I'm developing an add-in for Office applications (primarily Word and PowerPoint) using the Common API for Office, and I need to be able to insert videos into the current selection. In the future, I want to be able to insert audio-clips too.
Currently, I have been able to insert images using the setSelectedDataAsync(data, options, callback) method. As far as I can tell, there's no suitable coercion type in the Office.CoercionType enum that supports videos, and I've had no luck omitting the 'options' argument. It would probably be possible to use the Open Office XML format, but it seems like this is only supported in Word. Is there any way to insert videos (and potentially audio-clips too) in both Word and PowerPoint using the Common API for Office?
not this is not possible. In Word you can insert the OOXML coercionType, however that is not supported for PPT.
Is it possible to disable the copy option of the lib when selecting a text in the PDF using the PDFTron lib for Android?
I tried to search for the string, but also have not found it.
If you are using one of the mobile SDK's, or using our PDFViewWPF control for .Net 4+, then this is possible by modifying the tools code that is provided. There will one or two text selection tools, for which you can just comment out. Plus you would want to disable ctrl-c, and right click and select copy abilities. Exact code changes depends on platform. If you are using our older C++ PDFViewCtrl class this is harder to do, but I suspect you are not on this anyway.
Be aware though, there is no real way to prevent a user from extracting text from a PDF, since they can always open it in another PDF viewer and do it there.
See this form post for more info, including how to scramble the unicode values of text.

Note, you will probably be interested in the PDFTron WebViewer technology, which provides much greater control over content. In particular, the original PDF file is never exposed to anyone for download. You can also encrypt the XOD file, so it cannot be opened in an XPS viewer, and you have full control over the UI, including disabling text search/extraction.

Is it possible to extract, modify or simply read text in an Office while user types in words? It it possible through OpenXML SDK & InterOp library?
Thanks.
I have used the Microsoft Office Interop API for Word in a couple of projects, and surely, you can access the content of the document, even while a user is editing it.
I suggest you take a look at some tutorials to get you started, and if you encounter some problems, you can always return and ask.
Beware though - if you are expecting to be able to read the content each time a new character or word has been entered in the document, you might get disappointed, as there currently are no events raised when this happens.

Ok, I've seen a few posts that mention a few other posts about not using SP wikis because they suck.
Since we are looking at doing our wiki in SP, I need to know why we shouldn't do it for a group of 6 automation-developers to document the steps in various automated processes and the changes that have to be made from time to time.
Here are some caveats I came across that will vanish if you use a wiki other than Sharepoint.
Sharepoint lets you create tons of separate wikis, but I'd recommend having one big wiki for everything. My company made a bunch of little wikis for each project/feature, but only admins can create the individual wikis, so if I want to write about something that isn't doesn't match one of the predefined categories, I have to find a manager to create the wiki first.
Secondly, if you use Sharepoint make sure everyone on your staff only uses IE, since Firefox doesn't support the WYSIWIG editor. This is a good thing for most wikis, but makes collaborating difficult in Sharepoint. Imagine editing auto-generated HTML in a tiny little box all day.
Third, try to write up your project documentation in the wiki and resist the temptation to upload Word docs to the Sharepoint library. No point in writing up all your docs twice and watching things get more and more out of sync.
Finally, image support in Sharepoint wikis is terrible. You have to add a file to a document library somewhere and type in the URL. My images were forever getting deleted because they don't seem to make much sense out of context.
I have a much more positive view of Microsoft's Sharepoint Wiki. In many ways it reminds me of FrontPage 98 -- and that was an unfairly maligned product.
The comment about using a list is misguided. Sharepoint Wikis ARE Sharepoint lists, in which each page is a list item with an HTML attachment.
It's true that you can't link into a page, but if the pages are short I don't see that as a problem. SP Wiki makes it very easy to have short pages.
You can manipulate the Wiki attributes from access 2008 if you wish, and you can add attributes to the wiki list items as desired. For example -- do you want categories? Just add them by editing the list. Want specific views? of list items. Create them too.
There's real genius in the way Microsoft built their Wiki framework atop Sharepoint lists -- which are undeniablly well done.
The TRUE drawback of Sharepoint Wiki was mentioned by famerchris. The approach to image management is surprisingly awful. It's such a serious problem that you should consider other Wikis for this reason alone.
There is a convoluted workaround that I use. It takes advantage of the superb Sharepoint support and image editing integrated with Windows Live Writer.
Create a SP blog that will hold the images that will be referenced in the wiki.
Use Windows Live Writer to post to the wiki-image-blog. Drop your image into WLW, resize it as needed, etc. If you like, use WLW to write your image associated wiki text first draft as well.
After you post to the Wiki, copy and paste image and text into the Wiki editor rich text field.
This takes suprisingly little time, far less than any other option I've read of. I admit, it is convoluted.
Other than the image problems I'm pleased and impressed with the product. If only Microsoft had thought harder about images ... if only ...
The default wiki included with Sharepoint doesn't support common wiki features well at all. There is no way to edit a single section of a page, and no way to link directly to a particular section on another page. The backend is in HTML so you lose the ability to edit in plaintext using simple syntax. The diff feature can't span multiple versions. Poor cross browser support of WYSIWYG editing. No way to auto-insert a table of contents...
There are, however, other wiki add-ins for Sharepoint which I can't categorically dismiss, for instance Confluence makes an add-in for Sharepoint. I haven't evaluated this software myself, and Confluence is somewhat expensive ($1,200 for 25 user license) although if you are already on Sharepoint I sense large corporate coffers :P. There also appear to be some free add-ins like CKS Enhanced Wiki but that appears to have a lot of the same problems mentioned above.
We run into this topic all the time, and the first question I have taken to asking people is "Why do you need a wiki"? Almost always the answers are things "ease of editing", "multiple contributors", and "Word is to heavyweight". Very rarely have we seen anyone ask for what I consider to be uniquely wiki-like features (special "magic" markup, fine grained version history showing changes, etc). Also, they usually want some kind of categorization of things, not just completely free-form pages.
In the SharePoint world these things should scream "list" at you if you've been working with the tool for a while. There is basically no particular reason to use a wiki for these knowledge base-style applications, especially since "ease of editing" usually directly conflicts with the idea of learning a special markup language for most user. Through a couple of rich-text columns in there, and you're all set. If you really don't like the built-in rich-text editor (yes the image uploading process is clunky and it doesn't work in Firefox), have someone in your organization go drop the 8 Benjamins and go get the RadEditor for SharePoint. It should pretty much handle those concerns.
Generally once we've gotten over the "but it needs to be a wiki" dogma, we've had pretty good customer reception to just using lists. In some cases, where a little more of a page templating facility was required we turned to using the WCM features of MOSS, which requires a little more up-front thought about templates, but also has a better out of the box experience for things like content snippets and image handling.
Because the default implementation is not a wiki, it is an HTML editor.
If you've used a wiki before you'll know the difference. Just look at "Your answer" at the bottom of this page to see the difference. You use markup in a wiki, which is relatively easy to read and edit. Formatted HTML completely obscures what is written.
My two cents worth as a wiki content creator and super-user, rather than an administrator or developer:
I am currently editing a document in Sharepoint Wiki as I type this, and it is by far the worst editor I have ever come across. To be precise, I'm using Sharepoint Foundation 2010 (previously known as WSS), editing pages using IE 9.
To sum up the problems I've faced: When creating wiki content you want to concentrate on the content and the wiki engine should be so easy to use as to be almost invisible. With Sharepoint that is not the case. I really struggle with the pseudo-WYSIWYG editor, having to fix frequent formatting problems.
I estimate that I'm about 15% less productive writing wiki content with Sharepoint than I am with ScrewTurn or Wikimedia because I have to deal with the formatting issues. If I spend a day writing wiki pages I would lose about an hour trying to fix formatting issues.
For background: I've created four internal wikis at our company - the first in Wikimedia, the wiki engine behind Wikipedia, the next two in ScrewTurn, and a final one in Sharepoint. In each wiki I've written about 50-100 pages.
In both ScrewTurn and Wikimedia the editor looks fairly primitive - a plain text editor that uses simple wiki mark-up codes for formatting. Each has a row of buttons that can apply mark-up codes for simple things like bold and italic formatting, and to create links, so beginners do not need to learn the mark-up codes by heart. While the editors look plain they turn out to be really simple to use, especially for fixing formatting problems.
Sharepoint Wiki, on the other hand, looks slick but is terrible for editing. Instead of using a plain text editor with wiki mark-up it has a WYSIWYG editor that looks much more sophisticated than other wiki editors. However it has personality, an evil one. It frequently adds blank lines or changes the colour of text. When I select text to format then go to the Markup Styles dropdown to format it, sometimes the act of selecting an item from the dropdown list deselects the selected text so the formatting applies to text at a random location. Inserting text copied from Word sometimes causes the editor to double or triple up on blank lines between paragraphs at other places on the page. There appears to be no easy way of creating a table, apart from writing HTML.
The biggest problem about the editor, however, is that you can't easily see what is going on behind the scenes so it's difficult to fix it. Yes, it's possible to edit the page's HTML but that really defeats the purpose of a wiki.
The overall impression I get as a user, is that this is alpha-level code that has been knocked up by a summer intern. I know Foundation is the free version so perhaps I get what we've paid for but I cannot believe a professional software company put out this product.
For a group of 6 people that will be making "every now and then" edits, the built-in wiki will be fine.
The Sharepoint Wiki is essentially a list of Static HTML Pages, with the only Wiki-feature being [[article]] links. No Templates, No Categories, nothing.
We ended up having a separate MediaWiki and only use the Sharepoint wiki for text-based content that does not need much layout.
Don't forget the Community Kit for Sharepoint - Enhanced Wiki Edition. This adds some features to the out of the box version.
Before the rant, here is my overall experience with SharePoint as a wiki.
It is a poorly implemented feature that failed becouse there was a fundemental lack of investigation into what current wiki environments provide. That is why it failed in it's editor and why it misses on points like: tagging, history comparison, and poorly generated html code.
You need to skip it and get something else that does the job better and link to it from SharePoint.
Having production experience with both products, I'd recommend ScrewTurn over SharePoint.

My company rolled out sharepoint recently, and I have to say my user experience was Very Bad. And I'm not just saying I was apprehensive to using it: I went in with an open mind and tried it, and many things just felt like they didn't really work right.
The reasons Luke mentioned more or less cover it.
Why wouldn't you consider using something else like Screwturn Wiki which Jeff donated to a short while ago? I haven't used Screwturn myself, but it is free and open source, and may be a faster lightweight solution for what you need.
We looked at Sharepoint for a department wiki a few months ago. Even though we're primarily an MS shop, we went with DokuWiki. Open-source, so easy to keep up to date, great plugins, and a file-based back end.
I would also temper the ratings of the OOB wiki and its lack of functionality with the technical level of the authors here.
I agree that the SP wiki might qualify in name only - certainly when compared to some more robust offerings - but remember as an admin - your primary success is determined by end user adoption. In short - for every feature that a wiki like Confluence adds, it also adds user education, syntax, etc.
While I would love SP wiki to have more "wiki-like" - there is a certain, undescribable satisfaction you can take when your CIO adds an entry in the company wiki - or you are recognized by a group of administrative assistants who find the new wiki "revolutionary".
In short - the built in functionality may be lacking to the jaded eyes of us tech professionals, but to the technologically naive, its pretty easy to train on, and can expose them to a technology they may have heard of but could never (before this) understand or imagine using.
I've played very briefly with SharePoint Wiki Plus. It's a third-party extension that adds features to the SharePoint Wiki. For serious wiki users then you probably need something more than the SharePoint provided Wiki - either via an extension or a dedicated Wiki product.
Maybe try http://wordtosharepoint.codeplex.com/ for migrating your Word content to SharePoint? It takes care of linking images and most other things.
Screwturn is wicked awesome - and it is C# / .Net.
Sharepoint 2010 is supposed to have better wiki features, and there is always the community kit of sharepoint.
If you are able to leave the Sharepoint Wiki behind - you could always head over to the http://www.wikimatrix.org to find the wiki that works for you.
I fully concur with the above (Keng). Whatever that thing is within SharePoint (currently using 2010), it is NOT a Wiki by a long shot.
I am implementing an automated documenting solution, where I extract config and other info (like perldoc markup) from source code and XML config files. It inserts the info in a set of DokuWIKI pages, complete with formatting markup (including tables). It comes out perfectly formatted and works with a couple of tens of lines of perl, includes internal links to manually edited static doc pages, and support for namespaces so I can have my information logically organised. There is no way I could do that in SharePoint (sigh - company direction)...
The best I can do is try to make DokuWIKI template resemble sort of the SharePoint site (to keep the look and feel similar) and link out of SharePoint. :-(
