InfoPath - missing data connection files

/

 

Sometimes, your InfoPath doesn't show you all the data connection files available in your SharePoint data connections library:

In this screenshot, it is only showing 3. 
There is no way to navigate to see more.

 

Fix. 

Change the Item Limit in the default view for the Data Connection library in SharePoint.

Change that number.  The default is usually 30.  I had previously changed it down to 3 to take the earlier screenshot.  Let's bump it back to 300.

 

Now you can see all the data connections again.

Fixing Facebook preview picture of your SharePoint site

/

 

I have a lot of friends in the SharePoint community, and I see a lot of SharePoint related links shared in my social circles.  Sometimes, these links are hosted on a SharePoint site.  Universally, you know they are hosted on SharePoint because Facebook has picked a really bad picture as preview for the site.

Freebie referral: rules.ssw.com.au - SSW's Rules are some of the best I've seen documented in one place.  Check them out.  The site is beautiful.  It's just unfortunate that Facebook picks a really horrible picture asset for the preview.

Setting up the Preview Picture

Facebook publishes how to talk to its crawlers.  The specification that talks about the Open Graph API is Open Graph - Using Objects.

To specify a preview picture is actually very simple.

<meta property="og:image" content="/storage/JohnLiu.jpg" />

 

You can also use the pre-Open Graph syntax, if you don't provide og:image, Facebook can infer it from rel="image_src"

<link rel="image_src" href="/storage/JohnLiu.jpg" />

You need to have this inside your <head> tag.  Add this to your Master Page.  Easy!

 

Debugging

Facebook actually has a pretty nice debugging tool that will tell you how the scrapper is visiting your site.  And this can be very valuable to get insight into why the picture you've chosen isn't appearing.

Here, it's showing me the problem.  My picture is too small.

Fixed.

 

Now Facebook will pick the right picture all the time!

SharePoint Saturday Canberra 2013

SharePoint Saturday Melbourne 2013

/

It's that time again!  I'm down in Melbourne for SharePoint Saturday later today on July 27. 

I'm presenting TypeScript and SharePoint, with updated notes as I have been working with TypeScript since Feburary.  It's been just awesome.

The SharePoint Saturday version of the presentation will be more developer focused, and I'm hoping my audience will come with their dev hat on and ready to play with JavaScript and TypeScript.

I'll update this post later to include the download files for the presentation.

See you at SharePoint Saturday.  Early night and early morning for me later.

 

Update

 

Again, I had a lot of fun in Melbourne, had a lot of fun discussions and talked to a number of you guys about TypeScript in the real world.  Drop me a line as you start to play with TypeScript in your own environment.

Happy Birthday shout out to Elaine van Bergen!

Australian SharePoint Conference 2013 Melbourne

/

Thank you attendees for yet another super conference.  It was quite a lot of fun presenting TypeScript for SharePoint.

 

I've got lots of feedback regarding the section on JavaScript - and have heard you guys loud and clear:

  • While the examples are fun...
  • But if you have other stuff to talk about, skip it!

I will miss talking about hoisting.  One of the craziest JavaScript gotchas there ever was.
