Generating application events
The ExtensionClassBase class provides a method, named FireApplicationEvent, that can be used to generate an application event.
protected bool FireApplicationEvent(string eventName, bool sychronous, bool transactional, ref string result, ref ApplicationEventParameter[] parameters) { }
Properties
Property | Description |
---|---|
eventName | The name of the event to generate |
synchronous | Determines if the event handlers should be executed synchronously (True) or asynchronously (False) |
transactional | Determines if the event handlers should be executed in a

parameters | An array of named parameters passed to the event handlers |
Example
using Mongoose.IDO; using Mongoose.IDO.Protocol; using Mongoose.IDO.DataAccess; using Mongoose.Core.Common; [IDOExtensionClass("MyIDO")] public class TestFiringEvent : IDOExtensionClass { [IDOMethod(MethodFlags.None, "Infobar")] public void FireMyEvent(string Parm1, long Parm2, ref string Infobar) { ApplicationEventParameter[] ParmList = new ApplicationEventParameter[2]; string result = null; ParmList[0] = new ApplicationEventParameter(); ParmList[0].Name = "PString"; ParmList[0].Value = Parm1; ParmList[1] = new ApplicationEventParameter(); ParmList[1].Name = "PNumeric"; ParmList[1].Value = Parm2.ToString(); if (!FireApplicationEvent("MyEvent", true, true, out result, ref ParmList)) { Infobar = result; } } }
