C++ provides a syntax for checked exceptions, for example: void G() throw(Exception); void f() throw(); However, the Visual C++ compiler doesn't check them; the throw flag is simply ignored. In my opinion, this renders the exception feature unusable. So my question is: is there a way to make the compiler check whether exceptions are c...
We have a large C++ application, which sometimes we need to run as a debug build in order to investigate bugs. The debug build is much much slower than the release build, to the point of being almost unusable. What tricks are available for making MSVC Debug builds execute faster without sacrificing too much on the debugability? ...

I'm currently designing my first ever GUI for Windows. I'm using MFC and Visual Studio 2008. The monitor I have been designing my program on has 1680x1050 native resolution. If I compile and send my program to one of my coworkers to run on their computer (generally a laptop running at 1024x768), my program will not fit on their screen. ...
Does every file need to #include "stdafx.h" when using precompiled headers? Or do only source files need to include it. EDIT: Also, my precompiled header file #includes a lot of STL headers. But, in my headers, I sometimes have functions that return std::vector or something like that, so I need to #include <vector> anyway. Is this worse...

I'm working on a project that uses a lot of generated files for a GUI. After some recent updates, I get this error. If I remove some controls (the new ones or some old ones, doesn't seem to matter which), the error goes away. I've temporarily worked around the problem, but I'd like a more permanent solution. I've seen mentioned on th...
I'm trying to test out a library that provides a VC++ example; however, I use gcc/g++ for all of my projects. Well, the way the VC++ example accesses the library is it uses the #import directive, passing the location of the library DLL, then it does a using namespace LIBRARYNAME, and then it's able to create some undefined type (I'd ass...
