Hello! How to create a form with . pdf and . doc reader? like a library. . . I want to open the . pdf and . doc files on the form. I work on Visual Studio C++ (CLR).
Search for OLE on MSDN (Object Linking and Embedding). You might already have the Acrobat plugin installed - it's the "feature" that means whenever you click a PDF online, you get the PDF displayed in the browser (so you get the PDF window with the browser's menu - I've never been able to see the point of that, but apparently people wet themselves about it so it must be good), so you also need to find a similar plugin for DOC files (by which do you mean Microsoft Word? It's not the only word processor to use the DOC extension).
Foxit Reader is good software for PDF reader but if you want PDF writer or editor then code origami is the best software.
