force unload of .dll

[augusttech]

Is there any way to force the release of a .dll in both NT40 and WIN2000? With many systems periodically calling a host communication file, I need a way to verify the file is not in use so it can be upgraded.

WIN2000 has .dll caching - anyway to clear this cache?

Thanx in advance.

Bad day to ask PAL.

I was looking for answers re Win98 onwords. There is something in the Visual Studio/MSDN Help files that seems to be saying that if the "Object" has been released then the dll unloads after about two minutes. OS not specified so I assume it is general. My problem is that the object it refers to is not a form but seems to be the whole application unless it is a feature of the interpreter and compiled programs behave differently. I am considering an independant app loaded by the instigator which self unloads. Only then can I delete special files that have been used as DLL's

(well so much for the theory - now for the practical).
