Debugger3 Interface

Definition

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

Remarks

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).

Properties

AllBreakpointsLastHit

Gets a collection of bound breakpoints that were last simultaneously hit.

BreakpointLastHit

Gets the last breakpoint hit.

Breakpoints

Gets a collection of breakpoints.

CurrentMode

Gets the current mode of the debugger within the context of the IDE.

CurrentProcess

Gets or sets the active process.

CurrentProgram

Sets or returns the active program.

CurrentStackFrame

Gets or sets the current stack frame.

CurrentThread

Gets or sets the current thread being debugged.

DebuggedProcesses

Gets the list of processes that are being debugged.

DTE

Gets the top-level extensibility object.

ExceptionGroups

Gets 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.

ForceContinue

Gets 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.

HexDisplayMode

Gets or sets a value that indicates whether the expressions are output in hexadecimal or decimal format.

HexInputMode

Gets or sets a value that indicates whether the expressions are evaluated in hexadecimal or decimal format.

Languages

Gets a list of languages that the debugger supports.

LastBreakReason

Gets the last reason that a program was broken. If the program is running it returns DBG_REASON_NONE.

LocalProcesses

Gets the list of processes that currently running on this computer.

OnlyLoadSymbolsManually

Gets 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 How to: Specify a Symbol Path.

Parent

Gets the immediate parent object of the Debugger3 object (DTE2).

SymbolCachePath

Gets 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 How to: Use a Symbol.

SymbolPath

Gets 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 How to: Specify a Symbol Path.

SymbolPathState

Gets a string that represents the state of all symbol paths for the .PDB symbol files that are used by Visual Studio for debugging.

Transports

Gets a collection of supported debugging transports.

Methods

Break(Boolean)

Causes the given process to pause its execution so that its current state can be analyzed.

DetachAll()

Detaches from all attached programs.

ExecuteStatement(String, Int32, Boolean)

Executes 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.

GetExpression(String, Boolean, Int32)

Evaluates 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.

GetExpression2(String, Boolean, Boolean, Int32)

Evaluates 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(String, Boolean, Int32) but with an additional Boolean parameter, which can be set to true to indicate that the expression is to be evaluated as a statement.

GetProcesses(Transport, String)
Go(Boolean)

Starts executing the program from the current statement.

RunToCursor(Boolean)

Executes the program to the current position of the source file cursor.

SetNextStatement()

Sets the next instruction to be executed, according to the cursor position in the current source file.

SetSymbolSettings(String, String, String, Boolean, Boolean)

Sets various settings for the .PDB symbols used by Visual Studio for debugging and forces reloading of all symbols.

StepInto(Boolean)

Steps into the next function call, if possible.

StepOut(Boolean)

Steps out of the current function.

StepOver(Boolean)

Steps over the next function call.

Stop(Boolean)

Stops debugging and terminates or detaches from all attached processes.

TerminateAll()

Terminates all currently running debugging processes.

WriteMinidump(String, dbgMinidumpOption)

Applies to
