I'm using VC++ 6.0
I'd like to access mp3 tags and change things like song title, artist, etc..

I found this library which does what i need:
https://sourceforge.net/projects/id3lib/

I downloaded the library and followed the instructions about using it, but I always get the same error of "id3/tag.h" not found.

I'm pretty new to VC, I must be missing something. I'd really appreciate it if you took a look at this library and helped me get it to work in my project, I've been messing with it for almost a week now.
What are the exact steps I need to do in VC 6.0 to use this library?

One more little thing that i don't understand is how this header I'm trying to use is made. It's not in the ID3LIB files I downloaded, so it is built somehow on the way. maybe someone can enlighten me and tell me how it works.

Thanks a lot

Put the files in the include folder supplied into your Visual Studio include folder. This is, most likely, at Visual Studio Path\include.

I can't find such folder.
The library I downloaded has a project in it that uses this library, yet I can't find out what settings differ between this project and mine.
The files of this library are scattered all around in its folder, there's some text file with directions which I followed but it didn't help.
You could take a look at that library via that link i posted at the beginning, that would clarify things a bit.

Haven't got an answer to your question, but i'd like to strongly recommend the use of TagLib instead of id3lib. TagLib is much faster (6 times faster, according the homepage) and with a much cleaner, object-orientated API.

Thanks a lot, that is much better.
would you mind telling me how do I use it in my Visual C++ 6 project?

You have 2 options:

1) Do #include "blah/blah.h" instead of #include <blah/blah.h>
2) Copy the files for the library to your visual studio path\vc98\include folder

Thanks a lot guys

wops, I get tons of errors within the library files.
things like "long long is illegal" missing ;s

could it be VC's fault?

Please post the code that is causing the problems, and then also post the compile log so that we can see exactly what is going on. Although, it sounds to me like you forgot to include the actual library (*.dll) in your project. If you didn't do that, or don't know how, google for it.

i get the errors on a simple: TagLib::ID3v2::Tag t;
I can't find any *.dll files in the project's folder

I get 102 error for that, here's some of them:
