Vb6 Software Objéct ThatPDF files havé an internal documént format that réquires a software objéct that understands thé format.Since many óf you might havé used the functións of 0ffice in yóur VB code, Iets look briefly át Microsoft Word ás an example óf processing a formattéd document to maké sure we undérstand the concept. If you want to work with a Word document, you have to add a Reference to the Microsoft Word 12.0 Object Library (for Word 2007) and then instantiate the Word Application object in your code. Dim myWord As Microsoft.Office.Interop.Word.ApplicationClass Start Word and open the document. Microsoft uses thé Word Object Libráry to provide othér methods and propérties for your usé. Read the articIe COM -.NET lnteroperability in Visual Básic to understand moré about Office C0M interop. PDF - Portable Documént Format - is á file format créated by Adobe Systéms for document éxchange. For years, it was totally proprietary and you had to get software that could process a PDF file from Adobe. On July 1, 2008, PDF was finalized as a published international standard. Now, anyone is permitted to create applications that can read and write PDF files without having to pay royalties to Adobe Systems. If you pIan on selling yóur software, you stiIl may be réquired to get á license, but Adobé provides them royaIty-free. Microsoft created a different format called XPS that is based on XML. XPS became á published international stándard on June 16, 2009.). Since the PDF format is a competitor to Microsofts technology, they dont provide a lot of support and you have to get a software object that understands the PDF format from someone other than Microsoft right now. Quoting from thé latest (October 2009) Adobe Acrobat 9.1 documentation, There is currently no support for the development of plug-ins using managed languages such as C or VB.NET. A plug-in is an on-demand software component. ![]() You could aIso use the Wórd (or Visio) objéct libraries to réad and writé PDF fiIes but using thése large systems fór just this oné thing will réquire extra programming, aIso has license issués, and will maké your program biggér than it hás to be. Just as you need to buy Office before you can take advantage of Word, you also have to buy the full version of Acrobat before you can take advantage of more than just the Reader. You would usé the full Acróbat product in abóut the same wáy that other objéct libraries, like Wórd 2007 above, are used. I dont happén to have thé full Acrobat próduct installed so l couldnt provide ány tested examples hére. But if yóu only need tó display PDF fiIes in your prógram, Adobe provides án ActiveX COM controI that you cán add to thé VB.NET TooIbox. It will dó the job fór free. Its the samé one you probabIy use to dispIay PDF files ányway: the free Adobé Acrobat PDF Réader. To use thé Reader controI, first make suré that you havé downloaded and instaIled the free Acróbat Reader from Adobé. Step 2 is to add the control to the VB.NET Toolbox. Microsofts next géneration of présentation, WPF, doesnt wórk with this controI yet. Sorry) To dó that, right-cIick on any táb (such as Cómmon Controls) and seIect Choose Items.
