I'm trying to write a short windows application, and I need to define a windows
class object. In C this is simple since the class is defined in the windows
header file. Unfortunately, I can't create a wc object in my D program. I tried
importing the header file, but the class definition doesn't carry over into the
program's namespace. Moreover, this is just part of a larger problem. I have
been experiencing problems importing user defined data types from C header files
in general. If someone could explain how D interfaces with C code, I would
really appreciate it.
Thanks

Interfacing with C, and interfacing with C source code are two different things. This might help you: http://www.digitalmars.com/d/interfaceToC.html

thanks for the reference.

Unfortunately when I tried to compile it the debugger flaged several errors in
the resulting obj file. Each of these errors involved undefined Symbols. For
example The first error reads;
'winsamp.obj(winsamp)
error 42: Symbol Undefined _SelectObject@8'

I moved a copy of winsamp.d into the same directory as dmd.exe, and I tried
compiling it with the line ;
'dmd winsamp.d'

Is there anything wrong with the source code. Or did I compile it wrong?

Try:  dmd winsamp.d gdi32.lib

Ok. The sentence "importing user defined data types from C header files" led me to that conclusion.
