[sqlite] dbExpress

[Bert Verhees]

Hi, I am using the dbExpress-driver from Marco Wobben, maybe he can answer 
but I do not want to overload him that's why I rather ask on a public forum first, and 
he has the opportunity to answer if it is convenient.

Works fine, but I have one question. Maybe someone knows the answer.

I fill in the params on execute-time of the application.
That is because I do not want to provide ini-files, etc. And I want to change the 
database-file-name on runtime.

I am writing in Delphi, probably want to write this for Kylix too (that's why 
dbExpress), but first have it running in Delphi, and I experience following problem

I fill in the params with following code (FDM is the datamodule):

 FDM.MetaDB.Params.Clear;
 FDM.MetaDB.Params.Values['DriverName']:='SQLite';
 FDM.MetaDB.Params.Values['RoleName']:='Cache';
 FDM.MetaDB.Params.Values['Cache']:='2000';
 FDM.MetaDB.Params.Values['TextLength']:='1024';
 FDM.MetaDB.Params.Values['Database']:='meta.db';
 FDM.MetaDB.Connected := True;
If the file meta.db does not exist I want it to be created on the current directory, but 
this does not happen, it keeps complaining about a not existing database, even 
generates an exception.
So, someone who can tell me how to generate a new database-file using a 
dbExpress environment?

Strange thing is, it did a few times generate a database-file but suddenly stopped 
doing that, I don't know why

thanks in advance
Kind regards
