unresolved external '_main' referenced error
Author
Hi,
I'm new to window-programming, and I bought myself a book about games-programming.
It uses borland c++ to write games in Win32 API. I use borland c++ builder 3, and when i try to run the files, i get this error:
If your doing a Win32 (non-console) app, you'll need to use WinMain - not main - so that may be your problem. Could we see the code? That would help a lot.
[edit: Reading your post a second time, it sounds like your trying to run some code from a Win32 book. If that's the case, (I haven't used Borland C++) but make sure you compile it as a Win32 application - not a Win32 console application.]

Here are my codes:

I think you want the line that reads:
#include "Skeleton.rc"
in Unit1.cpp to read:
#include "Skeleton.h"
#include "Skeleton.rc"
in Unit1.cpp to read:
#include "Skeleton.h"
It appears that your project is configured as a command line program. The start up code contained in the cox32.obj file is trying to call your main() function, but you don't have one. Your code is for a Windows program, since you have a WinMain() function.
Check yor project settings and make sure that C++ Builder knows you are trying to build a Windows executable, not a command line executable.
