I experience the following problem while using legacy VC6. I just cann't switch to modern compiler, as I am working on a legacy code base. http://support.microsoft.com/kb/172396 Since there are no way to export map, my planned workaround is using static linking instead of dynamic linking. I was wondering whether you all had encountere...

My native C++ COM component uses ATL. In DllRegisterServer() I call CComModule::RegisterServer(): STDAPI DllRegisterServer() { return _Module.RegisterServer(FALSE); // <<< notice FALSE here } FALSE is passed to indicate to not register the type library. ATL is available as sources, so I in fact compile the implementation of CComM...
I have a class which is essentially just holds a bunch of constant definitions used through my application. For some reason though, longs compile but floats do not: class MY_CONSTS { public : static const long LONG_CONST = 1; // Compiles static const float FLOAT_CONST = 0.001f; // C2864 }; Gives the following error: 1...
Hello everyone! I'm currently developing a custom control that derives from CStatic MFC class (Smart Device C++ project). I have created the control class using VC++ MFC class wizard, selecting CStatic class as its base class.

I need to write an application using MPICH2 (64 bit, in case you're wondering). A GUI is entirely optional but would of course be a huge plus. Will mpiexec have any difficulties running managed VC++ code? Are there any other problems I might run into with compiling/linking (calling conventions, etc)? Just to give you an idea, the genera...

Dear developers, I have an application that requires Microsoft VC++ 2005 (SP1) Redistributable Package. I know that I can just download it and install it. The problem is, in our server, there is Microsoft VC++ 2008 (SP1) Redistributable Package already installed. Now, do I still need to install the 2005 (SP1) version? Or the 2008 (...
Hi, I've run into an issue porting a codebase from linux (gcc) to windows (msvc). It seems like the C99 function vsscanf isn't available and has no obvious replacement. I've read about a solution using the internal function _input_l and linking statically to the crt runtime, but unfortunately I cannot link statically since it would mess...

I still feel a bit unsafe about the topic and hope you folks can help me - For passing data (configuration or results) between a worker thread polling something and a controlling thread interested in the most recent data, I've ended up using more or less the following pattern repeatedly: Mutex m; tData * stage; // temporary, ac...

On certain error cases ATL invokes AtlThrow() which is implemented as ATL::AtlThrowImpl() which in turn throws CAtlException. The latter is not very good - CAtlException is not even derived from std::exception and also we use our own exceptions hierarchy and now we will have to catch CAtlException separately here and there which is lots ...
