Once you have started a web macro and you've got a Browser object to play with, it's time to get programmatic access HTML controls inside the web page. As any web developer should know, you can easily find elements inside a document using document.getElementById.
In the world of web automation things are a bit different; web macros need to access HTML elements in any web document and at any level of DOM hierarchy. The target HTML element can be inside frames/iframes loaded from various domains, subject of cross-frame scripting security restrictions (see my older posts: "When IHTMLWindow2::get_document returns E_ACCESSDENIED" and "When IHTMLWindow2.document throws UnauthorizedAccessException").
Here's a simple VBscript web macro that automates a Google search in Internet Explorer:
What is so great about the code above is the way FindElement method works: first it waits for the browser to load the HTML document then it searches for the element thru all frame/iframe hierarchy.Dim core
Set core = CreateObject("Twebst.Core")
Set browser = core.StartBrowser("http://www.google.com/")
Call browser.FindElement("input text", "name=q").InputText("codecentrix")
Call browser.FindElement("input submit", "name=btnG").Click()
Once an Element is found you can perform actions on it like: Click, RightClick, InputText, Check, Uncheck, Select, Highlight etc. What is even cooler than this, is that you don't have to write these statements by yourself. They will be automatically generated by Twebst Web Recorder which you can get for free:
