accessing windows application from console

anandthecoolest · February 18th, 2007, 01:04 PM

i want to access bat file from the windows application..
i shall be passing multiple arguments from the environment...
basically i shall be running a code review tool and then i want to store the output from the console in an intermediate file for further processing...
can u suggest me ways to do it ?
i tried using the system "process" class and then creating a process and running it from environment... i had given the command ">a.txt" in the arguments list to create the text file of the output.. but a blank file of the name a.txt was created. and on console the same command runs without error and proper text file is created. can u help me out ? or suggest other methods to save the output from console to process it ( mayb as a string or sumthin )
thanks ppl

Hi Anand,

There is a way to redirect the output of a console window you start from an application, by using the ProcessStartInfo class with your Process object. You can find the full details on MSDN:
http://msdn2.microsoft.com/en-us/lib...ardoutput.aspx

A simple example:

Code:

// create the process
Process myproc = new Process();
// set file and arguments
myproc.StartInfo.FileName = "myconsole.exe";
myproc.StartInfo.Arguments = "someargument";
// this must be false to let us get output
myproc.StartInfo.UseShellExecute = false;
// tell it to redirect
myproc.StartInfo.RedirectStandardOutput = true;

// start process up
myproc.Start();    
// get the output
string output = myprocess.StandardOutput.ReadToEnd();
// let process finish
myproc.WaitForExit();

/* output is now a string, so you can save to a file */

If you're not careful, you can get confusing problems with the 2 programs deadlocking each other, e.g. both waiting for input, but the MSDN page is fairly good at explaining it.

Hope this helps
Phil
