What is the value of HSHELL_FLASH
回答1:
Assuming you meant the actual integer value, HSHELL_FLASH is defined in WinUser.h as
#define HSHELL_FLASH (HSHELL_REDRAW | HSHELL_HIGHBIT)
where
#define HSHELL_REDRAW 6
#define HSHELL_HIGHBIT 0x8000
thus the actual value is 0x8006.
回答2:
The value is 42.
Just kidding.
By "value" I'm assuming you're looking for a basic explanation of what this variable represents. HSHELL_FLASH is a handle to a window that needs to be flashed.
HSHELL_FLASH should be treated similarily to HSHELL_REDRAW, except that you should redraw it in a flashed state (normally orange on the Explorer taskbar). HSHELL_REDRAW means that either a window's title text has changed, or the window's icon has changed.
