WM_INITSECONDARYWINDOW

This message occurs when a secondary window is being created.

Syntax

param1
     [[ULONG]]  [[ulReserved]] /*  Reserved. */

param2
     [[PVOID]]  [[pcreate]]    /*  Application-defined data area. */

Parameters

ulReserved (ULONG)

Reserved value. Set to zero.

pcreate (PVOID)

This points to the data area that is passed by the WinLoadSecondaryWindow, WinCreateSecondaryWindow, and WinSecondaryWindow functions in their pCreateParams parameter.

Return Value

Remarks

This message occurs after the WM_INITDLG message and after the secondary window is set to its initial size. Application sizing adjustments should be made with this message, rather than with WM_INITDLG.
