How to change feature visibility programatically?

[Colin Richardson]

Hi All,

I'm looking to hide certain attributes via an add-in.

Normally I try the automation interface, then profile the database to work out how to do it directly via SQL, but this time, no luck.

Any ideas?

[Geert Bellekens]

create a new project with one class and two attributes.
Hide one attribute.
Then open the database and open each table that seems relevant to figure it out.

PS. sometimes in the database they use the first part of the ea_guid in style-like columns to indicate a certain feature.

Great ideas - still no luck though.  Even tried building dynamic SQL to look for matching IDs, GUIDs, parts of GUIDS.

Any other ideas?

The fields that change are t_diagramobjects.ObjectStyle and t_diagram.StyleEx (look for a property named SPL), but I can't help you any further because I have no idea what it all means...

[Colin Richardson]

Legend!

Yes, SPL is the key - it's a list of the most 3 significant bytes of the GUID (6 characters) for each attribute.

Don't know how I missed the change  

Thanks again - thought I was going nuts :-)

Keep working with EA and you will...

After 6 years, I'm sure there's nothing wrong with me...  wrong with me...  wrong with me...

But since you're interested in rendering in EA, check out: Consistent Diagram Item rendering proposal and lend your support...
