I decided to distribute for testing a part of my application on
another PC and met the following problem :
The code to connect to the database that runs correctly on my
machine raises an error mentioning that it is impossible to open the
file "" and that the specified access path cannot be found.

Here is the code :
FDBPath := ExtractFilePath(Application.ExeName)
+ 'Database\BDCOCAGNE_PLC.FDB';
With DM_Cocagne do
begin
with IB_Connection1 do
begin
Connected := False;
LoginPrompt := False;
Username := 'SYSDBA';
Password := 'masterkey';
Server := '';
Path := FDBPath;
Protocol := cpLocal;
Connected := true;
end;
with IB_Transaction1 do
begin
if InTransaction then Rollback;
AutoCommit := True;
IB_Connection := IB_Connection1;
Isolation := tiCommitted;
RecVersion := True;
end;
end;

I decided to activate the login prompt instead. But I still have the
same problem.
It seems as if the path is set to blank.

Or may be it's another problem relating to the way the data
components have been compiled ?

If anyone could bring me some light to my problem, it would be great.
Thanks in advance
