the messages discussed below.
* 2) If the applet needs to save information in CONTROL.INI minimize
* clutter by using the application name [MMCPL.appletname].
* 2) If the applet is refrenced in CONTROL.INI under [MMCPL] use
* the following form:
* ...
* [MMCPL]
* uniqueName=c:\mydir\myapplet.dll
* ...
*
*
* The order applet DLL's are loaded by CONTROL.EXE is not guaranteed.
* Control panels may be sorted for display, etc.

// cache. Once the resource information is in the cache, the system does not
// need to load a CPL unless the user actually tries to use it.

// load the CPL every time it needs to display information about an item. This
// allows a CPL to dynamically decide what information will be displayed, but
// is SIGNIFICANTLY SLOWER than displaying information from a cache.
// Typically, CPL_DYNAMIC_RES is used when a control panel must inspect the
// runtime status of some device in order to provide text or icons to display.
