Perhaps:

1. open("cmd.exe myfile.bat");

or

1. try {
2.       String line;
3.       OutputStream stdin = null;
4.       Process p = Runtime.getRuntime().exec(new String[] {
5.         "cmd.exe", "myfile.bat"
6.       }
7.       );
8.       BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
9.       while ((line = input.readLine()) != null) {
10.       }
11.       input.close();
12.     }

       Try to be and still can not work. Please help me.

        My new code    // Does not work.

1. void draw(){}
2. void mousePressed()
3. {
4.   if(mouseButton == LEFT){
5.   try {
6.   String line;
7.  
8.   OutputStream stdin = null;
9.  
10.   Process p = Runtime.getRuntime().exec(new String[] {
11.          "cmd.exe","myfile.bat"});
12.    
13.   BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
14.  
15.   while ((line = input.readLine()) != null) {
16.     println(line);
17.   }
18.     input.close();
19. } catch (Exception err) {
20.   err.printStackTrace();
21. }
22. exit();}
23. if(mouseButton == RIGHT){
24. open("cmd.exe myfile.bat");}
25. }

        myfile.bat

1. @echo test
   @echo open
   @echo on
   @echo dos
   @echo off
   notepad.exe

  Then open the program.
 Have a message but does not work as it is written is inactive.
 myfile.bat.

 


  But if the notepad.exe with this work.

1.   open("notepad.exe mytext.txt")

 

Objectives that I want to do is create a program.  Arduino Windows command line build controls .
http://www.arduino.cc/playground/Code/WindowsCommandLine

This is a sample program that I am trying to develop the Spansion.




Please help me. Thank you very much......

Running on a mac.. so it's hard for me to test.
You could try to use the cmd.exe with the " /c" option.

Here is another approach.

1. open("rundll32 SHELL32.DLL,ShellExec_RunDLL " + "file.bat");

Hi,

I have the same issue here with trying to get Porcessing to launch a .bat or the .exe I compiled.

I am using Windows 7 Ultimate and Processing 1.5.1 I have also completed all the following methods on 1.2.
Currently installed java updates are 1.6.0_25 and 1.6.0_26.

Project aim is to take RFiD tag reads and use the Tag ID (tounchatag library) to start a batch file. The .bat is a simple menu at the moment.

The strange thing is that this has previously worked, when I started out on this little project it worked using a full path method then when I came back to it over the weekend nothing would launch the .bat/.exe file.

Why does the problem exist and can anyone help me solve my issue.

I have no problem launching notepad which pops up straight away using the full path open() method. Methods tested so far, this doesn't include all the processing code just the final couple.

1. void drawTags(String[] tagList, int pos) {
     for (int i = 0; i < tagList.length; i++) {
       text(tagList[i], (pos + 1) * 100, (i * 10) + 200);
       println(tagList);
         launchapp(tagList[i])  ;
       }
    }
   //launchapp to run the string parameters and launch the program
    void launchapp(String tag) {
    //if (tag.equals("04c72ab9232580") )
      //open("C:/Windows/system32/notepad.exe"); This used as a test
     //else
    //text("Incorrect Tag to Launch App", x, 255);
2. 
   
3. // First Method - Failed
   if (tag.equals("040443b9b20281") )
     open("cmd /c C:/Users/ali/Documents/Processing/APP_to_Launch_RFiD1/xbmc.bat");
        else
   text("Incorrect Tag to Launch App", x, 255);
      }
4. // // Second Method - Failed
   
5. if (tag.equals("040443b9b20281") )
     open(" C:/Users/ali/Documents/Processing/APP_to_Launch_RFiD1/xbmc.bat");
        else
   text("Incorrect Tag to Launch App", x, 255);
      }
6. // Third Method - Failed also tested without "+"
   
7. if (tag.equals("040443b9b20281") )
   
8. open("rundll32 SHELL32.DLL,ShellExec_RunDLL" + "C:/Users/ali/Documents/Processing/APP_to_Launch_RFiD1/xbmc.bat");
9. else
   text("Incorrect Tag to Launch App", x, 255);
      }
10. // Fourth Method - Failed
      String[] params = { "C:/Users/ali/Documents/Processing/APP_to_Launch_RFiD1/xbmc.bat " };
      open(params);
      println(params);
    
    

I am going a little bit crazy trying to work out what is stopping this from running and why is has previously worked just using the full path.

Many Thanks in advance for some support here

Just tested open("H:/Temp/test.cmd"); and p = open(new String[] { "cmd", "/c", "H:/Temp/test.cmd" }); and they both work for me with Windows 7.
Note: I first wrote in the .cmd file copy x.txt y.txt, the files being in the same folder as command file. But I found out that Java doesn't run it with the current dir set to this folder, so the command failed. With absolute paths, it worked.
I also found a trick to see the command window after running the command. That's how I saw the error message, otherwise it just silently fails, which is hard to distinguish from not running at all...
p = open(new String[] { "cmd", "/c", "start", "/w", "H:/Temp/test.cmd" });

No idea. It might depend on what is in your command file...

I have a very similar issue with open(). Even though this thread have been a great help, especially thanks to PhiLho, I just can't seem to be able to open a bat file that is not in the same folder as my pde file or data folder. Even with PhiLho's technique I just manage to open the cmd.exe, but it's empty, the code being for exemple

open(new String[] { "cmd", "/c", "start", "/w", "C:/program files/program/test.bat" }), with this I get the empty cmd.exe, even the adress shown in it is not "C:/program files/program/>" where my bat is located but "C:/users/admin/processing/test/", the later being the adress where my pde file is located.

Also I would really appreciate if someone could explain to me all the different arguments that can be used with the open() function. Like the ones used in this thread "/c", "start", "/w" .

Thanks in advance.

Well, when I run my command on an unsaved sketch, the command line opens in C:\Java\processing-1.5.1, ie. where I installed Processing. That's on Windows 7. My .cmd file is effectively run. Its content is just:
copy H:\Temp\Test.scala H:\Temp\Y.todelete
ie. it acts on a folder which is not the current folder.
Not sure why your batch file isn't run.

" explain to me all the different arguments that can be used with the open() function"
On Windows, type cmd /? or start /?
These are Windows commands, not Processing ones.

Many thanks for your reply, but I just can't seem to make it work. My hole purpose is to open a .bat file remotely with Processing or PHP. But the two can't apparently do it. (I'm using the exec() function with PHP, I even tried system()).

Is there some kind of special authorisation I need to enable in the softwares so it can run .bat files, or is it something else ?

Here is the code I use (I have tried all the lines that are in the //):

void setup() {
  size(200, 200);
}

void draw() {
 
}

void mousePressed() {
  //open(new String[] { "cmd", "/c", "start", "/w", "C:/Program Files/Blender Foundation/Blender/test.bat" });
  //open("C:/Program Files/Blender Foundation/Blender/test.bat");
  open(new String[] { "C:/Program Files/Blender Foundation/Blender/test.bat" });
  //open(new String[] { "cmd", "/c", "C:/Program Files/Blender Foundation/Blender/test.bat" });
  //Runtime.getRuntime().exec("cp Program Files/Blender Foundation/Blender.exe");
}

Just managed to open the files with PHP. I still can't do it with Processing but PHP is ok too.
 Anyway many thanks for your help and your time. I will  try to make work some other time.

Try:
open(new String[] { "cmd", "/c", "start", "/w", "\"C:/Program Files/Blender Foundation/Blender/test.bat\"" });
perhaps.
Or try with a path without spaces.
