Unable to Read the total Output from the Command Prompt

[sdanda]

Hi,
I am working on C# windows applications.What i want to do is, I want to Redirect the output from Command Prompt to the Rich Text Box, Actually i am unable to read the entire output of the comman prompt, but i can see only the few lines.I don't know what's the wrong in my code.Here is the sample code.
ChildLaunch()
{
Process p = new Process();
p.StartInfo.WorkingDirectory = RootDir;
p.StartInfo.FileName = Environment.GetEnvironmentVariable("COMSPEC");
p.StartInfo.Arguments = "/c" + " " + CommandLine.Trim();
p.OutputDataReceived += new DataReceivedEventHandler(p_OutputDataReceived);
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
p.StartInfo.UseShellExecute = false;
p.EnableRaisingEvents = true;
p.Start();
p.BeginOutputReadLine();
}
void p_OutputDataReceived(object sender, DataReceivedEventArgs e)
{
richTextBox1.AppendText(e.Data);
}


Here RootDir is the working directory which we have to set in the command prompt. CommandLine is the String which i used in my code to collect all the elements from the GUI.
Using my code I can read only some amount of output.. But i need to read the entire output. Can any one help me?

After p.Start(), do

String output = p.StandardOutput.ReadToEnd();

You can then send that output wherever you want.

Hi,
I already tried by placing that statement but even after giving that statement i am unable to read the complete output

The sample code with the above statement is
delegate declaration:-
delegate void WriteToRichTextBox(string Msg);

Thread declaration:-
Thread t=new Thread(new ThreadStart(ChildLaunch);
t.Start();


void ChildLauch()
{
Process p = new Process();
p.StartInfo.WorkingDirectory = RootDir;
p.StartInfo.FileName = Environment.GetEnvironmentVariable("COMSPEC");
p.StartInfo.Arguments = "/c" + " " + CommandLine.Trim();
p.OutputDataReceived += new DataReceivedEventHandler(p_OutputDataReceived);
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
p.StartInfo.UseShellExecute = false;
p.EnableRaisingEvents = true;
p.Start();
richTextBox1.Invoke(new WriteToRichTextBox(WriteText),new object[] {p.StandardOutput.ReadToEnd().ToString()});
p.Close();
}

public void WriteText(string msg)
{
richTextBox1.AppendText(msg);
}

Here even if i use synchronous ReadToEnd() function i am unable to see the total Command Line Output

What if you use
p.WaitForExit(WithAMillsecondsTimeOut); ?

Have you checked to see if there is output on the Standard Error stream?
