Methods

ExecuteOperation(IExecuteOperationEvent)

Called to execute an operation.

Declaration
public virtual void ExecuteOperation(IExecuteOperationEvent vsEvent)
Parameters
Type Name Description
IExecuteOperationEvent vsEvent

The event instance.
Remarks

Called to execute an operation. Upon returning from this method, VHI will wait until one of the model-defined destination entities is recognized. If none are recognized within the operation's model defined timeout, the operation fails.
During the course of the event, VHI will not process data from the host while the event handler is executing. The host data will only be processed during callbacks to VHI. Thus, at the points where the event handler needs to wait for the host to respond, the event handler should use the appropriate wait callbacks on the IScriptHostSession interface.

Exceptions
Type Condition
ApptrieveException

If an exception is thrown from this method the operation will fail.

InitializeLifetimeService()

Tell the .NET Framework remoting system that instances of this type have an infinite lifetime.
