• Visual C++ Autogenerated copy constructors and equals operators

  Hi everyone, Anyone know how to inhibit the compiler's autogeneration of copy constructors and equals operators for classes other than defining your own I have a template queue class for which cloning is not really a valid operation, and as such some of it's nested types are not suitable for auto-generated copy constructors/operators. Because of this, when I compile some code that uses the outer template class, I get compiler errors such as: error C2678: binary '=' : no operator found which takes a left-hand operand of type 'volatile T<itemtype>::NestedType' (or there is no acceptable conversion) When I double-click on the error, the editor simply goes to the end of the class declaration that has declared a member o ...Show All

• Visual C++ mysterious relinking

  Environment: In MSVC IDE 8.0, in a project that is not using .NET (but using MFC). I have a solution with a few different vcproj in it. If I hit F7, then they all build and link just fine. If I hit F7 again immediately, then one of the projects relinks. In fact, I can hit F7 repeatedly, and only this one project keeps relinking. Is there any way to get a "noisy compile", where I could get detailed info on what dependancies the IDE is looking at to decide a project is out of date If I could figure out which file is triggering it, I could probably figure out why. That's usually caused by either some outside application modifying / accessing some of the intermediate files. The most like ...Show All
