Why?? The following is perfectly legal in Delphi 7 and Kylix 3 using
dbExpress components.
=========================
procedure TForm1.SQLConnectionBeforeConnect(Sender: TObject);
begin
with Sender as TSQLConnection do
begin
if LoginPrompt = False then
begin
Params.Values['User_Name'] := 'SYSDBA';
Params.Values['Password'] := Decrypt(Params.Values['Password']);
end;
end;
end;
=========================
What I am suggesting is simply that the dedicated properties Username,
Password, Charset, etc. check it field variable first and if it's
blank, then as a fallback it checks the Params values.

For TSQLConnection, the GetCharSet getter method will simple return
FCharSet field variable as a result. This means by default everything
will work as is. Descendants of TSQLConnection can then extend
GetCharSet by looking at Params values (only as a fallback, if
TSQLConnection.GetCharSet returned an empty string.
