What does this error mean??

[Patrick ODonnell]

Hi,
I am trying to run the following peice of code but it is giving me the following runtime error:
java.io.IOException: CreateProcess: dir error=2
try
{
// Execute command
String command = "dir";
Process child = Runtime.getRuntime().exe(command);

// Get input stream to read from it
InputStream in = child.getInputStream();
int c;
while ((c = in.read()) != -1)
{
process((char)c);
}
in.close();
}catch (IOException e)
{
}

What is the problem and how may it be fixed??
Any help greatly appreciated
Thanks,
Patrick.

Hi Patrick
The answer is fairly simple (or not...)
The reason why the process is failing is because of your command, it's a built in command, part of "command.com" or "cmd.exe". If you were to choose some other way of doing a dir (e.g. by writing a simple listdir.bat and invoking that instead), then you would have no problem
best regards
Lewin
