    Is the executable the binary?

    Is the .exe version of your program called the binary??? I have heard people coin the term "Post your source and not the binary" but I wasn't sure if they meant the executable or not.

    I have visual studio and when I compile my program it generates all of these file types:
    .plg
    .dsw
    .opt
    .dsp
    .ncb

    These are generated for every program I compile, could someone fill me in on what they are used for????

    Thanks.

    Wow I have been asking a lot of questions laterly

    Yes. The *.exe is what they mean.

    If you want to make a .com file, you can create a .bat file (read up on make batch files if you dont know how) and use turbobat to make it into a .com file
    tudehopet uses Borland Compiler 5.5
    and Visual C++ 6.

    Even if you KNEW how to use a .com file, you probably wouldn't want to. Or, at least, not for anything constructive.

    .com specifies a different memory layout than .exe, at the ASM level. Which means to write a .com file, you either need a really small program, and a really old compiler, or just writing it in ASM.

    However, generally, because of size limitations, the only thing .com files are good at today is trojans, taking advantage of the .com endings of websites.

    Also, anything that your compiler generates is usually binary.

    If you can open it in notepad and get readable results, than it is not binary. This rule does not apply for MSVC resource files, however.

    Source is anything that is written by or indirectly by you. .c files .cpp files, .h files, resource files, and resource header files usually.

    thank for the info Imperito.

    so you say .com files are created using asm.

    so any suggestions on how to start asm programming, what all should i get to begin and if it is not too much hassle where can i get things for asm progs.

    >>the only thing .com files are good at today is trojans, taking advantage of the .com endings of websites.
    Heheheh. [lets keep that a secret now shall we]

    well also if i remember correctly in DOS shell .com files are executed before .exe files of the same name.

    if you have win98 (//edit: or below), use debug.
    Code:
    C:\>....
    
    debug
    - a 100
    mov ah,02
    mov dl,07
    int 21
    ret
    
    rcx
    (put whatever the address after the 'ret' command is minus 100. this time it's 7.)
    7
    n file.com
    w
    q
    and you have a com program that beeps at you

    here's the zip, just rename file.zip to file.com and execute

    note: it's 7 bytes long. it isn't a virus. (and even if it was (which it's not) 7 bytes is easy to review)
