1. Form and interface design-form Animation

You can add some animation effects on the form to add some fun for the operator.

Scroll subtitles in the 031 form

The effect of rolling subtitles is actually to change the text position. The best way to display a string of text on the form is to use the Label control. You can change the position of the Label control to the position of the text. If the position of the Label control is constantly moving horizontally, the text will scroll. You can change the horizontal position of the Label control by changing the value of the Left attribute of the Label control. Use the Timer control to control the time of text movement.

Create a project. The default form is Form1. Add the Label control on the form to display the message. Add the Button control to control the movement of the message and the Timer control to control the scroll speed.

Namespace _ 031_MoveWindows {public partial class Form1: Form {public Form1 () {InitializeComponent ();} private void button#click (object sender, EventArgs e) {timer1.Enabled = true; // start rolling} private void button2_Click (object sender, EventArgs e) {timer1.Enabled = false; // stop rolling} private void button3_Click (object sender, EventArgs e) {this. close ();} private void timereffectick (object sender, EventArgs e) {label1.Left-= 2; // set the distance between the left edge of label1 and the left edge of the container's workspace. if (label1.Right <0) {label1.Left = this. width; // set the distance between the left edge of labal1 and the left edge of the container's workspace to the Width of the form }}}}

032 animation display form

Windows provides an API function, AnimateWindow, which can be used to animation the form.

: The namespace System. RunTime. InteropServices must be referenced when calling Windows API functions.

Create a project. The default form is Form1. Add the PictureBox control to the form and set the Image attribute of the PictureBox control.

Namespace _ 032_FalshWindows {public partial class Form1: Form {public const Int32 AW_HOR_POSITIVE = 0x00000001; public const Int32 AW_HOR_NEGATIVE = 0x00000002; public const Int32 AW_VER_POSITIVE = 0x00000004; public const Int32 AW_VER_NEGATIVE = 0x00000008; public const Int32 AW_CENTER = 0x00000010; public const Int32 AW_HIDE = 0x00010000; public const Int32 AW_ACTIVATE = 0x00020000; public const Int32 AW_SLIDE = 0x00040000; public const Int32 AW_BLEND = 0x00080000; public Form1 () {InitializeComponent (); // initialize the animation window (this. handle, 300, AW_SLIDE + AW_VER_NEGATIVE); // start form animation} [DllImportAttribute ("user32.dll")] private static extern bool AnimateWindow (IntPtr hwnd, int dwTime, int dwFlags ); private void form=formclosed (object sender, FormClosedEventArgs e) {AnimateWindow (this. handle, 300, AW_SLIDE + AW_VER_NEGATIVE + AW_HIDE); // end form animation }}}

033 create a flickering form

Windows provides an API function FlashWindow, which can flash the form. This function can only make the form flash. If the window is non-stop flashing, you need to use a Timer control to call this function to make the form flash every other time.

Create a project. The default form is Form1. Add the PictureBox control to display the form, set the Image attribute of the PictureBox control, and add the Button control and Timer control to start and stop flashing.

Namespace _ 033_ShanShuoWindows {public partial class Form1: Form {public Form1 () {InitializeComponent ();} private void button#click (object sender, EventArgs e) {timer1.Enabled = true; // start timer1 timer} private void button2_Click (object sender, EventArgs e) {timer1.Enabled = false; // disable timer1 timer} [System. runtime. interopServices. dllImportAttribute ("user32.dll")] public static extern bool FlashWindow (IntPtr handle, bool bInvert); private void timer1_Tick (object sender, EventArgs e) {FlashWindow (this. handle, true); // start the form blinking function }}}

034 implement the taskbar Notification Window

The time events of the Timer component are used to determine the status of the form. In the display process, the ShowWindow function provided by Windows is used.

1. Create a project. The default form is TaskMessageWindow. Add a Window form and name it MainForm.

2. Add two Button controls, three Label controls, one TextBox Control and one RichTextBox Control to the TaskMessageWindow form, and set the StartPosition attribute of the form to CenterScreen.

3. add two Label controls, three Timer controls, one PictureBox control, one ImageList control, and one policyicon control to the MainForm. Modify the Interval attribute of the Timer1 component to 1000, the Interval attribute of the Timer2 component is 400.

Reference: Winform switch or reset the tray icon

035 animated Program Interface

Microsoft Animation Control 6.0 (SP4) is mainly used. Therefore, you need to add this component to the toolbox from the toolbox "select item" and then add the component from the toolbox to the form.

: Because the AxAnimation class is used, you must add a reference to the WMPLib namespace.

Create a project. The default form is Form1. Add the Panel Control on the form to display the image, and add the Microsoft Animation Control 6.0 (SP4) component to play the Animation.

using WMPLib;namespace _035_LeadWindows{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private void Form1_Load(object sender, EventArgs e)        {            axAnimation1.Open("Electron.avi");            axAnimation2.Open("zybiao.avi");            axAnimation3.Open("gd.avi");        }    }}
