Question, How to write key value using ProcessBuilder?

[hoon kim]

Hi~~~
I have a question about ProcessBuilder.

I try to control MS-DOS program.

The program name is CARI-6M.

You can download http://www.faa.gov/data_research/research/med_humanfacs/aeromedical/radiobiology/cari6m/ .

The CARI-6M has text GUI environment.

I don't know to write key "1" using OutputStream.

The writing method does not run on windows 7.

please help me~~~~~!!~~.

 ProcessBuilder cari=new ProcessBuilder("C:\\cari6mex\\CARI-6M.EXE");
		ProcessBuilder cari=new ProcessBuilder("cmd","/c","D:\\hoon\\stsWorkSpace\\CosmicRay\\CosmicRay\\CARI-6M\\CARI-6M.EXE");
		cari.directory(new File("D:\\hoon\\stsWorkSpace\\CosmicRay\\CosmicRay\\CARI-6M\\"));
		Process cariP=cari.start();
		
		String ls_str;
		
		try
		{
			BufferedReader inputStream=new BufferedReader(new InputStreamReader(cariP.getInputStream()));
			BufferedWriter outputStream=new BufferedWriter(new OutputStreamWriter(cariP.getOutputStream()));
			
			while(true)
			{
				if((ls_str=inputStream.readLine()) != null)
				{
					System.out.println(ls_str);
				}
				else
				{
					System.out.println("Input key 1 enter");
					char[] menu1={0x01,'\r'};
					outputStream.write(menu1); //This line didn't work. 
				}
				
			}
			
		}
		catch(IOException e)
		{
			e.printStackTrace();
			System.exit(1);
		}
		System.out.println("try exit");
		cariP.destroy();

You can't write to GUI text fields using Process streams.
You might want to look at the Robot class to see if that is a better solution to your problem.

Welcome to the Ranch,

Can you explain exactly what you are trying to do and what doesn't work. Does it not compile, not run, run but not do what you want (if so what does it do) etc.

Sorry I'm not good at English. I'm Korean.
I'm trying to get cosmic ray dose using the CARI-6M program.
The CARI-6M is MS-DOS program has text GUI.
I want to input keys instead of human's typing on background process.
Could you advise some solution?
I modified the source.

Don't worry, your English is a lot better than my Korean.

text GUI doesn't really make sense, it is either a text based CLI (Command Line Interface) or a GUI (Graphical User Interface). I guess you mean CLI as it's a MS-DOS program.

I suggest you add lots of print statements in your code so you can see what lines are running and where it is getting stuck. You might want to look at the way readLine() works - what happens if it blocks waiting for input.

Using Process is more difficult than you might think. There are a number of things you have to be aware of, I suggest you read http://www.javaworld.com/article/2071275/core-java/when-runtime-exec---won-t.html.

Dear Tony Docherty,
I am so sorry. Currently I also run the CARI-6M to calculate radiation dose and I found his question through googling. I just want to communicate with him in our mother tongue. If my post disturb your policy, would you please accept my appology.
Best regards,

I have succeeded to control the CARI-6M using WIN32 API.
It's very difficult mission.

[Tony Docherty]

Congratulations.
Would you like to post your solution so other may also benefit from it.

[Francesco Cataudella]

I am having the same problems: integrate CARI6-M inside an application.
I tried using java but with the same results.
I tried using autohotkeys but it is not stable.

Thanks
