How to determine if a connection is active
 

I am writing an addin that manages an ODBC/OLEDB connection to a
database. I manage to make the connection without trouble. However, I
would like to be able to determine if the connection is still active;
for instance, the database might drop the connection if a certain
amount of time has passed without activity. How can I determine if a
connection is active?

Many thanks,

Phil

How to determine if a connection is active
 

check the .State property
of the adodb.Connection object

anyway..
you should not needlessly leave the connection open.
close it when done. reopen when need.

How to determine if a connection is active
 

That works fine. I'm testing for .State = 1 to determine if a
connection is active. Would you happen to know the values that .State
can take on? I'm sorry to ask, but the ADODB help library isn't
installed on any of the machines I have access to.

And I agree with you that I shouldn't needlessly leave the connection
open. But I have rather a strange situation where it makes some sort
of sense to let the user manage the connection rather than trying to do
it in my program, and I prefer to test if the connection exists rather
than trap the error that occurs if it doesn't exist.

Thanks for the help.

Excellent reference. Thank you. I should have searched harder after
finding the appropriate help file wasn't loaded.

Thanks,
