I found this post on Experts exchange about C++ name mangling hell. I have run in to this problems a few times, it drives me nuts as I always forget about it when trying to use LoadLibrary and GetProcAddress. #ifdef FIRSTINDLL_EXPORTS #define FIRSTINDLL_API extern “C” __declspec(dllexport) #else #define FIRSTINDLL_API extern “C” __declspec(dllimport) #endif // Exported [...]

I got asked how to create a simple averaging class. If you where feeling smart you could enhance this class in to a template class for a object that has the =,+,>,< operator. But I’m feeling lazy today. class CMinMaxAvg { private : int m_count; int m_total; int m_min; int m_max; public: CMinMaxAvg() { m_count [...]
I create a lot of windows application to make things easier for my customers. The simple act of coping a file from an email to a certain directory can become the most complicated tasks for a certain type of customer. I use an Scriptable Install System provided by NullSoft called NSIS (Nullsoft Scriptable Install System). [...]
I’m often surprised how many times this question has come up by beginner programmers. How do you tell the size of a file in win32? This method will fail on files greater then 4GB, and its slower then other methods but it quick and easy as long as you are not dealing with files greater [...]
