My application has to launch Paradox (any version) and run a report. I am fighting a losing battle to get CreateProcess to work. However, I still want to use this call. How do I get it to work? Assume I have the path to the correct version. Part 2: How can I disable my app from opening another version of this report; don't say, disable the button, because I still need to re-enable it, which brings us back to the same problem.
