Microsoft.Office.Interop.Word.ApplicationEvents3_Event.DocumentChange not always firing

[David Thielen]

Hi;

I have an event handler for DocumentChange and when I have 2 Word
documents (Word 2007) up, when I switch between the two documents,
this event only fires about half the time.

I HAVE to have an event when switching documents because things change
- like what items are enabled in the ribbon menu. How can I get this
to always work or is there another event that always fires when
switching documents?

It doesn't stop working, it's just intermittent, works twice doesn't
once, does once, doesn't 3 times, does twice... Pretty random.

thanks - dave

Hello Dave,

Thanks for using Microsoft Newsgroup Support Service!

To enable or disable items on ribbon according to which Word document is
presented to user, it is recommended to use the Application.WindowActivate
event as the following:

private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
this.Application.WindowActivate += new
Microsoft.Office.Interop.Word.ApplicationEvents4_WindowActivateEventHandler(
Application_WindowActivate);
}

void Application_WindowActivate(Microsoft.Office.Interop.Word.Document Doc,
Microsoft.Office.Interop.Word.Window Wn)
{
Globals.Ribbons.Ribbon1.button1.Enabled = false;
}

This event fires when any document window is activated. The following is
the related document in the MSDN:
http://msdn.microsoft.com/en-us/library/aa211901(office.11).aspx

Please let me know whether this works for your scenario.

Hello Dave,

I want to add some comments about the
Word.ApplicationEvents3_Event.DocumentChange event. I create two Shared
Add-In projects to perform the test. One of them targets PIA2003, and
another targets PIA 2007. Both work fine. The DocumentChange event fires
when a new document is created, an existing document is opened, or another
document is made the active document, as MSDN document describes.

As far as I know, the internal implementation of the DocumentChange event
relies on the WindowActivate event, thus I suggested you try the
WindowActivate event. If the WindowActivate event still does not work for
your scenario, could you please provide more information of the issue's
context? Like whether the Office 2007 SP1 is installed, and whether you
use the Office 2003 PIA, the Office XP PIA or the IA generated by yourself.
It will be helpful if you can provide detailed reproduce steps.

Hi;

Found it - our fault (sorry).

We have found that calling Word.Find() in the header/footer part of a
document causes DocumentChange to be called. In our DocumentChange
handler we call Find() to determine menu settings. Needless to say,
this locks up Word.

So we have a bunch of tests to make sure that DocumentChange() is not
being called for this reason. Only if we know it's safe do we then
call our internal DocChange() handler. It was tripping on one of those
tests.
