Icon repository - block forbidden file types (or give a Validation-error)

The File storage extension whitelist only works in combination with Indicium, so with the Universal GUI it will automatically be restricted to the allowed extensions. The Windows GUI sadly does not abide to this whitelist. 

You are able to create your own validations that validate this for example. The validation code (Version >= 2023.1) would then be:

insert into validation_msg 
(
    model_id, 
    branch_id, 
    validation_id, 
    pk_col_1, 
    pk_col_2, 
    pk_col_3, 
    pk_col_4, 
    pk_col_5, 
    pk_col_6, 
    pk_col_7, 
    generated, 
    insert_user, 
    insert_date_time, 
    update_user, 
    update_date_time 
)
select
    @model_id,
    @branch_id,
    @validation_id,
    @model_id as pk_col_1,
    @branch_id as pk_col_2,
    icon_id as pk_col_3,
    icon as pk_col_4,
    null as pk_col_5,
    null as pk_col_6,
    null as pk_col_7,
    1,
    dbo.tsf_user(),
    sysdatetime(),
    dbo.tsf_user(),
    sysdatetime()
from icon
where model_id = @model_id 
  and branch_id = @branch_id 
  and icon like '%.ico'
  and generated_by_control_proc_id is null

@PatrickW, do you consider Mark his reaction as a solution to your idea?

Yes, I have added this validation in our Base project. Thanks.
