Syntax

'Declaration
Public MustOverride Property FreezeEvents() As Boolean

public abstract bool FreezeEvents {get; set;}

public: property virtual Boolean FreezeEvents{
    Boolean get();
    Void set(Boolean);
}

public abstract boolean get_FreezeEvents();

public abstract function get FreezeEvents() : Boolean;
public abstract function set FreezeEvents(Boolean);

Remarks

When set to TRUE, the application has requested that the service object not deliver events. Events will be queued by the service object but not delivered until the application changes FreezeEvents to FALSE. Exclusive-use devices must be opened and claimed before this property can be accessed. Shared devices must be opened before this property can be accessed.

When set to FALSE, the application allows events to be delivered. If some events have been held while events were frozen and all other conditions are correct for delivering the events, changing FreezeEvents to FALSE will allow these events to be delivered.

An application can choose to freeze events for a specific sequence of code where interruption by an event isn’t desirable.

FreezeEvents is initialized to FALSE. State verification takes place in the basic and base classes for each device.
