There are many samples about this issue, so why did I write a new one? In my humble opinion, in other articles, the missing part is to attach its event at runtime. So in this article, we will build a .NET component, mark it as a COM visible component, use it at runtime in VB6 and attach to its events.</p> <p><a href="https://www.codeproject.com/Articles/37127/Internet-Explorer-Late-Binding-Automation" rel="nofollow noreferrer">https://www.codeproject.com/Articles/37127/Internet-Explorer-Late-Binding-Automation</a></p> <p>Most developers often need Internet Explorer automation, which basically means opening a browser, filling some forms, and posting data programmatically.</p> <p>The most common approach is to use shdocvw.dll (the Microsoft Web Browser control) and Mshtml.dll (the HTML Parsing and Rendering Component), or Microsoft.Mshtml.dll which is actually a .NET wrapper for Mshtml.dll. You can get more information about Internet Explorer - About the Browser here.</p> <p>If you pick the above method and DLLs, let's see some of the problems you may have to deal with:</p> <p>You have to distribute these DLLs because your project would be dependent to these DLLs, and this is a serious problem if you cannot deploy them correctly. Simply do some Googling about shdocvw and mshtml.dll distributing problems, and you'll see what I'm talking about. You have to deploy an 8 MB Microsoft.mshtml.dll because this DLL is not part of the .NET framework. In this case, what we need to do is use a late binding technique. Writing our own wrappers for the above mentioned DLLs. And of course, we'll do this as it is more useful than using these DLLs. For instance, we won't need to check if the document download operation is complete because IEHelper will do this for us.</p>
