Debugger3 Interface

Debugger3 is used to interrogate and manipulate the state of the debugger and the program being debugged. Debugger3 supersedes the Debugger2 and Debugger interfaces.

Namespace:  EnvDTE90
Assembly:  EnvDTE90 (in EnvDTE90.dll)

[GuidAttribute("87DFC8DA-67B4-4954-BB89-6A277A50BAFC")]
public interface Debugger3 : Debugger2

The Debugger3 type exposes the following members.

  NameDescription
Public propertyAllBreakpointsLastHitGets a collection of bound breakpoints that were last simultaneously hit.
Public propertyBreakpointLastHitGets the last breakpoint hit.
Public propertyBreakpointsGets a collection of breakpoints.
Public propertyCurrentModeGets the current mode of the debugger within the context of the IDE.
Public propertyCurrentProcessGets or sets the active process.
Public propertyCurrentProgramSets or returns the active program.
Public propertyCurrentStackFrameGets or sets the current stack frame.
Public propertyCurrentThreadGets or sets the current thread being debugged.
Public propertyDebuggedProcessesGets the list of processes that are being debugged.
Public propertyDTEGets the top-level extensibility object.
Public propertyExceptionGroupsGets the exception settings for the debugger. For each exception, these settings determine whether the debugger gives the code an opportunity to handle the exception before the debugger breaks execution.
Public propertyForceContinueGets or sets a value that determines whether the debugger breaks or continues when a tracepoint or breakpoint finishes executing a macro. The default behavior is set by the user in the dialog box when the tracepoint or breakpoint is created. This property can be used to change the default behavior.
Public propertyHexDisplayModeGets or sets a value that indicates whether the expressions are output in hexadecimal or decimal format.
Public propertyHexInputModeGets or sets a value that indicates whether the expressions are evaluated in hexadecimal or decimal format.
Public propertyLanguagesGets a list of languages that the debugger supports.
Public propertyLastBreakReasonGets the last reason that a program was broken. If the program is running it returns DBG_REASON_NONE.
Public propertyLocalProcessesGets the list of processes that currently running on this computer.
Public propertyOnlyLoadSymbolsManuallyGets a value that determines whether symbols are loaded manually or automatically. The Visual Studio user can determine this setting in the Options dialog box. For more information about how to set this value within Visual Studio, see [OBSOLETE] How to: Specify Symbol Locations and Loading Behavior.
Public propertyParentGets the immediate parent object of the Debugger3 object (DTE2).
Public propertySymbolCachePathGets a string that contains the path to the symbols cache used by Visual Studio when you download symbols from a symbols server. You can specify the symbols cache path in the Options dialog box. For more information, see [OBSOLETE] How to: Use a Symbol Server.
Public propertySymbolPathGets a string that contains paths to .PDB symbol files that are used by Visual Studio for debugging. The Visual Studio user can specify symbols paths in the Options dialog box. For more information, see [OBSOLETE] How to: Specify Symbol Locations and Loading Behavior.
Public propertySymbolPathStateGets a string that represents the state of all symbol paths for the .PDB symbol files that are used by Visual Studio for debugging.
Public propertyTransportsGets a collection of supported debugging transports.

  NameDescription
Public methodBreakCauses the given process to pause its execution so that its current state can be analyzed.
Public methodDetachAllDetaches from all attached programs.
Public methodExecuteStatementExecutes the specified statement. If the TreatAsExpression flag is true, then the string is interpreted as an expression, and output is sent to the Command Window.
Public methodGetExpressionEvaluates an expression based on the current stack frame. If the expression can be parsed but not evaluated, an object is returned but does not contain a valid value.
Public methodGetExpression2Evaluates an expression based on the current stack frame. If the expression can be parsed but not evaluated, an object is returned but does not contain a valid value. This member function is similar to GetExpression but with an additional Boolean parameter, which can be set to true to indicate that the expression is to be evaluated as a statement.
Public methodGetProcesses
Public methodGoStarts executing the program from the current statement.
Public methodRunToCursorExecutes the program to the current position of the source file cursor.
Public methodSetNextStatementSets the next instruction to be executed, according to the cursor position in the current source file.
Public methodSetSymbolSettingsSets various settings for the .PDB symbols used by Visual Studio for debugging and forces reloading of all symbols.
Public methodStepIntoSteps into the next function call, if possible.
Public methodStepOutSteps out of the current function.
Public methodStepOverSteps over the next function call.
Public methodStopStops debugging and terminates or detaches from all attached processes.
Public methodTerminateAllTerminates all currently running debugging processes.
Public methodWriteMinidump

The debugger is available through the DTE2 object through its Debugger property, as shown in the following example. One debugger object is available for each instance of the interactive development environment (IDE).

// 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.

#include <stdio.h>
#import "dte90.olb" raw_interfaces_only named_guids
using namespace EnvDTE90;
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(&pDebugger3)) && 
            pDebugger3
            != NULL){
                dbgDebugMode mode;
                if (SUCCEEDED(pDebugger3->get_CurrentMode(&mode))) {
                    if (mode != dbgDesignMode) {
                        printf("Debugger is active.\n");
                        nRet = 1;
                    }
                    else {
                        printf("Debugger is not active.\n");
                    }
                }
            }
        }
    }
    CoUninitialize();
    return nRet;
