i learn about the code hellosp written by douglas boling ,when i build it
,some error
happened.
the error is :

below is the hellosp.cpp.

There are a few bugs in this code :-(, but feel free to ask as you come
accross them.

The bug you have is in the hellosp.h file, you should have a line like this:
#define dim(x) (sizeof(x) / sizeof(x[0]))
to get that error it might (incorrectly) be this:
#define dim(x) (sizeof(x) / sizeof(x0))
so just add those square brackets back in and that should get it going
again.

tks. very useful. there is an error in hellosp.h
like this :
#define dim(x) (sizeof(x0)/sizeof(x[0]))
~~~
I just looking for the error in the file Hellosp.cpp ,so can't find it .

thank you very much.

Are you using this:
http://msdn.microsoft.com/library/d...Application.asp

if you are then you should have three files, hellosp.cpp, hellosp.h and
hellosp.rc. The line to check is in hellosp.h, NOT hellosp.cpp
