//		4. Add the following message handler to your view class 
//		   When called you get the improved print preview 
// 
//void CYourView::OnFileImprovedprintpreview()  
//{ 
//	// need to use CPreviewViewEx class 
//	CPrintPreviewState* pState = new CPrintPreviewState; 
// 
//	if (!DoPrintPreview(IDD_PREVIEW, this, RUNTIME_CLASS(CPreviewViewEx), pState)) 
//	{ 
//		TRACE0("Error: OnFileImprovedprintpreview failed.\n"); 
//		AfxMessageBox(AFX_IDP_COMMAND_FAILURE); 
//		delete pState;      // preview failed to initialize, delete State now
