Looking for a control to view and edit PDF

Q: I’m looking for a control that I can use in my app that will allow
a existing pdf file to be opened and text inserted at a specific
location. This will all be done by the program not by the user
interacting with the control. Do you provide a control that will do
this.

A: You can use PDFNet SDK (http://www.pdftron.com/pdfnet) to implement
this requirement. You could use PDFViewCtrl to open and view an
existing document and ElementBuilder/ElementWriter to stamp pages with
new content.

As a starting point you may want to take a look at the following
resources:

PDFView sample: http://www.pdftron.com/pdfnet/samplecode.html#PDFView
PDFViewSimple sample: http://www.pdftron.com/pdfnet/samplecode.html#PDFViewSimple

To add new content to existing PDF page see:
  "How do I add a watermark to a page?" in http://www.pdftron.com/pdfnet/faq.html

This can also be done interactively to existing document opened in
PDFViewCtrl.

For info on how to edit or add new content to a document opened in
PDFViewCtrl, please see

"How do I refresh PDFViewCtrl after adding new content to a PDF page?"
