C# OutOfProcess Python

• WaitForExit Method (Int32):
  • true if the associated process has exited; otherwise, false.
  • https://msdn.microsoft.com/en-us/library/ty0d8k56(v=vs.110).aspx
• UseShellExecute:
  • true if the shell should be used when starting the process; false if the process should be created directly from the executable file. The default is true.
  • https://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.useshellexecute(v=vs.110).aspx
• ProcessStartInfo.RedirectStandardOutput:
  • true if output should be written to Process.StandardOutput; otherwise, false. The default is false.
  • https://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.redirectstandardoutput(v=vs.110).aspx
• ProcessStartInfo.RedirectStandardError:
  • true if error output should be written to Process.StandardError; otherwise, false. The default is false.
  • https://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.redirectstandarderror(v=vs.110).aspx
• CreateNoWindow:
  • true if the process should be started without creating a new window to contain it; otherwise, false. The default is false.
  • https://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.createnowindow(v=vs.110).aspx
  • CreateNoWindow works in conjunction with UseShellExecute as follows:

    To run the process without any window:

    ProcessStartInfo info = new ProcessStartInfo(fileName, arg); 
    info.CreateNoWindow = true; 
    info.UseShellExecute = false;
    Process processChild = Process.Start(info); 

    To run the child process in it’s own window (new console)

    ProcessStartInfo info = new ProcessStartInfo(fileName, arg); 
    info.UseShellExecute = true; // which is the default value.
    Process processChild = Process.Start(info); // separate window

    To run the child process in the parent’s console window –-> This is what we are using

    ProcessStartInfo info = new ProcessStartInfo(fileName, arg); 
    info.UseShellExecute = false; // causes consoles to share window 
    Process processChild = Process.Start(info); 

• WindowStyle :
  • is a recommendation passed to the process
  • One of the enumeration values that indicates whether the process is started in a window that is maximized, minimized, normal (neither maximized nor minimized), or not visible. The default is Normal.
