DLL question.

I am creating a DLL in VB 6 and would like to know if there is a method that will give me the full path of the object that called the DLL. I will be using an excel macro to call this dll and would like to know the full path of the excel workbook that made the call to the dll, without having to pass it to the dll. I have loaded the Microsoft Excel references in the add ins section.

Anyone know if this is possible?

Thanks in advance.
