; Message validation layer include file
;
;- Where applicable, i've specified a class id. as a param. to the MESSAGE
;  macro. For others (WM_ messages), i've specified the ID "COMMON".
;
;- For messages meaningful only to controls having a particular style, i've
;  added an option to the MESSAGE macro:
;
;  <MLCONLY>	     for messages applicable to ES_MULTILINE edit controls
;  <OWNERDRAWVARONLY> "     "	      "       " LBS_OWNERDRAWVARIABLE listboxes
;  <MULTISELONLY>     "     "	      "       " LBS_MULTIPLESEL listboxes
;  <MULTICOLONLY>     "     "	      "       " LBS_MULTICOLUMN listboxes
