Internet Explorer Automation

[José Roca]

I have posted an example in my forum that explains step by step how to do it, It also clicks the submit button to perform the search.

If you're willing to use my new include files
http://www.jose.it-berater.org/smffo...p?topic=2819.0
instead of the ones provided with the compiler, this is what you will need:

#COMPILE EXE
#DIM ALL
#INCLUDE "exdisp.inc"
%USEHTMLWRAPPERS = 1
#INCLUDE "mshtml.inc"

FUNCTION PBMAIN () AS LONG

   LOCAL ie AS IWebBrowser2
   LOCAL pDoc AS IHTMLDocument2
   
   ie = NEWCOM "InternetExplorer.Application"
   IF ISNOTHING(ie) THEN EXIT FUNCTION
   ie.Visible = 1
   ie.Navigate UCODE$("http://www.google.com/")

   WHILE (ie.ReadyState <> 4)
      apiSleep 3
   WEND

   pDoc = ie.Document
   IF ISOBJECT(pDoc) THEN
      IHTMLDocument_setElementValueById(pDoc, "q", "test")
   END IF
   
END FUNCTION

Hmmm...

Included the MSHTML but now compiler is complaining about an undefined type Tag__userBITMAP do you know where that definition is located.

Thanks!

Ok, cool, I'll go and try that out right now.

However I didn't see anything that would allow me to directly access the DOM.

These methods and properties are in MSHTML.TLB. Use the COM browser to generate an include file for them.

Looking through sample files...

I found the Web Browser sample file that comes with PB and have been studying it. I looked through the WebBrowser.inc file and I saw the methods like Navigate, etc. However I didn't see anything that would allow me to directly access the DOM.

Does anyone know if there's a modified inc file with those extra methods built in to do something similar to the python code? Or any help on what I might be able to do to recreate that functionality.

So far I was thinking I could try programming my own method that parses the document and retrieves or sets values but I'm assuming creating a parser that can handle all the nuances of imperfect html code would be kind of hard.

I've been looking around the forums but haven't come across a way of easily interfacing with internet explorer and accessing the DOM. Below is an example that works in Python.

from  win32com.client import Dispatch
import time
ie = Dispatch("InternetExplorer.Application")
ie.Visible = 1

# Navigate to google
ie.Navigate("http://www.google.com/")

while (ie.ReadyState != 4): time.sleep(3)

ie.Document.getElementById("q").Value = "test"

The basic Idea is to be able to control internet explorer through PowerBASIC as if a user was entering information into forms and pressing submit buttons. I know its possible through OLE/COM but I have no idea where to start with that. Any ideas of what samples I can look at that might help me get started with something like this. Thanks.
