Do you see the actual signature, even though the TEDBEngine on the form is
still missing the signature in the object inspector ? >>

Hi Tim,

Although I have the unicode working under the base Lazarus 926, in Runtime I'm still
getting an error EEDBException with message:  ElevateDB Error #406 Invalid data type
identifier ''.

With this table active in the Design-Time I see the data just fine.

I added a button click with the following code:

 ShowMessage(EDBEngine1.Signature);
 EDBEngine1.Active:=True;
 ShowMessage(EDBEngine1.Signature);

and it shows me 'edb_signature' both times.

Any ideas on the Runtime error?

Cheers,
Todd

It's the same issue, and I seem to have found the source of the problem.  It
appears that you were close with your theory about assignable constants,
because the problem is that Lazarus (Free Pascal compiler) is not coping
with the constants declared like this:

  DEFAULT_SIGNATURE = TEDBString('edb_signature')

It treats them as blank, whereas the same constant declared like this:

  DEFAULT_SIGNATURE = WideString('edb_signature')

works fine.   This is a bit odd, however, since the Unicode version of EDB
declares:

  TEDBString = WideString;

So, I'll report this as a bug and see what they say about a fix or
workaround.

Hi Tim,

Thanks for the update and your help on the problem.  I'll keep a watch out on this thread
to see when the Lazarus team has a solution or work around.

Have a great weekend!

Wow, I can't believe they already fixed it!

Being new to this arena, how do I go about getting the patch for the compiler so that I
can give it a try and hopefully get on with the project . . .

Interesting - we now have something that its worth benchmarking your standard or support against <vbg>

Good question.  I think that you have to use the snapshot versions that
they issue on a daily basis here:
