Debugger Interface

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

Namespace:  EnvDTE
Assembly:  EnvDTE (in EnvDTE.dll)

Syntax

'Declaration
<GuidAttribute("338FB9A0-BAE5-11D2-8AD1-00C04F79E479")> _
Public Interface Debugger
'Usage
Dim instance As Debugger
[GuidAttribute("338FB9A0-BAE5-11D2-8AD1-00C04F79E479")]
public interface Debugger
[GuidAttribute(L"338FB9A0-BAE5-11D2-8AD1-00C04F79E479")]
public interface class Debugger
public interface Debugger

Remarks

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

Examples

The following example demonstrates how to use Debugger object.

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 EnvDTE.Debugger
        debugger = DTE.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
// The following small 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.

#include <stdio.h>
#import "dte.olb" raw_interfaces_only named_guids

using namespace EnvDTE;

int main(void)
{
    int nRet = 0;

    CoInitialize(NULL);

    IUnknownPtr pUnk;
    GetActiveObject(CLSID_DTE, NULL, &pUnk);

    if (pUnk == NULL) {
        printf ("No instance of Visual Studio is running.\n");
    }
    else {
        _DTEPtr pDTE = pUnk;
        if (pDTE) {
            DebuggerPtr pDebugger;
            if (SUCCEEDED(pDTE->get_Debugger(&pDebugger)) && pDebugger != NULL){
                dbgDebugMode mode;
                if (SUCCEEDED(pDebugger->get_CurrentMode(&mode))) {
                    if (mode != dbgDesignMode) {
                        printf("Debugger is active.\n");
                        nRet = 1;
                    }
                    else {
                        printf("Debugger is not active.\n");
                    }
                }
            }
        }
    }

    CoUninitialize();

    return nRet;
}
