Hi Roy,

Yes, I thought about this as an option, but that would mean changing the
registry setting when launching each application.Which seems to be the
same as having a Config=xxxx in the connection string, and Tim is saying
that I shouldn't do this.

Without having a configuration file for each application I dont see how
this can work.

Another scenerio comes to mind as well.

What happens if I write a program for a customer and it sets up the
configuarion file. Then another company writes an app. using ElevateDB
ODBC and tries to install onto the same customers computer.

Are we supposed to share a configuration file?

I have just checked the manual on the ElevateSoft web site for the Win32
 version and it shows that for each application you can change the
configuration file by setting the path in the engine so I would have
expected the same functionality for teh ODBC driver.

However all of this could be a mute point as I was planning on using the
ADO driver when it becomes available.

Tim, will the ADO driver allow a configuration file per. application
like the Win32 system? (In which case I can forget all about the ODBC
driver)

My reading of Tim's response was that you couldn't do it once the engine was active. Before do what you like.

Hi Roy,

If another app. is using the ODBC driver I might not know that the
engine is in use.

Intriguing. Not having used the ODBC driver I don't know but wouldn't each app have its own instance of the engine? Otherwise you would be limited to one config path per PC or network or something.

In these circumstances I suggest "suck it and see".

Roy Lambert

Hi Roy,

Yes, I expected that each connection of the ODBC driver would have its
own engine, but that does not appear to be the case. It appears that
each computer is given a configuration file and all applications have to
share it!
