Hi You can instantiate the SaveFileDialog, then you can filter it to any document you want in your case its PDF. Here is the green light. The PDF document can be generated from the print document by using the PdfImage class. Refer the code example and sample below for the. I was looking at a way to convert Printdocument inormation into PDF or Is it possible, in scretch.info code, to send the content of a Printdocument.

scretch.infong Private WithEvents p_Document As PrintDocument = Nothing Private Sub . I used this code to print my PDF files on VB NET. PrintFileName = "c:\ztrash\scretch.info" So, i've created a small "hello world" app to test using the new PrintDocument object for Specialising in Visual scretch.info & Client Server Programming & Client/Customer Relations. Thank you All for your friendly help. Hi dleece, Welcome to MSDN forums! If you want to simply print a pdf document in scretch.info, then here is the.
NET This content is based on version At the time of writing, it has not been released. Please contact us if you want to have a beta of that version to work with ASP. It is very common that we hear from VB. NET applications.
Start "TestDocument. To achieve text wrapping one must manually measure the lengths of strings and wrap the text accordingly. Furthermore, the current document y position must also be tracked as rendering is performed. In this simple example tracking the y position is trivial, although rendering does become slightly more challenging when more complex rendering is performed e.
Migradoc Re-generating the above document in Migradoc is useful for demonstrating both the pros and cons of each library. Unlike PdfSharp, Migradoc uses a Document object to which document elements e. The document is rendered using a PdfDocumentRenderer.
However, complications arise when one tries to do anything out of the ordinary. Similarly, there is no way to position the table in a specific location i. However, Migradoc does perform text-wrapping for us, which is clearly beneficial when rendering large amounts of text. GetPageSize PageFormat.
AddSection ; section. AddColumn width ; column. Cells; cell. Black; cell. ApplyFont font ; cell. AddParagraph "Hello, World! Left; cell.
However, do keep in mind that mixing both libraries is also possible see the PdfSharp Samples project or here for an example. Correspondingly, part of my investigation focused on the printing aspects of PdfSharp, for which I identified two options.
When printing in this way the PdfFilePrinter invokes the Adobe Acrobat reader, but unfortunately this also has the side effect of opening the PDF file in an Adobe window while printing. I was unhappy with this side-effect and looked inside the PdfFilePrinter class to see if the operation could be tweaked.
I identified a number of flags that could be passed to Adobe Reader to requestthat it hide its window while printing, although experimenting with these flags did not yield a better experience. I don't believe I ever succeeded in getting Adobe to respond to all of the parameters specified.
Unsatisfied with the above approach I investigated further options for PDF printing. The next technique actually comes from within the Migradoc library MigraDoc. MigraDocPrintDocument itself and is the approach I recommend. The class provides a simplified printing process for MigraDoc documents and fundamentally, it integrates with the. NET framework. This is a greatlittle feature, and incidentally, is not one that is present in iTextSharp. There are two steps to printing a PDF document using this approach.
The first step is to obtain the target printer settings. This can be done using a PrintDialog as shown previously. However, the key difference from the previous approach is that we now utilise a PrintDocument object rather than a PdfFilePrinter. PrinterSettings; printDoc.
The code extract below shows that the PrintPage delegate is called with a set of System. PrintPageEventArgs, from which a System. Graphics objects can be extracted. During this process we ensure that the graphics context is trimmed to adhere to any physical limitations of the printer, which can be determined by calling the Windows API function GetDeviceCaps.
One can then render to the XGraphics object in the same way irrespective of whether the source is a PDF document, printer or screen. It is important to note that we set the 'HasMorePages' property of the PrintPageEventArgs before the method exits because this property it used to determine when printing is complete. The PrintPage event will continue to be raised until this property is set to false and thus it is essential that you can determine when your rendering process is complete.
DpiY; graphics. Landscape is true. FromGraphics graphics, pageSize ; e. As mentioned earlier, the two libraries can be jointly employed to render a single document, however, there seems to be some incompatibility between each library's core document object which means some components of Migradoc cannot be used under some conditions.
For example, I wanted to use PdfSharp to construct a document and to then use the document preview User Control provided by Migradoc. When rendering a document with PdfSharp a PdfSharp. PdfDocument object is used, however, MiigraDoc uses the Migradoc.
Document object and the preview control requires such a document. Because PdfSharp does not use a document object model you can render anything anywhere , there is no way of converting from one document type to another and thus one cannot utilise the Migradoc preview control in this way. However, PrintPreviewDialog has some shortcomings, including the following: The entire document must be rendered before the preview appears.
This is annoying for long documents. There are no options for choosing the printer, adjusting the page layout, or selecting specific pages to print. The dialog looks outdated. It hasn't changed since. NET 1. The dialog allows little or no customization. There is no option to export the document to other formats such as PDF. Page images are cached in the control, which limits the size of the documents that can be previewed.
The CoolPrintPreviewDialog class presented here addresses these shortcomings. It is just as easy to use as the standard PrintPreviewDialog, but has the following enhancements: Pages can be previewed as soon as they are rendered.
The first page is shown almost instantly and subsequent pages become available while the user browses the first ones. The "Print" button shows a dialog that allows users to select the printer and page ranges to print. A "Page Layout" button is also available so users can change page size, orientation, and margins.
The dialog uses a ToolStrip control instead of the old toolbar. You have the source and can customize everything from appearance to behavior.
The control creates a list of images which can be exported to other formats including PDF. You instantiate the control, set the Document property to the PrintDocument you want to preview, then call the dialog's Show method.
If you have code that uses the PrintPreviewDialog class, switching to the CoolPrintPreviewDialog only requires changing one line of code. The PrintDocument object has a PrintController property that specifies an object responsible for creating the Graphics objects where the document is rendered. The default print controller creates Graphics objects for the default printer and is not interesting in this case. These remain available to the caller to be shown in the preview area.
The CoolPreviewControl works by temporarily replacing the document's original print controller with a PreviewPrintController, calling the document's Print method, and getting the page images while the document is rendered. The images represent pages in the document, and are scaled and displayed in the control just like any regular Image object.
Clear ; doc. When the Print method is invoked, the document starts firing events. The PrintPage and EndPrint event handlers capture the pages as soon as they are rendered and add them to an internal image list.
The event handlers also call the Application. DoEvents method to keep the dialog responsive to user actions while the document renders. This allows users to switch pages, adjust the zoom factor, or cancel the document generation process.
Without this call, the dialog would stop operating until the whole document finishes rendering. Add pageInfo[i]. The rest is concerned with housekeeping tasks such as scaling the preview images, updating the scrollbars, handling navigation buttons, mouse, keyboard, and so on. Please refer to the source code for the implementation details. Updating the Page Layout The preview dialog allows users to update the print layout.
This is very easy to implement, thanks to the. Changes made by the user are reflected in the document's DefaultPageSettings property. If the user clicks OK, then we assume that the page layout has been modified, and call the RefreshPreview method on the preview control.
This method regenerates all preview images using the new settings, so the user can see the changes applied to margins, page orientation, and so on. Printing the Document When the user clicks the "Print" button, the dialog shows a PrintDialog so the user can select the printer, page range, or change his mind and cancel the printing.
Unfortunately, page range selections are not honored if you simply call the Print method directly on the document.
To remedy this, the dialog calls the Print method on the enhanced preview control instead. That implementation uses the page images already stored in the control, and honors page ranges defined in the document's PrinterSettings properties. PrinterSettings; ps. This may be the full document, a specific range, or the current selection page being previewed.
