PSM_RECALCPAGESIZES message

Recalculates the page size of a standard or wizard property sheet after pages have been added or removed. You can send this message explicitly or use the PropSheet_RecalcPageSizes macro.

Parameters

wParam

Must be zero.

lParam

Must be zero.

Return value

Returns TRUE if successful, or FALSE otherwise.

Remarks

When a property sheet is created, it is sized to fit its initial collection of pages. In order to maintain compatibility with previous versions of the common controls, property sheets and wizards do not automatically resize themselves when pages are subsequently added or removed. With common controls version 5.80, applications should send a PSM_RECALCPAGESIZES message after adding or removing pages with PSM_ADDPAGE, PSM_INSERTPAGE, PSM_REMOVEPAGE, or their equivalent macros. It ensures that the property sheet is properly sized for its current collection of pages. If this message is not sent, some property sheet pages may be truncated or too large.
