WM_PSD_FULLPAGERECT Overview  Group

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.
