Properties

	Name	Description
	CurrentId	The CurrentId property returns the pseudo-token for the thread id or process id, in a call to NameProfile, StartProfile, StopProfile, SuspendProfile, and ResumeProfile. Use this property to cause the method to operate on the current thread or process, rather than a specifically indicated one.

Methods

	Name	Description
	CommentMarkAtProfile(Int64, Int32, String)	The CommentMarkAtProfile method inserts a timestamp value, a numeric mark and a comment string in the .vsp file. The timestamp value can be used to synchronize external events. Profiling for the thread containing the CommentMarkAtProfile function must be ON for the mark and comment to be inserted.
	CommentMarkProfile(Int32, String)	The CommentMarkProfile method inserts a numeric marker and a text string in the .vsp file. Profiling for the thread containing the CommentMarkProfile function must be ON for the mark and comment to be inserted.
	Equals(Object)	(Inherited from Object.)
	GetHashCode()	(Inherited from Object.)
	GetType()	(Inherited from Object.)
	MarkProfile(Int32)	The MarkProfile method inserts a profile mark in the .vsp file. Profiling for the thread containing the MarkProfile function must be ON for the mark to be inserted.
	NameProfile(String, ProfileLevel, UInt32)	The NameProfile method assigns a string to the specified process or thread.
	ResumeProfile(ProfileLevel, UInt32)	The ResumeProfile method decrements the Suspend/Resume counter for the specified profiling level.
	StartProfile(ProfileLevel, UInt32)	The StartProfile method sets the counter to 1 (on) for the specified profiling level.
	StopProfile(ProfileLevel, UInt32)	The StopProfile method sets the counter to 0 (off) for the specified profiling level.
	SuspendProfile(ProfileLevel, UInt32)	The SuspendProfile method increments the Suspend/Resume counter for the specified profiling level.
	ToString()	(Inherited from Object.)
