Starting to use API from C# and getting exception

[Owl Saver]

Can someone help point me in the right direction to solve this problem? I have just started creating a C# program to access EA models. When I try to open the model and EA is running, I get an exception. If EA is not runing, it works. First I get a pop up that says "Failed to Create Empty Document". Then I get the following exception:

"The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT))"

The code I am using is:

bool RetVal = false;
m_Repository = new EA.RepositoryClass();

if (m_Repository == null)
{
      log.Fatal("EA API could not be started.");
      RetVal = false;
}
else
{
      if (m_Repository.OpenFile(base.FilePath))
      {
            RetVal = false;
            log.Fatal("Could not open " + base.FilePath + " in Read/Write mode.");
      }
      else
      {
            RetVal = true;
            log.Debug("Opened file = " + base.FilePath);
            log.Debug("================================================================================");
      }
}

Mmm... Are you using the C# start template provided by Sparx guys?

Michael,

That error you are getting has nothing to do with the C# program you are creating. I sometimes get that error too when I try to start a second (or third) instance of EA from within Windows.

A reboot usually helps for a while, after which the problem re-occurs. I don't really know what causing it.

If you haven't already, you might try opening up Task Manager and killing any EA processes that are hanging around in the background.  I've had this happen especially when testing; the instances don't always shut down cleanly and after a while no new ones are created.
