The MSDN documentation says that _findfirst returns -1 if it can't find
anything, instead of 0 (your client code may depend on that). See
http://msdn.microsoft.com/en-us/library/zyzxfzac(v=vs.71).aspx
Also, what does your _finddata_t look like? If it contains a fixed-size
char array for its "name" member, be aware that the "maximum sensible path
name" is a platform-dependent number. When I see the unguarded strcpy(),
I'd rather replace it with a strncpy instead.
Also, CString seems like a typedef for char*, but "normally" if it's a
class encapsulating a string (which its name suggests), you can't simply
cast it to a char*.
