Hi,
Can any one help me out in executing this code?

C#

string command = @" tf help > tfshistory.txt";
System.Diagnostics.ProcessStartInfo procStartInfo =
new System.Diagnostics.ProcessStartInfo(@"cmd", @" C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat" + command);

// The following commands are needed to redirect the standard output.
// This means that it will be redirected to the Process.StandardOutput StreamReader.
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
// Do not create the black window.
procStartInfo.CreateNoWindow = true;
// Now we create a process, assign its ProcessStartInfo and start it
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = procStartInfo;
proc.Start();
// Get the output into a string
string result = proc.StandardOutput.ReadToEnd();
// Display the command output.
Console.WriteLine(result);
MessageBox.Show(result);

Thanks,
Prakash

If you break the problem into steps you have

1) Start the command processor
2) run vcvarsall.bat
3) run "tf help > tfshistory.txt"

So you actually want to run two commands not one and that will require the use of the "&" operator.

C#

private static void RunCmds() {
  const String batch1 = @"SetVars.cmd";
  const String batch2 = @"ReadVars.cmd";
  const String argsFormat = "/c {0} & {1} > output.txt";

  ProcessStartInfo psi = new ProcessStartInfo();
  psi.FileName = Environment.GetEnvironmentVariable("COMSPEC");
  psi.Arguments = String.Format(argsFormat, batch1, batch2);
  psi.UseShellExecute = false;
  psi.CreateNoWindow = true;
  Console.WriteLine("File: {0}", psi.FileName);
  Console.WriteLine("Args: {0}", psi.Arguments);
  Process p = Process.Start(psi);
  p.WaitForExit();
  Console.WriteLine(File.ReadAllText("output.txt"));
}

My batch files used for testing are

REM SetVars.cmd
SET ANIMAL=Chinchilla
SET CHARACTERISTIC=fluffy

@echo off
REM ReadVars.cmd
echo %ANIMAL%s are %CHARACTERISTIC%

and the console output is

File: C:\WINDOWS\system32\cmd.exe
Args: /c SetVars.cmd & ReadVars.cmd > output.txt
Chinchillas are fluffy

Ooh nice!

Why don't you create your own .bat file with the commands required? This call seems too overloaded with parameters. You launch command processor which should execute .bat file (actually used to set environment variables and calling other .bat files internally) which shall receive your command arguments which are supposed to be another command call with parameter and output redirection... seriously, what do you expect?
