Debugger2 Interface 

The Debugger2 object is used to interrogate and manipulate the state of the debugger and the program being debugged. The Debugger2 object supersedes the Debugger object.

Namespace: EnvDTE80
Assembly: EnvDTE80 (in envdte80.dll)

Public Interface Debugger2
	Inherits Debugger
Visual Basic (Usage)
Dim instance As Debugger2

public interface Debugger2 : Debugger

public interface class Debugger2 : Debugger
J#
/** @attribute GuidAttribute("8B5E2BFD-4642-4EFE-8AF4-0B2DA9AAA23C") */ 
public interface Debugger2 extends Debugger

Remarks

The debugger is available through the DTE2 object via its Debugger property, as shown in the example below. One debugger object is available for each instance of the development environment.

Example
Visual Basic
Imports EnvDTE
Imports System.Diagnostics

Public Module Module1
    'This function returns true if the debugger is actively debugging.

    Function IsDebugging() As Boolean
        Dim debugger As EnvDTE80.Debugger2debugger = DTE2.Debugger

        If (debugger Is Nothing) Then
            MsgBox("Debugger doesn't exist! Fatal error.")
            IsDebugging = false
        Else
            IsDebugging = (debugger.CurrentMode <> _
            dbgDebugMode.dbgDesignMode)
        End If
    End Function
End Module
C++
// The following C++ program can be run from the command line.
// It detects whether an instance of Visual Studio is currently 
// running,and if so, prints a message stating whether its debugger
// is actively debugging.
