WM_PSD_FULLPAGERECT
The
WM_PSD_FULLPAGERECT message informs a PagePaintHook hook procedure of the
coordinates of the sample page rectangle in the Page Setup dialog box. The
dialog box sends this message when it is about to draw the contents of the
sample page.
WM_PSD_FULLPAGERECT
hDC = (WPARAM) (HDC) wParam; // handle of the device context
lprcPage = (LPARAM) (LPRECT) lParam; // dimensions
of page rectangle
Parameters
hDC
Value of wParam.
Handle of the device context for the sample page.
lprcPage
Value of lParam.
Pointer to a RECT
structure that contains the coordinates, in pixels, of the sample page.
Return Values
If the hook
procedure returns TRUE, the dialog box sends no more WM_PSD* 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.
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.
