Delphi TAcroPDF - 禁用保存按钮、工具栏面板和右键单击弹出菜单

Question

I am working with strong restricted environment. Application can show PDF files inside window, but I would like to disable some features: - save button - show toolbar Adobe Reader button - right click mode - use only hand tool

The PDF file should be only in ReadMode, with possibility to print.

I am used "#toolbar=0&navpanes=0" as parameter, but toolbars could be activated by right click.

Any ideas or other, more flexible and free library for PDF ?

Windows 7 x64, Delphi Seattle Adobe Reader XI

I'm posting this as an answer partly because there is more to say than will fit in a comment.

Firstly, iirc, the automation of Acrobat Reader was only ever intended to assist it being embedded in IE and, over the years, there have been some changes which were apparently intended to restrict other use (even supposing your current Reader licence permits it).

Anyway, in your position, I would implement the PDF functions by calls to the PdfTK utility

https://www.pdflabs.com/docs/pdftk-man-page/

having checked its licence of course.

I've always found PdfTK to be ultra-reliable and it can do things that even the automation library of the full Acrobat cannot, like "flattening" PDF documents, properly embedding watermarks, etc.

Btw, PdfTK is a command-line utility and operates on files, so requires access to a file system, which may of course rule it out for your situation.
