[V8i, VB.NET] OnDesignFileOpened using Bentley.Interop.MicroStationDGN.dll wrapper

In .NET you can use Addin's events - NewDesignFileEvent in your case.

      Bentley.MicroStation.AddIn addin = ...;
      addin.NewDesignFileEvent += ...;
      addin.ModelChangedEvent += ...;

Hi Lars,

I have no personal experience with this sitution, because I use C# if NET Framework is chosen platform for the application (and C# doesn't support WithEvent construction), but if you use VB.NET, the usage would be pretty the same as in MicroStation VBA.

So I guess you should try to combine example code from MicroStation VBA help file (Open, Close, and Idle Events Handler Example) and some example of VB.NET code (e.g. this one).

With regards,

One more note: The solution mentioned by Dušan is better, it's based on standard events implemented in API.

• If you are interested in the event when model is changed (which means design file can remain the same, but also can change), ModelChangedEvent is the way.
• If you are interested in the event when the design file is changed only (another design file is opened), NewDesignFile is the solution. This event provides also Name of the design file and the information When the event was fired. It important, because the event is fired twice - at first before the current file is closed and consequently for the second time when the new one is opened.

With regards,

Thank's

I will try to use the Addin's events
