Borland Database Engine (Error $2108)

?
i've a car, there is no engine in,
how to get the car drive without installing the engine?

its not really the main problem,
because i want only to hear the sound.

(just impossible)

you've to install the bde

meikl ;-)

>> And 'no', I don't want an Expert to reply, "Install the BDE engine!"  <<

I don't know how much clearer I could have made it...

Kapusta,

Your program can of course run on a pc without the BDE installed, but only if no database component will be accessed or initialized.
You can trap any BDE error with a TRY...EXCEPT, but you need to know exactly where the error is raised. Therefore the best thing you can do is to launch the program yourself in your compiler, but without BDE. You can temporary rename the \Program Files\Common Files\Borland Shared\BDE folder (assuming your BDE is installed there). Now you can simulate and locate the error your friend is seeing when the program is lauched, and program some traps there.

Hope this will help.

Does not seem to be any need for the TDBGrid, TDatabase and TDataSource components if you are not going to install the BDE. Why not just remove the components.

Chances are the TDatabase component is generating the error.

I never said that there was no need for the components.  My friend is not the only one running the app.  I am using the app on my PC, which has the BDE.  I use the table.  My friend has no need for the table.  I have no desire to write 2 versions of the program.  Therefore all I want to do is suppress the error message for those users with BDE installed.

>> for those users with BDE installed. <<

Typo correction:

for those users withOUT BDE installed.

I have renamed the BDE folder as per your suggestion.  I then ran the code in the IDE.  The error occurs on the Table1.Open line.  Adding Try/Except, however, does not suppress the error window.  When compiled to EXE, the same error message window appears.

Here's the current code...

     Database1.Open;
     try
          Table1.Open;
     except
          // BDE engine not installed
                // Error window appears
     end;
