I have a third-party written dll with no documentation. It is "registered", and implements a context menu item when right-clicked on a particular file type. I'd like to be able to both identify the entry point for the dll, and be able to simulate the context menu option programatically, e.g., via VBScript.
The dll is written is C++, and I do have the source code, but it is quite opaque to me (my exposure to C is limited). If the code would be useful, I'm quite prepared to post it up.
