Re: EnvDTE.CodeElement.get_EndPoint throws Argument exception

Hi Carlos,

Thanks for finding the time to respond. Nice to hear from you.

The released version of the addin VSNETcodePrint allows the user to format
the source code before printing it so that the connecting lines for the
language constructs are drawn correctly. (You can see the output samples on
my website www.starprint2000.com).

For this reason, the addin starts an Undo, format and prints the source code
and then aborts the Undo to ensure that the source code is left in its
origional state.

The error occurs if user sets option 'Leave open braces on the same line a
constrcut' from the Options -> Text Editor -> C# -> Formatting tab in the IDE
AND
The Undo context is started
AND
The source code is formatted

If you remove smart formatting then the problem does not occur. But I do
need to format the source code as I have stated in my opening paragraph above.
