WinCE 6.0: Customizing Control Panel (cplmain)

i work on a Windows CE 6.0 Image and added a Audio driver to my Solution (my solution is based on a image without audio). Sound works fine but i dont know how i can add the standard Windows CE 6.0 Sound Settings dialog to the control panel.

MSDN says the following: "The Windows CE Control Panel allows users to set a variety of system-wide properties, such as mouse sensitivity, network setup, and the desktop color scheme. You can select specific functionality to include in your Control Panel by specifying them in your Cesysgen.bat file." Can anyone explain how this works exactly via Cesysgen.bat? In my project i cant find any entry for cplmain in my Cesysgen.bat.

Could it be that those standard Applets are integrated into the control panel automatically? (maybe with "getProcAddress()" when a specific driver is loaded?) - This idea comes from "cplmain.def", there is written:

EXPORTS
    CPlApplet

    ; These functions are exported for componentization
    ; We use GetProcAddress on ourselves to dynamically discover 
    ; what components we have

I found a quite good explanation from Andrew Pearson here: http://www.itlisting.org/4-windows-ce-embedded/a57eef4103191b7a.aspx but i tried a few different things an nothing worked! So this confuses me even more. The only statement there i really understand now is:

The control panel, unfortunately, is about the single most confusing thing 
to build in the whole tree.

Yes it is! Would be nice if anyone had an idea.

Kind regards, Martin

I've created custom control panel applets before, and to be honest, trying to modify the existing applet is about the worst thing you can try. Generally what I do is just create a whole new applet, which is really just a DLL renamed to have a .cpl extension and that exports the CPlApplet entry point.

There's an example in MSDN that shows the expected values the OS will pass in to get your icon, tell you to start and those types of things.

Basically just build your own applet as a completely separate project, then include it in the MODULES section of your BIB file. Don't even mess with the existing train wreck of control panel code.
