Prevent copying objects by the user

Hello,

what's the correct way to prevent copying objects by the user.

I am currently throwing an exception inside the OnCopy procedure of the
object module.

Thx for your help!

Oliver,

the platform design implies that copying is just creating a new object (plus filling it with some data). Therefore, providing a special tool that prevents copying just does not seem right.

Throwing an exception inside the OnCopy procedure looks like the best solution to me.

Hi, Oliver.

If you don't want to show message box with error there is another solution.
You can hide button "copy".
Open form in Designer, open form's properties, click "open" in the row "command set" and uncheck "Copy". You must do it for all forms.

Unfortunately, in the list form key F9 still works.
We can prevent it with this code.

&AtClient
Procedure ListBeforeAddRow(Item, Cancel, Clone, Parent, Folder, Parameter)
   If Clone Then
      Cancel = True;
   EndIf;
EndProcedure

&AtServer
Procedure OnCreateAtServer(Cancel, StandardProcessing)
   If ValueIsFilled(Parameters.CopyingValue) Then
      Cancel = True;
      Return;
   EndIf;
EndProcedure
