Command Line compiling API and MFC programs

[Dr. Laurence Leff]

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__Dispatc hMessageA4

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.

Yes. You have to tell the compiler the libraries you need.

If you read your compiler documentation, you will find the
name.

It is better when starting, to use the IDE provided by Microsoft
because it gives access to the documentation. For each function
the doc tells you which library is needed.

Besides, it shields the novice programmer from many complexities.

Load your program in the editor, and type F1 at the name
you want to investigate. Then, if the installation went OK,
the help system will display you the doc of that function.

I would ask further questions in the many support groups of the
compiler in the net.

This is all very Windows MSVC specific and thus off topic in
comp.lang.c, it belongs somewhere in one of the MS specific news groups.
