WM_PSD_MARGINRECT
The
WM_PSD_MARGINRECT message notifies the hook procedure of a Page Setup dialog
box that the dialog box is about to draw the margin rectangle of the sample
page.
WM_PSD_MARGINRECT

lprcMargin = (LPARAM) (LPRECT) lParam; // margin
rectangle

hDC
Value of wParam.
Identifies the device context for the sample page.

Value of lParam.
Pointer to a RECT
structure that contains the coordinates, in pixels, of the margin rectangle.
Return Values
If the hook
procedure returns TRUE, the dialog box does not draw the margin rectangle in
the sample page.
If the hook
procedure returns FALSE, the dialog box draws the margin rectangle in the
sample page.
Remarks
The Page
Setup dialog box includes an image of a sample page that shows how the user s
selections affect the appearance of the printed output. When you call the PageSetupDlg
function, you can provide a PagePaintHook hook procedure to customize
the appearance of the sample page. Whenever the dialog box is about to draw the
contents of the sample page, the dialog box sends a sequence of WM_PSD*
messages to the hook procedure.
