How to use the FireEvent method when a click does not work

Overview: While using QTP’s click method on a search WebElement earlier today, I had an issue with a WebTable’s populate event not being triggered as it should have. If you ever experience a similar problem with your application (not performing an expected action after a certain event occurs), don’t give up – and be sure to try the FireEvent method. Description: The FireEvent method is designed to trigger events in an application. Syntax: The Syntax for the FireEvent is: yourObject.FireEvent EventName,[x-optional],[y-optional],[BUTTON-optional] Valid Events: The events available when using the FireEvents method are:

• onchange
• onclick
• ondblclick
• onblur
• onfocus
• onmousedown
• onmouseup
• onmouseover
• onmouseout
• onsubmit
• onreset
• onpropertychange

The click method below was not working: 

Set mainPath = browser("CB").Page("CB")mainPath.WebElement("Search").Click 

but using the FireEvent did work: 

mainPath.WebElement("Search").FireEvent "ondblclick"

What is DOM? and How to use DOM properties in QTP?

What is DOM?

The Document Object Model (DOM) is a cross-platform and language-independent convention for representing and interacting with objects in HTML, XHTML and XML documents. Aspects of the DOM (such as its "Elements") may be addressed and manipulated within the syntax of the programming language in use. The public interface of a DOM is specified in its application programming interface (API).

how the browser display's objects in the browser
  DOM
   |-> Window
       |-> Document
             |-> Anchor
             |-> Link
             |-> Form
                  |-> Text-box
                  |-> Text Area
                  |-> Radio Button
                  |-> Check Box
                  |-> Select
                  |-> Button


QTP will be able to access to Internet Explorer Document Object Model (DOM) through which we will be able to access the HTML tags directly. Access to the DOM is performed using the .Object notation.

below function explains how to iterate all the tags in an Internet Explorer page. The function then outputs the inner-text of the tags (the text contained between the tags) to the Test Results using the Reporter object.

' we are using On Error Resume Next option because all the page elements might not have inner-text. 
 On Error Resume Next 
 Set Doc = Browser("CNN Interactive").Page("CNN Interactive").Object 
 ' Loop through all the objects in the page. 
 For Each Element In Doc.all 
 TagName = Element.TagName ' Get the tag name. 
 InnerText = Element.innerText ' Get the inner text. 
 ' Write the information to the test results. 
 Reporter.ReportEvent 0, TagName, InnerText
