Hello,

I'm trying to set the value of InputsOutputs.CurrentNodeDescriptor.EndpointDescriptor.EndpointSelectionPolicy on a TUABrowseDialog instance.
(I have persisted this value from the previous usage of this dialog, as a way to re-use the selectionpolicy that was used 'last time').

I can't seem to find the way to do it in delphi.

The documentation (opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...76-743d-4032-a0fc-3c94b499e014) seems to be saying that I just need to set the value to whatever i want (as long as it's not null, or nil in delphi).
The problem is that EndpointSelectionPolicy is not an instance of an object but of '_UAEndpointSelectionPolicy' which is some kind of interface.

_UAEndpointSelectionPolicy = interface(IDispatch)

I do not know how to appropriatly use this and how to set its value.

Can you provide some guidance and idealy some examples for it?

Best regards,

Mathieu
