This interface is used to notify Visual Studio about changes to the source document that are supplied by the debug engine.
Syntax
IDebugDocumentTextEvents2 : IUnknown
Notes for Implementers
The DE implements this interface to support making changes to the source code. This interface is typically implemented on the same object that implements the IDebugDocument2 interface.
Notes for Callers
Visual Studio obtains this interface through a call to the Advise method. The IConnectionPoint interface is obtained from a call to the EnumConnectionPoints method. The IConnectionPointContainer interface is obtained by calling the QueryInterface method on an IDebugDocument2 interface.

The following table shows the methods of IDebugDocumentTextEvents2.

Remarks

In the process of interpreting scripts, new source code can be generated that is not present in any disk file and is known only to the DE.
