  • "Layered" precompiled headers

    Last post by Simple Samples
      • Hi, I'm reading the book "C++ templates, the complete guide", and in section 6.5 the writers suggest to use layered precompiled headers. With that they mean to have multiple precompiled headers, but also to have a precompiled header to use another precompiled header, as if it inherits the other precompiled header. For instance, have one header containing all std includes like vecto

      • Hello, I recently installed Visual Studio 2005 and noticed that when I make a C++ Win32 Application (even a simple "Hello World" application) it doesn't run on a computer without the framework installed. It simply displays a message saying that the configuration of the application is incorrect (or something similar), which is normal, given the fact that it needs the framework installed t

      • Hi, I am having a big problem using Visual C++ 2005 SP1. IntelliSense works awful, I barely get some IntelliSense now and then. Before, when using Visual C++ 2003 and 2005 without SP1, it worked beautifully. If I added a member to a class, it was immediately intellisense-visible in the class functions. In SP1, I add a member and it is not visible for a very long time. Also, the current v

      • Hi ! Consider a pointer class Ptr<T> behaving like a pointer. Is the result of the following code completely defined or is it compiler dependent Ptr<T> p = some_valid_address; *p++ = 2 * *p; I ask this because VC++ 8 gives me different results depending on whether I compile with no optimizations (/Od) or full optimizations (/Ox). /Od seems to generate something like: *p = 2* *p;
