Is it possible to change a database field-name from within a running application?How do I do it? As an example: Say I have a database that looks like this:
Fields: Cartype   Color   Prize   Weight   Height
Posts:
        Sedan     Red     12000$   1200 Kg 1.2 m
        Truck     Gray    86000$   6500 Kg 3.2 m
        Racer     Green   45000$   800  Kg 0.85 m
Now! How do I change for example the fieldname "Prize" to "Cost" from an running application?
PS. I run Delphi Developer 2.0 and the database is a Paradox-base...
Thanks!

Do you want to change the field name just for the one run of the application, or do you want it changed permanently??

The field-name within the application is probably not what you want to change.  I assume that it is the label displayed on the form that is relavent to you.  Obviously you can set up some logic in the OnShow method of the form to change the field labels.

Alternatively if you are displaying the Posts using a dbGrid component then you can also use logic to change the field's 'DisplayLabel' i.e.

         tblName.fieldbyName('Prize).Displaylabel := 'Cost';

Simarily you can also control other properties of the column :

        with tblName do
        begin
            fieldbyName('Prize').Visible          := true;
            fieldbyName('Prize').Readonly     := true;
            fieldbyName('Prize').DisplayWidth := 10 ;
       end;

I hope this is useful to you.
