Accessing cellview ID which is stored as a string

RK56

Hi,

I'm into a situation now that I have stored a database ID (cellview or object ID) as a string. Like this

a = sprintf(nil, "%L" geGetEditCellView())

b = sprintf(nil, "%s" car(geGetSelSet()))

Now I am trying to access the cellview ID through the variable a or b as follows

evalstring(a)~>cellName

evalstring(b)~>width

Evalstring does not work here. Is there any other function which can do this job?

Why am I doing this?

Say I want to store some layout objects ID inside a report field along with other information. And when user clicks any row in the reportField, the CB should be able to zoom to that particular object.

Is this is a right approach or are there any other elegant way of doing this?

Thanks

Ramakrishnan

  • You should not do this - mainly because it will not and cannot work. You cannot go from the print representation of a database object back to the actual database object. A better idea would be to create a table (or array) indexed by the report field item number and store this table/array as a user defined property on the field. The values of the entries in the table/array would be the database objects.

    Even so you need to be careful - if your form is non-blocking, it's possible that the objects might not exist when you try to operate on them (they may have been deleted by the user, say). Also, db object ids can be recycled, so the id might exist but may no longer be the original object. So caveat emptor...

  • Thanks Andrew. I had the idea of creating a table but to keep it as a global variable. I was not knowing that we can add a user defined property to the hi*fields. Should I be using putpropq and getq functions?

    By adding extra properties to reportfield, can the GUI go slower(less responsive) if the attached table grows in size?

  • Hi Ramakrishnan,

    You can add the property using getq/putpropq or you can just use the -> or ~> operator (-> corresponds to getq/putpropq anyway).

    It won't affect the performance in any way since the UI code knows nothing about the property you've added (and anyway, it would only be a single pointer - the table itself is just a normal SKILL table).

    Regards,

    Andrew.

  • Thanks Andrew for the tip. Adding a property to a form was a wonderful idea to avoid global variables. Now I have added even the high light set with the form(which I was using it as global) and I should revisit my previous skill scripts to make use of this feature.
