How would I make a button that when clicked the user of the app will be posting a screenshot of the canvas page they are on and have it posted to their wall? And maybe add some comments with it as well.
you would have to require the user to add some additional plugin to their browser. There are many plugins that do this - for example clipboard.com provides this functionality.
To the best of my knowledge, these extensions actually make a request themselves (in the back-end) to the url you are currently on and takes the screenshot from that url on the actual server. From there it can be shared and commented on.
However with out some external utility I don't think this functionality is possible.
hope this helps...

I try to realize an application which is include a creation of screenshot using Foreground MediaProjection Button OUTSIDE of any activity.
Unfortunatelly, information provided in official page of MediaProjection APi https://developer.android.com/guide/topics/large-screens/media-projection is not enough for understanding what exactly I should to do.
Please, provide some guide with sample code on this topic or reference link.
I m trying to setup a few image categorization tasks on Mechanical Turk sandbox developer version. When I try to view the HIT(the annotation image), it appears blank. I clicked on the 'Accept HIT' button but I still couldn't see anything.
In order to make sure that nothing was wrong with my project setup in particular, I signed in as a worker to accept HITS on other projects involving image categorization. I still continue to see a blank image in their categorization projects, where the image to be annotated is supposed to be displayed.
Can anyone help with this problem?Thanks.
Problem solved - it was a simple browser incompatibility problem.
I know you have already answered this for yourself, however for other requesters out there I think this may be useful.
I was developing HITs and I too was having issues view the HIT in Sandbox in Chrome and Firefox, I realized that it had something to do with the script being blocked by the browser and the way to fix this was to "unblock the content" - usually a shield icon in the URL bar.
When further developing my HIT I added information about how to see the HIT in the description box of the HIT so turkers could read the instructions and then work on the HIT - to be absolutely clear to the turkers, I added a "(READ DESCRIPTION)" in the title so turkers would know where to look.
Hope this helps!
A little background info is that my team and I developed a website for a Real Estate Agency and I've been assigned the task of setting the image of the currently selected property into facebook's sharing feature.
The webpage for the property is dynamic as there are several listings, so what I've done is select the first image that is loaded on the page and set it to the og:image meta tag.
Now let's say I copy the URL and post it on Facebook, it'll show the correct thumbnail, HOWEVER, it'll also show multiple thumbnails from other listings.
All images on the website are over 200 x 200px and are within an aspect ratio of 3:1.
My question is, how do I tell Facebook to only take my initial image and not grab others while it's as it.
Is there perhaps a SelectSingleImage property that I can apply?
I've already spent more time searching for the answer to this issue than I would have liked, so thanks for any help provided, it's much appreciated.
One method I use sometimes is to recognize Facebook's server and simply provide it with different data. This way you can actually only have one image on the page (as far as Facebook knows).
I don't know anything about vb.net, but here is a simple code sample in PHP. All it does is perform a regular expression on the user agent of the request to match it against the string "facebook".
$isFacebook = false;
if(preg_match("/facebook/",strtolower($_SERVER["HTTP_USER_AGENT"]))) {
$isFacebook = true;
}
Facebook may very well change their user agent signature one day, but for now, I'm pretty sure you'll be safe but keep synced with the Developers Blog and the Roadmap.
It seems that Facebook saved those images in cache for some bizarre reason, but to resolve this issue all I had to do was enter the URL into Facebook's Linter tool which in turn cleared the cache on their server.
I was using an iframe share button solution to be able to share products or posts on facebook. I used this systeme wich worked great on about 10 different websites but this week, they all ended up no working.
I read I should get an appId for each website and use Asynchroneous SDK, which I did, and followed steps to get it to work:
Load the SDK with appId authentification.
Load jQuery if needed (some buttons require it).
Add button code were desired.
I can see the SDK is loaded in <div id="fb-root"></div> but the share button never appears on the page and it is not a layout issue. I have tried several different buttons but they all seam to never make it to the user.
I read a lot of posts about the issue but each one was magically solved on Jully 22nd... not mine. I need help implementing this first button as I need to fix many websites afterwards. Thx!
When doing a fresh implementation of FB btns I ended up going here:
https://developers.facebook.com/tools/debug
to force FB to crowl the pages I was working on at the moment.
This proved usedful in getting immediate feedback on how things were working out.
I need to create a screenshot of the page by providing a page URL to the command line tool. I found the following application: Convert HTML To Image. This tool is OK but want a more flexible application. I need to have ability to perform the following:
Go to the following page.
Click button.
Take a screenshot and save it.
I want to create an application that will test a site by going by URL, take a shots, and then send the images to the email.
Does anybody has an experience in solving such problems?
Watin can capture screenshots:
ie.CaptureWebPageToFile("c:\tmp\watin main page.jpg");

I am a contributor to the WatiN project and the author of the WatiN Test Recorder. To do what you want, I'd suggest using something like csExWB2 (http://code.google.com/p/csexwb2/). The demo will give you the basic browser, and you can add screen shots where you like. Emailing is not covered, but that should be fairly easy.
I know this is very old post but i want to leave a message for visitor of this post.
PhantomJS is one option (http://www.phantomjs.org).
According to the WatiN features page:
Supports creating screenshots of webpages
I would direct you to more specifical documentation, but the documentation web doesn't work well with Firefox, so I can't search it.
