Everybody, everybody!

I just started to learn programming, there is a problem I met in real life

Sometimes when using WeChat PC client, can appear the WeChat icon on the taskbar in the flash, click the icon, however, found no news, so I think a problem, the Windows for a flash events in the history of the software in the task bar will appear in which the event log?

thank you

Before doing a code, WeChat is WIN32 application to

 # pragma warning (disable: 4996);//close "may not be safe code" warning, if not close, program cannot run; 
The ATOM MyRegisterClass (PWNDCLASSEX, HINSTANCE); 
HWND InitInstance (HINSTANCE, int);

} 

Return MSG. WParam; 
} 

Registered wcex will appear after the taskbar ICONS
The flashing news is to use transparent hIcon (should be, because we can't open WeChat kernel view)

CodePudding user response:

This is the kernel code, if the code were not fp output if there is no log
