    Eject a cd with C++ code

    Hi.
    I want to try to open my cd drive with a C++ code, I searched on this forum and found something but it isn't working (Trying to eject D drive using code, but not working... :(. I got 3 questions; (please look at that thread) it sais: "insure to include the winmm.lib in the links tab of the project settings".
    1. What is "winmm.lib"?
    2. What does that bold line means, and what do you need to do?
    3. Do you also got to "include" it with "PlaySound()"?

    Now on the end of that thread you see a new code but it isn't working.
    I have a couple of questions on that to:
    1. Do I need to "include the winmm.lib in the links tab of the project settings"?
    2. How do I "include the winmm.lib in the links tab of the project settings"?
    3. Does that code opens a cd drive?
    4. How can I eject a cd with C++ code?
    Thanks for any help.

    You can use SDL library for work with CD-ROM and other multimedia stuff...

    That is in C and doesn't really seem to work. I need some sort of SDL.h.

    The word rap as it applies to music is the result of a peculiar phonological rule which has stripped the word of its initial voiceless velar stop.

    Here's C++ code, which works perfectly in DevC++ (you can found SDL on one of updates servers) - but you must copy $DEVCPP/bin/SDL.dll to directory where you have this code...:

    PHP Code:
    #include <SDL/SDL.h>
    #include <windows.h>
    #include <iostream>
    using namespace std
    int main(int argcchar *argv[])
    {
     
    SDL_Init(SDL_INIT_CDROM);
     
    atexit(SDL_Quit);
     
    SDL_CD *handle;
     
    handle SDL_CDOpen(0);
     
    SDL_CDEject(handle);
     
    SDL_CDClose(handle);
     
     return 
    0;

    Code:
    #include <windows.h>
    
    int main(int argc, char *argv[])
    {
        mciSendString("set cdaudio door open wait", NULL, 0, 0);
        return 0;
    }
    That opens drive D: on my computer using the mciSendString function. Yes, you must link winmm.lib into your project to do this. On DevC++, to link a library into your project, you open Project => Project Options... => Parameters tab => In the linker options box add -lwinmm. In VC++ you go to Project => Settings... => Link tab => Objects/libraries box => winmm.lib. Other: look at the compiler doc's.

    (To Tonto)Thanks, but I do need to create a Project of it.
    Now I have 2 questions:
    1. Is there a way to "include" winmm.lib without using a project file?
    2. This opens my D drive, can I also open my E drive?
