I tried some time ago to compile a lib with WinMain that expected and external
DFC_main ... but it all failed ... the linker seems to expect Main/WinMain to be
in an object file not one of the included libs.

I get that Access Violation lots if I add/remove a member from an included d
file that is in a lib, but forget to recompile the lib (the depends in my make
file do not cover imports)

check that you are not compiling the lib as debug and the main as release
its late and I'm going to bed soon, but here is the examples from my make file

DMD=c:/dmd/bin/dmd.exe
DMC=c:/dm/bin/dmc.exe

Walter can we get a definitive 'no that is in no way possible', or a 'yes

Actually it seems to work now , i had a static constructor that was
assigning a value to a static member of another class, i moved that into its
own static constructor and somehow it seems to work ( using a WinMain in a
lib, having the user link in an object file ) .

Im creating some docs right now, only bad thing about the lib is manual
placement ( ye old grid system ) of the controls , which I dont think will
be a problem given a good resizing system and dialog editor ( using native
code none of that .rc crap ).

Im putting it up at http://www.atari-soldiers.com/gpage.html1.html .

Its very easy to use and even easier to extend, everything's just a Window
so you can do whatever you like, and with some manipulation you can even
create floating controls on the desktop .

P.S. its not complete, im still wrapping some of the controls but expect a
usable version within a week or so.  Could anyone reading this download it
and report build problems ?

Thanks

Isn't the existence of a WinMain a Windows specific thing? I mean,
it may not be at all possible to _have_ a WinMain in a dll?

I'm no guru at this, but what if you told the library users to have
an otherwise empty WinMain that just calls AtariSoldiersDllMain?
