A foreign function library means that the Python code can call C functions using only Python, without requiring special or custom-made extensions. WebMicrosoft originally suggested DirectCast was a back-end construct that you don't need to know about -- just use CType.But everyone who understood the difference used DirectCast when casting. The point about CType is that it can try both conversion and casting, if required. So when you really don't know what could be in an Object you might just use …
