I know "MediaLinkPrefix" can be changed in web.config. But is it possible to change "MediaLinkPrefix" Programmatically? Thanks!
To answer your specific question. No. You cannot programmatically change the value of that setting.
If you are trying to use Sitecore.Resources.Media.MediaManager.GetMediaUrl(mediaItem) to get the URL of a MediaItem then that is leveraging the Sitecore.Resources.Media.MediaProvider, which pulls the value of the MediaLinkPrefixfrom the Sitecore.Resources.Media.MediaConfig class. That property does not have a 'setter'. Furthermore, the value of that property actually comes from Sitecore.Configuration.Settings.Media.MediaLinkPrefix, which also doesn't have a setter and is pulled directly from the config file.
The MediaManager is a static class that I believe isn't able to be swapped out with a custom implementation. And, unlike the LinkManager, the MediaManager is hard coded to use the Sitecore.Resources.Media.MediaProvider so you can't write a custom provider either.
You can do this by creating your own implementation of Sitecore.Links.LinkProvider and set it up in your web.config under the <linkManager> section.
I don't know the exact implementation, but you can inherit a class from Sitecore.Links.LinkProvider and then override the GetItemUrl() method.
Then configure your class to be used as LinkManager.

Let's say we have a model like this:
class UserConfig(ndb.Model):
name = ndb.StringProperty()
email_subscriber = ndb.BooleanProperty(default=True)
Let's assume email_subscriber was set to default True by mistake and we want to fix that mistake and use default=False instead. I tried changing the value to default=False and that works fine for users created after that code is deployed, but that doesn't fix the problem for existing users.
Is there a way (e.g. some internal property which isn't documented in Datastore documentation), which would provide info whether given prop value was set explicitly by user or using the provided default.
I can write an upgrade which would set email_subscriber=False for all users, but I'm afraid some users might have intentionally checked this property in the app and wouldn't like to break their experience.
tl;dr: How can I determine if value in ndb object was set using the default for that property or was provided explicitly.
There is no way to know this. Once a value is set in the database there is no way to know which part of your code (ndb runs in your code from the database perspective) set the value.
I am using APEX 20.2.0.00.20. apex.region(region_static_id).widget() method should return a jQuery object according to the documentation. I am trying to figure out how to know what the object's properties and methods are, especially when they are not mentioned in the documentation. I tried running apex.region(calendar_region_static_id).widget() to return the object and inspect what properties and methods it has but I got S.fn.init [div#CAL_calendar.fc.ui-widget.fc-ltr, prevObject: S.fn.init(1)] 0: div#CAL_calendar.fc.ui-widget.fc-ltr length: 1 prevObject: S.fn.init [document] __proto__: Object(0)
I did not get the object. I do not know what s.fn.init or the rest of the returned code is?!
I see code like apex.region("calendar_static_id").widget().fullCalendar("getView"), so I assumed I should have gotten the jQuery object which has the "fullCalendar" method and more when I ran apex.region(calendar_region_static_id).widget(), but I have not.
Is this not the right way to inspect a jQuery object's properties and methods?
APEX integrates the FullCalendar widget, but it doesn't duplicate its documentation. Have a look here for a list of the FullCalendar methods and options.
In general, most (interactive) APEX regions are implemented as jQuery UI widgets. That means you can use them like this:
$('selector').widgetName('methodName'); //invokes said method
$('selector').widgetName('methodName', 'param1'); //invokes said method with a parameter
$('selector').widgetName('option', 'optionName'); //gets a specific option
$('selector').widgetName('option', 'optionName', 'newVal'); //sets a specific option
What's more, you can inspect all available options by running:
$('selector').widgetName('option');
And even have a look at the internal object, see all methods, public and otherwise, via:
$('selector').widgetName('instance');
Moreover, via its region interface, APEX offers an even easier way to reach those methods and options, even without having to know a region's widgetName:
// this
$('widgetSelector', 'staticId').widgetName('methodName');
// is equivalent to
apex.region('staticId').widget().widgetName('methodName');
// is quivalent to
apex.region('staticId').call('methodName');
The last way is the shortest and doesn't require knowing the real widget's id or widget name.
All of this helps when dealing with regular APEX widgets, such as the Interactive Grid.
apex.region('emp').call('instance'); //inspects all methods
apex.region('emp').call('option'); //inspects all options
This however does not work on the FullCalendar region, for reasons that are beyond me. It should help you navigate all other APEX regions, but for the FullCalendar you'll have to resort to their API docs.
Hope this helps a bit.
I'm using Sitecore. I want to get the full name/description of a DMS rule in programcode by Sitecore ID, for example: "Where the DayOfWeek has a value that is equal to Tuesday".
Who knows how to do this?
Thanks a lot.
Jordy
I don't know of a simple way, but the class responsible for rendering the rule text is Sitecore.Shell.Applications.Rules.RulesRenderer in Sitecore.Client.dll.
Its constructor accepts the XML from a rules field and you call the Render method, passing in a prepared HtmlTexteWriter. It also has a bunch of fairly self-explanatory private methods like RenderRule, RenderCondition etc.
I'm sure if you decompile that class you can pick out the bits you need.
I am currently in the process of writing a custom DataProvider. Using the Intergrate External Data documentation.
I've managed to show the external data in the Sitecore back end. However whenever I try to view the data in the items I created, I am getting an error
Null ids are not allowed. <br> Parameter name: displayName
There seems to be precious little on the subject on how to create a custom DataProvider on the Sitecore Developer Network.
The example on their website seems to only show how to import a SINGLE item into a static database. However I am simply trying to merge some items into the hierarchy and I can't find any useful documentation.
It seems that one of your methods that should return an ID doesn't. It might be GetChildIds and/or GetParentId.
Nick Wesselman wrote a good article about it gathering all the information including an example on the Marketplace. I think that is your best start. You can read it here.
Turns out I needed to include at the very least, the Fields->Section->Template in the GetParent method. To be on the safe side I included the Fields/Sections/Templates into my implementations of
GetChildIDs
GetItemDefinition
GetParentID
It wasn't obvious that this was the case, since I had in fact implemented the GetTemplates method correctly, and I had expected that should be enough.
Im currently using ie as an active x com thing on wxWidgets and was wanting to know if there is any easy way to change the user agent that will always work.
Atm im changing the header but this only works when i manually load the link (i.e. call setUrl)
The only way that will "always work," so far as I've been able to find, is changing the user-agent string in the registry. That will, of course, affect every web browser instance running on that machine.
You might also try a Google search on DISPID_AMBIENT_USERAGENT. From this Microsoft page:
MSHTML will also ask for a new user
agent via DISPID_AMBIENT_USERAGENT
when navigating to clicked hyperlinks.
This ambient property can be
overridden, but it is not used when
programmatically calling the Navigate
method; it will also not cause the
userAgent property of the DOM's
navigator object or clientInformation
behavior to be altered - this property
will always reflect Internet
Explorer's own UserAgent string.
I'm not familiar with the MSHTML component, so I'm not certain that's helpful.
I hope that at least gives you a place to start. :-)
I did a bit of googling today with the hint you provided head geek and i worked out how to do it.
wxWidgets uses an activex rapper class called FrameSite that handles the invoke requests. What i did was make a new class that inherits from this, handles the DISPID_AMBIENT_USERAGENT event and passes all others on. Thus now i can return a different user agent.
Thanks for the help.
Head Geek already told you where in the registy IE will look by default.
This is just a default, though. If you implement [IDocHostUIHandler::GetOptionKeyPath](http://msdn.microsoft.com/en-us/library/aa753258(VS.85%29.aspx) or [IDocHostUIHandler2::GetOverrideKeyPath](http://msdn.microsoft.com/en-us/library/aa753274(VS.85%29.aspx), IE will use that registry entry instead.
You'll probably want to use SysInternal's RegMon to debug this.
