I knew that from the COM work I've done in the past, but for some reason never made the connection between it and useability in other languages through a plain old DLL. I might go back and switch everything over to WideStrings as I'm still at the (relative) start of the project still. At the very least it will make the code look a little cleaner. > That often indicates that you're trying to free something > that wasn't allocated using the same memory manager.

Then my problem was that I hadn't allocated enough space for the #0 character on the end. One of those traps that, again, I knew about, but I still fell into it. Once I allocated the extra bytes it all worked nicely. Thanks again for your help Rob.
