[Jherald Lacambra]

how can i run this block from platforms lower than windows 2000

b1.addActionListener(new ActionListener(){
public void actionPerformed( ActionEvent evt){
txt.setText("Quotation Processing");
Process cmd;
Runtime launch = Runtime.getRuntime();
try{
cmd = launch.exec(new String[] {"cmd.exe", "/c", "chapter1.chm"});
} catch (Exception e) {
System.out.println(e);
cmd = null;
}

Try command.com instead of cmd.exe:

You can use "command.com", but you cannot use filenames bigger than 8.3

ihave tried this:

b1.addActionListener(new ActionListener(){
public void actionPerformed( ActionEvent evt){
txt.setText("Quotation Processing");
Process cmd;
Runtime launch = Runtime.getRuntime();
try{
cmd = launch.exec(new String[] {"cmd.exe", "/c", "chapter1.chm"});
cmd = launch.exec(new String[] {"command.exe", "/c", "chapter1.chm"});
} catch (Exception e) {
System.out.println(e);
cmd = null;
}
};
});

The program is running but there is an error
java.io.IOException: CreateProcess: command.exe /c chapter1.chm error=2

Note that both Stephen Huey and I said to use command.com rather than command.exe

i tried this one

b1.addActionListener(new ActionListener(){
public void actionPerformed( ActionEvent evt){
txt.setText("Quotation Processing");
Process cmd;
Runtime launch = Runtime.getRuntime();
try{
cmd = launch.exec(new String[] {"command.com", "/c", "chapter1.chm"});
} catch (Exception e) {
System.out.println(e);
cmd = null;
}
};
});

but there is a popup:

C:\winnt\system32\command.com
c:\winnt\system32\AUTOEXEC.NT. The sytem file is not suitable for running MS-DOS and Microsoft applications.
