SetCaretBlinkTime
The SetCaretBlinkTime
function sets the caret blink time to the specified number of milliseconds. The
blink time is the elapsed time, in milliseconds, required to invert the caret s
pixels.
BOOL SetCaretBlinkTime(
|
UINT uMSeconds |
// blink time, in
milliseconds |
|
); |
|
Parameters
uMSeconds
Specifies the
new blink time, in milliseconds.
Return Values
If the
function succeeds, the return value is nonzero.
If the
function fails, the return value is zero. To get extended error information,
call GetLastError.
Remarks
The user can
set the blink time using the Control Panel. Applications should respect the
setting that the user has chosen. The SetCaretBlinkTime function should
only be used by application that allow the user to set the blink time, such as
a Control Panel applet.
If you change
the blink time, subsequently activated applications will use the modified blink
time, even if you restore the previous blink time when you lose the keyboard
focus or become inactive. This is due to the multithreaded environment, where
deactivation of your application is not synchronized with the activation of
another application. This feature allows the system to activate another
application even if the current application is hung.
