Yes, it’s a noob question…

I have been using Dev-C++ for all my projects so far, but it is incredibly outdated, and so where the libraries. So I opened up my copy of Visual C++ and copied the code. When I compile, a million errors pop up, as if every second line of my code is shit. I would hate to start the project again from scratch.

Question: Why is it that Dev-C++ and VC++ compile differently??? I’ve heard they use different compilers, but its still C++. The first error I looked at was an invalid comparison between a const char* and a std::string.

Anyway, is there any way to make VC++ less strict on programming, as is Dev-C++. Or are there a few major differences between Dec-C++ and VC++ compilers that I should know about.

Most of the errors seem to be std::string related, or LPCWSTR (i can fix that myself).

Sorry about this very broad and useless topic, I’m knew.

    This will not answer everything, but it might help.

    By default, VC++ uses unicode while MinGW (on which DevCpp is based I believe) uses ansi.

    This might explain your issues regarding strings: you’re basically passing char* strings where most of the functions require something like wchar*.

    I suggest that either you fix your code so it becomes unicode compliant, or that you undefine the UNICODE macro in your VC++ project, if unicode is not required.

    As you stated, your old code was C++ and the code is C++ as well, so there shouldn’t be that much work… as long as you don’t rely on compiler specific behaviors.

    Could you give us some samples of things that go terribly wrong ? We might be able to help more accurately.
