Change window location of process started with c#

Question

I'm making a c# console .net framework application to open the file Error.vbs, and I want to be able to choose the location of the started file's window on the desktop.

This is the code I have so far:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Diagnostics;

namespace ErrorRunner
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Process ExternalProcess = new Process();
            ExternalProcess.StartInfo.FileName = @"C:\Users\video\Downloads\Error.vbs";
            while (true)
            {
                ExternalProcess.Start();
            }
        }
    }
}

How would I choose the start location of error.vbs?

(And yes, I know it might be a bad idea to start a process indefinitely, but that's the whole purpose of this program.)

@Chetan that is not what was asked, so I'm not sure why that is relevant — Visne, Jan 02 '22 at 05:26
As per my understanding OP is looking to select the location of vbs file at runtime. — Chetan, Jan 02 '22 at 05:35
@Visne, it gave me hope, but sadly that's not for an external process, so it doesn't work for me — Nomadical, Jan 02 '22 at 05:37

You can retrieve the external process window handle by using ExternalProcess.MainWindowHandle. Maybe you need to wait for process to start completely (see https://learn.microsoft.com/en-us/dotnet/api/system.diagnostics.process.mainwindowhandle?view=net-6.0#System_Diagnostics_Process_MainWindowHandle)

So you can use the handle with a P/Invoke to SetWindowPos (see https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-setwindowpos)
