SOM_Scope ULONG SOMLINK MyObj_wpAddSystem256ColorPage(MyObj somSelf,
HWND hwndNotebook)
{
/ MyObjData *somThis = MyObjGetData(somSelf); */
MyObjMethodDebug("MyObj","MyObj_wpAddSystem256ColorPage");
/* return (parent_wpAddSystem256ColorPage(somSelf,hwndNotebook)); */
return ( SETTINGS_PAGE_REMOVED );
}
