Notifies a PagePaintHook hook procedure of the coordinates of the margin rectangle in the sample page. A Page Setup dialog box sends this message when it is about to draw the contents of the sample page.
#define WM_USER 0x0400 #define WM_PSD_MINMARGINRECT (WM_USER+2)
A handle to the device context for the sample page.
A pointer to a RECT structure that contains the coordinates, in pixels, of the minimum margin rectangle.
If the hook procedure returns TRUE, the dialog box sends no more messages and does not draw in the sample page until the next time the system needs to redraw the sample page.
If the hook procedure returns FALSE, the dialog box sends the remaining messages of the drawing sequence.
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 messages to the hook procedure.
