WM_PSD_ENVSTAMPRECT message

Notifies the hook procedure of a Page Setup dialog box, PagePaintHook, that the dialog box is about to draw the envelope-stamp rectangle of the sample page.

#define WM_USER                  0x0400
#define WM_PSD_ENVSTAMPRECT     (WM_USER+5)

Parameters

wParam

A handle to the device context for the sample page.

lParam

A pointer to a RECT structure that contains the coordinates, in pixels, of the envelope-stamp rectangle.

Return value

If the hook procedure returns TRUE, the dialog box does not draw the envelope-stamp portion of the sample page.

If the hook procedure returns FALSE, the dialog box draws the envelope-stamp portion of 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 messages to the hook procedure.

A hook procedure receives this message only if the selected paper type is an envelope.
