Connect to element feature by Automation?

[Paolo F Cantoni]

This is nice functionality, but I couldn't see how to do it by automation.  Is it possible?

TIA,
Paolo

I'm pretty sure you'll find that in the custom properties of the connector.
(In the database the connection to an element feature is stored in the t_xref with name "CustomProperty")

Just had a look and t_connector.StyleEx is getting the value:

Code: [Select]

LFSP={<guid>}R;LFEP={<guid>}L;
I'm guessing that LFSP is Linked Feature Start Property and LFEP is End Property. The R and L denote which edge of the object to attach to. The <guid> refers to t_attribute.ea_guid. The help for Connector.StyleEx in the Object Model says "Advanced style settings. Reserved for the use of Sparx Systems." so exercise caution, but you'll be pleased to hear it's read/write.

Indeed, the magic string on my little test in the StyleEx reads:

Code: [Select]

LFSP={1D7A2E6F-94BD-4862-8E07-2F35F889DFF3}L;
and the GUID is indeed the GUID of my attribute.

Thanks guys (especially Sparxian Neil),

I'll give this a go in the next few days.  At present I'm involved in the Visio import problem mentioned in other posts.

It's good to see Sparx being more forthcoming about the internals of EA.

While I greatly appreciate Neil's input, I'm a little concerned that he's guessing.  While the guesses seem reasonable enough, it would be better if a Sparxian (at your leisure) could formally confirm his input.

The only guesswork was what "LFSP" stood for  8-)
