Process in/out-Put to Streams in DOS-Box-like utility

Hi!

I´m currently programming a GUI for a Command-Line-Based System. The administration is done with a command-line-Admin-Tool similar to Windows´ CMD-Dos-Box.

Unfortunately i cannot run the admin-commands on their own, because the only run in this cmd-line-based gui, which seems to be an stand-alone interpreter, not a dos-box running seperate programs...

Also there is no API available i could use.

What i´d like to do is to call a DOS-Box/Admin-Tool via the Process-Object and send my commands to it via the StandardInput-Object.

Sending works fine, but when I do the reading from StandardOutput-Stream, i cannot find an end-mark for my while-Statement.
(For testing-purposes i send everything to the system-console in order to see, what comes back from my process)

string sto = null;
string ste = null;
while ( ((sto = process.StandardOutput.ReadLine()) != null) || ((ste = process.StandardError.ReadLine()) != null) )
{
if (sto != null)
System.Console.WriteLine(sto);
if (ste != null)
System.Console.WriteLine(ste);
sto = null;
ste = null;
}

When the command has finished, the loop hangs in the ReadLine-Statements.

Peeking into the stream doesn´t work and hangs also...

How could i do this?

Thanks a lot!

J.

is this what you're looking for ?

StreamReader output = Process.StandardError;
string stdout = output.ReadToEnd();

maybe you don't need the while loop ?

you need to read the output (and error) stream in a seperate thread.
