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

hDC = (WPARAM) (HDC) wParam; // handle of the device context

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

Parameters

hDC

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

lprcMargin

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.
