So im trying to create a program pretty much that will open other programs upon exit or with a time delay. I get no build errors but everytime i RUN my program i get the ERROR Cannot start process because a file name has not been provided. but launches the first program anyways just not the other one upon exit. anyone see any issues with the code i provided. Thanks alot appreciate any help

Code: [Select]using System;
using System.Diagnostics;
using System.Diagnostics.Contracts;

namespace ProcessExitSample
{
class testsandboxprogram
{
static void Main(string[] args)
{
Contract.Requires(args != null);
try
{
//why in the literal *censored* am i getting an error for no name!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!WHEN I DEFINED THE PATH
var firstProc = new Process();
Process.Start(@"PATH TO EXE I WANT TO LAUNCH");
firstProc.EnableRaisingEvents = true;

firstProc.Start();

firstProc.WaitForExit();

//so upon exit should run the second program here
Console.WriteLine("First process exited: " + firstProc.ExitCode);

var secondProc = new Process();
Process.Start(@"PATH TO PROGRAM I WANT TO LAUNCH");
secondProc.Start();

}
catch (Exception ex)
{
Console.WriteLine("Something went wrong sorry :(: " + ex.Message);
return;
}
}
}
}Process.Start() isn't going to give the firstProc instance any information about the file you specified as a parameter, as it creates a new Process and starts it and returns that Process as the return value.

You probably want something like this:

Code: [Select] ProcessStartInfo FirstProcInfo = new ProcessStartInfo(@"C:\Path\To\executable.exe");
var FirstProc = Process.Start(FirstProcInfo);
FirstProc.WaitForExit();
ProcessStartInfo SecondProcInfo = new ProcessStartInfo(@"C:\Path\To\second\executable.exe");
var SecondProc = Process.Start(SecondProcInfo);

var FirstProc = Process.Start(FirstProcInfo);
FirstProc.WaitForExit();
ProcessStartInfo SecondProcInfo = new ProcessStartInfo(@"C:\Path\To\second\executable.exe");
var SecondProc = Process.Start(SecondProcInfo);

That code wouldn't even compile. You defined the v ariable as FirstProc but then used it as firstProc.

anyway, Steam changes everything. When you launch a steam-managed game by itself it will launch steam telling it to launch itself and exit, so WaitForExit() will return immediately.

I don't get "method or Operation is Not Implemented".
