Is it possible to extend or modify an object?
For example, I need an EDIT object that accepts just Alphabet and numbers. (no symbols, no space)
Tnx.

here some code it needs only one simple sub
and in the string you put what you want the editbox to accept.
best regards


`=================================================
`=edit box that only exepts alphabet and numbers.=
`=================================================
object myform as form
  object editbox as edit
    onkeypress=filter
  end object
  showmodal
end object

sub filter(key as byte)
  if instr("ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890",ucase$(chr$(key)))=0 then
    key=0
  end if
end sub

It works perfect, tnx a lot!!!
(but could be interesting to have possibility to extend objects.)
