Ok, I'm a newbie at this Windows programming, and I'm running into problems.
I'll have a lot more questions in the future, but for now:

[Linker Error] Unresolved external '_main' referenced from C:\PROGRAM
FILES\BORLAND\CBUILDER6\LIB\C0X32.OBJ

What does this mean, and how do I get rid of it?  I'm trying to make a
simple Win app.  It seems more trouble than its worth, but in the long run
it won't be.

You have a reference to something in C0X32.OBJ somewhere on your code...

c0X32 contains startup code (the stuff that's executed before your
main or WinMain).
In this case, I would guess you're linking with the version of the
startup code that calls main, when in fact your main entry point is
WinMain ().

There are a couple of ways to make a windows app in the IDE.

1. (Using the VCL) Use File->New->Application, or use
File->New->Other... and select Application.

2. (Without the VCL) Use File->New->Other..., select Console Wizard
and uncheck the "Console App" box. This should create a project
containing instructions to link the correct startup code for calling
WinMain (): in the .bpr file,
    ...
  <LINKER>
    <ALLOBJ value="c0w32.obj $(PACKAGES) $(OBJFILES)"/>
    ...

c0w32 is the correct version.

Best of luck.
