The message means a notification issued by Windows to tell the application a matter. For example, click the mouse, change the window size, press a key on the keyboard to send Windows to your application.
The message itself is passed to the application as a record, and this record contains the type of message and other information. For example, for messages generated by clicking on the mouse, this record contains the coordinates when clicking the mouse. This record type is called TMSG, which is declared in the Windows unit:
Type
TMSG = Packed Record
HWND: hwnd; // window handle
Message: uint; // Message constant identifier
WPARAM: WPARAM; / / 32-bit message Specific additional information
LPARAM: LPARAM; / / 32-bit message Specific additional information
Time: DWORD; // Message time
PT: tpoint; // Message Mouse position
END;
What is there in the news?
Do you feel that the information in a message record is like Greek? If this is the case, then take a look at the explanation below: HWND 32-bit window handle. The window can be any type of screen object because Win32 can maintain most
The handle of the object (window, dialog, buttons, edit box, etc.). Message is used to distinguish constant values for other messages, which can be predefined in the Windows unit,
Can be a custom constant.
WPARAM is usually a constant value related to messages or a handle of a window or control.
LPARAM is usually a pointer to data in memory. Because WPARAM, LPARAM and POIIters are 32-bit, they can be converted between them.
