Hi,

I'm evaluating the test version of QuickOPC 5.4 at the moment. Reading and writing values to a OPC-UA Server is pretty easy, as long as you find out the nodeIDs with your example dialogs. But I tried to implement my own browsing dialog in Delphi, but I'm facing some problems which I don't know how to handle.

Actually I couldn't figure out, what to pass to the EasyUAClient.BrowseNodes Method for parameter nodeDescriptor. In the reference, UAObjectIDs.Server is passed for start browsing from root, but I didn't find any Delphi equivalent.

I tried to modify this example for my needs:



I would really appreciate some sample code for this.

Best regards
