Question

i know i could search proccessId / name of running tasks and kill processes i need .

though till now i was not developing schedualed tasks / self executble Applications,

so i didn’t need to know how to make the application close itself after execition

trying to close everything (including WebDriver) via Application.Exit + OR this.Close()
right after i have got what i was looking for. mission Complete .
please close … no more work for you .
but mr . Program.cs still needs somthing from Form1.
saying somthing about
Cannot access a disposed object.
Object name: ‘Form1’.

any combination of both was returning in some point an exeption error
(from program.cs ) even though mission complete . no more code was requested .(?) by me..atleast.

        string extractededVal = Iengn.ExtractPageValue(Iengn.itrfWebEng);
        string flnm = @" the directory path to file --> \dolarRate.asp";



        File.WriteAllText(fn, extractededVal);

        this.Close();
        Application.Exit();
    }

Answer 1

Why use a winform application? A Console application would probably suffice for what you are doing. Once Main() ends your app will close as well. Main() never ends in a winform app because of the applications runloop.

Edit:

Here would be the correct way to do this. You need to register to the forms Load event and run your code there, not in the constructor. You can’t close a winform from inside a constructor.

Edit 2: Put this code in the Form1() constructor. Somewhere after InitializeComponent();

    this.Load += (sender,args)=>{ /*do all your work here*/  
     string extractededVal = Iengn.ExtractPageValue(Iengn.itrfWebEng);
     string flnm = @" the directory path to file --> \dolarRate.asp";
     File.WriteAllText(fn, extractededVal);
     Application.Exit(); 
  };
