Can you access 32 bit DLLs from 64 bit code?
Migrating your 32-bit Windows application to a 64-bit machine can be problematic if you have 32-bit DLLs that you cannot re-write. Mike Becker shows you how you can access 32-bit DLLs from 64-bit code using built-in IPC mechanisms. Originally published on DNJ Online, June 2007.

Can a 32 bit module be loaded into a 64 bit process?
However a 64-bit process cannot load a 32-bit module into its process space, and a 32-bit processes cannot load a 64-bit module into its process space. The only way that communication can happen between 32-bit and 64-bit modules is through interprocess communication (IPC).
How does WoW64 support 32 bit DLLs?
The WOW64 subsystem is in charge of supporting 32-bit modules on 64-bit Windows. To avoid unwanted collisions between 32-bit and 64-bit software, particularly when accessing the file system and registry, WOW64 isolates 32-bit modules using a process called redirection’ ( see MSDN reference ).
