Passing some parameters from 64bit exe to 32bit dll?

[luckiejacky]

The caveat is that it works, you can call over from 64bit exe to 32bit dll...
I need to use a 32bit dll in that case is that I need to use that dll to hook a 32bit program.
And now I want to supply some parameter information to the dll, which is just a path name.
Any ways I can easily achieve this?
Thanks
Jack
