Routine Description:
Call back used to remove the "?" from the wizard page.
Arguments:
hwndDlg - Handle to the property sheet dialog box.
uMsg - Identifies the message being received. This parameter
is one of the following values:
PSCB_INITIALIZED - Indicates that the property sheet is
being initialized. The lParam value is zero for this message.
PSCB_PRECREATE Indicates that the property sheet is about
to be created. The hwndDlg parameter is NULL and the lParam
parameter is a pointer to a dialog template in memory. This
template is in the form of a DLGTEMPLATE structure followed
by one or more DLGITEMTEMPLATE structures.
lParam - Specifies additional information about the message. The
meaning of this value depends on the uMsg parameter.
Return Value:
The function returns zero.
