Adding Custom Property to EA project or database

[Mithal]

Hi.

How can i add a custom property or user property to my EA project or database.

Here is the scenario.  Every time the EA_FileOpen event fires, i want to check the repository for this Custom Property or User Property that i added.

If i find this property or not then i can do something.

Thanks.

Mithal,

Do you want one property for the whole repository, or one for each element?

One for the whole repository.

I am currently using this:
EA.PropertyType tagType = (EA.PropertyType)Repository.PropertyTypes.AddNew(property, "");

there is more code to this, though.

Is it the correct one or have i gone of in the wrong direction.

Thanks

The property types are actually the predefined tagged values you can set using "Settings|UML|Tagged Value Types"
The downside of this is that users can start using this tagged value on their elements.
I don't really see an obvious better choice, you could use things like Repository.Terms

Another option is to (ab)use the notes field of the root model(s).
You can find them if you search for t_package where parentID = 0.
That notes field isn't displayed in EA and is also not editable by the users, so they can't mess up your solution.

Ok.

Can you help with some sample code ?

Thank you.

To set your property you could do something like

Code: [Select]

foreach (EA.Package rootModel in myRepository.Models)
{
   rootModel.Notes = "myProperty";
   rootModel.Update();
}
To read it you do something similar

Code: [Select]

boolean hasMyProperty;
foreach (EA.Package rootModel in myRepository.Models)
{
   if (!hasMyProperty)
   {
      hasMyProperty = rootModel.Notes.Equals("myProperty");
   }
}

That works Geert.  Thank you.
