When compiling I got this error:

frac.obj(frac)
 Error 42: Symbol Undefined _DeleteDC@4
frac.obj(frac)
 Error 42: Symbol Undefined _BitBlt@36
frac.obj(frac)
 Error 42: Symbol Undefined _SetPixel@16
frac.obj(frac)
 Error 42: Symbol Undefined _CreateCompatibleDC@4

--- errorlevel 4

Now what I'd like to know is what does it mean and how do I fix it?

thanks,
Phil

I think you need to add USER32.LIB to your link command line.
