If you need to silent print a PDF document from an application, or better through an Adobe Air application you can use the NativeProcess and then call this command. The PDF output format is widely used for publishing digital documents that are exchangeable across platforms while keeping the fidelity of the document's. Introduction. The PDF output format is widely used for publishing digital documents that are exchangeable across platforms while keeping the fidelity of the document's layout, fonts, and other visual styles intact, both on screens and printed media. One obvious example is that most of the US government forms are in PDF format. There are some libraries and technologies that enable the use case that PDF is not just an output format, but works as a data capture (user data input) interface as well. The end user can fill out PDF forms directly within the Adobe Reader, and then submit it online. But, almost all of those approaches are server process oriented, generating PDF streams from the server and sending it down to the client; substantial server side application logics are required to enable using the PDF for data collection. This article provides an alternative client oriented simple approach that blends a PDF and a Silverlight host application in a web browser, eliminating the need for server side logic of assembling user- specific PDF files for data collection. Especially, in the case of a group of PDF forms data that need to be collected, this technique will have higher scalability than the classic server centric technologies, because it makes it possible that the application server only deals with pure data and business logic, no PDF specific logic needs to run on the application server. The downloadable source code has all the details in a working sample; it has a Visual Studio 2. SP1 solution and project files, needs Silverlight 2 Release Candidate 0, and Adobe Reader 8. The Silverlight application, named Silver. Form in the demo project, manages PDF groups as a template list (same for all users), streaming down as a static file from a Web server when the user requests, leveraging the client side Silverlight Plug- in and the Adobe Reader Plug- in to have them work together in a web browser, with tasks like data collection, form navigation, form data persistence, and populating PDF with user data all handled by the client side code. If you have the Silverlight 2 Beta 2 runtime installed, you can run the sample application from here. For developers who have the Silverlight 2 Release Candidate 0 installed, the sample application is here. Both of them share almost the same source code, and require Adobe Reader 8. Overview. The word “blend” here has two- fold meanings, one is to render the PDF on top of the Silverlight hosting application, and reposition/resize the loaded PDF when the Silverlight application layout is updated or resized. Another aspect is to exchange data between Silverlight and PDF; the PDF can notify the hosting Silverlight application that it’s ready to read and populate forms data, and the hosting Silverlight application needs a channel that can request all the user data filled in the PDF and persist/restore them in a client- side isolated storage. The basic idea to render PDF on top of Silverlight is to have a DIV element for positioning in the Silverlight application's hosting HTML code. The content of the DIV is an IFRAME for resizing, while the source of the IFRAME is another HTML file (mqz. PDFContainer. htm, let's call it . The IFRAME content (source) will be positioned and resized exactly based on this control’s position and size. Whenever the user resizes the Silverlight application that results in this “back” User Control’s position or size changing, it would notify the DIV and IFRAME to reposition/resize accordingly via a Silverlight HTML Bridge. When the Java. Script code from the loading HTML (mqz. PDFContainer. htm, it’s the IFRAME’s source) sets up the correct OBJECT or EMBED tag for the PDF file, the browser will take control from there. It would load and instantiate the Adobe Reader, then set the PDF URL as the source of the tag (data attribute in the OBJECT element, src attribute in the EMBED tag). When the Reader loads up, it would start to download the specified PDF file through HTTP. The requested PDF file can reside in the same web server as the Silverlight host application is, all static files - -- - template files that are the same for all users - -- will be downloaded to the client and run within the browser; no application server logic is needed. When the specified PDF is loaded into the Reader, it’ll initiate the data exchange process between the PDF and Silverlight. The data exchange flow is bi- directional, the PDF calls the host. Container. Post. Message to interact with the hosting HTML, and Silverlight application’s managed code invokes the Silverlight HTML Bridge to read and write data. As you can see, the hosting HTML is the middle man between Silverlight and PDF. As a matter of fact, Silverlight managed code never “knows” it’s working with PDF, it only talks with the HTML Bridge. And, PDF never interacts with the managed code directly; all it does is to post and process messages via the host. Container as if there is no Silverlight application around it. To blend PDF with Silverlight visually, with integrated exchangeable data, it’s really a combination of Silverlight, C#, HTML Bridge, Java. Script, host. Container, and PDF. The demo project is built with the thread- safe version of Silverlight Cairngorm. Because of the length of all the details, this article will focus on the plumbing works that connects Silverlight and PDF; the following article will provide points of interests of the demo project that puts all the details together. Blend visually. 1. Create the positioning DIVThe positioning DIV is created by inserting the following HTML code into the hosting HTML code (or the ASP. NET page markup). The hosting HTML file is Silver. Forms. Test. Page. OBJECT tag to create the Silverlight application. The following DIV will be inserted right after the Silverlight OBJECT tag: < !- -- -> < /span> < divid=. Also, the ID of the DIV (mqz. IFrm. Parent) is crucial, because the Java. Script gets the reference of the DIV object using this ID. Create IFRAME and position/size it. All the code that manipulates the properties of the positioning DIV and the corresponding IFRAME is encapsulated in a single Java. Script file: mqz. Js. Calls. js: mqz. Js. Calls = newfunction(). When the Silverlight managed code needs to set/update the position and size of the PDF (Reader), it calls mqz. Js. Calls. move. HTMLZone(x,y,w,h) to reposition or resize it. When a new PDF URL is selected, the managed code will invoke mqz. Js. Calls. show. HTMLZone(true) to make the positioning DIV visible, then call mqz. Js. Calls. set. HTMLZone. Src(pdf. Url) to create the IFRAME as the content of the DIV tag (inner. HTML). We'll examine the SRC attribute in the generated IFRAME tag later in the . Calling mqz. Js. Calls. HTMLZone(x,y,w,h) from the Silverlight User Control. In the demo project, the left hand side is the form navigation panel, implemented by a List. Box and data bound to the form list data. The right hand side is populated by the Content. Zone User Control that serves as the . A Grid. Splitter control sits between the navigation listbox and the content zone, so the user can change the widths of both controls by drag and drop. Also, the user could resize the browser window, which would affect the size of the Content. Zone control. The sole responsibility of the Content. Zone User Control is to handle the Resize and layout. Update Silverlight events, then call mqz. Js. Calls. move. HTMLZone(x,y,w,h) to position and size it correctly: namespace Silver. Forms. View. . Surprisingly, Silverlight doesn't have an API like Local. To. Global or Global. To. Local, we have to rely on the General. Transform object reference of the Root. Visual, then invoke the Transform method to get the global coordinates. Once we get the left- top coordinates and the width and the height, we can invoke the Java. Script method via Html. Page. Window. Invoke. The parameters are passed to the Java. Script through an object array. Load PDF into IFRAMEUp till now, all the plumbing work have been done to load the PDF. The IFRAME tag generated by mqz. Js. Calls. set. HTMLZone. Src(pdf. Url) sets the pdf. Url parameter to the SRC of the IFRAME. In the demo project, pdf. Url is the URL of mqz. PDFContainer. htm, and the PDF file is specified by query string parameters. For example, when the PDF name is ty. Passing the PDF file name in the query string can enable mqz. PDFContainer. htm to just reference the generic Java. Script code to set up host. Container, no form specific code is needed. Here is the HTML code for mqz. PDFContainer. htm: < htmlxmlns=. Both the external Java. Script files are in the demo project, mqz. Query. String. Parser. Url easier. I'll leave the details to the demo project, and focus on the core of the mqz. Load. Extern. PDF. File. Name = find. Query. String(. 1). Load. Content is wired up with the HTML page onload event, it calls Load. PDFFile(pdf. File. Name) when the HTML loads into the IRFRAME. Inside the Load. PDFFile(pdf. File. Name) function, it creates an OBJECT tag for IE, Firefox 2. Safari (type=application/vnd. EMDED tag for Firefox 3. Once the OBJECT tag or EMBED tag are set to the inner. HTML of the empty DIV, the web browser will start instantiating the Adobe Reader plug- in, and the plug- in will load the PDF specified in the data (of the OBJECT tag) or the SRC (of the EMBED tag) attribute. The end result is the PDF is rendered on top of Silverlight, on the exact location and size of the Content. Zone control - -- - visually blended. Data exchange between Silverlight and PDFThe data integration work has four important tasks: PDF notifies the host that it's ready to take data. Host sends data to PDF. Host notifies PDF it needs user data. PDF formats the user data and sends it back to the host. Let's look at them one by one. Before any . The message handler needs to be set up in the loading HTML.
