vba to prevent copy paste, drag and right click on one or multiple columns

what is the vba (not using protect sheet) to prevent copy paste, drag and right click to one column only - say, column A.
or maybe a set of columns range A:E
many thanks

thank you for your reply.
the codes you posted prevents copy paste to the whole worksheet.
what I am requesting is to prevent only on a certain column or range of columns - not the whole worksheet.
many thanks..

thank you for the reply.
the code is preventing data entry.
it should allow input of data but not copy paste.
sorry I might have missed it in the OP.
many thanks..

thank you very very much...

sorry - spoke too soon.
the code I inserted - it is preventing the DRAG beyond the 4th column - as a matter of fact - to the whole worksheet!
how can we control this for up to the 4th column (D) only?
again - many thanks..
