DispatcherOperationCallback Delegate

 

Represents a delegate to use for dispatcher operations.

Namespace:   System.Windows.Threading
Assembly:  WindowsBase (in WindowsBase.dll)

public delegate Object^ DispatcherOperationCallback(
	Object^ arg
)

Parameters

arg
Type: System::Object^

An argument passed to the callback.

Return Value

Type: System::Object^

The object returned by the callback.

It is not necessary to use this delegate for dispatcher operations, but DispatcherOperationCallback and SendOrPostCallback use dynamic invoking.

Partial Trust applications do not support dynamic invoking, so you must use either DispatcherOperationCallback or SendOrPostCallback if the application is going to be running in Partial Trust.
