Hi all!

Could anyone please explain me, why if I try to load an external
component, the VSTO program fails.

For example, I wrote the line:
ADODB.Connection conn;
When debugging everything is ok, but after publishing the execution fails
at this line without any error, with no messages.
It's VS.NET 2005 and VSTO 2003.

Thanks in advance for any ideas,
A. Dzizenko.

have a look at your event log files to see if there are any COM exceptions
being thrown

Unfortunatelly there was no error. Everything looks like the program exits
correctly.

firstly, vs.net 2005 does not run vsto 2003 - the two are not compatible.

This doesn't ring true. I installed VS.NET 2005 and Tools for Office 2003
(maybe they're called 2005, but they're for Office 2003), and VSTO was a
part of VS (Team Edition). After that I can't beleive that VS.NET 2005
doesn't run VSTO 2003.

Hello Andrey,

it maybe concerns to a security setting.
Maybe you have to give your assembly more access.
Did you surrounded the statement that throws the exception with a try/catch
block ?
what is the ErrorMessage ?
