How you can access all the properties, methods, and
events of the html object libray/webbrowser control
with using any webbrowser or winsock or inet control.
Most people believe that in order to use these objects
you have to load some sort of browser object
into memory..which has always been problem for me
since i know that IE has a lot of security holes.
the secret basically lies in one method of the
HTMLobject library. it is the ".CreateDocumentFromURl"
method
It goes something like this

'
dim start_time as long

'set a reference to the
'Microsoft HTML object library
'
'========================================
sub GetDocObject(byval sUrl as string )
dim objHTML as new htmlDocument
dim objDoc as htmlDocument
set objDoc=objHtml.CreateObjectFromUrl(sUrl)
'we now have to wait for the document to be set
'you probably want some sort of time out
'value in case of unforseen network problems
'otherwise you caught in the dreaded hanging
'loop
start_time = getTickCount 'API call
while objDoc.readystate <> "complete"
'5 second timeout value
if (gettickcount - start_time) > 5000 then
exit sub
end if
doevents
wend
'reaching this point in code means
'the document object has been set
'and you can handle it any way you
'wish accessing its links, tables..whatever
'for example
dim lcnt as long
dim upper as long
dim oLink as htmlAnchorElement
upper = objDoc.GetElementsByTagName("A").length -1
if upper > 0 then
for lcnt = 0 to upper-1
set oLink = objDoc.GetElementsBytagName("A")(lcnt)
list1.additem oLink.href
next lcnty
