How to pop up a message box when user clicks anywhere within the form window in Visual Studio?

Question

I'm fairly new to Visual Studio in C#.

I was wondering how to pop up a message box when the user clicks anywhere within the form window.

Basically, I don't want them accessing and interacting with the program unless they have a password.

Code for the Form1() is really simple right now:

public Form1()
{
    InitializeComponent();
}

The actual interface has a bunch of buttons and settings (buttons and settings I don't want the user to be able to interact with unless they have verified themselves).

Answer 1

Click on form and press F4 key that show property window then click on event button there you click on click event that show in .cs file of form .

Make function like

private void Form1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("Click");
        }

Answer 2

regarding the 1st questions. You usually create a second model form , that is transparent and is on top of your form. Handle the on-click event of the transparent form .

Regarding the second questions- you should rethink your design , maybe do not show the sensitive form at all untill a user has typed the password.

By the way , you have not specified what tech do you use? is it desktop (winforms / wpf , other)/ web (web forms, asp mvc, other) ?

Edit: In order to put a form on top of another form , you use a model dialog.

Also , it still depends on your UI technology.

Provided links are form winforms, other technology may require a different approach.

Edit: As another answer pointed out , you could also bind to the original forms click event , but you will also have to bind to every child control click event recursively.
