 Posted: Wed Feb 18, 2004 2:47 pm Post subject: Is it possible to pass a TADOConnection to a Delphi Built DL |
 |
|
I want to call a function in a Delphi built DLL that creates a report.
However, the report is already resource extensive and I don't want to take
time to initialize a database connection by passing a connection string. Is
there a way to pass a TADOConnection that is already connected (Connected :=
True;) to the DLL?
Thanks,
Bill N

Bill,
The tadoconnection component has a property called connectionobject. Pass
that to the dll and have the dll assign it to it's tadoconnectionobjects
connectionobject.

I am looking for sample code or articles relate to this issue, how could I
pass a connection object within packages (BPL)?
thanks in advance.

If you are calling the dll from a Delphi App you should just change to
using a
Package instead of a DLL. That way you can share the TadoConnection

Hi,
How about in design time? How could I use the TADOConnection VCL in another
package?
Thanks in advance

Pass it like you would to any method in your Exe. When you use a package
you
can treat it just like a module of your code.
