Hello,  
Does anyone know whether it is possible to temporally disable the colose button (in the upper right corner) of my app window as it is in Back up window while backing up?

## you can try another option: whenever a user click “close” button, check if you are backuping or doing other jobs using FormClosing event. The following is an example posted on the web for your reference. It is written in C#

private void Form1\_Closing(object sender, System.ComponentModel.CancelEventArgs e)  
{  
// check if you are backing up something  
if(MessageBox.Show(“Are you sure you want to exit?”, “Confirm exit”, MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.No)  
{// ignore close behave  
e.Cancel = true;  
}  
}
