  6. Silverlight Printing API • Print must be started by a user interaction • Printer selection dialog is shown in any case • So always similar to … TO PRINTER PROMPT • Migration of VFP reports possible

  7. Silverswitchreports • ProductsTemplate.frx • Migrated to: • ProductTemplate.xaml • DataGrid reports

  16. FRX with VFP COM server • Create URL of PDF file string pdfPageURL = applicationUrl+ "UploadedFiles/" + vfxCreatePDFActionButton.OperationResult.result;

  17. FRX with VFP COM server • Open PDF in new browser window System.Windows.Browser.HtmlPage.Window.Navigate( new Uri(pdfPageURL, UriKind.RelativeOrAbsolute), "_blank", "toolbar=no, location=no, status=no, menubar=no, resizable=yes"); }
