• Matthew Weyland _CRT_SECURE_NO_DEPRECATE has no effect

  MSDN clearly states that if you define _CRT_SECURE_NO_DEPRECATE it "will disable deprecation warnings".

The only way to disable the warning, as far as I can tell, is to use #pragma warning (disable:4996) or add the warning to the C/C++ settings (Ad ...Show All
