Assuming this is a WinForms application: what is the Main Form ? Is it the case that you need to close the Main Form while keeping the application "alive" ? Yes ... this is possible, though not done very often.

1.declare any global variable or flag where you can set that is there any changes happened or not. Its simple.
2. You have to check that variable's value on close button click. Here is the code to get that.

C#

private void Form1_FormClosing(object sender, FormClosingEventArgs e) {
    if (string.Equals((sender as Button).Name, @"CloseButton"))
        // Do something proper to CloseButton.
    else
        // Then assume that X has been clicked and act accordingly.
}
