from createwindow//ncmdshow:the fourth parameter F Rom Winmainshowwindow (hWnd, ncmdshow); UpdateWindow (HWND);So far, this window is not displayed because we have not implemented the WndProc function yet.
The last step of WinMain is the message loop. The purpose of this loop is to listen for messages sent by the operating system. After the application receives the message, it dispatches the message to the WndProc function for processing. The message loop resembles the following:View Copy

Moderator gave the answer, but also can parse out, but found out the results and the actual results are completely different, such as the server returned to me is: ip:107.145.107.140, port:26773
But I resolved it into: ip:46.48.46.48, port:63271
This is far away, I use PHP to get nodes information, and then the nodes information to parse the output, by the way, the unresolved data sent to Pthon parsing aga
registration: Register with the label life in Androidmanifest.xml and set the filter in the label.
Dynamic registration: use Intentfilter to dynamically register a broadcast in code
Intentfilter intentfilter = new Intentfilter ();

Registerreceiver ( Broadcastreceiver,intentfilter);
Also noteworthy is that when we use dynamic registration, when th

queueA queue can be implemented by a linked list or by an array, where the loop linked list implemented by the array is used as the queue model for our message queue.typedef struct QUEUE_S {int head; int rear; sem_t sem; msg_t Data[queue_size]; }queue_t; int Msgqueueinit (queue_t* Q) {if (!

Possible problems with compiling code when the GCC version is high in Linux
The problem is this, first look at the function prototype:
void SomeFunc (char *somestr);
And look at this function call:
SomeFunc ("I ' m a string!");
Combine these two things and compile them with the latest g++ to get a warning in the title.
Why, then? the original char * behind the meaning is: Give me a string, I want to modify it.
In theory, the literal constants we pass to a function cannot be modified .
