Is it possible to convert a 32-bit pointer to a 16-bit one?
The reason I ask: My project consists of two parts: a 32-bit Delphi
program and a 16-bit DLL made in Delphi. The 16-bit DLL is behind the
scenes and is never seen by the user. I'm using DDE to send stuff from the
32-bit program to the 16-bit DLL. But what I need to do is send a pointer
(which points to some chunks of data used by the programs) from the 32-bit
program to the 16-bit DLL. Since 32-bit pointers are in a different
format, the 16-bit DLL can't read them. Is there a routine that can
convert one to the other?
-Please respond to my email address.-

Yes. The easiest (but slowest) is to use WM_COPYDATA.
An alternative is to allocate using GlobalAlloc and send the
handle over.
