Solution 1

This error is telling you that the Python executable is not present in the %PATH% command. What you could do here is add the following code:

C#

start.FileName = @"c:\PathToPython\Python";
start.Arguments = @"C:\Users\rahuls1\Desktop\DEmo\Temp\demo.py";

now error is that system could not find the specified File after adding the Code..

Pete O'Hanlon 27-Jan-14 5:23am

Have you added the right path to the python executable?

rahuls1 27-Jan-14 5:32am

python executabel will be in starT.FILENAME..

rahuls1 27-Jan-14 5:32am

ProcessStartInfo start = new ProcessStartInfo();
// start.FileName = @"C:\Users\rahuls1\Desktop\DEmo\Temp\demo.py";
start.FileName= @"c:\Users\rahuls1\Desktop\DEmo\Temp\demo.exe";
start.Arguments = @"C:\Users\rahuls1\Desktop\DEmo\Temp\demo.py";
start.ErrorDialog = false;
start.UseShellExecute = false;
start.RedirectStandardError = true;
start.RedirectStandardInput = true;
start.RedirectStandardOutput = true;
start.CreateNoWindow = true;

using (Process process = Process.Start(start))
{
using (StreamReader reader = process.StandardOutput)
{
string result = reader.ReadToEnd();

}
}
THIS IS THE CODE I AM USING..

start.FileName isn't pointing to PYTHON though. I thought I was clear in telling you that it had to point to the python executable.

rahuls1 27-Jan-14 5:38am

please make it clear ..

Pete O'Hanlon 27-Jan-14 5:42am

I have made it clear. It couldn't be ANY clearer. You are trying to run a python code. This will only work if PYTHON.EXE invokes it - which is the reason why you have to provide a path to the PYTHON executable to run it.

i am doing that in star.FileName

NTVDM CPU has encounter an illegal instruction.

Pete O'Hanlon 27-Jan-14 5:58am

You state that your code is: start.FileName= @"c:\Users\rahuls1\Desktop\DEmo\Temp\demo.exe"; That does not point to the Python executable. That points to an application called demo.exe.

Solution 2

That is the code for launching a Python script. It doesn't work if Python is not installed on your system.
