Troubleshooting

As you develop your application, sooner or later you may lose
synchronization with the ODA. This is indicated by errors that talk about
the "http connection" or "Automation error." If you get this type of error,
the best thing to do is save and exit Visual Studio, then reopen the project.
Visual Studio usually puts your projects in the Documents list on the Start
menu, making it easy to open the project. When you rerun the project, your
computer will resynchronize with the ODA, and usually the problem goes
away at that point. If the problem is severe, the ODA will post a message
and undergo a clean-up for a lost connection, this will take approximately
one minute.
If you are getting this problem frequently, make sure that you always
execute a disconnect() for every connect(), even when debugging.
Executing a TerminateSession() just before your application exits will
help keep the ODA synchronized.
If Automation errors persist, go into Project > References and clear the
ODA objects, and then close the dialog. Reopen the dialog and reselect the
references. Refer to "Example 1: Simple Application for Controlling the
ODA" on page 154 for a step-by-step procedure of adding references.
