WM_PSD_ENVSTAMPRECT
The
WM_PSD_ENVSTAMPRECT message notifies the hook procedure of a Page Setup dialog
box that the dialog box is about to draw the envelope-stamp rectangle of the
sample page.
WM_PSD_ENVSTAMPRECT
hDC = (WPARAM) (HDC) wParam; // handle of the device context
lprcEnvStamp = (LPARAM) (LPRECT) lParam; //
envelope-stamp 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 envelope-stamp
rectangle.
Return Values
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 WM_PSD*
messages to the hook procedure.
A hook procedure
receives this message only if the selected paper type is an envelope.
