public ref class InternalBufferOverflowException : SystemException

Constructors

	Name	Description
	InternalBufferOverflowException()	Initializes a new default instance of the InternalBufferOverflowException class.
	InternalBufferOverflowException(SerializationInfo^, StreamingContext)	This API supports the product infrastructure and is not intended to be used directly from your code. Initializes a new, empty instance of the InternalBufferOverflowException class that is serializable using the specified SerializationInfo and StreamingContext objects.
	InternalBufferOverflowException(String^)	Initializes a new instance of the InternalBufferOverflowException class with the error message to be displayed specified.
	InternalBufferOverflowException(String^, Exception^)	Initializes a new instance of the InternalBufferOverflowException class with the message to be displayed and the generated inner exception specified.

Properties

	Name	Description
	Data	Gets a collection of key/value pairs that provide additional user-defined information about the exception.(Inherited from Exception.)
	HelpLink	Gets or sets a link to the help file associated with this exception.(Inherited from Exception.)
	HResult	Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception.(Inherited from Exception.)
	InnerException	Gets the Exception instance that caused the current exception.(Inherited from Exception.)
	Message	Gets a message that describes the current exception.(Inherited from Exception.)
	Source	Gets or sets the name of the application or the object that causes the error.(Inherited from Exception.)
	StackTrace	Gets a string representation of the immediate frames on the call stack.(Inherited from Exception.)
	TargetSite	Gets the method that throws the current exception.(Inherited from Exception.)

Methods

	Name	Description
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetBaseException()	When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions.(Inherited from Exception.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetObjectData(SerializationInfo^, StreamingContext)	When overridden in a derived class, sets the SerializationInfo with information about the exception.(Inherited from Exception.)
	GetType()	Gets the runtime type of the current instance.(Inherited from Exception.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Creates and returns a string representation of the current exception.(Inherited from Exception.)

Events

	Name	Description
	SerializeObjectState	Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception.(Inherited from Exception.)

In a FileSystemWatcher, when you are notified of file changes, the system stores those changes in a buffer the component creates and passes to the Application Programming Interfaces (APIs). If there are many changes in a short time, the buffer can easily overflow, resulting in an exception being thrown, which essentially loses all changes. To keep the buffer from overflowing, use the FileSystemWatcher::NotifyFilter and FileSystemWatcher::IncludeSubdirectories properties to filter out your unwanted change notifications. You can also increase the size of the internal buffer through the FileSystemWatcher::InternalBufferSize property. However, increasing the size of the buffer is expensive, so keep the buffer as small as possible.

Examples

The following example shows how to create a FileSystemWatcher to monitor file changes (creates, deletes, renames, changes) occurring on a disk drive. The example also shows how to properly receive error notifications.
