c++ - Enable a single warning in Visual Studio

Question

Is there a compiler switch to enable a single warning in Visual Studio?

The reason I ask is I want to enable warning C4265 which is off by default. My searching has only turned up ways to turn warnings off.

Even Microsoft pages called How to: Enable or Disable Compiler Warnings still only mention disabling.

Answer 1

#pragma warning(default:4265)

It might seem like that would set the warning to it's default setting(which would be disabled), but that's not the case. It turns it on.

You can also do this:

#pragma warning(X:4265)
// where X is the warning level(1,2,3 or 4) that you want this warning to be generated at
