Even if you disable copy/paste, everyone can simply read that value from the screen and type it into Notepad. Why would you want to do that, anyway?

If that's the case, why wouldn't you hide that item? Either set its DISPLAY property to NO, or put it to a NULL canvas.

I think that you should explain the whole problem in details so that someone might suggest a solution. Discovering piece by piece leads to confusion. At a moment, SET_ITEM_INSTANCE_PROPERTY is what I can think of (but that doesn't have to be "it").

Ok then let me explain the whole thing.

There are 3 users of my data base. In abc table each of them have some data. The requirement is one user will only able to view his data only. That's why i had to use set_item_instance_property with such visual attribute which will minimize the font size of data of other user. But the problem i am facing is though the font is very small the user can copy it and paste it to any notepad software where he/she can view the data of other.

That is why i am asking about any technique even PJC if you preffer just share the idea with me.

Create a DEFAULT_WHERE clause that will contain a condition that restricts fetch according to a current user. Set it with SET_BLOCK_PROPERTY. Doing so, every user will see only his/her own data (I suppose there's a column that distinguishes users one from another).

Thanks for your idea,
but there are certain item of the table that should be viewed by every user and some confidentail items are there where view is restricted hopefully now you have understood the problem.

Please help.

Your data model is wrong. The restricted items should be in a different table to the common ones.
The only safe way to stop users accessing data in forms is to change the where clause to prevent them querying that data.
