Question

E.g. instead of having a button to initiate the method, the method automatically happens without any user interaction – automatically.

private void button13_Click(object sender, EventArgs e)
{
    try
    {
        ServiceController sc = new ServiceController();
        sc.ServiceName = "Spooler";

        if (sc.Status.ToString().ToLower() == "stopped")
        {
            serviceStatusLabel.Text = "Installed but stopped";
        }

        if (sc.Status.ToString().ToLower() == "running")
        {
            serviceStatusLabel.Text = "Installed and started";
        }
    }
    catch
    {
        serviceStatusLabel.Text = "Service not installed";
    }
}

I just want the Label object to show the service status when the form is loaded up, without using a button

Answer 1

… Do I get your question correctly?
You want a piece of code to be executed when an object or the form is loaded?
Well that’s easy :p

Click on your object (or form) in the designer, in the properties dock, click the lightning bolt icon, go to the Load or Show event, and double-click the box.
A new piece of code should now be created in the code view, something like this:

private void Object_Load(blabla) handles Object.Load
{
}

Whatever code is in that event will be executed when the object is loaded or shown.
