Basic question about string class for C++ .NET

I want to use a string class which does not require any additional DLLs, so that the exe I compile can run on a clean build win95 box simply by copying the exe. Whenever I try to use string, String or CString in C++ it seems to require additional components. When I added mscorlib.dll (.net framework) it was ok. What I need is a string class which does not need .net framework. I also need a registry class and some classes for handling arrays would be nice.

I found a few string classes on the web but who can you trust ?

Main things I need are things like split, join, replace etc etc functionality

Would be nice if my resulting code remained compiler independent but its OK to lock into win32 platforms.

Full points for a solution that gets me bug free string class and a registry class which works without external dlls (kernel, user advapi etc are acceptable)

I would suggest that you use the standard classes and Standard Template Library classes provided standard with most C++ compiler. A word of warning: any MS C++ compiler does not support the full definition of the C++ language.

For verification purposes, using GCC is a good idea! GCC can be downloaded for free at
   http://www.gnu.org/directory/devel/compilers/gcc.html

It seems to me however that you're linking to the .NET framework, instead of to the crt (c runtime). Have a look at your linker settings in your project, make sure that you're not linking to the .NET runtime.

Arguments above are also true for accessing the registry. I don't think that there is a class abstraction for the registry, however the API calls are easy to follow.

You want to use .NET framework without .NET framework installed?

Be sure to check projects settings to use the non DLL version of the C run time library. At least in VC6 you had the option between single threaded, multi threaded and multi threaded DLL. The last needs then DLLs to be copied with the project, whereas the others don't.

Definitely a beginner to VC, .NET and C++, but on a mission to get 10k lines of vb rewritten to C++ in a few days!

I'm just using the .NET compiler because its already installed. It seems to be similar to VC6 and I can write simple hello world programs which will run on win95 with only copying the exe (no dlls or .net framework). I just need to be able to use string classes etc and hopefully a registry class (apis are fine, wrappers would be nice), and still be able to install on win95 just by copying the exe.

Don't want to use the .net framework - just want an exe that works on its own, don't care if I have to use .net or vc6, they seem similar to me!

Checked the project settings and can't really see anything for C run time library, the MFC setting is "Use Standard Windows Libraries".

I would recommend that you have a look at the compiler and linker settings for the simple Hello World sample project and mimic those settings in your own project.

I have been unable to find a hello world sample which uses a string class and does not require a dll. Thats definitely all i need
