Hi
I have a VB6 application and now need to add communication with a USB 2.0
device. Unfortunately, I only have access to a C++ .lib file and not the
corresponding DLL. How can I use the .lib file or is it possible to convert
the lib to a dll

I assume this is an object library rather than an import library (An import
library needs a DLL, as the LIB merely describes the DLL's exported
symbols). Object libraries can only be used by code compiled using the same
compiler that created the LIB in the first place, as code in an import
library is merged with your object code (you have no runtime library setup
or other ILC functionality). As a result, very little code is distributed in
object libraries, as such distribution is essentially pointless. A noted
case is the Microsoft OpenGL GLU/GLUT, for which your best bet is to create
a DLL / import library (I have done this) using MS C++.
