Word appears to be getting confused

[David Thielen]

I see this error in the following code:
foreach (InlineShape item in
range.InlineShapes)
{
try
{
if ((item.Range.End <=
startSearch) || (endSearch <= item.Range.Start))
continue;

// chart (with tag)?
if (item.HasChart ==
MsoTriState.msoTrue)
{
// fast check
if
(string.IsNullOrEmpty(item.AlternativeText) ||

((!item.AlternativeText.StartsWith("<wr:")) &&
(!item.AlternativeText.StartsWith("</wr:"))))

continue;

string
xmlChart = item.Range.WordOpenXML;

On the call to WordOpenXML I get a COMException of:
- $exception {"The object is not valid."}
System.Exception {System.Runtime.InteropServices.COMException}

What's really screwy is in the debugger I can then do a Quickwatch on
"item.Range.WordOpenXML" and I get the string - no exception.

Then when I say continue I get:
System.AccessViolationException occurred
Message="Attempted to read or write protected memory. This is often
an indication that other memory is corrupt."
Source="Microsoft.Office.Interop.Word"
StackTrace:

AutoTag2010.net.windward.autotag.word.WordTagHandler.FindAllTags(Selection
selOn, Boolean justFirst, Int32 startSearch, Int32 endSearch) in
C:\src\version9\AutoTag\AutoTag2010\net\windward\autotag\word\WordTagHandler.cs:line
677
InnerException:

And Word is basically hosed - I need to exit it.

Any idea why?

thanks - dave

Found & fixed - the call to WordOpenXML was triggering the selection
change event (no idea why) which my handler then recursively called
back in to this code.

Calling WordOpenXML recursively is very very bad!!!
