This interface represents a source document.
Syntax
IDebugDocument2 : IUnknown
Notes for Implementers
Visual Studio typically implements this interface. A debug engine (DE) can also implement this interface when it needs to supply the source code and the source does not exist on disk. In such cases, the DE would also implement IDebugDocumentContext2 and IDebugActivateDocumentEvent2 interfaces, as well as some additional methods on the IDebugDisassemblyStream2 and IDebugDocumentPosition2 interfaces.
Notes for Callers
Methods on the IDebugDocumentContext2, IDebugDisassemblyStream2, IDebugDocumentPosition2, and IDebugActivateDocumentEvent2 interfaces return this interface.
Methods in Vtable Order
The following table shows the methods of IDebugDocument2.
| Method | Description |
|---|---|
| GetName | Gets the name of the document in one of several forms. |
| GetDocumentClassID | Gets the class identifier of the document. |
Remarks
This interface is implemented only when the DE supplies the source code. For example, when you are debugging script on an HTML page, the DE supplies the source code because the source is downloaded or generated dynamically and does not exist as a disk file. When debugging traditional languages, such as C++, this interface does not need to be implemented.
