Encapsulated classes: Windows7Taskbar, ThumbButtonManager, ThumbButton, JumpListManager, RegistrationHelper, etc.

Windows7Taskbar is used for registration and initialization. ThumbButtonManager manages ThumbButton, including the create button, JumpListManager history, and RegistrationHelper associated file type.

Steps:

1. Reference

Using windows7.20.topintegration;
Using windows7.20.topintegration. WindowsForms;

2. Initialization (when loading the form)

Windows7Taskbar. AllowTaskbarWindowMessagesThroughUIPI ();
Windows7Taskbar. SetCurrentProcessAppId ("TaskbarManaged"); // you can customize the parameters.

3. Create button

ThumbButtonManager buttonManager = this. createThumbButtonManager (); ThumbButton taskbarBtnPause = buttonManager. createThumbButton (101, Properties. resources. playtask, "play"); taskbarBtnPause. clicked + = (sender, e) =>{ btnPlay_PictureClick (sender, e); if (IsPlay = true) // check whether the video is being played. Update the icon {taskbarBtnPause. icon = Properties. resources. playtask;} else {taskbarBtnPause. icon = Properties. resources. pausetask ;}
};
ButtonManager. AddThumbButtons (taskbarBtnPause );

4. capture information

protected override void WndProc(ref Message m)
{　　if (buttonManager != null)   　　buttonManager.DispatchMessage(ref m);　　base.WndProc(ref m);
}

:

Note that:

A maximum of seven buttons can be added or deleted. After initialization, you can only make them unavailable or hidden. You can call the ThumbBarAddButtons and ThumbBarUpdateButtons methods to control the toolbar.

Adding ThumbButton during the Load time of the form does not work, which is why I did not add ThumbButton when loading the form, and each ThumbButton has an ID, which is assigned by you, it cannot be repeated.

Problems:

I added a Processing Event to taskbarBtnPause. Clicked, that is, the change Icon. The result is that the ThumbButton attribute Icon is modified when the event is triggered, but the interface is not updated.

C language ^ how to use

A1 = 0x01; // 0000 0001
A2 = 0x00; // 0000 0000
A3 = 0x03; // 0000 0011
A4 = 0x02; // 0000 0010

B1 = a1 ^ a2; // 0000 0001
B2 = a1 ^ a3; // 0000 0010
B3 = a1 ^ a4; // 0000 0011

^ XOR operator. The bitwise value is 0 and the difference is 1. See the example above.

//
Examples of simple and practical problems:
====================================
======= A ======= B =========
There are two circuits on the top. The two switches are a and B respectively. The opening status is \ [1], and the closing status is/[0].
If both circuits are enabled or disabled.
If a turns on [1], B turns off [0], and circuit 1 Powers on
=====================
If a disables [0], B enables [1], and circuit 2 powers on.
====================================
In summary, the circuit fails in the and B states simultaneously [0]. When a and B are different, the power is charged [1].
