new time.
The time specified should be between USER_TIMER_MAXIMUM and
USER_TIMER_MINIMUM. If uiParam is less than USER_TIMER_MINIMUM, the
function will use USER_TIMER_MINIMUM. If uiParam is greater than
USER_TIMER_MAXIMUM, the function will be USER_TIMER_MAXIMUM.
Windows Server 2003 and Windows XP: The operating system

|
|
SPI_SETMOUSETRAILS
|

of mouse cursor movements by briefly showing a trail of cursors and quickly
erasing them.
To disable the feature, set the uiParam parameter to zero or 1. To
enable the feature, set uiParam to a value greater than 1 to indicate the
number of cursors drawn in the trail.
Windows 2000: This value is not supported until
Windows XP. |
|
SPI_SETSNAPTODEFBUTTON
|
Enables or disables the snap-to-default-button feature. If enabled, the mouse
cursor automatically moves to the default button, such as OK or
Apply, of a dialog box. Set the uiParam parameter to TRUE to
enable the feature, or FALSE to disable it. Applications should use the
ShowWindow function when
displaying a dialog box so the dialog manager can position the mouse
cursor.
|
|
SPI_SETWHEELSCROLLCHARS
|
Sets the number of characters to scroll when the horizontal mouse wheel is
moved. The number of characters is set from the uiParam
parameter.
|
|
SPI_SETWHEELSCROLLLINES
|
Sets the number of lines to scroll when the vertical mouse wheel is moved.
The number of lines is set from the uiParam parameter.
The number of lines is the suggested number of lines to scroll when the mouse
wheel is rolled without using modifier keys. If the number is 0, then no
scrolling should occur. If the number of lines to scroll is greater than the
number of lines viewable, and in particular if it is WHEEL_PAGESCROLL (#defined
as UINT_MAX), the scroll operation should be interpreted as clicking once in the
page down or page up regions of the scroll bar.
