This message scrolls a split window in the split details view.
==Syntax==
<PRE>
param1
USHORT usWindow;   /* Window indicator. */

param2
LONG lScrollInc;    /* Amount to scroll. */
</PRE>

==Parameters==
;usWindow ([[USHORT]]) - Input
: Window indicator.
::CMA_LEFT: The left split window is scrolled.
::CMA_RIGHT: The right split window is scrolled.
;lScrollInc ([[LONG]]) - Input
: Amount (in pixels) by which to scroll the window.

==Returns==
;rc ([[BOOL]]) - returns
: Success indicator.
::TRUE: Successful completion.
::FALSE: An error occurred. The [[WinGetLastError]] function may return the following error:
:::PMERR_INVALID_PARAMETERS.

==Remarks==
The '''lScrollInc''' parameter indicates a change in position. If the '''lScrollInc''' parameter value is greater than 0, the window specified in the '''usWindow''' parameter is scrolled to the right by the number of pixels specified in the '''lScrollInc''' parameter. If the value of the '''lScrollInc''' parameter is less than 0, the window specified in the '''usWindow''' parameter is scrolled to the left by the number of pixels specified in the '''lScrollInc''' parameter. This message is used to scroll either the left or right split window by an absolute amount.

The columns that are to appear in each split window are determined at the time the split window is created. Thereafter, columns in the left split window cannot be seen in the right split window, and vice versa.

==Default Processing==
The default window procedure does not expect to receive this message and therefore takes no action on it other than to return FALSE.
