How can i know when an Application.exe is running and when is closed in VB.Net?

I wish this help you I am currently developing an application that opens a program.exe with a login, but I need to know when that application closes. Maybe I will monitor the process of that program, but I don't know how to do it. , You can check Process.HasExited
code :
Private Async Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

    Dim p = Process.Start("notepad.exe")

    While Not p.HasExited
        Await Task.Delay(100)
    End While

    MessageBox.Show("Closed")
End Sub

Keep VB.NET application running in the background after base form closed

this will help In the options of your project, set the “Startup Object” to “Sub Main” instead of of a form name. You might have to disable the setting “Application Framework” first.
Now you have to launch the form manually because it’s no longer done automatically, but on the other hand you can now control when to launch it, and your application will exit when it reaches the end of the Main method (or when it’s quit explicitly) rather than when the form closes.

Keep broadcast receiver running after application is closed

like below fixes the issue I need to keep broadcast receiver running all the time after app has been started. , You can use a service
In main app start/stop the service
code :
Intent service = new Intent(context, MyService.class);
context.startService(service);
...
Intent service = new Intent(context, MyService.class);
context.stopService(service);
public class MyService extends Service
{
 private static BroadcastReceiver m_ScreenOffReceiver;

 @Override
 public IBinder onBind(Intent arg0)
 {
  return null;
 }

 @Override
 public void onCreate()
 {
  registerScreenOffReceiver();
 }

 @Override
 public void onDestroy()
 {
  unregisterReceiver(m_ScreenOffReceiver);
  m_ScreenOffReceiver = null;
 }

 private void registerScreenOffReceiver()
 {
  m_ScreenOffReceiver = new BroadcastReceiver()
  {
   @Override
   public void onReceive(Context context, Intent intent)
   {
     Log.d(TAG, "ACTION_SCREEN_OFF");
     // do something, e.g. send Intent to main app
   }
  };
  IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_OFF);
  registerReceiver(m_ScreenOffReceiver, filter);
 }
}

If an application is not closed (running in background) , does it cause application crash?

wish of those help I suggest reading the Activity documentation. The Android OS has its own application lifecycle management. Each activity is kept "alive" until its onDestroy is called. For example, the OS can keep an activity alive for several hours and then kill it when there is not enough memory to perform other tasks.
What happens in you case is most likely that the same activity re-runs when you open you app again (in the emulator the activity is probably killed before) and you're in a bad state since probably some of the objects were disposed or re-initialized.
code :
public class SomeActivity extends Activity
{
     public void onCreate()
     {
         super.onCreate();
         // Do some object initialization
         // You might assume that this code is called each time the activity runs.
         // THIS CODE WILL RUN ONLY ONCE UNTIL onDestroy is called.
         // The thing is that you don't know when onDestry is called even if you close the.
         // Use this method to initialize layouts, static objects, singletons, etc'.    
     }

     public void onDestroy()
     {
         super.onDestroy();
         // This code will be called when the activity is killed.
         // When will it be killed? you don't really know in most cases so the best thing to do 
         // is to assume you don't know when it be killed.
     }
}
public class SomeActivity extends Activity
{
     public void onCreate()
     {
         super.onCreate();
         // Initialize layouts
         // Initialize static stuff which you want to do only one time  
     }

     public void onDestroy()
     {
         // Release stuff you initialized in the onCreate
     }

     public void onResume()
     {
         // This method is called each time your activity is about to be shown to the user,        
         // either since you moved back from another another activity or since your app was re-
         // opened.
     }

     public void onPause()
     {
         // This method is called each time your activity is about to loss focus.
         // either since you moved to another activity or since the entire app goes to the 
         // background.
     }

How to keep the application running when the last window is closed?

should help you out I'm working on a very basic GUI project in Qt (using c++) and want to be able to close the main window in my program without the program quitting all the way. By default, it will exit when the main window is closed. How to prevent that? , Set the QApplication::quitOnLastWindowClosed property to false:
