I think my salary doesn't justifies that title. Plus, I don't know if I
want to be associated with such a saintly moniker. The members of the IDL
EPA seem like quite a raucous bunch and I would like them to think that I
could fit right in.

Wow! Everything is changed in a day. Thanks Karl and Andrew for
responding to my mail and special thanks for my God,Rick Towler, for
letting us see his efforted source code :) Thanks you all again.

I have written a direct input DLM that you may want to look at. You could
easily fold force feedback effects into it and you would get the keyboard
and mouse for free.
Compiled dlm and example program and docs are available here:
http://www.acoustics.washington.edu/~towler/directInputDLM.h tml
Source is here:

Go talk with God, aka Rick Towler, who has done all this
for you already.

You might consider using the ul (ULONG) member in IDL_ALLTYPES to pass the
DD handle around. Also, ptrint may be a better choice if you have 6.0.
You would need to cast the handle to a LPDIRECTINPUT8 in the Destroy
routine, and in any others that need the handle.
So you might want to try something like:
In create:
IDL_VPTR vpHandle;
vpHandle = IDL_GettmpULong((IDL_ULONG)g_pDI);
return vpHandle;
In destroy:
LPDIRECTINPUT8 pDIID;
pDIID = (LPDIRECTINPUT8) argv[0]->value.ul;
Code untested, but may give you an idea.
