I am using vb.net form. I was wondering if there is an event (or way ) that check if when the user click the close form button?

If yes, can you also cancel the form from closing ?

Yes, there is a way, oddly enough, its called the FormClosing event, and you just need to intercept it.

FormClosing Event[^] on MSDN has a good reference for how to use it.

Yes, and yes.
Handle the Form.FormClosing event, and it will give you a FormClosingEventArgs as a parameter.
This contains a property CloseReason[^] which gives you as much info as you are going to get, and also has a Cancel[^] property that you can set to True if you want to prevent it closing.
Note: if you always cancel the Form Close, you will seriously annoy your users! Provide some mechanism for them to get out...
