Use Windows Mobile to obtain and block incoming calls

I received a special task today. I got a call number from Windows Mobile. In fact, it has a call display, but now I want to write it myself.ProgramTo display the incoming call...

No way... although I have never done it... it seems that this stuff is important... so I am still confused. I am going to find information online... Yes !~~~

 

The method is as follows:

Automatic incoming call
The local method of keybd_event is used to stop the call.

Public   Static   Class Dropcall
{
# Region Private Field
// VK key F4 of the end key
Private   Const   Int Vk_f4 =   0x73 ;
Private   Const   Int Keyeventf_keyup =   Zero X 0002 ;
# Endregion

# Region Public Field
// Banned phone number list
Public   Static List < String > Bannedlist =   New List < String > ();

/**/ ///   <Summary>
/// Simulate a key operation
///   </Summary>
Public   Static   Void Drop ()
{
Myref. keybd_event (vk_f4, 0 , 0 , 0 );
Myref. keybd_event (vk_f4, 0 , Keyeventf_keyup, 0 );
}
# Endregion
}

The systemstate class and systemproperty class are used to obtain the incoming call number.

# Region Attach event Delegate
Systemstate state =   New Systemstate (systemproperty. phoneincomingcallernumber );
Systemstate SS =   New Systemstate (systemproperty. phoneincomingcall );
SS. Changed + =   New Changeeventhandler (ss_changed );
State. Changed + =   New Changeeventhandler (state_changed );
# Endregion

We use the cellular simulator to simulate incoming calls.

The program running effect is as follows:

 

In addition, you can set up a series of phone numbers that you don't want to answer, so that the program will hang them up for you.
For example:

# Region Initialize the blocked number list
Dropcall. bannedlist. Add ( " 1 (312) 132-132 " );
# Endregion

When you dial the number 13112132132 in cellular emulator, the simulator will help you stop it.
