C # Writing automatic shutdown Program Review knowledge

First, the first element of a program is the logo

In the settings you can set the program icon, in the icon set.

Icon icons can be downloaded online.

These are all superficial kung fu

The program involves Buton, Label, Timer, Notiflcon control

Button control to design a click event

As shown below:

private void Button1_Click (object sender, EventArgs e)        {           //int shi, fen, Miao;            if (flag_true = = 0)            {                flag_true = 1;            }            else            {                button1. Text = "OK";                Label6. Text = "";                Label7. Text = "";                Label5. Text = "";                Label1. Text = "Timer shutdown settings";                flag_true = 0;            }            Shi = (int) numericupdown3.value;            Fen = (int) numericupdown2.value;            Miao = (int) numericupdown1.value;            Time_set = shi * 3600 + fen * + miao;        }

Label control is simple to operate

Ability to display characters, and its members have text, you can change the text at any time

The timer control is equivalent to the timer in the embedded, set enable in the behavior column of the attribute and set interval time interval 500 is half a second.

private void Timer1_Tick (object sender, EventArgs e) {Int32 time_now;            Int32 Extra; if (flag_true = = 1) {if (DateTime.Now.Minute = = Fen && DateTime.Now.Hour = = Shi &&A mp DateTime.Now.Second = = Miao) {button1.                    Text = "Cancel"; Label6.                    Text = "Remaining shutdown time"; Label7.                    Text = "seconds"; Label5.                    Text = "0";                System.Diagnostics.Process.Start ("Shutdown", "-s-t 0");//Shutdown Program}//shutdown Else                    {Time_now = DateTime.Now.Second + DateTime.Now.Minute * + DateTime.Now.Hour * 3600;                    Extra = Time_set-time_now; if (Extra > 0) {button1.                        Text = "Cancel"; Label6.                        Text = "Remaining shutdown time"; Label7.                        Text = "seconds";                     extra/3600   Label5. Text = extra.                    ToString ();                    } else {flag_true = 0; }                                                            }            }        }

I go to interrupt every half second, judge, if you have set a timed shutdown, determine whether to reach the shutdown time, and show how many seconds left off. If you do not set a timed shutdown, it is not displayed.

The text of Button1 and label can be changed at any time.

Basic function Setup Complete

And then there's a setup to minimize to the pallet

Use the Notiflcon control

This control sets the minimize icon, which can be set in the icon.

He has an event with a mouse click, double click on the mouse, and double-clicked.

private void Notifyicon1_mouseclick (object sender, MouseEventArgs e)        {this            . Visible = true;             This. WindowState = Formwindowstate.normal;             This.notifyIcon1.Visible = false;         }

The above I set the mouse click, the code is to restore the visual, Normal window.

Again, the Setup program is minimized and hidden below.

private void Form1_sizechanged (object sender, EventArgs e)        {            if (this. WindowState = = formwindowstate.minimized)             {this                 . Hide ();                 This.notifyIcon1.Visible = true;             }         }

The above is a shutdown program, do their own play.

The overall architecture is as shown.
