I'll be surprised if I get an answer to this one, but, here goes: Is there any programatic way to tell the ActiveDoc being loaded which VFP Runtime library to use. The default seems to be the distributable dll, but, I want to use VFP6.exe because one of the commands in the app requires it. I know you can do this from the toolbar, but, I need a way to do it as a command line argument, config file, or in the app. Definite stars for anyone that helps...
