Thunking - Windows 7

Question

I am trying to write a very simple thunk that can be used from 16bit FoxPro to ultimately call a 64bit shiny WCF client.

I know I can't pass complex data types between them so I just want to pass a file name that data will be written to.

Problem is I can't even get the thunk to work. I am starting with

http://www.codeproject.com/Articles/29727/Generic-Thunk-of-Windows

but the call to

ghKernelDll = LoadLibrary("kernel.dll");

returns null. if i put kernel32 in there is it ok but that is to be expected - right? is it because I am running this application on my shiny 64 desktop? What do I need to be able to make this work?

Thank you!

Answer 1

Well, it might have something to do with the fact that 16-bit code doesn't run on 64-bit versions of Windows. In fact, to the best of my knowledge, kernel.dll doesn't even exist in 64-bit Windows.
