Nested Types in VSTA v 2 Part III: Entry Point Classes

The sample in this post shows how to support nested types and implicitly declared events in entry point classes (note that the nested type is in the entry point class, but is not an entry point). For types nested in an entry point class, the workaround...

Nested Types in VSTA v 2 Part II: Implicitly Declared Events in VB in Non-Entry Point Classes

In Visual Basic, events can be declared explicitly or implicitly typed. When events are declared implicitly typed, Visual Basic creates a hidden type nested in the declaring type’s class. ProxyGen v 2 does not support nested types; however, the work around...

Nested Types in VSTA v 2 Part I: Types Nested in Non-Entry Point Classes

ProxyGen does not support nested types; however, with a little manual editing of the descriptor and proxy files nested types can be supported in the Proxy. There are three kinds of nested types that will be covered in this blog series (non-entry point...

Events in VSTA Part IV: Unloading Add-ins that do not Unhook from Events

As mentioned in Part III, any events an add-in hooks into should be unhooked in the add-in, presumably in the Shutdown method. Unfortunately, if the add-in does not unhook from an event this can cause problems- namely that the host application will continue...

Events in VSTA Part III: Hooking and Unhooking to Events in Add-ins

Events exposed through VSTA can be easily hooked into by add-ins. Like Visual Studio, VSTA automates hooking into events in both C# and Visual Basic. Unfortunately unhooking the events is not automated, but should be done explicitly prior to the add-in...

Events in VSTA Part II: Declaring Custom Events and EventArgs to Expose

To declare custom events to expose to VSTA, you will need to: 1) Create a delegate outside of any class (VSTA does not support nested types). 2) Explicitly declare the event as the delegate type from above (for more information on declaring events in...

Events in VSTA Part I: Declaring Non-Custom Events to Expose

To declare non-custom events to expose to VSTA is fairly straight forward in C#. For Visual Basic, the events must be declared explicitly. This is because VB hides implementation for implicitly declared events and creates a hidden nested event handler class....
