CMD opening

Flu

Can somebody help me with this? I need to do this project fast, but it won't work like the example in the open() reference on the Processing site. So it says there that to write a command in the windows cmd, I first need to open it with open(cmd/c); and after that to put a string array consisting of one command or more to be executed in the cmd, but it simply doesn't work, and I don't get it why... can someone give me a test program consisting the command "ping www.google.com > test.txt" please? It just wouldn't work at me. The program executes, I press in the program window with my mouse ( the open() and the other instructions are found in void mousePressed() ) and when I check the test.txt, it doesn't appear anything but blank. Please, I really need this get working!

Yes. Show some code, dude.

void setup() {
  size(200, 200);
}

void draw() { 
 background(225);
}

void mousePressed() {
  String[] params = { 
    "cmd.exe", "ping wwww.google.com > test.txt"
  };
  open(params);
}

Is that windows?

It won't work in browser

What about /c

?

;-)

Flu

Yes, I am in windows, and I tried like a hundred options to write it in different ways, including this. I think I need to add that I put my program in the system32 folder in windows.

Flu

void setup() { size(200, 200); }

void draw() { background(0); }

void mousePressed() { String[] params = { "cmd.exe", "ping wwww.gogole.com > test.txt" }; open(params); }

Ok, the alignment is messed up but I think you can understand it, it's short and simple...

open() reference:

On Windows, the parameters are sent to the Windows shell via "cmd /c".

So the cmd.exe part is redundant. And you put too much info in one string, you must split it, as stated.

  String[] params = {
    "ping", "wwww.google.com"
  };
  open(params);

I don't recall exactly, but I don't think that redirection, pipes and the like work there.

you look here pls

Of course, you can make a little .cmd (or .bat) file that holds your command with redirection, and run it instead.

I Think I will go with the .bat file idea, sounds good. Thank you!
