[	Anybody willing to send me (or post) one of their custom controls?
	A comlete example would be really useful.	]

Either way, can anyone answer these two questions?

1.  Handling a WM_SETTEXT should set the control's text pointer
to (LPSTR)lParam.  Looking at DefWindowProc included in the SDK, they
do a call to DefSetText which I assume does this.  WM_GETTEXT returns
a copy of hwnd->hName.  My question is, how does my custom control
get access (read and write) to hName, the control's text pointer?

2.  General question:  Is there some way I can use subclassing to 
trap messages of normal controls?  In other words, can I create a new
class and end it with a CallWindowProc to a standard class' window proc?
(Example:  Create a windowclass with a cross cursor, check for WM_RBUTTONDOWN,
and otherwise handle everything as if it were a "static" control).  I've
tried several times, but keep getting unrecov app errs.

thanks,
