read the contents of ISO?

Omnimusha

HI, there is a library for reading the contents of a file, ISO?

Hi! :) Unfortunately I don't know.

Very often I see question about "is there a library to do X". Sometimes there is, but I wanted to point out that in case it doesn't exist, you have access to ALL the command line programs in your operating system. There are thousands, to do all kinds of things. Maybe you knew this already. But for those who don't, you can access any command line program from Processing like this:

import java.io.InputStreamReader;

try {
  Process p = Runtime.getRuntime().exec(new String[] {"ls", "-la"});
  p.waitFor();

  BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
  String line;
  while ( (line = input.readLine ()) != null) {
    println(line);
  }
  input.close();
} 
catch(Exception e) {
  println(e);
}

And if you don't care about the output of the program you can remove the import and the lines with "input".

This little program would call "ls", which lists the files in a folder, with the argument "-la", which shows more details about those files.

In your case, you could replace "ls" and "-la" by a command line program that does ISO file manipulations (for example to list the content of the ISO file, or to extract specific files). For instance, in Windows you could call this http://poweriso.com/tutorials/extract-iso-file-on-command-line.htm (I have never tried this, I don't know if it's any good).

HI, hamoid:

I tried what you said, from windows cmd, it works:

C:\Program Files\PowerISO>piso list d:\CD\ONLINE.iso /

---

from Processing, only managed to run the program, but I can not enter command

          Process p = Runtime.getRuntime().exec(new String[] {"C:\\Program Files\\PowerISO\\piso.exe", "list"});

        Type piso -? for help

Bad parameter: list

HI dimkir:

I do not understand how it works, or how to install these libraries, you have worked with these libraries? example plz

Omnimusha

String cmdArray[]={"C:\\Program Files\\PowerISO//piso","list","D:\\CD\\ONLINE.iso","/"};
  Process p = Runtime.getRuntime().exec(cmdArray);

the problem is the last parameter, I do not recognize it, it does nothing "/"

Omnimusha

LOl..........work!!!!!!!

delete this line p.waitFor();

import java.io.InputStreamReader;

try {

 String cmdArray[]={"C:\\Program Files\\PowerISO//piso","list","D:\\CD\\ONLINE.iso","/"};
 Process p = Runtime.getRuntime().exec(cmdArray);
 BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));

  String line;
  while ( (line = input.readLine ()) != null) {
    println(line);
  }
  input.close();
}
catch(Exception e) {
  println(e);
}

Awesome :) Since it's working, you can mark the question as answered in this forum. Cheers!
