How to use Windows DISKPART tool by code / java or c++;

[SirPaul]

Hi guys,

 

please, can anyone help me ? 

 

I am having this wierd problem. I want to use DISKPART which is tool in windows used to manage partitions e.t.c. of your drives, from java, programatically.

The problem is , how to open DISKPART and insert command "select disk 1" and then "clean". (example);

 

Problem comes when DISKPART is opened from java in new window, and seems no to accept any other commannds.

 

Here's the code.

	 ProcessBuilder builder = new ProcessBuilder(			            "cmd.exe","/C diskpart /s select disk 1", "clean");			        builder.redirectErrorStream(true);			        Process p = builder.start();			        BufferedReader r = new BufferedReader(new InputStreamReader(p.getInputStream()));			        String line;			        while (true) {			            line = r.readLine();			            if (line == null) { break; }			            System.out.println(line);			        }			    }

I tried multiple ways, this is the default way. Thanks a lot

If you wanted to use diskpart, why are you trying to start cmd? This is what I would do (if your parameter syntax is correct):

ProcessBuilder builder = new ProcessBuilder(			            "diskpart.exe","select disk 1", "clean");

When you type diskpart in a cmd shell, you are telling cmd.exe to execute diskpart.exe and hookup stdin and stdout (from what I can tell, I don't really use this tool often). So I am pretty sure this should work for you.
