See below, when i try to open my string "XML", i got this error
Run-time error '3709': The application requested an operation on an object
with a reference to a closed or invalid Connection object.

i'm on MDAC 2.6
I know there a bug report on Knowledge DB, but the solution is : install a
recent MDAC like MDAC 2.6. But i'm already on MDAC 2.6 !!!

If someone can help me.
