Well, I run most of my vfp dlls from IIS and I can run the following automatically when I recompile from a project hook:
DirObj=GetObject("IIS://LocalHost/W3SVC/1/Root/"+JustStem(cOutputName))
DirObj.AppUnload
where 'JustStem(cOutputName)' is the name of the virtual directory. This is just ADSI code, I believe, so maybe you can do something similar with your non/iis mtdll.
Any Microsoft people know anything about this??
