Move,Load,VisibleChanged 以及 Activated 事件在form显示之前就触发了。

事件的含义：

Move: This event occurs when the form is moved. Although by default, when a form is instantiated and launched, the user does not move it, yet this event is triggered before the Load event occurs.
Load: This event occurs before a form is displayed for the first time.
VisibleChanged: This event occurs when the Visible property value changes.
Activated: This event occurs when the form is activated in code or by the user.
Shown: This event occurs whenever the form is first displayed. 
Paint: This event occurs when the control is redrawn.
Deactivate: This event occurs when the form loses focus and is not the active form.
Closing: This event occurs when the form is closing.
Closed: This event occurs when the form is being closed.

Explain the key events in the lifecycle of the form.

a. Load: fired when form is first loaded in the application

b. Activated: fired whenever the form gets the focus i.e. when loaded first time, restored from the minimize state, whenever the form is brought in front.

c. Deactivated: fired whenever the form looses focus i.e. when form is closed, minimized, when it is in background.

d. Closing: Triggered when application wishes to be closed.

e. Closed: Triggered when application is closed.

f. Disposed: Used for garbage collection.
