First off, why are you asking a non-COM question in COM and OLE
groups? ;-) For future reference, this type of question would be
better places in an API group.
You can explicitly load the library before calling anything in it
using the LoadLibrary API function and then call the FreeLibrary API
function to free the library when you are finished. This works
because VB will check to see whether or not the library is loaded
before making a call to it and if it isn't already loaded, it will
load it. You could also just call FreeLibrary enough times to unload
the library before attempting to delete it.
In any case, you will want to make sure that you either load a new
version of the library or that you app does not make any further calls
to the library because you will get an error if the library is no
longer present.
HTH,
Bryan
