I have not used the Janus Grid before, but have used other controls that have PEMs in Object Interfaces that are accessed via a call like:

loOLEObject = CREATEOBJECT("Janus.Something")

You have to determine what to use for "Janus.Something" in the above code. This is dependent on each Object Interface. Look in your Registry in the HKEY_CLASSES_ROOT and open it. Then scan down till you find some keys that start with "Janus" -- these will be the Interface objects. You will have to determine which object interface is applicable to the PEM you want to access; this should be documented with the Janus Grid.
