Help for share variables between Application and DLL

I'm new of writing DLL and I have a problem for share variables between my
application and the DLL.

Usually I use the parameter in DLL function for passing the variables to the
DLL.
But that is not really work if I have more than 10 or more variables for
share?

What is the usually method for share variables between application and DLL?

The most common method is to use memory-mapped files. A search of

Hi there,

why don't you make a record of them?

Just pack them all into a record and pass the record to the DLL (as Var
parameter if you need the DLL to pass changed data back).
