I have a C# COM Add-in which inserts custom HTML into the body of the email.
Using OutlookSpy, I see the following events have fired:
PropertyChange (To)
PropertyChange (CC)
PropertyChange (BCC)
PropertyChange (To)
PropertyChange (CC)
PropertyChange (BCC)
PropertyChange (To)
PropertyChange (CC)
PropertyChange (BCC)
PropertyChange (ReceivedTime)
Write (false)
BeforeCheckNames (false)
AfterWrite ()
<Unknown(DispID=0x0000FC95)> (false)
PropertyChange (ConversationTopic)
PropertyChange (ConversationIndex)
PropertyChange (Subject)
PropertyChange (InternetCodepage)
PropertyChange (HTMLBody)
CustomPropertyChange (--- custom data ---)
CustomPropertyChange (--- custom data ---)
CustomPropertyChange (--- custom data ---)
CustomPropertyChange (--- custom data ---)
The code is working fine. I'm wondering what event corresponds to the DISPID 0x0000FC95. I might be able to use it for something in the future.
It is a cancelable version of the AfterWrite event. It is not supported or documented by Microsoft. They introduced it in the OOM, but it never made into the type library. They can take it away at any moment, you are better off not using it.

According to the XForms specification most events are said to "bubble".
As per the DOM Level 2 Event Specification an event that "bubbles" means that the handlers for this event associated with ancestor elements of the event dispatch target will also receive this event.
For an event to be specified as "bubbles" it means the xf:dispatch action cannot modify the bubble behavior to limit it to the target.
I don't understand what the benefit is of so many xforms events to bubble. For example, xforms-select and xforms-deselect. They apply to xf:item (of xf:select*) and xf:case (of xf:switch, i.e., used in a form with tabs).
Let's say I have an xf:case with an xforms-select handler that will cause a refresh on an expensive rendering widget, just when the tab is actually selected rather than every time the model is updated. Now I also have an xf:select in that same tab. Now whenever the user selects another item in that selection, the xf:case would receive the xforms-select at the bubble phase, doing the costly update operation every time.
This doesn't seem to make sense.
In fact xforms-node-attached has it right: we really want to be specific as to which form element gets the node attached. But apart from that, most events are said to bubble.
I could conform myself better with this issue if I understood the reason for this. Otherwise I am tempted to change my XForms engine to change the definition of xforms-select and xforms-deselect not to bubble.
This is to allow what is known as event delegation:
"Event delegation refers to the process of using event propagation (bubbling) to handle events at a higher level in the DOM than the element on which the event originated. It allows us to attach a single event listener for elements that exist now or in the future." (from an older version of this jQuery doc page)
In general, this is a good thing:
You use less event listeners.
A listener can listen on multiple targets.
You don't need to remove/add listeners as DOM elements are added/removed.
It seems that, in the HTML world, things have moved towards letting everything bubble. For example, the old focus event didn't bubble, and the newer focusin event bubbles.
If you have an event handler which gets activated by events dispatched to multiple targets, in some cases you need the ability to discriminate. This is where event context information is useful. Libraries like jQuery also allow you to associate an event handler filtered by CSS selector, which is neat.
Now in the case of xforms-select specifically, your issue is that you cannot discriminate between this event dispatched to an xf:case vs. an xf:select. This might mean XForms shouldn't have a single event for these two scenarios, or it should have enough event context information to discriminate between the two. I don't think that this is making a case for not letting the event bubble.
I have two custom controls tDescendant1 and tDescendant2 that are descendants of other custom control tAncestor. tAncestor handle some events as MouseDown, Click, etc. tDescendant1 and tDescendant2 also must handle the Click event, so they, in turn, set the ancestor's OnClick event to its own handler.
I have on the form Descendant1 and Descendant2 (wich are instances of tDescendant1 and tDescendant2 respectively) and I need that when an OnClick event is fired on Descendant1, the underlying tAncestor of Descendant2 be notified.
Can I use observers to accomplish this?
Appreciate any suggestion. Thanks.
In CRM 2011, i wrote a function in js and attached that function to OnChange event of a field. When the value changed in LookUpField1, it should update value of another LookUpField2 but it is only updating after saving and loading the form.
Where as if i use addonChange and firing the function, LookUpField2 value is automatically updating when LookUpField1 is changed.
Why is it working with addonChange and not OnChange event of attr?
Apart from programmatically firing a function using addonChange, are there any instances where we need to use addonchange?
I hope i make sense ;) & Thanks in advance!!!
OnChange is the event. addOnChange is the way to add a handler Here's what the documentation says:
OnChange Event
Use the addOnChange, removeOnChange, and fireOnChange
methods and to manage event handlers for the OnChange event.

As I wrote I'd like to write a custom event foa a Raphael's element, how can i do?
I just saw that eve(name, scope, varargs) but I didn't understand well, and if properly for creating a custom event.
I'd like understand how to create a my own custom event.
I have read all the official documentation of jQuery 1.7.2, but I cannot find any detail about the 'beforechange' event (or something like that) which help me control some rules before allowing the element to change its value. Is there any plugins provide this handler?
Thank you so much!
The jQuery api doesnot provide the 'beforechange' event but instead provide great flexibility to write our own custom events. We can define our own custom events and can be triggered when the events is fired.
For example for input elements we can have onkeydown or onkeypress events and when fired we can trigger our custom events to control some rules.
The following link provides information for creating custom events. Its very simple and flexible.
