I know this is off topic but I haven't been able to get help anywhere else.
I would like my program to execute (via Runtime.exec or some other mechanism) a
command that is typed into a TextField. Anything that might be
executed from a System prompt should also work from my program. Below is
the program code. It successfully executes instructions such as
"C:\WINNT\Notepad.exe"
and
"Notepad"
but not
"C:WINNT\SYSTEM32\cmd.exe C:\my.bat"
or even
"C:WINNT\SYSTEM32\cmd.exe C:\WINNT\Notepad.exe".
No exceptions are generated.
import java.awt.*;
import java.awt.event.*;
import java.io.*;
public class Executor extends Frame{
public static void main( String[] arg ){
new Executor();
}
public Executor(){
setLayout( new GridLayout( 0, 1 ) );
final TextField field = new TextField();
add( field );
Button b = new Button( "Execute" );
b.addActionListener( new ActionListener(){
public void actionPerformed( ActionEvent e ){
try{
Runtime.getRuntime().exec( field.getText() );
}catch( IOException ex ){
ex.printStackTrace();
}
}
});
add( b );
pack();
setVisible( true );
}
}
