>Maybe I need to explain again what I want to do. I build a class in VFP and compile it as a DLL. On the build dialog I can set the version number for the DLL. In the class, I want to be able to get and return the version number of the DLL. This is easy with AGETFILEVERSION(). But, I have to know the full path and file name for the DLL, which I won't always know. So, from inside the class, how do I figure out what DLL it is in?

Just a SWAG, but have you tried FULLPATH(SYS(16)) in the Init method of the class?
