excel - Setting numeric constraints on variables -


is there way put constraints when creating variables in vba?

example: dim alfa integer

now i'd excel accept only values 0 99, how can that?

many thanks

you validate this:

sub test()     dim integer     = 100      if not (i >= 0 , <= 99) err.raise number:=6, description:="number not valid"      'continue use end sub

you create new class, accept values. in cases overkill, here is:

put standard module

sub test()     dim specialnumber snumber     set specialnumber = new snumber      specialnumber.value = 1     specialnumber.value = 100 'this line throw error end sub

then put class module , name module snumber

private specialnumber integer  public property value() integer     value = specialnumber end property public property let value(v integer)     if not (v >= 0 , v <= 99)         err.raise number:=6, description:="number not valid"     else         specialnumber = v     end if end property
