Without writing a single line of code, you can define several view attributes such as the resolution, zoom, page view mode.

Protection of 4D Write Pro dynamic expression evaluation

Automatically translated from English

With 4D v16, 4D Write Pro is now providing a higher level of protection regarding the evaluation of 4D expressions in documents.
Developers can now fully rely on 4D for checking the evaluation of these expressions. By doing so, end-user machines and databases will be automatically protected from any possible side effects.

A valid 4D expression can be a field, a variable, a 4D command, a statement returning a value, a project method, and so on.

Starting with 4D v16, “unsafe” 4D expressions will no longer be evaluated and an error will be displayed instead.
