Hi Chaim.

>1. is this the right method to use for this purpose?

Yes.

>2. if this is the right method for this purpose, what parms should be supplied? Is cKeyName the long key that you find in the registry enclosed in curly braces ({})?

Yes. nRegKey should be HKEY_CLASSES_ROOT (a constant defined in FFC\REGISTRY.H) and cKeyName is the key under that eg. COMCTL.ImageListCtrl for the ImageList control version 5.

eg.

llFound = loRegistry.IsKey('COMCTL.ImageListCtrl', HKEY_CLASSES_ROOT)
