Could anyone give me some directions as how to use these two functions
using an example or pointing me to a referecnce book?  I have all the
technical library books for development PM, though it has huge amount
of info, but not very helpful in guiding me...

I was trying to filter the events passed to a list box inside a modal
dialog box (LN_SELECT).  It looked like that I was able to set up all the 
functions correctly.  But my problem came inside MsgFilterHook function because
I don't know how to make use of its PQMSG parameter!  Sometimes the hwnd
parameter in this pQmsg was set to a negative number, is it possible?  
BTW, the declaration of the MsgFilterFunction was: (used for a dialog box)

     BOOL MsgFilterHook(HAB hab, PQMSG pQmsg, USHORT uContext);

Any pointers are much appreciated!
