C + + "sprintf_s": not a member of "' Global Namespace '"

Recently copied some code into the DLL project from another console project, after compiling an error, prompt: C + + "sprintf_s": Not "' Global namespace '" member,

After checking, it was found that the copied code contained the Std::cout << "..." Guessing DLL engineering does not support such a compilation, and the compilation succeeds after deletion.

There is a topic on http://stackoverflow.com/questions/3710168/how-do-i-build-notepad-with-visual-c-2010-express to discuss this error, Please refer to.
