Syntax
'Declaration
Public Overridable Event BeforeExecute As _dispCommandEvents_BeforeExecuteEventHandler
public virtual event _dispCommandEvents_BeforeExecuteEventHandler BeforeExecute
public:
virtual event _dispCommandEvents_BeforeExecuteEventHandler^ BeforeExecute {
void add (_dispCommandEvents_BeforeExecuteEventHandler^ value);
void remove (_dispCommandEvents_BeforeExecuteEventHandler^ value);

override BeforeExecute : IEvent<_dispCommandEvents_BeforeExecuteEventHandler,
EventArgs>
JScript does not support events.
Implements
_dispCommandEvents_Event.BeforeExecute
Remarks
Before executing the function that is declared to be the implementation of a command, the BeforeExecute event occurs. Any number of listeners may be registered for the event. Each listener executes when the event occurs.
If a listener claims it has implemented the command, no other listener or function should try to implement the command. A listener claims to have implemented the command by returning true for the handled parameter. If a listener only performs some extra function that was not supposed to be performed, such as making a log entry that the command fired or perhaps incrementing a counter displayed somewhere, then the listener returns false for the handled parameter.
Use CommandEvents.BeforeExecute.
Examples
Public Sub CommandEvents_BeforeExecute(ByVal Guid As String, ByVal ID As Integer, ByVal CustomIn As Object, ByVal CustomOut As Object, ByRef CancelDefault As Boolean) Handles CommandEvents.BeforeExecute
MsgBox("test")
End Sub
