Closing event triggered for both UserClosing and this.close

Question

I have a form that has a LogOutEvent event and a form close event. Here is the code

private void btnLogOut_Click(object sender, EventArgs e)
{
       DialogResult yesNo = MessageBox.Show(this, "Are you sure you want to Log Off?", "Log Off", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button1);

        if (yesNo == DialogResult.Yes)
        {
            new LoginForm();
            this.Close();
            string tst2 = Logout(AgentId, AgentPwd, ExtensionId);
            if (tst2 == "TCF000")
                MessageBox.Show(" Logout Success");
            else
                MessageBox.Show("Logout Failed");
        }
}

And closing the form

private void MainGUI_FormClosing(Object sender, FormClosingEventArgs e)
{
        if (e.CloseReason == CloseReason.UserClosing)
        {
            DialogResult yesNo = MessageBox.Show(this, "Are you sure you want to Log Off?", "Log Off", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button1);

            if (yesNo == DialogResult.Yes)
            { 
                Application.Exit();
            }
            else
            {
                e.Cancel = true;
            }
         }
}

My problem is when I click the LogOut button, triggering a form close event. Can anyone advise a better code for this?

When I click on "X", he should close the application, and when I click on LogOut, he should close the current window and go to the login form.

Answer 1

I am sure there is a better solution, but this works:

private bool loggingOut;

private void Form1_DoubleClick(object sender, EventArgs e)
{
    this.loggingOut = true;
    this.Close();
    // This is optional as we are closing the form anyway
    this.loggingOut = false;
}

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    if (e.CloseReason == CloseReason.UserClosing && !loggingOut)
    {
        // Handle form closing here
    }
}
