I have a number of native C++ libraries (Win32, without MFC) compiling under Visual Studio 2005, and used in a number of solutions. I'd like to be able to choose to compile and link them as either static libraries or DLLs, depending on the needs of the particular solution in which I'm using them. What's the best way to do this? I've...
I'm in the process of implementing a binary tree in C++. Traditionally, I'd have a pointer to left and a pointer to right, but manual memory management typically ends in tears. Which leads me to my question... Are data structures an appropriate place to use shared_ptr? ...

I have a C++ application that uses the Win32 API for Windows, and I'm having a problem with GDI+ dithering, when I don't know why it should be. I have a custom control (custom window). When I receive the WM_PAINT message, I draw some Polygons using FillPolygon on a Graphics device. This Graphics device was created using the HDC from Beg...
I know this is about as bad as it gets for "religious" issues, as Jeff calls them. But I want to know why the people who disagree with me on this do so, and hear their justification for their horrific style. I googled for a while and couldn't find a style guide talking about this. So here's how I feel pointers (and references) should be...

Background: I'm currently debugging an application written over a custom-built GUI framework in C++. I've managed to pin down most bugs, but the bugs I'm having the most trouble with tend to have a common theme. All of them seem to be to do with the screen refreshing, redrawing or updating to match provided data. This is a pain to debug,...

According to the documentation, the handler should first be called with "UNICODE_NOCHAR", on which the handler should return TRUE if you...
I have a Windows application written in C++ that occasionally evaporates.

On the one occasion the crash occurred under the debugger, the debugger did not break---it showed the application s...
