I'm trying to build a simple .Net wrapper around some basic C++ code. The C++ code does not rely on anything in the vcredist dlls, so I'm wondering if I can setup my project, so it doesn't require those dlls to work ?

I want to learn C++ for windows but have no idea where to start; there seem to be so many different technologies that have utterly confused me: Win32, MFC, ATL, STL etc. I know a good deal of C# and Java, no C and a small amount of ANSI C++ (datatypes, loops, classes and OOP), but when I look at other people's code or try to mess around ...
I found MSVCR90D.dll not found in debug mode with Visual C++ 2008 question but none of given answers really gives answer to the question.

I'd like to mention that my situati...
Okay, so I have a legacy Codebase and an old Visual C++ 6.0 Standard Installation CD. I want to install that on my Windows XP SP3 System. Is there anything I would need to avoid or to download besides SP6? Are executables created with VC6 compatible on Vista and Windows 7? (I know that there is no 64-Bit compiler, and that's fine) (I ...

I am developing for a SH4 based device that can run either CE 4.2 or CE 5.0. As per my previous question, I can target these devices using the Standard SDKs under embedded visual C++ 4.0, but I cannot debug over ActiveSync. I have also loaded Visual Studio 2008 (SP1), but cannot load these SDKs up, and hence cannot target my device. I...

I can't get double addition to work (even though compiler option /fp:strict which means "correct" floating point math is set in Visual Studio 2008). double a = 0.4; /* a: 0.40000000000000002, correct */ double b = 0.0 + 0.4; /* b: 0.40000000596046448, incorrect (0...

In the following case, _poly = poly; is copying the value of poly to _poly, or what? Thanks #include <iostream> #include <stdi...
