Question

Hi I am trying to do the following:
I have a process which can take parameters (digits)
and return the sum of these numbers

Process P = Process.Start(sPhysicalFilePath, Param);
                int result = P.ExitCode;

I get the return value from “ExitCode”
the problem is:
the program sometimes finishes his work before the process
so when the program reaches this line

int result = P.ExitCode;

I got an exception ..
my question is how to wait this process until it finishes its work
sorry I forget to say that’s I am working with C# language

Answer 1

use:

Process P = Process.Start(sPhysicalFilePath, Param);
P.WaitForExit();
int result = P.ExitCode;
