Speed my table opening
I use in application two tables and two radio buttons .
When I click first button I open ... two databases in tables and when click the second button ....replace these with anothers .
When click the second radio button I pop-up a menu,too :
Table2.Close;
Table1.Close;
Table1.TableName:=Path+'Da
Table1.IndexName:='Gratuit
Table2.TableName:=Path+'Da
Table2.IndexName:='Gratuit
Table2.Open;
Table1.Open;
Menu.AutoPopup:=True;
Menu.Popup(0,0);
When run for the first time my app I have a 4-5 seconds delay before pop-up the menu .
Close the program .
Every time when I start the app after that the pop-up is displayed instantly .
How can I remove this delay for the first running ?

IMHO, you must write a small dummy application like Microsoft OSA (form MS Office) which will slow down end-user computer during startup and ;-) maybe entire session :-))
You might not be able to remove the delay. It is most likely caused by DLL loading and BDE initialization. Once that has been done, subsequent executions don't experience that overhead.
You might be able to mask the delay by invoking some similar process during application startup (with a 'splash' form). Also, you might this initialize task happen when the user is inactive or reading form content.

when you open the table, bde create temporary table on the memory (or harddrive ?), it always slow on the first time, but you can try to optimize in the BDE Administrator (in the control panel), go to the "Configuration" tab > System > INIT, try to modify all the property, like MTS SPOOLING.
Some time I use TQuery instead of TTable, I find it faster.

you can't
as aikimark commented,
its because the bde
must initialze itself and
this take a bit time
i usual use a splash-screen,
as aikimark suggested,
with a nice picture and a bit text
(like tip of the day)

But the BDE is already initialize because at OnCreate I already have opened anothers tables.
Table1.TableName:=Path+'Da
Table1.IndexName:='Gratuit
Table2.TableName:=Path+'Da
Table2.IndexName:='Gratuit
Table2.Open;
Table1.Open;
Table1.TableName:=Path+'Da
Table1.IndexName:='Gratuit
Table2.TableName:=Path+'Da
Table2.IndexName:='Gratuit
Table2.Open;
Table1.Open;
if it already initialized,
and you've already a delay,
then raise the memory-entries at the
bdeadmin-configuration-sys

if you've a single-user app,
open your tables with the exclusiv-property set to true
