This interface is sent by the debug engine (DE) to the session debug manager (SDM) to output a string.
Syntax
IDebugOutputStringEvent2 : IUnknown
Notes for Implementers
The DE implements this interface to send a string to the Output window of the IDE. The IDebugEvent2 interface must be implemented on the same object as this interface. The SDM uses QueryInterface to access the IDebugEvent2 interface.
Notes for Callers
The DE creates and sends this event object to send a string to the Output window. The event is sent by using the IDebugEventCallback2 callback function that is supplied by the SDM when it is attached to the program being debugged.
Methods in Vtable Order
The following table shows the method of IDebugOutputStringEvent2.
| Method | Description |
|---|---|
| GetString | Gets the displayable message. |
Remarks
For example, in unmanaged code, the string to be output can originate when the program being debugged sends a string to the Win32 OutputDebugString function. This string is intercepted by the DE and sent on to the SDM as the IDebugOutputStringEvent2 event.
Use IDebugMessageEvent2 to send a message that requires a user response.
Use IDebugErrorEvent2 to send an error message that does not require a response.
