You probably will have to use that function, if you're using it from CF. Using COM can be problematic under the best conditions, and CF isn't the "best conditions' for COM. > If the COM object is not killed and I have two people working on the website > will their > PDFs collide?

This depends on the threading model (if any) for the COM object, but in the absence of that information I would assume the worst. > If I cant get the COM object to store as a session or application variable I > will probably > end up storing the created PDF name as a session variable and each function > will go > open that PDF and add the image, text etc then save the PDF back down. > Probably a > safer way of doing things. You could also treat the COM object as a singleton, by locking access to it so that only one request can use it at a time, and you don't have overlapping requests performing multiple concurrent operations. But in any case, you will almost certainly have to handle this yourself, rather than relying on the good graces of the COM object in question.
