Calling functions form undocumented DLLs

I=92ve endlessly tried to find a program that will show all exported
functions from a DLL that includes information about the parameters that
have to be passed to the functions and the results of the functions. In
other words, I=92m looking for more information than the Quickview app in=

windows can give. Anyone have any suggestions?

This information is not stored in the DLL unless it includes debug
information. It is theoretically possible to disassemble the DLL
functions, and by looking at the assembler code guess on the number/size
and in some cases the use of passed parameters. As far as I know, there
are no secure ways of determining this, however.
