varchar to nvarchar: TStringField to TWideStringField? How?

[brace]

Hello
I am using Delphi 2009 and Latest SDAC(470).

I changed all my DB varchar(n) fields to nvarchar(n) to support unicode.
These fields which were earlier generated as TStringField (using Fields Editor of TMSQuery Component)
now i need to change them TWideStringField while i expected them to be either changed automatically or automatically taken care without any change.
Can u please suggest the way to handle this issue, because changing this in entire program may not be feasible.

We do not provide any automation for this purpose. You can use any tool that has the "replace in files" functionality to change your *.pas and *.dfm files.

Ok, so I will use the technique (with free tool NotePad++).
I just aked to see if there was a better way.
Thanks.

I belive the GExpert Tools can do that for you.
