Process and Cmd.exe problem

[Robert]

Hello,

I am doing an automatic backup service using c# and VS2003.
To achieve this i must call an executable file. So far I have made
it all work using Process, code looks like this:

Process cmd = new Process();
StreamWriter sw;
StreamReader sr;
StreamReader err;
 
cmd.StartInfo.RedirectStandardInput = true;
cmd.StartInfo.RedirectStandardOutput = true;
cmd.StartInfo.RedirectStandardError = true;
cmd.StartInfo.CreateNoWindow = true;
cmd.StartInfo.UseShellExecute = false;
cmd.StartInfo.FileName = "cmd.exe";
 
cmd.Start();
 
sw = cmd.StandardInput;
sr = cmd.StandardOutput;
err = cmd.StandardError;
 
sw.AutoFlush = true;
if (textBox1.Text != "")  // textBox1 contains the path+name of .exe
sw.WriteLine(textBox1.Text);
 
sw.Close();
 
richTextBox1.Text = sr.ReadToEnd();
richTextBox1.Text += err.ReadToEnd();
 

Problem is that the executable may in most cases
ask for a password. I have found no way how to check
for this and supply the password. After executing the
above code the Process terminates.

How can I tell the Process to wait if the executable is
waiting for input? Or is there another way to accomplish
this??

Kind Regards,
Robert

I still haven't found a solution to my problem, but I am trying another
approach now.

If i set StartInfo.UseShellExecute = true, and StartInfo.FileName = "cmd.exe".
A cmd window will open. How can I from c# send commands to this windows?

If this is possible then my problem should be solved.
Kind Regards,
Robert
