Subject: BUG REPORT

NAME = Samuel Natali Junior
EMAIL = samjr@ibm.net
email-address = nobody@166.72.32.111
CATEGORY = Visual Component Library (VCL)
BUG = VLC DBEDIT x MESSAGEDLG
DESCRIPTION = When I call the function MessageDlg (or any other Message
functions)
in the dbedit.Exit event, the second dbEdit field does not change the
modifications in database. 

To resolve this problem, I insert this line:

	Procedure TForm1.DBEdit2Change(Sender: TObject);
	begin
         	dbEdit2.Field.AsString:=dbEdit2.Text;
    	end;

This sample program demonstrate this problem.

uses
  Forms,
  Lixo in 'LIXO.PAS' {Form1};

{$R *.RES}

begin
  Application.CreateForm(TForm1, Form1);
  Application.Run;
end.

SOLUTION = To resolve this problem, I insert this line:
