[DUG] call a method function from outside object

[Guy.Brown at sungard.com]

Hi Ross.  My Delphi is a bit rusty but I believe it's just:

DLLOpen := Open;

Assuming that DLLOpen is declared as a procedure of object with the
appropriate parameter list.

In trying to solve this I thought of using method functions inside an
object rather than standard functions, and then assigning the method
pointer to the DLL, but I can't seem to do this either.  eg. In a class
procedure I do this...

  DLLOpen := TMethod(Open).Code;  <<< Invalid typecast

Open is a function defined in the same class DLLOpen is the function
pointer defined in the DLL which I need to assign to the method pointer.

I'm not sure why this doesn't work.  My only other option is to use
global variables!

Ross.

In a component I'm writing, a DLL needs access to a standard function so
this is declared outside the main object.  Within this function I want
to access variables and methods inside the main object, but I can't find
a way to do it.  Is this possible?

Thanks,
Ross.
