Check if Form has focus or is active

I have a Form that shows a Notification Window. But I want to show the popup only when the Form doesn't have focus or is not active, something like this:

if (!form.Active)
{
   //Do something
}

Is there a way to do it?

This may help you on your quest. If your form is active, it'll tell you. If you click off the form, it'll tell you too.

using System; 
using System.Text;          // probably not required
using System.Windows.Forms; // probably not required
using System.Threading;     // probably not required   


namespace AppName
{   

    public partial class Form1 : Form
    {
        
        protected override void OnActivated(EventArgs e)
        {
            Console.WriteLine("Form activated");
        }


        protected override void OnDeactivate(EventArgs e)
        {
            Console.WriteLine("Form deactivated");
        }

       // more program etc.

    }
 }

if (Form.ActiveForm != yourform)
{
   //form not active 
   //do something
}
else
{
   // form active
   // do something
}
