How does not compile a Windows API and a Windows MFC program from the
command line with Visual.net. (I can do the former, at least, with Visual
Studio by creating a "Win32 Project.")

However, I tried the same thing on the command line.
(In the days of Visual C++ 4.0 through Visual C++ 6.0, I had some
make files and stuff that did this.

So, I typed CL hellowin.C

There were no compile time erors; only errors from the linker
such as error LNK2019: unreasolved external symbol
___imp__DispatchMessageA4

I got similar errors from other basic Windows API functions such
as Show Window, DrawText and BeginPaint.

So I believe that I need to know what libraries are needed and how to
specify these. The "CL" command does not accept the "/LIBRARY" option
from Visual C++ 4.0

Thanks for any help that can be provided.
