   Joe:

I have not created a stand-alone viewer per se'... and I've used different types of viewers depending upon the project.  All these are in huge projects so it would not be a trivial task to send you something.

I've only used QuickPDF for simple page preview.  I've also used the GdPicture component for PDF viewing... it is a higher level viewing tool, but costs money since it's a commercial tool.  Also have used AcroPDF.dll  provided by Adobe, embedded in some projects.  That one requires the end-user has Adobe Reader installed which is not usually an issue.

To view PDF's with QuickPDF you would need to render the PDF content to an image object and display the image.  If you want to create a full blown viewer with all the bells and whistles, (rotate, zoom, paging, scrolling, etc) you're probably better off with a higher level language tool like GDPicture Viewer or the free AcroPDF.dll from Adobe.

	Hey Joe: You can open/view PDF's with livecycle features... you just can't use the features or edit the document. If you attempt to edit a Livecycle PDF form field it won't work. If you attempt to append a page to a Livecycle PDF the Livecycle features will no longer work. You'll get all kinds of warning messages in Adobe Acrobat & Reader. And Yes... NO other 3rd party developer can access or process Livecycle features. It is Adobes attempt to recapture market share they've lost to others over the years. I think you'll find the majority of the PDF world still uses the Acroforms or XFA forms format which is supported in QuickPDF Library. If you must process or create PDF's with Livecycle features then you are stuck with Adobe Products only. Regarding a PDF Viewer, what language are you using. Tom

	Hi Joe: The QuickPDF Library is one of the most complete libraries on PDF you'll find. It has dozens of functions for creating, filling, editing, flattening, etc., form fields. See this link: http://www.quickpdflibrary.com/help/quickpdf/FormFields.php For Javascript see this link: http://www.quickpdflibrary.com/help/quickpdf/JavaScript.php What Ingo was talking about are PDF's created with LiveCycle advanced features. Live Cycle is a proprietary format owned exclusively by Adobe. No one... not FoxIt, Nitro, or QuickPDF can edit or use the Live Cycle features. Adobe owns it and is not sharing with anyone. I hope this better answers your questions. Tom

	hi Ingo hope you had a merry xmas this restriction you mentioned i tried out and as usual Adobe is trying to make it all too difficult for everyone however this will not be a problem for me as my custom viewer will be in my application so it will be used as the main pdf viewer and no need to use adobe free reader i hope you can answer my question - can i by using the quickpdf library create a reader like foxit that i can edit/enter the formfields or is it just a viewer without any editing functions cheers joe

	Hi Joe! Please read my blog at: http://pdfcomments.blogspot.com/2009/06/pdf-and-forms.html Sorry... but i can only say f...k you adobe and f...k you livecycle. Good products but very expensive and adobe had done a lot to be sure that the customers have to buy adobe products .-( Do some modifications on forms made by newer adobe products and it will be impossible to work on these forms with adobe reader or other adobe products anymore. This has nothing to do with QuickPDF ... it's the same with any other external third party tools. Cheers, Ingo

	Hey Joe ;-) You can find a pb-sample with qp here: http://www.powerbasic.com/support/pbforums/showthread.php?p=311765 Here in the sample section you'll find vb6-code as well. With a real viewer you shouldn't expect big compatibility problems. Perhaps advanced adobe-functionalities you'll missing. If you want to modify an adobe livecycle form with an external third party product then the problems will raise and raise but only for a viewer you can use QuickPDF. It's not very difficult... read the file into a stream... render stream to image... put the image on a picture-component... Cheers, welcome here and Merry Christmas for you and your family

	hello i am new to this forum. we are valuating this product with a view to creating a custom viewer. has anyone already created a viewer if so would it be possible for us to get a copy of it as we have PDF files that have been created with adobe livecycle and what we to do is to see if there are any compatibility issues. thanks joe@csolutions.com.au
