Debugger3 Interface

Статья

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)

The Debugger3 type exposes the following members.

Properties

	Name	Description
	AllBreakpointsLastHit	(Inherited from Debugger2.)
	AllBreakpointsLastHit	Gets a collection of bound breakpoints that were last simultaneously hit.
	BreakpointLastHit	(Inherited from Debugger2.)
	BreakpointLastHit	Gets the last breakpoint hit.
	Breakpoints	(Inherited from Debugger2.)
	Breakpoints	Gets a collection of breakpoints.
	CurrentMode	(Inherited from Debugger2.)
	CurrentMode	Gets the current mode of the debugger within the context of the IDE.
	CurrentProcess	(Inherited from Debugger2.)
	CurrentProcess	Gets or sets the active process.
	CurrentProgram	(Inherited from Debugger2.)
	CurrentProgram	Sets or returns the active program.
	CurrentStackFrame	(Inherited from Debugger2.)
	CurrentStackFrame	Gets or sets the current stack frame.
	CurrentThread	(Inherited from Debugger2.)
	CurrentThread	Gets or sets the current thread being debugged.
	DebuggedProcesses	(Inherited from Debugger2.)
	DebuggedProcesses	Gets the list of processes that are being debugged.
	DTE	(Inherited from Debugger2.)
	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	(Inherited from Debugger2.)
	HexDisplayMode	Gets or sets a value that indicates whether the expressions are output in hexadecimal or decimal format.
	HexInputMode	(Inherited from Debugger2.)
	HexInputMode	Gets or sets a value that indicates whether the expressions are evaluated in hexadecimal or decimal format.
	Languages	(Inherited from Debugger2.)
	Languages	Gets a list of languages that the debugger supports.
	LastBreakReason	(Inherited from Debugger2.)
	LastBreakReason	Gets the last reason that a program was broken. If the program is running it returns DBG_REASON_NONE.
	LocalProcesses	(Inherited from Debugger2.)
	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 Symbol Locations and Loading Behavior.
	Parent	(Inherited from Debugger2.)
	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 Server.
	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 Symbol Locations and Loading Behavior.
	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	(Inherited from Debugger2.)
	Transports	Gets a collection of supported debugging transports.

Methods

	Name	Description
	Break(Boolean)	(Inherited from Debugger2.)
	Break(Boolean)	Causes the given process to pause its execution so that its current state can be analyzed.
	DetachAll()	(Inherited from Debugger2.)
	DetachAll()	Detaches from all attached programs.
	ExecuteStatement(String, Int32, Boolean)	(Inherited from Debugger2.)
	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)	(Inherited from Debugger2.)
	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)	(Inherited from Debugger2.)
	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 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)	(Inherited from Debugger2.)
	GetProcesses(Transport, String)
	Go(Boolean)	(Inherited from Debugger2.)
	Go(Boolean)	Starts executing the program from the current statement.
	RunToCursor(Boolean)	(Inherited from Debugger2.)
	RunToCursor(Boolean)	Executes the program to the current position of the source file cursor.
	SetNextStatement()	(Inherited from Debugger2.)
	SetNextStatement()	Sets the next instruction to be executed, according to the cursor position in the current source file.
	SetSymbolSettings	Sets various settings for the .PDB symbols used by Visual Studio for debugging and forces reloading of all symbols.
	StepInto(Boolean)	(Inherited from Debugger2.)
	StepInto(Boolean)	Steps into the next function call, if possible.
	StepOut(Boolean)	(Inherited from Debugger2.)
	StepOut(Boolean)	Steps out of the current function.
	StepOver(Boolean)	(Inherited from Debugger2.)
	StepOver(Boolean)	Steps over the next function call.
	Stop(Boolean)	(Inherited from Debugger2.)
	Stop(Boolean)	Stops debugging and terminates or detaches from all attached processes.
	TerminateAll()	(Inherited from Debugger2.)
	TerminateAll()	Terminates all currently running debugging processes.
	WriteMinidump(String, dbgMinidumpOption)	(Inherited from Debugger2.)
	WriteMinidump(String, dbgMinidumpOption)

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).
